为促进技术进步,提高石灰产品质量,以适应我国建筑业发展的需要,国家建材局委托中国建材工业协会制订建筑生石灰粉标准,并对现行的建筑生石灰,建筑消石灰粉和建筑石灰检验方法等三个标准进行修订。这次制、修订的四个标准均标志着我国石灰工业的技术水平。为此,在标准项目设置上,编制人员从实际出发并结合我国国情,本着不片面追求高化学指标,而以各种石灰产品的物理指标为主的原则,初步考虑增设产浆量、安定性、消解速度等物理指标,对石灰含
In order to promote technological advancement and improve the quality of lime products to meet the needs of the development of China’s construction industry, the State Administration of Building Materials commissioned the China Building Materials Industry Association to formulate the standards for building lime powder, and the existing methods for building quicklime, building hydrated lime and building lime, etc. Revised standards. The four standards adopted this time and revised all mark the technical level of China’s lime industry. For this reason, in the standard project setting, the preparation personnel proceed from the actual situation and combined with the national conditions in China, and pursue the principle of high chemical index, while taking the principle of physical indicators of various lime products as the principle, preliminary consideration should be given to increasing the output and stability of the slurry. Physical indicators such as sex, digestion speed, etc.
