Kusukela ngawo-1930s, izibophezelo ze-polymer zazisetshenziselwa ukuthuthukisa ukusebenza kodaka. Ngemva kokufakwa ngempumelelo kwe-polymer lotion emakethe, u-Walker wasungula inqubo yokumisa isifutho, eyaqaphela ukuhlinzekwa kwesithambiso sempushana yenjoloba, kwaba ukuqala kwenkathi yodaka oluxubile olomile lwe-polymer.
Sekuyiminyaka engaphezu kwe-100, amathayela e-ceramic asetshenziswa njengesembozo sezindonga naphansi. Namuhla, sebephenduke izinto zokuhlobisa ezibalulekile. Amathayela anobukhulu obuhlukahlukene, amaphethini, namabanga angabonakala yonke indawo. Ngokuthuthuka kobuchwepheshe bamathayela e-ceramic, umzimba wamathayela e-ceramic uya ngokuya uminyene futhi uba mkhulu ngosayizi, okuletha izinselelo ezinkulu zokubekwa kwamathayela e-ceramic. Indlela yokwenza amathayela e-ceramic amakhulu anamathele ngokuqinile futhi uqinisekise ukuthembeka kokubeka isikhathi eside sekugxilwe okusha emkhakheni wokuhlobisa wesimanje. Izinto zokunamathisela (njenge-polymer) zimanziswa phezu kwamathayela e-ceramic, okwenza isimo sokumanzisa phakathi kwakho kokubili, okuholela esikhaleni esincane kakhulu samangqamuzana phakathi kwakho kokubili. Ekugcineni, kwakheka amandla amakhulu e-intermolecular esixhumi esibonakalayo esibophayo, ebopha ngokuqinile into enamathelayo ngethayela le-ceramic. Ngokuthuthuka kobuchwepheshe bamathayela e-ceramic, amathayela e-ceramic aminyene ngokuya kunzima ukuhlinzeka ngezikhala ezengeziwe zokuxhumanisa ngomshini ukuze akhe i-anchoring. Kodwa-ke, ukuhlanganiswa kwama-intermolecular kuya ngokuya kubaluleke kakhulu.
Impushana ye-latex ehlakazeka kabusha (I-RDP) yakha inethiwekhi ye-polymer emikhiqizweni yodaka, ehlanganisa amathayili nodaka ngokusebenzisa amandla e-intermolecular. Ngisho noma amathayili aminyene, angakwazi ukunamathela ngokuqinile odongeni. Impushana ye-latex ehlakazeka kabusha yenziwa i-polymerization yama-polymers amabili noma ngaphezulu, futhi inobunzima obuhlukile obusekelwe ezingxenyeni ezihlukene zokubunjwa kwe-polymer. Uma isesimweni sokushisa okuphezulu, impushana yerabha izobonisa amazinga ahlukene okuthambisa ngenxa yokuqina kwayo. I-adhesive powder iqina, iyancipha izinga lokuthambisa ezingeni lokushisa elifanayo, futhi inamandla amakhulu okumelana namandla angaphandle emazingeni okushisa aphezulu. Ngakho-ke, i-powder enamathelayo esetshenziselwa ukunamathela kwe-ceramic tile, okubaluleke kakhulu kufanele kunikezwe ekukhetheni i-powder enamathela yobulukhuni, engaqinisekisa ngokuphumelelayo ukunamathela isikhathi eside ezindaweni ezishisa kakhulu. Uma usebenzisa indlela yokwakha ungqimba oluncane lokwakhiwa kwe-tile, ukuze kube lula ukwakhiwa, abasebenzi bazokhetha ukusebenzisa i-glue endaweni enkulu ngaphambi kokuqhubeka nomsebenzi wokufaka amathayela. Phakathi nale nqubo, i-ceramic tile adhesive izokwakha isikhumba endaweni eveziwe ngenxa yesivinini somoya wemvelo, ukumuncwa kwamanzi e-substrate, kanye nokuchithwa kwe-cellulose ether yangaphakathi nokunyakaza. Ngenxa yokuthi ukumanzisa kuyisihluthulelo sokusondelana kwezinto ezibonakalayo, lapho uqweqwe lunzima ukuphuka, kuzokwenza kube nzima ukuthi i-adhesive tile imanzise i-tile surface, ekugcineni ithinte amandla okubopha. Ukukhetha i-latex powder ephinda ihlakazeka, ngakolunye uhlangothi, ngenxa yesakhiwo sayo, ingadlala indima ethile ekugcineni amanzi, ibambezele izinga le-hydration kanye nesikhumba. Ngakolunye uhlangothi, ingakwazi ukuthuthukisa amandla okunamathela endaweni ngayinye yeyunithi, ngisho noma indawo yokungena incishisiwe, isengakwazi ukuqinisekisa amandla okunamathela jikelele. Ngesikhathi esifanayo, kubaluleke kakhulu ukukhetha i-cellulose ether ngokunengqondo. Njengoba ubukhulu bamathayela e-ceramic bukhula, kuya ngokuya kuba lula ukuzwa ukugoba ngisho nokuvela kokuqoqwa kwamathayela e-ceramic ngemva kokubekwa. Lolu daba luhlobene eduze nokuguquguquka kwezinto ezibophayo. Amathayela e-Ceramic anokuminyana okuphezulu nokuwohloka okuphansi, futhi isendlalelo sesisekelo singase sibe nokuguga okuphawulekayo ngenxa yezici ezihlukahlukene zangaphandle nezangaphakathi. I-adhesive tile ye-ceramic esetshenziswa njengesendlalelo sokubopha kufanele ikwazi ukumunca ukucindezeleka okukhiqizwa ukuguqulwa. Uma i-adhesive tile ye-ceramic ingenayo i-adhesive powder noma inokuqukethwe okuphansi kwe-adhesive powder, kuyoba nzima ukudonsa ukucindezeleka okubangelwa ukuguqulwa, okubangela ukuthi lonke uhlelo lwe-paving luwa kancane kancane ezindaweni ezibuthakathaka, zenze izigubhu ezingenalutho.
I-latex powder e-redispersible ingahlinzeka nge-adhesive ye-tile enekhono lokuzivumelanisa nokuguqulwa kokucindezeleka, okuthuthukisa ukuguquguquka kwe-adhesive tile. Kulolu hlelo, ukuqina kwe-ceramic tile adhesive ikakhulukazi kuhlinzekwa ngezinto ezingaphili ezifana nosimende nesihlabathi, kuyilapho ukuguquguquka kunikezwa impushana yokunamathela. I-polymer ingena ngezimbotshana zetshe likasimende, yakha inethiwekhi ye-polymer esebenza njengesibopho esinwebekayo phakathi kwezingxenye eziqinile, inikeze ukuguquguquka. Uma kwenzeka ukuguqulwa, inethiwekhi ye-polymer ingakwazi ukumunca ukucindezeleka, iqinisekise ukuthi izingxenye eziqinile aziqhekeki noma zilimale. Ngakho-ke, ukwenza ngcono ukuguquguquka kwezinto zokunamathela kubalulekile ekwehliseni umgodi. Inani elifanele le-powder elinamathelayo lingathuthukisa ukwakheka kwesakhiwo senethiwekhi ye-polymer ngaphakathi kwe-adhesive tile ye-ceramic.
