Product advantages and problem solving
(1) Solve the problem of material failure under high temperature environment
Traditional metals or ordinary ceramics are easy to be oxidized and deformed at high temperatures, while boron nitride ceramic cylinders remain stable above 1000 ° C, extending equipment life.
(2) Improve the heat dissipation efficiency of electronic equipment
High thermal conductivity can effectively reduce the operating temperature of electronic components to avoid overheating damage.
(3) Reduce mechanical wear and maintenance costs
Self lubrication features reduce friction loss, suitable for high wear environment, and reduce downtime for maintenance.
(4) Adapt to harsh chemical environment
Corrosion resistance makes it suitable for acid, alkali and molten metal environment to avoid material degradation.
