Use matters and maintenance of 100,000-level dust-free workshop


1. The biggest pollution sources of the 100,000-level dust-free workshop in operation are people and articles entering the dust-free workshop, as well as dust particles generated during the production process.

Second, the reasonable flow of people and logistics is of great significance to maintain the cleanliness of the room. The staff bathed and changed clothes before entering the 100,000-level dust-free workshop, and their clothes conformed to the standards of clean management standards. Before the materials enter the 100,000-level dust-free workshop, the packaging is blown. The changed materials meet the clean room standards. By doing so, the cleanliness of the clean room can be maintained.

3. The operators in Class 100,000 cleanrooms must work strictly in accordance with the operating rules of cleanrooms. The doors and windows of the 100,000-level clean room should be closed at any time. There should be a buffer zone for the transfer of people and items between the clean room and the non-clean room, and there should be air bath equipment to prevent the convection of the air flow, which is not related to production The personnel cannot enter the 100,000-level dust-free workshop.

The number of air changes in the 100,000-level dust-free workshop and the air supply of the air-conditioning purification system are the main internal reasons for maintaining the positive pressure and cleanliness of the clean room, but it is restricted by the final resistance of the filters at all levels in the purification system.

5. The equipment in the 100,000-level dust-free workshop requires regular, regular, and regular cleaning and maintenance, and whether the materials and cleaning liquids used in cleaning meet the regulations of clean room management.

6. Class 100,000 dust-free workshops should regularly test the dust particle concentration, wind speed from the air outlet, temperature and humidity, etc., and make maintenance plans based on the measurement results. The primary, intermediate, and high-efficiency filters in the air-conditioning purification system should be replaced regularly according to changes in wind speed and changes in indoor positive pressure.
