1. treatment of gaps in clean room doors and windowsgenerally 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 lap gap between the door and the opening fan; the third category 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 are movable gaps. They are different in nature and their proportions on clean room doors and windows are also different. Therefore, the airtight measures adopted for the airtightness of clean room doors and windows are not exactly the same, which is also an important step in the dust-free evolution project.

A: treatment of fixed gaps The installation gaps checked 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. To ensure the air tightness of this type of gap, the second type of fixed gap is the installation gap of the 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.

B: handling of movable gaps 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 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, while 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.

The threshold of the clean room must be specially constructed according to different requirements of transportation and pedestrians. three of the four sides of the single-leaf open clean room door's gaps need to be treated differently, and the center gap of the double-leaf clean room door has a special structure. Therefore, the sealing treatment of movable gaps in the design of clean room doors is a more prominent problem. The size and form of the slot where the opening fan and the frame material overlap each other are important issues that must be paid attention to in the design of the movable gap seal.

four factors such as village bureau, frame, hardware, airtight strip and its mode of action should be considered comprehensively to make them coordinate with each other in terms of structural failure and stress state to achieve the purpose of sealing. it should be particularly pointed out that the clean room doorleaf is larger and heavier than the window sash, and the force is much greater when the seal is compressed, and it is always open and closed in normal times. Therefore, it is necessary to control the droop of the clean room door leaf and ensure the rigidity of the clean room door leaf. Let's focus on the issue of hardware selection.

  2. The gap sealing of the door leaf of the side-opening clean room The side-opening closed clean room door is the most widely used clean room door type in the clean room. it is usually used for passage or transportation. it is very convenient for emergency evacuation in case of fire.
