Membrane distillation method is a thermally driven membrane separation technology using a microporous hydrophobic membrane as the separation medium. It can effectively realize the treatment of high-concentration salt water systems, and has the characteristics of high efficiency, low consumption, and environmental friendliness. This is mainly due to the PTFE hydrophobic membrane material.
Physical adsorption is to realize the hydrophobic modification of nanocellulose through the adsorption of surfactants, quaternary ammonium salts or copolymers by nanocellulose. The physical adsorption method has a simple process flow and can well retain the integrity of nanocellulose. It is a simple and environmentally friendly modification method. However, in the physical adsorption process, the modifier mainly relies on weak binding forces such as van der Waals forces and hydrogen bonds to interact with nanocellulose.
The special structure of ptfe hydrophobic membrane makes it have good thermal stability, chemical stability, insulation, lubricity, water resistance, etc. High temperature resistance, wide operating temperature range, can be used continuously for a long time at 260℃ (high temperature, instantaneous temperature can reach 280℃); strong chemical stability, corrosion resistance; good self-lubricating, extremely low friction coefficient, little filter wear; PTFE The surface tension of the membrane is very low, and it has good non-stickiness and water repellency.
The PTFE hydrophobic membrane produced by the manufacturer uses imported raw materials and has a full set of advanced production equipment. The clean room and independent composite slitting workshop ensure the production quality of PTFE film; production and testing instruments imported from the United States are used to test the quality of PTFE film, and it has passed international SGS testing and certification, as well as ISI testing and certification.
