Cold pressed oil is the edible vegetable oil produced by pressing oil at a low temperature (40-60℃). The cold pressed oil is better in color. But the cold press oil press is less fragrant. Cold pressed oil does not foam when it is eaten, and is suitable for frying.

Hot pressed oil is a product oil formed by physical pressing after high temperature (120-130℃) frying. The vegetable oils consumed in our daily life are mostly hot pressed oil. The hot pressing features high oil output and simple operation. The hot oil is pure and fragrant, especially the oil of sesame and peanuts, which are rich in oil and more fragrant.

Guangxin oil press machine is suitable for both cold oil pressing and hot oil pressing.

Solvent For Silicone

Silica gel alias: Silicic acid gel. It is a highly active adsorbent material and an amorphous material. 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 silica gel 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. Silica gel is classified according to its pore size: macroporous silica gel, coarse pore silica gel, B-type silica gel, fine pore silica gel, and the like.

Dissolution method for silica gel: silicone rubber solvent has excellent water resistance and is insoluble in water, but it can be dispersed in water in subdivided form. Some silicon rubber is still soluble in some non-polar solvents (most of which are swelling), which can be dissolved first and then emulsified into emulsion, and the solvent can be evaporated out.

General rubbers such as common neoprene, nitrile rubber, natural rubber, synthetic natural rubber, butyl rubber, etc., have a large molecular weight, and need to be reduced in molecular weight by melting rubber to be dissolved in an organic solvent. Different glues have different solvents depending on their polarity.

Polyurethane is also a rubber, but it is formed by physical crosslinking. Linear or differentially branched polyurethane resins generally require aprotic, highly polar solvents such as DMF, DMAc, and NMP.

Characteristics of rubber dissolution: Solid unvulcanized rubber can be dissolved in some organic solvents, but as a polymer material, its dissolution process is significantly different from that of solid low molecular materials. First, the dissolution process is slow and cannot be accomplished in a flash like a low molecular material. Second, the whole process is divided into two phases: first swelling and then dissolution.This time needed is particularly long.

What is the difference between automatic high frequency welding machineand heat-sealing machine heat sealing machine? We briefly introduce the different principles between high frequency voltage processing and hot sealing machine, the different ranges of processed products, as well as the advantages and disadvantages of high frequency processing and hot sealing machine processing, so as to help customers understand the specific differences between high frequency processing and hot sealing machine processing.

Different principle:

High frequency processing principle: as we have said earlier, "automatic high frequency welding machine welding principle" the high frequency magnetic field energy emitted by high frequency tube oscillation, and the conduction effect in the processing of plastic parts, high frequency energy permeability material molecules inside, quickly make plastic molecule polarization of plastic material, material molecules arranged in the same direction with high frequency electric field direction, due to the molecular polarization, so as to achieve solid fusion.

Heat sealing machine principle: we talking about heat sealing in a narrow sense, namely is to use temperature condition, made by processing plastic sealing parts, heat close to the melting point of plastic material, make it into a viscous flow state, at the same time, to a certain pressure and make the two layers of plastic membrane fusion, cooling after a period of time, plastic material can maintain a certain strength and sealing performance. Guaranteed the commodity in the packing, the transportation, the storage and the consumption process may withstand certain external force, the commodity does not crack, the leakage, achieves the protection commodity the goal. The principle is simple, and the operation is simple.

Different product range:

High frequency sealing machine range: high frequency processing, also known as voltage processing. The main target is relatively thick plastic materials, or plastic products processing requirements precision, firmness and other processing properties of the higher case, the need for high frequency voltage processing.

Advantages and disadvantages of automatic high frequency welding machine:

High cycle processing advantages: processing process, all working parameters precise control high cycle machine, the processing of plastic parts of the product whether in sealing, firmness, appearance, or precision is absolutely perfect. The processing speed of the product is medium.

Using the high frequency principle, the operation is a little complicated, the cost of the machine is higher than that of the heat-sealing machine.

Advantages and disadvantages of hot sealing machine processing:

Advantages of hot sealing machine: low cost, simple operation, easy for employees to use, medium processing speed.

Heat sealing machine processing products: due to the principle of the heat-sealing machine, we can know, heat sealing machine is mainly suitable for the processing of thin plastic film material, product packaging requirements is not very high-end.

Because of its completely by temperature to heat plastic parts, achieve the goal of welding, the temperature is difficult to accurately grasp the optimum temperature for possible because machine time for a long time, cause temperature too high or too low adverse phenomenon, lead to welding unstable heat-sealing products, sealing, or plastic glue processing, makes the product welding deformation, rough, not beautiful. At the same time, the overall production efficiency of the machine decreases.

  Zhiyun Crane 3 LAB

 Weebill LAB 

What's up guys I'm Jimmy from elegant screen works and today we're going to take a look at the DSLR stabilizers to crane 3 lab and the smaller we be lab from Eugene Tech enjoy since our team specialized in creating short cinematic action films on a low budget these gimbals are the perfect choice for us they include a tripod that also doubles as a handle works amazing to get bad sturdy double hand grip very ergonomic very easy to use and in context to our short film it allowed us to really get that steady high-speed cinematic footage without paying big bucks for large cranes dolly tracks and big crew to operate all that equipment for us there was a one-man job and it worked great without running gun style of film making both gimbals come equipped with an integrated camera control system this system allows you to hook up your phone or tablet to wirelessly use it as an external monitor or remote to control both the settings in the camera and the settings in the gimbals the camera control system in these gimbal's can also be used to operate the synchronous zoom and focus controller which is easily operated through the controls on the gimbal itself or through the connected phone now with a gimbal you really can't adjust the focus while shooting without messing up your shot the accessible focus control gets rid of that problem.

Permanently one thing that we also liked about these gimbals was the ability to connect monopods the extendable monopod allowed us to shoot those high angle jib shots while shooting our action movie we wanted to really push these gimbals to their absolute limits and what is a good action movie without that's right car chase roll the car chase footage . I know what you're thinking this was all done on a closed Road the cameraman was securely buckled up the whole time remember guys safety always comes first now that we got all that stuff out of the way I'm gonna go a little more into detail about what actually did here we got our photographer and gimbal operator

gust strapped to the back of her car and you use the crane 30-lap with the monopod tightly secured with the wrist strap, of course, remember guys but I said about savory first that also goes for your camera equipment you don't want to drop this bad boy in the pavement you lock the monopod between his legs and me as a director was able to see in the front seat using my phone as a monitor

to observe everything that was going on through the camera control system easily and look at how smooth this footage turned out even when hanging out of the side of they are amazing.  Even though our photographer is a strong man according to himself at least the crane three with our camera and lens setup is a heavy rig you will get tired after a long day of shooting, that's where the we built really shines with a lighter setup the waybill is both smaller and lighter than the crane 3 but size does not always have to matter here since stabilization with this rig comparability still is very good.

0.8 Series CCS Wire

Origin of new material development

0.8mm series copper-clad coated ground 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 stainless steel wire (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 copper plated steel 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.
