I-Hydroxyethyl Cellulose (HEC) iyi-polymer engeyona i-ionic encibilika emanzini esetshenziswa kabanzi ekwembathweni, kwezimonyo, ezintweni zokuhlanza nezinto zokwakha. Ngenxa yokuqina kwayo okuhle, ukuzinzisa kanye nezakhiwo zefilimu, idinga ukuchithwa emanzini ukuze yenze isisombululo esifanayo lapho sisetshenziswa.
1. Ukulungiselela ukuchithwa
Amathuluzi adingekayo nezinto zokwakha
I-Hydroxyethyl cellulose powder
Amanzi ahlanzekile noma amanzi ahlanganisiwe
Izinto zokusebenza ezinyakazayo (njengama-rod ashukumisayo, ama-stirrers kagesi)
Iziqukathi (njengengilazi, amabhakede epulasitiki)
Izinyathelo zokuzivikela
Sebenzisa amanzi ahlanzekile noma amanzi ahlukanisiwe ukuze ugweme ukungcola okuthinta umphumela wokuhlakazeka.
I-Hydroxyethyl cellulose izwela izinga lokushisa, futhi izinga lokushisa lamanzi lingashintshwa njengoba kudingekile phakathi nenqubo yokuhlakazwa (amanzi abandayo noma indlela yamanzi afudumele).
2. Izindlela ezimbili ezivame ukusetshenziswa zokuchithwa
(1) Indlela yamanzi abandayo
Fafaza impushana kancane: Esitsheni esigcwele amanzi abandayo, kancane kancane ufafaze i-HEC powder emanzini ukuze ugweme ukufaka impushana eningi ngesikhathi esisodwa ukuze ubangele ikhekhe.
Ukugoqa nokuhlakaza: Sebenzisa isivunguvungu ukunyakazisa ngesivinini esiphansi ukuze uhlakaze impushana emanzini ukuze wenze ukumiswa. I-agglomeration ingase yenzeke ngalesi sikhathi, kodwa ungakhathazeki.
Ukuma nokumanzisa: Vumela ukuhlakazeka kume amahora angu-0.5-2 ukuvumela impushana imunce ngokuphelele amanzi futhi ivuvuke.
Qhubeka ugqugquzela: Hlanganisa kuze kube yilapho isixazululo sibonakala ngokuphelele noma singenawo umuzwa we-granular, okuvame ukuthatha imizuzu engu-20-40.
(2) Indlela yamanzi afudumele (indlela yangaphambi kokuhlakazwa kwamanzi ashisayo)
Ukusabalalisa kwangaphambili: Engeza inani elincaneI-HECimpushana ibe ngu-50-60℃ emanzini ashisayo bese ugovuza ngokushesha ukuze uyihlakaze. Qaphela ukugwema i-powder agglomeration.
Ukuhlanjululwa kwamanzi abandayo: Ngemva kokuba impushana isihlakaziwe ekuqaleni, engeza amanzi abandayo ukuze unciphise ekugxiliseni okuhlosiwe futhi ugovuze ngesikhathi esifanayo ukusheshisa ukuchithwa.
Ukupholisa nokuma: Linda ikhambi liphole futhi ume isikhathi eside ukuze uvumele i-HEC ukuthi incibilike ngokuphelele.
3. Izindlela eziyinhloko zokuqeda
Gwema i-agglomeration: Uma ungeza i-HEC, yifafaze kancane futhi uqhubeke ugqugquzela. Uma kutholakala ama-agglomerations, sebenzisa isisefo ukuze uhlakaze impushana.
Ukulawula izinga lokushisa lokuncibilika: Indlela yamanzi abandayo ifanele izixazululo ezidinga ukugcinwa isikhathi eside, futhi indlela yamanzi afudumele inganciphisa isikhathi sokuchithwa.
Isikhathi sokuhlakazwa: Singasetshenziswa uma ukukhanya sekufinyelele ngokugcwele ezingeni elijwayelekile, okuvame ukuthatha imizuzu engu-20 ukuya emahoreni ambalwa, kuye ngokucaciswa nokugxilwa kwe-HEC.
4. Amanothi
Ukugxila kwesixazululo: Ngokuvamile kulawulwa phakathi kuka-0.5% -2%, futhi ukugxila okukhethekile kulungiswa ngokuvumelana nezidingo zangempela.
Isitoreji nokuzinza: Isixazululo se-HEC kufanele sigcinwe esitsheni esivaliwe ukuze kugwenywe ukungcoliswa noma ukuchayeka endaweni yokushisa ephezulu ethinta ukuzinza kwayo.
Ngezinyathelo ezingenhla,i-hydroxyethyl celluloseingancibilika ngokuphumelelayo emanzini ukuze yenze isixazululo esifana nesesicacile, esifanele izimo ezihlukahlukene zohlelo lokusebenza.
