Currently, titanium dioxide as a food additive is classified as GRAS, or “generally recognized as safe.”
For example, Przewalskopeles is a first-class protected animal in China. At present, as long as there are several other przewalskopeles populations around Qinghai Lake in China, according to incomplete statistics, there are only about 1,000 of them left. Stainless steel barbed wire fence net is commonly used in grassland pastoral area of Qinghai Lake, with a height of 1.5 meters.
If the blade barbed rope produced by the barbed rope factory wants to be made into a straight line, it can’t be made too long because of the constraints of logistics.
In addition, heavy hexagonal net is commonly used in water conservancy projects, as the use of loading stone box, in order to achieve the purpose of river management, floods, in addition to it can also be used as slope prevention, retaining wall, breeding and cherish animals. Small hexagonal net is usually used for animal breeding, wall protection network, green vegetation network and so on.
What kind of wire mesh fence should be used for chickens, ducks, geese and other light poultry? The so-called good refers to the high cost performance, that is, the use effect can be achieved, such as the size of the mesh, the size, etc., and the cost can be reduced to the greatest extent.
The blade gill net of plastic paint is formed after rust protection processing after the manufacture of blade type barbed iron wire rope. The periphery of blade gill net should have good rust prevention effect, the peripheral processing should be beautiful, and can be of good practical value, more convenient installation, higher cost performance and other advantages. Plastic paint is a common electrostatic coating method, which can be fixed on the periphery of chicken wire or wire plate. After two hundred heat treatment, plastic paint or powder paint is glued to the surface of wire plate. These blade gill nets coated with plastic paint are generally used on indoor boxes. The coating processing does not take too long, mainly because the effect of rust prevention and corrosion protection is quite good, much better than the general material.
However, because the plating solution contains highly toxic cyanide, the gas escaping in the plating process is harmful to the health of workers, and the waste water must be treated strictly before discharge. Galvanized iron wire has good anti-corrosion and anti-rust ability, so it can be prevented from being used in some outdoor guardrail or fence, especially on handicrafts, handicrafts are also of great use, galvanized iron wire, the surface is not easy to rust and oxidation.
Cold plating is a physical treatment method, the zinc is simple and uneven, the amount of zinc is also less than in the corrosion and rust prevention and chemical disposal of hot plating; The amount of hot zinc plating is relatively thick, the surface of the disposal is flat on average, and it is not easy to fall off. A layer of alloy composed of zinc and metal has very strong oxidation ability, and there is a layer of pure zinc on the outside of this layer of alloy, which is why hot plating is thicker and stronger than cold plating. Under the condition of high degree of natural recovery, galvanized hook net can play a very good maintenance effect on the environment, it is not afraid of wind and rain, it is the battle machine in the hook net, much stronger than the dip plastic hook net.
In the atmosphere containing carbon dioxide and hydrogen sulfide and Marine atmosphere is not corrosion resistant, in high temperature and high humidity air and contain organic acid atmosphere is small, galvanized layer is also easy to be corroded. In order to make large rolls of galvanized wire on the surface of the deposited layer to the local, remove the surface film layer, surface inclusions and other defects can be found and treated by conventional techniques. Excess foam is caused by soaps and surfactant saponable fats brought into the tank, and moderate rates of foam formation may be harmless.
Steel wire and iron wire have many similarities, but carefully distinguish, will find that they are not only different in the material, but also in the product characteristics of the great difference. So when choosing, be sure to make a clear distinction between the two. Steel wire factory introduces steel wire carbon structural steel made above, generally not galvanized, used for machinery, spring. Black, very hard; Wire: made of mild steel (mild steel), galvanized, used for joining and binding. White and soft.
Galvanized wire can be seen as iron wrapped in carbon. When extinguished, the surface layer is more shallow than carbon can contact with oxygen, produce carbon dioxide gas, and radiate the iron wrapped in it. The more carbon galvanized wire contains, the more obvious the phenomenon of spark. The carbon wrapped in iron acts as if it were an explosive in a charge bag, occasionally blowing the iron apart. Sodium and magnesium contain few flammable impurities, and when extinguished, they just glow.
Pet cage from the use of material can be divided into plastic, wire, wire square tube, stainless steel four. General small animal cage multi-purpose is plastic and wire material, such as a lot of hamster cage, chinchilla cage are made of plastic or wire, small aquarium is plastic products, and the vast majority of small and medium-sized bird cage are wire products. The characteristics of this kind of small animal cage, is small, light, easy to carry, but also easy to clean care. For small animal cages, the wire diameter of the general iron wire is not very large, the thickness of the plastic is relatively thin, so the use of the time can not be “violent”, or the cage under the “destruction” will occur welding or plastic crack off.
The formation process of hot dip galvanized layer is between the iron matrix and the outside of the pure zinc layer, the formation of iron-zinc alloy process, the workpiece surface in hot dip plating when the formation of iron-zinc alloy layer, so that the iron and pure zinc layer is well combined. The process of large roll galvanized wire can be simply described as: when the iron workpiece is immersed in the molten zinc liquid, the first zinc and α-iron (body-centered) solid melt is formed on the interface. This is a crystal formed by the matrix metal iron dissolved with zinc atoms in the solid state. The two metal atoms are fused with each other, and the attraction between the atoms is relatively small.
Stainless STEEL HAS THE ABILITY to resist ATMOSPHERIC OXIDATION – that is, rust resistance, but also has the ability to resist corrosion in the medium containing acid, alkali, salt – corrosion resistance. However, the corrosion resistance of the steel varies with its chemical composition, additive state, service conditions and environmental media type.
Spring steel wire with high carbon quality carbon structural steel or carbon tool steel wire rod production, according to the use of spring strict control of its chemical composition, gas content and non-metallic inclusions. In order to reduce the appearance defect and decarbonization layer, the billet of consumption rod should stop the appearance grinding, and if necessary, stop the peeling.
