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;

Hydroxypropyl methyl cellulose manufacturer, focusing on the research and development, production and sales of hydroxypropyl methyl cellulose, latex powder and cellulose ether. What factors affect the dissolution time of hydroxypropyl methylcellulose cold-water quick-dissolving product (with S),

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 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.

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.

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.

The importance of the mortar retention of hydroxypropyl methyl cellulose in the mortar is why it has high requirements for water retention. Hydroxypropyl methyl cellulose is a kind of non-ionic cellulose mixed ether. A semi-synthetic, inactive, viscoelastic polymer, often used in ophthalmology as a lubrication department, or as an excipient or excipient in oral medicine, it can be said that it is common in various kinds of commodities.

Hydroxypropyl methyl cellulose (HPMC) is a natural polymer materials as raw materials,through a series of chemical processing and prepared non-ionic cellulose. It contains almost methyl cellulose(MC) of all the performance, your first choice for production of high quality building materials additives.To meet the needs of environmental protection,
