The Effect of Hydroxypropyl Methyl Cellulose(HPMC) on the Setting Time of Concrete

By |2023-05-12T02:33:10+00:00May 12th, 2023|Industry knowledge|

The setting time of concrete is mainly related to the setting time of cement, and the influence of aggregate is not great. Therefore, the effect of HPMC on the setting time of underwater non-dispersible concrete mixture can be studied through the setting time of mortar. Because the setting time of mortar is affected by water.

Hydroxypropyl methylcellulose(HPMC) is easily soluble in cold water, but it will encounter difficulty in dissolving in hot water. But its gelation temperature in hot water is significantly higher than that of methyl cellulose. The solubility in cold water is also greatly improved compared with methyl cellulose. Hydroxypropyl methylcellulose(HPMC) is stable to acid and alkali, and

Ⅰ. Water-resistant putty for interior and exterior walls: 1. Excellent water retention, which can prolong the construction time and improve work efficiency. High lubricity makes construction easier and smoother. Provides a smooth and even texture for a smoother putty surface. 2. High viscosity, generally between 100,000 and 150,000 sticks, makes the putty more adhesive to

Talking about Hydroxypropyl Methyl Cellulose Ether (HPMC) for Dry Powder Mortar(2)

For the same product, the viscosity results measured by different methods are very different, and some even double the difference. Therefore, when comparing viscosity, be sure to do it between the same test methods, including temperature, rotor, etc. For particle size, the finer the particle, the better the water retention. After the large particles of

Why add hydroxypropyl methyl cellulose (HPMC) to mortar?

This article mainly introduces hydroxypropyl methyl cellulose in mortar. The production process of hydroxypropyl methylcellulose is mainly a polysaccharide-based ether product produced by alkalinisation and etherification of cotton fibres (domestic). It is not charged itself. And it does not react with the charged ions in the gelling material, making it stable. The price of HPMC

Types of cellulose ether and mechanism of action (II)

The previous article introduced the mechanism of action of cellulose ethers. And the next article will introduce some basic cellulose ether classifications. 1.1.1 Methyl cellulose (MC) molecular formula \[C6H7O2(OH)3-h(OCH3)n\]x Refined cotton is treated with alkali and made into cellulose ether after a series of reactions with methane chloride as the etherizing agent. The general degree
