Clean room manufacturer's clean room design

Shixu Electromechanical Equipment Co., Ltd. is located in Suzhou, Jiangsu Province, and is a well-known manufacturer of clean rooms. The purification work shed controls the main production processes in a small environment, making it the best choice for clean room design. Clean rooms are widely used in industries such as electronics, precision instrument processing, pharmaceuticals, medical, and food, and are essential clean equipment for these industries.

Suzhou Shixu Electromechanical Equipment Co., LtdThe clean work sheds produced can be roughly divided into the following types: ordinary curtain type, glass structure type, steel plate structure type, built-in air conditioning type, module combination type, anti-static type, and built-in air shower type, etc., which can be designed and constructed according to specific customer requirements.

As a professional cleanroom manufacturer, attention should be paid when designing cleanroomsThe issue of dust generation:


The amount of dust generated in the clean room from the equipment can be considered to be discharged through local exhaust, without flowing into the room; The amount of dust generated during the transportation of products, materials, etc. is generally negligible compared to the amount of dust generated by the human body; Due to the application of metal half walls (color steel sandwich panels), the dust generated from the building surface is also minimal, generally accounting for10%The dust mainly comes from people, accounting for90%about. In terms of human hair dust, due to the improvement of clothing materials and styles, the fine amount of hair dust has also been continuously reducedAMaterial: Cotton has a high dust emission rate, followed by cotton, Dacron, anti-static pure polyester, and nylonBStyle: Large hanging type with high dust emission, followed by upper and lower split type, and less full cover type;


Activity: The amount of dust generated during movement generally reaches the static time3-7Double;


Cleaning: The amount of dust generated by washing with solvent is reduced to one-fifth of that of cleaning with regular water. The amount of dust generated on the surface of indoor maintenance structures is based on the ground, approximately corresponding to8The surface dust emission per square meter of ground is equivalent to that of a stationary person.


　Attention should be paid to the design of clean roomsThe issue of bacterial growth


Pollution generated by staff:
　1）Skin: Humans typically complete a complete skin replacement every four days, with a shedding rate of approximately per minute1000Skin flakes (average size of)30*60*3Microns)

2）Hair: Human hair (diameter approximately)50~100The micrometer has been continuously shedding.
　3）Saliva: including sodium, enzymes, salt, potassium, chloride, and food particles.

4）Daily clothing: particles, fibers, silica, cellulose, various chemicals, and * *.
　5）Human stillness and sitting will produce every minute10000A greater than0.3Micro sized particles.
6）When humans make movements on their head and torso, they will produce every minute1000000A greater than0.3Micro sized particles.

　7）Human beings0.9m/sThe speed of walking will generate per minute5000000A greater than0.3Micro sized particles.


Analyzing foreign experimental data, it can be concluded that:（1）When the staff in the clean room are wearing sterile clothes, the bacterial count at rest is generally10-300a/min.The amount of bacteria produced during normal physical activity is150-1000a/min.The bacterial count when walking fast is900-2500a/min.People

（2）Coughing once is usually70~700a/ min.A person sneezing once is usually4000~62000a/ min.People

（3）Bacterial count when wearing regular clothes3300~62000a/ min.person
（4）No mask bacterial count:There is a bacterial count on masks1:7~1:14　
（5）Bacterial count: Dust count1:500~1:1000According to domestic examples:
（6）Personnel's bacterial count during surgery 878a/ min.Therefore, it is known that the static bacterial count of personnel wearing sterile clothes in clean rooms generally does not exceed300a/ min.Human, dynamic bacterial count generally does not exceed1000a/ min/People, using this as a reference for clean room design.
