What is the dust reduction degree of one million in the purification workshop

The amount of dust reduction is a measure of whether the purification workshop is normal or not. If it is too high, it proves that there are certain environmental problems in the workshop. What is the dust reduction degree of the million level purification workshop?

Generally, the dust reduction degree of a million level purification workshop shall not exceed one million. The dust reduction amount of the purification workshop refers to the amount of micro dust particles floating in the air in the area of limited indoor space. It usually refers to the maximum allowable dust quantity / square unit under the required cleanliness level. Generally, 100000 dust-free production workshops are 100000 dust particles. And the dust particles are > 0.5um. The amount of falling (falling) dust is used to detect the cleanliness of dust-free production workshop, which should be detected by particle counting (dust particle meter).

In general, the dust reduction amount of dust-free production workshop is different with different cleanliness. It is also endangered by the construction or maintenance of dust-free production workshop and the maintenance in the whole process of application. Therefore, the dust-free production workshop with high dust reduction requirements for the working environment must be measured accurately, and the accurate measurement requires a long cycle time. The universal accurate measurement cycle time is measured accurately once every two months, and it should be recorded unremittingly. If it is a temporary application of dust-free production workshop, it is another matter. The measurement specification and measurement method of dust fall in the actual purification workshop have influence: the national standard used at this stage is the national industrial standard environmental quality of the people's Republic of China - net weight measurement method of dust fall, 1994 edition.

If air anion is selected to carry out dust reduction in the production workshop technically, the amount of air anion is 100000 / m3, and the necessary time is not easy to be long. For example, the reasonable total area of air anion equipment is 25 square meters. If the dust reduction time of fine dust particles in 25 square meters of indoor space will not exceed 1 hour at most. If the total area is higher, you can choose to increase the total number of equipment again, If you choose other air filtration products, there will be no clear and detailed output power.
