Cleaning and Sterilization in Dust-free Purification Project

Jan 25, 2019

Clean environment maintenance is very important in dust-free purification project. Cleaning usually takes place after the end of the production process. If it is necessary to clean before production, the process production must be started after the start-up time of the purification air-conditioning system meets the requirements of cleanliness. In order to prevent cross-contamination, cleaning facilities should be dedicated to different product characteristics, process requirements and cleanliness levels.


Cleaning tools used in dust-free purification projects generally use centralized fixed and portable vacuum cleaning equipment. If you do not meet the above requirements, you can also use non-fiber materials such as mercerized towels, nylon cloth for wiping, usually once or several times a day. Workbenches and tools are usually cleaned once a day; walls and floors are cleaned once a week and once a month for 10,000 to 100,000 plants. Cleaning air conditioning system should be cleaned 1 to 2 times a year and entrusted to special cleaning personnel.


In addition to controlling the number of biological or abiotic particles in the air fed into the dust-free purification project, disinfection treatment should also be carried out on the surfaces of indoor appliances, floors, walls and panels. Sterilization and sterilization measures must be taken in operation and management to reduce the survival and multiplication of microorganisms in clean rooms.www.wxrfcleanroom.com
