Influence of the indicators of HPMC on dry-mix mortar

By |2022-05-18T01:58:01+00:00May 18th, 2022|Product Applications|

As the main admixture in construction dry-mix mortar products, hydroxypropyl methyl cellulose plays a key role in the performance and cost of dry-mix mortars. Currently, the majority of cellulose ether products are used in construction materials worldwide. An important property of cellulose ethers is their water retention in construction materials. Without the addition of cellulose

Generally speaking, the higher the viscosity, the better the water retention effect. However, the higher the viscosity, the higher the molecular weight of MC, and its solubility will be reduced accordingly, which has a negative impact on the strength and construction performance of mortar. The higher the viscosity, the more obvious the thickening effect on

For particle size, the finer the particle, the better the water retention. When large particles of cellulose ether come into contact with water, the surface immediately dissolves and forms a gel to wrap the material and prevent water molecules from continuing to penetrate. Sometimes it is not evenly dispersed and dissolved even after long time

HPMC Chinese name hydroxypropyl methyl cellulose, non-ionic, is often used as a water retention agent in dry-mixed mortar, and is the most commonly used water retention material in mortar. HPMC production process is mainly cotton fiber (domestic) through alkylation, etherification and generated a polysaccharide-based ether products. It is not charged itself and does not react

HEC in toothpaste

By |2022-05-13T06:14:26+00:00May 13th, 2022|Product Applications|

Advantages of HEC application in toothpaste: (1)Combined with CMC, to meet the requirements of modern toothpaste production process, so that the time of wetting, hydration and expansion of adhesive is shorter than in the past, suitable for dry production process. (2) The particle size is less than CMC, and the paste appearance is bright, delicate

What role does cellulose ether play in dry mortar?

By |2022-05-09T02:38:10+00:00May 9th, 2022|Product Applications|

Cellulose ether is a synthetic polymer made of natural cellulose as raw material by chemical modification. Cellulose ether is a derivative of natural cellulose, cellulose ether production and synthetic polymers are different. Its basic material is cellulose, a natural polymer compound. Due to the particularity of natural cellulose structure, cellulose itself has no ability to

Common methods of dissolving HPMC

HPMC without surface treatment do not dissolve in hot water above 85, but can swell and disperse in hot water. Usually, dissolving HPMC  the following methods are used: 1. Conventional methods. Take about 1/5 to 1/3 of the required amount of hot water and stir to make the added product expand completely. Then add the

Hydroxypropyl methyl cellulose is divided into two kinds of ordinary hot soluble cold water instantly soluble. Hydroxypropyl methyl cellulose uses are: 1.Gypsum series In the gypsum series of products, cellulose ethers mainly use to retain water and increase smoothness. Together they play a certain alleviating role. It addresses concerns about drum cracking and initial strength
