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.

Post time: 18-08-22Large coil galvanized wire is made of high quality low carbon steel wire rod processing, is made of high quality low carbon steel, after drawing molding, pickling rust removal, high temperature annealing, hot dip galvanized. Cooling process and other processing. Galvanized wire is divided into hot galvanized wire and cold galvanized wire. Galvanized wire in the process of smelting there are a lot of need to pay more attention to the place, galvanized wire products in the manufacturing process will experience a lot of process, of which the following galvanized wire annealing is a very important step, this step to the nature of galvanized wire has brought a lot of help.

- 6. The barbed rope protective net should be laid according to the terrain of the road boundary. The flat section should be set horizontally, and the slope section should be set along the slope or by the step form.
3, hexagonal network customized weight, the greater the weight, the more sufficient the material.
- In addition, the corrosion resistance of hot-dip galvanized wire will also be affected by other factors. For example, in different environments, especially in some special chemical environments, such as acidic or alkaline environments, the corrosion resistance of hot-dip galvanized wire may be affected to a certain extent. At this time, it may be necessary to use other materials that are more resistant to corrosion to replace the hot-dip galvanized wire.
- Packing: 25KG/ bale, plastic inside and woven outside.
The quality of hot-dip galvanized barbed wire is only in the surface of the wire attached to the galvanized layer, and with the reason of the chemical reaction, the surface of the zinc layer will gradually lose its role because of the oxidation reaction, this situation is more prominent in humid areas. And because after all, the steel wire will rust, so the quality of hot-dip galvanized barbed wire is certainly not up to the level of stainless steel barbed wire.

Pet cats are animals that people keep to relieve loneliness or for entertainment purposes. A pet cat is one of the more perfect animals: good-looking, independent, not dependent on its owner, giving more but taking less. The cat’s sensory organs are extremely well developed and always respond to its surroundings with keen sensitivity. Cats are very docile and have a rich body language to express their emotions. They purr when they are happy and pet you with their front PAWS. Some cats have a special habit of jumping on your lap to impress you. If a cat squats and gently wags its tail from side to side, it is an invitation to play. A twitch of the tail means it is angry.
Raw material of wire mesh sheet cold drawn low carbon steel wire base material can choose low carbon steel hot rolled disk bar or hot rolled smooth steel bar. The base material number and diameter of cold-drawn low carbon steel wire can be confirmed according to the rules in the table below. During the cold drawing process, the surface shrinkage rate of each drawing should not be greater than the wire mesh before cold drawing. Annealing shall not be carried out during wire drawing. If butt welding is required, the same production unit and base material of the same number should be selected. The appearance quality of wire mesh should not affect wire drawing. When the welding function is poor or brittle fracture occurs, special inspection should be carried out according to relevant standards.
- Now a lot of hardware manufacturers are producing iron wire, and the iron wire is very easy to rust, if you need to use in outdoor or humid places, the general customer will require the use of galvanized iron wire equipment to give the wire a layer of zinc, the thickness can be determined according to user requirements. Galvanized iron wire equipment is specially used for iron plating. Generally speaking, the stability of zinc is much higher than that of iron, and it will not rust in the daily water vapor or wet place.
Post time: 07-05-22- Hot dip galvanizing is in the hot melt zinc liquid dip plating, production speed, thick but uneven coating, the market allows the thickness of 45 microns, up to 300 microns above. It is dark in color, consumes more zinc metal, forms infiltration layer with base metal, and has good corrosion resistance. Hot dip galvanizing can be maintained for decades in outdoor environment. The protection of zinc coating on iron matrix has two principles: on the one hand, although zinc is more active and easy to oxidize than iron, but its oxide film is not as loose and compact as iron oxide. The dense oxide layer formed on the surface inhibits the further oxidation of zinc in the interior.
Hot dip galvanizing has been used for more than 150 years, and its principle has not changed so far. The steel structure should be fully immersed in zinc at one time to achieve uniform galvanized film structure. If it is too long or too wide to be dipped twice, the zinc layer at the joint will appear rough, too thick and so on. In addition, if the single weight of steel structure is too heavy, it will make its operation difficult if it exceeds the load of galvanizing equipment. Therefore, the communication with the hot dip galvanizing factory in advance.
2, hot plating wire plating after processing
Post time: 17-04-23- After the wire mesh appears black spots, you can choose the appearance of treatment to deal with this problem, such as galvanized, paint, dip plastic to deal with, after the appearance of the welding mesh surface smooth and bright, beautiful and generous.
