Impact of HPMC on gypsum products
With the rapid development of the construction industry, there is a growing demand for new building materials. Due to the increasing awareness of environmental protection and the increasing efficiency of construction, gelling materials and plaster products have been developed rapidly. The most common plaster products nowadays are gypsum plaster, adhesive plaster, embedded gypsum and tile adhesives.
Gypsum plaster is a high quality plastering material for internal walls and ceilings. After use, the wiped wall surface is smooth and delicate, not powdered, firmly bonded with the substrate, no cracking or peeling phenomenon. And it has a fireproof function.
Adhesive plaster is a new adhesive for construction light boards, which is a sticky material made of gypsum as the base material with a variety of additives. It is suitable for bonding between all kinds of inorganic building wall materials. It is non-toxic, odourless, early, strong, fast curing and firmly bonded and can be used as a support material for building panels and buildings.
These gypsum products have a range of different functions. Gypsum and associated fillers play a role. In addition, the key issue is that the addition of cellulose ether additives plays a leading role. As gypsum can be divided into hard gypsum and hemihydrate gypsum, different types of gypsum have different effects on the performance of the product, so properties such as thickening, water retention and slow setting determine the quality of gypsum building materials.
