Ama-cellulose ether asetshenziswa kakhulu emikhiqizweni kasimende ngenxa yezakhiwo zawo ezihlukile kanye nekhono lokuthuthukisa izici ezihlukahlukene zokusebenza.Nokho, ukuze kuqinisekiswe imiphumela emihle, kubalulekile ukulawula ngempumelelo ukusebenza kwe-cellulose ether emikhiqizweni kasimende.Leli phepha lihlola amasu abalulekile nezindlela zokufinyelela ukulawula okunembile kwezakhiwo ze-cellulose ether, ukudweba imininingwane ezincwadini ezihlobene nocwaningo.
Ukuqonda Iqhaza Le-Cellulose Ether Emikhiqizweni Kasimende:
Ama-cellulose ethers, afana ne-methyl cellulose (MC), i-hydroxyethyl cellulose (HEC), i-hydroxypropyl methylcellulose (HPMC), namanye, adlala indima ebalulekile emikhiqizweni kasimende.Asebenza njengama-ejenti okugcina amanzi, ama-rheological modifiers, izithuthukisi zokunamathela, futhi athuthukise ukusebenza, ukuqina, nezinye izici ezibalulekile.Ukuqonda izindima ezithile kanye nezindlela ze-cellulose ether ezinhlelweni zikasimende kubalulekile ekulawuleni ukusebenza ngempumelelo.
Ukukhethwa kwezinhlobo ezifanele ze-cellulose ether:
Ukukhetha okulungile kohlobo lwe-cellulose ether kubalulekile ekuzuzeni izakhiwo ezifiselekayo emikhiqizweni kasimende.Uhlobo ngalunye lunikeza izici nemisebenzi eyingqayizivele.Ngokwesibonelo, i-MC yaziwa ngokugcina amanzi namandla ayo okuqina, kuyilapho i-HEC inikeza ukulawula okuphakeme kwe-rheological.I-HPMC ihlanganisa izinzuzo eziningi, okuhlanganisa ukunamathela okuthuthukisiwe, ukusebenza kahle, nokugcinwa kwamanzi.Hlola ngokucophelela izidingo ezithile zomkhiqizo wakho usimende bese ukhetha uhlobo lwe-cellulose ether oluqondana kangcono nalezo zidingo.
Ukulawula Umthamo kanye Nosayizi Wezinhlayiyana:
Ukulawula umthamo kanye nosayizi wezinhlayiyana ze-cellulose ether kubalulekile ukuze kuzuzwe izakhiwo ezifiselekayo emikhiqizweni kasimende..Imithamo ephezulu ingase iholele ekwandeni kokugcinwa kwamanzi kanye ne-viscosity, kuyilapho imithamo ephansi ingase ibeke engcupheni izici ezifiselekayo.Usayizi wezinhlayiyana futhi udlala indima ekuhlakazeni nasekusebenzeni kukonke.Umthamo olungile kanye nosayizi wezinhlayiyana kunganqunywa izivivinyo zokuhlola futhi ngokucabangela izidingo ezithile zohlelo lokusebenza.
Umthelela wokwakheka kukasimende nezixube:
Ukwakheka kukasimende kanye nokuba khona kwezinye izingxube kungase kuthinte izakhiwo ze-cellulose ether. kwezinye izixube ezifana nama-superplasticizer noma ama-air-entrainers angasebenzisana nama-cellulose ether futhi athinte ukusebenza kwawo.
Ukulawula Ikhwalithi Nokuhlola:
Ukusebenzisa izinyathelo eziqinile zokulawula ikhwalithi kanye nokwenza ukuhlolwa okuvamile kubalulekile ukuze kuqinisekiswe ukusebenza okungaguquki kwe-cellulose ether emikhiqizweni kasimende..Ukulawulwa kwekhwalithi kufanele kuhlanganise nokuhlolwa kwemingcele ebalulekile efana ne-viscosity, ukugcinwa kwamanzi, isikhathi sokusetha, ukunamathela, kanye nezakhiwo zemishini..Okuvamile. ukuhlola nokuqapha la mapharamitha kukho konke ukukhiqiza kuzosiza ukukhomba noma yikuphi ukuchezuka futhi kuvumele ukulungiswa okufika ngesikhathi ukuze kugcinwe ukusebenza okufunayo.
Ukusebenzisana Nabahlinzeki kanye Nokwesekwa Kobuchwepheshe:
Ukusebenzelana nabahlinzeki be-cellulose ether kanye nokufuna ukusekelwa kwezobuchwepheshe kunganikeza ukuqonda okubalulekile nosizo ekulawuleni ngempumelelo ukusebenza kwabo emikhiqizweni kasimende. imihlahlandlela yohlelo lokusebenza, nosizo lokuhlanganisa i-cellulose ether ukuze kuhlangatshezwane nezidingo ezithile.
Ukulawula ngempumelelo ukusebenza kwama-cellulose ethers emikhiqizweni kasimende kuwumsebenzi onezici eziningi odinga ukuqonda okuphelele kwendima yawo, ukukhethwa kwezinhlobo ezifanele, ukulawulwa komthamo okunembile, ukucatshangelwa kokwakheka kukasimende kanye nengxubevange, ukulawulwa kwekhwalithi okuqinile, nokusebenzisana nabahlinzeki. .Ngokusebenzisa lawa masu namasu, abakhiqizi bangaqinisekisa ukusebenza okungaguquguquki nokuthuthukisiwe kwama-cellulose ethers, okuphumela ekuthuthukisweni kwekhwalithi yomkhiqizo kasimende, ukuqina okuthuthukisiwe kanye nokwaneliseka kwamakhasimende kukonke.
