Cold galvanizing (galvanizing) is in the plating tank after the current unidirectional, so that the zinc gradually plated on the metal surface, slow production speed, uniform coating, thin thickness, usually as long as 3-15g, bright appearance, poor corrosion resistance, usually a few months will rust. Compared with hot dip galvanizing, the production cost of electric galvanizing is lower.
Hot dip galvanizing is a kind of external treatment technology in the production of fasteners. The common varieties of hot dip galvanizing fasteners are electric galvanizing, powder galvanizing, mechanical galvanizing and hot dip galvanizing. Wire factory according to different requirements of customers for fasteners, different hot-dip galvanized surface treatment. Galvanized layer and steel is a metallurgical connection, become a part of the steel surface, so the durability of the coating is more reliable.
Cold galvanized, generally speaking, do not need heating, galvanized amount is little, this galvanized parts are easy to fall off in wet environment. Hot dip galvanizing, also known as hot dip galvanizing, is to melt the zinc ingot at high temperature, put some auxiliary materials in, and then dip the metal structural parts into the galvanized groove, so that the metal members are attached to a layer of zinc layer. The advantage of hot dip galvanized is that its anticorrosion ability is strong, the adhesion and hardness of galvanized layer is better.
Plastic spraying is also we often talk about electrostatic powder spraying, it is the use of electrostatic generator to make plastic powder charged, adsorption on the surface of the iron plate, and then through 180~220 DEG C baking, so that the powder melting adhesion on the metal surface, plastic spraying products are used for indoor use of the box, paint film flat or matte effect. Spray powder mainly acrylic powder, polyester powder, etc.
Titanium and titanium alloy with light weight, high strength, corrosion resistance and many other characteristics, titanium and its alloy not only in aviation, aerospace industry has a very important application, and has begun to chemical, petroleum, light industry, power generation, metallurgy and many other civil industrial sectors are widely used. However, titanium and titanium alloy are smaller than steel in terms of hardness and strength. The shortcomings of titanium alloy wire made of titanium alloy in terms of hardness limit its breadth and depth of application.
The quality of hot-dip galvanized barbed wire is only in the surface of the wire attached to the galvanized layer, and with the reason of the chemical reaction, the surface of the zinc layer will gradually lose its role because of the oxidation reaction, this situation is more prominent in humid areas. And because after all, the steel wire will rust, so the quality of hot-dip galvanized barbed wire is certainly not up to the level of stainless steel barbed wire.
The use of welding network is very wide, but also used in different industries, different places, many times the name is because of the use or use of the name, so the various uses of the welding network, destined to name a variety of different. Can be called row welding net, or zinc plating welding net or galvanized welding net. And then there’s the external insulation wire, just for insulation, usually on the outside of the wall, to reduce heat loss.
1, galvanized silk mesh molding sheet must be packed with flat hard materials, to avoid improper packaging and cause eternal deformation. It is important that each package and roll of raw material be marked with product name, standard, quantity, trademark, lot number, manufacturer, date of production, packing symbol, inspector code and inspection certificate.
Dogs of all ages seem to love to touch their noses with humans and other animals. In fact, dogs touch their noses as a way of socializing, just like humans shake hands and hug when they meet. But dogs don’t touch every human or every animal. They pick and choose who to touch. 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 it.
1. Grid structure is simple, beautiful and practical; 2. Easy to transport, installation is not limited by terrain relief; 3. Especially for mountain, slope, multi-curved area adaptability; 4. Medium low price, suitable for large area use. Main market: railway, highway closed net, yard fence, residential guardrail, all kinds of isolation net.
1. The surface of the stainless steel pet cage is deposited with dust or alien metal particles containing other metal elements. In the humid air, the condensed water between the attachment and stainless steel will connect the two into a micro cell, which causes the electrochemical reaction and the protective film is destroyed, which is called electrochemical corrosion. To avoid this situation, as long as the stainless steel surface is clean, you can ensure that the stainless steel pet cage does not rust.
This oxide film has greater elasticity and lubricity, does not affect the accuracy of parts. Therefore, the parts of precision instruments and optical instruments, spring steel, thin steel sheet, fine steel wire and so on are commonly bluing treatment. The commonly used galvanizing treatment of large roll galvanized wire is equivalent to forming a protective layer on the surface of the iron wire. The commonly used methods are hot dip galvanizing, hot spray plating, vacuum plating and so on. Different methods have corresponding characteristics.
