What kind of viscosity is suitable for the hpmc in the caulk & filling agent?

Ceramic tile grouts have the advantages of waterproof, mildew-proof, scrubbing resistance and rich color. 1. Waterproof function: The ceramic tile surface and the filler filling between the ceramic tile seams form a complete waterproof layer, which avoids water seeping into the wall from the brick seams and causes the ceramic tile to fall off. 2. [...]

What is hydroxypropyl methylcellulose HPMC ?

Hydroxypropyl methylcellulose HPMC is refined from cotton by alkalization, and propylene oxide and methyl chloride are used as etherifying agents to form a nonionic cellulose mixed ether through a series of reactions. Hydroxypropyl methylcellulose is a nonionic cellulose ether that has a white appearance and is odorless and tasteless. The degree of substitution is generally [...]

How to choose the right hydroxypropyl methylcellulose

The relationship between water retention and viscosity of hydroxypropyl methylcellulose is not a proportional relationship within a certain viscosity range, but also depends on the practical application of the product. Relatively speaking, when hydroxypropylmethylcellulose has a viscosity of more than 100,000, the difference in water retention between 100,000 viscosity and 200,000 viscosity is not large. [...]

Application characteristics of cellulose ether in cement products

Cellulose ether is a multi - purpose additive that can be used in cement products. Cellulose ether (abbreviated as CE, the abbreviation of Cellulose Ether) is formed by etherification of cellulose or one or more etherifying agents and dry grinding. Cellulose ethers can be divided into ionic and nonionic types. Among them, nonionic cellulose ethers [...]
