Straight floor
Anti-static floors are generally divided into anti-static tiles, PVC anti-static floors and anti-static floors.
1, antistatic tile
In the process of firing ceramic tiles, antistatic powder is added for physical modification, so the antistatic performance is very stable, and the resistance value is between 106 ~ 109 ohm, which is convenient for construction and can be laid by ordinary Plaster workers.
anti static floor
Adding aluminum foil or copper foil under the floor can better enhance the conductivity.
Its advantage is stable antistatic performance. This kind of floor is a national patent product, which is green and environmentally friendly (belonging to green building materials). It has high wear resistance (0. 1g/ 1000 rpm), aging resistance, long service life (more than 30 years), A-class fire resistance and low water absorption (
2.PVC antistatic floor
Paving directly with plates (generally 600×600mm) or coiled materials has a fast installation speed (but it needs professional installers to install it, otherwise it will bulge), and its antistatic performance is relatively stable, but it is easy to age and its anti-pollution ability is slightly poor.
3. Anti-static floor
A, the antistatic effect is excellent and lasting, and it is not affected by time, temperature and humidity;
B, solvent-free high-grade epoxy resin and high-quality curing agent are selected;
C, the surface is smooth, beautiful and moisture-proof, achieving a mirror effect;
D, acid, alkali, salt, oil medium corrosion resistance, especially strong alkali resistance;
E. Wear resistance, pressure resistance, impact resistance and certain elasticity.
free access floor
Anti-static raised floor is generally divided according to the difference of base material and facing material. The base materials are steel base, aluminum base, composite base, particleboard base (wood base), calcium sulfate base, etc. Veneer materials include anti-static tiles, melamine (HPL), PVC, etc. in addition
Ceramic anti-static floor and anti-static plastic floor, OA network floor and so on. The following briefly introduces several types of floors commonly used in the market.
1, ceramic antistatic floor
Anti-static ceramic tile as the surface layer, composite all-steel floor or cement particleboard, surrounded by conductive adhesive strips (ceramic floor without adhesive strips is easy to lose porcelain when bumping). It has the advantages of stable antistatic performance, environmental protection and fire prevention, high wear resistance, long service life (more than 30 years), high bearing capacity (more than 1200kg/ m2), waterproof and moisture-proof, and good decorative effect, and is suitable for all kinds of computer rooms. The disadvantage is that the floor itself is relatively heavy (a floor 15kg or more), which has a certain impact on the bearing capacity of the floor; In addition, professional installation workers are needed to install, otherwise the installation will be uneven.
2. All-steel antistatic floor
(Non-standard and national standard)
The surface layer is made of high wear-resistant melamine HPL fireproof board or PVC (due to gas in the north).
All-steel anti-static floor is dry, which is not easy to be covered with HPL fire-proof board), and the base material of steel shell structure is borderless and borderless according to whether there is black tape.
General engineers choose non-standard type (it is difficult to meet the requirements in terms of electrostatic conductivity and load bearing) because of low price. High score requires national standard type.
All-steel floor is convenient for construction, no cracking after installation and convenient for replacement. The disadvantage is that the surface material is not wear-resistant, has a short service life and is prone to peeling and warping, so it will be replaced in a few years.
3. Aluminum alloy antistatic floor
The products are made of high-quality cast aluminum profiles, stretched and formed, and the surface layer is covered with high wear-resistant PVC or HPL, and bonded with conductive adhesive, which has the effect that the substrate will never rust for many times, effectively solving the product defects of composite floors and all-steel floors, and the price of tailor-made high-grade anti-static floors is too expensive.
