Umgubo wepolymer yinto eyongezwa kwi-adhesive yethayile ukuthintela ukugoba kweetayile. Ukongeza umgubo wepolymer kumxube we-adhesive kuphucula amandla okubopha kwe-adhesive, kudala unxibelelwano oluqinileyo phakathi kwethayile kunye ne-substrate. Iithayile ezingenanto zibonisa ukungabikho konxibelelwano olufanelekileyo phakathi kwethayile kunye ne-substrate, okanye ukungabikho kwe-adhesive phakathi kwemiphezulu emibini. Ekwakhiweni, ukugoba kweetayile ngokwesiko kuye kwathathwa njengengxaki ebalulekileyo ekufuneka ijongwe. Umgubo wepolymer uye wabonakala uphumelela ekuthinteleni ukugoba kweetayile nokuqinisekisa ukufakwa okukhuselekileyo. Eli nqaku lixoxa ngendlela ii-powder zepolymer ezinokuthintela ngayo ukugoba kweetayile ekwakheni.
Iipowder zepolymer zihlala zenziwe ngeepowder zepolymer eziphinda zinyibilike (RDP) kwaye zisetyenziswa kakhulu kwi-premixes, iimortars ezomileyo kunye nee-bonding courses. I-RDP yipowder equlethe umxube we-vinyl acetate kunye ne-ethylene. Umsebenzi we-polymer powder kukuphucula iipropati ze-bonding zomaleko we-bonding, ukwandisa amandla e-bonding eethayile ze-ceramic kunye namandla okutsalwa kwe-adhesive. Umaleko we-bonding uqulethe i-polymer powder enika ukunamathela okuhle kwiintlobo ngeentlobo ze-substrates kubandakanya i-concrete, i-plastered concrete kunye ne-plasterboard.
Umgubo wepolymer usebenza njengesixhobo sokugcina amanzi, uphucula ukuhamba komxube we-binder. Umgubo wepolymer unceda ukugcina umswakama kwi-adhesive, ngaloo ndlela wandisa ixesha lokomisa kwe-adhesive. Ngenxa yenkqubo yokomisa ecothayo, i-adhesive ingangena kwi-tile nakwi-substrate surfaces, idale i-bond eqinileyo. Umxube we-adhesive otyebileyo nohlala ucothayo unceda ukuthintela ukugoba kwe-adhesive ngokuqinisekisa ukuba ii-adhesive zifakwe kwi-adhesive kwaye aziyi kuphuma ngexesha lokufakwa.
Ukongeza, umgubo wepolymer uthintela ukugqobhoza kwethayile ngokwenza i-adhesive elastiki. Izincamathelisi ezinee-polymer powders ziyakwazi ukuguquguquka kwaye zinokufunxa uxinzelelo olunokufikelelwa kumgangatho nakwiindonga kwaye zinciphise amathuba okuqhekeka. Ukuthamba kwe-adhesive kuthetha ukuba iya kuhamba kunye nethayile, inciphise umngcipheko woxinzelelo olugqithisileyo kwithayile kwaye ithintele ukuba ithayile ingaphumi. Oku kuthetha ukuba i-adhesive inokugcwalisa izithuba, iindawo ezingenanto kunye nokungahambi kakuhle phakathi kwethayile kunye ne-substrate, iphucule umphezulu woqhagamshelwano phakathi kwezi zimbini.
Enye inzuzo yepowder yepolymer kukuba inamathela kakuhle kwiintlobo ezahlukeneyo zesubstrates, nto leyo ebalulekileyo ekuthinteleni ukugqobhoka kweethayile. Izincamathelisi ezinepowder yepolymer zinokunamathela kwizinto ezahlukeneyo, kuquka umthi, ikhonkrithi kunye nesinyithi. Ukukwazi ukunamathela kwiisubstrates ezahlukeneyo kunciphisa umngcipheko weethayile ezingenanto kwiindawo ezichaphazeleka kuxinzelelo, ukushukuma okanye ukungcangcazela. Izincamathelisi ezinepowder yepolymer ziqinisekisa ukuba iithayile ezinamathele kwisubstrate ziqinile ngokwesakhiwo kwaye ziyakwazi ukumelana noxinzelelo ngaphandle kokusuka kwisubstrate.
Iipowder zepolymer nazo zilula ukuzisebenzisa kwaye kulula ukuzisebenzisa, nto leyo eyenza zibe sisisombululo esifanelekileyo sokuthintela ukugqobhoza kweetayile. Le nto iza ngohlobo lwepowder kwaye ingaxutywa lula neeglu, nto leyo eyenza inkqubo yokufaka ikhawuleze kwaye ibe lula. Iiglu eziqulethe umgubo wepolymer ziqinisekisa ukuba iithayile zinamathela ngokulinganayo kwi-substrate, nto leyo enciphisa amathuba okuba iithayile zigqobhoze ngexesha lokufakwa.
Ukusetyenziswa kwepowders zepolymer kwi-adhesives zethayile kunokuthintela ukugoba kwethayile ngokuphucula iimpawu zokubopha zomaleko wokubopha. Umsebenzi wepowders zepolymer kukuphucula amandla okubopha kwe-adhesive kwi-substrate kunye neethayile ze-ceramic, okwenza i-bond eqinileyo phakathi kweetayile ze-ceramic kunye ne-substrate. Ikwadala i-adhesive elastiki efunxa uxinzelelo kunye nokuhamba, inciphisa umngcipheko wokuqhekeka kunye nokwahlukana kwi-substrate. Iimpawu zokugcina amanzi zepowders zepolymer nazo zandisa ixesha lokomisa, ukuqinisekisa ukuba i-adhesive ingangena kwi-tile kunye neendawo ze-substrate ukuze i-bond ibe ngcono. Okokugqibela, i-polymer powder ilula ukuyisebenzisa kwaye kulula ukuyisebenzisa kwaye inokubotshwa kwi-substrates ezahlukeneyo, okwenza ibe sisisombululo esifanelekileyo sokuthintela ukugoba kweetayile.
