Temporary rust prevention is to prepare for the completion of the mission of the protective layer to be removed. The methods include: cajoling corrosion inhibitors, coating antirust oil, peeling molecular compound plastics, drying air, vacuuming, etc. Change the internal structure of the metal: new chromium, nickel and other alloy elements made of stainless steel, but the alloy is not much, expensive, difficult to produce widespread application.
On the highway, barbed rope protection net is generally to prevent people and animals from crossing the highway at will, so as not to interfere with driving and reduce accidents, as well as effectively prevent illegal occupation of road land and other issues of traffic safety facilities. There are many forms of barbed rope protective nets, commonly used metal, woven net, barbed wire and often green gracilaria. Metal braided net is set in crowded areas, barbed wire is used in areas with few people and animals, and the structure of hedges and barbed wire is used in toll stations and service areas. In the past two years, considering the beauty of the problem, in the Pearl River Delta region of some highways with fruit plastic spot welding network (usually said guardrail network), this barbed rope protection network is more good-looking, durable, the overall effect is good, but the construction requirements are higher, more expensive. General sections should not be used, in the city center, scenic spots or strong requirements for beautiful sections can be used.
The application of barbed rope is calculated in accordance with the length, but the purchase of barbed rope is calculated in accordance with the weight of the barbed rope, which causes the user is difficult to count the number of procurement confusion, so we need to understand clearly, a kilogram of barbed rope to less meters? How much does a meter of barbed rope weigh? These two problems, the procurement of thorn rope becomes very simple.
Steel mesh jinsu appearance treatment: polyethylene thermoplastic powder coatings is also called polyethylene powder coating, is the high pressure polyethylene (LDPE) as the basic material, adding a variety of function additives, colors, its antiseptic powder coating manufacturing processes, jinsu coating layer has the function of chemical, shock, circuitous, acid, salt fog corrosion, decorate a function and has good appearance.
Hot dip galvanized welding mesh is made of iron wire, processed by precision automatic mechanical technology. The mesh surface is smooth, the structure is strong, and the integrity is strong. Even if the local cutting or local pressure is not relaxed, the hot dip zinc is processed. Hot dip galvanized welding mesh surface white color, thick zinc layer, high zinc content at the solder joint, uniform mesh, flat mesh surface, solder joint tensile resistance, high corrosion resistance. It has the advantages that ordinary barbed wire does not have.
Galvanized wire A stable layer of zinc is coated on the outside of the wire, which is used to protect the wire and make the wire service life longer. When producing galvanized wire, the wire is pickled. Pickling is to use some acid mist or acid to wash off some oxides on the surface of iron, that is, rust, and some other corrosive substances, to achieve the purpose of cleaning iron, so that zinc will fall off when galvanizing.
Hexagonal guardrail net custom corrosion lost the original characteristics, in the shape, color and mechanical properties will change, resulting in equipment damage, pipeline leakage, etc., specifically, is prone to fracture, lose the original protection function. Usually there are three kinds of metal corrosion: physical corrosion, chemical corrosion, electrochemical corrosion, corrosion in addition to the chemical properties and organizational structure of the metal itself, but also related to the surrounding medium, such as wet environment than dry environment easy corrosion, more impurities than impurities less easy corrosion, high temperature conditions than low temperature conditions easy corrosion. After understanding these, we can effectively prevent the customized corrosion of hexagonal guardrail net and extend the service life of the product.
Cold drawing wire is a metal cold processing, with wire rod as raw material, that is, the mouth of the steel bar. Cold drawing wire is a product produced by a series of processes such as shell stripping, which is a common wire. In the development and production of metal materials, cold drawing wire is a very common material, its performance is good, the range of use is very wide, manufacturers in processing are the use of cold processing to produce.
