　　1、Cleanliness environments vary.
A dust-free workshop can ensure and maintain cleanliness.During the filtration process,in addition to using primary and medium efficiency filters,high-efficiency filtration is also carried out to disinfect live microorganisms in the air,ensuring the cleanliness of the air in the workshop;The air supply volume in a cleanroom is much larger than that in a regular workshop.Generally,a regular workshop has 8-10 air changes per hour,while a one-way flow cleanroom has 400-600 air changes per hour;The cleanroom must always maintain a positive pressure state to prevent external pollutants from entering the clean area,which ordinary workshops do not pay attention to.
2、Good insulation and moisture retention performance.
Ordinary workshops only need to meet the requirements of product production and processing,and there are no particularly strict requirements for structural design.In terms of material selection for the board,it does not have the rigor of a dust-free workshop.The materials used to build a dust-free workshop are very particular,as they not only have good insulation and heat preservation functions,but also can maintain humidity.
3、Personnel pollution control varies.
The major feature of a dust-free workshop is the separation of clean and dirty materials,with dedicated pathways for personnel and items to avoid cross contamination.After that,it is necessary to carry out blowing and spraying to remove pollutants attached to personnel and objects,avoiding bringing pollutants to the clean area and affecting the purification effect of the purification project.
4、Strong load-bearing capacity.
The load-bearing performance of the ceiling in a cleanroom is stronger and more resistant to bending and compression than that of a regular workshop.
5、Install filtered air supply equipment.
The air supply equipment is made of high-quality materials,which are beautiful and can filter out many impurities in the air,and are easy to clean.
6、Floor material selection.
The floor of a cleanroom also requires a lot of attention compared to a regular workshop,including choosing anti-static materials and wear-resistant plastic flooring.Cleanroom can play a great advantage in industrial production and ensure the quality of air,thereby producing high-quality products.Before building a dust-free workshop,it is particularly important to choose high-quality manufacturers who can scientifically design for different fields to ensure that the final solution meets the overall production needs.
