Electric forklift is a forklift that operates by electricity, most of which are operated by storage battery. Storage batteries are one kind of batteries. Their function is to store limited electric energy and use it in suitable places. Its working principle is to convert chemical energy into electrical energy. This kind of battery is also contained in the battery of electric forklift truck. Note: Batteries should not be laid out horizontally! Because the inside of the battery is usually 22-28% dilute sulfuric acid. When the battery is being discharged, the electrolyte can submerge the plate and there is still a little space left. If the battery is transversely discharged, a part of the plate will be exposed to the air, which is very harmful to the plate of the battery. Moreover, the observation holes of the general battery or the top of the battery have vents to communicate with the outside world, so the electrolyte can easily flow out of the battery by transverse discharging.

Electric forklift truck can be divided into: four-way electric forklift truck, electric pallet stacker truck, push electric stacker truck, electric tractor, three-point electric forklift truck, four-point balanced forklift truck, forward-moving electric forklift truck, three-point Mini Forklift truck, ammunition balanced forklift truck, special electric forklift truck for cold storage, electric explosion-proof forklift truck, walking balanced forklift truck, electric oil drum stacker truck, three-point balanced forklift truck. Electric series material handling equipment, such as legged stacking truck, station crane, four-fulcrum legged stacking truck, four-fulcrum wide-leg stacking truck, forklift basket picking truck, four-fulcrum double-deck stacking truck, electric tractor, picking truck, etc.

Electric forklift truck is driven by electricity. Compared with internal combustion forklift truck, it has the advantages of no pollution, easy operation, energy saving and high efficiency. With the development of economy and the improvement of environmental protection and energy saving requirements, electric forklift truck develops rapidly. Market sales are increasing year by year. Especially in the port, storage and tobacco, food, textile and other industries, electric forklift is gradually replacing diesel forklift.

How to dry silicone？

Here offer pieces of information about how to use quick dry sealant or fast drying silicone glue.

1.Use: A single group of silicone glass glue can be used immediately. It is easy to type it from the bottle with a glue gun, and a spatula or wood chip can be used to trim the surface.

2.Adhesion time: the curing process of silicone rubber is developed from the surface to the inside. The drying time and curing time of different characteristics of silica gel are different. So if you want to fix the surface you have to do it before the glass gel sheet is dry (acid glue, neutral and transparent glue should be in 5-10 minutes, neutral color glue should be in 30 minutes generally). If the color paper is used to cover a certain place, after coating, it must be removed before the skin is formed.

3.Curing time: the curing time of glass glue increases as the adhesive thickness increases. For example, the acid glass glue of 12mm thickness may take 3-4 days to solidify. But within about 24 hours, the outer layer of 3mm has been solidified. When glued to glass, metal or most wood, it has an anti-stripping strength of 20 pounds per inch at room temperature after 72 hours. If the use of glass glue is partially or completely sealed, the solidification time is determined by the closeness of the seal. In a place of absolute closeness, it is possible to remain uncured forever. If the temperature is raised, the glass will soften. The gap between metal and metal bonding should not exceed 25mm. In all kinds of bonding situations, including airtight conditions, the adhesion effect should be thoroughly checked before the equipment is used. In the curing process, acid glass glue will produce a smell due to the volatilization of acetic acid, which will disappear in the curing process. There will be no smell after curing.

4.Adhesion: A. Wipe the surface of the metal and plastic completely, remove the oil, and then wash the whole surface with acetone except for the plastic. If it is rubber surface, apply sandpaper and rub it with acetone. Please observe the precautions when using acetone. B. Apply the glass glue evenly on the surface of the prepared object. If the two surfaces are glued together, place one side properly first and press the other side to squeeze out the air, but be careful not to extrude the glass. C. place the bonding device at room temperature and wait for the glass to solidify.

5.Seal: the silicone glass sealant also can be used for sealing purposes according to the above steps. Squeeze the glass glue into the joint or the seam so that the glass glue is in full contact with the surface.

6.Cleaning: before curing, the glass glue can be erased with a cloth or paper towel. After curing, it should be cleaned with a scraper or xylene, acetone and other solvents.

The key of how passive house performs lays on well designed ventilating which can not only filtrating too much moisture in the air and peculiar smell but pollen and dust, providing clean and fresh air for rooms. If you open the window for ventilation, a lot of quantity of heat will be lost, and the loss is more than the total quantity of heat that a passive house needs. Under most climate conditions, passive house wants certain heating but the quantities are small, which can be realized by ventilating. Through heating coil to warm up fresh air, the heating needs left can be met, and that is the concept of the fresh air system of passive house for supplying heating.

Principle of the ventilation of passive house

The basic principle of the ventilation of passive house: the muddy air in kitchen and bathroom is extracted (air exhaust) and the fresh air will be delivered in to where people live (air supply), and automatic air exhaust can be realized in hallway. For example, the standard of fresh air is 20m2/h for one person and per capital living space is 30m so that the quantity of air supply should be 1m/2(m?h). the highest temperature is limited as 50 ℃ and the corresponding heat load is 10W/m* in order to avoid the peculiar smell produced by excessive temperature causing the dust to be burned, meeting the requirement of heat supply.

The functions of ventilating

Ventilating, able to recycle the heat efficiently, emphasizes its own main functions: it can change the indoor air,  which can control the air humidity in case of mildewing; it can stop the accumulation of pollutants and it can remove the peculiar smell. In addition, there are additional functions: it can regulate the indoor air and clean the air ( acts as filter) to eliminate PM2.5; it can work as humidifying and dehumidification. Passive house applies the ventilating recycling the heat efficiently, lowering the heat loss, increasing the temperature of fresh air and enhancing the degree of comfort indoors. Meanwhile, the ventilating of passive house regulates the humidity indoors ( the optimal range is with relative humidity of 35%-55%), over or lower will do harm to health, especially the skin and respiratory system. If the temperature is too high, it will go mouldy; if the the temperature of internal surface is lower than 12.6℃, it will be liable to mildew; instead,  the temperature of internal surface is lower than 9.6℃, condensation will happen. Too low temperature will possibly damage the floor or musical instrument.

Thenow will strive to offer you hrv dehumidifier with good quality.

Here offer pieces of Information On Chemical Composition Of Silica Gel.

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 gel can be divided into organic silica gel and inorganic silica gel according to its properties and 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 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. 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.

After knowing information above,you may have a deeper understangding of silica gel composition and silica gel chemical formula.

Automated assembly refers to the assembly of products through the use of automated machinery or assembly robots and systems. Only a small part of the work is controlled by people. In most cases, automation is often used to produce a standardized product assembly line for a series of specific actions or activities. Automated assembly is an important part of many technology companies and medical research plants.

Today, automation components in many factories are used to create components and then assemble a variety of products, from the food industry to the electronics industry. Workers only need on-site supervision to ensure that the assembly line process can be maintained and their ability to produce thousands of high-quality products can be maximized in the shortest possible time.

Medical research facilities and food processing factories often use automated assembly processes in areas where human contact may lead to danger or product contamination. Manipulators or robotic equipment are used to deal with the sealed environment in the above product systems to minimize this risk.

Large manufacturing companies use larger automated assembly equipment, including large-scale products such as automobiles that use heavy robotic equipment. In these environments, except that only a few workers operate in the central control center, the other processes are to assemble vehicles independently using assembly systems. Although this form of manufacturing looks more like a replacement for manual work, it reduces casualties and human failures.

In recent years, with the prosperity of the domestic electronic industry, the industry of our automated assembly machine has also taken advantage of the rising trend. At the same time, many manufacturers are gradually carrying out automation reform, replacing manual labor with machines, so many enterprises are rushing to introduce automation equipment, but its main equipment is automated assembly machine.

Features of the automated assembly machine:

Firstly, the automated assembly machine saves the cost to the enterprise. Because it can operate efficiently without human being, as long as one person feeds, it can be the efficiency of many people and save a lot of labor cost effectively.

Secondly, the automated assembly machine has good versatility and can store many sets of programs. As long as the customer changes the product size, the product program can be changed.

Thirdly, when designing, we have designed more product procedures, so it is convenient to change the products when making later production. By simply replacing the fixture, the production can be realized by simple programming, which is very convenient for enterprises to produce.

Fourthly, we all adopt the imported track to effectively ensure the stability of the machine and eliminate the adverse effects caused by human factors. The imported components also effectively ensure the stability of the machine.

Fifthly, with efficiency and convenience, an automated assembly machine can save about 5 people.

Lubricant is an indispensable additive in PVC processing. For lubricants, the commonly referred function in industry's can be summarized in two points, they are: it reduces the friction pre-melting particles of polyvinyl chloride and the macromolecules in the polyvinyl chloride melt. It is actually the most typical summary of the two aspects of lubricant action (internal and external lubrication). Then, we will discuss and analyze the internal and external lubrication of PVC lubricant from the technical level for you.

1.Internal lubrication

In terms of PVC, the internal lubrication of the lubricant and the plasticizer can be regarded as the same kind of material, playing the role of plasticizing or softening. The difference is that the polarity of the lubricant is lower and the carbon chain is longer. Therefore, compared with plasticizers, lubricants and PVC are less compatible. Lubricants are incompatibly (and moderately compatible) with polyvinyl chloride, so only a small number of lubricant molecules can pass through the chains of the polymer like plasticizers, weakening their mutual attraction. When the polymer is deformed, the chains can slip and rotate more easily without lowering the glass temperature of the polymer too much.

2.External lubricant

External lubrication refers to the interface lubrication mechanism. The lubricant is attached on the surface of the molten resin or on the surface of the processing machine or mold, forming a layer of lubricant molecules. lubrication interface which is formed by the existence of molecular layer of lubricant, reduced the friction between the resin and the processing machinery as as result. The viscosity of the sliding interface film and its lubrication efficiency depend on the melting point and processing temperature of the lubricant. In general, lubricants with long molecular carbon chains play a better role of lubrication because they keep the two friction surfaces away from each other.

3.What will happen if PVC lubricant is not used well?

"Small dosage, large effect" . This sentence is an appropriate description of PVC lubricant. The function of PVC lubricant is no less than stabilizer in the role of PVC processing. Generally, its use  needs to follow strict principles, such as slippery balance inside and outside, right amount moderate etc. If the degree of significance of PVC lubricant is not enough, and we do not follow principles that should be observed, what will happen if PVC lubricant is not used well?

A.Imbalance of internal and external lubrication.

Too much external lubrication. The extrusion speed is fast, the material is easy to produce, and the plasticization is not good. Too much internal lubrication. There will be large extrusion and poor plasticization of materials. Poor initial lubrication will make the extrusion torque larger. Insufficient lubrication in the later stage will lead to insufficient lubrication in screw homogenization section, compression section and die section, violent shear of materials, which will affect the surface quality and internal performance of extruded products. More seriously, it even causes decomposition.

B.Excess lubricant.

C.Excess lubricant is not always better.

Lubricant is incompatible with PVC resin. Too much lubricant will have a bad effect on PVC blending system. Lubrication of internal and external balance, is balance within a certain limit because the mixing system of lubricant and PVC has bad effect. In the actual production, there are many processing problems related to thermal stability and many defects of the products. The root cause may be the excessive amount of lubricant.
