Multi-layer sintered mesh characteristics        1. High strength and good rigidity: It has extremely high mechanical strength and compressive strength, and has good processing, welding and assembly performance and is easy to use.        2. Uniform precision and stability: Uniform filtration performance can be achieved for all filtration precisions, and the mesh does not change during use.        3, the use of a wide range of environments: can be used in the temperature range of -200 degrees to 600 degrees and filtration of acid and alkali environment.        4, excellent cleaning: countercurrent cleaning effect is good, can be used repeatedly, long life (can be washed by countercurrent water, filtrate, ultrasonic filtration, melting, baking, etc.).
