Ukulungiselela isisombululo se-methylcellulose kubandakanya amanyathelo amaninzi kunye neengqwalasela, kubandakanywa nokukhetha ibakala elifanelekileyo le-methylcellulose, ukugqiba ugxininiso olufunwayo, kunye nokuqinisekisa ukuchithwa okufanelekileyo.I-Methylcellulose yikhompawundi eguquguqukayo esetyenziswa ngokubanzi kumashishini ahlukeneyo, kubandakanywa amayeza, ukutya, kunye nezithambiso, ngenxa yokuqina kwayo, i-gelling, kunye neempawu zokuzinzisa.
1. Ukukhetha iBanga leMethylcellulose:
I-Methylcellulose ifumaneka kumabakala ahlukeneyo, ngalinye line-viscosity eyahlukeneyo kunye neempawu ze-gelation.Ukukhethwa kwebakala kuxhomekeke kwisicelo esicetywayo kunye neempawu ezifunwayo zemveliso yokugqibela.Amabanga ane-viscosity ephezulu aqhele ukusetyenziswa kwizicelo ezifuna izisombululo ezityebileyo okanye iijeli, ngelixa amabanga asezantsi e-viscosity afanelekile ukwakheka kwamanzi amaninzi.
2. Ukumisela Ugxininiso olufunekayo:
Ukuxinwa kwesisombululo se-methylcellulose kuya kuxhomekeka kwiimfuno ezithile zesicelo sakho.Ugxininiso oluphezulu luya kubangela izisombululo ezityebileyo okanye iigels, ngelixa ugxininiso oluphantsi luya kuba luninzi.Kubalulekile ukumisela ugxininiso olufanelekileyo olusekelwe kusetyenziso olucetywayo, ngokuqwalasela izinto ezifana ne-viscosity, ukuzinza, kunye nokuhambelana nezinye izithako.
3. Izixhobo kunye neMathiriyeli:
Ngaphambi kokuqala inkqubo yokulungiselela, qokelela zonke izixhobo eziyimfuneko kunye nemathiriyeli:
I-methylcellulose powder
Amanzi adibeneyo okanye enye i-solvent efanelekileyo
Isixhobo sokuvuselela (umzekelo, i-magnetic stirrer okanye i-mechanical stirrer)
Isilinda esithweswe isidanga okanye ikomityi yokulinganisa
Iibhekile okanye izitya zokuxuba
Isilinganisi-manzi (ukuba siyafuneka)
imitha ye-pH okanye imigca yesalathisi se-pH (ukuba iyafuneka)
4. Inkqubo yokuLungisa:
Landela la manyathelo ukulungiselela isisombululo se-methylcellulose:
Inyathelo 1: Ukulinganisa umgubo weMethylcellulose
Ukusebenzisa isikali sedijithali, linganisa umlinganiselo ofanelekileyo we-methylcellulose powder ngokuhambelana noxinzelelo olufunayo.Kubalulekile ukulinganisa umgubo ngokuchanekileyo ukufezekisa i-viscosity efunwayo kunye nokuhambelana kwesisombululo sokugqibela.
Inyathelo lesi-2: Yongeza i-Solvent
Beka umlinganiselo olinganisiweyo we-methylcellulose powder kwisitya esicocekileyo, esomileyo.Kancinci ukongeza i-solvent (umzekelo, amanzi adibeneyo) kumgubo ngelixa uvuselela ngokuqhubekayo.Ukongezwa kwe-solvent kufuneka kwenziwe ngokucothayo ukuthintela ukuhlangana kunye nokuqinisekisa ukusasazeka okufanayo kwe-methylcellulose.
Inyathelo lesi-3: Ukudibanisa kunye nokuchithwa
Qhubeka uvuselela umxube de i-methylcellulose powder ihlakazwe ngokupheleleyo kwaye iqale ukunyibilika.Ngokuxhomekeke kwibakala kunye nokugxilwa kwe-methylcellulose esetyenzisiweyo, ukuchithwa okupheleleyo kunokuthatha ixesha.Ukushisa okuphezulu kunokukhawuleza inkqubo yokutshatyalaliswa, kodwa ugweme ukudlula imilinganiselo yokushisa ephakanyisiweyo, njengoko inokuchaphazela iipropati zesisombululo.
Inyathelo lesi-4: Ukulungelelanisa i-pH (ukuba kuyimfuneko)
Kwezinye izicelo, kunokuba yimfuneko ukulungisa i-pH yesisombululo se-methylcellulose ukufezekisa iipropati ezifunwayo okanye ukuphucula ukuzinza.Sebenzisa imitha ye-pH okanye imicu ye-pH yesalathisi ukulinganisa i-pH yesisombululo kwaye uyilungelelanise njengoko kuyimfuneko ngokudibanisa ixabiso elincinci le-asidi okanye isiseko.
Inyathelo lesi-5: Ukuvumela ukuQiniswa kwamanzi
Emva kokuba i-methylcellulose powder ichithe ngokupheleleyo, vumela isisombululo ukuba sikhuphe ixesha elaneleyo.Ixesha le-Hydration lingahluka ngokuxhomekeke kwibakala kunye nokugxininiswa kwe-methylcellulose esetyenzisiweyo.Ngeli xesha, isisombululo sinokugqithiswa ngakumbi okanye i-gelling, ngoko beka iliso kwi-viscosity yayo kwaye ulungelelanise njengoko kuyimfuneko.
Inyathelo lesi-6: I-Homogenization (ukuba kuyimfuneko)
Ukuba isisombululo se-methylcellulose sibonisa ukungaguquguquki okungalinganiyo okanye i-particle aggregation, i-homogenization eyongezelelweyo ingafuneka.Oku kunokufezekiswa ngokuqhubela phambili okanye ukusebenzisa i-homogenizer ukuqinisekisa ukusabalalisa okufanayo kweengqungquthela ze-methylcellulose.
Inyathelo lesi-7: Ukugcinwa kunye nokuphatha
Xa sele ulungisiwe, gcina isisombululo se-methylcellulose kwisingxobo esicocekileyo, esivalwe ngokuqinileyo ukukhusela ungcoliseko kunye nokunyuka kwamanzi.Izikhongozeli ezibhalwe ngokufanelekileyo kufuneka zibonise ukugxininiswa, umhla wokulungiswa, kunye nazo naziphi na iimeko ezifanelekileyo zokugcinwa (umzekelo, ubushushu, ukukhanya kokukhanya).Phatha isisombululo ngononophelo ukuphepha ukuchitheka kunye nokugcina ingqibelelo yaso.
5. Ukusombulula ingxaki:
Ukuba i-methylcellulose powder ayichithi ngokupheleleyo, zama ukwandisa ixesha lokuxuba okanye ukulungelelanisa ukushisa.
Ukudityaniswa okanye ukusasazwa okungalinganiyo kunokukhokelela ekongezeni isinyibilikisi ngokukhawuleza okanye ukungonelanga ukuxubana.Qinisekisa ukongezwa ngokuthe ngcembe kwesinyibilikisi kunye nokuvuselela ngokucokisekileyo ukuphumeza ukusasazwa okufanayo.
Ukungahambelani nezinye izithako okanye ukugqithiswa kwe-pH kunokuchaphazela ukusebenza kwesisombululo se-methylcellulose.Cinga ngokuhlengahlengisa ukwakheka okanye ukusebenzisa ezinye izongezo ukuphumeza iimpawu ezinqwenelekayo.
6. Iingqwalasela zoKhuseleko:
Phatha i-methylcellulose powder ngononophelo ukuze ugweme ukuphefumla okanye ukudibana nolusu kunye namehlo.Nxiba izixhobo ezifanelekileyo zokuzikhusela (umzekelo, iiglavu, iiglasi) xa uphethe umgubo.
Landela iinkqubo ezifanelekileyo zokhuseleko kunye nezikhokelo xa usebenza ngeekhemikhali kunye nezixhobo zaselebhu.
Ukulahla nayiphi na isisombululo se-methylcellulose engasetyenziswanga okanye ephelelwe lixesha ngokwemigaqo yendawo kunye nezikhokelo zokulahlwa kwenkunkuma yeekhemikhali.
ukulungiselela isisombululo se-methylcellulose kubandakanya ukukhetha ibakala elifanelekileyo, ukugqiba ugxininiso olufunwayo, kunye nokulandela inkqubo yesinyathelo-nge-nyathelo yokuchithwa kunye ne-homogenization.Ngokulandela ezi zikhokelo kunye nokuqwalasela izilumkiso zokhuseleko, unokulungisa izisombululo ze-methylcellulose ezihambelana neemfuno zakho zesicelo.
