Ama-ether e-cellulose, ikakhulukazi ama-ether e-hypromellose, ayizingxenye ezibalulekile zama-mortar ezentengiselwano. Ku-cellulose ether, i-viscosity yayo iyinkomba ebalulekile yamabhizinisi okukhiqiza i-mortar, i-viscosity ephezulu cishe isibe yisidingo esiyisisekelo semboni ye-mortar. Ngenxa yethonya lobuchwepheshe, inqubo kanye nemishini, kunzima ukuqinisekisa i-viscosity ephezulu yasekhaya.i-cellulose etherimikhiqizo isikhathi eside. I-Cellulose ether isetshenziswa njenge-ejenti yokugcina amanzi, i-thickener kanye ne-binder emikhiqizweni ye-mortar, enethonya elikhulu ekusebenzeni kokusebenza, i-viscosity emanzi, isikhathi sokusebenza kanye nemodi yokwakha yesistimu ye-mortar. Le misebenzi ifezwa kakhulu yi-hydrogen bond phakathi kwe-molecule ye-cellulose ether ne-molecule yamanzi kanye nesenzo sokugoqa se-molecule ye-cellulose ether, empeleni, ithatha ingxenye ye-hydrogen bond ku-cellulose ether molecular chain futhi ibuthakathaka ukubhajwa kwe-cellulose ether, okwenza buthaka ukugcinwa kwamanzi kanye nekhono lokumanzisa le-cellulose ether. Abakhiqizi be-mortar ikakhulukazi abazizwa ngaleli phuzu, ngakolunye uhlangothi, imikhiqizo ye-mortar yasekhaya isalukhuni, abakaqapheli ukunaka isigaba sokusebenza kokusebenza, ngakolunye uhlangothi, sikhetha i-viscosity iphakeme kakhulu kune-viscosity edingekayo yobuchwepheshe, le ngxenye iphinde yanxeshezelwa ukulahlekelwa ukugcinwa kwamanzi, kodwa ekubunjweni kokumanzi kuyalimala.
Ukusebenza kodaka kuthonywa yi-cellulose ether equkethe i-adhesive extractant enqubweni yokukhiqiza, kuleli phepha, umehluko wamandla okunamathela okuqinile phakathi komkhiqizo we-cellulose nomkhiqizo we-cellulose ether owengezwe nge-tackifier ku-ceramic tile adhesive waqinisekiswa ngokuhlolwa. I-Tackifier uhlobo lwezinto ezingezwe abanye abakhiqizi be-cellulose ether ukuze balungise ukushoda kobuchwepheshe bokukhiqiza, ubuchwepheshe kanye nemishini. Ukuba khona kwe-tackifier kwenza ama-molecule amade e-cellulose ether cross-link abe yi-net-like, okuthinta isivinini sokwakheka kwefilimu ye-cellulose ether kanye nesimo sefilimu, ngaleyo ndlela kuthinte indima ye-cellulose ether kudaka, ithonya lokubuka ngqo yileli: amandla okunamathela okuqinile ashintshile ngaphansi kwesimo ngasinye sokuphiliswa; isikhathi sokusetha kodaka siyandiswa.
1. Ngaphansi kwesimo esijwayelekile sokwelapha, ukungezwa kwe-tackifier kanye ne-cellulose ether ngaphandle kwe-tackifier enqubweni yokukhiqiza kunomthelela othile emandleni okunamathela okunamathelayo kwe-ceramic tile anamathelayo, imikhiqizo engezwe nge-tackifier enqubweni yokukhiqiza inamandla okunamathela okunamathelayo aphezulu.
2. Esicini sokumelana namanzi, amandla okunamathela okuqinile kwe-ceramic tile anamathelayo ane-cellulose ether engeziwe enqubweni yokukhiqiza mabi kakhulu kunalawo omkhiqizo ongena-tackifier enqubweni yokukhiqiza evamile, i-cellulose ether equkethe i-tackifier ithinta ukumelana namanzi kwe-tile anamathelayo.
3. Ngokuphathelene nesikhathi sokusetha umoya,i-cellulose ethernge-tackifier yayisetshenziswa ku-tackifier yethayela, amandla ayo okunamathela athambile ayephansi kunalawo omkhiqizo ngaphandle kwe-tackifier, futhi isikhathi sokuvula safinyezwa.
4. Ngokuphathelene nesikhathi sokusetha, ijubane lokuqiniswa kwe-cellulose ether ceramic tile adhesive ngaphandle kokwengeza i-tackifier ngaphansi kwenqubo evamile yokukhiqiza lishesha kakhulu. Ngamafuphi, ukuba khona kwe-tackifier, isenzo sokuxhumanisa esenza isixazululo samanzi se-cellulose ether sibe nesithiyo esiphezulu se-steric, okuboniswa ukuthi siphezulu esivivinyweni, kodwa ukuba khona kwe-tackifier kuthinta izakhiwo eziningi ezibalulekile zokusetshenziswa kwe-cellulose ether, njengokumelana namanzi, isikhathi sokuvula, ukumanzisa njalo njalo. Eqinisweni, i-viscosity ingenye yezikhombisi zokusebenza ze-cellulose ether, i-viscosity akuyona inkomba ebalulekile yokusebenza okuphelele kwe-cellulose ether, kodwa uhlobo nokuqukethwe kwamaqembu kufanele kube yinto egxilwe abakhiqizi be-mortar.
5. Futhi kungenxa yokuthi abakhiqizi be-mortar banaka kakhulu i-viscosity, okwenza amanye amabhizinisi okukhiqiza i-cellulose ether andise i-viscosity ngezinto ezengeziwe ukuze ahlangabezane nezidingo zabakhiqizi be-mortar, futhi lolu hlobo lwemikhiqizo lune-viscosity ephezulu ebonakalayo, ukusebenza kwalo okuphelele kufanele kuqashelwe abasebenzisi, futhi i-viscosity ephezulu ebonakalayo eyakhiwe yi-viscosity ekhulayo ayikwazi ukufeza inkolelo-mbono ethi "i-viscosity ephezulu okuqukethwe okuphansi" elindelwe abakhiqizi be-mortar, kodwa empeleni ayikho. Ukuze kukhethwe i-cellulose ether, okuyizinto ezibalulekile zokusetshenziswa ku-mortar, amabhizinisi e-mortar aphishekela ikhwalithi ephezulu nezinzile adinga ukwazi ulwazi oluthile ngemuva, lokhu kuzoba usizo kubakhiqizi ukuthuthukisa imikhiqizo esebenza kahle, ukuqinisekisa ukuzinza kwekhwalithi yomkhiqizo.
