  • The error of construction welding net diameter should be controlled at 0.02 mm. For example, we buy wire diameter of 89 wire welding net, with a micrometer to measure the diameter, the diameter of the allowable range is 87 -91 wire. In this range is qualified welding net. Because the accuracy has been compared, but no one can control it so well in the production process. The welding net can be accurate to 0.01 mm, so the error is allowed.

  • After annealing, the wire will become soft, flexibility will increase, iron is a relatively active metal, and more active than hydrogen, so it is a good reducing agent. At room temperature, iron in the dry air is not easy to react with oxygen, sulfur, chlorine and other non-metallic elements, its production cost is lower, use and scale is wider, better protection function, so it is an important material for iron and steel parts in a strict working environment.

    hydroxypropyl methylcellulose. It is often added to lotions, creams, and shampoos to improve their texture and viscosity. HPMC is also used as a film-forming agent in some cosmetic products, helping to create a protective barrier on the skin or hair.
  • The production of redispersible polymer powders typically begins with the emulsion polymerization phase. In this stage, monomers, which are the building blocks of polymers, are mixed with water, initiators, stabilizers, and other additives in a reactor. The mixture is then heated to initiate the polymerization reaction, where the monomers combine to form long chains of polymers. This process is carefully controlled to ensure the desired molecular weight and particle size distribution of the resulting polymer latex.
