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 yenziwa 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 ukugcina amanzi kanye nekhono lokumanzisa le-cellulose ether.Abakhiqizi bodaka ikakhulukazi abazizwa leli phuzu, ngakolunye uhlangothi, imikhiqizo yodaka lwasekhaya namanje ilukhuni, abakakaqapheli ukunaka isigaba sokusebenza kokusebenza, ngakolunye uhlangothi, sikhetha i-viscosity ephakeme kakhulu. kune-viscosity edingekayo yobuchwepheshe, le ngxenye iphinde yakhokhela ukulahlekelwa kokugcinwa kwamanzi, kodwa ekumanzini konakele.
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 eketango elide le-cellulose ether cross-link futhi afane nenethi, okuthinta ijubane lokwakheka kwefilimu ye-cellulose ether kanye nesimo sefilimu, ngaleyo ndlela kuthinte indima ye-cellulose ether odakeni, i-direct- ithonya lokubuka 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 kunomthelela othile emandleni okunamathela aqinile we-adhesive tile ye-ceramic, imikhiqizo engezwe nge-tackifier ohlelweni lokukhiqiza inamandla amakhulu okunamathela aqinile. .
2.Engxenyeni yokumelana namanzi, amandla okunamathela okuqinile we-adhesive tile ye-ceramic ene-cellulose ether eyengeziwe ye-tackifier enqubweni yokukhiqiza yimbi kakhulu kunaleyo yomkhiqizo ngaphandle kwe-tackifier enqubweni evamile yokukhiqiza, i-cellulose ether equkethe i-tackifier ithinta amanzi. ukumelana ne-adhesive tile.
3. Ngokwesikhathi 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 samanzi se-cellulose ether sibe nesithiyo esiphezulu se-steric, esiboniswa siphezulu ekuhlolweni, kodwa ukuba khona kwe-tackifier kuthinta izici eziningi ezibalulekile zokusetshenziswa kwe-cellulose. i-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.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 kuphela, ebanzi. ukusebenza kufanele ukunakwa kwabasebenzisi, futhi i-viscosity ephezulu ebonakalayo eyenziwe ngokukhula kwe-viscosity ayikwazi ukufeza ithiyori “yokuqukethwe okuphansi kwe-viscosity ephansi” abakhiqizi bedaka abayilindele, 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.
