Experts talk about cleaning methods for clean benches

We can build clean rooms with high cleanliness, but we often cannot ensure the cleanliness of these cleanrooms is up to standard. I have been invited to many factories for on-site diagnosis. I have found that the equipment in many factories is quite advanced, but the cleanliness of the cleanrooms of these factories has never reached the standard after passing the airless, static cleanliness test. Obviously the problem lies with people. I saw at the scene that workers did not change clothes in accordance with the regulations. They did not do the required actions in the air shower, and even some female employees entered the clean room after makeup. It is conceivable that how cleanliness can be achieved if the largest source of pollution in the cleanroom, human activities, is not regulated and controlled?

Pay attention to the relevant methods of purchasing clean bench

In the domestic market, the ultra-clean benches are generally classified into: economical high-efficiency air filters adopting the national standard, the indicators are lower than the international standards, and the appearance is also unsatisfactory; the fans are generally made of domestically-made ordinary fans, and have good performance when they start working. The performance is not guaranteed for a long time; in order to reduce the cost, no external air filter is used; the control system is simple and the appearance is not good.

Ordinary all-imported or multi-use foreign materials and foreign technologies in the domestic production of air filters, performance close to imported products; fans using mid-range products, but also useful Sino-foreign joint venture fans, more reliable, but most are not for the clean bench Designed for special needs, so the prolonged use of uneven stroke volume is its characteristic; comprehensive performance is better, but the control system is relatively simple, glass doors are generally manual. High-grade, all-imported high-end products or original filter; fans use imported fans designed according to the characteristics of the use of clean bench; the main performance is higher than the ordinary type; the control system is optimized for the user: glass door Most of them are driven by electric motors. There are sensors inside the box that can reflect the working conditions of the filters to improve the reliability of the products. A few products use embedded control systems. Do not simply focus on the purchase of ultra-clean benches at ultra-clean benches. Quoting is an important factor.

However, if you consider that the clean bench is a long-term equipment, the maintenance and maintenance costs are also high. Here, the clean bench has a prominent feature. Its air filter is a depleting product. During use, dust on the filter surface will accumulate, leading to increased wind resistance. Finally, the filter will be scrapped and the system will fail. Once such a phenomenon occurs, high-end products will immediately warn you, but you cannot be sure whether the same problem occurs in middle- and low-grade products. Do you know what money is being spent on what to buy? Changing the filter is both troublesome and costly. Because of this, most mid- to high-end products use prefilters to extend the filter's service life. Most low-end products are only symbolic pieces of cloth.

Pay attention to the cleaning and disinfection of clean benches

The clean bench is a special kind of worktable. Imported products will use a lot of space to tell you how to clean and disinfect. Better clean benches will have many accessories, most of which are related to cleaning and disinfection. The optional clean bench should at least be equipped with a UV lamp for disinfection. You may wish to ask the supplier what they have done for the customer's cleaning and disinfection. If you find that a certain product is not suitable for cleaning, you do not need to consider it. It may have good performance and low price, but it will be very inconvenient for long-term use.
