IHydroxYethyl Cellulose (HEC) i-polymer encibilikayo yamanzi esetshenziswa kakhulu njengomuntu omkhulu, i-emulsifier, stabilizer, njll.
IHydroxYethyl Cellulose Disolution Izinyathelo
Lungiselela izinto zokwakha nemishini:
Hydroxyethyl cellulose powder
Solvent (imvamisa amanzi)
Idivaysi evuthayo (efana ne-mehendi starrer)
Ukulinganisa Amathuluzi (Isilinda Ukulinganisa, Ibhalansi, njll.)
Okokuphatha
Ukushisa i-solvent:
Ukusheshisa inqubo yokuqothula, i-solvent ingashisa ngendlela efanele, kepha ngokuvamile akufanele idlule ku-50 ° C ukugwema ukonakala okungekho emthethweni. Izinga lokushisa lamanzi phakathi kuka-30 ° C no-50 ° C alungile.
Ngena kancane kancane u-HEC Powder:
Shayela kancane u-hec powder emanzini afudumele. Ukugwema ukuhlangana, kwengeze ngesihlungo noma kufafaze kancane. Qiniseka ukuthi i-hele ye-HEC ihlakazeka ngokulinganayo ngesikhathi senqubo evuthayo.
Qhubeka nokuvusa:
Ngesikhathi senqubo evuthayo, qhubeka ungeze kancane i-hewc ye-hec ukuze uqinisekise ukuthi i-powder ihlakazeka ngokulinganayo emanzini. Ijubane elishukumisayo akufanele lishelele kakhulu ukuvikela ama-bubble kanye ne-agglomeration. Isivinini esiphakathi nendawo esisheshayo sivame ukunconywa.
Ukuyeka Ukuchithwa: Ngemuva kokuhlakazwa okuphelele, kuvame ukudingekile ukuma isikhathi (imvamisa amahora amaningi noma isikhathi eside) ukuvumela i-HEC ukuthi ichithe ngokuphelele futhi yakha isixazululo esifanayo. Isikhathi sokuma sincike esimeni samangqamuzana se-HEC kanye nokuhlushwa kwesixazululo.
Ukulungisa Ukubonakala: Uma i-viscosity idinga ukulungiswa, inani le-HEC linganda ngokufanele noma lehlile. Ngaphezu kwalokho, ingashintshwa ngokungeza ama-electrolyte, eshintsha inani le-PH, njll.
Izindlela zokuqothula ekuqothulweni
Gwema i-AGGGOMELION Isihlungo noma enye idivaysi ehlakazayo ingasetshenziselwa ukusiza ukusakazeka ngokulinganayo.
Ukulawulwa kokulawula: Ukushisa kwe-solvent akufanele kube phezulu kakhulu, ngaphandle kwalokho kungadala ukonakaliswa okushisayo kwe-HEC futhi kuthinte ukusebenza kwesixazululo. Imvamisa kufanelekile ukuyilawula phakathi kuka-30 ° C no-50 ° C.
Vimbela umoya ekungeneni: Gwema ukushukumisa ngokushesha okukhulu ukuvikela umoya ukuthi ungene kwikhambi ukuze wakhe ama-bubble. Ama-Bubble azothinta ukufana nokubonakala kwesixazululo.
Khetha imishini yokuvuselela efanelekile: Khetha imishini yokuvuselela efanele ngokuya ngokubonakala kwesixazululo. Ngezixazululo eziphansi ze-viscosity, izitha ezejwayelekile zingasetshenziswa; Ngezixazululo eziphezulu kwe-viscosity, kungadingeka isivutuka esinamandla.
Ukugcinwa Nokulondolozwa:
Isixazululo esincibilikisiwe se-Hec kufanele sigcinwe esitsheni esivalwe ukuvimba umswakama noma ukungcoliswa. Lapho igcinwe isikhathi eside, gwema ukukhanya kwelanga okuqondile nendawo yokushisa ephezulu ukuze uqinisekise ukuqina kwesixazululo.
Izinkinga ezijwayelekile nezixazululo
Ukuchithwa okungalingani:
Uma kwenzeka kokuchithwa okungafanele, kungahle kube ngoba i-powder ifafazwe ngokushesha noma ivuswe ngokungafanele. Isixazululo ukuthuthukisa ukufana kokuvuselelwa, kwandise isikhathi sokuvuselela, noma ukulungisa ijubane lokungezwa kwempuphu ngenkathi kuvusa.
Isizukulwane se-Bubble:
Uma inani elikhulu lama-bubble livela kwikhambi, ama-bubble angancishiswa ngokunciphisa ijubane elishukumisayo noma aliyeke lime isikhathi eside. Ama-bubble asevele akha, umenzeli we-degassing angasetshenziswa noma ukwelashwa kwe-ultrasonic kungasetshenziselwa ukuwasusa.
I-Viscosity yesisombululo iphakeme kakhulu noma iphansi kakhulu:
Lapho isixazululo se-visosision esingahlangabezani nezidingo, zingalawulwa ngokulungisa inani le-HEC. Ngaphezu kwalokho, ukuguqula inani le-PH kanye namandla e-Ionic wesisombululo kungathinta nokubonakala.
Ungawuhlakaza ngempumelelo i-hydroxyethyl cellulose futhi uthole isisombululo esilinganayo nesizinzile. Ukwenza kahle izinyathelo ezisebenzayo zokusebenza kanye nezinyathelo zokuphepha kungandisa umphumela we-hydroxyethyl cellulose kuzicelo ezahlukahlukene.
