Basic knowledge of sticky mat
1. The role of sticky mats
Sticky floor mat is one of the daily consumables in clean room and has the following functions.
(1) Sticky mat can effectively prevent pollutants and particles from entering the working environment with strict requirements due to the flow of personnel, and keep the working environment clean.
(2) mainly sticks to the entrance of clean room or buffer zone, it can effectively capture and remove the dust pollution on the sole, heel (or wheel).
(3) Minimize the impact of dust on the quality of the purification environment, so as to achieve the effect of simple dust removal, and solve the problem of incomplete dust removal of other floor mats and the inability to ensure that the dust does not spread.
2. What is the material composition of the sticky mat?
The material composition of the sticky floor mat is low-density polyethylene material and water-soluble acrylic. Generally speaking, it is composed of PE film and viscose.
3. What is the structural composition of the sticky mat?
Sticky layer mat is usually composed of 1 layer of glueless PE protective mask, 29 layers of single-sided glued PE film, 1 layer of double-sided glued PE film, and 1 layer of glueless PE surface protection base film.
4. What are the application areas of sticky mats?
(1) From the perspective of industry, sticky dust mats can be applied to various industries that have high requirements on the environment, such as microelectronics, semiconductors, biopharmaceuticals, life sciences, precision machinery manufacturing, automobiles, food, hospitals, laboratories Wait.
(2) In terms of application area, sticky dust mats are mainly used for entrances and exits into clean areas, such as personnel passages, production material passages, dressing rooms, air shower rooms, cargo shower rooms, paint spray booths for automobiles, and operating rooms in hospitals Entrance, entrance and exit of infectious disease areas, etc.
(3) We recommend the use of sticky mats in the entrances, passages, dressing rooms and other areas of clean areas of class 10,000 and above. Clean areas below class 10,000 should also be used when there are many people, goods and vehicles in and out.
5. What are the factors to consider for sticky floor mats?
To evaluate the quality of sticky mats, mainly refer to the following aspects:
(1) Thickness of low density polyethylene material
(2) Tensile strength of low density polyethylene material
(3) Uniformity of adhesive coating
(4) Viscosity of surface adhesive coating
(5) Viscosity of the adhesive coating on the back
6. Is the stickiness of the sticky mat the better?
actually not. The viscosity of the sticky mat selected depends mainly on the applicable environment and the structure of the sole. Generally speaking, the sticky mat with higher viscosity should be selected at the entrance between the external environment and the clean room, and the low viscosity sticky mat can be used for the buffer zone between the adjacent clean rooms. The higher the viscosity of the sticky mat, the greater the possibility of sticking residual glue on the sole.
7. Any suggestion to buy sticky dust mat?
(1) Choose the color according to the surrounding environment such as the dressing room, air shower room, aisle, etc., usually blue.
(2) According to the size of the channel, determine the size of the sticky mat. Standard sizes: 18”×45”, 24”×36”, 26”×45”.
(3) Select the matching viscosity according to the material and texture of the work shoes.
(4) Choose the number of layers according to the replacement frequency, usually 30 layers.
8. What are the requirements for the use of sticky mats?
(1) Before laying, make sure that the ground is clean, dry and level.
(2) When laying, the protective bottom film should be removed to make the back side stick to the ground, and the pressure should be flattened to eliminate air and ensure full contact.
(3) Remove the PE film with dust in time
