Classification of Teflon proton membranes: According to differences in physical and chemical properties, it can be divided into woven membranes, non-woven membranes (non-woven fabrics), microporous membranes, composite membranes, diaphragm paper, rolled membranes, etc. kind.
The main function of the battery separator is to separate the positive and negative plates in the battery to prevent short circuits caused by direct contact between the positive and negative plates. At the same time, because there are a large number of micropores in the separator, the positive and negative ions in the battery can pass through the micropores. The electrons pass through freely and migrate between the positive and negative plates to form an internal conductive circuit of the battery, while the electrons migrate between the positive and negative electrodes through the external circuit to form a current for use by electrical equipment.
Teflon proton membrane is a non-toxic, odorless and tasteless milky white highly crystalline polymer with a density of only 0.90–“0.91g/cm3. It is one of the lightest varieties of all plastics currently.
It is particularly stable in water, with a water absorption rate of only 0.01% and a molecular weight of about 80,000 to 150,000.
The formability is good, but due to the large shrinkage rate (1%~2.5%), thick-walled products are easy to dent, and it is difficult to meet the requirements for some parts with high dimensional accuracy. The surface of the product is glossy.
PTFE film manufacturer specializes in the production of Teflon proton membranes. 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 membrane; the product materials produced They all use 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.
