Hydroxypylththththththylcelllose (hpmc)bụ usoro callivatitional selivative na ọkara nke polymertik contion. A na-ejikarị ya rụọ ọrụ n'ọtụtụ ụlọ ọrụ dịka iwu, ọgwụ, nri, ihe ịchọ mma na corestings. Dị ka nke na-abụghị nke ionic Ether, HPMC nwere ezigbo mmiri solbality, akụrụngwa na-akpụ akpụ ihe nkiri, ngwa ahịa na emulsification, ya mere nwere ezigbo ngwa ahịa bara ụba n'ọtụtụ ubi.
1. Ihe owuwu kemịkalụ na akụrụngwa nke HPMC
A na-enweta usoro molecular nke HPMC site na sel sellose. Mgbe mgbanwe kemịkal, methyl (-ochg) na hydroxypyl (a na-ewebata ìgwè ndị otu na cellulose. Ihe nhazi kemịkalụ ya dị mkpa bụ ihe ndị a:
Molucuse Molecules mejuputara ihe eji eme ihe eji eme ihe eji β-1,4-3,4-1,lycosididic;
A na-ewebata Methyl na Hydroxyppyl n'otu mkpụrụ ndụ cellulose site na mmeghachi omume.
Ihe owuwu ọgwụ a na-enye HPMC ihe ndị na-esonụ:
Mmiri solution: Site na ịchịkwa ogo nke mebere methyl na ìgwè ndị otu hydroxypyl, HPMC nwere ike ịgbanwe ka mmiri ya gharazie isi. N'ikwu okwu, HPMC nwere ike ịhazi ihe ngwọta victous na mmiri oyi ma nwee ezigbo sọlị mmiri.
Mgbanwe viscitty: Enwere ike ịchịkwa viscosity HPMC nwere ike ịchịkwa nke ọma site na ịhazigharị molecular ogo molecular ogo na ogo nke dochie ihe achọrọ iji mezuo ihe dị iche iche achọrọ.
Nguzo ọkụ na-eguzogide: Ebe ọ bụ na Hpmc bụ ihe polymer na-eme, nguzo ya dị mma ma ọ nwere ike ịnọgide na-arụ ọrụ kwụsiri ike n'ime ụfọdụ ọnọdụ okpomọkụ.
Biocom: HPMC bụ ihe na-anaghị egbu egbu na nke anaghị akpata ya, yabụ, ọ masịrị ya na ahụike.
2. Usoro nkwadebe nke HPMC
Thezọ nkwadebe nke HPMC bụ emechara site na mmeghachi omume nke celluse. Usoro ahụ akọwapụtara dị ka ndị a:
Mkpokọta: Nke mbu, gwakọta sekil cellulose nwere ihe mgbaze (dị ka chloroform (nke a na-egbu egbu, wdg) iji gbazee ya n'ime usoro ngwọta sellulose.
Ngbanwe kemịkalụ: Methyl na hydropopyl kemịkagharị (ihe dị ka ogige chloromethyl na Allill mmanya) na-agbakwunye mmeghachi omume.
A na-edozi ọnụ ọgụgụ na nkụ: A na-edozi ọnụ ahịa nke PO site na ịgbakwunye acid ma ọ bụ alkali, dị ọcha, a na-eme ihe na-eme mgbe ahụ mechara nweta hydropyylthylthylthylylthylthyl.
3. Ngwa nke HPMC
Ngwongwo pụrụ iche nke Hpmc na-eme ka ọ rụọ ya n'ọtụtụ ebe. Ihe ndị a bụ ụfọdụ n'ime mpaghara ngwa:
(1) ubi owuwu: A na-eji HPMC ebe niile na ụlọ ọrụ owuwu, tumadi n'ihe owuwu dị ka ciment, ọgwụ, na come. Ọ nwere ike melite ọnya ahụ, adhesion na mmiri mmiri nke ngwakọta ahụ. Karịsịa na ngwa agha a kpọrọ nkụ, HPMC nwere ike imezi arụmọrụ owuwu ahụ, nwekwuo ngwa agha nke ngwa agha, ma zere crackry na ciment slurry n'oge usoro hardganing n'oge usoro.
(2) A na-ejikarị ubi ọgwụ: Na ọgwụ ọgwụ, a na-ejikarị HPMC na-ejikere mbadamba, capsules na ọgwụ mmiri. Dị ka onye na-eme ihe nkiri na-eme ihe nkiri, bụ isiner ma kwụsie ike, ọ nwere ike melite solubality na anụ ọgwụ. Na mbadamba, HPMC enweghị ike ijikwa ọnụego ọgwụ ntọhapụ, kamakwa melite nkwụsi ike nke ọgwụ.
(3) Ubi nri: Enwere ike iji HPMC mee ihe na nhazi nri dika nke ukwu, emunsufier na mma. Dịka ọmụmaatụ, na obere nri na abụba na-enweghị abụba, Hpmc nwere ike inye uto ka mma na udidi ma mee ka nkwụsi ike nke ngwaahịa ahụ. A na-ejikwa ya na nri akpọnwụ iji gbochie nkewa mmiri ma ọ bụ usoro ice.
(4) Cosmetics: na ihe ịchọ mma, a na-eji HPMC eme ihe dị ka ihe na-eto eto na mmiri. O nwere ike ime ka udidi nke ịchọ mma, na-eme ka ha dịkwuo mfe itinye na ịbanye. Karịsịa na ude anụ ahụ, shampoos, ihu ihu ihu na ngwaahịa ndị ọzọ, ojiji nke HPMC nwere ike ime ka obi dị ya mma na nkwụsi ike.
(5) mkpuchi na eserese na eserese na ụlọ ọrụ na-ese, dị ka onye na-agba mmiri, nwere ike idozigharị rhiology nke mkpuchi, na-eme ka mkpuchi ahụ dịkwuo mma. Ọ nwekwara ike ime ka ndị na-eguzogide mmiri na ihe ndị na-emegide ya nke mkpuchi, ma na-abawanye ike na ndọghachi nke mkpuchi.
4. Atụmanya ahịa na mmepe mmepe nke HPMC
Ka ndị mmadụ na-akwụkwu ya na nchedo gburugburu ebe obibi, HPMC, dị ka ihe polymer na-egbu egbu, nwere atụmanya sara mbara. Karịsịa na ụlọ ọrụ ọgwụ, ụlọ ọrụ na-ewu ewu, a ga-esiwanye ngwa nke HPMC. N'ọdịnihu, usoro imepụta nke HPMC nwere ike ịmalite ọzọ, mmụba na mmepụta na mbelata na ọnụ ahịa ga-akwalite ngwa ọrụ ya.
Site na mmepe nke ihe ndị smart na teknụzụ ndị ana-achịkwa, ngwa nke HPMC ọgwụ nnyefe ọgwụ nke ọgwụ na Smart na Smart na Smart ọgwụ ga-abụkwa ebe nyocha. Dịka ọmụmaatụ, enwere ike iji HPMC kwadebe ndị na-ebu ọgwụ ọjọọ na-achịkwa ọrụ mwepụta iji mee ka ọ dị ogologo ma melite nrụpụta.
Hydroxypylthththththylcelllosebụ polymer na arụmọrụ dị mma na ngwa dị iche iche. Na ezigbo mmiri solubity, ike ijikọta viscosity na ezigbo biocombility, HPMC nwere ngwa dị mkpa n'ọtụtụ ubi dị ka owuwu nke HPMC nwere ike ịnọgide na-agbasawanye, atụmanya na-eme ka ọ dị obosara.
