aluminum window screen frame materialIf the zinc coating is good, but when the light comes out in 3% nitric acid, there is a dark shadow on the coating, and the film is brown when passivation occurs, which may be caused by foreign metal impurities such as copper or lead in the galvanized liquid. When there is a problem in the process of galvanizing, check the temperature and current density first, and then measure and adjust the content of zinc and sodium hydroxide in the bath through the analysis of the bath. Whether DPE levels are low can be determined by Hull cell test.

aluminum window screen frame materialThe corrosion or discoloration of galvanized iron wire in the atmosphere caused by oxygen, moisture and other pollution impurities is called rust or rust. After galvanized iron wire rusting, it will affect the appearance quality, seriously affect the use, and even cause scrap, so galvanized iron wire must be properly kept and pay attention to rust prevention.

We must have a certain understanding of the hexagonal network, we are the beautiful appearance of the hexagonal network, hexagonal network is not only very beautiful appearance, in fact, the practical value of survival is very high. To introduce the relevant information should be very clearly know the highway guardrail net, hexagonal wire netting in all kinds of fence netting, in the value of the high-speed on the road more MaoJian, it not only be used in all kinds of road, in a sports ball games venue and try our best to take care of landslides, also has reached very matter effectiveness.
When laying steel wire mesh, according to the laying method from the middle to both sides in turn. Wall plastering engineering use wire mesh material is generally two kinds: one is electroplating, the other is hot dip galvanized. The former has low cost and a wide range of use. The cost of hot-dip galvanized material is slightly higher than that of electroplating, and the cost is high and the life is good to prevent rust. Hot dip galvanizing is in the case of heating plating. After the zinc is melted into liquid form, the base metal is immersed in it so that the zinc interpenetrates with the base metal and binds so tightly that there are no other impurities or defects left in the process.
Most people in addition to pay attention to the price of barbed rope, many people for hot-dip galvanized barbed rope or cold galvanized barbed rope will have questions, in fact, these two products, the price difference is not very big, so how to choose hot-dip galvanized barbed rope and electric galvanized barbed rope?

Performance characteristics of zinc coating: zinc layer of thick galvanized wire zinc layer crystallinity meticulous, uniform and no gap, good corrosion resistance; The zinc layer obtained by electrogalvanizing is very pure and corrodes slowly in the gas, liquid and fog of acid and alkali, which can effectively protect the steel matrix. Galvanized layer can also be chromic acid passivation treatment into a variety of colors, beautiful and generous, with good decorative; The zinc layer on the galvanized wire has good ductility, can be cold blanking, rolling, bending and other molding without damage to the zinc layer.
