石灰石是基本化工产品如纯碱、电石等的主要原料。它是一种产量大、产地多、用途广的天然产品。长期以来,由于没有化工用石灰石国家或行业标准,加上地方标准、企业标准也很少,致使石灰石矿山和用户之间对该产品的检测方法和产品质量存在着分歧,迫切希望能制订一个统一的化工用石灰石标准。为此,化工部下达了“化工用石灰石”行业标准和“化工用石灰石分析方法”国家标准的制订任务,于1993年完成标准草案(报批稿),负责起草单位为化工部化工矿山设计研究院。经过两年多的工作,起草工
Limestone is the main raw material for basic chemical products such as soda ash and calcium carbide. It is a natural product with large output, many producing areas and wide applications. For a long time, because there are no national or industrial standards for limestone used in chemical industry, and there are few local standards and corporate standards, there is a disagreement between the detection methods and product quality of limestone mines and users, and it is eager to formulate a unified one. The limestone standard for chemical use. To this end, the Ministry of Chemical Industry issued the “Limes for Chemical Industry” standard and the “National Limestone Analysis Method for Chemical Industry” national standard. It completed the draft standard (approved draft) in 1993 and was responsible for the drafting of the chemical mine design and research institute of the Ministry of Chemical Industry. . After more than two years of work, the drafter
