產(chǎn)品描述 (Product description) 
R218是由硫酸法最新生產(chǎn)工藝制造的金紅石型二氧化鈦。獨(dú)特的水解、煅燒工藝，使本產(chǎn)品具有無與倫比的遮蓋力。先進(jìn)、精細(xì)的研磨，使它粒度分布更均勻，光澤度更高；經(jīng)過特殊的表面處理，R218擁有了更好的耐候性，更低的吸油量，更好的流平性。生產(chǎn)裝置的大型化，先進(jìn)的DCS控制系統(tǒng)，以及我公司強(qiáng)大的技術(shù)力量和豐富的管理經(jīng)驗(yàn)，使得本產(chǎn)品具有了更穩(wěn)定出色的品質(zhì)。 
R218 is rutile titanium dioxide made by sulfate process. It has an unparalleled hiding power due to the unique hydrolysis and calcination process. Advanced、fine grinding process make the particle size distribution more uniform and higher gloss；As a result of a special surface treatment, R218 has a better weather resistance, lower oil absorption, better leveling property. 
Large-scale production equipment, advanced DCS control system, as well as our company's strong technical force and rich management experience, makes the R218 with a more stable and excellent quality.
