Bag Filter For Semiconductor Manufacturing

The customized semiconductor filter bags are manufactured according to the increasingly stringent requirements of the filtration industry, using full sealing and filtration technology, which takes industrial technology to a new level and takes bag filtration to a new level. The filter material of the high-efficiency ultra-fine fiber filter bag is pure polypropylene, which has good lipophilic and hydrophobic properties, and no other chemical components are produced in the filtration process. The structural design of the semiconductor filter bag is divided into an inner layer, a coarse filter surface, and an outer layer, a fine filter surface. The inner layer of the coarse filter surface ensures sufficient dirt holding capacity, reduces filtration resistance, and the outer layer of the fine filter surface traps fine particles to ensure filtration accuracy. The cascade structure design ensures that impurities can be trapped layer by layer. At the same time, the combination of ultrasonic welding technology ensures extremely high sealing performance, and there will be no leakage from the bypass side during operation. High-efficiency semiconductor ultrafine fiber filter bag is suitable for liquid filtration such as electronic fine chemicals, petroleum products, food and medicine, coatings and inks, and water treatment. Their excellent oil-absorbing properties make them particularly suitable for oil removal in the paint and varnish industry.
