The large roll of galvanized wire is violently extinguished in oxygen and sparks radiate, while the sodium block and magnesium bar are extinguished in oxygen and no sparks radiate. This phenomenon is determined by the composition of large rolls of galvanized wire. The large rolls of galvanized wire used in the experiment are pig iron or steel wire, both of which are alloys of iron and carbon (complex substances containing the elements iron and carbon). When the carbon in galvanized wire is extinguished, carbon dioxide will be produced, and the solid will be changed into a gas, and the volume will shrink rapidly.
The life of the “wire”, is actually “low carbon steel wire”, carbon content in less than 0.2%. The surface is usually coated with zinc plating because it is easy to rust. Under atmospheric conditions, the galvanized layer will not rust before most of the fall off, relatively soft. The life of the “steel wire”, is carbon content in about 0.6% of the “carbon steel wire”, or carbon content in about 0.8% of the “high carbon steel wire”, they have enough hardness and elasticity after appropriate heat treatment, high strength. Uses such as winding ordinary spring and so on.
Galvanized wire coating rough, passivation film is not bright, bath temperature is too high. If the cathode current density is too high, zinc content in the bath is too high or sodium hydroxide and DPE content is too low; Solid particles or excessive foreign metal impurities in the electroplating solution can cause such problems. Solution: If the coating of large galvanized wire is rough, there may be solid particles in the plating solution. If the roughness of the part is severe, the current density may be too high.
Hexagonal mesh is also known as twisted mesh, insulation mesh, soft edge mesh. It is made of a single mesh reel. The mesh, mesh, galvanized and PVC coated properties are the same as the cage. This product can be different shapes, sizes of the stone into the alloy net to form a flexible whole, can be lifted, cars, shipping to the L place, the alloy net connected into a larger whole, the construction of throwing convenient, fast, good economic performance.
Hot wire mesh in the building wall engineering mainly played the anti-crack effect, inside and outside the use of specifications are not the same. Hot dipped wire material choose low carbon wire, through automation welding precision machinery processing after forming, surface treatment by zinc immersion process, galvanized barbed wire surface smooth and tidy, uniform structure strong, the overall performance is good, even if the local cutting or under pressure will not loose phenomenon occurs, it is the iron mesh strong anticorrosion performance in one of the widely used net class.
The shape of the cage has round, square, octagonal, hexagonal and other shapes. Because the circular space uses a large area, it is more suitable for the activities of birds, and it is not easy to get hurt, so it is popular with everyone. A cage is dear to a man who loves birds, for it is inhabited by his master’s birds. If well maintained, it can be maintained for many years. Let’s look at how to maintain the cage.
Blade barbed wire, also known as blade gill wire, blade gill net, is a new type of protective net. Blade thorn rope with beautiful, economical and practical, prevention effect is good, convenient construction, such as the excellent characteristics of plastic paint type razor wire is flake knife barbed wire rope after manufacturing, after rust protection processing and forming, the periphery of the razor wire should have very good anti-rust effect, peripheral processing should be good-looking, and can be a very good practical value, more convenient to install and Some advantages such as higher cost performance.
One is the frame isolation net, guardrail net with frame, frame using material cold plate belt welded into the square tube, usually 2*3 thickness 1.2 thick, the middle for low carbon steel wire welding mesh, wire diameter can choose another welding aperture can also choose, for example, customers want good quality long service time, you can choose thick wire diameter, small welding aperture, Such mesh is not only high quality, but also long service life, customized mesh and frame after welding, surface treatment to reach the customer needs of goods.
