    Treatment of gaps between doors and windows in clean rooms

    Oct 22, 2020

    Clean room door and window gap treatment: Generally speaking, clean room doors and windows have three types of structural gaps. The first category is: the combined splicing and the installation gap between the door and the clean room door; the second category is: the overlap gap between the door and the opening fan; the third category is: the installation gap between the glass or other core boards. The nature is different and their proportions on the clean room doors and windows are also different. Therefore, the airtight measures adopted for the airtightness of clean room doors and windows are not completely the same.   Fixed gap treatment: Not only is the number of installed gaps in each clean room relatively small nowadays, but the combination of the door and the opening is relatively hidden after decoration, and it is a fixed gap that is easier to seal. The connection between the rib and the periphery of the hole should be firm, not only for the closed clean room doors and windows, but also the requirements of the general clean room door structure. Due to the large and fierce force of the clean room door, special attention should be paid to the process and the fixing of the clean room door. Whether the fixed points around the opening are firm and stable, but for closed clean room doors and windows, it must also be emphasized that the gap between the chamber and the clean room door or the hole should be tightly filled, and then covered with indoor and outdoor wall decoration layers. The air tightness of this type of gap is basically guaranteed. The second type of fixed gap is the installation gap of glass or other core panel. The treatment of the movable gap: How to overlap the opening fan of the clean room door and the frame material is the key to the design of the clean room door seal. The gap in the lap joint is different from the fixed gap. Because the movable fan needs to be opened, the wood can adopt the "one-and-for-all" sealing measures. Compared with Zhou, the opening fan of the clean room door is larger, and the movable gap occupies a larger proportion of the total structural gap of the clean room door. The number of openings of the clean room door is much more frequent than that of the clean room. The working conditions of the gaps around the door leaf are also more complicated. Take a single flat open clean room door as an example. The two sides along the vertical direction are small. The side with the handle is often subjected to various frictions or collisions during passage, and the side with the hinge is The direction of force applied to the bore due to the rotation of the fan is completely different from the other three sides.

    1) Choose materials with good airtightness and small deformation due to temperature changes; when the wall is installed with light steel keel and insulation materials, non-combustible materials or non-combustible materials should be used; (2) The inner wall and ceiling surface of the clean room should be smooth, smooth, free of micro-patterns, avoid light reflection, and be corrosion-resistant. The corners of the wall and the floor should be smooth. Light steel keels are used as partition walls, and measures to prevent collisions must be taken; (3) The floor of the clean room should be good and smooth as a whole, with wear resistance, corrosion resistance and impact resistance. In addition, it should have anti-static and easy cleaning and dust removal functions; (4) When the light ceiling grid is used as the technical inspection space, the maintenance channel shall be laid in the space to the discharge outlet; (5) The exterior wall windows of clean rooms and personnel clean rooms must have good air tightness and have the function of preventing air leakage and condensation; (6) The shape of the doors and windows of the clean room is a simple, smooth structure that is not easy to retain dust and is easy to clean; do not set thresholds; and in order to prevent bacteria from being generated by moisture or deformation of doors and windows, wood products cannot be used for doors and windows in the clean area; (7) The windows of the clean room should be opened toward the room with high air cleanliness level, and the windows should be of sufficient size to facilitate the installation, repair and exchange of general equipment; (8) The inner wall of the clean room for installing doors and windows should be flat, and no window sills should be avoided as much as possible. If there is a window sill, in order to prevent the accumulation of dust and facilitate cleaning, it should be made as inclined as possible; (9) The doors on both sides of the delivery box must be interlocked and airtight, easy to clean; (10) The color of a clean room should be elegant, soft and harmonious. In addition, the light reflection coefficient of the decoration materials on each surface of the room is 0.6-0. 8 for suspended ceilings and walls, and 0.15-0. 35 for the ground. (11) The coatings for walls and ceilings in clean rooms should be flame-retardant, anti-crack, corrosion-resistant, wear-resistant, and have a smooth surface. They should be water-absorbent and non-degradable and mold-free paint; (12) If the walls and ceiling surfaces of the clean room are plastered, advanced plastering standards should be adopted, and the curing time should be sufficient; materials that deform, crack, mold, or pulverize due to heat and humidity should not be used. After plastering, the paint surface layer should be brushed, and the paint should be inflammable, non-cracking, resistant to cleaning, smooth surface, and not easy to absorb water and deteriorate.

  • Relevant requirements for clean room engineering

    Relevant requirements for clean room engineering

    Sep 25, 2020

    The decoration cost of the clean room project is relatively high. The factory spends such a high cost, and the requirements for it are naturally high. First of all, when selecting the project site, it is necessary to select an area with no air pollution, and there will be no large amount of dust particles around. Such an environment can reduce the load of the clean room air conditioning system and reduce the cost of clean room operation. Because the factory has strict requirements on the cleanliness of the clean room project, which is specifically reflected in the amount of bacteria and dust in the air. The smaller the content, the lower the clean room level and the more difficult the decoration. If the clean room project wants to meet the relevant grade requirements, it is necessary to do a good job in the design and installation of the air conditioning control system, and do a good job in the quality control of the decoration materials to reduce the generation of harmful gases in the decoration. The air conditioning system can control the temperature, humidity and pressure in the clean room through the frequency and size of the air change. At the same time, it is ensured that the content of various bacteria and dust in the air can meet the requirements of clean room engineering. At present, according to different industries, different clean room grades, there will be slight differences in engineering requirements. For example, ordinary clean room engineering needs to comply with the requirements of GB50073-2001, the decoration requirements of hospitals for clean rooms should comply with GB50333-2002, and pharmaceutical factories should comply with the regulations of GB50457-2008. In order to meet the various requirements in the clean room project, the decoration company needs to have very professional decoration technology and professional and advanced decoration equipment. They must submit relevant qualifications and certificates, and apply for the corresponding decoration qualifications in order to obtain the qualifications for the renovation of the solution room. At the same time, in daily life, it is necessary to learn more advanced decoration techniques in the industry to improve the skills of decoration personnel. Specialize in the clean room industry for many years. WONZONE
