Gypsum plaster is widely used in dry-mixed mortar products. Whether it is hand-applied plaster or machine-applied plaster, starch ether plays a very important role in it. The influence of starch ether on the thickening of freshly mixed mortar can provide thickening effect for plaster, so that plaster can quickly reach a suitable consistency during construction… read more →

After the mortar is mixed with water, the layered swelling silicate in the thixotropic lubricant can form a gel due to the presence of an aqueous medium, which improves the basic viscosity of the system. Due to the formation of the card house structure, the flow of the mortar is improved, which is represented by the.. read more →

Thixotropic lubricant is mainly used in dry mixed mortar products to improve the construction performance of wet mortar, achieve uniform surface, increase sag resistance and the thickness of mortar… Plastering and stucco are the special building materials used for interior and exterior walls and ceilings, and the adhesives used can be cement based, gypsum based with polymer.. read more →

The rheological additives used in cement-based tile adhesives and other systems are mainly cellulose ethers, which provide suitable consistence for construction, sag resistance of wall tiles, optimum water retention of cement, and control intervals and tile correction time. The thixotropic lubricant can be used in combination with cellulose ether thickeners to create a synergistic effect that improves the sag.. read more →

1). Application in tile adhesive Based on test formula as follows- A. Portland cement (p·O, 42.5R): 37% B. Sand gradation: 61.2% C. Hydroxy propyl methyl cellulase: 0.3% D. Redispersible polymer powder: 1.5% E. cellulose fiber: 0.3% Adding cellulose fiber into different formulas of tile adhesive can significantly reduce the slide distance. That is to say cellulose fiber in ceramic tile adhesive does not reduce the workability,.. read more →

The consistency and anti-sagging performance of mortar are very important indicators. The mortar must be easy to apply, at the same time with the appropriate consistency and no sagging while applying as thick mortar. Same properties are required in tile adhesive, which can help to support heavy bricks perpendicular to the wall. The testing method of consistency- International standard EN 1015-3 fresh mortar test methods.. read more →

External wall insulation and EIFS are used in the global field. The installation on the exterior wall of the building mainly save 40%-70% of the energy consumption of building heating and cooling. The polymer powder modified dry mortar is used to bond polystyrene sheets to the wall(bonding mortar). At the same time, in order to protect.. read more →

Starch ethers are used in cement-based systems such as plastering, adhesives, and leveling layer to form functional surfaces both internally and externally. Plastering mortar is used to cover uneven parts of walls. They must have a strong and durable bond to the substrate. The surface of the mortar must become smooth and flat in order to give uniform absorption and good.. read more →

A. The rheology properties of starch ether in machine and spray mortar Starch ethers prevent sagging of mortar and enhance pumping properties. They are easy to distribute evenly in mortar because they are of low viscosity, can dissolve fast, change the rheology of the plaster and gave it thixotropy. This shows that when the external force.. read more →

Hydroxypropyl Methyl Cellulose Ether (HPMC) are referred to as Methyl Cellulose ether (MC). MC is one of the most important additives in dry powder mortar which mainly plays the role of water retention and thickening.   MC is a kind of powdered cellulose ether made of wood fiber or refined short cotton fiber as the main.. read more →
