Hydroxypropyl methylcellulose (HPMC) bụ polymer vasatail ewepụtara site na cellulose, polysaccharide na-emekarị nke a na-ahụ na mgbidi cell nke osisi. A na-ejikarị ya na ụlọ ọrụ dị iche iche dịka ọgwụ, nri, ihe ịchọ mma, ihe owuwu, na ihe ndị ọzọ n'ihi ihe ndị pụrụ iche ya.
A na-emepụta HPMC site na cellulose na-emezi kemịkal site na mmeghachi omume etherification. Kpọmkwem, a na-emepụta ya site n'ịgwọ cellulose na ngwakọta propylene oxide na methyl chloride iji webata hydroxypropyl na methyl otu n'ime ọkpụkpụ azụ cellulose. Usoro a na-ebute polymer na-agbaze mmiri nwere ihe ndị dị mma ma e jiri ya tụnyere cellulose nke ala.
Usoro mmepụta:
Mmepụta nke HPMC gụnyere ọtụtụ usoro:
Cellulose Sourcing: Cellulose, nke na-esite na pulp osisi ma ọ bụ owu, na-eje ozi dị ka ihe mmalite.
Etherification: Cellulose na-enweta etherification, ebe ọ na-emeghachi omume na propylene oxide na methyl chloride n'okpuru ọnọdụ a na-achịkwa iji webata hydroxypropyl na methyl otu.
Nchacha: Ngwaahịa a na-enweta na-enweta usoro nchacha iji wepụ adịghị ọcha na ngwaahịa ndị achọghị.
ihicha na igwe igwe: A na-akpọchaa HPMC ahụ emechara ka ọ bụrụ ntụ ntụ ma ọ bụ granules dị mma, dabere na ngwa achọrọ.
HPMC na-egosipụta ọtụtụ akụrụngwa, na-eme ka ọ dabara maka ngwa dị iche iche:
Mmiri Solubility: HPMC bụ soluble na mmiri oyi, na-akpụ ngwọta doro anya, viscous. Enwere ike idozi solubility ahụ site n'ịgbanwe ogo nnọchi anya (DS) nke otu hydroxypropyl na methyl.
Ịmepụta ihe nkiri: Ọ nwere ike ịmepụta ihe nkiri na-agbanwe agbanwe ma na-ejikọta ọnụ mgbe a mịrị amị, na-eme ka ọ dị mma maka mkpuchi mkpuchi na ụlọ ọrụ ọgwụ na ụlọ ọrụ nri.
Ọkpụkpụ: HPMC bụ onye na-emepụta ihe na-arụ ọrụ nke ọma, na-enye njikwa viscosity n'ụdị dị iche iche dị ka lotions, ude, na agba.
Nkwụsi ike: Ọ na-egosipụta nkwụsi ike kemịkalụ dị mma na iguzogide mmebi microbial.
Ndakọrịta: HPMC dakọtara na ọtụtụ ihe ndị ọzọ, gụnyere surfactants, salts na preservatives.
HPMC na-achọta ọtụtụ ngwa n'ofe ụlọ ọrụ dị iche iche:
Ọgwụ: A na-ejikarị ya eme ihe dị ka ihe nchikota, ihe mkpuchi ihe nkiri, ihe ngbanwe viscosity, na matrix ntọhapụ na-adịgide adịgide na nhazi mbadamba.
Ụlọ ọrụ nri: HPMC na-eje ozi dị ka onye na-agbapụta, stabilizer, na emulsifier na ngwaahịa nri dị ka sauces, uwe, na desserts.
Mwube: N'ime ụlọ ọrụ ihe owuwu, a na-eji HPMC eme ihe dị ka ihe siri ike na ngwaahịa ndị sitere na ciment, na-emeziwanye arụmọrụ na nrapado.
Ngwaahịa nlekọta onwe onye: A na-ahụ ya na ihe ịchọ mma, shampoos, na nsí eze dị ka ihe na-eme ka ọ dị arọ, emulsifier, na ihe nkiri mbụ.
Agba na mkpuchi: HPMC na-eme ka njirimara rheological nke agba na mkpuchi dịkwuo mma, na-eme ka ngwa na arụmọrụ ha dịkwuo mma.
HPMC, nke sitere na cellulose sitere na mmeghachi omume etherification, bụ polymer na-agbanwe agbanwe nwere ngwa dị iche iche n'ofe ụlọ ọrụ dị iche iche. Ngwongwo ya pụrụ iche, dị ka mmiri solubility, ikike imepụta ihe nkiri, na ihe na-eme ka ọ dị arọ, na-eme ka ọ dị mkpa na ọgwụ, nri, ihe owuwu, na ngwaahịa nlekọta onwe onye.
