I don’t know how much everyone knows about polytetrafluoroethylene high-efficiency filter materials. Let us study it together today.
Electret technology is particularly important in the industrial production of melt-blown filter materials.
Electret treatment can significantly improve filtration efficiency without affecting the physical structure of the material and without increasing filtration resistance.
There are many types of electret technologies in my country, with corona charging technology being the most common, and there are also technologies such as water electret and thermal air flow electret.
Under a certain process temperature and humidity, corona electrets can move charges from the “shallow well” to the “deep well”, making charge storage more stable; temperature affects charge mobility and the storage of charges inside the material. quantity.
Polytetrafluoroethylene high-efficiency filter material uses polytetrafluoroethylene as raw material. It is expanded and stretched to form a microporous film. This film is coated on various fabrics and substrates using a special process. Become a new filter material.
The membrane has a small pore size, about 0.2-0.5μm, uniform distribution and large porosity. While maintaining air circulation, it can filter all dust particles including bacteria, achieving advanced purification and ventilation purposes.
The polytetrafluoroethylene high-efficiency filter material produced has strong hydrophobicity, chemical resistance, waterproofness and low wind resistance, and can achieve high dust removal efficiency. For some poles with a diameter of 0.1um-0.3um For fine particles, the filtration level can reach H13-U16.
In addition, biaxially oriented film can undoubtedly achieve ultra-low emissions in intercepting various types of dust generated during the company’s production process, and it fully complies with current environmental protection standards.
