Minglie Rank F flat membrane for medical and health work is formed by three series of functions which are gas, liquid and functional use. Material use PTFE, PVDF is the main body, the reinforcement material is PET or PP. Among them, the gas filtration series is mainly composed of four models which are LF, KF, CF and QF. Liquid filtration series consists of FF, ZF, YF and VF, functional filtration series is mainly composed of XF-D, A, L, W. The blood leukocyte filtration material is composed by EB and EC group. FF is an ultra filtration membrane category, EB/EC category belongs to deep filtration, and the rest belong to the category of micro filtration membrane. Pore size range of Minglie flat membrane is from 0.02 to 10μm. This is similar to normal distribution, and has clear specification. The practice of four-balance theory, three-related principle and double cooperation effect make the membrane having specific hole geometry; modified membrane assures uniform, equality, permanent modification to all holes on the surface of the membrane by chemical method. The performance indicators such as functional group distribution in membrane surface, configuration of chain segment space, micro interface morphology, electrical properties and ionic strength are controllable and stable by functional groups, reaction activity, molecular assembly structure and the design of bonding mode of substrate film. Minglie membrane has many characteristics such as huge surface hole numbers, uniform pore size distribution, specially stable membrane pore structure and surface treatment technology, very economical initial fluxes and contamination levels, excellent environmental tolerance, low or selective adsorption and good after-processing. The selection of raw materials, the preparation of the process and the control of the production environment are in accordance with the requirements of the medical products. Membrane can be used in infusion, reagent preparation, patient / instrument protection, ventilation, blood treatment, diagnostic reagent carriers and other occasions. Therefore, the membrane has good value for the use of special medical film.
