Abstract
A variety of static electricity troubles are reported in the production facilities,and the anti-static performance is indispensable to the floor material.However,usual coating floor material with anti-static performance is deteriorated at caster running on it.Then,authors developed coating floor material with anti-static,which has enough durability for various deteriorations,and an enough anti-static performance was possessed after the accelerated degrading test.However,there are uncertain points like a change of the anti-static performance for this developed coating floor material.This paper describes that;a change of the anti-static performance and the influence of initial care condition and the construction condition on anti-static performance.
