I-Hydroxyyethyl cellulose (HEC) Ingabe i-polymer engenawo amanzi e-nonic asetshenziswa kabanzi ekuhlotsheni, izimonyo, okokuhlanza kanye nezinto zokwakha. Ngenxa yokuqina kwayo okuhle, okuqinisile kanye nezakhiwo ezenziwe ngefilimu, kudinga ukuchithwa emanzini ukuze kwakhiwe isixazululo esifanayo lapho sisetshenziswa.
1. Ukulungiswa kokuchithwa
Amathuluzi adingekayo nezinto zokwakha
Hydroxyethyl cellulose powder
Amanzi ahlanzekile noma amanzi e-deionized
Imishini evusa amadlingozi (enjengezinduku ezishukumisayo, abagqugquzeli bakagesi)
Iziqukathi (njengengilazi, amabhakede epulasitiki)
Izinyathelo zokuzivikela
Sebenzisa amanzi ahlanzekile noma amanzi ahlanzekile ukugwema ukungcola okuthinta umphumela wokuchitheka.
IHydroxYethyl Cellulose iyazwela izinga lokushisa, kanti izinga lokushisa lamanzi lingashintshwa njengoba kudingeka ngesikhathi sokuchithwa (amanzi abandayo noma indlela efudumele yamanzi).
2. Izindlela ezimbili ezivame ukusetshenziswa
(1) indlela ebandayo yamanzi
Shintsha kancane i-powder: esitsheni esigcwele amanzi abandayo, kancane futhi ngokufafaza i-heck powder emanzini ukugwema ukungeza i-powder eningi ngasikhathi sinye ukuze ubangele ukubhomba.
Okushukumisayo nokusabalalisa: Sebenzisa isivusi ukuvusa ngejubane eliphansi ukuhlakaza i-powder emanzini ukuze kwakhiwe ukumiswa. I-Agglomeration ingavela ngalesi sikhathi, kepha ungakhathazeki.
Ukuma nokumanzisa
Qhubeka uvuse: Vuselela kuze kube yilapho isixazululo sisobala ngokuphelele noma singenawo umuzwa we-granular, okuvame ukuthatha imizuzu engama-2040.
(2) Indlela Efudumele Yamanzi (Indlela Eshisayo Yamanzi Pre-Dispersion)
Ukusakazwa kwangaphambili: Faka inani elincane leI-HECi-powder to 50-60 ℃ Amanzi ashisayo ashisayo bese uvusa masinyane ukuyisakaze. Qikelela ukugwema i-agglomeration ye-powder.
I-Dlulion Ebandayo Yomanzi: Ngemuva kokuthi i-powder ekuqaleni ihlakazeke, engeza amanzi abandayo ukuze unciphise kokugxila okuhlosiwe bese uvusa ngasikhathi sinye ukusheshisa ukuchithwa.
Ukupholisa nokuma: Lindela isisombululo ukuze upholile futhi ume isikhathi eside ukuvumela i-HEC ukuthi ichithe ngokuphelele.
3. Amasu Okuqothula Okubalulekile
Gwema i-Agglomeralion: Lapho ungeza i-HEC, fafaza kancane kancane futhi uqhubeke uvuselelwa. Uma kutholakala ama-agglomerations, sebenzisa isihlungo sokuhlakaza i-powder.
Ukulawulwa kwezinga lokushisa: Indlela yamanzi ebandayo ilungele izixazululo ezidinga ukugcinwa isikhathi eside, futhi indlela efudumele yamanzi inganciphisa isikhathi sokuchitheka.
Isikhathi sokuchithwa: Ingasetshenziswa lapho ukucaca kufinyeleleka ngokuphelele ku-standard, okuvame ukuthatha imizuzu engama-20 kuya emahoreni ambalwa, kuya ngokuchazwa kwe-HEC.
4. Amanothi
Ukuhlushwa kwesixazululo: Ngokuvamile kulawulwa phakathi kuka-0.5% -2%, futhi okuhlushwa okuthize kulungiswa ngokuya ngezidingo zangempela.
Isitoreji nokuqina: Isixazululo se-HEC kufanele sigcinwe esitsheni esivalwe ukugwema ukungcoliswa noma ukuvezwa ezindaweni eziphakeme zokushisa ezithinta ukuqina kwalo.
Ngezinyathelo ezingenhla,IHydroxYethyl CelluloseIngancishiswa ngempumelelo emanzini ukuze wakhe isixazululo esifanayo nesibonakalayo, esilungele izimo ezahlukahlukene zohlelo lokusebenza.
