新:硅藻泥專用鈦白粉R218金紅石型 油畫布專用鈦白粉 廣告布專用鈦白粉
產品描述 (Product description)
R218是由硫酸法最新生產工藝制造的金紅石型二氧化鈦。獨特的水解、煅燒工藝，使本產品具有無與倫比的遮蓋力。先進、精細的研磨，使它粒度分布更均勻，光澤度更高；經過特殊的表面處理，R218擁有了更好的耐候性，更低的吸油量，更好的流平性。生產裝置的大型化，先進的DCS控制系統，以及我公司強大的技術力量和豐富的管理經驗，使得本產品具有了更穩定出色的品質。
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.
