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(duì)輕質(zhì)石膏質(zhì)量影響。

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

原材料對(duì)輕質(zhì)抹灰石膏粉產(chǎn)品的質(zhì)量有著至關(guān)重要的影響。石膏是膠結(jié)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(chǎn)生一定的強(qiáng)度。該項(xiàng)目所用的脫副產(chǎn)石膏是工廠的固體廢棄物，所以，在對(duì)其品質(zhì)必須進(jìn)行進(jìn)廠進(jìn)行檢驗(yàn)，以保證和實(shí)驗(yàn)室所作配方的要求保持一致。玻化微珠是輕質(zhì)抹灰石膏的核心原料，其密度、強(qiáng)度、顆粒直徑對(duì)產(chǎn)品終性能起到了關(guān)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(xué)添加劑如高分子聚合物等可以地提高終產(chǎn)品的性能和應(yīng)用范圍。添加劑是以微量來(lái)進(jìn)行計(jì)量和摻入的，是以千分之一甚至是十萬(wàn)分之一的比例進(jìn)行混合。通常，成品性能越高，其配方的原材料愈復(fù)雜，分散性要求越高。所以計(jì)量的的攪拌的均勻和率對(duì)于所有的產(chǎn)品都是非常關(guān)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.
