Static floor overview
Anti-static floor is also called dissipative static floor. It is a floor that, when grounded or connected to any lower potential point, dissipates the charge, characterized by a resistance between 1.0 and 10 to the power of 5 to 10 and 9 to the Ω.
classification
(1) Electrostatic floor can be divided according to different forms of electrostatic discharge: conductive static floor (volume resistance less than 10 to the fifth power) and anti-static floor (also known as antistatic floor, volume resistance at 10 to 5 to 10 ten Between the two parties, their use is also different, for example, the power station must use anti-static floor and can not use static conductive floor.
(2) Static floor can be divided into: straight floor and raised floor (also called overhead floor) according to the form and function of the paving.
a, the straight floor can be divided into anti-static tiles, anti-static PVC floor and so on. Anti-static tile is made by mixing conductive powder into cement mortar and adding conductive tape. The construction process is simple, and the ground is easy to clean when used (it can be dragged with mop without dripping), high wear resistance and long service life. In contrast, PVC flooring is not resistant to aging, is not easy to clean, and has poor fire resistance.
b. The raised floor can be divided into steel base, aluminum base, composite base, particle board base (also called wood base), calcium sulfate base, etc. according to different materials of substrate and veneer. The veneer can be anti-static ceramic tile or melamine ( HPL) and PVC.
The price of aluminum-based and calcium-sulfate-based is high, and the aluminum-based floor will not rust, but the accuracy of the domestic aluminum-based floor is not high, the price of imported aluminum base is too high; the steel base and composite base are moderate, but the steel-based floor section It is easy to rust, so the section needs to be painted to prevent rust. The cross section of the composite base is also dust-proof; the price of the particleboard base is lower, but the water absorption rate is too high, and the fireproof performance is poor, the load is low, and it is not suitable. Steel-based and composite-based flooring are increasingly popular on the market.
Using melamine (HPL) for veneer is easy to age and peel, the surface is easy to scratch, the corners are easy to fall off; the veneer is easy to aging with PVC, it is not easy to clean after paving, the floor is easy to age, and the fire performance is not good; Two kinds of anti-static ceramic tiles are the best, not only fireproof performance, but also easy to clean, high wear resistance, anti-aging.
