中国现有钛白粉生产企业约50多家,生产能力20万t/a,1998年产量为14万t。由于产品结构不合理,普通锐钛型钛白粉所占比重过大,而化纤级钛白粉和高档金红石型钛白粉几乎全部依赖进口。国际上氯化法钛白粉处于高度垄断的地位,装置投资巨大,国内发展困难重重。因此,国内企业可抓住国际上硫酸法锐钛型钛白粉生产的不足,发挥自身优势,增加产品出口。
There are about 50 titanium dioxide production enterprises in China, with a production capacity of 200,000 t/a and 140,000 t in 1998. Due to the irrational product structure, the proportion of ordinary anatase titanium dioxide is too large, while chemical fiber grade titanium dioxide and high-grade rutile titanium dioxide are almost all dependent on imports. The international chlorination process titanium dioxide is in a highly monopolistic position, with huge investment in equipment and difficulties in domestic development. Therefore, domestic companies can seize the international shortage of sulfuric acid process titanium azide titanium dioxide production, play its own advantages, increase product exports.
