With the development of science and technology and the increasing maturity of production technology, my country has developed rapidly in three-layer and five-layer composite materials, and its application scope is becoming more and more extensive. Today we will learn about this material.
The three-layer and five-layer composite material is a composite material that uses a special process to compound the PTFE film on the surface of the clothing fabric, which is waterproof, breathable, windproof and warm.
Compared with other polymers, PTFE composites have unique advantages, but there are also some shortcomings, such as poor mechanical processing performance, large linear expansion coefficient, poor creep resistance, and easy cold flow. , poor wear resistance, difficulty in molding and secondary processing, etc., which limits its application.
At present, research on PTFE at home and abroad focuses on finding appropriate methods to modify it, improve its performance to a certain extent, and expand its application scope.
The three-layer and five-layer composite material has a microporous structure with staggered fibers. Through a two-way stretching process and high-temperature heat setting treatment, the microporous structure is very stable and can effectively intercept dust particles.
The pore size of the material is small and the distribution is concentrated. Surface filtration is achieved to achieve a dust removal efficiency of 99.9%~99.999%. For some extremely small particles with a diameter of 0.1um-0.3um, it can better prevent fine dust from entering the filter material.
Can operate at a continuous operating temperature of 240°C and an instantaneous temperature of 260°C.
