How to do a common dust-free workshop?

Dust-free workshop should pay attention to air purification system, floor and wall materials, personnel entrance and exit, air pressure control, temperature and humidity control, periodic testing and verification, etc.

1 air purification system

The core of clean workshop is air purification system, including air filter, air supply system and exhaust system. The air filter can effectively filter the particles in the air, the air supply system sends the filtered air to the workshop, and the exhaust system discharges the pollutants in the workshop.

2, the ground and wall materials

The floors and walls of the dust-free workshop need to be made of smooth and easy-to-clean materials, such as epoxy floor and stainless steel plate, for cleaning and disinfection.

3. Personnel entrances and exits

Air locks need to be set at the personnel entrance and exit of dust-free production workshop to prevent external pollutants from entering the workshop. The airlock usually consists of two doors, and only one door can be opened at the same time to maintain positive pressure in the workshop.

4. Air pressure control

Dust-free workshop needs to maintain a certain positive pressure to prevent outside air from entering the workshop. By controlling the air volume of air supply system and exhaust system, the air pressure can be controlled.

5. Temperature and humidity control

The temperature and humidity of dust-free workshop should be kept within a certain range to meet the requirements of production technology. Temperature and humidity can usually be controlled by air conditioning system and humidification system.

6, regular testing and verification

Dust-free production workshops need regular air quality testing and verification to ensure the cleanliness of the workshops meets the requirements. It can be detected by air sampling and microbial detection.
