Cleanroom mats should be placed in an area where it will be on clean hard flooring. It should be placed just before the ingress point for EACH clean area or with greater degree of cleaning.
Cleanroom mats should be placed so that all those passing through that point must step on the mats.
The mats should be placed with the longer dimension of the mat in the same direction as the traffic flow for maximum footfalls on each mat.
The minimum number of footfalls should be two with each foot for each location.
The proper size of cleanroom mat for each area of placement is dependent on the width of the opening and the direction and variance of the traffic. Normally the width of the mat should be 2/3rds to 3/4ths of the width of the doorway. It does not normally need to cover the full width because normal traffic, when approaching from the perpendicular direction, passes through the middle of the doorway and not along the edge.
However, if the traffic may come from an the side of the entry way or at a sharp angle then the width of the mat needs to be wider than the doorway to allow for enough footfalls.
The length of the mat should be long enough to provide two footfalls with each foot at each location, for example 45” – 114 cm.
The color of the cleanroom mats can vary from standard blue, white and gray to personalized colors with printed messages. Color has no effect on the function of the mat. On all available colors the deposited contamination is clearly visible, facilitating the setting of a program to replace the contaminated layer at regular intervals or on need.
How often the layers should be removed depends on numerous variables.
Based on the parameters listed above, the moment of layer change can be determined after a few days of use and observation.
Before placing a new cleanroom mat down or replacing an existing mat make sure to clean thesurface to remove contamination that may act as a barrier and keep the mat from adhering. If you are replacing an existing mat make sure to clean any adhesive residue through the use of an alcohol-based detergent.
Make sure the surface is completely dry before application. To apply the mat, remove half of the release liner in the long direction of the mat. This will help with the alignment of the mat. Once you have the mat in the location you want and it is properly aligned start smoothing out the half of the mat with the adhesive exposed. Start at on end and work toward the middle making sure you do not trap air under the mat as you go, then remove the rest of the release liner and smooth the rest of the mat out in the same direction you removed the release liner.
Cleanroom mats should be stored for several hours in similar climate conditions as the point of use. The mats should be used in a controlled environment setting for ideal results but may be placed in any area that has a temperature of 12-35 C°.
Long term storage of product should always be on a hard, flat and solid surface. Storage on the original shipping pallet is recommended. Storing the mats on edge is not recommended as this will allow the mats to wrinkle and may render them unusable.
Normal warehouse conditions are generally acceptable, but temperatures extreme for prolonged periods (less than 0 or above 40 °C) must be avoided. In normal storage conditions, the product will not undergo changes in performance for a three year period.
