Today I will tell you about the ptfe liquid filtration membrane produced and developed by the company. Let us learn more about it in detail.
Filtration is one of the most common separation and purification methods, usually used for the separation of liquid or gas mixtures.
The principle is: the fluid in the mixture passes through the filter medium under the action of driving force (gravity, pressure, centrifugal force, etc.), the solid particles are intercepted, and the fluid passes through the medium, thereby achieving the separation of fluid and particle objects.
Nowadays, there are many materials that can be used as filter media, which usually require properties such as porous, stable physical and chemical properties, heat resistance and chemical corrosion resistance.
The ptfe liquid filter membrane is one of the commonly used filter media in industry! The preparation of PTFE filter membrane is mainly made by mechanical stretching of PTFE material.
After the dry PTFE fine powder and additives are fully mixed, it enters the extruder. The powder is pushed and extruded into strips of PTFE, as shown in Figure 1, and then rolled into a film under a rolling machine. Heated and volatilized After removing the additives, it can be stretched vertically and horizontally, and then through heat treatment, shaping, cutting and rolling, the ptfe liquid filtration membrane can be obtained. The ptfe filter membrane produced not only has excellent chemical stability, thermal stability, electrical insulation, but also has Excellent waterproof, windproof, moisture-permeable, breathable and stable charge storage properties.
It is a new membrane material with great application prospects in many fields.
Can be based on user requirements.
The optimized combination of key technical parameters such as speed ratio, pressure ratio, operating temperature, etc. can realize online control of air permeability, thickness and void ratio according to the ratio and pore-forming medium to meet the different requirements you need. .
