Today I will take you to learn about a new type of material, which is a three-layer and five-layer composite material. Let’s take a look at the details.
Coated filter material is a new type of filter material for dust removal and materials.
The surface is very smooth after coating treatment. The dust removal principle is called microporous filtration. It mainly uses surface filtration. Almost 100% of the filtered materials are intercepted, and it has extremely high dust removal efficiency.
The pore diameters (usually the average pore diameter) of three-layer and five-layer composite materials are 0.5um, 1um, and 3um. The purpose is to adapt to dust of various particle sizes. The dust separation performance is excellent and can be separated at high temperatures. run.
Among them, the polytetrafluoroethylene microporous membrane is made of polytetrafluoroethylene resin and is formed by biaxial stretching through a special process. The porosity can exceed 85% and reach as high as 1.5μm.
Figure 1 shows the microporous structure of the polytetrafluoroethylene membrane.
To this end, two types of PTFE filter membranes were collected, one is a strong acid and alkali resistant type, and the other is a high temperature resistant type. They are both 150mm in diameter. The pore size of the strong acid and alkali resistant type is 0.22μm, and the pore size of the high temperature resistant type is 0.22μm. is 1μm.

PTFE film manufacturer specializes in the production of three-layer and five-layer composite materials. It has a full set of advanced production equipment and technology, and also has an advanced clean room and an independent composite slitting workshop to ensure the production quality of PTFE film; the products produced The materials are all imported raw materials, with high uniformity, stable performance, good air permeability, and the filtration efficiency can reach 99.999995%! It can basically meet the filtration efficiency grade requirements of sub-high efficiency, high efficiency and ultra high efficiency filters.
