IHydroxypropyl methylcellulose (HPMC) yi-ether eyi-soluble nonionic cellulose ebalulekileyo enyibilikayo emanzini kunye nokutyeba okulungileyo, i-gelling, i-bonding, ifilimu yokwenza ifilimu, i-lubricating, i-emulsifying kunye nokumisa imisebenzi, ngoko isetyenziswa ngokubanzi kwizinto zokwakha, amayeza, ukutya, izithambiso kunye nezinye iinkalo. .
Indlela yokujiya ye-hydroxypropyl methylcellulose
Isiphumo esityebileyo se-HPMC sivela ikakhulu kwisakhiwo sayo semolekyuli. Ikhonkco lemolekyuli ye-HPMC iqulethe i-hydroxyl kunye namaqela e-methyl, anokwenza iibhondi ze-hydrogen kunye neemolekyuli zamanzi, ngaloo ndlela zithintele intshukumo phakathi kweemolekyuli zamanzi kunye nokwandisa i-viscosity yesisombululo. Xa i-HPMC ichithwe emanzini, ikhonkco layo leemolekyuli lityhila emanzini kwaye lisebenzisana neamolekyuli zamanzi ukwenza isakhiwo sothungelwano, ngaloo ndlela kwandisa i-viscosity yesisombululo. Isakhono esityebileyo se-HPMC sikwachatshazelwa yimiba efana nenqanaba layo lokuthatha indawo, ubunzima bemolekyuli kunye noxinzelelo.
Ukusetyenziswa kwe-hydroxypropyl methylcellulose kwizinto zokwakha
Kwimathiriyeli yokwakha, i-HPMC isetyenziswa ikakhulu kwiimveliso ezifana nodaka lwesamente, imathiriyeli esekwe kwigypsum kunye nezaleko njengento ejiyileyo kunye nokugcina amanzi. Umphumo wayo wokuqina unokuphucula ukusebenza kokwakhiwa kwezinto kunye nokuphucula ukusebenza kwayo okuchasayo, oko kwenza inkqubo yokwakha ibe lula. Ngokomzekelo, kudaka lwesamente, ukongezwa kwe-HPMC kunokunyusa i-viscosity yodaka kwaye kuthintele udaka ukuba lungabikho xa lwakhiwe kwindawo ethe nkqo. Kwakhona kunokuphucula ukugcinwa kwamanzi odaka kwaye kuthintele udaka ukuba lome ngokukhawuleza, ngaloo ndlela luphucula amandla kunye nokuqina kodaka.
Ukusetyenziswa kweHydroxypropyl Methylcellulose kwiNdawo yoShishino
Kwintsimi yamachiza, i-HPMC isetyenziswa ngokubanzi kwiipilisi, ii-capsules, iigels, amalungiselelo e-ophthalmic kunye namanye amayeza njenge-thickener, ifilimu yangaphambili kunye ne-adhesive. Isiphumo sayo esihle sokuqina sinokuphucula iimpawu ze-rheological zamayeza kunye nokuphucula ukuzinza kunye ne-bioavailability yamayeza. Ngokomzekelo, kumalungiselelo e-ophthalmic, i-HPMC ingasetyenziswa njenge-lubricant kunye ne-thickener, kwaye umphumo wayo omhle wokuqina unokwandisa ixesha lokuhlala kwechiza kwindawo ye-ocular, ngaloo ndlela iphucula ukusebenza kwechiza.
Ukusetyenziswa kweHydroxypropyl Methylcellulose kuKutya
Kushishino lokutya, i-HPMC isoloko isetyenziswa ekutyeni okufana neemveliso zobisi, iijeli, iziselo kunye neemveliso ezibhakiweyo njenge-thickener, emulsifier and stabilizer. Umphumo wayo wokuqina unokuphucula incasa kunye nokuthungwa kokutya, kunye nokwandisa i-viscosity kunye nokuzinza kokutya. Ngokomzekelo, kwiimveliso zobisi, i-HPMC inokunyusa i-viscosity yemveliso kwaye ithintele i-whey precipitation, ngaloo ndlela iphucula incasa kunye nokuzinza kwemveliso.
Ukusetyenziswa kweHydroxypropyl Methylcellulose kwiCosmetics
Kwinkalo yezithambiso, i-HPMC isetyenziswa kakhulu kwiimveliso ezifana nezithambiso, iikhrimu, iishampu kunye nezipholileyo njenge-thickener, emulsifier and stabilizer. Umphumo wayo wokuqina unokuphucula ukuthungwa kunye nokuzinza kwezithambiso, kunye nokuphucula umphumo wokusetyenziswa kunye namava omthengi wemveliso. Ngokomzekelo, kwi-lotions kunye ne-creams, ukongezwa kwe-HPMC kunokunyusa i-viscosity yemveliso, okwenza kube lula ukuyifaka kunye nokufunxa, ngelixa kuphuculwe umphumo wokunyusa imveliso.
IHydroxypropyl Methylcellulose isetyenziswe ngokubanzi kwizinto zokwakha, amayeza, ukutya kunye nezithambiso ngenxa yeempawu zayo ezigqwesileyo zokujiya. Indlela yayo yokuqina ikakhulu kukunyusa i-viscosity yesisombululo ngokwenza iibhondi ze-hydrogen kunye neemolekyuli zamanzi, zithintele ukuhamba kweeathomu zamanzi. Imimandla eyahlukeneyo ineemfuno ezahlukeneyo zesicelo kwi-HPMC, kodwa umsebenzi wayo ongundoqo kukuphucula i-viscosity kunye nokuzinza kwemveliso. Ngokuqhubela phambili kwesayensi kunye nobuchwepheshe kunye nophuhliso oluqhubekayo lweteknoloji yesicelo, amathuba okusetyenziswa kwe-HPMC aya kuba banzi.
