Impuphu ye-polymer iyinto efakwa ku-adhesive yethayela ukuvimbela ukugoba kwamathayela. Ukwengeza i-polymer powder engxubeni ye-adhesive kuthuthukisa amakhono okubopha kwe-adhesive, okudala isibopho esiqinile phakathi kwethayela ne-substrate. Amathayela angenalutho abonisa ukuntuleka kokuxhumana okwanele phakathi kwethayela ne-substrate, noma ukuntuleka kwe-adhesive phakathi kwezindawo ezimbili. Ekwakhiweni, ukugoba kwamathayela kuye kwabhekwa njengendaba ebalulekile okufanele ixazululwe. Impuphu ye-polymer iye yabonakala iphumelela ekuvimbeleni ukugoba kwamathayela nokuqinisekisa ukufakwa okuphephile. Lesi sihloko sixoxa ngendlela ama-polymer powder angavimbela ngayo ukugoba kwamathayela ekwakheni.
Ama-powder e-polymer avame ukwenziwa ngama-powder e-polymer aphinde ahlakazeke (RDP) futhi asetshenziswa kakhulu kuma-premixes, ama-mortar e-dry mix kanye nezifundo zokubopha. I-RDP iyi-powder equkethe ingxube ye-vinyl acetate ne-ethylene. Umsebenzi we-polymer powder ukuthuthukisa izakhiwo zokubopha zesendlalelo sokubopha, ukwandisa amandla okubopha amathayili e-ceramic kanye namandla okunamathela kwe-glue. Isendlalelo sokubopha siqukethe i-polymer powder enikeza ukunamathela okuhle kakhulu ezinhlotsheni ezahlukene ze-substrate kufaka phakathi ukhonkolo, ukhonkolo oqoshiwe kanye ne-plasterboard.
Impuphu ye-polymer isebenza futhi njenge-ejenti yokugcina amanzi, ithuthukisa ukugeleza okuphelele kwengxube ye-binder. Impuphu ye-polymer isiza ukugcina okuqukethwe komswakama ku-glue, ngaleyo ndlela yandise isikhathi sokomisa se-glue. Ngenxa yenqubo yokomisa ehamba kancane, i-glue ingangena ethayileni nasezindaweni ze-substrate, idale isibopho esiqinile. Ingxube ye-glue ejiyile, ebeka kancane isiza ukuvimbela ukugoba kwama-tile ngokuqinisekisa ukuthi amathayili afakwe ku-glue futhi ngeke aphume ngesikhathi sokufakwa.
Ngaphezu kwalokho, i-polymer powder ivimbela ukugoba kwethayela ngokudala ingcina enwebekayo. Izinti ezinamathelayo eziqukethe i-polymer powders ziyaguquguquka futhi zingamunca ukucindezeleka okungase kuzwakale phansi nasezindongeni futhi zinciphise amathuba okuqhekeka. Ukuqina kwe-glue kusho ukuthi izohamba nethayela, inciphise ingozi yokucindezela ngokweqile kuthayela futhi ivimbele ithayela ukuthi lingaphumi. Lokhu kusho nokuthi ingcina ingagcwalisa izikhala, izimbobo kanye nokungalingani phakathi kwethayela kanye ne-substrate, ithuthukise indawo yokuxhumana phakathi kwalezi zinto ezimbili.
Enye inzuzo yempuphu ye-polymer ukunamathela kwayo okuhle ezinhlotsheni ezahlukene ze-substrate, okubalulekile ukuvimbela ukugoba kwamathayela. Izinamathiseli eziqukethe iziphawuda ze-polymer zinganamathela ezintweni ezahlukahlukene, okuhlanganisa ukhuni, ukhonkolo kanye nensimbi. Amandla okunamathela eziphawudakeni ezahlukene anciphisa ingozi yamathayela angenalutho ezindaweni ezithinteka yingcindezi, ukunyakaza noma ukudlidliza. Izinamathiseli eziqukethe i-polymer powder ziqinisekisa ukuthi amathayela axhunywe ku-substrate aqinile ngokwesakhiwo futhi ayakwazi ukumelana nokucindezeleka ngaphandle kokusuka ku-substrate.
Ama-polymer powder nawo alula ukuwasebenzisa futhi kulula ukuwasebenzisa, okwenza abe yisisombululo esifanele sokuvimbela ukugoba kwethayela. Izinto ezisetshenziswayo zifika ngesimo sempuphu futhi zingaxutshwa kalula nezinamathiseli, okwenza inqubo yokufaka isheshe futhi ibe lula. Ama-adhesive aqukethe i-polymer powder aqinisekisa ukuthi amathayela anamathela ngokulinganayo ku-substrate, okunciphisa amathuba okugoba kwethayela ngesikhathi sokufakwa.
Ukusetshenziswa kwama-polymer powder kuma-adhesive e-tile kungavimbela ukugoba kwethayela ngokuthuthukisa izakhiwo zokubopha zesendlalelo sokubopha. Umsebenzi we-polymer powder ukuthuthukisa amandla okubopha kwe-adhesive ku-substrate kanye nama-ceramic tile, kwakha isibopho esiqinile phakathi kwama-ceramic tile kanye ne-substrate. Kuphinde kwakha i-adhesive enwebekayo emunca ukucindezeleka nokunyakaza, kunciphisa ingozi yokuqhekeka nokuhlukana ne-substrate. Izakhiwo zokugcina amanzi ze-polymer powder nazo zandisa isikhathi sokomisa, ziqinisekisa ukuthi i-adhesive ingangena ezindaweni ze-tile kanye ne-substrate ukuze i-bonding ibe ngcono. Okokugcina, i-polymer powder ilula ukuyisebenzisa futhi ilula ukuyisebenzisa futhi ingabopha kuma-substrate ahlukene, okwenza kube yisisombululo esifanele sokuvimbela ukugoba kwama-tile.
