Effect of advanced composite wear and corrosion resistant
coating on industrial equipment

Nowadays, the rapid development of energy industry can not be separated from modern industry, and the reliability and safety of industrial equipment will be damaged under various wear, high temperature, corrosion and complex natural conditions, thus increase the operating costs of enterprises. High-grade composite wear-resistant and corrosion-resistant coatings are based on the original base surface, and further enhanced, optimized and improved, according to the user's different conditions of use and media environment to rely on advanced engineering management technology for special customization, product through many fields, many years of user application feedback, accumulation of many excellent solutions, in the light of corrosion, corrosion, wear and chemical corrosion and other types of damage, in the structure and metal surface protection and repair and reconstruction of excellence. And widely used, especially in power, metallurgy, mining and other industries,especially in the boiler spraying, all kinds of refractory construction performance, can make products 10 times longer service life, reduce the number of maintenance, reduce the cost of product maintenance.

Reduce energy consumption, so that the long life cycle of equipment is well reflected. High-quality and efficient products and coating construction, greatly improve the efficiency. Taking KD9600 as an example, it is the best scheme to replace wear-resistant coatings of tungsten carbide, silicon carbide, wear-resistant ceramics, Teflon, etc. , avoid the construction products in the back and forth transportation process caused by damage and coating off. High wear resistance such as KD9600 composite coating and tungsten carbide coating price is the same,compared with Teflon coating can increase more than 10 times the life.

High wear resistance KD9600 composite coating and tungsten carbide coating price is equivalent, but the wear resistance of composite coating is much higher than tungsten carbide coating, Teflon coating. Compared with tungsten carbide coating and teflon coating, it can be applied on site and the construction time can be shortened by 3 times. Therefore, compared with tungsten carbide coating and teflon coating, it has the advantages of high efficiency, short cycle, flexible and convenient construction.|

The role of boiler heating surface spraying
1. To improve the abrasion resistance of boiler heating surface
During the operation of the boiler, the heating surface is subjected to erosion and wear by high temperature
and high pressure steam, so the wear resistance of the surface material is required. In this case, the use of
spraying technology can form a layer of dense wear-resistant coating on the surface of the heating surface,
greatly improve the wear resistance of the heating surface, extend its service life.

2. antiseptic
The boiler heating surface is often in the humid, high temperature, high pressure environment, easy to produce corrosion, which will not only affect the normal operation of the boiler, but also accelerate the aging of the boiler, to prevent the boiler long-term operation caused by tube explosion and shutdown accidents. The use of thermal spraying anticorrosive coating can reduce the risk of boiler abrasion to a certain extent, and protect the surface material of heating surface from being damaged.

3.Improve the combustion efficiency
As the heating surface wears and corrodes, its Surface roughness will gradually increase, which hinders the
transfer of heat energy and leads to a decrease in combustion efficiency. Spray technology can form a smooth
coating on the heated surface, reducing Surface roughness and increasing the efficiency of heat transfer, thus
increasing combustion efficiency. To sum up, spraying on heating surface of boiler can improve the abrasion
resistance, corrosion resistance and combustion efficiency of heating surface.
