At present, because Teflon liquid filtration membrane has the advantages of high temperature resistance, corrosion resistance, air permeability, and surface filtration, it is loved and used by more and more people.
Teflon liquid filtration membranes are classified by the size of the raw water particles they retain. The membrane pores are divided into microfiltration membranes (MF), ultrafiltration membranes (UF), nanofiltration membranes (NF) and reverse osmosis membranes from coarse to fine. (RO).
MF membrane has a pore size of 0.05um or more, or a molecular weight of 1000 or more, and is designed to remove colloids and high-molecular organic matter.
NF membrane pore size is 100~1000 molecular weight.
The substances it removes are between UF and RO to remove trihalomethanes, odors, color, pesticides, soluble organic matter, Ca, Mg, etc.
RO separation particle size is tens of molecular weight, and it is targeted at removing table salts and inorganic salts.
The pressure of RO permeate water is 1 to 2 times greater than its permeate pressure.
my country has also begun to develop PTFE stretched membranes since the 1970s, but it has been stuck in the uniaxial stretching process for a long time. Since the 1990s, individual units have developed and produced biaxially stretched microfiltration membranes. Membrane products are mostly focused on the development of waterproof and breathable textiles [4,5]. In order to produce high-quality biaxially stretched PTFE microporous membranes, we paid special attention to the relationship between various factors and membrane pore performance and morphological structure during the development process. , to optimize the production process conditions.
PTFE membrane manufacturer specializes in the production of Teflon liquid filtration membranes. It has a full set of advanced production equipment, an advanced clean room and an independent composite slitting workshop to ensure the production quality of PTFE membranes; it adopts American Imported production and testing instruments are used to test the quality of PTFE film, and have also passed international SGS testing and certification, as well as ISI testing and certification.
