Kuthonya izici ze-cellulose ether ku-can moder

I-Cellulose Lethers idlala indima enkulu ekuthonyeni izakhiwo zodaka lukasimende, okuthinta ukusebenziseka kwayo, ukunamathela, ukugcinwa kwamanzi kanye namandla omshini. Kunezici eziningana ezingathonya ukusebenza kwezithako ze-cellulose ku-celter data:

1. Ukwakheka kwamakhemikhali: Ukwakheka kwamakhemikhali ze-cellulose afer, kufaka phakathi izinga lokufaka esikhundleni (DS) kanye nohlobo lwamaqembu asebenzayo (isib., Ethyl, i-hydroxypropp), kunomthelela omkhulu ekuziphatheni kosimende. I-DS ephakeme kanye nezinhlobo ezithile zamaqembu asebenzayo angathuthukisa ukugcinwa kwamanzi, ukunamathela, kanye nezindawo zokuqina.
2. Ubungako bezinhlayiyana kanye nokusatshalaliswa: ubukhulu bezinhlayiyana nokusabalalisa kwe-cellulose afers kungathinta ukungafani kwabo nokuxhumana nezinhlayiya zomoya. Izinhlayiya ezinhle ngokusabalalisa okufanayo zivame ukusabalalisa ngempumelelo enkulu ku-matrix kangumaphakathi, okuholela ekuqhubekeni kokugcinwa kwamanzi okuthuthukile nokusebenza.
3. Umthamo: umthamo we-cellulose izithathekisa ngokonamba wodaka ngokuqondile uthinta ukusebenza kwawo ngqo. Amazinga we-DoSAp umthamo anqunywe ngokususelwa ezintweni ezifana nokusebenza okufisayo, izidingo zokugcinwa kwamanzi, namandla emishini. Umthamo owedlulele kungaholela ekunciphiseni ngokweqile noma ukubuyiselwa emuva kokusetha isikhathi.
4. Inqubo yokuxuba: Inqubo yokuxuba, kufaka phakathi isikhathi sokuxuba, ijubane lokuxuba, nokuhleleka kokungezwa kwezithako, kungathonya ukuhlakazwa kanye ne-hydration ye-cellulose afertar. Ukuxuba okufanele kuqinisekisa ukusatshalaliswa okufanayo kwezithambisi ze-cellulose kulo lonke udaka matrix, kuthuthukisa ukusebenza kwazo ekwenzeni ngcono ukusebenziseka kanye nokunamathela.
5. Ukwakheka kwesimende: Uhlobo nokwakheka kukasimende okusetshenziswe ekwakhiweni kodaka kungathinta ukuhambisana kanye nokusebenza kwe-cellulose afes. Izinhlobo ezahlukene zikasimende (isib. I-Portland cement, usimende oxutshwe usimende) zingabonisa ukusebenzisana okuhlukahlukene nge-cellulose kanye nezindawo ezifana nokusetha isikhathi, ukuthuthukiswa kwamandla, nokuqina.
6. Izakhiwo ezihlanganisiwe: Izici ze-aggregates (isib., Ubukhulu bezinhlayiyana, ukwakheka, ukuthungwa komhlaba) kungathonya ukusebenza kwezithambisi ze-cellulose e-wortar. Ama-aggregates anezindawo ezinolaka noma amajamo angajwayelekile anganikeza ukuxhumeka okungcono kwemishini nge-cellulose afesther, ukuthuthukisa ukunamathela kanye nokuhlangana kodaka.
7. Izimo zezemvelo: Izimo zezemvelo ezifana lokushisa, umswakama, kanye nezimo zokwelapha zingathinta i-hydration kanye nokusebenza kwe-cellulose afers ku-cunmer datar. Izinga lokushisa ngokweqile noma umswakama lingaguqula isikhathi sokusetha, ukusebenziseka kanye nezindawo zemishini zodaka oluqukethe izithambiso ze-cellulose.
8. Ukungezelelwa kwezinye izengezo: ukuba khona kwezinye izengezo, ezinjenge-superplastifizer, ama-acents angenisa umoya, noma asethe ama-accelerators, angaxhumana nabasebenza ngokuthambekela kodaka. Ukuhlolwa kokuvumelana kufanele kwenziwe ukuze kuhlolwe imiphumela yokuhlangana noma imiphumela yokuphikisanayo yokuhlanganisa izithambiso ze-cellulose nezinye izithasiselo.

Ukuqonda izici ezithonyelayo ze-cellulose Tather ku-Cement Jature kubalulekile ukwenza kahle ukwakheka kodaka nasekuzuzeni izakhiwo ezifiselekayo njengokusebenza okuthuthukile, ukugcinwa kwamanzi kanye namandla emishini. Ukwenza ukuhlola okucophelela nokulingwa kungasiza ekuboneni imikhiqizo efaneleke kakhulu ye-cellulose ether kanye namazinga we-dosage wezicelo ezithile zodaka.
