5, there are no special requirements: such as whether to shrink packaging.
What are the differences between the hook fence net production plant used on the highway? The guest soil of galvanized zigzag net creates favorable conditions for the growth of vegetation on the slope. Its composition varies with the growth conditions of plants on the slope. According to the side slope rate, geological conditions, temperature, precipitation and other characteristics of reasonable selection of net types, galvanized hook mesh on the slope vegetation protection effect will be better. Highway and railway galvanized hook mesh, through the vegetation developed root system and mesh body closely combined, to achieve the purpose of protection of highway slope. The guest soil of galvanized zigzag net creates favorable conditions for the growth of vegetation on the slope. Its composition varies with the growth conditions of plants on the slope.
Galvanized hexagonal net is a kind of galvanized metal wire mesh, mesh shape is hexagonal.
(1) In the painting construction should pay attention to ventilation, moisture-proof, fire prevention. The working environment and painting tools should be kept clean, the pressure of the air pump should be controlled within 0.63MPa, and the safety valve should be checked for failure.
The quantity should be the same as the contract, cold drawing, carefully record the quantity of each specification and packing method. If there is a label, check whether the label is correct and take a photo to confirm. Each roll of iron wire is fastened with galvanized packing tape, and then tied with a very strong transparent plastic bag. The coated iron wire is wrapped with white braided cloth, and the galvanized iron wire is wrapped with green braided cloth, so as to ensure that the packaging will not be lax in the transportation process.
Material: galvanized silk
Good 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.
Wire rod to stop normalizing or soxaustenitizing treatment, large specifications with spheroidizing annealing instead. In the middle, especially before the waste product drawing process of thermal disposal throughout the selection of soxaustenitizing disposal. Decarbonization should be prevented during thermal disposal. Sulfuric acid or hydrochloric acid pickling was used to remove the oxide sheet after hot treatment. Coating (see lubrication carrier) can be dipped in lime, phosphating, borax disposal or copper plating.The material of small hexagonal mesh is the same as that of other hexagonal mesh, which is generally made of low carbon steel wire, stainless steel wire and galvanized steel wire as raw materials by the hexagonal mesh machine.
Because of the high carbon content, simple cracks occur during water quenching, so double liquid quenching (water quenching + oil cooling) is mostly used, and oil quenching is mostly used for small cross section parts. This type of steel is generally used after quenching by medium temperature tempering or normalizing or in the surface quenching state. Mainly used for manufacturing spring and wear-resistant parts.
Barbed wire even in the mining industry also has a higher embodiment, because the selection of low-carbon materials to make it has a general iron mesh does not have the flexibility, determined its plasticity in the use, and then can be used in hardware crafts in the deep processing production, as the wall plastering, inside leak prevention crack and so on. Its light net body, the lower cost, can let the customer realize its economic benefits.
