The different spacing of the thorn rope is mainly in order to save costs to consider, because if they are too close, then obviously a little waste of resources, but the installation is too sparse will not work. Usually the bottom spacing is about 10cm, and the top is up to 20cm, this is because the higher the place is more difficult to climb over, usually more than one meter without the help of tools it is difficult for ordinary people to climb over, and the bottom because of the relatively tight can prevent personnel from drilling in the past.
Zinc pot workers should be determined to do duty and responsibility. Do not leave the post without leave, always observe the change of hot plating wire galvanized layer, and according to the analysis results, master the asbestos block gap friction, how long it takes to press, replace the pressing face; Adjust the working face; Until all four faces of the asbestos block are used up, maintenance workers can continue to use the asbestos block after repair when necessary to reduce the consumption of asbestos block.
Now, hexagonal wire netting is widely used in Bridges, bridge piers and bridge bracket slope protection, cant bridge bracket, there are many people according to the gradient of slope to choose the right hexagonal wire netting, in gentle slope, people usually use bing slope protection system, and in the case of steep slopes, people will use the guest network gravity walls.
Crevice corrosion is a kind of corrosion in small area, especially in concealed position, which can form vicious corrosion cycle. Almost all the crevice corrosion can occur in a metal alloy, with gas containing active anionic neutral medium Z is easy to cause crevice corrosion, crevice corrosion often occurs in the aperture of 0.025 to 0.1 mm, because of long time gathered, the cracks will exist a series of impurities, coupled with the external environment of damp easily corrode the area of the gap is small.
The cage should be strong so that the bars cannot be bent or damaged by the parrot, and weak bars can be bent or damaged by the parrot and injure the parrot. Cages made of plastic coated railings can cause parrots to eat the coating and are not suitable. Quality cages are made of stainless steel, especially those made of colorful mild steel railings. Railing spacing is very important for the parrot’s safety, and the railing should always be small enough to prevent the parrot from poking its head out between the railing gaps. For small parrot species, column spacing of 1/2 inch (1.3 cm) is necessary. Medium parrot species such as grey parrots and Amazons require a 1 inch (2.5 cm) pitch, while great macaws can reach a pitch of more than 1 by inch (3.8 cm).
These citizens, who love the subway, rely on it and enjoy its speed, often like to call themselves the U-pin price. Is widely used in industry, agriculture, farming, construction, transportation and other welded wire mesh is used in the field of high quality low carbon wire line of welding and become, then after cold, hot dip plating, PVC plastic coated surface passivation, such as plasticizing processing, production of metal mesh with smooth surface, uniform mesh, solder joint is firm, stability, corrosion resistance, good corrosion resistance characteristics. The U nail price is made of high quality stainless steel wire row welding; For example, machine protective cover, animal animal fence, flower fence, window guard bar, channel fence, poultry cage and home office food basket, paper basket and decorative articles, more acid, alkali, welding firm, beautiful and other characteristics.
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.
Sodium and magnesium contain less combustible impurities, and when extinguished, they simply glow. Galvanizing belongs to the electrochemical processing process which is widely used on the surface of steel. So it is, first of all, because zinc coating (especially after supplementary processing, such as chromate treatment and phosphating) resistance to atmosphere and water is more stable, and the galvanized process itself this is cheaper and simple.
Wire mesh production of general selection of low carbon wire, after fine and accurate active welding equipment processing, the selection of galvanized process surface treatment. After the completion of the product, the net surface is smooth and regular, good integrity, strong and consolidated, even if part of the choice or pressure will not appear lax phenomenon.
The formation process of hot dip galvanized layer is between the iron matrix and the outside of the pure zinc layer, the formation of iron-zinc alloy process, the workpiece surface in hot dip plating when the formation of iron-zinc alloy layer, so that the iron and pure zinc layer is well combined. The process of large roll galvanized wire can be simply described as: when the iron workpiece is immersed in the molten zinc liquid, the first zinc and α-iron (body-centered) solid melt is formed on the interface. This is a crystal formed by the matrix metal iron dissolved with zinc atoms in the solid state. The two metal atoms are fused with each other, and the attraction between the atoms is relatively small.
