Esakhiweni, i-cellulose ether idlala indima yokugcina amanzi, ukuqina, ukubambezeleka kwamandla kasimende, kanye nokwenza ngcono ukusebenza komsebenzi wokwakha.Umthamo omuhle wokugcina amanzi wenza ukugeleza kukasimende kuphelele, kungathuthukisa i-viscosity emanzi yodaka olumanzi, kukhuphule amandla okubopha odaka, futhi kulungise isikhathi.Ukwengeza i-cellulose ether kudaka lokufafaza lomshini kungathuthukisa ukusebenza kokufuthwa noma ukumpompa namandla esakhiwo sodaka.I-Cellulose isetshenziswa kabanzi njengesithako esibalulekile odakeni osulungile.Uma sithatha umkhakha wezinto zokwakha njengesibonelo, i-cellulose ether inezindawo ezinhle kakhulu ezifana nokujiya, ukugcinwa kwamanzi, nokuncipha.Ngakho-ke, i-ether yebanga lezinto zokwakha isetshenziswa kabanzi ukuthuthukisa ukukhiqizwa kodaka oluxubekile (kuhlanganise nodaka oluxubekile olumanzi nodaka oluxutshwe okomile), i-PVC resin, njll. , upende we-latex, i-putty, njll., kufaka phakathi ukusebenza imikhiqizo yokwakha.
I-Cellulose ingabambezela inqubo ye-hydration kasimende.I-cellulose ether inika udaka olunezinto ezihlukahlukene ezizuzisayo, futhi inciphisa ukushisa kwangaphambi kwesikhathi kwe-hydration kasimende futhi ibambezele inqubo ye-hydration ashukumisayo kasimende.Lokhu akulungile ukusetshenziswa kodaka ezindaweni ezibandayo.Lo mphumela wokuvinjelwa ubangelwa ukukhangisa kwama-molecule e-cellulose ether emikhiqizweni ye-hydration efana ne-CSH ne-ca(OH)2.Ngenxa yokwanda kwe-viscosity yesisombululo se-pore, i-cellulose ether inciphisa ukuhamba kwama-ion esixazululweni, ngaleyo ndlela ibambezele inqubo ye-hydration.Uma uphezulu ukugcwala kwe-cellulose ether kujeli yamaminerali, kulapho ubonakala khona umphumela wokubambezeleka kokufakwa kwamanzi.I-Cellulose ether ayilibazisi nje kuphela ukusetha, kodwa futhi ibambezela inqubo yokuqina yesistimu yodaka lukasimende.Umphumela wokuvinjelwa kwe-cellulose ether awuncikile kuphela ekugxilweni kwayo ohlelweni lwejeli yamaminerali, kodwa futhi nesakhiwo samakhemikhali.Ukuphakama kwezinga le-methylation ye-HEMC, kuba ngcono umphumela wokuvinjelwa kwe-cellulose ether.Isilinganiso sokushintshwa kwe-hydrophilic esikhundleni sokwandisa amanzi Umphumela wokuhlehlisa unamandla.Kodwa-ke, i-viscosity ye-cellulose ether ayinamthelela omncane ku-simende hydration kinetics.
Ngokukhula kokuqukethwe kwe-hydroxypropyl methylcellulose ether, isikhathi sokusetha sodaka sikhuphuke kakhulu.Kukhona ukuhlobana okuhle okungaqondile phakathi kwesikhathi sokuqala sokusetha sodaka nokuqukethwe kwe-cellulose ether, kanye nokuhlobana okuhle komugqa phakathi kwesikhathi sokugcina sokusetha nokuqukethwe kwe-cellulose ether.Singakwazi ukulawula isikhathi sokusebenza sodaka ngokushintsha inani le-cellulose ether.
