Industrial Grade Cellulose Ether HPMC Powder Construction Building Raw Material

Construction Building Raw Material Industrial Grade Cellulose Ether HPMC Powder

JF HYDROXYPROPYL METHYLCELLULOSE POWDER Product Introduce:

Product Description:

Hydroxy propyl 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.

Hydroxypropyl Cellulose Function And Application:

Typical Applications:

Cement Plaster / Dry mix mortar
•Increased water demand: increased open time, expanded spry area and more economical formulation.
•Easier spreading and improved sagging resistance due to improved consistency.
•Easy dry mix formula due to cold water solubility: lump formation can be easily avoided, ideal for heavy tiles.
•Good water retention: prevention of fluid loss to the substrates, the appropriate water content is kept in mixture which guarantees longer concreting time.

Tile Adhesives
•Improved adhesion and sliding resistance: especially for heavy tiles.
•Better workability: lubricity and plasticity of plaster is ensured, mortar can be applied easier and quicker.
•Good water retention: prolonged opening time will make tiling more efficient.

Exterior Insulation and Finish System ( EIFS )
•Reduced air entrancement and water uptake.
•Improved adhesion.
•Good wetting ability for EPS board and substrate.

Wall putty/Skim coat
•Increased mortar yield: depending on the weight of the dry mixture and appropriate formulation ,HPMC can increase the mortar volume.
•Water retention: maximized water content in slurry.
•Anti-sagging: when spreading a thicker coat corrugation can be avoided.
Filler
•Water retention ensures prolonged work time.
•Sag resistance: improved mortar bonding ability.
•Better workability: proper thickness and plasticity.

Self-leveling
•No effect on slurry fluidity with low viscosity
HPMC, while its water retention characteristics improve the finish performance on the surface.
•Protection from water exudation and material sedimentation.

Phusical & Chemical Peoperties:

* Particle size: 98.5% passes through 100 mesh; 100% passes through 80 mesh.
* Charring temperature: 280-300ºC.
* Bulk density: 0.25-0.70 g/cm3 (Usually around 0.5 g/cm3 )
* Real specific gravity: 1.26-1.31.
* Browning temperature: 190-200ºC.
* Surface tension: (2% water solution) 42-56dyn.cm.
* Properties: Dissolved in water and some organic solvent such as ethanol. propyl alcohol. ethylene chloride, the water solution is of surface activity. It is a nonionic surface active agent. Gelation temperature is different for different grades. For example, among 60RT Hydroxypropyl Methylcellulose, 60 is gelation temperature, Namely, 2% water solution will form gelation at 60%
