The slot-sealed flat-closed clean room door of the door and fan of the open clean room is the most commonly used type of clean room door in the clean workshop. It is usually used for traffic or transportation, and is very convenient for emergency evacuation in case of fire, which is very convenient. The elastic material of the forming section is usually chosen as the sealing strip to fix and seal at the state of the seam. The opening width of common sliding doors clean room is less than 1800 mm in double inner clean room doors and 2100 mm in double outer clean room doors, and the height of the opening is in the range of less than 2400 mm. The setting of the sealing strip. In the case of frequent opening and closing of the doors and fans of clean rooms, it excepts the following situations：some outside clean rooms door and windows, which may install the sealing strips on the doors and fans of clean rooms to avoid the transportation of the heavy equipment , or some doors of inner clean rooms are not allowed to set the doors of clean rooms on the ground because of workshop transportation, and only suspended sweeping can be installed at the bottom of the doors and fans of clean rooms close to the ground. In general, in order to avoid the hand model, foot step or car collision as far as possible, and less affected by the operation and transportation, the small section forming sealing strips of several millimeters in length and width is laid on the concealed groove part of the door lift of the clean room, and then tightened by the closure of the door fan of the clean room. The sealing strip should be laid continuously along the periphery of the movable gap in order to form a trapped and closed ring sealing line after the door of the clean room closes. When the sealing strip is set at the door building and the door fan of the clean room respectively, it is necessary to pay attention to the good connection of the pottery and minimize the small gap between the airtight strip and the crack of the clean room doors and windows. Welcome to choose and buy the clean room equipment produced by Wonzone clean room doors and windows factory.
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...
