Impahla ebaluleke kakhulu ye-cellulose ether ukugcinwa kwamanzi ezintweni zokwakha. Ngaphandle kokungezwa kwe-cellulose ether, ungqimba omncane wodaka olusha omile ngokushesha kangangokuba usimende ungakwazi ukunqwabelanisa ngendlela ejwayelekile futhi udaka alunakuqina futhi uzuze ukubumbana okuhle. Ngasikhathi sinye, ukungezwa kwe-cellulose ether kwenza udaka abe nepulasitiki enhle nokuvumelana nezimo, futhi athuthukise amandla okubopha ngodaka. Ake sixoxe ngomthelela ekusetshenzisweni kodaka oluxutshwe nodaka olulodwa kusuka ekusebenzeni komkhiqizo we-cellulose ether.
1. Ubumsulwa be-cellulose ether
Ubumsulwa be-cellulose ether buthinta i-solubility yalo. Isibonelo, ukwehlisa ubumsulwa be-ether ye-cellulose, ngokushesha kuyancibilika emanzini kanye nokwenza ngcono ukusebenza kokugcinwa kwamanzi. Ngakho-ke, ubumsulwa be-cellulose ether kufanele bufakwe njengenye yezindawo zayo zokuphenya. Ngokuvamile, okusalayo kwe-subsion ye-cellulose eTher Finess kudlula u-0.212mm akufanele kudlule u-8.0%.
2. Ukomisa Isilinganiso Sokunciphisa Isisindo
Izinga lokulahleka kwesisindo elomile lisho amaphesenti esisindo sezinto ezilahlekile kunqwaba yesampula yasekuqaleni lapho kumiswa khona amazinga okushisa athile. Ikhwalithi ethile ye-cellulose ether, izinga lokunciphisa isisindo liphezulu kakhulu, elizonciphisa okuqukethwe kwezithako ezisebenzayo eCellulose Ether, lithinte umphumela wohlelo lokusebenza lwamabhizinisi aphansi, futhi andise izindleko zokuthenga. Imvamisa, ukulahlekelwa kwesisindo emgodini we-cellulose ether akuyona ngaphezulu kuka-6.0%.
3. I-Sulfate Ash okuqukethwe kwe-cellulose ether
Ikhwalithi ethile ye-cellulose ether, okuqukethwe kwe-Ash kuphezulu kakhulu, okuzokwehlisa okuqukethwe kwezithako ezisebenzayo ku-cellulose ether futhi kuthinte umphumela wohlelo lokusebenza lwamabhizinisi aphansi. Okuqukethwe kwe-ash sulfate ye-cellulose ether kuyindlela ebalulekile yokusebenza kwayo. Kuhlanganiswe nesimo sokukhiqizwa esikhona samanje sabakhiqizi be-cellulose ether be-cellulose ekhona, imvamisa okuqukethwe kwe-ASH, i-HPMC, i-hemc akufanele idlule ama-2,5%, kanye nokuqukethwe komlotha we-HEC Cellulose ETER akufanele kudlule i-10.0%.
4. Ukuvunywa kwe-cellulose ether
Ukugcinwa kwamanzi kanye nomphumela wokuqina we-cellulose ether ikakhulukazi kuncike ekubonakaleni kanye nomthamo we-cellulose ether ngokwako kungezwe ku-slurry kasimende.
I-5 Ivelu ye-PH ye-Cellulose Ether
I-viscosity ye-cellulose ether imikhiqizo izokwehla kancane ngemuva kokugcinwa emazingeni okushisa aphezulu noma isikhathi eside, ikakhulukazi imikhiqizo ephezulu, ngakho-ke kuyadingeka ukukhawulela i-PH. Ngokuvamile, kungakuhle ukulawula ububanzi be-PH be-Cellulose Ether kuya ku-5-9.
6. Ukukhanya okukhanyayo kwe-cellulose ether
Ukudluliselwa kokukhanya kwe-cellulose ether kuthinta ngqo umphumela wohlelo lokusebenza ezintweni zokwakha. Izici eziphambili ezithinta ukudluliselwa kokukhanya kwe-cellulose ether yile: (1) ikhwalithi yezinto zokusetshenziswa; (2) Umphumela we-alkalization; (3) Isilinganiso senqubo; (4) Isilinganiso solvent; (5) umphumela wokungathathi hlangothi.
Ngokomphumela wokusetshenziswa, ukudluliselwa okukhanyayo kwe-cellulose ether akufanele kube ngaphansi kwama-80%.
7. Izinga lokushisa le-gel le-cellulose ether
I-Celsulose Ether isetshenziswa ikakhulukazi njenge-viscosifier, i-ejenti yepulasitiki kanye ne-ejenti yokugcina amanzi emikhiqizweni kasimende, ngakho-ke ukubonwa kwendlela yokuhlola i-gel kuyizindlela ezibalulekile zokubonisa ikhwalithi yekhwalithi ye-cellulose ether. Ukushisa kwe-gel kusetshenziselwa ukuthola uhlobo lwe-cellulose ether, oluhlobene nezinga lokufaka esikhundleni se-cellulose ether. Ngaphezu kwalokho, usawoti nokungcola kungathinta futhi izinga lokushisa le-gel. Lapho amazinga okushisa esixazululo akhuphuka, i-cellulose polymer ilahlekelwa kancane kancane amanzi, futhi ukubonwa kwesixazululo kuyancipha. Lapho iphuzu le-gel lifinyelelwa, i-polymer ihlukunyezwa ngokuphelele futhi yakha ijeli. Ngakho-ke, emikhiqizweni kasimende, izinga lokushisa livame ukulawulwa ngezansi kokushisa kwe-gel lokushisa kokuqala. Ngaphansi kwalesi simo, okwehlise izinga lokushisa, ukukhuphuka okubonakalayo, kanye nokusobala okusobala komphumela wokuqina nokugcinwa kwamanzi.
