Proper technique is essential when using a granite drill bit
Because the coating obtained is thicker, hot-dip galvanizing has very good protective function than electric galvanizing, so it is an important maintenance coating for iron and steel parts in strict working environment. Hot-dip galvanized products are widely used in chemical equipment, petroleum processing, Marine exploration, metal structure, electric power transportation, shipbuilding and other occupations. In the field of agriculture, such as pesticide irrigation, greenhouse and construction industry such as water and gas transportation, wire casing, scaffolding, Bridges, highway guardrail and other aspects, it has been widely used in these years.
Hot-dip galvanized wire is widely used in chemical equipment, petroleum processing, Marine exploration, metal structure, electric power transmission, shipbuilding and other industries. It has been widely used in recent years in agricultural fields such as agricultural medicine sprinkler irrigation, greenhouse and construction industry such as water and gas transmission, wire casing, scaffolding, Bridges, highway guardrail and so on.
Cold galvanized is in the plating tank through the current unidirectional zinc gradually plated on the metal surface, production speed is slow, uniform coating, thin thickness, usually only 3-15 microns, bright appearance, poor corrosion resistance, generally a few months will rust. Compared with electrogalvanizing, hot galvanizing has lower production cost and less impact on the environment than electroplating.
Post time: 10-06-22The large roll of galvanized wire is like the literal meaning, is wrapped in a layer of zinc on the surface of low carbon steel wire material, beautify the appearance at the same time, but also improve the corrosion resistance of galvanized wire. Zinc dissolves easily in acids and also in bases, so it is called a bi-soluble metal. Zinc changes little in dry air. In moist air, a dense basic zinc carbonate film forms on the surface of zinc.
- Common galvanized iron wire equipment is usually used in the barbecue net, barbecue net generally requires to have a long service life, with galvanized iron wire equipment to the wire on a layer of zinc, barbecue net is not easy to be corroded.
- 2, galvanized wire mesh molding sheet storage ground should be flat, according to the symbolic requirements of the accumulation of regular, height should not exceed 2M, and away from heat sources, avoid exposure.
Barbed wire can be used to prevent livestock theft, for one thing, because the surface is covered with sharp spikes that make it difficult to get through the barbed wire. On the other hand, because livestock generally have the habit of collision, the use of barbed rope in the circle makes the livestock dare not rush to collision with the barbed rope, so as to save the user’s cost.
Post time: 06-09-222. The cleaning agent used for cleaning should have no effect on the binding force of the coating and no corrosion on the matrix.
- (3) Can realize butt joint, Angle joint, lap joint, T joint and other joint forms of welding.
- Common weight length conversion of barbed rope:
- Regular maintenance and maintenance, save a lot of time, but also save the cost of maintenance and maintenance. With good stability, corrosion resistance, greatly prolong the service life. There are many kinds, which can be selected according to different uses. The device for making annealed wire is simple, and the utilization rate of the device is improved.
- 3. The transport, storage and use of the binder of galvanized wire mesh should adopt safety and fire prevention methods according to the relevant regulations, so as to be safer.
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.
3, reduce the bivalent iron ion in the plating aid used for hot plating wire, reduce the formation of zinc slag
- 1, galvanized wire mesh molding sheet must be packed with flat hard data, to avoid eternal deformation due to poor packaging. It IS VERY IMPORTANT THAT EACH PACKAGE AND ROLL OF RAW SHEET MATERIAL BE MARKED WITH PRODUCT NAME, STANDARD, QUANTITY, TRADEMARK, batch number, MANUFACTURER, DATE of production, STACKING SYMBOL, INSPECTOR CODE AND INSPECTION CERTIFICATE.
- Similar to two materials in the coating part melting together, and coating thickness can reach 100 microns, so high corrosion resistance, salt spray test 96h no problem, equivalent to 10 years under the usual environment; Cold galvanizing is electroplating at room temperature. Although the thickness of the coating can also be controlled, the binding strength and thickness of the coating are relatively low, so the corrosion resistance is poor.
Post time: 30-09-22Galvanized iron wire is selected from excellent low carbon steel, through drawing forming, pickling rust removal, high temperature annealing, hot dip galvanized, cooling and other processes. Galvanized iron wire should pay attention to the following points in the use process:
- 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.
Now it is more used in the binding of the construction industry. Compared with ordinary wire, it is also softer and has better luster. Use in daily life does not need to carry out maintenance and maintenance, saving a lot of time, but also save the cost of maintenance and maintenance. Annealed wire has good stability, good corrosion resistance, greatly prolonging the service life. There are many kinds, which can be selected according to different uses. The device for making annealed wire is simple, and the utilization rate of the device is improved. The material properties of annealed wire can meet different processing needs.
- 3, galvanized silk mesh binder transport, storage and use should be in accordance with the relevant provisions to adopt safety, fire prevention methods, so as to be more safe use.
- 1) wire thickness: we also know that the pet cage wire is too thin to be easily bitten off by dogs, the general cage wire on the market are 3mm steel wire, such wire is only suitable for small dogs or rabbits, for large dog friends I suggest to buy more than 4mm thick.
- The cleaning agent used for cleaning has no effect on the adhesion of the coating and no corrosion on the base material. Acid activation Acid activation solution should be able to remove corrosion products and oxide film from the surface of parts without excessive corrosion of the matrix. Zinc plating may be zinc plated with zincate or chloride and appropriate additives shall be used to obtain a coating that meets the requirements of this standard. After light plating, light treatment is carried out. Passivated parts requiring hydrogen removal shall be passivated after hydrogen removal. Activation with 1% H2SO4 or 1% hydrochloric acid for 5 ~ 15s prior to passivation.
The difference is that hot dip galvanizing is dipped in zinc solution melted by heating, which has fast production speed and thick but uneven coating. 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. Cold galvanized is in the plating tank through the current unidirectional zinc gradually plated on the metal surface, the production speed is slow, uniform coating, thin thickness, usually only 3-15 microns, bright appearance, poor corrosion resistance, generally a few months will rust.
