Particle quantity regulations for the division standard of clean room engineering


The dust-free purification level of the dust-free workshop project is mainly based on the number of particles in each cubic meter of air whose diameter is greater than the classification standard. In other words, the so-called dust-free is not 100% without a little dust, but is controlled in a very small amount of units. Of course, the particles that meet the dust standard in this standard are already relatively small compared to our common dust, but for optical structures, even a little dust will have a very large negative impact, so in the production of optical structure products , Purification of dust-free workshop is an inevitable requirement.

Then the relevant knowledge points about the clean room engineering are mainly as follows: no one who has been appointed can perform discerning operations. Operators must complete the work in accordance with the work instructions or machine operating instructions. The assignment of work is determined by the cadres who are longer than the length according to the needs of the work. Changes in operation methods or special skills operations must be performed only after approval by supervisors. Operators need to do a self-check of the line station. Operators need to check the previous station, and all operators must understand the content of the previous station and the next station. The operator must complete the output value according to the rules to ensure the efficiency of the operation. When an abnormality is found in the operation, it must be reported to the cadres above the lengthen for timely disposal. When the operator finds that the personal work materials are not working, he needs to report to the material staff or the elongation or picking staff one hour in advance, and he cannot take the materials to the material racks.
