1. Okwu mmalite:
Ihe mkpuchi mkpuchi na-eje ozi dị ka akwa mkpuchi, na-eme ka ịdịte aka na ịma mma nke elu dị iche iche, sitere na mgbidi na ngwá ụlọ ruo na mbadamba ọgwụ.Hydroxypropyl Methylcellulose (HPMC), polymer vasatail ewepụtara na cellulose, na-enye ihe pụrụ iche nke nwere ike imeziwanye ịdịte aka mkpuchi.
2. Ịghọta Hydroxypropyl Methylcellulose (HPMC):
HPMC bụ cellulose ewepụtara site n'ịgbanwe cellulose eke site na etherification.Ọ nwere ọtụtụ njirimara a na-achọsi ike, gụnyere solubility mmiri, ikike imepụta ihe nkiri, na nkwalite nrapanye.Njirimara ndị a na-eme ka HPMC bụrụ ihe mgbakwunye bara uru na nhazi mkpuchi.
3.Uru nke HPMC na mkpuchi:
Nkwado dị mma: HPMC na-eme ka adhesion nke mkpuchi dị iche iche dịkwuo mma, na-akwalite mkpuchi elu dị mma ma na-ebelata ihe ize ndụ nke delamination ma ọ bụ peeling.
Mgbochi mmiri: Ụdị hydrophobic nke HPMC na-enye aka na mmiri na-eguzogide mmiri nke mkpuchi, na-egbochi ntinye mmiri na ichebe ihe ndị dị n'okpuru site na mmebi.
Mwepụta a na-achịkwa: Na mkpuchi ọgwụ, HPMC na-enyere aka ntọhapụ ọgwụ a na-achịkwa, na-ahụ na nnyefe usoro ọgwụgwọ ziri ezi na nsonaazụ ọgwụgwọ ka mma.
Mgbanwe na ịdị ike: Mkpuchi na-agụnye HPMC na-egosipụta mmụba na ike siri ike, na-ebelata ohere nke mgbawa ma ọ bụ chipping, karịsịa na gburugburu ebe nrụgide dị elu.
Enyi na gburugburu ebe obibi: A na-enweta HPMC site na isi mmalite ndị a na-emegharịgharị ma bụrụkwa ihe na-emebi emebi, na-eme ka ọ bụrụ nhọrọ dị mma maka gburugburu ebe obibi maka nhazi mkpuchi.
4.Applications nke HPMC na mkpuchi:
Ihe mkpuchi ihe owuwu: A na-ejikarị HPMC eme ihe n'ime ime na n'èzí iji kwalite adhesion, mgbochi mmiri, na ịdịte aka, na-agbatị ndụ nke ihe osise.
Mkpuchi ọgwụ: Na ụlọ ọrụ ọgwụ, HPMC na-arụ ọrụ dị ka onye na-emepụta ihe nkiri na mkpuchi mbadamba, na-eme ka mwepụta ọgwụ na-achịkwa ma na-emeziwanye ndụ shelf.
Mkpuchi osisi: A na-eji mkpuchi nke HPMC na-emecha na osisi iji chebe mmiri, radieshon UV, na ihe eji arụ ọrụ, na-echekwa iguzosi ike n'ezi ihe nke elu osisi.
Mkpuchi akpaaka: HPMC na-eme ka arụmọrụ nke mkpuchi ụgbọ ala dịkwuo mma site n'inye nkwụsi ike ọkọchị, nchebe corrosion, na ihu igwe, na-eme ka aesthetics elu na-adịte aka.
Mkpuchi mkpuchi: A na-etinye HPMC n'ime mkpuchi nkwakọ ngwaahịa iji nye ihe mgbochi, na-egbochi mmiri mmiri na ikuku gas, si otú a na-agbatị ndụ nchekwa nke ngwongwo ekpokọtara.
5. Ihe ịma aka na echiche:
Ọ bụ ezie na HPMC na-enye ọtụtụ uru, ojiji ya dị irè na mkpuchi na-achọ nhazi nke ọma na njikarịcha usoro.A ga-edozirịrị ihe ịma aka dị ka ndakọrịta na mgbakwunye ndị ọzọ, njikwa viscosity na kinetics imepụta ihe nkiri iji bulie uru nke HPMC ka ọ na-ejigide arụmọrụ mkpuchi na nkwụsi ike.
6. Ọdịnihu na ọnọdụ na ohere:
Ọchịchọ maka mkpuchi eco-eco-friendly na nkwalite ịdịte aka na-aga n'ihu na-eto, nyocha na-anya ụgbọ ala na ihe ọhụrụ n'ọhịa nke mkpuchi dabere na HPMC.Mmepe n'ọdịnihu nwere ike ilekwasị anya na usoro ọhụrụ, usoro nhazi dị elu, na ị nweta akụrụngwa na-adịgide adịgide iji mezuo ihe ndị ụlọ ọrụ chọrọ na ụkpụrụ nhazi.
Hydroxypropyl Methylcellulose (HPMC) na-anọchite anya mgbakwunye na-ekwe nkwa maka ịkwalite ịdịte aka nke mkpuchi n'ofe ngwa dị iche iche.Ngwongwo ya pụrụ iche na-enye aka n'ịkwado mmachi, mgbochi mmiri, mgbanwe na ntọhapụ a na-achịkwa, na-eme ka ọ bụrụ ihe dị mkpa na nhazi mkpuchi nke oge a.Site n'ịkwalite uru nke HPMC na ịkwado ihe ịma aka ndị metụtara, ụlọ ọrụ mkpuchi nwere ike ịmepụta ihe ngwọta ọhụrụ na-ejikọta arụmọrụ, nkwado, na ọrụ gburugburu ebe obibi.
