1. Ihe ndị bụ isi nke HPMC
HPMC (Hydroxypropyl Methylcellulose) bụ nonionic cellulose ether nke a na-ejikarị eme ihe na ụlọ ọrụ dị iche iche, karịsịa n'ọhịa nke ihe owuwu na ụlọ ọrụ mmepụta ihe. HPMC nwere ezigbo mmiri solubility, ndim, nrapado, njide mmiri na ihe na-emepụta ihe nkiri, nke na-eme ka ọ bụrụ ihe dị mkpa na nhazi ihe nrapado.
2. Onye na-ejigide mmiri na mmiri
Otu n'ime isi ojiji HPMC na-eji adhesives bụ dị ka onye na-agbapụta mmiri na ihe na-ejigide mmiri. N'ihi mmiri solubility ya dị mma, HPMC nwere ike ịgbaze ngwa ngwa na mmiri wee mepụta ngwọta viscosity dị elu. Ihe onwunwe a na-enyere HPMC aka ịbawanye viscosity nke nrapado nke ọma ma melite mkpuchi na ịrụ ọrụ nke nrapado n'oge a na-ewu ya. Tụkwasị na nke ahụ, njide mmiri nke HPMC na-enyere ya aka igbochi mmiri ịpụpụ ngwa ngwa n'oge a na-ewu ya, si otú ahụ gbasaa oge oghere nke nrapado na-eme ka njikọ ahụ dị.
3. Adhesiveness na Film Formation
Adhesiveness nke HPMC bụ ọrụ ọzọ dị mkpa na adhesives. HPMC nwere ike welie ike bonding nke nrapado, karịsịa akpụ a ike bonding oyi akwa na interface na kọntaktị na mkpụrụ. Tụkwasị na nke ahụ, ihe nkiri na-emepụta ihe nkiri nke HPMC na-enyere ya aka ịmepụta otu ihe nkiri na nnukwu ihe mgbe ihe ntanye ahụ nwụsịrị, si otú ahụ na-eme ka ọ dịkwuo ogologo na nkwụsi ike nke nrapado. A na-eji ihe ndị a eme ihe n'ọtụtụ ebe na ngwaahịa dị ka ihe nrapado akwụkwọ ahụaja, ihe nrapado tile, na nrapado osisi.
4. Mmelite nke ịrụ ọrụ ihe owuwu
Na adhesives ihe owuwu, HPMC ọ bụghị naanị na-eme ka njirimara anụ ahụ nke ngwaahịa ahụ dịkwuo mma, kamakwa ọ na-eme ka arụ ọrụ nke usoro ihe owuwu ahụ dịkwuo mma. Dịka ọmụmaatụ, na nrapado tile na ngwa agha, HPMC nwere ike inye mmanu mmanu na ihe mgbochi, na-ebelata ihe mkpofu mgbe a na-ewu ụlọ. Tụkwasị na nke ahụ, iji HPMC nwekwara ike imeziwanye ihe ndị na-egbochi nkwụsị nke nrapado, na-ahụ na mmetụta pasta mgbe e wuchara ya dị nro ma mara mma.
5. Enyi na gburugburu ebe obibi na nchekwa
Dị ka ihe sitere n'okike cellulose, HPMC nwere ọmarịcha biocompatibility na biodegradability. Nke a na-eme ka ọ bụrụ ihe nrapado zuru oke na ọha mmadụ nke oge a nwere ihe nchebe gburugburu ebe obibi na-esiwanye ike. Tụnyere ụfọdụ ndị na-eji kemịkalụ ọdịnala na ndị na-ejigide mmiri, HPMC enweghị ihe ndị na-egbu egbu na ihe ndị na-emerụ ahụ, ọ dị mma iji ya, yana enwechaghị mmetụta na gburugburu ebe obibi. Ya mere, a na-eji HPMC eme ihe na nrapado na-ewu ụlọ, ngwá ụlọ, nkwakọ ngwaahịa na ụlọ ọrụ ndị ọzọ, na-ezute nchebe gburugburu ebe obibi ọgbara ọhụrụ na ahụike chọrọ.
6. Ngwa kpọmkwem nke HPMC na ụdị adhesives dị iche iche
Adhesives ihe owuwu: A na-eji HPMC eme ihe n'ọtụtụ ebe na nrapado ihe owuwu dị ka ihe nrapado tile, nrapado akwụkwọ ahụaja, na ngwa agha ụlọ. Njide mmiri ya dị mma na ihe na-eme ka ọ dịkwuo mma nwere ike igbochi mmiri na-efunahụ na mkpụrụ ahụ, na-eme ka ike njikọ na ịdị mma ụlọ.
Ngwunye osisi: N'ime ụlọ ọrụ osisi, HPMC, dị ka ihe mgbakwunye, nwere ike ịkwalite ike njikọ na ịdịte aka nke glues osisi ma belata nsogbu mgbagwoju anya na nsogbu nsogbu nke gluu na-eme n'oge ihicha.
Akwụkwọ ngwaahịa na nkwakọ ngwaahịa adhesives: A na-ejikarị HPMC eme ihe dị ka onye na-ekpo ọkụ na mmiri na-ejide mmiri na adhesives na ngwaahịa akwụkwọ na ụlọ ọrụ nkwakọ ngwaahịa iji meziwanye viscosity na fluidity nke adhesives na hụ na njikọ siri ike nke akwụkwọ na nkwakọ ngwaahịa.
Nri na ọgwụ adhesives: A na-ejikwa HPMC na nri na ụlọ ọrụ ọgwụ dịka akụkụ nke ụfọdụ nrapado, dị ka adhesives maka mbadamba ọgwụ na adhesives na nkwakọ ngwaahịa nri, n'ihi nchekwa ya na adịghị egbu egbu.
7. ọdịnihu mmepe atụmanya
Site na mmepe nke teknụzụ nrapado na-aga n'ihu, ihe ndị chọrọ ịrụ ọrụ maka ihe na-abawanye elu. Dịka mgbakwunye multifunctional, HPMC nwere atụmanya ngwa sara mbara. N'ọdịnihu, na-ewusi nchebe gburugburu ebe obibi na mmepe mmepe na-adịgide adịgide, HPMC ga-ejikarị mee ihe na nrapado green. Tụkwasị na nke a, site n'ịgbanwe usoro ihe omimi nke HPMC, enwere ike ịmepụta ọtụtụ ihe mmepụta HPMC nwere ihe pụrụ iche iji gboo mkpa dị iche iche nke ụlọ ọrụ dị iche iche maka adhesives.
Ngwa sara mbara nke HPMC na adhesives bụ n'ihi ọmarịcha anụ ahụ na kemịkal ya. Ọ nwere ike ịrụ ọtụtụ ọrụ dị ka ịgbatị, njigide mmiri, imepụta ihe nkiri na njikọta na nrapado dị iche iche. Site na ọganihu nke nkà na ụzụ na mgbanwe nke ahịa ahịa, ngwa ngwa nke HPMC ga-anọgide na-amụba, na-enye nkwado siri ike maka mmepe nke ụlọ ọrụ ntanye.
