本标准适用于以风化煤为原料制取的用于蒸汽机车锅炉水处理的固体腐植酸钠水质稳定剂。 1 总则 1.1腐植酸钠防垢剂的生产,其质量必须符合本标准的各项规定。 1.2对原水水质要求符合一般天然水质。在使用腐植酸钠前、后,应根据本地区水质情况选择分析项目。主要分析总硬度、总碱度、钙、镁、钠和钾、硫酸根、氯根、二氧化硅、溶解性蒸发残渣、pH值。 1.3在正式使用腐植酸钠之前,需做常压防垢率试验。 2 技术条件 2.1风化煤原料中的腐植酸含量应在40％以上。 2.2腐植酸钠为无毒、无味黑色粒状固体,粒度在20目以下。 2.3腐植酸钠是有机高分子复合物,易
This standard applies to weathered coal as raw material for steam locomotive boiler water treatment of solid sodium humic acid water stabilizer. 1 General 1.1 Sodium humate antiscale production, the quality must comply with the provisions of this standard. 1.2 on the raw water quality requirements in line with the general natural water quality. In the use of sodium humic acid before and after, should be based on the situation in the region to choose the analysis of water quality projects. The main analysis of total hardness, total alkalinity, calcium, magnesium, sodium and potassium, sulfate, chloride, silica, dissolved evaporation residue, pH value. 1.3 In the official use of sodium humate, the need to do atmospheric pressure scaling test. 2 Technical conditions 2.1 Weathered coal raw material humic acid content should be 40% or more. 2.2 Sodium humate is non-toxic, odorless black granular solid, particle size below 20 mesh. 2.3 Sodium humate is an organic polymer complex, easy
