The quality of drinking water has always been a concern for many families. Many manufacturers have also seen this business opportunity and have produced household water purifiers. Nowadays, there are many brands of water purifiers on the market, so do you know what is the most important thing in a water purifier? Let’s take a look at the manufacturer of polytetrafluoroethylene ultrafiltration membrane.
The common household water purifier on the market is the terminal water purifier, and the most common terminal water purifier is ultrafiltration. Water dispenser and RO pure water machine. In addition to the stainless steel filter, PP cotton, activated carbon and other filter materials that we have already introduced, the main filter material in the ultrafiltration water purifier is the ultrafiltration membrane that plays an important role. Next we will introduce ultrafiltration membranes. Ultrafiltration can well retain minerals in the water and remove organic matter such as small bacteria in the water.
Ultrafiltration membranes can be divided into inorganic membranes and organic membranes according to the membrane material. Organic membranes are mainly made of polymer materials, such as cellulose acetate, aromatic polyamide, polyethersulfone, polytetrafluoroethylene, etc. Polytetrafluoroethylene ultrafiltration membrane is commonly used in water treatment. Depending on the shape of the membrane, it can be divided into flat membrane, tubular membrane, capillary membrane, hollow fiber membrane, etc. Ultrafiltration membranes used in household water purifiers are basically hollow fiber membranes.
Ultrafiltration is a membrane permeation separation technology that can purify, separate or concentrate solutions. It ranges from reverse osmosis and microfiltration to a continuous circular spectrum. Among them, ultrafiltration is between nanofiltration and microfiltration. It is defined as the cutting molecular weight of ultrafiltration is about 500~500000, and the similar value of the corresponding pore size is about 0.002-0.1 micron.
The polytetrafluoroethylene ultrafiltration membrane currently independently developed and produced is widely used in water treatment, with a pore size of 0.1μm-1μm , prepared by a two-way stretching process, can ensure that all small bacteria and impurities are trapped, and can be used in liquid filtration to achieve sterility. It has wide chemical applicability, resistance to strong acids and alkalis, and high ozone strength. Interested parties are welcome to enter the store for consultation.
