On the Attrition Resistance of the Impact Crusher Plate of Fan-type Pulverizer 风扇磨煤机冲击板磨损的特性分析
The promotor is featured by convenience in adding into FCC plants, higher stability and attrition resistance, and better octane number and induction period of the gasoline produced. 该助剂添加方便,稳定性及耐磨蚀性良好,所产汽油的辛烷值及诱导期均有明显改善。
Alumina ceramics, as one of the important advanced ceramic materials, has been widely used in many fields owing to its many excellent properties such as high-strength, high-temperature-resistant, good attrition and high resistance, and so on. 氧化铝陶瓷具有高强度、耐高温、耐磨性好和电阻率大等优良的综合性能,广泛应用于电子、机械以及化学工业与领域。
Blending porcelain powder into the gold-paste is a feasible way to improve the attrition resistance of the layer and the surface roughness after polishing has no difference. 在金泥中加入一定比例釉瓷粉是提高金泥涂层耐磨性的可行性方法,釉瓷粉加入后对金泥涂层抛光后表面粗糙度无影响,不影响临床应用;
A Study on the Improving the Attrition Resistance of the Gold-paste Layer Fused to Ni-Gr Alloy Through Blending Ultra-fine ZrO_2 超细氧化锆对提高金泥涂层耐磨性的实验研究
The results of industrial operation shows MB-86 has good stability, high attrition resistance and rational product distribution. 工业运转结果表明,MB-86催化剂稳定性及耐磨性良好,反应产物分布合理。
The attrition of the catalyst was mainly due to the chemical attrition. The morphology observation of the catalyst after FTS run for 600 h showed that the attrition resistance was enhanced by increasing the calcination temperature, and the catalyst calcined above 400 ℃ exhibited robust attrition resistance. 反应600h后卸载下的催化剂的形貌观测表明,催化剂的磨损主要是由化学磨损引起的,提高焙烧温度可明显改善其抗磨损性能,焙烧温度高于400℃时,催化剂具有较好的抗磨损性能。
With the development of economy the stainless steel has been wildly used in many fields with its favorable corrosion resistance and attrition resistance and mechanical working properties. 不锈钢具有优良的耐腐蚀性、韧性、一定的耐磨性和加工性能,随着国民经济的发展,得到了越来越广泛的应用。
