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.

淺談原材料對輕質石膏質量影響。

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

原材料對輕質抹灰石膏粉產品的質量有著至關重要的影響。石膏是膠結材料，它的作用是將玻化微珠等顆粒材料黏在一起，凝固后產生一定的強度。該項目所用的脫副產石膏是工廠的固體廢棄物，所以，在對其品質必須進行進廠進行檢驗，以保證和實驗室所作配方的要求保持一致。玻化微珠是輕質抹灰石膏的核心原料，其密度、強度、顆粒直徑對產品終性能起到了關鍵性的作用。

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.

化學添加劑如高分子聚合物等可以地提高終產品的性能和應用范圍。添加劑是以微量來進行計量和摻入的，是以千分之一甚至是十萬分之一的比例進行混合。通常，成品性能越高，其配方的原材料愈復雜，分散性要求越高。所以計量的的攪拌的均勻和率對于所有的產品都是非常關鍵的。

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.
