Clean industry course develops the summary for years, clean technology and equipment reached a more mature level, but still put in a few problems, be in especially home, of major clean room clean degree not quite stable from beginning to end, or design level can be reached below the static state, and a short of falls in trends. Outside the goes up besides oneself design problem that causes this kind of condition actually, main reason is the small pollution inside clean area. The pad of ground sticking dirt that British Dycem company produces offerred new thinking and way to solve this one problem.

Clean industry passes old development, clean technology and equipment reached a more mature level, but still put in a few problems, be in especially home, of major clean room clean degree not quite stable from beginning to end, or design level can be reached below the static state, and a short of falls in trends. The main reason that causes this kind of condition actually is the small pollution inside clean area, namely all sorts of small pollution sources outside clean area (basically be small this world is mixed microbial) through all sorts of channel, carrier (personnel, stock, barrow) enter clean area, the daily activity because of personnel and the turbulent flow that produce the movement of equipment and generate make these small dirt or microbial in floating in air, be polluted to what clean area creates different level thereby and cause. And this kind of pollution will be right the influence with the manufacturing activity larger generation of the enterprise, the tall look forward to that if produce character amount,do poorly done work over again of not stable, product leads. This appear more apparent in home at present, because,be all the time since a lot of companies of domestic inside the administrative field of clean room is not perfect still, put in the blind angle on a few management, relevant personnel has not paid close attention to or realize this problem; 2 it is to be before this, be aimed at this problem all the time the path of the settlement of neither one effective.
However as in recent years the product upgrades ceaselessly replacement and the innovation that manufacture technology, raised taller requirement to producing an environment, wait for a domain in project of microelectronics, biology especially. The harm problem that clean room small pollution produces an activity to the enterprise also is shown more outstanding, small to clean room pollution undertakes effective pilot asks to also be shown more pressing. Are these small pollution sources of so clean room after all how enter? The research of company of 3M of 500 strong companies of world, United States gave us the answer, this company studies the result shows, all sorts of small pollution sources that enter clean area 80% come from at personnel, 20% come from wait at producing stock and equipment. The main method that solves this one problem at present besides change the clothes, change a shoe, outside crossing wind to drench goods drenchs, another common practice is in those who enter clean area namely the place such as each passageway, passageway uses ground of one-time glue paper to fill up, but because fill up a product one-timely in every respect limitation, use effect is not ideal, even some are restricted like biology and the environment such as life science can be not used.
