I-Eletherafication zokwenziwa umgomo we-hydroxypropylylylylylylylylylylylylylyll methyl cellulose (HPMC)

I-Hydroxypropyl Methylcellulose ((HPMC), i-Cellulose eluhlaza, ingahlaziywa ukotini noma i-soni upulp, ngaleyo ndlela ichitheke indawo yayo ye-collulose ye-cellulose ye-cellulose ye-cellulose ye-cellulose ye-cellulose ye-cellulose ye-cellulose ye-cellulose ye-cellulose ye-cellulose ye-cellulose ye-cellulose ye-cellulose ye-cellulose ye-cellulose ye-cellulose ye-cellulose ye-cellulose ye-cellulose ye-cellulose ye-cellulose ye-cellulose ye-cellulose ye-cellulose elisakhiweni kwe-crystallity kanye nekhono lokuphendula kwamakhemikhali ye-realent realivent ukuze Amaqembu amathathu e-hydroxyl eqenjini le-glucose ring ye-cellulose macromolecule.

I-Hydroxypropylm methylcellulose (HPMC) isetshenziswa njenge-substrate engavuthiwe yokukhiqiza uwoyela, ongabona ukusetshenziswa koshukela okuphelele, athuthukise inani lokusetshenziswa kwezinto ezingavuthiwe emhluzisweni we-Fermentation, futhi anciphise izindleko zokwelashwa kwamanzi amdaka. Le hydroxypropyll methyllellose Izici ze-methylcellose zilungele ukusetshenziswa kwe-batch, fed-batch nezinqubo eziqhubekayo zokuvutshelwa, ukugwema uchungechunge lwezinkinga ezinjengokulawula ukwakheka kwezinga eliphakathi nendawo; Kuyasiza futhi ekuqondisweni kwenqubo yokuvutshelwa. Njengoba ukusebenza kwe-hydroxypropyllylylyl (HPMC) kuyafana nezinye izithambisa amanzi, kungasetshenziswa ku-latex Paint kanye ne-emulsifier depin ukumelana, ukuqina kanye nokunamathela, futhi kuthuthukiswe i-acyness, futhi ukuhambisana ne-acid ne-alkali, kanye nokuhambisana imibala yensimbi.

I-Hydroxypropyl Methylcellulose (HPMC) inomphumela omuhle njengoMkhulu we-White Polyvinyl Acetate Paint. Izinga lokufaka esikhundleni se-surlulose ether liyanda, futhi ukumelana nokuguguleka kwamagciwane nakho kuyathuthukiswa.

Yize i-ethesherication synthesis yesimiso se-hydroxypropyllllylyllylylylyllll (HPMC) asiyinkimbinkimbi, idinga ukubalwa, izinto ezivuthiwe, ezibonakalayo zihleliwe, kanye ne-alkalized. Imvelo ngayinye yokuthezeka, ukululama kwe-solvent, i-centrifugation, ukugeza nokugeza kuhilela inani elikhulu lobuchwepheshe obukhulu nolwazi olucebile.

Ngezinhlobo ezahlukene zemikhiqizo, imvelo ngayinye inezimo zakamuva zokulawula, njengokushisa, isikhathi, ingcindezi nokulawulwa kokugeleza kwezinto ezibonakalayo. Imishini yokusiza nokulawula izinsimbi zokulawula ziyiziqinisekiso ezinhle zekhwalithi yomkhiqizo ezinzile nezinhlelo zokukhiqiza ezithembekile.
