White household water purifier ① polymer film forming method to be selected are compatible. For example, the preparation of the immersion casting membrane, the polymer must be dissolved in a solvent appropriate and safe. Combined with a film-forming polymer and methods shall be selected to obtain the performance and quality can be repeatedly reproduced ultrafiltration membrane. ② polymer shall have to meet specific application object properties. For example, a cellulose-based polymer, because of the application of biotechnology to meet the required hydrophilic low protein pollution requirements, but it can not afford alkali cleaning agent; polyether sulfone having excellent alkali resistance, suitable for cleaning applications required NaOH but it is strongly affected by protein contamination and less resistant to strong solvents and chlorine. ③ need commercially available polymer water purifier rankings, guaranteed supply, quality and affordable prices. ④ polymers need good film formers. The logical requirement ultrafiltration membrane production is very important. Properties of the film forming process and subject to the final film structure. The nature of the film-forming process and the final film structure and obviously subject to a flexible polymer, legislation compliance, interaction within the chain and the chain between the polar functional groups, semi-crystalline and amorphous like. Casting solution should have aimed for easy storage and casting operations thermodynamic stability China's top ten water purifier rankings, solidified into glass (with sufficiently high T8) or converted to semi-crystalline solid phase (with sufficient Godin.) The nature, and not have the property of forming a rubbery film. The latter purifier which brand is good, the film is too soft and compressible no practicality. It also requires between the polymer by the polymer / polymer interactions between solvent /, form a compatible blend, thereby expanding the scope and implementation of film-forming polymer modified polymer. PS, PES and PVDF ultrafiltration membrane has become an important polymer, the portion attributed to them and other polymers (especially hydrophilic polymer) compatibility ultrafiltration membrane separation technology is a use of the screening process to the pressure difference across the membrane is a driving force, to membrane as a filter medium under pressure certain stainless steel ultrafiltration water purification machines, when the liquid flows through the membrane surface, ultrafiltration membrane surface of many small micro clouds hole only allows water and small molecules passed into the permeate, while the liquid volume is greater than the surface pore size of the membrane material were trapped in the feed side of the membrane, to become concentrated liquid, thereby achieving the purification of the liquid, the separation and concentration purposes. Per meter length of wire ultrafiltration membrane wall about 6 billion 0.01 micron pores, pore size allows only water molecules, beneficial minerals and trace elements in the water through, while the smallest bacteria are 0.02 microns or more, bacteria and therefore much larger than the volume of colloid bacteria, rust, suspended solids, silt, organic molecules and so be an ultrafiltration membrane interception down, in order to achieve the purification process.
