Oku akuncedi nje ukuphucula amandla okubambisana kwe-adhesive tile, kodwa kwandisa ixesha lokuvula, okwenza ukulungiswa kweetayile kuguquguquke ngakumbi ngexesha lokwakha. Ukongezelela, ukusebenza kokugcinwa kwamanzi kwe-HEMC kunokuphepha ngokufanelekileyo ukulahleka kwamanzi ngokukhawuleza kwiindawo ezomileyo, ngaloo ndlela kuncitshiswe ukuvela kokuqhekeka okomileyo, ukukhupha kunye nezinye iingxaki.
b. Ukuphucula ukusebenza kunye nokumelana nokutyibilika
Umphumo wokuqina we-HEMC unokunyusa i-viscosity ye-adhesive, ngaloo ndlela iphucula ukusebenza kwayo yokwakha. Ngokulungelelanisa inani le-HEMC elongeziweyo, i-adhesive ingaba ne-thixotropy enhle ngexesha lenkqubo yokwakha, oko kukuthi, ukunyuka kwe-fluidity kuyanda phantsi kwesenzo samandla angaphandle, kwaye ngokukhawuleza kubuyela kwisimo esiphezulu se-viscosity emva kokuba amandla angaphandle amisiwe. Olu phawu aluncedi nje ukuphucula ukuzinza kweetayile ze-ceramic ngexesha lokubeka, kodwa kunciphisa ukuvela kwe-slippage kunye nokuqinisekisa ukuguquguquka kunye nokuchaneka kwe-tile ye-ceramic.
c. Ukuphucula amandla okudibanisa
I-HEMC inokuphucula amandla angaphakathi okwakhiwa kwe-adhesive, ngaloo ndlela iphucula umphumo wayo wokudibanisa kwi-substrate kunye ne-ceramic tile surface. Ngokukodwa kwiindawo zokwakha ezinokushisa okuphezulu okanye ukufuma okuphezulu, i-HEMC inokunceda i-adhesive igcine ukusebenza kokubambisana okuzinzile. Oku kungenxa yokuba i-HEMC inokuzinzisa inkqubo ngexesha lokwakha, iqinisekisa ukuba i-hydration reaction ye-samente kunye nezinye izinto ezisisiseko zihamba kakuhle, ngaloo ndlela ziphucula amandla okubambisana kunye nokuqina kwe-adhesive tile.
3. Idosi ye-HEMC kunye nebhalansi yokusebenza
Isixa se-HEMC sidlala indima ebalulekileyo ekusebenzeni kwe-adhesive tile. Ngokuqhelekileyo, inani elongezelelweyo le-HEMC liphakathi kwe-0.1% kunye ne-1.0%, enokulungiswa ngokuhambelana neendawo ezahlukeneyo zokwakha kunye neemfuno. Idosi ephantsi kakhulu inokubangela ukugcinwa kwamanzi okwaneleyo, ngelixa idosi ephezulu kakhulu inokubangela ukungahambi kakuhle kwamanzi okunamathelayo, okuchaphazela umphumo wokwakha. Ngoko ke, kwizicelo ezisebenzayo, kuyimfuneko ukuqwalasela ngokubanzi indawo yokwakha, iipropati ze-substrate, kunye neemfuno zokugqibela zokwakha, kunye nokulungelelanisa ngokufanelekileyo inani le-HEMC ukuqinisekisa ukuba i-viscosity, ixesha lokuvula, kunye namandla okubambelela kufikelela kwi-balance balance.
4. Izibonelelo zokusetyenziswa kwe-HEMC
Ukulungelelaniswa kolwakhiwo: Ukusetyenziswa kwe-HEMC kunokuphucula ukusebenza kokwakhiwa kweetayile ze-ceramic adhesives, ngokukodwa kwindawo enkulu yokupaka kunye neendawo ezinzima, okwenza inkqubo yokwakha ibe lula.
Ukuqina: Ekubeni i-HEMC inokuphucula ukugcinwa kwamanzi kunye nokuqina kokubambisana kwe-adhesive, i-tile yokubopha i-tile emva kokwakhiwa izinzile kwaye iqinile.
