Light plastering gypsum is a kind of gypsum powder. Light plastering gypsum is a kind of single component plastering and leveling material prepared by taking industrial by-product gypsum as cementitious material, vitrified micro beads or expanded perlite as light aggregate and adding a variety of admixtures. It has the characteristics of early strength and fast hardening, good adhesion, light weight and micro expansion. Light plastering gypsum can be used to replace traditional cement mortar to solve problems such as hollowing and cracking of wall surface, The emergence of light plastering gypsum improves the construction efficiency in the construction industry and decoration industry.

浅谈原材料对轻质石膏质量影响。

The influence of raw materials on the quality of light gypsum.

原材料对轻质抹灰石膏粉产品的质量有着至关重要的影响。石膏是胶结材料，它的作用是将玻化微珠等颗粒材料黏在一起，凝固后产生一定的强度。该项目所用的脱副产石膏是工厂的固体废弃物，所以，在对其品质必须进行进厂进行检验，以保证和实验室所作配方的要求保持一致。玻化微珠是轻质抹灰石膏的核心原料，其密度、强度、颗粒直径对产品终性能起到了关键性的作用。

Raw materials have a vital impact on the quality of light plastering gypsum powder products. Gypsum is a cementitious material. Its function is to stick granular materials such as vitrified beads together and produce a certain strength after solidification. The de by-product gypsum used in the project is the solid waste of the factory. Therefore, its quality must be inspected in the factory to ensure that it is consistent with the requirements of the formula made in the laboratory. Vitrified beads are the core raw materials of light plastering gypsum. Their density, strength and particle diameter play a key role in the final performance of the product.

化学添加剂如高分子聚合物等可以地提高终产品的性能和应用范围。添加剂是以微量来进行计量和掺入的，是以千分之一甚至是十万分之一的比例进行混合。通常，成品性能越高，其配方的原材料愈复杂，分散性要求越高。所以计量的的搅拌的均匀和率对于所有的产品都是非常关键的。

Chemical additives such as high molecular polymers can greatly improve the performance and application range of end products. Additives are measured and added in trace amounts, and are mixed in the proportion of 1 / 1000 or even 1 / 100000. Generally, the higher the performance of the finished product, the more complex the raw materials of its formula and the higher the dispersion requirements. Therefore, the uniformity and rate of mixing are very important for all products.
