Kedu uru hydroxypropyl methylcellulose dị?

Hydroxypropyl methylcellulose (HPMC)bụ ihe dị mkpa kemịkal, nke a na-ejikarị eme ihe n'ọtụtụ ebe dị ka ihe owuwu, ọgwụ, nri, ihe ịchọ mma, wdg.

1. Basic e ji mara HPMC

HPMC bụ a mmiri-soluble polima nwetara site kemịkalụ mgbanwe nke eke elu molekul arọ cellulose. O nwere njirimara ntọala ndị a:

Ezi mmiri solubility: HPMC nwere ike igbari na mmiri oyi na-etolite a transperent colloidal ngwọta.

Ngwongwo na-eme ka ọ dị oke mma: Ọ nwere ike ịbawanye viscosity nke mmiri mmiri ma dabara maka usoro nhazi dị iche iche.

Thermal gelation: Mgbe kpochara na ụfọdụ okpomọkụ, HPMC ngwọta ga-gel ma laghachi na a etisasịwo ọnọdụ mgbe jụrụ. Ihe onwunwe a dị mkpa karịsịa na nri na ihe ụlọ.

Nkwụsi ike kemịkalụ: HPMC kwụsiri ike na acid na alkali, ọ naghị enwe ike imebi microbial, ma nwee ogologo oge nchekwa.

Nchekwa na nke na-adịghị egbu egbu: HPMC sitere na cellulose eke, nke na-adịghị egbu egbu na nke na-adịghị njọ, ma na-agbaso usoro nri na ọgwụ dị iche iche.

2. Main ngwa na uru nke HPMC

Ngwa na ụlọ ọrụ ihe owuwu

A na-eji HPMC eme ihe n'ọtụtụ ebe na ụlọ ọrụ ihe owuwu, ọkachasị na ngwa ngwa ciment, ntụ ntụ ntụ, nrapado tile, mkpuchi, wdg. Uru ya bụ isi gụnyere:

Mee ka njide mmiri dịkwuo mma: HPMC nwere ike belata mfu mmiri nke ọma, gbochie mgbawa na ngwa ngwa ma ọ bụ putty n'oge ihicha, ma melite ogo ihe owuwu.

Melite arụmọrụ ihe owuwu: HPMC na-eme ka mmanu ihe dị mma, na-eme ka owuwu dị nro ma na-ebelata ihe isi ike ụlọ.

Melite adhesion: HPMC nwere ike ịkwalite ike njikọ dị n'etiti ngwa agha na mkpụrụ ma melite nkwụsi ike nke ihe ụlọ.

Mgbochi-sagging: Na tile nrapado na putty ntụ ntụ, HPMC nwere ike igbochi ihe onwunwe sagging na melite controllability nke ewu.

Ngwa na ụlọ ọrụ ọgwụ

N'ebe a na-emepụta ọgwụ, a na-ejikarị HPMC eme ihe maka mkpuchi mbadamba, nkwadebe ntọhapụ na mkpuchi capsule. Uru ya gụnyere:

Dị ka ihe mkpuchi mbadamba nkume: Enwere ike iji HPMC mee ihe mkpuchi ihe nkiri iji chebe ọgwụ site na ìhè, ikuku na iru mmiri, ma melite nkwụsi ike ọgwụ.

Ntọhapụ na-adịgide adịgide yana njikwa: N'ime mbadamba ihe ntọhapụ na-adịgide adịgide, HPMC nwere ike ijikwa ọnụego ntọhapụ nke ọgwụ, gbatịa ịdị irè nke ọgwụ, ma melite nnabata nke ndị ọrịa na ọgwụ.

Capsule shei nọchiri anya: Enwere ike iji HPMC mee capsules anụ anaghị eri anụ, nke dabara maka ndị anaghị eri anụ ma ọ bụ ndị na-azụ ahịa nwere mgbochi okpukpe.

Ngwa na ụlọ ọrụ nri

A na-eji HPMC eme ihe n'ọtụtụ ebe na ngwaahịa mmiri ara ehi, ihe ọ beụ ,ụ , ngwaahịa esiri esi, wdg dịka mgbakwunye nri (E464). Uru ya gụnyere:

Thickener na emulsifier: Enwere ike iji HPMC na ihe ọṅụṅụ na ihe oriri iji mee ka viscosity na nkwụsi ike na igbochi stratification.

Mee ka uto dị mma: N'ime ngwaahịa esi nri, HPMC nwere ike ịbawanye ịdị nro nke nri, na-eme ka achịcha na achịcha dị nro na mmiri.

Mee ka ụfụfụ guzosie ike: Na ngwaahịa ice cream na ude, HPMC nwere ike mee ka ụfụfụ kwụsị ma melite ọdịdị ngwaahịa ahụ.

Ngwa na ụlọ ọrụ ịchọ mma

A na-eji HPMC eme ihe na ngwaahịa nlekọta anụ ahụ, ncha ntutu na ntacha eze. Isi uru bụ ndị a:

Mmetụta moisturize: HPMC nwere ike ịmepụta ihe nkiri na-eme ka mmiri dị n'elu akpụkpọ ahụ iji gbochie ikuku mmiri ma mee ka akpụkpọ ahụ dị nro.

Emulsion kwụsie ike: Na lotions na akpụkpọ ude, HPMC nwere ike melite emulsion kwụsie ike na-egbochi mmanụ-mmiri nkewa.

Melite viscosity: Na ncha ntutu na mmiri ịsa ahụ, HPMC nwere ike melite viscosity ngwaahịa ma melite ahụmịhe ojiji.

3. Nchekwa gburugburu ebe obibi na nchekwa nke HPMC

HPMCa na-enweta site na eriri osisi sitere n'okike, nwere ezigbo bioocompatibility, ma na-egbo mkpa nchekwa gburugburu ebe obibi. Isi uru ya bụ ndị a:

Ndị na-adịghị egbu egbu na ndị na-adịghị emerụ ahụ: Ndị ụlọ ọrụ na-ahụ maka nri na ọgwụ akwadoro HPMC maka iji nri na ọgwụ, ma ọ dị oke nchebe.

Biodegradable: HPMC agaghị emetọ gburugburu ebe obibi yana enwere ike imebi ya.

Zute ihe ndị chọrọ ụlọ akwụkwọ ndụ akwụkwọ ndụ: Ngwa nke HPMC na ụlọ ọrụ ihe owuwu kwekọrọ na usoro nchekwa gburugburu ebe obibi nke nchekwa ike na mbelata ikuku, na-ebelata mfu mmiri nke ngwa ngwa ciment, ma na-emeziwanye arụmọrụ ihe owuwu.

HPMC bụ ihe na-arụ ọrụ polymer nke na-arụ ọrụ dị mkpa n'ịrụ ụlọ, ọgwụ, nri na ihe ịchọ mma. Njide mmiri ya magburu onwe ya, ịgbatị, nrapado na nchekwa na-eme ka ọ bụrụ ihe a na-apụghị dochie anya ya. Site na mmepe nke sayensị na teknụzụ, ngwa ngwa nke HPMC ga-aga n'ihu na-agbasawanye, na-enye ihe ngwọta dị mma na gburugburu ebe obibi maka ụlọ ọrụ dị iche iche.
