HydroxyPropyl methylcellse (HPMC) ni polymedi kandi ikoreshwa cyane mu nganda zitandukanye, izwiho imitungo yihariye na porogaramu. Iki kigo ni inkoko ya selile, polymer karemano iboneka mu nkike za selile. Kugira ngo wumve ibigize HydroxyPropylmethylcellCellcese, birakenewe gucengera muburyo na Synthesis yuru rwa silile.
Imiterere ya selile:
Cellulose ni karbohyd carbohyd igizwe numurongo wumurongo wa β-d-glucose zifitanye isano na β-1,4-glycosic. Iyi minyururu ya glucose ifatanije na hydrogen kugirango ikore imiterere yumurongo. Cellulose nigice cyingenzi cyubaka inkuta zamababi, zitanga imbaraga nimbaraga zo gutera selile.
Ibikomoka kuri HydroxyPropyl Methylcellse:
HydroxyPropyl Methylcellse igasimbana na selile ihinduranya simusi na mydroxyPropy na methyl mumatsinda nyamukuru ya selile ya selile. Umusaruro mubisanzwe urimo intambwe zikurikira:
Igisubizo cya Guhuza:
Ubwiza: Gufata selile hamwe nigisubizo cya alkaline na methyl chloride kugirango itangire amatsinda ya methyl (-ch3) mumatsinda ya hydroxyl (-Oh) ya selile.
HydroxyProlation: Methylated TELELOSE Reacts hamwe na popide ya propay kugirango utangire amatsinda ya hydroxyProypoyl (-ch2chohch3) muburyo bwa selile. Iyi nzira izamura amazi yo kwikebagura kandi ihindura imitungo yumubiri ya selile.
Gusukura:
Ubugari bwahinduwe noneho bwera kugirango bukureho reagent zose zidasubirwaho, ibicuruzwa cyangwa umwanda.
Kuma no gusya:
HydroxyPropyl methylcellsellse yumye kandi ubutaka bwiteguye gukoresha muburyo butandukanye.
Ibikoresho bya HydroxyPropyl Methylcellse:
Ibigize HydroxyPropyl Methylcellse birangwa nurwego rwo gusimburwa, bivuga urwego rwitsinda rya hydroxyPropyl na methyl basimbuye amatsinda ya hydroxyl muri parikingi. Ibyiciro bitandukanye bya HPMC bifite impamyabumenyi itandukanye, bigira ingaruka kubibazo byabo, vicosity nibindi bintu.
Imiti yimiti ya hydroxypropyl methylcellse irashobora kugaragazwa nka (c6h7o2 (OH) 3-MN (OHT) (OHX, aho m na n ihagarariye urwego rwo gusimbuza.
UMWIGISHA: Urwego rwa Methylation (Amatsinda ya Methyl kuri Glucose Igice)
N: Urwego rwa HydroxyProupy
X: Umubare wibice bya glucose muri chuline ya selile
Ibiranga na porogaramu:
Gukemurwa: HPMC ni ugushonga amazi, kandi urwego rwo gusimburwa rugira ingaruka kubiranga byonyine. Ikora igisubizo gisobanutse kandi gikomeye mumazi, bigatuma bikwiranye nuburyo butandukanye.
IYI GISPOSITION: IYI GEREZA Z'IQUE CYA HPMC RIT'Iteka Biterwa n'ibintu nk'uburemere bwa molecular n'urwego rwo gusimbuza. Uyu mutungo ningirakamaro kubisabwa nka farumasi bisaba kugenzurwa.
Gushiraho filime: HPMC irashobora gukora firime zoroheje nkigisubizo gikurura, bigatuma ari ingirakamaro mubikota muri farumasi muri farumasi, ibiryo nizindi nganda.
Intebe n'abarimbyi: mu nganda z'ibiryo, HPMC ikoreshwa nk'igituba n'intangarugero mu bicuruzwa bitandukanye, harimo isosi, ibintu bitetse, n'ibicuruzwa biteye ubwoba.
Gusaba imiti: HPMC ikoreshwa cyane mumirire ya farumasi, harimo ibisate, captules, hamwe nibisubizo bya Ophthalmic, bitewe numutekano wagenzuwe na biocomp.
Kubaka no Gukoperating: HPMC ikoreshwa mubikoresho byubwubatsi nka minisiteri, tile yizihiza na plaster. Irakoreshwa kandi nkuwabyimbye kandi ikingamiro mubirangi no guhinga.
Ibicuruzwa byita ku giti cye: Mu kwisiga no kwita ku nganda bwite, HPMC iboneka mu bicuruzwa nka cream, amavuta na shampos, aho bitanga imiterere no guturo.
HydroxyPropyl Methylcellse iboneka by methylation na hydroxy opepy of selile. Nintego nyinshi Polymer ifite uburyo butandukanye. Umutungo wacyo wihariye uhindura agaciro munganda nka faruceti, ibiryo, kubaka no kwitabwaho kugiti cyawe. Kugenzurwa na selile birashobora guhumuririra neza imiterere ya HPMC, bikabikora ibintu byingenzi bikomoka mubuzima bwacu bwa buri munsi.
