How to prevent the corrosion of crusher accessories

In the process of using the crusher parts, the metal surface of the crusher is subjected to the chemical and electrochemical effects of the surrounding medium and is also subjected to friction or impact. The damage to the equipment parts is called corrosion wear.

The corrosion and abrasion of the crusher parts bring harm to the crusher equipment. The damage to the equipment parts is quite serious. Every year a large amount of metal is scrapped due to corrosion and wear, causing huge losses. The hazard of corrosion and wear is not only the loss of parts, but more serious is the damage to the structure of the crusher equipment, waste products and equipment accidents in the production, this kind of wear sometimes even limits the possibility of adopting new processes and new equipment. Therefore, it is of economic significance to study corrosion and wear and prevent corrosion and wear.

According to the principle of corrosion, metal corrosion and wear can be divided into two forms; one is electrochemical corrosion, which is caused by the effect of electrolyte, and local current is generated; the other is chemical corrosion, which is caused by dry gas or non-conductive liquid medium. the result of. The metal damage rate caused by electrochemical corrosion is relatively fast, the severe damage caused by corrosion and wear is *ly caused by electrochemical corrosion, and the damage rate of chemical corrosion to metals is relatively slow.

In order to prevent corrosion and wear, various new processes and methods have emerged in recent years, such as using corrosion-resistant alloys, stainless steel, etc. as materials for manufacturing parts, and using carbon products as corrosion-resistant materials has a better effect. From an economic and technical point of view, it is often used to add a metal or non-metal protective layer on the surface of the part, such as hot dipping, electroplating or metal spraying to add zinc, chromium, nickel, tin, copper, aluminum, lead Other metal materials are compounded on the metal surface, or painted (paint, varnish, mineral oil, petrolatum, paraffin solution, etc.) on the surface of the part as an anti-corrosion layer.
