The difference between hot dip galvanizing and cold galvanizing

Hot-dip galvanizing refers to melting zinc at high temperature, adding appropriate amount of auxiliary materials, so that there is a zinc layer on the metal components. What is the difference between hot-dip galvanizing and cold galvanizing?   1. What is the difference between hot-dip galvanizing and cold galvanizing 1. The principle is different. Hot-dip galvanizing involves dipping steel into molten zinc to coat the metal on the part, while cold galvanizing uses electrochemical principles to prevent corrosion. 2. Differences in corrosion resistance. Hot-dip galvanizing is a chemical treatment, which is an electrochemical reaction. Cold galvanizing is a physical treatment. A layer of zinc on the surface layer is easy to fall off, so hot-dip galvanizing is more corrosion-resistant than cold galvanizing. 3. Different thickness. The thickness of hot-dip galvanizing can reach more than 10 microns, while cold galvanizing is thinner, about 3 microns to 5 microns. 4, the price and practicality are different. Cold galvanizing is cheaper than hot galvanizing, but hot galvanizing is more practical than cold galvanizing.   What are the applications of hot-dip galvanizing?   Its zinc layer is relatively thick and the process is relatively simple, and it is suitable for anti-corrosion of steel products in highly corrosive places such as strong acid and alkali. Its surface is rough and the decorative effect is relatively poor, so it is mainly used for the protection of steel components. Nowadays, semi-finished products such as galvanized steel sheets, steel wires and steel pipes on the market all use this process. This process is also widely used in industries such as electric power, transportation, petroleum and household appliances, so it has a relatively large range of use.   What are the applications of cold galvanizing? It can be used in civil engineering, such as steel bars, guardrails, etc., and can also be used in construction, such as handrails, scaffolding, three-dimensional parking lots, etc. It can also be used in electric power such as iron poles and transformer racks, and can also be used in shipbuilding industries such as buoys, locks, and piping.



Introduction to the role of anti-theft screws

Anti-theft screws are also called anti-disassembly screws. In today's society, major businesses use anti-theft screws to protect their own interests. effect 1. To safeguard the interests of merchants, merchants use anti-theft screws on their products. 2. Anti-theft function. Anti-theft screws are used in many outdoor products, because there are many drawbacks in management in the outdoors, and the use of anti-theft screws greatly reduces unnecessary losses. For example: anti-theft screws are widely used in outdoor guardrails. 3. Easy to use, it can be installed with a special wrench, no special and complicated tools are needed. The manufacturer will provide special tools to customers, so there is no need to worry about installation problems. 4. The appearance is beautiful and generous. 1. Removable anti-theft screws can be installed, including: inner five-point anti-theft screws, inner torx anti-theft screws, Y-shaped anti-theft screws, outer triangle anti-theft screws, inner triangle anti-theft screws, two-point anti-theft screws, eccentric hole anti-theft screws, etc. 2. Non-removable anti-theft screws can be installed, including: flat-shaped anti-theft screws (S-type anti-theft screws), carriage anti-theft screws, etc. Application range: Anti-theft screws have a wide range of applications, such as: electric power facilities, railway facilities, highway facilities, oil field facilities, urban lighting facilities, lamp car tires and public fitness equipment, etc. The product has superior performance and has received wide attention and praise from various industries in the society. Four major features: 1. The structure is simple and novel, the standard bolts are convenient for users, and a fastening nut is omitted, which integrates fastening and anti-theft. 2. For the first time in China, the principle of "reverse locking" is applied to make the anti-theft performance unique and reliable. At the same time, the anti-theft steel sleeve is used for comprehensive protection, so that the thief cannot start. 3. Anti-loose, self-locking, wide application range, old lines can be reinstalled. 4. It is easy to install and use, no special tools are needed, and it can be adjusted freely, which solves the problem that the existing anti-theft nut is difficult to re-tighten.
