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.

Hydroxypropyl methylcellulose for construction prevents excessive absorption of water by the substrate, and the water should be retained in the plaster as much as possible during the period when the gypsum is solidified.

Hydroxypropyl methylcellulose is now used in all walks of life. What kind of raw material is it?

Hydroxypropyl methylcellulose has its unique properties in the application of building materials, from mixing to dispersion to construction, as follows:

1. The quality of hydroxypropyl methylcellulose produced in horizontal and vertical kettles

Soluble in water and some organic solvents

It is soluble in cold water, and its maximum concentration is only determined by viscosity. The solubility changes with viscosity. The lower the viscosity, the greater the solubility.

Regarding the gel temperature of hydroxypropyl methyl cellulose HPMC, many users seldom pay attention to the problem of hydroxypropyl methyl cellulose gel temperature. Nowadays, hydroxypropyl methyl cellulose is generally distinguished by viscosity, but for For some special environments and special industries, it is not enough to reflect the viscosity of the product. The following briefly introduces the gel temperature of hydroxypropyl methylcellulose.
