Ọtụtụ isi ihe na-emetụta njide mmiri nke hydroxypropyl methylcellulose

Hydroxypropyl methylcellulose (HPMC) bụ ether cellulose na-abụghị ionic nke sitere na cellulose polymer eke sitere na usoro kemịkalụ. Ha bụ ntụ ntụ ọcha na-enweghị isi, nke na-enweghị ụtọ na nke na-adịghị egbu egbu nke na-adaba n'ime ngwọta colloidal doro anya ma ọ bụ ntakịrị urukpuru na mmiri oyi. Ọ nwere ndim, njide, na-achụsasị, emulsifying, film-akpụ, suspending, adsorbing, gelling, elu-arụ ọrụ, mmiri na-ejigide na-echebe colloid Njirimara. Enwere ike iji Hydroxypropyl methyl cellulose na methyl cellulose mee ihe na ihe owuwu ụlọ, ụlọ ọrụ agba, resin sịntetik, ụlọ ọrụ seramiiki, ọgwụ, nri, textile, ọrụ ugbo, kemịkalụ kwa ụbọchị na ụlọ ọrụ ndị ọzọ.

Ihe ndị a na-emetụtakarị njide mmiri nke hydroxypropyl methylcellulose HPMC ngwaahịa n'onwe ya:

1. Ọnụ ego nke hydroxypropyl methylcellulose HPMC gbakwunyere na-abawanye ụba nke cellulose ether HPMC gbakwunyere, ọnụ ọgụgụ dị elu nke njide mmiri na-eme ka ọ dịkwuo mma. N'ihe dị iche iche nke 0.25-0.6% mgbakwunye, ọnụ ọgụgụ njide mmiri na-abawanye ngwa ngwa na mmụba nke mgbakwunye ego; mgbe ego mgbakwunye na-abawanye, mmụba na-emekarị nke njide mmiri na-ebelata.

2. HPMC viscosity nke hydroxypropyl methylcellulose Mgbe viscosity nke HPMC na-abawanye, ọnụ ọgụgụ njide mmiri na-abawanye; mgbe viscosity rutere n'ogo ụfọdụ, mmụba nke njide mmiri na-eme ka ọ dị nro.

3. Hydroxypropyl methylcellulose HPMC thermal gel okpomọkụ dị elu okpomọkụ gel okpomọkụ, nnukwu njigide mmiri; ma ọ bụghị ya, obere njide mmiri.

4. Hydroxypropyl methylcellulose HPMC homogeneity HPMC nwere otu mmeghachi omume, metoxyl na hydroxypropoxyl na-kesara ọbụna, na mmiri njigide ọnụego dị elu.
