Control and minimize the possible contamination of the cleanroom is the key to the normal operation of the cleanroom, so how to do a good job of the daily maintenance and management of the cleanroom?

1. The main content of the daily management of the cleanroom

(1) Ensure the cleanliness level required by the cleanroom:For the cleanroom, it is required to enter the cleanroom air is clean, to ensure that the dust content of the air into the room is lower than the dust content of the cleanliness regulations. The amount of dust value;the requirement to enter the cleanroom of people and objects after the necessary purification process to minimize the amount of dust with people and objects.

The main measures to ensure the cleanliness of the cleanroom are:measures to ensure that people are clean, to ensure the purification of the materials entering the cleanroom, to ensure that the air entering the cleanroom is clean, to ensure that the clean air conditioning system air supply, to ensure that the positive static pressure in the cleanroom according to the requirements of the value of the cleanroom, to minimize the amount of dust produced in the cleanroom, to ensure that the regular cleaning of the cleanroom, to ensure that the cleanroom is clean, to ensure that the cleanroom is clean, and to ensure that the cleanroom is clean. Ensure regular cleaning of the cleanroom.

(2) Ensure that the indoor air required by the cleanroom State parameters:The air state parameters of the cleanroom are determined according to the requirements of a certain process conditions or a certain work requirements, so in addition to ensuring the cleanliness of the cleanroom, but also need to meet the requirements of the indoor air temperature and humidity.

In the cleanroom, if the air temperature is too low, it is not conducive to the normal conduct of work;on the contrary, if the temperature is too high, it will make the indoor staff to produce too much sweat, sweat evaporates into the air as tiny particles, which will increase the number of particles in the air in the cleanroom, so that the level of cleanliness is decreased. The cleanliness level will be reduced, and the requirements of the process conditions cannot be guaranteed.

(3) Formulate strict management rules and regulations:Cleanroom The daily management process should develop a strict and effective system, and should be strictly and seriously implemented. Cleanroom operation regulations and management system includes daily attention to matters (provisions for entry into the cleanroom entry, registration system for personnel entering the cleanroom, registration system for personnel entering the room, the provisions of personnel in and out of the provisions of the cleanroom, the provisions of the items entering the cleanroom, the selection of utensils and equipment in the cleanroom and the management system, the provisions of special clothing and management system of the cleanroom, the cleanroom hygiene and safety systems, cleanroom Staff education and training system and health measures and other regulations.

2. 洁净室日常管理采取的主要措施

(1) Measures of the Guarantor's Net:The specific measures to ensure that people are clean mainly include washing, changing shoes and clothes and air blowing three aspects.

①Washing:Wash your hands and face with water, and your entire body if necessary, to remove temporary epidermal The body should be washed with water to remove temporary epidermal adhesions and accumulated body surface discharges. Industrial cleanrooms generally require hand and face washing. The aseptic cleanroom is more demanding, generally require a bath.

②Changing Clothes and Shoes:In order to reduce the pollutants brought into the cleanroom from the outdoors, it is generally required that Personnel entering the cleanroom to change clothes and shoes. Change out of shoes and clothes and put on cleanroom overalls or sterile room overalls to enter the cleanroom. In this way, the outdoor dust or pollutants attached to the clothes and shoes will not be brought into the cleanroom with the personnel.

For Aseptic IndustryAlso required to take off all the outwear and underwear, and then replaced with clothing suitable for cleanroom or aseptic room work. For clean work clothes, not only requires its surface clean and easy to remove pollutants, but also to be able to filter the dust bacteria emitted by the human body to stay on the side of the human body, but also need to ensure that it is not easy to produce static electricity.

③Air blowing:Air blowing shower is to use high-speed clean air to sweep the whole body clothing and exposed surface of the The air shower is a high-velocity, clean air blast that sweeps away temporary adhesions from clothing and exposed surfaces.

(2) Decontamination of materials entering the cleanroom:Into the Materials in the cleanroom should be cleaned and decontaminated before being transported into the cleanroom in order to reduce the amount of dust generated by the materials in the cleanroom. Small items entering the cleanroom are generally entered through the transfer window between the cleanroom and the outer corridor or between the cleanroom and the cleanroom (neighboring rooms with different cleanliness levels). For the electric oven, oven end from the sterile area open the door, input materials after a period of sterilization and then open the door from the aseptic room to take out the other end of the oven.

Large objects entering the cleanroom are first purified in the general environment by initial vacuuming with a vacuum cleaner, and then further processed in the cleanroom with a cleanroom vacuum cleaner or wiping method. Small objects entering the cleanroom should first be wiped and cleaned in the quasi-cleanroom, and then loaded into the transportation box and then sent into the room. Personal belongings are not allowed to be brought into the cleanroom, the provisions of the cleanroom duty common items can be brought into the room.

(3) Ensure that the air entering the cleanroom Dust content is lower than the value of dust content specified by cleanliness:Cleanroom air is not used as a cleanroom. 14px">Clean air conditioning system in operation, the use of all levels of air filters must be intact and no leakage. In order to prevent the air supply system to bring in outdoor pollution dust particles, must be used in the system of coarse, medium and end air filter leakage inspection on a regular basis.

(4) Ensure that the clean air conditioning system's air supply:Guaranteed Clean air conditioning system air supply is required to ensure that the number of air changes in the cleanroom to meet the needs of indoor airflow organization. Clean air conditioning system normal operation, the system should be regularly measured air supply volume, measurement points can be selected in the fan inlet (outlet) air inlet and outlet. Clean air conditioning system and cleanroom in operation should be regularly checked at all levels of air filter air resistance and the amount of dust, or regular use of differential pressure meter for testing, so that the system's air supply is basically unchanged.

(5) Ensure that the positive static pressure in the cleanroom is maintained according to the requirements. value:Cleanroom and clean air conditioning system in operation, should pay attention to frequent inspection, maintenance, adjustment and repair of the system in the residual pressure valve, as well as pressure sensors, transmitters, regulators and actuators, so that it is in a normal state of operation, to maintain the indoor requirements of positive static pressure value.

(6) Minimize the amount of dust produced in the cleanroom:In a cleanroom, there are two factors that generate dust:the first is the operation of the equipment, and the second is the activity of the operator. Therefore, the amount of dust produced in the cleanroom should be controlled from these two aspects.

The cleanliness of a cleanroom directly affects the quality of the product and the quality of the cleanroom. The cleanliness of the cleanroom directly affects the quality of the products and the safe operation, service life and efficiency of the cleanroom, and also has a direct impact on the operating costs. Strict management and control of the cleanroom needs to be implemented on a daily basis to ensure the cleanliness of the cleanroom environment, to prevent contamination, so as to ensure the normal operation of the cleanroom, in order to continue to produce stable, high-quality products!
