Cold galvanizing is also called electric galvanizing. It is the use of electrolytic equipment to remove oil, pickling, and then put the pipe into the solution of zinc salt, and connect the anode of the electrolytic equipment, place zinc plate on the opposite side of the pipe, and connect the positive pole of the electrolytic equipment to the power supply. A layer of zinc is deposited on the pipe fitting by directional movement of an electric current from the positive pole to the negative pole. Cold plated pipe fitting is processed before galvanizing.
Through the maintenance of galvanized wire, it can not only greatly prolong its service life, but also improve its efficiency in the daily use process. Because the labeled electrode potential of zinc is -0.762v, which is negative than iron, zinc becomes the anode when the galvanic cell is formed after being corroded by the medium. It itself is dissolved to protect the steel matrix. The duration of the protection of galvanized wire layer has a great relationship with the thickness.
The reason why there are black spots in wire mesh welding is that the action of wire feeding should be timely filled in the melting time, and the development should be appropriate. There is no argon gas, long burning, large current, long distance, blunt tungsten needle and high molten pool temperature are the fundamental reasons for blackening. Continuous burning, is about active welding machine energy selection, machine welding will appear black spots.
With the increasingly extensive use of hook mesh, the method of bridge rail is also different. The height of sidewalks or seatbelt outer railings should not be lower than 1.10 metres. The net distance between railings should not be greater than 140 mm and horizontal bar rails should not be used. The planning of the hook mesh is necessary to be safe and reliable, the bolt should be installed on the basis of the railing, its strength should meet the requirements of the standard.
- Suitable for general engineering building wall, pouring concrete, multi-storey building, etc., in the structure of heat preservation and heat insulation system plays an important role, when the construction will be hot dip galvanized welded wire rack together wall of heat preservation and heat insulation board placement will be concrete pouring mold inside, outside the wall heat preservation and heat insulation board and one kind of live, after ripping into heat preservation and heat insulation board and wall body. The coating on the surface of the welding core is called the coating.
Post time: 18-04-23Unless it is a specially customized model, the stainless steel blade barbed rope produced now is generally produced with a 22mm blade length mold, which is what we usually call bto-22 type. It doesn’t have to be the case that there are specifications from 11mm to 65mm. Unless the customer insists on customizing the specified length, the barbed rope manufacturer produces bto-22 stainless steel blade barbed rope.
For mountainous or hilly areas where the ground is more undulating set up stakes. You need to set a stake at the beginning and the end, and then determine the position. In the middle of the ups and downs, to increase the stakes according to the complexity of the ups and downs of the terrain, we need to be able to see 3 stakes at the same time, so that the installation is. It’s a straight line.
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; Solid particles or excessive foreign metal impurities in the electroplating solution can cause such problems. Solution: If the coating of large galvanized wire 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.
- In the corner area, the zinc layer is often thicker than other places, and has good toughness and abrasion resistance. And other coatings in this corner, often Z thin Z is not easy to construction, Z is easy to hurt, so often need to be maintained. Even if there’s a lot of mechanical damage or something. Causing a small layer of zinc to peel off, leaving the iron base exposed, the surrounding zinc layer will act as a sacrificial anode to protect the steel from erosion.
- The color of powder coating is divided into: blade blue, grass green, dark green, yellow. Spray blade gill net by hot-dip galvanized steel plate or stainless steel sheet stamping out sharp knife sheet, high tension galvanized steel wire or stainless steel wire as the core of the resistance device. Because the barbed wire shape is not easy to contact, so it can reach an excellent barrier effect. The primary raw material of the product is galvanized sheet, stainless steel plate, high quality low carbon steel wire (electric galvanized, hot galvanized, plastic coated, plastic sprayed) wire, blue, green, yellow and other colors.
Post time: 02-02-23One: according to the color of the spray blade thorn rope, its price is higher than the ordinary blade thorn rope 2000-2200 yuan, but the price ratio of the spray blade thorn rope is much higher.
It is best to use special columns to fix the barbed rope installation, because the standard column is not only beautiful shape and better protection effect.
- Another way is to have special equipment for measuring, which is expensive and impossible for ordinary users to buy. The last method is that there is a hierarchy gap in the light sense of the barbed rope, the general zinc barbed rope is more bright and the high zinc barbed rope is slightly darker, so customers do not think that the more beautiful the appearance of the product is good quality.
Post time: 26-07-22The 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.
Post time: 05-09-22- ① The diameter of galvanized iron wire for drawing shall not be less than 4mm, and the diameter of galvanized iron wire for binding shall not be less than 2.6mm.
- If the requirements are not high, and the ventilation is good, and relatively dry place, it is recommended to use electric galvanized barbed rope, because the price of this product has a certain advantage, for ordinary users, this is a more appropriate product.

Post time: 23-02-23The basic components of the bird cage are plate top, cage frame, cage bar, cage door, cage hook, dragon ring, bottom ring and cage bottom. The accessories are composed of dung board, sun rod, bird seed pot, water tank, jade finger, horsetail string, etc. These parts are usually made of wood or bamboo, and can be carved and hollowed out with a variety of laser machines.
Iron has gray iron, white iron and the above – mentioned combination of gold, each of which has different characteristics, so in industry, according to their different characteristics to transport and selection. For example, in gray iron, its carbon exists in iron ore as graphite, and the crack is often gray, soft and tough, simple filter cutting, which is suitable for casting.
- Zinc dipping time should be adjusted according to the thickness of wire diameter. The method of adjustment is to use the lead screw above the zinc pot, the length of the distance to the ceramic sinking roller. Thick wire diameter zinc dipping time should be long, fine wire diameter zinc dipping time should be short, zinc dipping length is in the range of 2~3.5m, which is also to reduce the zinc consumption of steel wire, is an aspect of maintaining the uniformity of zinc layer.
Post time: 09-11-22Aquaculture galvanized welding net this mesh structure is easy to construction, to ensure quality. Compared with the traditional manual binding on site, it can guarantee the quality of the project, shorten the anti-drug construction and shorten the construction period. So now such grids are being used in new villages to strengthen walls and prevent earthquakes.
- The application range of small hexagonal net is also relatively wide, can be used for building wall fixed insulation layer, pipeline, boiler fixed insulation, decoration and other fields.
- 2. Breeding chickens, ducks, geese and other small animals, fruit and wood garden enclosure protection, medium breeding protection, it is recommended that you choose 2.3mm-2.5mm wire diameter products.
The galvanized layer forms a particular metallurgical structure that is capable of accepting mechanical damage during transport and use. Every part of the plating can be zinc plated, even in dents, sharp corners and hidden places can be fully maintained. The galvanizing process is more convenient than other coating construction methods, and can avoid the required time after the installation on the site.
- 3. Before cleaning the cage, put the birds in a safe place, and then clean out the garbage inside the cage. Clean it up with a sweep. Then use a wet rag to clean on site.
