Izici ezithinta ukugcinwa kwamanzi kwe-cellulose ether

Umthamo wokugcinwa kwamanzi we-cellulose izithathekisa, njenge-hydroxypropyllylylylylylyl methyl celtule Kunezici eziningana zingathinta izakhiwo zokugcina amanzi ze-cellulose afesther:

1. Isakhiwo samakhemikhali: Ukwakheka kwamakhemikhali ze-cellulose 'TETERS kuthonya amandla abo okugcina amanzi. Izici ezifana nezinga lokufaka esikhundleni (DS), isisindo se-molecular, kanye nohlobo lwamaqembu ether (isib.
2. I-degree yokufaka esikhundleni (DS): Ama-degree aphezulu wokufaka esikhundleni ngokuvamile aholela ekukhulisweni komthamo wokugcina amanzi. Lokhu kungenxa yokuthi imiphumela ephakeme ye-DS ngamaqembu amaningi we-hydrophilic ether e-cellulose backbone, ethuthukisa ubudlelwano be-polymer emanzini.
3. Isisindo samangqamuzana: Izithambiso zeCellulose ezinesisindo esiphakeme samangqamuzana zibonisa izakhiwo ezingcono zokugcina amanzi. Amaketanga amakhulu e-polymer angafaka ngempumelelo enkulu, akha inethiwekhi edonsa ama-molecule wamanzi ngaphakathi kohlelo isikhathi eside.
4. Ubungako bezinhlayiyana kanye nokusatshalaliswa: ezintweni zokwakha, ezinjengezingodo kanye nokwenza izimali, usayizi wezinhlayiyana nokusatshalaliswa kwezithambisi ze-cellulose kungathinta ukuhluka kwabo kanye nokufana kwe-matrix. Ukuhlakazeka okufanele kuqinisekisa ukuxhumana okuphezulu ngamanzi nezinye izinto, ukuthuthukisa ukugcinwa kwamanzi.
5. Izinga lokushisa kanye nomswakama: izimo zemvelo, ezinjengokushisa kanye nomswakama, zingathonya ukusebenza kwezithambisi zamanzi ze-cellulose afebur. Amazinga okushisa aphezulu namazinga omswakama ophansi angasheshisa ukuhwamuka kwamanzi, anciphise umthamo wokugcina wamanzi wohlelo.
6. Inqubo yokuxuba: Inqubo yokuxuba esetshenziswe ngesikhathi sokulungiswa kokwakhiwa okuqukethe izithambisi ze-cellulose kungathinta izakhiwo zazo zokugcina amanzi. Ukuhlakazeka okufanele kanye ne-hydration yezinhlayiya ze-polymer kubalulekile ukuze wandise ukusebenza kwawo ekugcinweni kwamanzi.
7. Ukuvumelana kwamakhemikhali: Abathambisi beCellulose kufanele bahambisane nezinye izakhi ezikhona ekwakhiweni, njengokusimende, okuhlanganisiwe, kanye nama-admixtures. Ukungalingani noma ukusebenzisana nezinye izengezo kungathinta inqubo ye-hydration futhi ekugcineni umthelela wokugcinwa kwamanzi.
8. Izimo zelapha: Izimo ze-Pring, kufaka phakathi isikhathi sokuvuka kanye nokuvuka kwelapha, kungathonya i-hydration kanye nentuthuko yamandla ezintweni ezisetshenziswayo zikasimende. Ukwelashwa okufanele kuqinisekisa ukugcinwa komswakama okwanele, ukukhuthaza ukusabela kwe-hydration kanye nokwenza ngcono ukusebenza okuphelele.
9. Izinga lokungezelela: Inani le-cellulose ether elingezwe ekwakhekeni futhi lithinta ukugcinwa kwamanzi. Amazinga we-decouge afanele kufanele anqunywe ngokususelwa kwizidingo ezithile zohlelo lokusebenza ukuze afinyelele izakhiwo zokugcina amanzi ozifunayo ngaphandle komthelela omubi kwezinye izici zokusebenza.

Ngokucabanga ngalezi zinto, amakhemikhali angakhulisa izakhiwo zokugcina amanzi ezithwala izithako ezinhlelweni ezahlukahlukene, okuholela ekusebenzeni okuthuthukile nokuqina kwemikhiqizo yokugcina.
