The importance function of HPMC in wet mix mortar mainly has the following 3 aspects: 1. HPMC has excellent water retention capacity. 2. The effect of HPMC on the consistency and thixotropy of wet-mixed mortar. 3. Interaction of HPMC with cement. Water retention is an important property of HPMC, and it is also a property […]

As we all know, the theory of cement’s complete hydration theory requires 26% of the cement’s mass, and the actual water consumption of the mortar greatly exceeds the moisture required for the cement’s hydration in the mortar, which is mainly to meet the needs of construction. The strength of cement stone is mainly related to […]

There are several benefits to using HPMC powder in these construction products. Firstly, it helps to increase the water retention of cement mortar which prevents cracks and improves workability. Secondly, it increases the open time of cement-based products so they can be used longer before they need to be applied or set. Finally, it helps […]

The wall putty is also named skim coat ,it is a decorative and functional trowelling plaster material for interior or external wall building . the function is to remove uneven defects on the surface of the base materials of wall, and eliminate the stress between different coating layers. hydroxypropyl methylcellulose(HPMC) CAS no. : 9004-65-3,is white to […]

Compared with ordinary HPMC, the production of surface-treated HPMC has one more process. We use a cross-linking agent (usually use glyoxal) to treat its surface. The purpose of this step is to enable HPMC to disperse quickly in cold water, rather than dissolving at the beginning. If the added amount of glyoxal is large, the dispersion will […]

What is Wet-mixed mortar ? Wet-mixed mortar is composed of cement, fine aggregate, admixture and water, etc. According to a certain proportion, after being measured and mixed in the mixing station. The wet-mixed mixture is transported to the place of use by a mixer truck, stored in a special container, and used up within the […]

Functions of HPMC in Cement Based and Gypsum Based Products Hydroxypropyl methylcellulose, abbreviated as: HPMC or MHPC. The appearance is white or almost white powder; the main purpose is as a dispersant in the production of polyvinyl chloride, and is the main auxiliary agent for the preparation of PVC by suspension polymerization. In the construction […]

Water Retention Function And Principle Of HPMC Cellulose ether HPMC plays a main role in water retention and thickening in cement mortar and gypsum based slurry, which can effectively improve the adhesion and sag resistance of the slurry. Air temperature, temperature and wind pressure speed will affect the evaporation rate of water in cement mortar […]

cellulose ether manufacturers-HPMC Cellulose Ethers in Cement-based plastering Mortar HPMC Cellulose Ethers used in Cement-based plastering Mortar 1. HPMC can improve the uniformity of plastering mortar, making it easy to coating, at the same time improve the ability of anti-sag. It can also boost liquidity and pumpability of mortar, to improve the work efficiency. 2. […]
