I-adhesive-based tile adhesive okwamanje iwukusetshenziswa okukhulu kakhulu kodaka olukhethekile oluxutshwe okomile, olwakhiwe usimende njengento eyinhloko kasimende futhi yengezwe ngamaqoqo ahlanganisiwe, ama-agent okugcina amanzi, ama-ejenti wamandla okuqala, i-latex powder nezinye izithasiselo eziphilayo noma ezingaphili. ingxube. Ngokuvamile, idinga kuphela ukuxutshwa namanzi lapho isetshenziswa. Uma kuqhathaniswa nodaka olujwayelekile lukasimende, lungathuthukisa kakhulu amandla okubopha phakathi kwezinto ezibhekene ne-substrate, futhi linokumelana okuhle kokushelela kanye nokumelana kwamanzi okuhle kakhulu nokumelana nokushisa. Futhi izinzuzo zokumelana nomjikelezo we-freeze-thaw, ikakhulukazi osetshenziselwa ukunamathisela amathayela odonga lwangaphakathi nangaphandle, amathayela aphansi nezinye izinto zokuhlobisa, ezisetshenziswa kakhulu ezindongeni zangaphakathi nangaphandle, phansi, izindlu zangasese, amakhishi nezinye izindawo zokuhlobisa izakhiwo, okwamanje Izinto ezisetshenziswa kakhulu ze-ceramic tile bonding.
Ngokuvamile lapho sahlulela ukusebenza kwe-adhesive ye-tile, asigcini nje ukunaka ukusebenza kwayo nokusebenza nekhono lokulwa nokuslayida, kodwa futhi sinake amandla ayo emishini kanye nesikhathi sokuvula. I-cellulose ether ku-adhesive tile ayithinti nje kuphela izakhiwo ze-rheological ze-adhesive porcelain, njengokusebenza okushelelayo, ummese wokunamathela, njll., kodwa futhi inethonya elinamandla ezintweni zemishini zokunamathisela i-tile.
1. Amahora okuvula
Lapho impushana yenjoloba ne-cellulose ether kuhlangene odakeni olumanzi, amanye amamodeli edatha abonisa ukuthi impushana yenjoloba inamandla e-kinetic anamandla okunamathisela emikhiqizweni ye-cement hydration, futhi i-cellulose ether ikhona kakhulu ku-interstitial fluid, ethinta i-Mortar viscosity eyengeziwe nesikhathi sokumisa. Ukungezwani okungaphezulu kwe-cellulose ether kukhulu kunaleyo yempushana yerabha, futhi i-cellulose ether eyengeziwe ehlanganiswe esixhumi esibonakalayo sosimende kuyoba yinzuzo ekwakhekeni kwamabhondi e-hydrogen phakathi kwendawo eyisisekelo ne-cellulose ether.
Odakeni olumanzi, amanzi odaka ayahwamuka, futhi i-cellulose ether iyacetshiswa phezulu, futhi ifilimu izokwakhiwa ebusweni bodaka kungakapheli imizuzu emi-5, okuzonciphisa izinga lokuhwamuka okulandelayo, njengoba amanzi engeziwe ekhishwa. isuswe odakeni olujiyile Ingxenye yayo ithuthela ongqimbeni oluncane lodaka, futhi ifilimu eyakhiwe ekuqaleni iyancibilika kancane, futhi ukufuduka kwamanzi kuzoletha ukunothisa kwe-cellulose ether ngaphezulu kodaka.
Ukwakhiwa kwefilimu ye-cellulose ether ebusweni bodaka kunethonya elikhulu ekusebenzeni kodaka:
1. Ifilimu eyenziwe incane kakhulu futhi izohlakazwa kabili, ayikwazi ukukhawulela ukuhwamuka kwamanzi nokunciphisa amandla.
2. Ifilimu eyenziwe iminyene kakhulu. Ukuhlushwa kwe-cellulose ether oketshezini lwe-mortar interstitial kuphezulu futhi i-viscosity iphezulu. Akulula ukuphula ifilimu engaphezulu lapho ama-tile enamathiselwe.
Kungabonakala ukuthi izakhiwo zefilimu ze-cellulose ether zinomthelela omkhulu ngesikhathi esivulekile. Uhlobo lwe-cellulose ether (i-HPMC, i-HEMC, i-MC, njll.) kanye nezinga le-etherification (i-substitution degree) kuthinta ngokuqondile izakhiwo zefilimu ze-cellulose ether, kanye nobulukhuni nokuqina kwefilimu.
