Hydroxypylththththththylcelllose (hpmc) bụ ihe polymer dị mkpa nke a na-ejikarị emepụta ihe owuwu na ihe omume dị ka adhaesives na larịị. HPMC nwere ezigbo nmechi, njikọta mmiri, nke na-emepụta ihe na akụrụngwa na-akpụ akpụ ihe nkiri, nke na-eme ka ọ rụọ ọrụ dị mkpa na ọnọdụ ngwa dị iche iche.
1. Ihe owuwu kemịkalụ na akụrụngwa nke HPMC
HPMC bụ ihe na-enye mmiri cellulose nwetara site na modenification eke sellulose, gụnyere hydroporsyylation na methylation. Mgbe mgbanwe ndị a gasịrị, HPMC nwere hydrophilic otu na hydrophobic otu na-arụ ọrụ na-efe efe, si otú a na-egosi mkpaso, viscosity na Njirimara Gel. Uru nke ihe owuwu a bu na solublition nke mgbanwe HPMC na onodu di iche iche, ya mere, o nwere ike idobe arusi ike na oke okpomoku. Na mgbakwunye, HPMC nwere ezigbo sosdọ aka na mmiri ma nwee ike ịmalite ngwọta carbidal, nke dị oke mkpa maka imezi arụmọrụ nke ngwaahịa nrapado.

HPMC na-arụ ọrụ dị ka nke na-emegharị na mmiri na-agbachitere, na-ejide na ihe nrapado adịghị nfe n'oge a na-asa mmiri, nke na-enyere aka igbochi mmiri ngwa ngwa, si otú a na-eme ka ihu igwe na-agbanwe agbanwe. Ngwongwo a dị mkpa karịsịa na ngwa n'èzí, n'ihi na okpomọkụ na iru mmiri nke gburugburu ebe obibi na-agbanwe nke ukwuu, na HPMC nwere ike ịkwalite nguzogide na-eguzogide ndụ ya ma gbasaa ndụ ya.
3. Ngwa nke HPMC na ala
Ọrụ bụ isi nke akara bụ iji mejupụta oghere ma gbochie introsion nke ikuku na mmiri, si otú a na-enyere aka rụọ ihe owuwu ụlọ ọrụ. Ngwa nke HPMC na ọkwa na-eweta uru dị mkpa.
Melite Njirimara Ngwuputa
HPMC nwere ezigbo usoro ihe nkiri na-akpụ akpụ, nke dị oke mkpa maka ngwa nke akara. Mgbe etinyere na a na-etinye ihe dị larịị, HPMC na-etolite edo edo na free fim nwere ike ime ka mmiri dị iche na ikuku iji hụ na arụmọrụ ahụ. Karịsịa maka ngwa ndị na-ahụ maka nkwonkwo ma ọ bụ gburugburu iru mmiri nke HPMC nwere ike ime ka nsonaazụ ya dị mma.
Melite mgbasa na nkwanye ugwu
HPMC nwere ike ịkwalite ngbanwe nke ọkwa, na-enye ha ohere ịnọgide na-agbanwe agbanwe na nkwụsi ike mgbe ị na-emegharị obere ma ọ bụ mgbanwe okpomọkụ na ụlọ. Inictity a dị ezigbo mkpa maka itinye akwụkwọ nke ihe dị iche iche nke ihe dị iche iche (dịka ihe nwere ike igbochi ihe dị iche iche ma ọ bụ daa n'ihi mmetụta na-adịgide adịgide na nke kwụsiri ike.
Na-eme ka mmiri sie ike
Ngwongwo mmiri HPMC dị mma na njigide mmiri nke nwere ike belata infortration mmiri ma melite arụmọrụ mgbochi mmiri nke akara mmiri. Ahịrị na-eji na gburugburu iru mmiri na-enwe nsogbu nke mmiri mmiri, na mgbakwunye nke HPMC nwere ike ime ka ọ dị mma arụmọrụ mmiri nke akara, si otú ahụ.
4. Njirimara ndị ọzọ na uru gburugburu ebe obibi nkeHpmc
Ezigbo njirimara gburugburu ebe obibi
HPMC, dị ka okike cellulose eke, nwere ezigbo biodegrad na-abụ ihe gburugburu ebe obibi ndị ọzọ. Na mgbakwunye, HPMC bụ ihe na-adịghị egbu egbu na adịghị emerụ ahụ, yabụ na-emerụ ahụ ike mmadụ, yabụ, ọ nwere uru bara uru na nchebe na nchekwa. N'ọnọdụ ngwa ngwa, dị ka akara ihe maka ịchọ mma ụlọ na akụrụngwa nri, HPMC abụrụla nhọrọ kachasị mma n'ihi nchekwa ya.
Gbanwee usoro nke ngwa ngwa
HPMC nwere ezigbo ntuli aka na nkwụsi ike ikuku, ma nwee ike ịnọgide na-arụ ọrụ siri ike n'okpuru ọnọdụ gburugburu ebe obibi dị iche iche. Ma na oke oyi ma ọ bụ nke dị ọkụ ma na-ekpo ọkụ, HPMC nwere ike ịme ọrụ ya na adresives na larịị, na-eme ka ọ gbanwee ihe owuwu na mkpa dị iche iche.
5. Atụmanya ọdịnihu
Na mmụba na-abawanye maka gburugburu ebe obibi, ihe na-adịgide adịgide na nke na-enweghị ihe owuwu na ụlọ ọrụ ụlọ ọrụ, atụmanya ngwa nke Hpmc sara mbara. N'ọdịnihu, na-enwe ọganihu nke teknụzụ, usoro nrụpụta na ọnụego nrụpụta nke HPMC ga-ebugharị ya nke ọma, nke ga-agbasawanye ahịa ya na adhesives na larịị. Na mgbakwunye, enwere ike ịkacha arụmọrụ HPMC site na ijikọta ihe mgbakwunye ndị ọzọ ọrụ, dịka antibacterial na akụrụngwa ọkụkọ, iji zute mkpa ngwa dị iche iche.
Ngwa nkeHpmc Na adhesives na larịịs na-egosipụta n'ụzọ zuru oke dị ka isi ihe dị mkpa. Eture ya, njigide mmiri, usoro ihe nkiri na ihe nkiri na-eme ka HPMC na-arụ ọrụ dị mkpa n'ịmelite arụmọrụ ngwaahịa, imeziwanye ihe owuwu na ihe ndị merenụ. N'ọnọdụ nyocha na ngwa na ngwa na ngwa na ngwa, HPMC ga-agakwa ịkwalite teknụzụ na akụrụngwa na-adọrọ adọrọ ma na-eweta arụmọrụ nke ọma na gburugburu ebe obibi.
