What are the requirements for the installation of clean room construction air duct system?

Clean room is no stranger to us. The environmental requirements of precision machinery industry and semiconductor industry have promoted the rapid development of clean room technology. This time, what are the requirements for the installation of clean room construction air duct system? If you don't know, please join Xiaobian to see the following content:

1. The air duct of purified air conditioning system shall be installed when the ground at the installation site has been constructed and indoor dust-proof measures have been taken.

2. After the air duct can be installed through the information system analysis, the tightness test of the enterprise management control system shall be carried out, and the air duct insulation and other processes can be continuously developed after passing the acceptance.

3. The hangers and supports of the air duct system shall be more firmly connected with the building envelope of China. When fixing with expansion bolts, relevant national data and technical management documents shall be observed. The supports and hangers shall be analyzed and studied, and the anti-corrosion technology can be treated.

4. Installation requirements of accessories: before installation in place, it must be wiped clean to avoid oil and dust pollution. During or after construction, the air duct orifice shall be sealed; The flange gasket shall be made of materials that do not produce dust, are not easy to aging, are impermeable and elastic; The thickness of gasket shall be 5 - 8mm; Flange gaskets shall not be butt jointed with straight seam. It is forbidden to use paint gasket and sealant together, and safe and reliable sealing measures shall be taken. When the air pipe passes through the ceiling and partition wall of the clean room, it is forbidden to use other types of pipes to pass through the air pipe.
