Common sheet sizes for FRP grating include: 4’x8′, 4’x12′, and 3’x10′. Common thicknesses include: 1″, 1.5″ and 2″
There is no adhesion test of powder spraying or fluorocarbon spraying on packaged galvanized wire, but there are two points for reference: first, in sealed or air-free environment, non-metallic volatiles can corrode zinc coating; Second, zinc at higher than 230 degrees (c) will cause the matrix metal brittle. And powder spraying and fluorocarbon spraying are to be baked at a higher temperature and in a sealed environment, causing rapid corrosion of zinc, resulting in loose corrosion film resulting in coating adhesion decline, and even lead to (matrix) steel wire brittle situation may exist.
Some customers may not immediately use the blade barbed rope when they buy it for retail and some are temporarily not used for site construction. At this time, customers need to follow up the characteristics of the blade barbed rope for storage. Because they are afraid of the rain, so there is no need to say more, and the surface of the packaging is more afraid of the sun, so it is not recommended to prevent the outside of the blade thorn rope will lead to the woven bag become lost effect, resulting in the exposure of the internal blade thorn rope affect the later use.
Cold drawing wire is a metal cold processing, with wire rod as raw material, that is, the mouth of the steel bar. Cold drawing wire is a product produced by a series of processes such as shell stripping, which is a common wire. In the development and production of metal materials, cold drawing wire is a very common material, its performance is good, the range of use is very wide, manufacturers in processing are the use of cold processing to produce.
The technical term “galvanized” means that metal has been specially treated with zinc. Essentially, the wire is covered with a very thin layer of zinc. It is this thin layer of zinc that gives galvanized wire its many properties. Galvanizing can be done by dipping wire into a pool of zinc or by electroplating. Are you familiar with galvanized wire mesh? Do you know what to pay attention to in the process of use?
Stainless steel barbed rope in the way of corrosion is not very, because the surface is not treated but rely on its own raw materials for corrosion resistance, so there will be no chemical reaction.
The lighting surface of each type of shed is designed to be curved, improving the Angle of the light surface, because the lighting surface is curved, no dust accumulation, good light transmittance, high temperature in the shed, after measurement, the average temperature in the shed is 3℃ higher than the traditional bamboo pole cement column shed, the yield is increased by 15~20%, and the harvest date is advanced. The formula is scientific, the surface does not absorb moisture, do not return halogen through modification technology and scientific production process, solve the greenhouse frame rod is easy to absorb moisture return halogen, poor water resistance and easy to change the shortcomings, so that the greenhouse steel pipe in the high temperature and high humidity environment, few drops, frost phenomenon, and reduce pests and diseases.
Galvanized iron wire is very common in practical application, some people think that galvanized iron wire will not rust, in fact, it is not. Metal corrosion is caused by the chemical or electrochemical action of the surrounding medium. According to different media, it is divided into atmospheric corrosion, soil corrosion, seawater corrosion, bacterial corrosion and so on. Atmospheric corrosion is more common, because metal products in the process of processing, transportation and storage, when in contact with the atmosphere, there are always atmospheric corrosion conditions.
Compared with other galvanizing processes, galvanized steel wire has low cleaning requirements before plating. However, under the current trend of increasing the quality level of galvanized layer, some pollutants brought into the plating tank are obviously harmful. Because cleaning galvanized coating wastes a lot of time and reduces production, it is very important to properly clean and effectively rinse the substrate before electroplating.
The large roll of galvanized silk should be coated with oil, the fiber core is dipped in oil, and the grease should be able to protect the fiber core from decay and corrosion, the iron wire moistens the fiber, and lubricates the wire rope from the inside. The surface is coated with oil so that all the wire surface in the rope strand is evenly coated with a layer of anti-rust lubricating grease, which is used for the mine rope with friction lifting and mineral water, to be coated with black grease with increased wear and strong water resistance. Other uses are coated with red oil oil with strong film and good rust resistance, and require it to have a thin oil layer, which is easy to keep clean during the operation.
Wet air in rain and snow climate, steel mesh sheet exposed, easy to rust, to avoid affecting the use of steel mesh, it is necessary to carry out simple rust prevention treatment, of course, slight rust float will not affect the use of steel mesh. Common network site storage, rainy days, heavy snow, rainy days and rainy days, how to better save the steel mesh, this is a lot of friends need to consider.
Cold galvanized is in the plating tank through the current unidirectional zinc gradually plated on the metal surface, production speed is slow, uniform coating, thin thickness, usually only 3-15 microns, bright appearance, poor corrosion resistance, generally a few months will rust. Compared with electrogalvanizing, hot galvanizing has lower production cost and less impact on the environment than electroplating.
When using these two products, it is obvious that there is a gap between them. By pulling or bending the wire, it is often difficult to restore the original, for example, if the same place is repeatedly bent, it will be found that it has broken, and the cold drawing wire will not. Cold drawing wire compared with iron wire, its hardness, tensile resistance, bending ability is greatly enhanced, suitable for building materials.
