??????? ??? [Description]? 1 from the environment, the species has a long-term, stable anti-static properties, volume resistivity and resistance tables were between 1x105-1x109. (It won, t be influenced, and has permanent and stable anti-static Functions with body resistance and surface resistance between 1x105-1x109Ω) 2 weather resistance, -60. C-600. C environment, its physical and chemical properties and anti electrical properties of the same. It has excellent heat-resisitant performance and the conductivity won, t change between -60. C-600. C 3 corrosion, acid, oil-resistant, fireproof grade A, impermeable. It is incomparably wear-resisting, acid-proofing, smeary resisting, flame retardancy and prevent penetration 4 ceramic texture, never aging, hard wear-resistant, and architecture with life. It is made of ceramic, and never aging 5 non-toxic, tasteless, no radiation, is a green product. It is green environmental products, and it is non-toxic, tasteless And non-radiation 6 varieties can be arbitrarily selected. You can choose any design, color or type at ease 7 rounds of small dust, and the caulking used in conjunction with a high level of cleanliness to meet environmental requirements. The dust capacity is low and it can meet higher requirements of clean environment when used with caulking agent 8 construction is simple, fast and suitable for use in a variety of new and old buildings. It canbe used in both new and old buidings as the construction is quite easy
