Clean rooms include electronic factory dust-free workshops, GMP clean rooms, biological laboratory clean areas/biological cabinets, cosmetic workshops, clean laboratories and other workplaces, depending on the degree of cleanliness. It is divided into level 100, level 1000, level 10,000, level 100,000, level 300,000, etc. To achieve good cleaning results in a clean room, we must not only focus on taking reasonable air-conditioning purification measures, but also require crafts, construction and other majors to take corresponding measures: not only must there be reasonable design, but also careful construction and installation that conforms to specifications. , as well as the correct use of clean rooms and scientific maintenance management. At the same time, the selected sterile workshop purification filter material is also very important.
Clean rooms adopt laminar flow (unidirectional flow) or turbulent flow (turbulent flow, non-unidirectional flow) by using HEPA or ULPA filters. ) airflow principle to control particles in the air. Laminar or unidirectional airflow systems direct filtered air in a constant flow downward or horizontally to filters located on the wall near the cleanroom floor or for recirculation through raised perforated floor panels. Laminar air flow systems are typically used on 80% of the cleanroom ceiling to maintain a constant flow of air.
The sterile workshop purification filter material currently independently developed and produced is the core filter material of clean room filters and is suitable for applications from level 1 It adopts a special processing technology and is a microporous film made by calendering, extrusion, biaxial stretching and other methods. This kind of membrane has excellent breathability, corrosion resistance, aging resistance, temperature resistance and other properties. According to the usage requirements, the pore diameter can be between 0.1-10um, the thickness can be between 2-100um, the porosity can reach 50%–80%, and there are up to hundreds of millions of micropores per square centimeter.
ptfe film manufacturer specializes in the production of sterile workshop purification filter materials. It has a full set of advanced production equipment and technology, and also has an advanced The clean room and independent composite slitting workshop ensure the production quality of ptfe membrane; the product materials produced are all imported raw materials, with high uniformity, stable performance and good air permeability. Interested parties can enter the store for consultation.
