OF super grade, Grade I and II is exported. Fine talcum powder is of high whiteness in very fine granula tion which feels soft and slippery, so it is used in hitech fields, such as paint and coating industry, it is also used in paper making industry. Besides calcine talcum powder from 200 mesh to 1250 mesh is used in china and pottery industry. The following kinds such as Qixia3-grade blocks, 3-grade grains, 4 grade block and 4-grade grains are used as raw materials of china and pottery products. When 15% 80% of talcum powder is added in porcelain ,the Final china products is of very heat expansion, but of high strength, transparency and brilliance in colure and of very high percentage silicon , alg but of very low percentage of iron and aluminium.

The diamond thin films can not only be deposited on large areas, but also be deposited at complex curve surfaces.

金刚石薄膜不仅面积较大，而且可以淀积出复杂的曲面形状，也可以作为涂层覆盖在特定的工件表面上。

The changes of curvature in concavo-convex surface resulted in great non-uniform paint deposition when speed was constant.

针对表面有凹凸结构的复杂曲面，采用匀速喷涂方法，曲面上曲率的变化造成涂层厚度差较大。

The effect of die design on coating concentricity of optical fiber at high drawing speed is investigated.

研究了在高速拉丝条件下涂覆模具的设计对光纤涂层同心度的影响。

In high speed drawing process,the pressure gradient of coating in die determines the magnitude of centering force and the concentricity of coating layers.

高速拉丝过程中，模具中涂料的压力梯度决定了对中作用力和光纤涂层同心度的大小。

But for the strong activity of Nano-TiO2, the conglobation will happen easily, and it will greatly reduce the application effect in coating. And for the hydrophilicity , its hard to break up uniform in resins, so air gaps appear in the interface, then the high polymer in the interface willhappen degradation reaction or embrittlement reaction, and coatingsperformance will fall down.

但是由于纳米粒子表面极强的活性，使它们很容易团聚在一起从而形成带有若干弱连接界面的尺寸较大的团聚体，这大大降低甚至消除了纳米颗粒的实际应用效果，同时由于纳米粒子表面亲水疏油，在有机高分子树脂中难于均匀分散，界面上会出现空隙，当空气中的水分进入空隙中就会触发界面处高聚物的降解、脆化，导致涂层失效。

It is used in the every working steps of steel products and the connation of the inventory.
