Pharmaceutical industry demands to improve, microporous filter film development trend?

　　Pharmaceutical Network Technical Article: Microporous filter film is mainly used for sample analysis, especially chromatographic analysis of flow phase and sample filtration, to protect the column and infusion pump piping system and infusion valve slings and other good role At present, it is widely used in the production of sterile liquids, ultra-pure water manufacturing and air filtration, and in the laboratory, microporous filtration film is an important tool for detecting tangible fine impurities
At present, in the pharmaceutical and other industries, the microporous filter membrane can be found With the continuous development of the pharmaceutical industry, the requirements for microporous filtration membranes are also increasing Stimulated by the new market demand, the development trend of microporous filter film has also attracted wide attention in the industry Industry said, specifically, microporous filter film development trend is mainly in the following aspects
Equipment structure to be optimized It is learned that in the past the market microporous membrane is mostly uniform structure film, in the use of deep (internal) suction blockage phenomenon is serious, difficult to clean
In order to change the blockage situation and facilitate the cleaning of the equipment, the structure of microporous filter film needs to be changed urgently Among them, the asymmetric membrane has the characteristics of small separation layer hole, support layer hole is large, so the particle or colloid is only intercepted on the surface of the membrane, through the separation layer particles will not be sucked in the membrane At present, asymmetric microporous filter film has been widely concerned by the market
Production of elysion to be improved The industry said that microporous filtration film is being converted from gas diffusion gel phase to immersed gel medium phase conversion development, because the gas phase diffusion gel slow, so the production of pleasant nourishment is low, and because the wet film is exposed to moisture for a longer period of time, easy to produce defects, environmental conditions require high, the formation of the membrane is uniform structure film, and the asymmetric membrane prepared by the Loeb-Soliola gold iron method is high, local environment is easy to control, of course, the key is the choice of membrane materials and film-making conditions
Suitability to be adjusted It is understood that, with the rapid development of bioengineering, medicine and food industry, inorganic asymmetric microporous membrane is being highly valued by people, it is characterized by high temperature resistance, can be high-pressure steam disinfection And pressure-resistant, can be used at higher pressure acid, alkali and chemical resistance In addition, can also be cleaned under harsh conditions, in recent years, the development of better
The length of life of the equipment affects the user's production schedule and cost In recent years, users pay more attention to the cost-effective equipment at the same time, but also pay more attention to the service life of equipment
Among them, in the applied research, miscurrent microfiltration is a more active field in recent years, it can reduce the blockage of the membrane, prolong the service life, improve the amount of processing At present, the relevant component design, equipment assembly and development is also more active
Adaptability to improve the applicable performance of the device, the more advantages It is reported that capillary membrane has the advantages of large film surface area filling, good liquid flow state (internal pressure) and backflushing, etc., in the ultrafiltration membrane filter has been widely used
In addition, with the promotion of environmental protection concept, microporous filter film also needs to be developed in the direction of environmental protection It is reported that, with the fierce competition in the market, many manufacturers are currently in the porosity, diversity, purity, strength and other aspects of force The use of high-purity raw materials and additives production, improve pore rate, for adsorption and binding to provide a large surface area, and research and development of different types of filter film for users to choose from the market competition.
