Ungayenza kanjani isixazululo se-hec?

I-HEC (HydroxYethyl celtuleose) iyinhlangano evamile yokuqina kanye ne-emulsifier stabilizer, esetshenziswa kabanzi lapho kulungiswa izixazululo, ama-emulsions, ama-gels, njll. Isetshenziswa izimonyo, izimbotshana, izinto zokwakha, amakhamishini.

1. Ukulungiselela
Ngaphambi kokuthi uqale ulungiselele isixazululo se-hec, qiniseka ukuthi ulungiselele izinto ezilandelayo namathuluzi:
I-HEC powder (ukucaciswa kwe-HEC okutholakalayo okuvame ukuba namabanga okubona ahlukile, futhi umkhiqizo ofanele kufanele akhethwe ngokwesicelo esithile)
I-solvent (imvamisa amanzi ahlanzekile, amanzi e-deionized noma amanye ama-sol afanelekile asetshenziswa)
Idivaysi evuthayo (i-magnetic stirrer noma i-mehendi starrer)
Idivaysi yokulawula lokushisa (njengokugeza kwamanzi)
Isitsha (ingilazi noma esitsheni esishukumisayo sepulasitiki esinevolumu eyanele)
Ukunemba isilinganiso se-elekthronikhi (sokuthola isisindo esinembile se-hell ye-hec)

2. Izinyathelo eziyisisekelo zokulungiswa kwesisombululo
2.1 Khetha i-solvent
I-HEC ine-soubity enhle emanzini, kodwa ukuze ivikele i-agglomeration noma ukusakazeka okungalingani ngesikhathi sokuchithwa, umyalo wokungezelelwa kanye nesivinini sokuvusa kufanele kulawulwa ngokucophelela. Amanzi e-deionized avame ukusetshenziswa njenge-solvent. Uma udinga ukulungiselela isixazululo se-Organic Solvent System Hec, udinga ukukhetha uhlelo olufanele lwe-solvent (njengohlelo oluxubile lwe-ethanol namanzi).

2.2 Ukushisa Amanzi
Izinga lokuchithwa kwe-HEC lihlobene nokushisa kwamanzi. Ukuze usheshise ukuqedwa kwe-hec, amanzi afudumele (cishe ama-50 ° C) kuvame ukusetshenziswa, kepha akuphezulu kakhulu ukugwema ukusebenza kwe-HEC. Faka amanzi e-deionized esitsheni, qala ukufudumeza, bese uvumelanisa izinga lokushisa elifanele (40-50 ° C).

2.3 avuse ngokuqinile
Ngenkathi amanzi eshisa, qala ukushukumisa. Idivayisi evuthayo ingaba yisitayela sobukazi noma isivuseleli semishini. Isivinini esishukumisayo esilinganiselayo kufanele sigcinwe ukuze sigweme ukugeleza kwamanzi ngokweqile ngenkathi kuqinisekisa ukuxubana okufanayo.

2.4 Ngeza kancane i-hell hew
Lapho amanzi efudunyezwa ku-40-50 ° C, qala ngokungezelela kancane i-hell ye-hec. Ukuze ugweme i-agglomeration ye-powder, kufanele ifakwe kancane ngenkathi ivusa. Izindlela ezilandelayo zingasetshenziswa ukwenza ngcono umphumela wokuhlakazeka:

Ngeza kuma-batches: ungathululi konke ngasikhathi sinye, ungangeza ngamanani amancane amahlandla amaningi, bese ulinda kuze kube yilapho i-powder ihlakazeka ngokungeziwe ngemuva kokungezwa ngakunye ngaphambi kokungeza ngokuzayo.
Isihlungo: fafaza i-hec powder ngokusebenzisa ngesihlungo emanzini ukusiza ukunciphisa i-agglomeration ye-powder.
Lungisa ijubane lokuvusa: Lapho ufafaza i-powder, lungisa ijubane elishukumisayo ngokufanele ukuze ulondoloze amandla athile we-shear, alungele ukwanda nokuhlakazeka okufanayo kwama-molecule e-cellulose.

2.5 Qhubeka uvuse kuze kuncibilike ngokuphelele
Ukuchithwa kwe-HEC kuyinqubo ehamba kancane kancane. Njengoba i-powder ihlakazeka futhi ichithwe, ikhambi lizoqina kancane kancane. Ukuqinisekisa ukuthi i-HEC iyachithwa ngokuphelele, qhubeka uvuselelwa amahora angaba ngu-1-2, futhi isikhathi esithile sincike ekuboneni kwesixazululo nenani le-HEC elalisetshenzisiwe. Uma izigaxa zivela kwikhambi noma isixazululo sichithwa ngokungalingani, isikhathi esivuselelayo singanwetshwa ngokufanelekile noma izinga lokushisa lamanzi lingakhuphulwa libe ngaphezulu kwe-50 ° C.

2.6 Ukupholisa
Lapho i-HEC ichithwa ngokuphelele, yeka ukufudumeza bese uqhubeka uvusetha, bese uvumela isixazululo siphole kancane ekushiseni kwegumbi. Ngesikhathi senqubo yokupholisa, ukubonakala kwesixazululo kungaqhubeka ukukhuphuka kuze kufike isimo esizinzile.

3. Lungisa ukugcwala kwesixazululo
Ukuhlushwa kwesixazululo se-hec kuvame ukulungiswa ngokwesicelo esithile. Uhla lokuhlushwa kwezixazululo olujwayelekile lweHec lungu-0.5% ~ 5%, futhi inani elithile linqunywa ngokuya ngomphumela odingekayo wokuqina. Okulandelayo ifomula yokubala inani elidingekayo le

I-HEC:

Inani le-hec (g) = ivolumu yesixazululo (ml) ×

Isibonelo, uma udinga ukulungiselela i-1000ML yesisombululo se-1% we-Hec, udinga i-10g ye-hell ye-hec.

Uma i-viscosity yekhambi liphezulu kakhulu noma liphansi kakhulu ngemuva kokulungiselela, ungalilungisa ngalezi zindlela ezilandelayo:

Ukuqina: Uma i-viscosity akwanele, engeza inani elincane le-hew powder. Qikelela ukuthi uyingeze kuma-batches ukugwema ukuhlanganisa.

I-Dilution: Uma i-viscosity yekhambi liphezulu kakhulu, engeza amanzi abonakalayo ukuze alifakele ngendlela efanele.

4. Isixazululo Filtration
Ukuqinisekisa ukufana kanye nobumsulwa besixazululo sokugcina, kungahlungwa ngephepha lesihlungo noma lokuhlunga. I-Filtration ingasusa izinhlayiya ezingezinhle noma ukungcola okungenzeka, ikakhulukazi ezicelo ezifunwayo (ezinjengemithi noma izimonyo).

5. Ukulondolozwa nokugcinwa
Isixazululo se-hec esilungiselelwe kufanele sivalwe ukuvikela ukuguquguquka nokungcola. Kunconywa ukuyigcina endaweni epholile neyomile kude nokukhanya kwelanga okuqondile. Uma ikhambi ligcinwa isikhathi eside, ukungcoliswa kwe-microbial kungenzeka. Kunconywa ukwengeza inani elifanele lezinto zokugcina (njenge-phenoxyethanol, methylisothiazolinone, njll.) Njengoba kudingeka.

6. Ukuqapha
Gwema i-AGGGGOMOR: I-HEC Powder ilula kakhulu ukugibela emanzini, ikakhulukazi lapho ungeza ngokushesha okukhulu noma ukushukumisa akwanele. Kunconywa ukusebenzisa indlela yokungeza kuma-batches futhi ulungise isivinini esivusa amadlingozi ukuze uqinisekise ukuthi i-powder ihlakazeka ngokulinganayo.
Ukulinganiswa kwe-Viscosity: Uma kunesidingo, ukubukeka kwesixazululo kungalinganiswa kusetshenziswa imishini efana ne-veliccometer ejikelezayo ukuqinisekisa ukuthi ihlangabezana nezidingo zohlelo lokusebenza.
Ukulondolozwa: Uma isixazululo se-HEC sigcinwa isikhathi eside, ukungezelela kwezivikelo kubaluleke kakhulu ukuvikela ukukhula kwama-microorganisms kwikhambi futhi kubangele ukuthi ikhambi liwohloke.

Isihluthulelo sokwenza isixazululo se-Hec ukulawula izinga lokushisa le-solvent, isivinini esivusa amadlingozi kanye nendlela yokungeza ye-hemputer ye-hell ukuqinisekisa ukuthi i-HEC ingahlakazeka ngokulinganayo futhi ichithwe ngokugcwele. I-Agglomeration kufanele ivinjelwe ngesikhathi sokuchithwa, futhi ikhwalithi yesisombululo ingathuthukiswa ngokuhlunga uma kunesidingo. Ngemuva kokufunda kahle la masu, ungalungiselela ngempumelelo izixazululo ze-HEC ezihlangabezana nezidingo zakho futhi uzisebenzise kwimikhiqizo ehlukahlukene yezimboni neyosuku nosuku.
