Dissolving process:
HPMC will agglomerate when directly added to water and then dissolve. In this
way,it dissolves very slow and hard. Suggested methods are as followers:
1) In hot water: add water in container to 1/3 or 2/3 of its content, heated
to over 80°C, because HPMC doesn't dissolve in hot water, it uniformly
disperses in hot water; add cool water or ice to the residual content, stir
and cool down the mixture
2) Powder combination: mix HPMC with identical volume of other powder,
disperses them sufficiently then add water to the mixture result HPMC
dissolves without agglomeration
3) Organic solvent wet: dispersed or wet with organic solvents, such as
ethanol, glycol or oil, then add water can cause HPMC completely dissolves
Applications:
HPMC is mainly used as dispersant in the production of PVC and as thickener,
stabilizer, emulsifier, excipient, water retention agent, film-forming agent in
petrochemical, building materials, agrochemical, ink, printing and dyeing of
textile, paper making and cosmetics.
Transportation and storage:
1) Keep dry where good ventilated
2) Do not wet and keep away from sunshine during transportation
Packing:
25kg/multi-paper bag or kraft paper bag
