With the increase of cement dosage, the tensile adhesive strength of ceramic tile after water immersion treatment increases, while the tensile adhesive strength of thermal aging treatment decreases with the increase of excessive cement dosage. The optimal dosage of P· 042.5 cement is 40%.

Appearance: HPMC is a nonionic cellulose ether, white grayish-white powder or granule,odorless and flavorless, soluble in cold water, glacial acetic acid, ethanol, methanol and propylene glycol, slightly soluble in acetone depending on the degree of substitutions

Hydroxypropyl methyl cellulose (HPMC) product characteristics
1. Properties: This product is a white powder, and is odorless, tasteless and non-toxic.

Regarding the problem that putty powder is easy to powder, or the strength is not up to anything. It is known that cellulose ether needs to be added to make putty powder, and many users do not add redispersible latex powder.

The polymer film formed by Redispersible polymer powder has good flexibility. A film is formed in the gaps and surfaces of the cement mortar particles to form a flexible connection. So that the brittle and hard cement mortar becomes elastic. The mortar added with Redispersible polymer powder is several times higher in tensile and flexural resistance than ordinary mortar.

Gypsum based and gypsum-lime based machine spray plasters are mixed and applied in continuously working plastering machines. They are used for a highly efficient coating of walls and ceilings and applied in one layer (ca. 10 mm thick).

SLEOCHEM cellulose ethers are essential components of successful cement-based render formulations. render must retain enough water for proper setting of the cement and to achieve high mechanical strength. Celotech cellulose ethers improve water retention of cement-based render and offer these additional advantages:

Cellulose ether is a common additive in dry mortar, which plays a very important role.

MC is methyl cellulose: is refined cotton after alkali treatment, methane chloride as etherifying agent, through a series of reactions to make cellulose ether. Generally, the degree of substitution is 1.6~2.0, and the solubility varies with the degree of substitution. Belongs to nonionic cellulose ether.
