The updated evaluation revises the outcome of EFSA’s previous assessment published in 2016, which highlighted the need for more research to fill data gaps.
There is some evidence that ingested titanium dioxide does not completely exit the body. A 2015 review of animal studies and a few human studies suggests titanium dioxide can get absorbed into the bloodstream and expose other organs to damage.
The main customers of the barbed rope factory are still targeted at the farm and plantation customers for sales, because the demand for barbed rope is often very large.
The characteristics of these cages are small, light, easy to carry and easy to clean. For small animal cage, 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 “violence”, otherwise the cage in the “destruction” will occur under the welding or plastic crack.
Since galvanized iron wire will rust, we need to pay attention in the process of storage and use, try to store in a dry and ventilated environment, in the process of use to avoid damaging the surface of galvanized iron wire, we can slow down the time of galvanized iron wire rust.
Galvanized hexagonal net is a kind of galvanized metal wire mesh, mesh shape is hexagonal.
Therefore, the rust of galvanized black iron wire has a great relationship with storage. At the same time, after rust, it should also be reasonable for post-treatment to avoid affecting its use effect. Of course, when the black iron wire is galvanized, the thickness of the galvanized layer should be ensured, so that the possibility of rust can be reduced. Speaking of galvanized iron wire, perhaps many people think it is relatively rare, in fact, it is not.
Breeding cattle and sheep with barbed rope effect or better, because the advantages of barbed rope more. Then the barbed rope used for animal husbandry effect is good?
Annealing wire is widely used mainly because it has a good elasticity and flexibility, in the annealing process can be a good control of its hardness and softness, it is mainly made of iron wire, more commonly used in the construction industry tie wire use. When the wire factory is in production, the annealing wire will be processed according to the performance of the material, and its hardness will be changed according to the different demand, which can make it have more advantages, reduce the consumption of metal and reduce the cost of production.
Galvanized iron wire is a substance we often see in life. It is the zinc gradually plated on the metal surface through the unidirectional current in the electroplating tank. The production speed is slow, the coating is uniform, the thickness is thin, usually only 3-15 microns, the appearance is bright, the corrosion resistance is poor, and the corrosion will rust in a few months. Galvanized wire has the characteristics of thick galvanized layer, strong corrosion resistance, strong galvanized layer, etc., the products are widely used in construction, highway walls, Zahua, weaving nets.
Galvanized hexagonal net features: easy to use; Save transportation costs. It can be reduced to small rolls and wrapped in moisture-proof paper packaging, taking up less space. Coating thickness uniformity, stronger corrosion resistance; Simple construction, no need for special technology; It has strong ability to resist natural damage, corrosion resistance and adverse weather effects; Can withstand a large range of deformation, but still does not collapse. Fixed heat preservation and heat insulation effect.
However, in the actual production process, the wire may be affected by other factors that may cause the wire to lose its conductive properties. For example, if the thickness of the galvanized layer is too thick or the surface is not uniform, the current density on the surface of the wire will be uneven, which will reduce the electrical conductivity of the wire. Similarly, if the wire is stretched too much during wire drawing, it may cause the wire to break or the surface to deform, thus affecting its electrical conductivity.
Galvanized wire is divided into hot galvanized wire and cold galvanized wire (electric galvanized wire). Hot dip galvanizing is dipped in zinc liquid melted by heating. It has fast production speed, thick but uneven coating. The market thickness is 45g and can reach more than 300g. The color is dark, the zinc metal is consumed, and the matrix metal is formed into the entry layer, the corrosion resistance is good, and the outdoor environment of hot dip galvanized can adhere to decades.
The use of bundled galvanized wire with the development of industry and agriculture also expanded accordingly. Therefore, galvanized wire products in the industry, such as chemical equipment, oil processing, Marine exploration, transport, electricity, shipbuilding, metal structure, etc.), agriculture (such as sprinkler irrigation, dim room, building (such as water and gas transport, wire casing, scaffolding, house, etc.), Bridges, shipping, etc., has been widely use in recent years. Because galvanized wire goods have beautiful surface, good corrosion resistance and other characteristics, its use scale is more and more extensive.
If the surface of galvanized wire hair black, galvanized layer is thin and uneven, this galvanized wire is partly because the inventory storage time is longer, it may also be because the production technical requirements of galvanized wire, do not meet the standard standards and lead to galvanized wire quality problems. According to the use of galvanized wire is different, galvanized wire has soft and hard, so the galvanized wire for binding requires the flexibility of galvanized wire is better, the flexibility of galvanized wire is good, which can facilitate the operation of workers.
Large volume galvanized wire is made of high quality low carbon steel wire rod processing, is made of high quality low carbon steel, after drawing molding, pickling rust removal, high temperature annealing, cooling and other processes. Galvanized wire has good toughness and elasticity, the amount of zinc can reach 300 grams/square meter, with thick galvanized layer, strong corrosion resistance and other characteristics. Widely used in construction, handicrafts, silk screen preparation, highway guardrail, product packaging and daily civil and other fields. Galvanized wire is divided into hot galvanized wire and cold galvanized wire (electric galvanized wire).
