With the continuous transformation and upgrading of the national economy, green development has become the main theme of my country’s economic development. As an important area of ​​the environmental protection industry, the development of the water treatment industry chain is gradually improving, and the water treatment industry space is expected to be gradually released in the future. Polytetrafluoroethylene hollow fiber membrane is also increasingly used in the water treatment industry.

Polytetra fluoroethylene (PTFE) has a high degree of chemical stability and extremely strong resistance due to its special molecular structure. Due to its high and low temperature resistance, good non-stickiness, lubricity, excellent electrical insulation and aging resistance, scientists have used various methods to process polytetrafluoroethylene for a long time after its discovery. Vinyl fluoride material can be processed into various required shapes and used in almost all fields, including aerospace, petrochemicals, machinery, electronics, construction, textiles, medicine and other industrial sectors. The usage accounts for about 85% of the entire fluoroplastics The above has broad application prospects.

Hollow fiber membrane technology is a high-tech technology developed in the mid-1960s. It is also a widely used separation membrane form in current membrane water treatment technology. , has the advantages of high filling density, small floor space, high separation efficiency, stable operation, easy operation and low cost. It can be used for the treatment and reuse of sewage, the purification of municipal water supply, the separation, concentration and purification of solutions, etc. It has been widely used It is used in many fields such as environmental protection, energy, petroleum, chemical industry, food and so on.

Polytetrafluoroethylene hollow fiber membraneThe preparation process is: PTFE resin + lubricant→mixing→maturation→paste extrusion →Hollow tube→Degreasing→Stretching→Sintering. PTFE is considered an ideal hydrophobic membrane material due to its excellent corrosion resistance, thermal stability and hydrophobicity. However, it is difficult to dissolve, has poor melt fluidity, and is difficult to process. The current processing method for PTFE hollow fiber membranes is mechanical stretching, but the membranes prepared by this method have low porosity, which seriously restricts the efficiency of the separation process.

It is a fluorine material film manufacturer that integrates the R&D, production and sales of polytetrafluoroethylene hollow fiber membranes and membrane filter materials. The company has advanced PTFE film production lines, lamination and composite production lines, which are at the domestic advanced level. The company’s products are widely used in various fields. The company has always implemented the purpose of “quality first, reputation first” to provide users with high-tech, high-quality, high-performance, and high-level products.
