Hydroxypropyl content and viscosity, most users are concerned about these two indicators. With high hydroxypropyl content, water retention is generally better. Large viscosity, water retention, relatively (but not absolute) is better, and high viscosity, better use in cement mortar.

Hydroxypropyl methyl cellulose is a water-soluble polymer compound, also known as water-soluble resin or water-soluble polymer. It increases the consistency of the mixture by increasing the viscosity of the mixing water. It is a hydrophilic polymer material. It can be dissolved in water to form a solution or dispersion. Experiments show that when the amount of naphthalene-based superplasticizer increases, the incorporation of water-reducing agent will reduce the dispersion resistance of fresh cement mortar.

The hydroxypropyl cellulose ether hpmc is provided with a water-repellent and thickening-imparting cellulose ether.

You may be unfamiliar when it comes to hydroxypropyl methyl cellulose, but when it comes to cement, mortar, and concrete, everyone is familiar with it. Hydroxypropyl methyl cellulose is an important additive in cement, mortar, and concrete. Let’s take a look at hydroxypropyl. What are the effects of methyl cellulose on the properties of cement, mortar and concrete.

Putty powder is generally 100,000 yuan, but the mortar is more demanding, and it takes 150,000 yuan to work. Moreover, the most important role of HPMC is water retention, followed by thickening. In putty powder, as long as the water retention is good and the viscosity is lower (70,000-80,000),

The transparency and performance of hydroxypropyl methyl cellulose are relatively stable. The performance requirements of hydroxypropyl methyl cellulose have relatively different requirements. For example, what is the solubility of hydroxypropyl methyl cellulose products?

Hydroxypropyl methyl cellulose is a propylene glycol ether of methyl cellulose, in which both hydroxypropyl and methyl are combined with the anhydrous glucose ring of cellulose by ether linkages. It is a non-ionic cellulose ether and is easily dispersed in In cold water, the solution can form a thin film after drying. The aqueous solution is characterized by a pseudoplastic fluid and has the effect of mixing. After heating, a reversible thermal gel is formed.

The water retention of dry mortar refers to the ability of the mortar to retain and lock moisture. The higher the viscosity of hydroxypropyl methyl cellulose ether, the better the water retention. Since the cellulose structure contains hydroxyl and ether bonds, the oxygen atoms on the hydroxyl and ether bond groups associate with water molecules to form hydrogen bonds, so that free water becomes bound water,

Hydroxypropyl methyl cellulose HPMC is used as a dispersant, thickener and binder in construction treatment, and is mainly used in the molding of cement mortar and gypsum products. It is used in cement mortar to increase its adhesion, reduce flocculation, improve viscosity and shrinkage, and have water retention. Reduce the moisture loss and strength of the concrete surface, prevent cracks and weathering of water-soluble salts;
