Meanwhile, the preparations of different crystal form calcium carbonate are also studied in this paper.

Selecting tests showed, Although both Cyclohexylamine carbonate salt and Ammonium carbonate had excellent static or dynamic protecting effects for A3 steel, and there is not any rust appearance to be found in the surface of coupon sample, yet the volatilizing and weight loss is heavy;

筛选试验结果表明，碳酸环己胺、碳酸铵对A3钢具有很好的静态和动态保护效果，试验期间试片光亮无锈，但缓蚀剂挥发失重较大；
