HPMC for Ceramic tile adhesive
Hydroxypropyl methyl cellulose can make dry mix ingredients easy to mix, do not produce clumps, thus saving working time, due to faster and more efficient application, can improve the construction and reduce costs. By extending the cooling time, the efficiency of tiling is improved. Provides excellent adhesion. Be in especially in adornment sex construction, use as to stick ceramic tile, marble, plastic adornment, stick intensity is high, still can reduce cement dosage.
Hydroxypropyl methyl cellulose (HPMC) Advantages:
Water soluble and thickening ability: this product is soluble in cold water, and it can form transparent sticky solution. In organic solvent of dissolved: because it contains a certain amount of hydrophobic methoxyl, this product is soluble in some organic solvent; it is also soluble in water and organic mixed solvent.
Hydroxypropyl methyl cellulose (HPMC) salt resistance: because ion and the polyelectrolytein exsist in this product, its metal salt or organic electrolyte aqueous solution is stable.
Surface activity: HPMC for daily chemical aqueous solution has the surface activity, ensuring its emulsification, protective colloid and relative stability.
Low ash content: because ion exist in this product, in preparation process we can use hot water washing for effective refinement, so its ash content is very low.
pH stability: HPMC aqueous solution viscosity in the range of pH3.0-11.0 is more stable.
Water retention effect: this product is hydrophilic and its solution has high viscosity.
Film-forming property: HPMC can generate strong pliable and transparent sheet, which has the good oil resistance to ester performance.
Hydroxypropyl methyl cellulose is divided into two kinds of ordinary hot soluble cold water instantly soluble. Hydroxypropyl methyl cellulose uses are 1, Gypsum series In the gypsum series of products, cellulose ethers are mainly used to retain water and increase smoothness. Together they play a cer
