There is no adhesion test of powder spraying or fluorocarbon spraying on packaged galvanized wire, but there are two points for reference: first, in sealed or air-free environment, non-metallic volatiles can corrode zinc coating; Second, zinc at higher than 230 degrees (c) will cause the matrix metal brittle. And powder spraying and fluorocarbon spraying are to be baked at a higher temperature and in a sealed environment, causing rapid corrosion of zinc, resulting in loose corrosion film resulting in coating adhesion decline, and even lead to (matrix) steel wire brittle situation may exist.
And high quality data and production cost and production conditions are bound, so some welding screen manufacturers did not meet the requirements of this aspect, natural in this case there is no way to improve product strength. In addition to data, and produce process, even if again good data, but the factory did not meet the requirements of production process in welding, also can form the product under the high pressure welding, so it is also a kind of strength on the decline, process conditions of different manufacturers also have very big difference, so it formed a shopping mall on the above products are differences of strength.
The common weight standard of galvanized barbed rope is 25kg per coil, and the length of each coil varies from 220-250 meters according to the specifications of the barbed rope. And of course we all know that the heavier the disc the longer it is. But there is one point that is worth our attention, that is, the hollow inside the general larger disk is relatively small, and the hollow inside the lighter galvanized thorn rope is relatively large. The purpose of this is to reduce the number of bending of the thorn rope and make it easier and more beautiful when installing, on the other hand, it looks larger in appearance.
The characteristics of hexagonal net: solid structure, flat surface, with good corrosion resistance, oxidation resistance and other characteristics: used for raising chickens, ducks, geese, rabbits and zoo fences, mechanical equipment protection, highway guardrail, sports places Seine, road green belt protection net. The screen in the production of box shaped container, with stone filled with cages, can be used to protect and support seawall, hillside, road and bridge, reservoir and other civil engineering, is a good material for flood control and flood resistance, namely (stone cage net, stone cage cage).
There are many kinds of galvanized solution, which can be divided into cyanide plating solution and cyanide plating solution. Cyanide galvanizing solution has good dispersion and covering ability, coating crystallization is smooth and fine, simple operation, wide application range, has been used in production for a long time. 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.
Because the coating obtained is thicker, hot-dip galvanizing has very good protective function than electric galvanizing, so it is an important maintenance coating for iron and steel parts in strict working environment. Hot-dip galvanized products are widely used in chemical equipment, petroleum processing, Marine exploration, metal structure, electric power transportation, shipbuilding and other occupations. In the field of agriculture, such as pesticide irrigation, greenhouse and construction industry such as water and gas transportation, wire casing, scaffolding, Bridges, highway guardrail and other aspects, it has been widely used in these years.
