Selecting the right wipe

摘要

Cleanrooms and other controlled environments require stringent control of particles, residues and micro-organisms to ensure desired product or process outcomes. Each industry has its own critical parameters: ions and particles in electronics; microbes, endotoxins and particles in life-sciences; fibres and silicone in automotive painting and graphics printing. The control of these critical parameters is very often achieved by the use of wipes, either dry or pre-saturated. There is a huge range of wipes available to cleanroom users, manufactured from a wide variety of substrates, made with different manufacturing methods, finished with different surface treatments to enhance particle pick-up or increase sorbency, differing weights and size, level of cleanliness, and choice of impregnate.
