Kwangeminyaka yoo-1930, izibophelelo zepolymer zazisetyenziselwa ukuphucula ukusebenza kodaka. Emva kokuba i-lotion ye-polymer ifakwe ngempumelelo kwimarike, i-Walker yaphuhlisa inkqubo yokumisa isitshizi, eyaqaphela ukunikezelwa kwe-lotion ngendlela yomgubo werabha, yaba sisiqalo sexesha le-polymer eguqulwe ngodaka oluxubeneyo olomileyo.
Kwiminyaka engaphezu kwe-100, iithayile ze-ceramic zisetyenziswe njengezinto zokugquma iindonga kunye nemigangatho. Kule mihla, ziye zaba zizinto eziyimfuneko zokuhombisa. Iithayile zobukhulu obahlukeneyo, iipateni, kunye namabanga zinokubonwa kuyo yonke indawo. Ngokuhambela phambili kwetekhnoloji yeethayile ze-ceramic, umzimba weethayile ze-ceramic uya uxinene ngakumbi kwaye ube mkhulu ngobungakanani, ubeka imiceli mngeni enkulu yokubekwa kweethayile ze-ceramic. Indlela yokwenza iithayile ze-ceramic ezinobungakanani obukhulu zinamathele ngakumbi kwaye ziqinisekise ukuthembeka kokubeka ixesha elide kuye kwaba yingqwalasela entsha kwinkalo yokuhlobisa yanamhlanje. Izinto zokuncamathelisa (ezifana nepolymer) zimanziswe kumphezulu weethayile ze-ceramic, zenza imeko yokumanzisa phakathi kwezi zimbini, okukhokelela kwisithuba esincinci kakhulu semolekyuli phakathi kwezi zimbini. Ekugqibeleni, amandla amakhulu e-intermolecular ayenziwa kwi-interface yokudibanisa, idibanisa ngokuqinileyo izinto ezincamathelayo kunye nethayile ye-ceramic. Ngokuhambela phambili kwetekhnoloji yethayile ye-ceramic, iithayile ze-ceramic ezixineneyo ngokwandayo kunzima ukunika izikhewu ezingakumbi zokudityaniswa koomatshini ukwenza i-ankile. Nangona kunjalo, i-intermolecular bonding iya ibaluleke kakhulu.
I-latex powder enokuchithwa kwakhona (iRDP) yenza inethiwekhi yepolymer kwiimveliso zodaka, ukudibanisa iileyile kunye nodaka ngokusebenzisa amandla e-intermolecular. Nangona iileyile zixinene, zinokubambelela ngokuqinileyo kumdaka. I-latex powder enokuchithwa kwakhona yenziwa yi-polymerization yeepolymers ezimbini okanye ngaphezulu, kwaye inobunzima obahlukeneyo ngokusekelwe kwimilinganiselo eyahlukeneyo yokubunjwa kwe-polymer. Xa ukwimeko yobushushu obuphezulu, umgubo werabha uya kubonisa amanqanaba ahlukeneyo okuthambisa ngenxa yobunzima bawo. Ubunzima bepowder adhesive, iqondo eliphantsi lokuthambisa kwiqondo lokushisa elifanayo, kwaye linamandla okukwazi ukuxhathisa amandla angaphandle kumaqondo aphezulu. Ngoko ke, i-powder adhesive esetyenziswe kwi-ceramic tile adhesive, i-preority ifanele inikwe ekukhetheni ukuqina okuphezulu kwe-powder adhesive, enokuqinisekisa ngokufanelekileyo ukubambelela kwexesha elide kwiindawo eziphezulu zokushisa. Xa usebenzisa indlela yokwakhiwa kwe-tile yokwakhiwa kwe-tile, ukwenzela ukuba kube lula ukwakhiwa, abasebenzi baya kukhetha ukusebenzisa i-glue kwindawo enkulu ngaphambi kokuba baqhubele phambili nomsebenzi we-tile. Ngethuba le nkqubo, i-adhesive tile ye-ceramic iya kwenza ulusu kwindawo evezwe ngenxa yesantya somoya wendalo, i-substrate ye-absorption yamanzi, kunye ne-cellulose ether yangaphakathi yokuchithwa kunye nokunyakaza. Ngenxa yokuba ukumanzisa kuyisitshixo sokubambisana okusondeleyo kwezinto, xa i-crust inzima ukuphuka, kuya kwenza kube nzima ukuba i-adhesive tile imanzise i-tile surface, ekugqibeleni ichaphazele amandla okudibanisa. Ukukhetha i-latex powder ehlaziywayo, kwelinye icala, ngenxa yesakhiwo sayo, inokudlala indima ethile ekugcinweni kwamanzi, ukulibazisa izinga le-hydration kunye nesikhumba. Ngakolunye uhlangothi, inokuphucula amandla okubambelela kwindawo nganye yeyunithi, nokuba indawo yokungena iyancitshiswa, isenokuqinisekisa amandla okubambelela ngokubanzi. Kwangaxeshanye, kubaluleke kakhulu ukukhetha i-cellulose ether ngokufanelekileyo. Njengoko ubungakanani beethayile ze-ceramic bukhula, kuya kuba lula ukufumana umngxuma kunye nokuvela kwe-ceramic tile detachment emva kokubeka. Lo mbandela uhambelana ngokusondeleyo nokuguquguquka kwezinto zokudibanisa. Iithayile zeCeramic zinokuxinana okuphezulu kunye nokuguqulwa okuphantsi, kwaye umaleko wesiseko unokufumana ukuguqulwa okubalulekileyo ngenxa yezinto ezahlukeneyo zangaphandle nangaphakathi. I-adhesive tile ye-ceramic esetyenziswe njengoluhlu lwe-bonding kufuneka ikwazi ukufumana uxinzelelo oluveliswa yi-deformation. Ukuba i-tile ye-ceramic i-adhesive ayiqukethe i-powder adhesive okanye inomxholo ophantsi we-adhesive powder, kuya kuba nzima ukufumana uxinzelelo olubangelwa yi-deformation, ebangela ukuba yonke inkqubo ye-paving iyancipha ngokuthe ngcembe kwiindawo ezibuthathaka, zenza iidramu ezingenanto.
I-powder ye-latex ye-redispersible inokubonelela nge-adhesive tile kunye nokukwazi ukulungelelanisa ukuguqulwa koxinzelelo, okuphucula ukuguquguquka kwe-adhesive tile. Kule nkqubo, ukuqina kwe-ceramic tile adhesive ikakhulukazi kubonelelwa ngezinto ezingaphiliyo ezifana nesamente kunye nesanti, ngelixa ukuguquguquka kunikezelwa ngumgubo wokubambelela. I-polymer ingena ngeepores zamatye e-samente, yenza inethiwekhi ye-polymer esebenza njenge-elastic bond phakathi kwezinto eziqinileyo, inika ukuguquguquka. Xa i-deformation isenzeka, inethiwekhi yepolymer inokuthatha uxinzelelo, iqinisekise ukuba izinto eziqinileyo aziqhekeki okanye zonakalise. Ke ngoko, ukuphuculwa kokuguquguquka kwezinto zokuncamathelisa kubalulekile ekunciphiseni umngxuma. Ubungakanani obufanelekileyo bepowder adhesive inokuphucula ukubunjwa kwesakhiwo senethiwekhi yepolymer ngaphakathi kwe-adhesive tile tile.
