Cleanroom ESD suits also have a retirement age, please do not use them indefinitely.
When customers consult, they often ask: If the dust-free clothes that have been used for a long time have no obvious damage on the outside, can they still be used? On the contrary, if the dust-free clothes that have not been used for a long time are obviously damaged due to various reasons, do they need to be scrapped? If the cleanroom suit is mended, will it be saved from scrapping?
These are common questions that you may have encountered or are currently encountering. How should you answer them?
Dust-free clothing has a certain service life, and it is difficult for us to define the specific service life based on the number of cleanings. For this reason, as a professional dust-free purification and cleaning company, our technicians will test the performance of the dust-free clothes after each cleaning, such as anti-static performance and cleanliness, and issue a test report. When the performance of a batch of dust-free clothes shows obvious attenuation, technicians will notify the manufacturer in the form of a written report that these unqualified dust-free clothes should be scrapped.
For dust-free clothing that has not been purchased for a long time but is obviously damaged, it needs to be repaired by the dust-free clothing manufacturer in accordance with the sewing requirements specified by the dust-free clothing. At the same time, if it passes the performance test, it can continue to be used.
Generally speaking, after professional dust-free cleaning, a 5MM grid dust-free suit can be cleaned about 50 times, and a 5MM stripe dust-free suit can be cleaned about 30 times. Assuming that each employee uses two sets alternately, and the cleaning frequency is one week, the use time of 5MM grid is about two years, while the use time of 5MM stripe is about one year.
As for the "retirement" time of dust-free clothes, technicians must strictly test it. If they find that aging clothes are found, they must not be merciful to avoid delaying production and causing losses.
