Galvanized wire coating rough, passivation film is not bright, bath temperature is too high. If the cathode current density is too high, zinc content in the bath is too high or sodium hydroxide and DPE content is too low; Electroplating solution with solid particles or excessive foreign metal impurities, will lead to such problems. Solution: If the large roll galvanized wire to the above coating is rough, there may be solid particles in the plating solution. If the roughness of the part is severe, the current density may be too high.
When galvanized wire out of the light plating should be carried out light treatment. The bath temperature of galvanized wire should be controlled well. Galvanized wire, also known as hot dip zinc and hot dip galvanized, is an effective way of metal corrosion prevention, mainly used in various industries of metal structure facilities. It is to immerse the steel parts after rust removal into the molten zinc liquid at about 500℃, so that the surface of the steel member is attached with zinc layer, so as to play the purpose of anticorrosion.
When pickling, we should pay great attention to the acid has a strong corrosion, so when adding acid, we must pour acid into water, and it is along the wall of the cylinder, not a splash down, so as not to cause splash. Remember the order of pouring acid, acid into water rather than water into acid, water into acid will cause splashing and boiling, when pouring acid must wear protective glasses, must ensure that there are no non-professional onlookers, so as not to cause some risk of splashing acid.Many customers often ask: a kilogram of barbed rope to less than meters? How much does a barbed rope weigh in a meter? And so on the common problems, today Haorong screen manufacturers for everyone to answer.
Annealed wire is mainly through low carbon steel heating, hot drawing, constant temperature and other processes made into soft iron wire, because in the use of different, so there are different in the production process, made of a variety of specifications. Annealed wire can be widely used, mainly because annealed wire and other kinds of iron wire, has many advantages.
Now most people want to choose a few when choosing barbed wire material better thorn rope, but the special barbed wire the better, not right, it is important to choose which model is most suited to their own thorn rope,, although is very simple product, but in the use of these products are for specific situation is different, and has a different effect, Maybe now consumers do not have too much concept of blade barbed rope, in fact, such barbed rope products have a higher safety factor.
Hot wire plating adopts zinc-free slag to add hot molten zinc and galvanizing, which avoids the traditional heating process, radiates 1653 hot molten zinc on surface 4102 of zinc liquid surface, and reduces the high temperature oxidation of zinc liquid surface. At the same time, the heating body is in contact with the zinc liquid, and the heat is directly transferred to the zinc liquid. The utilization rate of heat energy can reach more than 90%, and the heat radiation on the zinc liquid surface is reduced.
The size of the dog cage is generally relatively small, suitable for indoor small dogs, dog cage is easy to carry, go out to compare the use, folding dog cage high strength steel wire and steel pipe material, the outer layer spray treatment. Strong texture, excellent rust resistance, the dog cage inside the tray, can be pulled out, convenient to clean the dog’s urine and feces, folding, dog cage is suitable for families and pet stores to raise more pet dogs.
1. Principle. Because zinc does not change easily in dry air, and in humid air, the surface can form a very dense film of zinc carbonate, which can effectively protect the interior from corrosion. And when the coating is damaged for some reason and the matrix is not too large, the zinc and steel matrix form a micro cell, so that the fastener matrix becomes the cathode and is protected. It is widely used in automobile transportation and other industries, but what is needed is the trivalent chromium passivation layer, zinc nickel alloy plating closed coating, reduce the harmful and toxic layer of hexavalent chromium passivation.
Galvanized hook net price is low: galvanized anti-rust cost is lower than the cost of other paint coating; Galvanized hook mesh durable: galvanized layer and steel is metallurgical combination, become a part of the steel surface, so the durability of the coating is more reliable; Galvanized hook net impact resistance: galvanized layer forms a special metallurgical structure, this structure can withstand mechanical damage in transport and use; Galvanized hook mesh quality is high: every part of the plated parts can be plated with zinc, even in the depression, sharp corners and hidden places can be fully protected.
