According to the activity of fine filler used in dry mix mortar, it can be divided into two kinds- active filler and inert filler. The active filler is made from natural mineral material or industrial waste residue, which can be directly used or pre-milled. It is a kind of fine powder material directly mixed into … Continue reading
Different dry powder mortar products require different performance requirements and require dispersible polymer powder to provide suitable performance. The following focuses on the role of dispersible polymer powder in tile adhesives and mortars for exterior wall insulation polystyrene board, and briefly describes the role of redispersible powders in various major dry mortar products. Application of … Continue reading
Skim coating is a texturing technique used to make a wall smooth. Drywallers use this technique to hide an imperfect taping job, to give the wall a plaster-like appearance and in situations when only the smoothest surface will do. Skim coating is the only way to achieve a level 5 drywall finish, which a number … Continue reading
In the construction industry, the transformation of construction technology is based on the innovation of building materials. In recent years, polymer-modified dry mortar has shown a booming development in China. One of the outstanding examples is the emergence of polymer-modified dry powder tile adhesives, which is transforming the tile inlay process from the traditional thick … Continue reading
Starch ether is one of the most prolific natural polymers, and is composed of amylose and amylopectin. Amylopectin molecules are much larger than amylase. Starch ethers are chemically modified from starch. Potato starch, which is of high-purity, is the preferred amylase for building. Starch molecular weight and the degree of etherification determine the consistency and … Continue reading
HPS (short for hydroxypropyl starch ether) enables cement- and gypsum-based products with distinctive qualities. Similar to Hydroxypropyl Methylcellulose(HPMC) in the chemical structure, it can not only provide functions similar to cellulose, but also have very good compatibility with other additives in building. starch ether has a very small amount used in mortar products, and a … Continue reading
