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

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
The development of dry mortar has changed many times since its inception. In the 1960s and early 1970s, the dry powder mortar factory in Europe adopted a horizontal process, which arranged the raw material warehouse one by one on the ground. The raw materials were first stored in the silos through the lifting equipment, and … Continue reading
Basic Situation of European Dry Mortar In the 1950s and 1960s in Europe, especially in Germany, the demand for the new building materials and technologies in the construction industry grew rapidly, but due to labor shortage at that time(especially the lack of experienced skilled workers), labor costs were very expensive. The construction period has … Continue reading
