perforated galvanized steel sheet

Dog cage mainly by welding, spraying, injection molding, surface treatment, electroplating dog cage is made of high quality steel wire, dog cages are with plastic and plastic surface treatment, electrophoresis, chrome plating, galvanized, imitation gold, etc., according to the customer request processing, respectively, also can be customized to sample, dog cage assembly of compact structure, neat and beautiful appearance, make folding and remove the cage is more convenient and quick, won’t take up too much space.

Copper sulfate point test is a simple way to quickly distinguish ordinary carbon steel and all types of stainless steel wire rope. The concentration of copper sulfate solution used is 5%-10%. Before the point test, the experimental area should be thoroughly removed from the oil or other impurities, and a small area should be polished by grinding machine or soft grinding cloth, and then the test liquid drops to the grinding place. Ordinary carbon steel or iron in a few seconds will form a layer of outer metal copper, and the surface of stainless steel does not produce copper precipitation or display copper color.

On the contrary, the denser the ion deposition, the better the quality of zinc layer. Under the condition that the surface zinc layer is dense and bright, the quality of zinc layer per unit area should reach 80g/m2, and the process parameters should be optimized as follows: current density is 16-20A /dm2, mass concentration of zinc sulfate solution is 500g/L, and pH value is 2.5-3.0.
