The height of the shield should not be less than two meters. The length of the shield should be the width of the journey and the extension 10 meters away. The vertical load of the handrail on the bridge is 1.2KM/m, and the horizontal external load is 2.5KM/m, both of which should be calculated separately. Galvanized hook mesh belongs to a hook mesh, it is the selection of galvanized wire, hot-dip galvanized wire as raw materials, woven through the hook mesh truncated.
(2) Packing and binding galvanized shaft wire order notes: ① the galvanized iron wire shall not be damaged when the tightening. (2) Stop the use of more than two strands of galvanized iron wire around the operation method. ③ The diameter of galvanized wire for pulling should not be less than 4mm, and the diameter of galvanized wire for binding should not be less than 2.6mm. (4) Galvanized iron wire shall not be used as waist hoop down reinforcement, usually not used as a whole binding. Warehouse galvanized wire is mainly used to block and distinguish the function of the area, warehouse galvanized wire is one of the primary use of galvanized wire, warehouse galvanized wire primary layout features are as follows: layout: Column mesh frame, column to choose square steel pipe, galvanized wire frame is also a small square pipe as the data, column and mesh frame corresponding direction are welded connecting ear piece (flat iron), column and mesh frame through the connection of the ear piece bolt fixed, column bottom welding plate, column bottom plate through expansion bolts and fixed on the ground.
Wire factory introduction annealing wire is widely used mainly because it has good elasticity and flexibility, in the process of annealing can be very good control of its soft and hard degree, it is mainly made of iron wire, more often used in the construction industry tied wire use. In the production of annealing wire will be processed according to the performance of the material, according to the demand for different degree of hardness of its soft change, can make it has more advantages, can reduce the consumption of metal, reduce the cost of production.
Any application environment, users want a better the strength of the welded wire mesh, only need to improve its intensity, will make better the habit of using demand, but to be improved in the strength of this product, also need yo have a variety of conditions, will need to see factory in produce what kind of material, the strength of the product also is the material strength, But a manufacturer in the data does not fit the strength requirements, after all, there is no way to make the strength of the product progress, so this is the condition to.
Iron products are common metal products in life. Iron products appear everywhere in our life, but there is a big problem in using iron products. Iron products will rust, and when rust occurs, it will affect the use and appearance of iron products. Adding non-metallic coating: clean, dry and coat the surface of iron and steel products with a layer of protective materials, such as oil, mineral grease, rust-proof grease, plastic and lacquer.
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.
1. Principle. Because zinc does not change easily in dry air, and in humid air, the surface can form a very dense film of zinc carbonate, which can effectively protect the interior from corrosion. And when the coating is damaged for some reason and the matrix is not too large, the zinc and steel matrix form a micro cell, so that the fastener matrix becomes the cathode and is protected. It is widely used in automobile transportation and other industries, but what is needed is the trivalent chromium passivation layer, zinc nickel alloy plating closed coating, reduce the harmful and toxic layer of hexavalent chromium passivation.
There is a connection between the hook mesh and the aperture, in short, the general hole small hook mesh, the wire is also very small; Aperture is large, hook mesh wire is generally larger. The weaving of the hook mesh also has certain rules, using the first pre-bent into a wavy wire, and then woven into the hook mesh. According to the knitting method, the hook mesh can be divided into: closed weaving, two-way plain weaving, one-way corrugated weaving, two-way plane weaving, two-way corrugated weaving, rectangular hole weaving.
A pet carrier can be used as an indoor or outdoor pet house. The dog cage is equipped with a fixed food basin and water fountain, and the foot plate pet cage rubber pad has bayonets on four sides to be splintered. It can be spliced, cut and disassembled according to the size of the cage. It is convenient and easy to clean. It can solve the problem of pinching the feet of the puppies in the ordinary cage and prevent the puppies from causing adverse reactions in the development. The dividers are breathable and comfortable, and can be used as heat shields for pets in summer. A puppy with small feet, no feet, no pinching.
Hot dip galvanizing is dipped in zinc liquid melted by heating, with fast production speed and thick but uneven coating. The market allows a low thickness of 45 microns and a high of more than 300 microns. The color is dark, the consumption of zinc metal is much, the formation of infiltration layer with the matrix metal, the corrosion resistance is good, and the outdoor environment of hot dip galvanized can be maintained for decades. Application range of hot dip galvanizing: because the coating is thicker, hot dip galvanizing has better protective performance than electric galvanizing, so it is an important protective coating for iron and steel parts in harsh working environment. Hot-dip galvanized products are widely used in chemical equipment, petroleum processing, Marine exploration, metal structure, power transmission, shipbuilding and other industries, in the field of agriculture such as sprinkler irrigation, greenhouse and construction industry such as water and gas transmission, wire casing, scaffolding, Bridges, highway guardrail and other aspects, has been widely used.
