The building structure In construction, we only need to pay attention to: For the masonry construction within the scope of clean room, the quality control grade should meet the A level requirement of the current national standard "Masonry Engineering Construction Quality Acceptance Code" GB50203 Article 3.0.10. In the construction of steel structure in high and large clean space, the dimension deviation of components should be strictly controlled. For the joints that do not require crevice in design, we should be sealed with sealing materials after the qualified acceptance of the main body of the steel structure. The anticorrosive and fireproof coatings on the surface of steel structures shall not be leaked to paint. Architectural decoration Architectural decoration is divided into six aspects (i.e. floor, wall, ceiling, corner,clean room door and window, gap sealing) to achieve the clean requirements. First of all, from the material point of view, in addition to meeting the requirements of heat insulation, sound insulation, vibration protection, insect prevention, anti-corrosion, fire prevention, anti-static and other requirements, the clean room construction materials should also ensure that the air tightness of clean rooms is well and decorative surfaces do not produce, absorb, and accumulate dust, and it should be easy to clean. Secondly, the clean room construction materials project should implement the closed and clean management of the construction site, and effective measures should be taken to prevent dust diffusion when dust operation is carried out in the clean construction area.
1. Cleaning of the clean room should be done before the end of the day and after the end of the process operation. 2. Cleaning should be carried out in the operation of clean room air conditioning system. 3. After cleaning, the air-conditioning system will continue to operate until the required cleanliness level is restored, generally not less than the self-cleaning time of the clean room. 4. Sweeping mops and rags should not be made of easy-to-remove fabrics. They can generally be made of long-fibre materials or polyurethane sponges. 5. In order to prevent cross-contamination, clean rooms with different cleanliness levels should have their own special cleaning supplies, and garbage should be put into dustproof bags (plastic bags) and taken out. 6. Clean room cleaning detergent can be prepared by adding 30 g neutral residual liquid detergent per liter of water. 7. Purified water should be used instead of tap water for cleaning high-level clean rooms. Disinfectants used should be replaced regularly to prevent microorganisms from developing resistance to antibiotics. 8. When large objects are moved into a clean room, they should be cleaned initially by vacuum cleaner in general environment, and then further treated by vacuum cleaner or wiping method in quasi-clean room. During the period when the clean room purification system stops operating, large objects are not allowed to be moved into the clean room. 9. Small items that need to be brought into the clean room should be wiped and cleaned in the quasi-clean room first, and then brought in through the transfer window or into the handling box. 10. Fire fighting equipment, safety doors and safety passages in the clean room should be clearly marked, and staff members should be familiar with their locations. Safety doors must be open at any time, and no debris should be piled up in safety passages. Safety fire protection facilities should be checked regularly. 11. When a fire alarm occurs in a clean room, an alarm should be issued immediately, the fan and all equipment in the clean room should be closed, and the power supply and flammable gas access should be cut off. (System and fire alarm equipped with fire valve or fire switch will automatically shut down the fan and need manual reset afterwards.

Clean room parameters are a more complicated issue. With the advancement of technology, more and more industries apply clean rooms. Clean rooms in different industries have different parameters, so there are more and more technical parameters. The microelectronics industry has higher requirements for the concentration of air-floating particles; the pharmaceutical industry has higher requirements for the concentration of air-floating bacteria; the precision measurement and precision processing industries have higher requirements for temperature and vibration. In view of the above situation, the technical parameters of the clean room can be divided into two categories: basic parameters and special parameters. Second, the basic parameters of the clean room 1. Cleanliness Cleanliness is the most important and basic technical indicator of a clean room, and its unit is: the number of particles with a particle size not less than a certain scale per unit volume of air. The microelectronics industry has the highest requirements for cleanliness, followed by the optoelectronics industry. 2. Microbial concentration Microbial concentration is another important technical indicator of a clean room. Its unit is: the number of microorganisms per unit volume of air. The bioengineering industry has the highest requirements for microbial concentration, followed by the medical, pharmaceutical, food, beverage, and cosmetic industries. There are many types of microorganisms, including viruses, bacteria, fungi, algae, spores, pollen, and mites. Microorganisms in the air are part of the airborne particles, to be precise the more harmful part. Usually the concentration of bacteria in the air is measured. 3 .temperature Temperature is the basic working condition. Almost all clean rooms have clear requirements for temperature. Temperature will affect the scale of the object, thereby affecting the accuracy of processing, so precision processing has quite strict requirements on temperature. Temperature will affect the parameters of the instrument, resulting in measurement errors, so precision measuring instruments have higher requirements for temperature. 4. Humidity Humidity is also a basic working condition. Almost all clean rooms have clear requirements for humidity. Excessive humidity will cause chemical reactions of many substances, which will affect the quality of products, and even cause equipment failure and product scrap. If the humidity is too low, many substances will be dehydrated and deformed and lose their original functions. 5. Wind speed and volume Adequate wind speed and air volume are the guarantee of cleanliness. Excessive wind speed and air volume not only waste energy, but sometimes affect normal work. 6. Air pressure and pressure difference Normal air pressure is the basic condition for normal work. The necessary pressure differe...

It is equipped with double-layer hollow tempered windows, domestic well-known brand stainless steel handle door locks, door closers, hinges (or customer-specified brand accessories). When the door cover is connected with the machine-made color steel plate wall, the double-fabric frame assembly connection method is adopted. When the door cover is connected with the hand-made color steel plate wall, the independent frame aluminum connection method is adopted. All the connections are specially designed and do not need to be repaired separately. The clean room steel doors and clean room glass windows are the company's summary of the construction and production practices over the years, and have widely adopted a large number of opinions and suggestions from other construction companies and users. The materials and production process equipment have been improved many times. Basically finalized, and recognized by well-known experts in the purification, environmental protection, construction, decoration and other industries, the successful adoption of the clean room steel door and clean room glass window plays a key role in the upgrade of the clean room and changes the original The solidity, air tightness, aesthetics, durability, corrosion resistance and other undesirable defects.
Treatment of gaps between clean room doors and windows:Generally speaking, clean room doors and windows have three types of structural gaps. The first type is the assembly and splicing gap between the door and the clean room door opening; the second type is the overlap gap between the door and the opening fan; the third type is the installation gap between the glass or other core boards. Generally speaking, the air leakage of the clean room door is nothing more than the problem caused by the above-mentioned three kinds of gaps. Among the three structural gaps, the first and third types are fixed gaps, and the second type is movable gaps. 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. Treatment of fixed gaps:The installed gaps examined are not only relatively small in the number of doors and windows in each clean room today, 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 airtight clean room doors and windows, but also for the general clean room door structure. Due to the strong 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. Basically ensure the air tightness of this type of gap; the second type of fixed gap is the installation gap of glass or other core boards. The number of gaps in the door of an orange clean room is relatively small, but the structural gaps in the one chamber are often the main part. Especially for the outer universe, they are exposed to the atmosphere and affected by the outdoor climate. It must be handled carefully. On the one hand, it is necessary to minimize the installation gap of the core strip glass, and on the other hand, it is necessary to carefully choose the fortification structure. Handle the movement gap:How to overlap the opening fan and frame material of the clean room door is the key to the design of the clean room door seal. The gap at the lap joint is different from the fixed gap. Because the movable fan needs to be opened, the wood can take 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 in 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 gap around the door ...
