The treatment of multiple high-salt wastewater in chemical, pharmaceutical and other industries has always been one of the key issues waiting to be solved for the green development and clean production of my country’s industry. In this regard, the role of PTFE low-resistance filtration membrane has always been prominent.
Currently, the raw materials for melt-blown nonwoven fabrics in the world include polypropylene (PP), polybutylene terephthalate (PBT), polylactic acid (PLA), polyurethane (TPU), etc.
PP is the most commonly used raw material in melt-blown production. Its melting point is around 164~170℃. It has good melt fluidity during processing and short production process. It is widely used in the field of filtration.
PTFE low-resistance filter membrane has a fibrillar microporous structure, the porosity can reach more than 88%, there are 1.4 billion micropores per square centimeter, and the pore size ranges from 0.1μm-0.5μm.
Generally, this film is coated on various fabrics and substrates using special processes to become a new filter material.
It is one of the materials with the best corrosion resistance in the world. Except for a few chemicals such as chlorine trifluoride and liquid chlorine, it is resistant to all other chemical reactions and is insoluble in strong acids, strong alkali and organic solutions. It does not change in hydrochloric acid.
The temperature resistance range is -195℃～250℃, and the long-term use temperature is -100℃～250℃.
It is a manufacturer of ptfe low-resistance filter membrane environmentally friendly materials that specializes in R&D, production and sales.
