The management system of the rinsing water after the steel wire pickling should be regularly and regularly discharged after the rinsing water, and the rinsing water should be kept clean and low acid value as far as possible. The pH control is more appropriate. The concentration of plating aid should not be too high. Hot plating wire must be added ammonium chloride and zinc chloride according to the data of laboratory analysis, and the specific gravity of the composite solution is controlled in the range of 50~80g/L. The addition of ammonium chloride or zinc chloride raw materials without the results of laboratory analysis shall be subject to criticism and education, and economic treatment if necessary.
- Although to be able to reduce the cost of production, but the overall strength of the product will have a great lack, so in this case will also let it have a great strength drop. Of course, in the mall, the higher the intensity of the data in the production of the higher the implementation of norms, naturally there will be certain progress in the price.
6, according to the wire diameter thickness to adjust zinc dipping time. Zinc dipping time should be adjusted according to the thickness of wire diameter. The method of adjustment is the length of the distance between the lead screw on the zinc pot and the ceramic sinking roll. The zinc dipping time of coarse wire diameter should be long, and the zinc dipping time of fine wire diameter should be short.
- For single-layer wound non-rotating wire rope, it is necessary to strictly abide by the above principles, otherwise it is easy to cause permanent deformation of wire rope structure; In the case of multilayer winding, the rotation of the rope is determined by the orientation of the reel’s rope groove to lay the foundation for the next layer. The friction between the wire rope and the extrusion pressure of the multi-layer winding drum are large, and the disorderly rope phenomenon is easy to occur. Therefore, the wire rope with a diameter slightly smaller than the pitch of the rope groove and the diameter of the rope groove should be selected to add the touch area between the wire rope and the drum.
Post time: 23-06-22In strict accordance with the multi-pass small compression rate drawing, the total compression rate is 96.48%, reducing the scraping of zinc layer. The whole wire drawing die is made of tungsten steel die and polycrystalline die. The Angle of the working cone of the wire drawing die is 12° ~ 16°, and the length of the sizing belt is 0.15 of the diameter of the wire, so as to ensure that the deformation of the zinc layer is basically synchronous with the steel wire substrate.
Zinc pot workers should be determined to do duty and responsibility. Do not leave the post without leave, always observe the change of hot plating wire galvanized layer, and according to the analysis results, master the asbestos block gap friction, how long it takes to press, replace the pressing face; Adjust the working face; Until all four faces of the asbestos block are used up, maintenance workers can continue to use the asbestos block after repair when necessary to reduce the consumption of asbestos block.
If the zinc coating is good, but in 3% nitric acid when the light, the coating has dark shadow, passivation occurs when the film is brown, may be caused by foreign metal impurities such as copper or lead in the galvanizing liquid. When problems occur in the process of galvanizing large coil galvanized wire, the temperature and current density are checked first, and then the content of zinc and sodium hydroxide in the plating solution is measured and adjusted through the analysis of the plating solution. Whether DPE content is low can be determined by hull cell test.
Annealing wire is widely used mainly because it has a good elasticity and flexibility, in the annealing process can be a good control of its hardness and softness, it is mainly made of iron wire, more commonly used in the construction industry tie wire use. When the wire factory is in production, the annealing wire will be processed according to the performance of the material, and its hardness will be changed according to the different demand, which can make it have more advantages, reduce the consumption of metal and reduce the cost of production.
Post time: 14-06-22No matter how old dogs are, they seem to love to touch noses with people and other animals. In fact, dogs touch noses as a way of socializing, just like humans shake hands and hug when they meet. But dogs don’t nuzzle every human or every animal. They pick and choose who to nuzzle. If they don’t like you, or don’t know you at all, they won’t touch your nose. However, adult dogs will touch almost every puppy’s nose, and they will not only touch the puppy’s nose, but also smell the puppy’s body.

Post time: 27-03-23When using these two products, it is obvious that there is a gap between them. By pulling or bending the wire, it is often difficult to restore the original, for example, if the same place is repeatedly bent, it will be found that it has broken, and the cold drawing wire will not. Cold drawing wire compared with iron wire, its hardness, tensile resistance, bending ability is greatly enhanced, suitable for building materials.
- 2.0*2.0mm 12 meters per kilogram
- Stainless steel barbed rope is in the material aspect of protection so durability is also better, these two products are known for long service life, but is high in price.
Now more and more people are buying the barbed rope, but there are often a lot of people do not know the specifications of the blade barbed rope when they buy, here is to introduce the specific characteristics of the blade barbed rope.
- Galvanized iron wire has good anti-corrosion and anti-rust ability, so it can be used in some outdoor guardrails or fences, especially on handicrafts, which are also of great use. Galvanized iron wire is not easy to rust and oxidation on the surface. 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.
- 4. When cleaning the cage, remember not to brush violently, but pay attention to the strength. Otherwise easy to damage the surface of the paint layer.
Post time: 16-12-22- In addition to these reasons, we should also pay attention to the tooling and process must be stable, and regular testing should be done to ensure the uniformity of galvanized layer.
- The service condition and service life of electro galvanized iron wire or component are closely related to the thickness of electroplated coating. The more strict the conditions of use and the longer the service life, the thicker the layer of galvanized iron wire required. Different products, according to the specific environment (temperature, humidity, rainfall, atmospheric composition, etc.) to determine the expected service life of the coating thickness, blind thickening will cause all kinds of waste. But if the thickness is insufficient, it will not reach the expected service life requirements. Different manufacturers, according to their own equipment conditions, in the case of determining the plating, the first preparation of a more complete and reasonable process flow, clear plating parameters, control plating solution concentration, standard operation.
- 4, after brushing, rinse with water. It should be noted that dogs like to lick everywhere. The disinfectant left on the fence is easy to be eaten by dogs, so be sure to flush several times. Finally, take the dog cage to the sun for 1 hour, ultraviolet radiation will make the sterilization effect double!
- Under normal circumstances, the organic matter contained in galvanized wire can make electroplating speed significantly reduced. Although chemical formulations facilitate high deposition rates, the deposition of organic matter does not meet the requirements of coating thickness, so activated carbon can be used to treat the bath.
Hook mesh we usually see everywhere, in fact, hook mesh is a kind of fence, like the highway, stadium fence, road fence, etc., have hook mesh. So what are the effects and advantages of the use of hook net? Next by xiaobian to introduce us to hook the characteristics of the net.
- Purpose of galvanized hexagonal net: building wall fixed, heat preservation, heat insulation
- Since nose touching is an important part of dogs’ social behavior, humans can use this to train them. Experts say that if owners touch their dogs’ noses often when they are young, they will grow up to have softer personalities and be far less likely to hurt people.
Bird cage placement and attention
