Spreading cover on a stone material surface, not only is to cover the stone material hair side, hollow, crack and scratch, enhances the stone material glossiness, but also to protect the stone material from the water or other bad factors, like SO2 and so on noxious gas has corrosive nature to the stone material, thus to avoids or postpone stone material surface oxidation, so to have the protection function.

在石材表面涂覆一层遮盖品，不单纯是为了掩盖石材毛面，凹陷、裂纹和划痕，提高石材的光泽度，还可保护石材免受水或其他不良因素，如SO2等有害气体对石材的侵蚀作用，避免或延缓石材表面氧化作用的发生和发展，从而起到保护的作用。

With low donor and acceptor density and anion adsorption on surface of passive film, effectively preventing the adsorption of Cl(superscript -) in passive film, the resistance to localize corrosion of passive film was greatly improved.

低的施主与受主浓度及钝化膜表面负电荷的增强，可有效排斥侵蚀性Cl在钝化膜表面的特性吸附，有利于提高不锈钢的耐局部腐蚀性能。
