Impuphu ye-latex ephinde ichitheke iyimpuphu ye-polymer engaphinde ichitheke emanzini. Ivame ukusetshenziswa njengesithasiselo ezintweni zokwakha ezifana nezimbotshana, izinamathiseli zethayela kanye nama-grout. Impuphu ye-latex ephinde ichitheke isebenza njengesihlanganisi, inikeza ukunamathela okuhle kakhulu futhi ithuthukise izakhiwo zomkhiqizo wokugcina. Lesi sihloko sizogxila endleleni ukusetshenziswa kwempuphu ye-polymer ephinde ichitheke ngayo kungathuthukisa ngayo umthelela kanye nokumelana nokuguguleka kwe-mortar.
Ukumelana nomthelela
Ukumelana nokushayisana kuyisilinganiso sekhono lento yokumela ukushayisana okungazelelwe ngaphandle kokuqhekeka noma ukuqhekeka. Ku-mortar, ukumelana nokushayisana kuyisici esibalulekile, ngoba izobhekana nokushayisana okuhlukahlukene ngesikhathi sokwakhiwa nokusetshenziswa. I-mortar idinga ukuqina ngokwanele ukuze imelane nokushayisana ngaphandle kokuqhekeka futhi ibeke engcupheni ubuqotho besakhiwo noma indawo.
Izimpushana ze-polymer eziphinde zichithwe zithuthukisa ukumelana nokushayisana kwezingcezu ze-mortar ngezindlela eziningana. Okokuqala, kuthuthukisa ukuhlangana kwe-mortar. Uma zengezwa ku-mortar, izinhlayiya ze-polymer eziphinde zichithwe zisatshalaliswa ngokulinganayo kuyo yonke ingxube, zakha isibopho esiqinile kodwa esiguquguqukayo phakathi kwezinhlayiya zesihlabathi nesimende. Lokhu kuqinisa ukuhlangana kwe-mortar, okwenza imelane kakhulu nokuqhekeka nokuphuka lapho ishaywa.
I-matrix kamothara oqiniswe ngempuphu ye-latex ephinde ihlakazeke. Izinhlayiya ze-polymer eziku-mpuphu zisebenza njengamabhuloho phakathi kwama-aggregates, zigcwalisa izikhala futhi zidale isibopho esiqinile phakathi kwezinhlayiya zesihlabathi nesimende. Lokhu kuqinisa kunikeza ukumelana okwengeziwe kokushayisana, kuvimbela ukuthuthukiswa kwemifantu nokuqhekeka.
Impuphu ye-latex ephinde ihlakazeke ithuthukisa ukuguquguquka kanye nokunwebeka kwe-mortar. Izinhlayiya ze-polymer eziku-powder zithuthukisa ikhono le-mortar lokwelula nokugoba, zimunce amandla okushaya ngaphandle kokuqhekeka. Lokhu kuvumela i-mortar ukuba iguquke kancane ngaphansi kwengcindezi, kunciphisa amathuba okwakheka kwemifantu.
ukumelana nokuguguleka
Ukumelana nokuguguleka kungenye imfanelo ebalulekile yesimende. Isimende sivame ukusetshenziswa njengento engaphezulu, kungaba njengesiphetho esiveziwe noma njengesivikelo sezinye iziphetho ezifana nethayela noma itshe. Kulezi zimo, isimende sidinga ukuqina futhi simelane nokuguguleka, ukuguguleka kanye nokuguguleka.
Impuphu ye-polymer ephinde ihlakazeke ingathuthukisa nokumelana nokuguguleka kwe-mortar ngezindlela eziningana. Okokuqala, kusiza ekunciphiseni ukuguguleka kwe-mortar. Ukuguguleka kuyinkinga evamile ngezinto ezisekelwe kusimende, okubangela ukuqhekeka nokuguguleka kancane kancane kobuso. Ukwengezwa kwempuphu ye-polymer ephinde ihlakazeke kunciphisa inani lokuguguleka, okuqinisekisa ukuthi i-mortar igcina ubuqotho bayo besakhiwo futhi ihlala imelana nokuguguleka.
Impuphu ye-latex ephinde ihlakazeke ithuthukisa ukunamathela kwe-mortar ku-substrate. Izinhlayiya ze-polymer ku-powder zakha isibopho esiqinile ne-substrate, zivimbela i-mortar ukuthi iphakanyiswe noma iwele ebusweni lapho ihlukunyezwa. Lokhu kwandisa ukuqina kwe-mortar, okuqinisekisa ukuthi inamathela ngokuqinile ku-substrate futhi imelana nokuguguleka.
Impuphu ye-latex ephinde ihlakazeke ikhulisa ukuguquguquka nokuqina kwe-mortar. Njengokumelana nokushayisana, ukuguquguquka nokuqina kwe-mortar kudlala indima ebalulekile ekumelaneni nokuguguleka. Izinhlayiya ze-polymer ku-powder zandisa ikhono le-mortar lokuguquguquka ngaphansi kwengcindezi futhi zimunce amandla okuguguleka ngaphandle kokuqhekeka noma ukuqhekeka.
Impuphu ye-polymer ephinde ihlakazeke iyisithako esisebenza ngezindlela eziningi esingathuthukisa ukusebenza kwe-mortar. Ithuthukisa ukuhlangana, ukuqinisa, ukuguquguquka kanye nokunwebeka kwe-mortar, okwenza kube ithuluzi elibalulekile lokuthuthukisa ukumelana nokushaqeka kanye nokuguguleka.
Ngokusebenzisa i-polymer powder ehlakazekayo odakeni lwabo, abakhi kanye nabakhi bangaqinisekisa ukuthi izakhiwo zabo ziqinile, zihlala isikhathi eside futhi azikwazi ukuguguleka. Lokhu kwandisa isikhathi eside sesakhiwo, kunciphisa izindleko zokulungisa futhi kuthuthukise ukuphepha okuphelele.
Sekukonke, ukusetshenziswa kwezimpushana ze-polymer ezihlakazekayo kuyintuthuko enhle embonini yokwakha, okuhlinzeka ngendlela ephumelelayo nengabizi yokuthuthukisa ukusebenza kwezimbobo nokuqinisekisa izakhiwo eziqinile.
