Construction chemicals hydrocypropyl methyl cellulose hpmc

Construction chemicals hydrocypropyl methyl cellulose hpmc
hydroxy propyl methyl cellulose HPMC powder from china
Hydroxy propyl methyl cellulose (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.
Physicochemical Property

2. particle size: the passing rate of 80 mesh is 100% the passing rate of 100 mesh is more than 99.5%
3. Charring density:280-300℃
4. Apparent density: 0. 25-0.70g/cm(usually around 0.5g/cm), the proportion is 1.26-1.31
5. Thermochromic temperature: 190-200℃
6. Surface tension: 2% of aqueous solution is 42-56dyn/cn.
HPMC hydroxypropyl methylcellulose in building materials
1. Cement mortar: Improve the dispersion of cement-sand, greatly improve the plasticity and water retention of the mortar, and have an effect on preventing cracks, which can enhance the 
strength of the cement.
2. Tile cement: improve the plasticity, water retention of the pressed tile mortar, improve the bonding strength of the tile, prevent powdering.
3. Gypsum coagulation slurry: Improves water retention and processability, and improves the adhesion to the substrate.
4. Seam cement: added to the joint cement for gypsum board to improve fluidity and water retention.
5. Coatings: As a plasticizer for latex coatings, it has an effect on improving the handling properties and fluidity of coatings and putty powder.
