前言钛白粉是一种重要的化工产品,在涂料、化纤、造纸、焊条、电容器、塑料、冶金等工业部门都有广泛应用。我国极其丰富的钛资源,为钛白粉工业的发展提供了有利条件。但是,由于生产技术和设备的落后现状,限制了它的发展,产量供不应求,所以每年必须靠大量进口补差。 Preface Titanium dioxide is an important chemical product widely used in coating, chemical fiber, papermaking, welding rod, capacitor, plastic, metallurgy and other industrial sectors. Our country is extremely rich in titanium resources for the development of titanium dioxide industry has provided favorable conditions. However, due to the backward production technology and equipment, its development has been limited and its output is in short supply. Therefore, a large amount of imports must make up for the deficit each year.
