Hydroxypropyl Methyl Cellulose For Cement Thickening Agent
HPMC(Hydroxypropyl methylcellulose), also known as hypromellose, cellulose hydroxypropyl methyl ether, is obtained by using high purity cotton cellulose as a raw material and special etherification under alkaline conditions.
Hydroxypropyl methylcellulose (HPMC) is odorless, tasteless,non-toxic cellulose ethers produce from natural high molecula and protective colloid properties of surface activity and maintain moisture function properties ect.cellulose through series of chemical processing and achieved.It is white powder with good water solubility. It has thickening, adhesion ,dispersing, emulsifying, film, suspended, adsorption, gel. In the course of construction,HPMC is used for wall putty, tile adhesive, cement mortar, dry mix mortar, wall plaster, skim coat, mortar, concrete admixtures, cement, gypsum plaster, joints fillers, crack filler, etc.
1. Appearance: white or quasi-white powder.
2. Granularity;The pass rate of 100 mesh was more than 98.5%.80 mesh pass rate is 100%.The particle size of special specification is 40 ~ 60 mesh.
3, Carbonization temperature: 280-300 ℃
4. Apparent density: 0.25-0.70 g/cm(usually around 0.5 g/cm), specific gravity: 1.26-1.31.
5, color temperature: 190-200 ℃
6. Surface tension: 2% aqueous solution is 42-56 dyn/cm.
7. Solubility: soluble in water and some solvents, such as appropriate proportion of ethanol/water, propyl alcohol/water, etc.The aqueous solution has surface activity.High transparency, stable performance, different specifications of the product gel temperature is different, the solubility changes with the viscosity, the lower the viscosity, the greater the solubility, different specifications of HPMC performance has a certain difference, the HPMC dissolved in water is not affected by the pH value.
8. HPMC decreases with the decrease of methoxide content, increase of gel point, decrease of water solubility and decrease of surface activity.
9, HPMC also has thickening ability, salt resistance, low ash powder, pH stability, water retention, dimensional stability, excellent film forming, and a wide range of enzyme resistance, dispersion and adhesion.
Hydroxypropyl methylcellulose (HPMC) product are widely used in the construction industry-ceramic tile slurry, dry mixed mortar,crack filler, tile adhesive,self-leveling mortar, thermal insulation mortar,skim coat,putty powder, tile grouts,tile joint filler,decoration mortar,coating glue, cement-based plastering mortar and cement-based ceramic tile adhesive.
