Properties and applications of paper-based friction materials (Part 2)
2.1 Effect of different lubricating oils
Due to the porosity of the paper base, the paper base friction material is greatly affected by oil. Paper-based friction materials are widely used in various machines, and the oil products used are also different. Therefore, the friction performance of the same friction material in different lubricating oils will be quite different.
2.2 Effect of different densities
Due to the porosity of the friction material, different densities, ie different porosity, also have a great influence on the friction performance. On the one hand, friction materials with different densities affect the thermal conductivity of friction materials, and affect the thermal fatigue and durability of friction materials; on the other hand, they affect the instantaneous bonding process of friction pairs and the lubrication state of friction surfaces, thereby affecting the change of friction coefficient Trend and its stability, so density is an important performance index of paper-based friction materials.
2.3 Influence of other conditions
The difference in use conditions also directly affects the characteristics of the friction material, such as surface pressure, speed and oil temperature, etc., which will not be described here. The specific impact depends on the test results.
Therefore, the coefficient of a specific friction material is not a specific value, but a range obtained through repeated tests for the friction coefficient between oil and a certain friction material according to different test conditions.
3. Application of paper-based friction material
At present, due to its excellent friction performance, Hangzhou Linan Hualong paper-based friction materials are widely used in brakes, gearboxes and other transmission equipment of various vehicles and construction machinery such as construction machinery, agricultural machinery and industrial machinery. important friction material.
The principles of paper-based friction materials are different in different vehicles (construction machinery, agricultural machinery, etc.) and in different applications of vehicles (service brake, parking brake, gearbox, etc.)
4. Conclusion
In order to meet the wider and harsher conditions of use, Hangzhou Linan Hualong is also working hard to develop paper-based friction materials with better performance, including wet friction materials with better performance than paper-based friction materials. At present, good progress has been made to provide customers with more choices for better applications.
