If 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.

The basic thing to choose a pet carrier is to be able to stand up straight inside it, so that your pet can be comfortable, but also need to be able to stretch out all four feet when lying down. Think of your pet as a person, and give it a larger cage where it can move around on one side and sleep on the other. You can use an old blanket for cushions in your pet’s cage, or buy special cushions for pets, as long as they are comfortable.

Electric galvanized wire direct selling is in the plating tank through the current one-way to gradually zinc plating on the metal appearance, the 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 hot dip galvanizing, the production cost of electric galvanizing is lower. The difference between cold galvanizing and hot galvanizing: the difference between cold galvanizing and hot galvanizing is that the amount of zinc is different. They can be identified from the color. The color of cold galvanizing is shiny silver white with yellow. Hot dip galvanizing shiny white.

Hot wire mesh in the building wall engineering mainly played the anti-crack effect, inside and outside the use of specifications are not the same. Hot dipped wire material choose low carbon wire, through automation welding precision machinery processing after forming, surface treatment by zinc immersion process, galvanized barbed wire surface smooth and tidy, uniform structure strong, the overall performance is good, even if the local cutting or under pressure will not loose phenomenon occurs, it is the iron mesh strong anticorrosion performance in one of the widely used net class.

To many people, a dog cage looks like a prison, but for dogs who have been raised on cage training, it is their home and shelter. A cage should be a comfortable place. Never put a dog in a cage for no reason. They will see it as punishment. (Why do many dogs fail to adapt to their owners’ commands, because whether the paparazzi can come out or not, it is also seen as a punishment.

Some customers are more concerned about quality problems, so for the service life is more important, barbed rope factory will generally recommend the use of high zinc barbed rope or stainless steel barbed rope.

Traditional wire mesh is crisscross woven into the wire, with the development of the economy, the rapid rise of all walks of life, the use of traditional wire mesh limitations gradually exposed, such as: aquaculture, to the chicken circle a cage can not be too dense, the wire can not be too thick, woven up the net wire once the mesh is too large net surface will become soft.
