Ukulungisa isisombululo se-methylcellulose kuhilela izinyathelo ezimbalwa nokucatshangelwa, okuhlanganisa ukukhetha izinga elifanele le-methylcellulose, ukunquma ukugxila okufunayo, nokuqinisekisa ukuchithwa okufanele.I-Methylcellulose iyinhlanganisela eguquguqukayo esetshenziswa kabanzi ezimbonini ezahlukahlukene, kufaka phakathi ezemithi, ukudla, nezimonyo, ngenxa yokuqina kwayo, i-gelling, kanye nezakhiwo zokuzinzisa.
1. Ukukhetha Ibanga le-Methylcellulose:
I-Methylcellulose itholakala emabangeni ahlukahlukene, ngalinye line-viscosity ehlukene kanye nezakhiwo ze-gelation.Ukukhethwa kwebanga kuncike ekusetshenzisweni okuhlosiwe kanye nezici ezifiswayo zomkhiqizo wokugcina.Amabanga ane-viscosity ephakeme ngokuvamile asetshenziselwa izinhlelo zokusebenza ezidinga izixazululo eziwugqinsi noma amajeli, kuyilapho amamaki e-viscosity aphansi afanele ukwakheka koketshezi okwengeziwe.
2. Ukunquma Ukugxila Okufiselekayo:
Ukugxila kwesixazululo se-methylcellulose kuzoncika ezidingweni ezithile zohlelo lwakho lokusebenza.Ukugxila okuphezulu kuzoholela ekuxazululeni noma kumajeli aminyene, kuyilapho ukugxila okuphansi kuzoba uketshezi oluningi.Kubalulekile ukunquma ukugxiliswa okuphelele ngokusekelwe ekusetshenzisweni okuhlosiwe, kucatshangelwa izici ezifana ne-viscosity, ukuqina, nokuhambisana nezinye izithako.
3. Izinsiza Nezisetshenziswa:
Ngaphambi kokuqala inqubo yokulungiselela, qoqa zonke izinto ezidingekayo nezinto zokwakha:
I-methylcellulose powder
Amanzi acwengekile noma enye i-solvent efanelekile
Izinto zokusebenza ezinyakazayo (isb., i-stirrer kazibuthe noma i-mechanical stirrer)
Isilinda esithweswe iziqu noma inkomishi yokulinganisa
Amabhontshisi noma iziqukathi zokuxuba
I-thermometer (uma idingeka)
Imitha ye-pH noma imichilo yenkomba ye-pH (uma idingeka)
4. Inqubo yokulungiselela:
Landela lezi zinyathelo ukuze ulungise isisombululo se-methylcellulose:
Isinyathelo 1: Ukukala I-Methylcellulose Powder
Ukusebenzisa isikali sedijithali, linganisa inani elifanele le-methylcellulose powder ngokusho kokuhlushwa okufunayo.Kubalulekile ukukala i-powder ngokunembile ukuze kuzuzwe i-viscosity oyifunayo kanye nokuvumelana kwesixazululo sokugcina.
Isinyathelo sesi-2: Engeza i-Solvent
Beka inani elilinganisiwe le-methylcellulose powder esitsheni esihlanzekile, esomile.Kancane kancane yengeza isincibilikisi (isb., amanzi acwengekile) kumpushana kuyilapho ugqugquzela njalo.Ukwengezwa kwe-solvent kufanele kwenziwe kancane ukuvimbela ukunqwabelana nokuqinisekisa ukuhlakazeka okufanayo kwe-methylcellulose.
Isinyathelo sesi-3: Hlanganisa futhi Uhlakaze
Qhubeka ugqugquzela ingxube kuze kube yilapho i-methylcellulose powder isihlakazeke ngokugcwele futhi iqala ukuncibilika.Ngokuya ngebanga nokugxila kwe-methylcellulose esetshenzisiwe, ukuqedwa okuphelele kungathatha isikhathi.Amazinga okushisa aphakeme angasheshisa inqubo yokuqedwa, kodwa gwema ukweqa imingcele yokushisa enconywayo, njengoba kungase kuthinte izakhiwo zesixazululo.
Isinyathelo sesi-4: Ukulungisa i-pH (uma kunesidingo)
Kwezinye izinhlelo zokusebenza, kungase kudingeke ukulungisa i-pH yesisombululo se-methylcellulose ukuze kuzuzwe izakhiwo ezifiselekayo noma ukuthuthukisa ukuzinza.Sebenzisa imitha ye-pH noma imichilo yenkomba ye-pH ukukala i-pH yesisombululo bese uyilungisa njengoba kudingeka ngokungeza amanani amancane e-asidi noma isisekelo.
Isinyathelo sesi-5: Ukuvumela ukugeleza kwamanzi
Ngemuva kokuthi i-methylcellulose powder isihlakazeke ngokugcwele, vumela isisombululo ukuthi siphuze isikhathi esanele.Isikhathi sokukhipha amanzi singahluka kuye ngebanga nokugxila kwe-methylcellulose esetshenzisiwe.Ngalesi sikhathi, isixazululo singase siqhubeke nokuqina noma i-gelling, ngakho-ke qapha i-viscosity yayo futhi ulungise njengoba kudingeka.
Isinyathelo sesi-6: I-Homogenization (uma kunesidingo)
Uma isisombululo se-methylcellulose sibonisa ukungaguquguquki okungalingani noma ukuhlanganisa izinhlayiyana, kungase kudingeke i-homogenization eyengeziwe.Lokhu kungafezwa ngokuqhubezela phambili noma ngokusebenzisa i-homogenizer ukuqinisekisa ukuhlakazeka okufanayo kwezinhlayiya ze-methylcellulose.
Isinyathelo sesi-7: Isitoreji Nokuphatha
Uma usulungisiwe, gcina isixazululo se-methylcellulose esitsheni esihlanzekile, esivalwe ngokuqinile ukuze uvimbele ukungcoliswa nokuhwamuka.Iziqukathi ezilebulwe kahle kufanele zibonise ukugxila, usuku lokulungiswa, nanoma yiziphi izimo ezifanele zokugcinwa (isb., izinga lokushisa, ukukhanya okukhanyayo).Phatha isixazululo ngokucophelela ukuze ugweme ukuchitheka futhi ugcine ubuqotho baso.
5. Ukuxazulula inkinga:
Uma i-methylcellulose powder ingaqedi ngokuphelele, zama ukwandisa isikhathi sokuxuba noma ukulungisa izinga lokushisa.
Ukunqwabelana noma ukuhlakazeka okungalingani kungase kubangele ukwengeza isincibilikisi ngokushesha kakhulu noma ukuxuba okunganele.Qinisekisa ukwengezwa kancane kancane kwe-solvent kanye nokugqugquzela okuphelele ukuze uzuze ukuhlakazeka okufanayo.
Ukungahambisani nezinye izithako noma ukweqisa kwe-pH kungase kuthinte ukusebenza kwesisombululo se-methylcellulose.Cabangela ukulungisa ukwakheka noma ukusebenzisa ezinye izithasiselo ukuze uzuze izici ozifisayo.
6. Ukucatshangelwa kokuphepha:
Phatha i-methylcellulose powder ngokucophelela ukuze ugweme ukuhogela noma ukuthintana nesikhumba namehlo.Gqoka izinto zokuzivikela ezifanele (isb., amagilavu, izibuko) lapho ubamba impushana.
Landela izinqubo zokuphepha ezifanele kanye neziqondiso lapho usebenza ngamakhemikhali nempahla yaselabhorethri.
Lahla noma yisiphi isisombululo se-methylcellulose esingasetshenzisiwe noma esiphelelwe yisikhathi ngokwemithetho yendawo kanye nemihlahlandlela yokulahlwa kukadoti wamakhemikhali.
ukulungiselela isisombululo se-methylcellulose kuhilela ukukhetha ibanga elifanele, ukunquma ukugxila okufunayo, nokulandela inqubo yesinyathelo ngesinyathelo yokuqedwa kanye ne-homogenization.Ngokulandela le mihlahlandlela futhi ucabangele izinyathelo zokuphepha, ungalungisa izixazululo ze-methylcellulose ezihambisana nezidingo zakho zohlelo lokusebenza.
