Hydroxypropyl methylcellulose (HPMC)bụ polymer na-abụghị ionic, ọkara sịntetik nke a na-ejikarị eme ihe na ihe owuwu ụlọ, ọgwụ, nri, ihe ịchọ mma na mpaghara mmepụta ihe ndị ọzọ.
1. Njirimara anụ ahụ na nke kemịkal
HPMC bụ polymer nke sitere na cellulose osisi sitere n'okike site na mgbanwe kemịkalụ. Ọ na-adịkarị ọcha ma ọ bụ na-acha ọcha ntụ ntụ, enweghị ụtọ, isi na-adịghị egbu egbu. Ọ nwere ezigbo mmiri solubility na enwere ike ịgbaze na mmiri oyi ma ọ bụ mmiri ọkụ iji mepụta ngwọta colloidal transperent ma ọ bụ ntakịrị turbid. Njirimara solubility ya na-emetụta ogo nke nnọchi, ịdị arọ molecular na okpomọkụ.
2. Ịba ụba
HPMC nwere ihe ndị na-agbapụta nke ọma ma nwee ike ịbawanye viscosity nke ngwọta nke ọma, na-eme ka a na-eji ya dị ka ihe na-esi ísì ụtọ na ụlọ ọrụ dịka ihe owuwu ụlọ, mkpuchi, na ọgwụ. Dịka ọmụmaatụ, na ngwa ngwa ciment, ọ nwere ike ịkwalite ọrụ ya na ịrụ ọrụ ihe owuwu.
3. Njide mmiri
HPMC nwere ike belata evaporation nke mmiri nke ọma ma melite ikike njide mmiri nke ihe. Ihe onwunwe a dị mkpa karịsịa na ụlọ ọrụ ihe owuwu. Dịka ọmụmaatụ, ịgbakwụnye HPMC na simenti ngwa ngwa na ihe ndị dabeere na gypsum nwere ike ịgbatị oge ha mepere emepe, melite ogo ihe owuwu, ma belata mgbawa.
4. Adhesion
N'ihi ezigbo nrapanye ya, a na-eji HPMC eme ihe n'ọtụtụ ebe n'ụdị adhesives tile, mkpuchi, adhesives na ubi ndị ọzọ. Na tile adhesives, ọ nwere ike ịkwalite ike nkekọ ma melite ịdị mma nke ọrụ ihe owuwu.
5. mmanu mmanu
HPMC na-egosiputa mmanu mmanu na ngwọta mmiri, nke na-eme ka ọ bụrụ ezigbo mmanu na mmepụta nke ihe owuwu, mkpuchi, ihe ịchọ mma na mbadamba ọgwụ, na-eme ka arụmọrụ nke ngwaahịa ahụ dịkwuo mma.
6. Ọrụ elu
Ọdịdị molekụla nke HPMC nwere hydrophilic na hydrophobic dị iche iche, nke na-eme ka ọ nwee ọrụ dị elu ma nwee ike ịrụ ọrụ nke emulsification, nkwusioru, mgbasa na ihe ndị ọzọ. Ya mere, a na-ejikwa ya na mkpuchi, emulsion polymerization, detergents na ngwaahịa ndị ọzọ.
7. Nguzogide nnu na nkwụsi ike pH
HPMC bụ ihe na-abụghị ionic polima, ya mere ọ dịtụ kwụsiri ike na electrolytes na ọ dịghị mfe ịkwanye na inorganic salts. Na mgbakwunye, ọ kwụsiri ike na pH nke 3 ruo 11 ma dabara maka mpaghara dị iche iche.
8. Ihe nkiri na-emepụta ihe
HPMC nwere ike ịmepụta ihe nkiri transperent na elu nke ihe dị iche iche nwere ike na mgbanwe dị mma, ya mere a na-eji ya na nkà mmụta ọgwụ (mkpuchi mbadamba nkume), nri (ihe nkiri nchebe), mkpuchi (ihe nkiri na-eme ihe nkiri), wdg.
9. Nguzogide okpomọkụ
HPMC nwere ezigbo nkwụsi ike na-ekpo ọkụ ma ka nwere ike idowe nkwụsi ike ụfọdụ n'usoro na okpomọkụ dị elu. Ọ ga-enweta gelation thermal na mmiri mmiri n'okpuru mmetụta nke okpomọkụ, ya bụ, ọ ga-etolite gel na ụfọdụ okpomọkụ ma gbazee ọzọ mgbe jụrụ oyi. A na-eji ihe onwunwe a eme ihe n'ọtụtụ ebe na ụlọ ọrụ mmepụta ihe, nri na ọgwụ.
10. Biocompatibility na nchekwa
HPMC bụ ihe na-adịghị egbu egbu, ihe na-adịghị agbakasị ahụ na polymer nwere ezigbo biocompatibility, ya mere a na-eji ya eme ihe na ụlọ ọrụ ọgwụ na nri. Dịka ọmụmaatụ, enwere ike iji ya mee ihe n'ime usoro nkwụsị nke ọgwụ, ihe na-eme ka anya na-asọpụta, na ihe ndị na-ekpu nri na emulsifiers.
Mpaghara ngwa
N'ihi ọmarịcha anụ ahụ na kemịkal ya, a na-eji HPMC eme ihe na mpaghara ndị a:
Ụlọ ọrụ ihe owuwu: a na-eji ya eme ihe dị ka ihe na-esi ísì na mmiri na-ejide mmiri maka ciment mortar, tile nrapado, putty powder, na gypsum ngwaahịa iji melite arụmọrụ ụlọ na nrapado.
Ụlọ ọrụ na-emepụta ọgwụ: ejiri ya mee ihe dị ka ihe na-emepụta ọgwụ maka mbadamba mbadamba nkume, ihe ndị na-ahapụ, emulsifiers na stabilizers, wdg.
Ụlọ ọrụ nri: ejiri ya dị ka ihe na-esi nri, emulsifier, na stabilizer maka ice cream, ihe ọṅụṅụ, sauces na ngwaahịa ndị ọzọ.
Ụlọ ọrụ ịchọ mma: ejiri ya na ngwaahịa nlekọta anụ ahụ, ncha ntutu, ntacha eze, wdg, iji nye thickening, emulsification na moisturize mmetụta.
Ụlọ ọrụ mkpuchi: a na-eji ya dị ka ihe na-emepụta ihe na-emepụta ihe na-emepụta ihe na-emepụta ihe na-eme ka mmiri na-ekpuchi mmiri na-eme ka ọ dịkwuo mma na nkwụsi ike nke mkpuchi.
HPMCbụ ihe kacha mma polymer nwere njirimara nke ịgba, njide mmiri, nhazi ihe nkiri, mmanye, na adhesion, na ọ dịghị egbu egbu na adịghị emerụ ahụ, dabara maka ọtụtụ ụlọ ọrụ. A na-eji ya eme ihe n'ọtụtụ ebe na-ewu, ọgwụ, nri, ihe ịchọ mma, mkpuchi na mpaghara ndị ọzọ iji melite ogo ngwaahịa na arụmọrụ. N'ọdịnihu, na ọganihu nke teknụzụ na uto nke ahịa ahịa, ngwa ngwa nke HPMC nwere ike gbasaa ma rụọ ọrụ dị mkpa karị.
