Basic Concept of Redispersible Powder The Redispersible Powder is the main additive of dry powder ready-mixed mortar such as cement-based or gypsum-based. The Redispersible Powder is a polymer of vinyl acetate and ethyl ester which is spray-dried and gathered from the original 2μm to form spherical particles of 80-100μm. Since the surface of these … Continue reading
Application of Cellulose Ether in Dry Mortar In the dry mortar, cellulose ether plays the role of retaining water, thickening and improving construction performance. Good water retention performance ensures that the mortar will not be sanded, dusting and strength due to lack of water, cement hydration incompleted, thickening effect makes the structural strength of … Continue reading
Fineness of Cellulose Ether Fineness is also an important performance indicator for cellulose ether. The Hydroxypropyl Methylcellulose requirement for dry mortar is powder, low water content, and the fineness also requires 20%-60% of particle size to be less than 63um. Fineness affects the solubility of cellulose ether. The coarser Hydroxypropyl Methylcellulose is usually in … Continue reading
Viscosity of Cellulose Ether Viscosity is an important parameter of Hydroxypropyl Methylcellulose performance. Different Hydroxypropyl Methylcellulose manufacturers use different methods and instruments to test the viscosity of Hydroxypropyl Methylcellulose currently. The main methods are Haake Rotovisko, Hoppler, Ubbelohde and Brookfield. For the same product, the viscosity has big differences by different test method, some … Continue reading
Water Retention of Cellulose Ether Water retention is an important property of cellulose ether, and it is also a concern of many domestic drymix mortar manufacturers, especially those in the south area with high temperature. Factors that affects the water retention effect of the mortar include the amount of Hydroxypropyl Methylcellulose, the viscosity of … Continue reading

Construction Quality is Easy to Guarantee Different kinds of mortars such as masonry mortar, plastering mortar, ground mortar, block special mortar, etc, have different requirements for special properties such as anti-shrinkage, crack resistance, heat preservation and moisture resistance, … Continue reading
Development Trend of Drymix Powder Mortar in China At the end of the 20th century, China began to introduce Drymix powder mortar technology from abroad, and combined with the source of domestic raw materials, adjusted the formulation of a variety of Drymix powder mortars for different purposes, and achieved results in application of the … Continue reading
Advantages of Drymix Mortar Drymix powder mortar as a substitute for traditional mortar has its own advantages. Construction quality is easy to guarantee Different applications of mortar such as masonry mortar, plastering mortar, ground mortar, block special mortar, etc has different requirements for anti-shrinkage, crack resistance, heat preservation, moisture resistance of the materials, and … Continue reading
Plastering is a process by which coarse surfaces of wall or ceiling roofs are changed or turned or rendered to provide smoothness. In the beginning, wet materials are spread over the block or brickworks and then suitable equipment is used to make the surface smooth level. The prime purpose of plastering is to obtain a … Continue reading
Putty is a thin layer of leveling mortar that can be divided into single-component putty (paste and dry powder) and two-component putty (consisting of powder and liquid) according to its finished form. Dry mortar putty uses organic polymer or inorganic chemicals as bonding agent, and additives such as cellulose ether, thixotropic agent, hydrophobic agent, and … Continue reading
