R-258钛白粉
R-258钛白粉属于新一代高档通用型（偏水性）金红石钛白粉，适用于各种建筑涂料、工业漆、防腐漆、油墨、粉末涂料等行业。R-258钛白粉具有以下特性：
高耐候性：R-258钛白粉具有较高的金红石含量，晶格完整，填充剂加量足，采取了足量的锆硅铝磷多元无机包膜和有机处理，因此能保证较高的耐候性。
优秀分散性：特殊的无机表面处理和有机表面处理减少了TiO2粒子之间的接触，使R-258钛白粉在应用过程中表现出优秀的分散性。因而R-258钛白粉润湿性好，易研磨。
低吸油量：R-258钛白粉的低吸油量，使钛白粉在涂料、油墨的应用过程中保持良好的流动性，利于节约成本。
低磨耗：采用特殊的水解、盐处理、煅烧和表面处理工艺，使钛白粉粒子较软，易研磨，因而R-258钛白粉磨耗低。

R-258 titanium dioxide belongs to a new generation of high-end general-purpose (partial water-based) rutile titanium dioxide. R-258 titanium dioxide applied to a variety of architectural coatings, industrial paints, anti-corrosive paint, ink, powder coating and other industries. R-258 titanium dioxide having the following characteristics:
High weather resistance: R-258 titanium dioxide having a high rutile content, the lattice integrity, sufficient amount of filler added, to take a sufficient amount of phosphorus zirconium aluminosilicates polybasic inorganic envelope and the organic treatment, thus ensuring a higher weatherability sex.
Excellent dispersion: special inorganic surface treatment and the organic surface treatment reduces the contact between the TiO2 particles, so that R-258 titanium dioxide exhibits excellent dispersibility in the application process. Thus R-258 titanium dioxide, good wettability, and easy to grind.
Low oil absorption: low oil absorption of the R-258 titanium dioxide, titanium dioxide to maintain good liquidity in the application of coatings, inks, which will help to save costs.
Low wear: hydrolysis, salt processing, calcined and surface treatment process, the titanium dioxide particles is relatively soft, easy to grind, and thus wear low R-258 titanium dioxide.
