Application of hydroxypropyl methyl cellulose (HPMC) in detergent

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 role of several properties of hydroxypropyl methylcellulose in dry mortar

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 methylcellulose HPMC is used as a dispersant, thickener and binder in construction treatment

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;

Characteristics of hydroxypropyl methylcellulose high temperature technology

Hydroxypropyl methyl cellulose manufacturer, focusing on the production and sales of cellulose. The characteristics of hydroxypropyl methyl cellulose high-temperature technology: It may be a temperature-sensitive gelling cellulose ether, and hydroxypropyl methyl cellulose can be used in processed foods. For example, it is known that cheese, during heating, may be added to cellulose ether when its shape retention improves.

High-quality hydroxypropyl methylcellulose water retention

High-quality hydroxypropyl methyl cellulose can be uniformly and effectively dispersed in cement mortar and gypsum-based products, and wrap all solid particles, and form a layer of wetting film. The moisture in the base is gradually released over a long period of time.

How to tell if hydroxypropyl methyl cellulose ether is fake?

1. The pure hydroxypropyl methyl cellulose HPMC looks fluffy and has a small bulk density, ranging from 0.3-0.4/ml; while the fake hydroxypropyl methyl cellulose has better fluidity and feels better It is heavy, which is significantly different from the original appearance.

Precautions when preparing hydroxypropyl methyl cellulose solution

1. Products without surface treatment (except hydroxyethyl cellulose) shall not be directly dissolved in cold water.

2. It must be slowly sifted into the mixing container. Do not add the product that has formed into lumps into the mixing container directly.
