I-seluplose ebhaka, njengemethylcelsulose (MC),hydroxypropyl methylcelculose (hpmc), kwayeI-Carboxymethyl Selelose (CMC), zisetyenziswa ngokubanzi kwizicelo ezahlukeneyo kubandakanya amayeza, uzokwakha, kunye namashishini okutya. Enye yepropathi ebalulekileyo ye-seluplose ebhaka kwazo ukugcina amanzi, ebaluleke kakhulu ekusebenzeni kwazo kwezi zicelo. Ukugcinwa kwamanzi kuqinisekisa ukuba izinto ezihlala ziyifom enqwenelekayo kunye nemisebenzi ngokufanelekileyo, nokuba kwisisombululo esiqinileyo, ijeli, okanye njengenxalenye yematrix.
1.Injongo
Injongo yovavanyo lokugcina amanzi kukulinganisa inani lamanzi isisele i-seluplose sinokubamba phantsi kweemeko ezithile. Le ndawo ibalulekile kuba ichaphazela ukusebenza, uzinzo, kunye nokusebenza kweemveliso eziseSelete Ether ezikwimeko ezahlukeneyo.
2.Umgaqo
Ukugcinwa kwamanzi kugqitywa ngokulinganisa ubunzima bamanzi agciniweyo yi-Telupese Ether xa iphantsi kovavanyo oluthe kratya. Ngokwesiqhelo, umxube we-ether ese seluplose ulungiswa ngamanzi, kwaye ke isixa samanzi asimahla esinyinyithiweyo okanye oxhonywe kumxube phantsi koxinzelelo. Ukuphakama kokugcinwa kwamanzi, kokukhona kuya kubakho amandla e-ete i-selsulose ukubamba umswakama.
3.Izixhobo kunye nezixhobo

I-thermostat okanye i-incubator-Ukugcina ubushushu bovavanyo (ngokuqhelekileyo kubushushu begumbi, malunga ne-20-25 ° C)
4.Inkqubo
Ukulungiswa kwesampula:
Ukulinganisa isixa esaziwayo se-ether i-ether powder (i-2 yeegram) ngokuchanekileyo kwibhalansi.
Hlanganisa i-Sether i-seluplose i-ether powder ngenani elithile lamanzi anemilinganiselo (umzekelo, i-100 ml) ukwenza isilayidi okanye ipasika. Hambisa umxube ngokupheleleyo ukuqinisekisa ukusasazeka kunye nokuntywila.
Vumela umxube ukuze i-hydrate kangangemizuzu engama-30 ukuqinisekisa ukudumba ngokupheleleyo kwe-seluplose.
Ukuseta kwezixhobo zokugcina amanzi:
Lungiselela izixhobo zokugcina amanzi ngokubeka iphepha lokucoca kwiyunithi yelitha okanye i-funnel.
Galela i-Ether Ither i-Setery Slight iphepha lokucoca kwaye uqiniseke ukuba lisasazeke ngokulinganayo.
Umgangatho wokugcina wokugcina:
Faka isicelo soxinzelelo kwisampulu nokuba kusetyenziswa umatshini ogcweleyo wasentwasahlobo. Isixa soxinzelelo kufuneka sibekwe emgangathweni kuzo zonke iimvavanyo.
Vumela inkqubo ikhutshelwe imizuzu emi-5 ukuya kweli-10, apho amanzi agqithisileyo aya kwahlulwa kwisilayi.
Qokelela amanzi atyhidiweyo kwisilinda esiphumelele.
Ukubalwa kokugcina amanzi:
Emva kokuba inkqubo yokurhola igqityiwe, inobunzima amanzi aqokelelweyo ukufumanisa inani lamanzi alahlekileyo.
Bala ukugcinwa kwamanzi ngokukhupha isixa samanzi asimahla kwinani lokuqala lamanzi asetyenzisiweyo kumxube wesampulu.
Ukuphindaphinda:
Yenza uvavanyo ngokutshata kwimodeli nganye ye-Selese ye-ether ukuqinisekisa iziphumo ezichanekileyo nezibuyisiweyo. Ixabiso lokugcina amanzi eliphakathi lisetyenziselwa ingxelo.
5.Ingcaciso yedatha
Iziphumo zovavanyo lokugcina amanzi luhlala lubonakaliswa njengepesenti yamanzi agcinwe yisampulu ye-Selese. Ifomula yokubala ukugcinwa kwamanzi yile:
Le fomula inceda ekuvavanyeni ubungakanani bomthamo weselfowuni
6.Vavanya umahluko
Olunye umahluko wovavanyo olusisiseko lokugcina amanzi lubandakanya:
Ukugcinwa kwamanzi axhomekeke kwixesha:Kwezinye iimeko, ukugcinwa kwamanzi kunokulinganiswa ngexesha lamaxesha ahlukeneyo (umz.
Ukugcina amaqondo obushushuIimvavanyo eziqhutywa kubushushu obahlukeneyo zinokubonisa ukuba ubushushu buchaphazela njani ukugcinwa kwamanzi, ngakumbi kwizinto ezibuthathaka.
7.Izinto ezichaphazela ukugcinwa kwamanzi
Izinto ezininzi zinokuba nefuthe ekugcinweni kwamanzi aselfowuni:
I-Viskosity:I-seluplose esuka e-vilecofity ephezulu idla ngokugcina amanzi amaninzi.
Ubunzima bemolekyuli:I-selupulose ye-molecular yemolekyuli ephakamileyo idla ngokuba nomgangatho ongcono wamanzi ngenxa yesakhiwo sabo semolekyuli.
Inqanaba lokufaka endaweni:Uhlengahlengiso lwekhemikhali lweeselwase
Ugxininiso lwe-seluplose ether kumxube:Ukugxininiswa okuphezulu kweselselese ether ngokubanzi kukhokelela ekugcinweni kwamanzi.
8.Itheyibhile yesampulu: umzekelo iziphumo
| Uhlobo lwesampulu | Amanzi okuqala (ml) | Ukuqokelelwa kwamanzi (ml) | Ukugcinwa kwamanzi (%) |
| Methylcelsulose (MC) | I-100 | 70 | Iipesenti ezingama-30 |
| Hydroxypropyl methylcelculose (hpmc) | I-100 | 65 | Iipesenti ezingama-35 |
| I-Carboxymethyl Selelose (CMC) | I-100 | 55 | Iipesenti ezingama-45 |
| I-viscofity ephezulu ye-MC | I-100 | 60 | I-40% |
Kule mizekelo, iingalo zokugcina amanzi zibonisa ukuba i-carboxymethyl selsulose (CMC) inesona sigqibo samanzi sinendawo ephezulu yamanzi, ngelixa i-methylcelsulose (MC) ineyona ndlela iphantsi.
Uvavanyo lokugcina amanzi kwi-seluplose tal luphawu oluyimfuneko lokulawula ukulinganisa amandla ezinto ezinokubamba amanzi. Iziphumo ziyanceda ekumiseleni ukufaneleka kwe-ethessese i-ether yezicelo ezithile, njengokwekhetha apho ulawulo lokufuma lubalulekile khona. Ngokupenda okusemgangathweni wenkqubo yovavanyo, abavelisi banokuqinisekisa ukusebenza okungaguqukiyo kweemveliso zabo zeselfowuni kwaye banike idatha eluncedo kuphuhliso lwemveliso.
IXESHA LOKUQALA: FEB-19 ukuya ku-1525
