- Generally speaking, in dry main gas and indoor use, the thickness of galvanized coating is only 6-12μm, but under poor environmental conditions, the thickness of galvanized coating is 20μm, can reach 50μm. Therefore, environmental factors should be considered when choosing the thickness of galvanized layer. Galvanized layer after passivation treatment, can naturally form a layer of bright, beautiful color passivation film, can obviously improve its protective function, decorative.
The barbed wire factory will store the blade barbed wire inventory in the appropriate place, because it understands the product characteristics.
Post time: 17-02-23- Secondly, galvanizing can increase the mechanical strength of the product. The wire drawing process is to draw metal materials to make their grains thinner, thereby improving the mechanical strength of the product. Galvanizing can form a layer of zinc on the surface of the product, and the zinc layer itself has a high hardness, which can provide additional support during the wire drawing process and prevent the metal material from tensile fracture during the wire drawing process. Therefore, galvanized products after wire drawing can increase their strength and stiffness, and improve their tensile strength and torsional resistance.
- Pressure welded steel grid plate is the steel grid plate fixed by pressure resistance welding at each intersection of bearing flat steel and transverse bar, which is called pressure welded steel grid plate. Torsion torsion square steel is generally used for cross bar of pressure welded steel grid. Although they do not belong to the same variety, but in the steel lattice plate standards and performance are still the same.
In fact, iron wire has been widely used in our daily life, and it has very good performance. Iron wire production developed earlier because of its simple technology and wide application. Plastic spraying refers to the plastic powder, sprayed on the product of a surface treatment method. Plastic spraying is often referred to as electrostatic powder spraying, the use of electrostatic generator to make plastic powder charged, adsorbed on the surface of the iron plate, and then after 180 ~ 220℃ baking, so that the powder melt and adhere to the metal surface, plastic spraying products are used for indoor use of the box, paint film showing flat or matte effect.
The surface coating of galvanized wire can be seen whether the quality of galvanized wire is good or not. If the strength of zinc attached to the wire is very poor, then this galvanized wire do not buy, because this galvanized wire must be poor galvanized wire. High quality galvanized wire in general, the zinc layer attached to the surface of the wire is relatively thick, so when we buy galvanized wire, as long as we look at the thickness of the zinc layer, we can generally judge the quality of galvanized wire.
Post time: 16-03-23- 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.
- In this temperature range, the zinc solution is severely corroded to the workpiece and the zinc pot, and the iron is lost at 560 degrees Celsius to add obviously, and the zinc will be the iron substrate above 660 degrees Celsius, zinc slag will be added quickly, plating cannot be used. Therefore, electroplating is carried out in the range of 430~450 degrees Celsius.
- Because the barbed rope is a strong use of regeneration value. Generally, the use of discarded guardrail networks for exercise, or steel production of new structural raw materials, do a good job of daily cleaning up and recovery can promote the value of the whole guardrail network faster. Again is to recover the use, the use of it in the appearance of the use of places that are not high, such as as other days purse Seine; Taking apart or discarding the raw materials that do not need to rust can carry out the whole regeneration.
- Zinc layer thickness: hot dip galvanizing of electric welding mesh, single coating thickness is generally 0.08 ~ 0.12mm, and it is a controllable index.
The 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: 08-05-23- 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.
Did not do the adhesion test of powder spraying or fluorocarbon spray on the packaging galvanized wire, but there are two points for reference: one, in the sealed or air circulation environment, non-metallic volatiles can corrosion zinc coating; Second, zinc above 230 degrees (c) will brittle the base metal. After powder spraying and fluorocarbon spraying, it is necessary to bake at a higher temperature and in a sealed environment, causing rapid corrosion of zinc, resulting in loose corrosion film resulting in decreased adhesion of coating, and even leading to brittle situation of steel wire.
Post time: 11-04-23Even so, when they come out, they will uncover the mess, even though they know they will be punished, but only in a cage.) If you have time to refer to some foreign dog books, also strongly advocate cage training as a puppy. Before starting cage training, the cage is padded with a water bottle, some fun toys and bones to chew on. The cage door must be opened. Order the dog into the cage, then lure it into its new den with tasty cookies.
- Galvanizing can be done by zincate galvanizing or chloride galvanizing. Appropriate additives should be used to obtain a coating that meets the requirements of this standard. Light treatment should be carried out after light plating. The parts that need to be dehydrogenated for passivation should be passivated after dehydrogenation. Before passivation, 1%H2SO4 or 1% hydrochloric acid should be applied for activation for 5~15s. Passivation shall be treated with colored chromate unless otherwise specified in the design drawings.
But there are some necessary precautions in the production of galvanized wire. Remove all tools and piles on the work site and equipment that hinder activities, and slowly put the wire into the cylinder during pickling to prevent acid splashing on the body. When adding acid, the acid must be slowly poured into the water. Do not pour water into the acid to prevent acid spillage and injury. Workers should wear protective glasses when working. Then in the handling of wire and other items, it is strictly prohibited to push hard.
Wire mesh first welding after galvanized is through the end of welding and then the company to produce wire mesh wire mesh steel mesh construction mesh, floor heating mesh galvanized or hot dip galvanized. First galvanized after welding is to change wire mesh, after the end of welding can see the solder joint; The two processes are different in price. The cost of plating after welding is low, the appearance is smooth, and the cost of plating after welding is high, and it is not easy to rust.
To remove surface active substances by matting with activated carbon. Or filtration to make the foam less stable, which are effective measures; Other measures should also be taken to reduce the amount of surface-active substances brought in to Z. The electroplating speed can be significantly reduced by the introduction of organic matter. Although the chemical formula is conducive to a high deposition rate, the coating thickness cannot meet the requirements after the organic matter is loaded, so activated carbon can be used to treat the tank.
There are two varieties of steel grid plate is pressure welded steel grid plate and pressure lock steel grid plate, in many people’s eyes, these two products belong to the same variety, in fact, there are still great differences between them in many places.
Post time: 30-09-22Flood control and flood is good information. Can also be used for handicrafts manufacturing, machinery and equipment of transport network mountain beautification network – high strength wire grille (hook flower net, rhombus net) the use of mountain flowers network protection principle, hook flower net, mesh uniform, flat surface, weaving concise, crochet, beautiful generous, wire mesh, mesh with wider picture, diameter of thicker, not easy corrosion, taking a long, and strong usefulness.
Post time: 27-06-22- Hexagonal mesh is metal wire woven Angle mesh (hexagonal) made of barbed wire, the use of wire diameter is different according to the size of the hexagonal.
- In this temperature range, the zinc solution is severely corroded to the workpiece and the zinc pot, and the iron is lost at 560 degrees Celsius to add obviously, and the zinc will be the iron substrate above 660 degrees Celsius, zinc slag will be added quickly, plating cannot be used. Therefore, electroplating is carried out in the range of 430~450 degrees Celsius.
