Post time: 24-08-22Good galvanized wire, plating thickness of 3- 4 mm, zinc adhesion should be less than 460 grams/m, that is, the average thickness of zinc layer is not less than 65 microns. When the thickness of plated parts is greater than 4 mm, the zinc adhesion should not be less than 610 g/m, that is, the average thickness of zinc layer should not be less than 86 microns. Standard galvanized wire coating must be uniform, galvanized layer basically uniform with copper sulfate solution test etching five times no dew iron. For standard galvanized wire coating adhesion requirements, the zinc layer of plated parts should be firmly combined with the basic metal and have enough adhesion strength, after hammer test does not fall off, not convex.
There are two main points to choose the blade to stab the rope
- The patented technology is used to regularly put zinc blocks into the plating aid pool, so that the bivalent iron in the plating aid becomes trivalent iron, and plays an important measure to stabilize the PH value within a numerical range, and also facilitate the filter to filter out the trivalent iron ions in the plating aid; The trivalent iron ion is controlled between 0.3 and 1.0g/L; When hydrogen is not released in the plating aid, the zinc block is continued. It is an effective measure to reduce zinc slag, improve the fluidity of zinc liquid and reduce the thickness of zinc layer to give full play to the function of plating aid filter.
Welding net is made of high quality low carbon steel wire row welding, and then cold plating (electroplating), hot plating, PVC plastic and other surface passivation, plasticizing treatment, smooth surface, uniform mesh, welding spot firm, local machining good performance stability, corrosion resistance, corrosion resistance. Features: stainless steel welding net selection of high quality stainless steel wire row welding, more acid, alkali resistance, welding firm, beautiful, widely used characteristics.
- The electrolytic deposition of large roll galvanized wire zinc-chin layer is basically the following two kinds of electrolyte: zinc is mainly in the form of zinc cation hydration in the solution; Zinc is mainly present in solution as complex anion. Acid electrolyte belongs to one class, complex cyanide and zincate electrolyte, and nickel sulfate electrolyte constitute the second class. Cyanide electrolyte and acid electrolyte are of great significance.
The production process of stainless steel blade barbed wire is basically similar to that of galvanized blade barbed wire, and the blade size is usually determined according to the mold.
5, the concentration of plating aid can not be too high, which is a factor that can not be ignored to reduce zinc consumption. The concentration of plating aid should not be too high. The galvanized line must be added with ammonium chloride and zinc chloride according to the data of laboratory analysis, and the specific gravity of the composite solution should be controlled within the range of 50~80g/L. If ammonium chloride or zinc chloride is arbitrarily added without the results of laboratory analysis, it should be criticized and educated, and economic treatment should be given if necessary.
- The advantages of hook net hook net raw material resolution of its use, used for road guardrail, sports stadium fence, etc., because the weaving characteristics of hook net can make the guardrail both beautiful and useful, have a good ability to hit, and can extend the service life, not easy to fade to prevent the effect of beautiful. And can also be used for family interior decoration, because its plasticity is very good so the use is also very much, is now many local are widely used.
Post time: 01-02-23Galvanized 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.
Razor wire, also known as razor wire and razor net, is a new type of protective net. Blade barbed wire has beautiful, economic and practical, good anti-resistance effect, convenient construction and other excellent characteristics, at present, blade barbed wire has been widely used in many countries of industrial and mining enterprises, garden apartments, border posts, military fields, prisons, detention houses, government buildings and other countries of the security facilities.
6, passivation to remove hydrogen parts should be passivation after the removal of hydrogen, passivation before the application of 1%H2SO4 or 1% hydrochloric acid activation 5~15s. Passivation shall be treated with colored chromate unless otherwise specified in the design drawings.
- Galvanized hook net price is low: galvanized anti-rust cost is lower than the cost of other paint coating; Galvanized hook mesh durable: galvanized layer and steel is metallurgical combination, become a part of the steel surface, so the durability of the coating is more reliable; Galvanized hook net impact resistance: galvanized layer forms a special metallurgical structure, this structure can withstand mechanical damage in transport and use; Galvanized hook mesh quality is high: every part of the plated parts can be plated with zinc, even in the depression, sharp corners and hidden places can be fully protected.
Post time: 30-08-22- We have to carefully choose a good cage for the parrot, so that it has a comfortable home.
Now the production of stainless steel blade barbed rope unless it is specially customized model, under normal circumstances is the use of 22mm knife length mold production, that is, we usually say BTO-22 type. It is not necessarily such a specification from 11mm to 65mm are specifications. Unless the customer insists on the length of the customized requirements, the barbed rope manufacturers produce is BTO-22 stainless steel blade barbed rope.
- The application range of small hexagonal net is also relatively wide, can be used for building wall fixed insulation layer, pipeline, boiler fixed insulation, decoration and other fields.
- 2, the smelting process of the production enterprise will also affect the corrosion resistance of stainless steel.
The bonding and anchoring function between the cold rolled ribbed steel bar and concrete is outstanding. In reinforced concrete structure, the width of black iron wire processing crack is smaller than that of circular steel bar, even than that of hot rolled thread steel bar. Therefore, it is used in the component, which fundamentally eliminates the phenomenon of steel wire sliding and damage, and improves the load bearing ability and crack resistance ability of the component end.
Post time: 07-11-22- The most obvious gap in a short time is the cross section of this piece, hot dip galvanized barbed wire because it is the surface anti-corrosion treatment, so in the cross section of this piece will appear rust, and stainless steel barbed wire because the internal raw materials and surface raw materials are consistent, so there is no such situation.
- In addition to these reasons, we should also pay attention to the tooling and process must be stable, and regular testing should be done to ensure the uniformity of galvanized layer.
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.
- Second, word of mouth selection
1, no paint and maintenance, long new not old, exempt you from maintenance fatigue and trouble, the lowest comprehensive cost. Stainless steel wire mesh can be used as poultry cage, egg basket, channel fence, drain tank, porch guardrail, anti rat net, mechanical protective cover, livestock and plant fence, grid frame, etc.
