Ukunamathiswa kwethayile esekwe kwisamente okwangoku kusesona sicelo sikhulu sodaka olukhethekileyo oluxutyiweyo, oluqulunqwe ngesamente njengeyona nto iphambili yesamente kwaye yongezwa ngamabakala adityanisiweyo, iiarhente zokugcina amanzi, iiarhente zamandla okuqala, umgubo welatex kunye nezinye izongezo zendalo okanye ezingaphiliyo. umxube.Ngokuqhelekileyo, kufuneka ixutywe namanzi kuphela xa isetyenziswa.Xa kuthelekiswa nodaka lwesamente oluqhelekileyo, lunokuphucula kakhulu amandla okudibanisa phakathi kwezinto ezijongeneyo kunye ne-substrate, kwaye inokumelana nokutyibilika okulungileyo kunye nokuchasana kwamanzi okugqwesileyo kunye nokuxhathisa ubushushu.Kwaye iingenelo zokuxhathisa umjikelo wokuqhwala, ikakhulu ezisetyenziselwa ukuncamathelisa iithayile zodonga lwangaphakathi kunye nangaphandle, iithayile zomgangatho kunye nezinye izinto zokuhombisa, ezisetyenziswa ngokubanzi kwiindonga zangaphakathi nangaphandle, imigangatho, amagumbi okuhlambela, iikhitshi kunye nezinye iindawo zokuhombisa izakhiwo, okwangoku eyona nto isetyenziswa ngokubanzi i-ceramic tile bonding imathiriyeli.
Ngokuqhelekileyo xa sigweba ukusebenza kwe-adhesive ye-tile, asiyi kuqwalasela kuphela ukusebenza kwayo kunye nekhono lokuchasana ne-sliding, kodwa sinikele ingqalelo kumandla ayo omatshini kunye nexesha lokuvula.I-cellulose ether kwi-adhesive tile ayichaphazeli nje kuphela iimpawu ze-rheological ze-adhesive porcelain, ezifana nokusebenza kakuhle, imela yokuncamathela, njl.
1. Iiyure zokuvula
Xa umgubo werabha kunye neselulosi ether zikho kudaka olumanzi, ezinye iimodeli zedatha zibonisa ukuba umgubo werabha unamandla e-kinetic anamandla okuncamathisela kwimveliso yesamente ye-hydration, kunye ne-cellulose ether ikhona ngakumbi kwi-interstitial fluid, echaphazela ngakumbi i-Mortar viscosity kunye nexesha lokubeka.Uxinzelelo lomphezulu we-cellulose ether mkhulu kunomgubo werabha, kwaye i-ether ye-cellulose eyongeziweyo kwi-interface yodaka iya kuba luncedo ekubunjweni kweebhondi ze-hydrogen phakathi komgangatho wesiseko kunye ne-cellulose ether.
Kudaka olumanzi, amanzi kumdaka aphuphuma, kwaye i-cellulose ether iyatyetyiswa phezu komhlaba, kwaye ifilimu iya kwenziwa phezu kodaka ngaphakathi kwemizuzu emi-5, eya kunciphisa izinga lokunyuka komphunga, njengoko amanzi amaninzi enziwa. isuswe kudaka olungqindilili Inxalenye yayo ifudukela kumaleko odaka obhityileyo, kwaye ifilimu eyenziwe ekuqaleni ichithwa ngokuyinxenye, kwaye ukufuduka kwamanzi kuya kuzisa ngakumbi ukutyetyiswa kwe-cellulose etere kumphezulu wodaka.
Ukwenziwa kwefilimu ye-cellulose ether kumphezulu wodaka kunempembelelo enkulu ekusebenzeni kodaka:
1. Ifilimu eyenziwe incinci kwaye iya kuchithwa kabini, ayikwazi ukukhawulela ukukhuphuka kwamanzi kunye nokunciphisa amandla.
2. Ifilimu eyenziweyo inzima kakhulu.Uxinzelelo lwe-cellulose ether kulwelo lwe-mortar interstitial luphezulu kwaye i-viscosity iphezulu.Akulula ukuphula ifilimu yomhlaba xa iileyili zifakwe.
Ingabonwa ukuba iipropati zokwenza ifilimu ye-cellulose ether inempembelelo enkulu kwixesha elivulekileyo.Uhlobo lwe-cellulose ether (i-HPMC, i-HEMC, i-MC, njl.) kunye ne-degree of etherification (i-substitution degree) ichaphazela ngokuthe ngqo iipropati zefilimu ze-cellulose ether, kunye nobunzima kunye nokuqina kwefilimu.
