Adding hydroxypropyl methylcellulose to cement can slow down the hydration of cement. So what do you know about its principle? Let’s take a look at hydroxypropyl methyl cellulose to delay the hydration of cement. principle.

The viscosity of hydroxypropyl methylcellulose HPMC, which we usually say, refers to the result of its 2% aqueous solution at a temperature of 20 degrees Celsius. The viscosity of hydroxypropyl methyl cellulose is mainly divided into four categories: low viscosity, medium and low viscosity, medium viscosity and high viscosity. Different viscosities have different uses.

The shallow admixture, which plays a key role in improving the performance of building dry-mix mortar, accounts for more than 40% of the material cost in dry-mix mortar. Most additives in the domestic market are supplied by foreign manufacturers, and the reference dosage of products is also provided by the suppliers.

The characteristics and benefits of hydroxypropyl methylcellulose used in building materials are many. Sleochem gives you a detailed introduction:
Characteristics of hydroxypropyl methyl cellulose

1. The pure hydroxypropyl methylcellulose HPMC has a fluffy visual state and a small bulk density in the range of 0.3–0.4/ml; the adulterated hydroxypropyl methylcellulose HPMC has better fluidity and feel more Shen, there is a clear difference from the authentic appearance.

Hydroxypropyl methylcellulose is a cellulose ether derivative, and its production currently has two process routes: horizontal kettle dry method and vertical kettle solvent method;

Safety and environmental protection exterior insulation materials are the foundation of building construction to ensure disaster prevention and mitigation, energy saving and consumption reduction. With the popularization of construction safety and fire protection knowledge from all walks of life,

Speaking of hydroxypropyl methylcellulose, perhaps the general public do not know what it is, but for the construction industry, most of the first-line construction workers are quite clear.

Daily chemical grade hydroxypropyl methyl cellulose is a synthetic high molecular polymer prepared by chemical modification with natural cellulose as raw material. Cellulose ether is a derivative of natural cellulose. The production of cellulose ether is different from synthetic polymers.
