从1985年起,哈萨克矿井建设托拉斯的一些工地在全苏矿井建设组织和机械化科学研究院的帮助下,使用了高效防腐蚀材料。材料及喷涂工艺制度的选择决定于介质的侵蚀性和表面喷涂条件。按化学分析结果,井下金属结构要遭到强烈矿化的矿井水的腐蚀,这种矿井水 pH=5.8～9.9,含氯化物(0.8～3.9g/L)和硫酸盐(0.13～1.5g/L)。井口地面金属结构既遭到特殊矿井的大气(工业大气受到氮和硫的氧化物及煤尘和岩尘的污染)的侵蚀,又受到北哈萨克斯坦气候条件的影响,年腐蚀速度为0.1～0.7mm,这相当于弱的和中等的空气介质侵蚀。哈萨克矿井建设托拉斯根据研究结果,并考虑介质的侵蚀性,建议在经机械清理的金属
Since 1985, a number of sites in Torres, Kazakhstan’s mine construction site, have been using efficient anti-corrosion materials with the help of the All-China Mine Construction Organization and the Institute of Mechanized Science. The choice of material and spray process system is determined by the aggressiveness of the medium and the surface coating conditions. According to the results of chemical analysis, the underground metal structure is subject to the erosion of strongly mineralized mine water with pH = 5.8 to 9.9, chloride (0.8 to 3.9 g / L) and sulfate (0.13 to 1.5 g / L). The wellhead ground metal structure is eroded not only by the special mine atmosphere (industrial atmosphere is contaminated by nitrogen and sulfur oxides, coal dust and rock dust), but also by the weather conditions of northern Kazakhstan. The annual corrosion rate is 0.1-0.7 mm, which is equivalent to weak and medium air erosion. According to the results of the study, and taking into account the aggressiveness of the medium, it is proposed that the mechanical cleaning of metal
