For example, we buy wire diameter of 89 wire welding net, with a micrometer to measure the diameter, the diameter of the allowable range is 87 -91 wire. In this range is qualified welding net. Because the accuracy has been compared, but no one can control it so well in the production process. The welding net can be accurate to 0.01 mm, so the error is allowed.
Poor pretreatment before electroplating; Bath temperature is too low; Poor quality additives or excessive additives and organic impurities can cause poor bonding. The quality of the additive also has an effect on coating foaming. Some additives react incompletely during synthesis and continue to polymerize during long-term storage or use. The additive tends to distort the lattice and create stress, causing the coating to blister.
1, want to a person or friends together, leave the dog a person at home, so that it will not be hurt, the dog is comfortable, safe, but not because of loose and develop bad habits, at this time you can use the pet cage.
Stainless steel material refers to air, steam, water and other weak corrosive medium and acid, alkali, salt and other chemical corrosive medium corrosion of steel, also known as stainless acid-resistant steel. In practical application, the steel that is resistant to weak corrosive medium is often called stainless steel, and the steel that is resistant to chemical medium corrosion is called acid resistant steel. And galvanized wire has good toughness and elasticity, the amount of zinc can reach 300 grams/square meter. It has the characteristics of thick galvanized layer and strong corrosion resistance. Products are widely used in construction, handicrafts, silk mesh, highway fence, product packaging and daily civilian and other fields.
Pet cage has many types, and selective is bigger, pet cages are generally made of wire, with better coarse, then at the bottom with a wheel base, such a simple pet basket was made, in the wheel at the bottom of the mount is for the convenience of the mobile, a pet cages should also adapt to the location of the production in addition to a door, It is convenient for feeding pets.
Its wire diameter specifications include: 8#-24#, with thick coating, corrosion resistance, strong coating and so on. And according to the special needs of users, according to industry standards to provide various specifications of galvanized wire. Low carbon steel wire is called galvanized iron wire after drawing and galvanized, so galvanized wire products have certain characteristics. In order to better let galvanized wire play an effect, in the process of galvanized wire, generally according to customer needs to control the thickness of galvanized wire zinc layer, so that galvanized wire can meet the needs of customers.
The insulation layer of large rolls of galvanized wire and rigid thermal insulation products can be bound with double strands of galvanized iron wire, and the binding interval shall not exceed 400mm. The pipe or corresponding equipment with nominal diameter equal to or greater than 600mm shall stop reinforcement after binding, and the enclosed galvanized steel wire must be winched. The iron or wood rod should be tightened, but the tightening level should be moderate, not too tight or too loose, and not damage the wire. The consumption of wire and steel wire is generally used in drawing process and galvanized disposal.
If not packaged, then a car of blade thorn rope can not be loaded with many pieces, but also relatively occupied places and easy to be lost in the process of transportation. Each bundle of blade barbed rope is 50 bundles. After hydraulic compression, the volume is reduced and it is more convenient to load and unload. Forklift trucks can load and unload easily. In general, when exporting, the blade thorn rope will be packaged for sale, so that the volume occupied in the container is relatively small, which can be very easy to size and place will not take up much place.
According to the different technology is divided into different types, you can choose according to your own needs. Has good flexibility and elasticity, the main role of annealing wire is to control its degree of softness and hardness, when the annealing wire is made of steel wire, now more used in the construction industry bundle use, compared with ordinary iron wire is also softer, has a better luster.
Bird cage to keep clean, bird cage is the birds often live and activity place, so the bird cage should not only have a place to put water and food, but also need to be cleaned regularly to the bird cage, so as to reduce the parasite.
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.
Hot dip galvanizing is dipped in zinc liquid melted by heating, with fast production speed and thick but uneven coating. The market allows a low thickness of 45 microns and a high of more than 300 microns. The color is dark, the consumption of zinc metal is much, the formation of infiltration layer with the matrix metal, the corrosion resistance is good, and the outdoor environment of hot dip galvanized can be maintained for decades. Application range of hot dip galvanizing: because the coating is thicker, hot dip galvanizing has better protective performance than electric galvanizing, so it is an important protective coating for iron and steel parts in harsh working environment.
