Source:www.89897.com.cn      Release date: 2025年04月28日
Information summary:The Xylan coating on the valve stem has the following characteristics: 1.

The Xylan coating on the valve stem has the following characteristics:
1. Low friction coefficient: The friction coefficient can be as low as 0.005, which can effectively reduce the friction between the valve stem and other components, reduce the degree of wear, extend the service life of the valve stem and related components, and also help the flexible operation of the valve, reducing operating torque.
2. Self lubrication performance: With self-lubricating function, it can provide long-term lubrication for the valve stem under high pressure even without additional lubricant, ensuring smooth operation and reducing heat and noise generated by friction.
3. Excellent anti-corrosion performance: It can resist the corrosion of various chemicals. According to ASTM B-117 testing, after 1500 to 4000 hours, the red rust on the coating surface is less than 10% to 15%, which can effectively protect the valve stem from external corrosive media and improve the corrosion resistance of the valve stem in harsh environments.
4. Good high temperature resistance: It can withstand temperatures up to 260 ℃ and maintain stable performance in high temperature environments. It is not easy to deform, crack or fall off, and can enable the valve stem to work normally under high temperature conditions.
5. Strong wear resistance: The coating contains PP and PTFE dry film lubricants, which have outstanding wear resistance and can resist various solvents. It can operate continuously at a high temperature of 205 ℃, effectively preventing wear on the valve stem surface caused by friction, erosion, and other reasons, and maintaining the accuracy and surface quality of the valve stem.
6. Strong adhesion: It is tightly bonded to the surface of the valve stem substrate, has good adhesion, is not easy to peel off or detach, and can maintain complete protection during the use of the valve stem.
7. Multiple color options: There are various colors to choose from, such as blue, red, green, silver, black, etc., which can be customized according to actual needs. It can not only meet the functional requirements of anti-corrosion and lubrication, but also to some extent meet the needs of appearance decoration and labeling.
