fine mesh for windows

There are many types of steel wire mesh that can achieve the effect of fencing, but there are not many options to take into account the cost. For this kind of light poultry fence, it is recommended to use Dutch steel wire mesh. Most users call it green steel wire mesh.

The diameter of cold-drawn wire should conform to the contract, check whether the amount of zinc meets the requirements of the contract, check the tensile strength, and ask the factory to provide the corresponding inspection report. The wire factory introduces that the weight of a single coil of wire of different specifications should not be lower than the volume weight required by the contract, and record the value. No contacts are generated for each reel of wire. If there are contacts, no more than three contacts are generated for each reel. Each contact should be smooth surface treatment, the wire can not be pulled off from the contact, in line with customer packaging requirements.

Cold galvanizing, also called electric galvanizing, is the use of electrolytic equipment to remove oil, pickling, after the pipe fitting into the composition of zinc salt solution, and connected to the negative electrode of the electrolytic equipment. Wire factory on the opposite side of the pipe fittings placed zinc plate, connected to the positive electrode of the electrolytic equipment is connected to the power supply, the use of current from the positive electrode to the negative electrode will deposit a layer of zinc on the pipe fittings, cold plating pipe fittings is first processed after galvanized.

Iron wire rust is a headache, not only the product performance decline, affect the use effect and life, and rust to human body and the environment also has a certain harm. Galvanized iron wire compared with ordinary iron wire more than a galvanized process, galvanized iron wire can rust?

Spray powder mainly acrylic powder, polyester powder and so on. Dipping is a kind of plastic coating process, that is, the plastic coating on the matrix, generally metal, such as: daily use of clothes hangers, pliers handles, scissors on the rubber sleeve, various handrails, etc. Plastic immersion is to heat the metal to spray plastic powder evenly on the metal to form a plastic film, or heat immersion liquid into the metal to cool it and then plastic coating on the metal surface.

Many electrogalvanized wire diameter products are formed by wire drawing, wire drawing is a kind of processing technology, can make the product reach the required shape and meet the standard mechanical properties. Cold wire drawing is carried out at recrystallization temperature, hot wire drawing is carried out at crystallization temperature, warm wire drawing is drawn at higher than room temperature and lower than crystallization temperature. Cold drawing is a common drawing method.

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 management system of the rinsing water after the steel wire pickling should be regularly and regularly discharged after the rinsing water, and the rinsing water should be kept clean and low acid value as far as possible. The pH control is more appropriate. The concentration of plating aid should not be too high. Hot plating wire must be added ammonium chloride and zinc chloride according to the data of laboratory analysis, and the specific gravity of the composite solution is controlled in the range of 50~80g/L. The addition of ammonium chloride or zinc chloride raw materials without the results of laboratory analysis shall be subject to criticism and education, and economic treatment if necessary.
