As the phenomenon of welding spatter is very common, the use of anti-spatter coating for welding is also very extensive. For general structural parts, the type of welding anti weld spatter coating has little effect, as long as it can effectively prevent welding spatter from adhering to the working surface in the welding process. However, for some key products and workpieces, such as high pressure vessels, if the anti-spatter coating contains too many harmful elements, it may cause spot corrosion, intergranular corrosion, etc. It will cause leakage in the subsequent operation of the equipment and lead to malignant accidents.

The selection of anti weld spatter coating also needs to be combined with the whole production process and process method. The process flow and process method mainly depend on the part after welding. At present, the technological process of structural parts is mainly divided into two categories: one is post-processing painting, the other is post-coating processing. If it is painting after processing, it must be cleaned before painting in order to remove rust and spray paint because cutting fluid will be used in the process of mechanical processing.

The type of anti weld spatter coating used in welding of the structure parts of the processed coatings has little effect. Even if oil-based anti-spatter coating is used, it can be completely removed by the cleaning process before painting, and the quality of the spray paint will not be affected. If the coating is processed or not processed, the use of oil-based anti weld spatter coating will bring some problems. Direct shot blasting treatment of structural parts can remove surface rust. But it is difficult to remove oil-based anti weld spatter coating coated on the weld seam of the workpiece. It will adsorb on the surface of the pellet, which causes pollution on the surface of some workpieces with oil stain, seriously affecting the adhesion of the paint film. In order to prevent the influence of oil-based anti-splash coating on subsequent painting, it is necessary to increase the cleaning process and carry out the necessary cleaning of the workpiece. Increasing the cleaning will bring a series of problems, such as production area shortage, cost increase, sewage discharge and so on. Therefore, for the workpieces processed or unprocessed after painting, oil-free anti weld spatter coating should be selected during welding, and water-borne or powder anti weld spatter coating should be used.

Palm kernel oil expeller is a widely planted oil crop in the tropics. Not only the palm fruit but also the palm kernel can extract oil. In general, the palm oil expeller machine is mainly used to extract palm oil, which is called red palm oil. Palm oil machine is mainly used to extract palm kernel oil, also known as white palm oil.

Palm kernel oil expeller machine is the main equipment for extracting palm kernel oil. The palm kernel oil extraction machine can squeeze most of the oil from the palm oil crop under high pressure through mechanical pressure.

If your raw material is a clean palm kernel, the steps you take to extract palm kernel oil are as follows:

First, separate the palm-shell and palm-kernel by kernel separating equipment.

Secondly, break the palm kernel into small pieces, and the surface area of oil is increased after crushing, which is conducive to the transfer of temperature and moisture during steaming and stir-frying.

Thirdly, the purpose of steaming and stir-frying is to completely destroy the palm kernel cells through the action of temperature and moisture. To denature the protein, accumulate the fat, reduce the oil viscosity and surface tension, adjust the elasticity and plasticity of the billet, and passivate the enzymes.

Fourth, put the treated oil into the palm kernel oil pressing machine, palm kernel oil extraction machine USES the principle of mechanical external force to extract palm kernel oil:

Fifth, the crude palm kernel oil obtained after pressing is generally not clean, there are a lot of impurities. We finally process simply to extract relatively clean palm kernel oil through the leaching or filter equipment;

If your raw material is a pressed seed cake from the palm oil crushing plant, you need to do this: after the crushed cake is broken, send it to the fiber separator and fiber polishing roller for fiber separation. After these simple treatments, you can get a cleaner palm kernel, and the rest of the process is the same.

Characteristics of palm kernel oil press:

Easy operation and maintenance;

High capacity;

High oil yield;

Model PRO-B3,with capacity 1000-2200 kg/hour

About White bean

White bean, also known as the broad bean, fava bean, faba bean, field bean, bell bean, or tic bean, is a species of flowering plant in the pea and bean family Fabaceae. It is of uncertain origin and widely cultivated as a crop. Horse bean, Vicia faba var. equina Pers., is a variety recognized as an accepted name.

White beans are widely planted in Algeria, China, Colombia, Croatia, Ecuador, Egypt, Ethiopia, Greece, India, Iran, Irap, Iraq, Italy, Japan, Luxembourg, Malta, Mexico, Morocco, Nepal, Netherlands, Peru, Portugal, Spain, Sudan, Sweden, Syria, Turkey.

Broad beans were a major food of old Mediterranean civilizations, particularly for the Romans and Ancient Greeks.

The beans can be fried, causing the skin to split open, and then salted and/or spiced to produce a savory, crunchy snack. These are popular in China, Malaysia, Colombia, Peru (habas saladas), Guatemala (habas), Mexico (habas con chile), Gilan (North of Iran) and Thailand (where their name means "open-mouth nut").

In some Arab countries, the fava bean is used for a breakfast dish called ful medames.

Fava beans are common in Latin American cuisines, as well. In central Mexico, mashed fava beans are a common filling for many corn flour-based antojito snacks such as tlacoyos. In Colombia, they are most often used whole in vegetable soups. Dried and salted fava beans are a popular snack in many Latin countries.

0.8 Series  Copper Coated Stainless Steel Wire

Origin of new material development

0.8mm series copper-clad round wire is a new type of material developed by our Company to replace pure copper. Because it has the advantages of high strength, low price, high corrosion resistance and high conductivity of copper, and meanwhile its comprehensive performance is high and its cost is more economical than pure copper grounding device, it has been widely used in UHV lines, petrochemical industry, nuclear power and high-speed railway, especially in key projects in recent years.

Copper-clad steel:

The material in which the surface of a steel core is uniformly coated with copper includes copper-clad steel bars (for vertical grounding electrode only), copper-clad steel tape, and copper-clad steel wires (including round wires and stranded wires). According to the production process, it can be divided into continuous casting copper-clad steel and electroplating copper-clad steel.

Development of copper-clad steel grounding device

With the increasing voltage level of power lines and the increasing capacity of the system, higher requirements are put forward for the safety and reliability of grounding devices.

The traditional method in foreign countries is to use pure copper as the grounding material, but pure copper is expensive and it is a strategic resource, which is not suitable for being massively used as grounding devices in China. From 1910 to 1955, National Bureau of Standards (NBS) conducted corrosion resistance studies of grounding bodies. 36,500 samples collected at 128 test sites throughout the United States represented 333 metal materials consisting of iron, non-ferrous metals and protective coatings, respectively. The test results show that only steel bars and stainless steel bars with copper plating thickness over 0.5mm can be accepted.

In addition, continue the statistical data of 8 to 30 years and take the test results of 43 copper samples in different soils, 41 of which were calculated, to get the 0.17mm average pitting depth of 30 years. Therefore, some international standards have determined the thickness of copper coating of copper-clad steel material to be at least 0.25 mm. Considering the hard friction during construction, it is suggested that the thickness of copper coating be defined as 0.5-0.8 mm.

In China, copper clad(copperweld) steel materials are widely used in substation grounding grids in areas with high soil resistivity. Because of the characteristics of UHV project, such as high voltage level, large capacity and short power cut window period, combined with the corrosion intensity of groundwater in the area, copper-clad steel grounding devices have been applied in UHV lines and many UHV lines in China use copper-clad steel materials as grounding bodies.

Comparison between copper-clad steel grounding and traditional hot-dip galvanized steel grounding device

1. Corrosion rate comparision
   Annual corrosion rate of grounding materials in some place of Beijing and Tianjin

The test results show that galvanized steel has the most serious corrosion and its corrosion rate is more than 50 times higher than that of pure copper; the corrosion degree of stainless steel is much lower than that of pure copper and copper-clad steel, showing good corrosion resistance; as a copper-steel composite material, the self-corrosion potential of copper-clad steel in soil is basically the same as that of pure copper, and its corrosion rate is the same as that of pure copper; the corrosion rate of the electroplated copper-clad steel with thinner coating is higher than that of the continuous casting copper-clad steel with thicker coating.

2. Analysis and comparison of physical performance in short circuit

If the conductivity of copper were 100% and the conductivity of standard 1020 steel were only 10.8%, the conductivity of copper would be about 10 times that of steel. However, the conductivity of the 30% conductivity copper-clad round wire would be 30%, and the conductivity of the 40% conductivity copper-clad round wire would be 40%, which would be far better than the steel grounding body. Especially under skin effect, the conductivity of copper-plated strands at high frequencies would be much better than that of steel, that is, the conductivity of copper grounding body would be better than that of steel grounding body. The melting point of copper is 1083℃ and the maximum allowable temperature during short circuit is 450℃ ; the melting point of steel is 1510℃ and the maximum allowable temperature during short circuit is 400℃. Therefore, when the grounding body has the same cross section, the copper-clad steel grounding material has better thermal stability.

3. Economic comparison

According to Appendix D of Technical Conditions for Copper-clad Steel for Grounding in Electrical Engineering, the corrosion rates of copper clad steel in different soils are calculated according to the reference values in table. Corrosion rate of pure copper under different soil corrosion grades (mm/a)

The 0.8mm copper plating thickness is enough to meet the requirement of 60 years of service under the grade of III extremely strong corrosion.

The corrosion rate of galvanized steel is nearly 50 times that of copper-clad steel under the same soil conditions, and the grounding body should be overhauled after being used for 3-5 years.

The State Grid has accounted the UHV tower according to the drawings: after the investigation of the market price of material during the construction, the market price of the copper-clad-steel grounding body is calculated at RMB 20 /m, the market price of φ12 galvanized-steel round steel grounding body is calculated at RMB 6 /m and the grounding body laying is calculated according to the grounding construction drawing. During the 30-year whole life cycle, galvanized steel is overhauled every 5 years, of which the cost of material is RMB 20 /m for copper-clad steel and RMB 36/m for galvanized steel, that is, only material cost can be reduced by 80%. Galvanized steel can be overhauled and replaced six times. If the construction cost is RMB 70 /m3 for earthwork and stone works and each base tower is calculated by 23 m3 for excavation, RMB 9660 per base tower will be saved.

Copper-clad steel construction

The horizontal laying of the copper-clad steel grounding device is the same as that of the ordinary galvanized round steel, where only the connection method is changed to hot-melt welding, which has reduced the contact resistance between the joints and is more conducive to the release of lightning current.

Exothermic welding, also known as "aluminum heat welding", is a simple, high-efficiency, high-quality metal joining process that has been mass-produced and used in China in recent years. Exothermic welding uses chemical reaction heat of metal compounds as heat source and through superheated (reduced) molten metal or indirect heating, a certain shape and size of the melted joint is formed in the cavity of the special graphite mould, which meets the engineering requirements, and finally through cooling and condensation, the welding process is realized. At present, exothermic welding has generally replaced the mechanical connection between metals in the past.

Advantages of copper-clad steel

1.It has strong corrosion resistance and will not be disjointed, warped or cracked. The corrosion in the grounding body of the grounding grid is reduced, which has improved the overall operational safety of the equipment;

2. It has good electrical conductivity and stable electrical performance;
3. The copper layer and the steel bar achieve molecular bonding, and the grounding bar will not break down when it penetrates into the soil.
4. The copper-clad-steel grounding material used has high efficiency of reducing the resistance, and the length of the horizontal grounding body is reduced by 1/3 for the design of the high-resistance section, greatly reducing the excavation amount of the earthwork;
5. The design and use of exothermic welding technology is very suitable for the needs of field construction, greatly improving work efficiency and effectively shortening the construction period.

Performance parameters of copper-clad steel wire

Copper layer thickness:0.8mm; tensile strength: greater than 500MPa; copper-clad steel bent 180° without peeling off copper layer.

Specification of 0.8mm series copper-clad round steel: Soft copper-clad round bars are generally packaged in hanks or rolls, 100 meters per roll, easy to transport, suitable for laying of large grounding grids and horizontal grounding lines.

Usage:key projects, large grounding grids and horizontal grounding wires in industries with higher lightning protection requirements, etc.

Silica gel alias: Silicic acid gel. It is a highly active adsorbent material and an amorphous material. The main component of silica gel is silica, which is chemically stable and does not burn. It has an open porous structure with strong adsorption and can absorb a variety of materials. When dilute sulfuric acid (or hydrochloric acid) is added to the aqueous solution of water glass, it will become hydrous silicic acid gel and become solid. The dissolved electrolyte Na+ and SO4 2-(Cl-) ions are removed by water washing. Silica gel can be obtained after drying.

Generally speaking, silica glue can be divided into organic silica gel and inorganic silica gel according to its chemical properties of silica gel and its components.

Inorganic silica gel is a kind of highly active adsorption material, which is usually prepared by the reaction of sodium silicate and sulfuric acid and a series of post-treatment processes such as aging and submerge in acid. Silica gel is an amorphous substance. Its chemical formula is mSiO2. nH2O. It is insoluble in water and any solvent, non-toxic, odorless, stable in chemical properties, and does not react with any substances except strong alkali and hydrofluoric acid. Different types of silica gel have different micropore structure due to different manufacturing methods.

The chemical composition and physical structure of silicone gel glue determine that it has many other characteristics which are difficult to be replaced by other similar materials: high adsorption performance, good thermal stability, stable chemical properties, high mechanical strength, etc. It is used by families as desiccant, humidity regulator, deodorant, etc., by industry as oil hydrocarbon decolorizing agent, catalyst carrier, variable pressure adsorbent, etc., and by fine chemical industry as separation purifier, beer stabilizer, paint thickener, toothpaste friction agent, polish remover, etc.

Organic silica gel is an organosilicon compound that contains Si-C bonds, and at least one organic base is directly connected to the silicon atom. Traditionally, those compounds that connect the organic base to the silicon atom via oxygen, sulfur, nitrogen, etc., are also considered as organosilicon compounds. Moulded silica gel is a little more complex with irregular shapes, including silica gel bowl, silica gel ice lattice, silica gel cake mold and so on.

The pewter pins are very popular because of its cheap cost and quick delivery time as well as the great present on the full 3D effect. While as the world strict requirement on the lead content of the metal gifts, the pewter lapel pin has been used less and less. Actually, we do have the #0 pewter which could meet the lead content requirement set up by different countries or associations, but the cost of this kind of pewter is much expensive. For some design, it would be even more expensive than bronze material. But the unique presenting way for the full 3D or hollow designs makes the spin cast pewter lapel pin irreplaceable.

There are two things we'd like to share about the pewter pins:

• First, the pewter is pretty soft. So if they are many cutouts on the designs and the metal lapel pin would be used separately without any background support, then we suggest you don't choose the pewter process for your lapel pin in case it breaks easily.
• Second, if the metal lapel pin would be used to assemble with other item and requires very accurate shape or size, then we don’t suggest you choosing pewter process as well since for the spin cast lapel pin, the mould is silicon. It's not as stable as the steel mould.

Hard Gold PCB, immersion gold pcb, is to immerse the board in the plating tank and apply current to form a nickel-gold coating on the copper foil surface of the board. The electro-nickel gold is characterized by high hardness, wear resistance and oxidation resistance. Widely used in applications.

Introduction to Hard Gold PCB Technology:

1. Purpose and role: gold as a precious metal, has good weldability, oxidation resistance, corrosion resistance, small contact resistance, good wear resistance of the alloy and so on;

2. At present, the electroplating gold of the circuit board is mainly a citrate gold bath, which is widely used for its simple maintenance and simple and convenient operation;

3. Water gold content is controlled at about 1 gram / liter, PH value of about 4.5, temperature of 35 degrees, specific gravity of about 14 waves, current density of about 1ASD;

4. The main added drugs are acid-adjusted salt and basic-adjusted salt for adjusting pH value, conductive salt and gold-plated supplement additive for adjusting specific gravity, and gold salt;

5. In order to protect the gold cylinder, a citric acid dip tank should be added in front of the gold cylinder to effectively reduce the pollution of the gold cylinder and maintain the stability of the gold cylinder;

6. After the gold plate is electroplated, a pure water wash is used as the recovery water wash. At the same time, it can also be used to supplement the liquid level of the gold cylinder evaporation change. After the water is washed, it is connected with the second-stage counter current pure water wash. After the gold plate is washed, the alkali liquid is put into 10 g/shdter. To prevent oxidation of the gold plate;

7. Gold cylinder should use platinized titanium mesh as anode, generally stainless steel 316 is easy to dissolve, resulting in nickel-iron-chromium and other metal pollution gold cylinder, causing plating white, exposed plating, blackening and other defects;

What is Immersion Gold Plating:

Everyone chooses immersion gold plating, then what is immersion PCB gold plating, we say the whole plate gold plating, generally refers to "electroplating gold", "electroplated nickel gold plate", "electrolytic gold", "electric gold", "electric nickel plate", soft gold and the distinction between hard gold (usually hard gold is used for gold fingers), the principle is to dissolve nickel and gold (commonly known as gold salt) in chemical potion, dipping the board in the plating tank and turning on the current on the PCB. A nickel-gold plating layer is formed on the surface of the copper foil, and the nickel-gold alloy is widely used in electronic products because of its high hardness, wear resistance, and oxidation resistance.

Electric gold standard: nickel thickness 3-5um; gold thickness 0.25-1.5um; gold thickness minimum 3U''.

The Application of Hard Gold PCB

Hard Gold PCB is widely used in intelligent AI, entertainment, educational robots or other industrial intelligent equipment to expand and contract, rich in change action, frequent separation and contact of local ports of the device, which requires good wear resistance of the PCB at the contact area of the port. Sexual and not easily oxidized.

Mounting magnets are comprised of powerful permanent magnets set inside steel cups or channels with countersunk holes or threaded features for holding applications. The steel structure redirects the magnetic field from the back-side of the magnet, making it much more stronger in terms of pull force, and protects the magnetic material from damage during use. Commonly used mounting magnets include Hook Magnets, Threaded Magnets, Countersunk/Counterbore Pot Magnets, Channel Magnets and Rubber Coated Magnets.

Mounting Magnets can double the strength of which you get with the magnet alone, as the steel cup attracting to it is magnetized by the magnet, giving much more pull force. The pull force numbers we list for each product is the force required to pull the mounting magnet straight away from a steel surface.

In fact, how much force a mounting magnet can hold depends on a few factors. When loading the magnet in a different orientation, for example, vertically stuck onto a wall, the weight it can hold up is usually lower than the listed pull force number. Moreover, the friction between the surfaces, the shape of what is being held up, and other factors also contribute to differences of the results.  

Strong mounting magnets are often used as fishing magnets to retrieve objects that are lost underwater with magnetic parts or steel components. Mounting magnets with different features, such as hook, threaded and countersunk, can be widely used for holding, hanging, and attaching objects in different projects.

From the following procedures, Redstar develops and implements a complete and systematic account receivable risk management system to ensure that the management work runs on a benign track:

1.Accurate and timely customer background survey.

Generally, it includes the following aspects: whether the customer has a fixed place for production and operation, statutory business registration, good credit reputation; Whether the product has a good market prospect; What is the scale of the customer's production and operation and the expected procurement scale? Whether there is a debt dispute in the customer's history and the reasons for disputes; The basic situation of the person in charge of the customer enterprise, the head of the procurement and finance department; The basic situation of the branch of the customer and the affiliated company.

2. Objective and real customer credit survey.

Through detailed investigation and analysis of the customer's business scale, business cycle, liability structure, and property rights ratio, RedStar evaluates the customer's highest credit limit, the longest credit period, and the default procedures.

3. Improve contracts and other written agreements.

It is necessary to establish relevant written treaties between the credit-selling enterprises and the customers, so as to make specific operational provisions for a series of procedures such as receiving orders, delivery receipts, payment settlement, and financial reconciliation.

4. Daily monitoring and management of accounts receivable risk.

Follow up on the customer's business situation and grasp the dynamics of accounts receivable in a timely manner. Especially for overdue accounts, efforts are made to increase the efficiency of the collection of accounts receivable while increasing dunning. For accounts receivable that have not yet expired, supervision should not be loose in case new defaults occur, by doing so, the security of accounts receivable is on the highest level.
