Characteristics and functions of copper bushings Wear resistance: The wear resistance of copper bushings is relatively good. Equipment of different materials has different characteristics. The internal structure of copper bushing parts is relatively tight and will not be too loose. It has no pores or sand holes, so the copper bushing looks brighter and has a special color. And it is also very important that its hardness is relatively high.Characteristics and functions of copper bushings Wear resistance: The wear resistance of copper bushings is relatively good.

Hot-dip galvanizing principle: clean the iron parts, then treat them with solvents, dry them and immerse them in zinc liquid. Iron reacts with molten zinc to form an alloyed zinc layer. The process is: degreasing - water washing - pickling - plating assistance - drying - hot-dip galvanizing - separation - cooling and passivation. The thickness of the hot-dip galvanized alloy layer mainly depends on the chemical composition of the steel such as the silicon content, the cross-sectional area of the steel, the roughness of the steel surface, the temperature of the zinc pot, the zinc immersion time, the cooling speed, the cold rolling deformation, etc.Advantages of hot-dip galvanizing: 1. Low processing cost: The cost of hot-dip galvanizing for anti-rusting is lower than that of other paint coatings; 2. Durable: In suburban environments, the standard hot-dip galvanizing anti-rust thickness can be maintained for more than 50 years without repair; in urban or offshore areas, the standard hot-dip galvanizing anti-rust layer can be maintained for 20 years without repair; 3. Good reliability: The galvanized layer and the steel are metallurgically combined and become part of the steel surface, so the durability of the coating is more reliable; 4. Strong toughness of the coating: The galvanized layer forms a special metallurgical structure that can withstand mechanical damage during transportation and use; 5. Comprehensive protection: Every part of the plated part can be plated with zinc, even in recessed areas, sharp corners and hidden places, it can be fully protected; 6. Save time and effort: The galvanizing process is faster than other coating construction methods, and it can avoid the time required for painting on the construction site after installation.7. Low initial cost: In general, the cost of hot-dip galvanizing is lower than that of applying other protective coatings. The reason is simple. Other protective coatings such as sandblasting and painting are labor-intensive processes. On the contrary, the process of hot-dip galvanizing is highly mechanized and tightly controlled in-plant construction. 8. Simple and convenient inspection: The hot-dip galvanizing layer can be tested visually and with a simple non-destructive coating thickness meter. 9. Reliability: The specifications of hot-dip galvanizing are generally implemented in accordance with BS EN ISO 1461, which limits the minimum zinc layer thickness, so its anti-rust life and performance are reliable and predictable.
