Clean and dust-free workshop is a very clean workshop environment. All the workers in the air purification project, including all the machinery and equipment, have to meet a certain degree of standards, clean and tidy, to ensure the quality requirements of the production products. Only the dust free workshop can guarantee the quality and function of the chip.
What is the reason for the unqualified work in clean and dust-free workshop?
1. the design of the project is unreasonable
This phenomenon is relatively rare, mainly in the construction of some small clean rooms that require less cleanliness. Now the competition for purification is fierce. Some construction units have offered lower quotations for bidding in order to get the project.
2. replacing high-grade products with low-grade products
In the application of the clean room high efficiency filter, the state stipulates that the air purification treatment of 100 thousand levels of cleanliness or above 100 thousand levels should adopt the three stage filter of the first effect, the medium effect and the high efficiency filter.
3. air supply pipe or filter is not well sealed
This phenomenon is caused by the rough construction, in the acceptance of the same system will show a room or part of the same system is not qualified. The improvement method is that the air duct is leaked by leakage test. The filter uses particle counter to scan the section, sealing and installation frame of the filter to find out the leakage position and carefully seal it.
