The fiber diameter of the disposable cloth mask filter membrane is between 100 and 200 nanometers, which can better prevent fine dust from entering the filter material, just like a first layer of artificial dus…

Three-layer and five-layer high-efficiency filter paper has many uses and can play an important role in industrial sectors, electronics factories, military equipment, medical and health care and scientific rese…

Although a certain amount of colorant is added to the ptfe bubble point film composite material, it still has good electrical insulation and is suitable for the insulation and classification identification of w…

The three-layer and five-layer high-efficiency filter paper has a smooth surface and is resistant to chemicals. It is laminated to the surface of ordinary filter materials and functions as a disposable dust lay…

The fiber diameter of the three-layer and five-layer high-efficiency filter paper is between 100 and 200 nanometers, which can better prevent fine dust from entering the filter material. It is like a first laye…

Three-layer and five-layer high-efficiency filter paper is made of polytetrafluoroethylene (ptfe) material through special processes such as mixing, extrusion, extrusion, calendering, and biaxial stretching. Th…

Thin-film solar cells can be manufactured using low-cost glass, plastic, ceramics, graphite, metal sheets and other different materials as substrates. In addition, they are not affected by price fluctuations of…

Three-layer and five-layer high-efficiency filter paper is mainly a dust filtering device used to eliminate radioactive particles. Its main feature is that the filter material is very thin and has a pleated sha…

Thin-film solar energy is particularly good in low light. As we all know, there is not enough sunshine every day of the year, especially in winter and spring, when rainy and snowy weather often occurs. At this …
