Ama-cellulose ethers, ikakhulukazi ama-hypromellose ethers, ayizingxenye ezibalulekile zodaka lwezentengiselwano. Nge-cellulose ether, i-viscosity yayo iyinkomba ebalulekile yamabhizinisi okukhiqiza udaka, i-viscosity ephezulu isicishe ibe yisidingo esiyisisekelo semboni yodaka. Ngenxa yethonya lobuchwepheshe, inqubo kanye nemishini, kunzima ukuqinisekisa i-viscosity ephezulu yasekhayai-cellulose etherimikhiqizo isikhathi eside. I-Cellulose ether isetshenziswa njenge-ejenti yokugcina amanzi, i-thickener ne-binder emikhiqizweni yodaka, enethonya elikhulu ekusebenzeni kokusebenza, i-viscosity emanzi, isikhathi sokusebenza kanye nemodi yokwakha yesistimu yodaka. Le misebenzi ifezwa ngokuyinhloko isibopho se-hydrogen phakathi kwe-cellulose ether molecule kanye ne-molecule yamanzi kanye nesenzo esisongayo se-cellulose ether molecule, empeleni, ithatha ingxenye yesibopho se-hydrogen ochungechungeni lwamangqamuzana e-cellulose ether futhi yenza buthaka ukuboshwa kwe-cellulose ether, okwenza buthaka ukugcinwa kwamanzi kanye nekhono lokumanzisa le-cellulosether. Abakhiqizi be-Mortar ngokuvamile abazizwa leli phuzu, ngakolunye uhlangothi, imikhiqizo yodaka lwasekhaya namanje ilukhuni, ingakaqapheli ukunaka isigaba sokusebenza kokusebenza, ngakolunye uhlangothi, sikhetha i-viscosity iphakeme kakhulu kune-viscosity edingekayo yobuchwepheshe, le ngxenye nayo inxephezela ukulahlekelwa kokugcinwa kwamanzi, kodwa ku-wettability yonakele.
Ukusebenza kodaka kuthonywa i-cellulose ether equkethe i-extractant enamathelayo enqubweni yokukhiqiza, kuleli phepha, umehluko wamandla okunamathela aqinile phakathi komkhiqizo we-cellulose nomkhiqizo we-cellulose ether owengezwe nge-tackifier ku-ceramic tile adhesive waqinisekiswa ngokuhlolwa. I-Tackifier iwuhlobo lwezinto ezingezwe ngabakhiqizi abathile be-cellulose ether ukuze kulungiswe ukushoda kobuchwepheshe bokukhiqiza, ubuchwepheshe kanye nezisetshenziswa. Ukuba khona kwe-tackifier kwenza ama-molecule amaketanga amade e-cellulose ether cross-link futhi abe njengenetha, okuthinta isivinini sokwakheka kwefilimu ye-cellulose ether kanye nesimo sefilimu, ngaleyo ndlela kuthinte indima ye-cellulose ether odakeni, ithonya lokubuka ngqo liwukuthi: amandla okunamathela aqinile ashintshile ngaphansi kwesimo ngasinye sokuphulukisa; isikhathi sokubeka udaka siyandiswa.
1.Ngaphansi kwesimo sokuphulukisa esijwayelekile, ukungezwa kwe-tackifier ne-cellulose ether ngaphandle kwe-tackifier enqubweni yokukhiqiza kunomphumela othile emandleni okunamathela aqinile we-adhesive tile ye-ceramic, imikhiqizo engezwe nge-tackifier ohlelweni lokukhiqiza inamandla amakhulu okunamathela aqinile.
2.Esicini sokumelana namanzi, amandla okunamathela okuqinile we-adhesive tile ye-ceramic ene-cellulose ether eyengeziwe ye-tackifier enqubweni yokukhiqiza yimbi kakhulu kunaleyo yomkhiqizo ngaphandle kwe-tackifier kwinqubo evamile yokukhiqiza, i-cellulose ether equkethe i-tackifier ithinta ukumelana kwamanzi kwe-adhesive tile.
3. Mayelana nesikhathi sokusetha umoya,i-cellulose ethernge-tackifier yayisetshenziswa ekunamatheleni kwamathayili, amandla ayo okunamathela aqinile ayephansi kunalawo omkhiqizo ngaphandle kwe-tackifier, futhi isikhathi sokuvula safinyezwa.
4.Ngokuqondene nesikhathi sokusetha, isivinini sokuphulukisa se-cellulose ether ceramic tile adhesive ngaphandle kokwengeza i-tackifier ngaphansi kwenqubo evamile yokukhiqiza iyashesha. Kafushane, ukuba khona kwe-tackifier, isenzo sokuxhumanisa okwenza isixazululo se-cellulose ether sibe nesithiyo esiphezulu se-steric, esiboniswa ukuthi siphezulu ekuhlolweni, kodwa ukuba khona kwe-tackifier kuthinta izici eziningi ezibalulekile zesicelo se-cellulose ether, njengokumelana namanzi, isikhathi sokuvula, ukumanzisa nokunye. Eqinisweni, i-viscosity ingenye yezinkomba zokusebenza ze-cellulose ether, i-viscosity ayiyona inkomba ebalulekile yokusebenza okuphelele kwe-cellulose ether, kodwa uhlobo nokuqukethwe kwamaqembu kufanele kube ukugxila kwabakhiqizi bedaka.
5. Futhi kungenxa yokuthi abakhiqizi bakadaka banaka kakhulu i-viscosity, okwenza amabhizinisi athile okukhiqiza i-cellulose ether akhulise i-viscosity ngokusebenzisa izinto ezengeziwe ukuze ahlangabezane nezidingo zabakhiqizi bakadaka, futhi lolu hlobo lwemikhiqizo lune-viscosity ephezulu ebonakalayo, ukusebenza kwayo okuphelele kufaneleka ukunakwa kwabasebenzisi, futhi okubonakalayo okubonakalayo okuphezulu kwe-viscosity okwakhiwa yi-viscosity ephezulu okwakhiwa yi-viscosity ephansi okuyinto abakhiqizi bakadaka abalindele, kodwa empeleni ayikho. Ukuze ukhethe i-cellulose ether, okuyingxenye ebalulekile yokusetshenziswa kodaka, amabhizinisi odaka aphishekela ikhwalithi ephezulu futhi ezinzile adinga ukwazi ulwazi oluthile ngemuva, lokhu kuzoba usizo kubakhiqizi ukuthuthukisa imikhiqizo esebenza kahle, ukuqinisekisa ukuzinza kwekhwalithi yomkhiqizo.
