3. Gypsum Gypsum is another common ingredient in mineral fiber ceiling tiles. It is a naturally occurring mineral that can improve the fire resistance of the tiles. Gypsum boards are often used as a backing for mineral fiber tiles, contributing to their overall stability and performance.

With the development of mining industry, the classification of pig iron is already very broad in our country, which can satisfy the demand of mechanical industry. In general, the iron used to produce large rolls of galvanized wire can be divided into two classes. A metal exercised directly from the iron ore through the iron making stroke, the composition of the ore is iron oxide, silica and other miscellaneous stones. When this ore is specially refined into metal iron, carbon, silicon, manganese, and other elements are mixed into it. The material produced in this way is called ordinary pig iron, which is also the material for the first grade.

Cold wire drawing is a kind of cold processing of metal. The raw material is wire rod, which is produced by peeling, galvanizing and other processes. Galvanized cold drawing is used more in building materials. Its testing standards are also different. The strength of cold drawing is relatively high. Because of the high strength of steel, it plays a very important role in construction. It saves the construction steel in building materials, and also reduces the cost of the project. It also plays a very important role in the structure of concrete.

Different from the general zinc barbed rope, the zinc content of the surface of the high zinc barbed rope is very high, which can reach 6-8 times of the former, so that it has a great advantage in service life. Ordinary products begin to corrosion in three or five years, while the latter takes longer time to change. Stainless steel barbed rope is in the material aspect of protection so durability is also better, these two products are known for long service life, but is high in price.

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.
- Production technology: Through the excellent low carbon steel rod drawing forming, pickling rust removal, high temperature annealing, hot dip galvanizing. Cooling and other 5 operation processes refined. Galvanized wire characteristics: good resistance and elasticity, strong corrosion resistance.

B. When the thickness of the plating is greater than 4 mm, the zinc adhesion should not be less than 610g/m, that is, the average thickness of the zinc layer should not be less than 86 microns.

Wire mesh is the iron screen with high corrosion resistance, the same is also one of the iron net class of widely used net class, its efficient corrosion resistance function in breeding industry, construction industry and other aspects are much liked. Its smooth and neat net surface, not only increased their aesthetic feeling, but also can play a certain decoration effect.
- (6) Save transportation costs. It can be reduced into small rolls, and involved in moisture-proof paper packaging, occupying little space.

Stainless steel barbed rope in the way of corrosion is not very, because the surface is not treated but rely on its own raw materials for corrosion resistance, so there will be no chemical reaction. After a long time of use, it will not rust like the corrosion layer on the surface of hot dip galvanized barbed rope, because the internal material of stainless steel barbed rope is the same as the material on the surface. The most obvious difference in a short time is the cross section of this piece, hot dip galvanized barbed wire because of surface anticorrosion treatment, so there will be rust in the cross section of this piece, and stainless steel barbed wire because the internal raw materials and surface raw materials are consistent, so there is no such situation.

- Galvanized hexagonal net is a kind of galvanized metal wire mesh, mesh shape is hexagonal.

Cold wire drawing is a kind of cold processing of metal, that is, we often say reinforcement. Cold drawing process is not messy, cold drawing price based on the quality of cold drawing dividends of different levels, cold drawing production is also a variety of different procedures. The main factor affecting the strength of cold drawing wire is raw materials, which are closely related to the raw materials, strength and diameter of raw materials, and the better the quality of cold drawing wire, the more messy the production process.

Our country industry chooses the low carbon steel with good quality as raw material, and then produces the quality galvanized iron wire by drawing, galvanizing and other processes. Now the production technology of galvanized iron wire products can be divided into hot plating and electroplating two kinds of methods. No matter which one is chosen, it should be carried out in accordance with the corresponding operating specifications, so as to better ensure the production of good products. For key and important parts with tensile strength greater than 1034mpa before plating, the stress should be released at 200±10℃ for more than 1 hour and 140±10℃ before plating.

Post time: 12-06-24 - Galvanizing can be done by zincate galvanizing or chloride galvanizing. Appropriate additives shall be used to obtain a coating that meets the requirements of this standard. Luminescence treatment should be carried out after luminescence 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 to activate 5~15s. Passivation shall be treated with colored chromate unless otherwise specified in the design drawings.
- Pay attention to the maintenance of the dog cage, plastic and wire and other materials of the dog cage need to avoid exposure to the sun, the dog cage must be cleaned in time after cleaning with water, or rust will affect the service life.

Post time: 16-06-22 - Because they are afraid of the rain, so there is no need to say more, and the surface of the packaging is more afraid of the sun, so it is not recommended to prevent the outdoor blade thorn rope will cause the woven bag to become ineffective, resulting in the internal blade thorn rope exposed to affect the later use.

Large hexagonal mesh called stone cage net, is mainly used for mountain protection, hydraulic construction and so on. Small wire hexagonal mesh is used as a good material for breeding, will twist twist hexagonal mesh in the welded iron frame on the hexagonal mesh welding into chicken coop, pigeon cage, rabbit cage cage cage, hexagonal mesh is the best material for breeding with a net.
- The production and processing process of the blade thorn rope is complicated, which requires the cooperation of all departments, and the production cycle is relatively long. Whether galvanized rope or stainless steel rope, because of the relatively simple structure, the degree of mechanization in the production process is relatively high, so it is also a relatively big difference in price.
