I-polymer redispersible powder RDP ingaphinde ihlakazwe ngokushesha ibe yi-emulsion ngemva kokuxhumana namanzi, futhi inezakhiwo ezifanayo njenge-emulsion yokuqala, okungukuthi, ifilimu ingakhiwa ngemva kokuba amanzi eqhuma. Le filimu inokuguquguquka okuphezulu, ukumelana nesimo sezulu esiphezulu kanye nokumelana nokunamathela okuhlukahlukene Okuphezulu kuma-substrates ahlukahlukene. Ngaphezu kwalokho, i-latex powder ene-hydrophobicity ingenza udaka lube nokuphikiswa okuhle kwamanzi.
I-polymer powder e-redispersible isetshenziswa kakhulu ku:
Impushana ye-putty yodonga lwangaphakathi nangaphandle, okokunamathelisa kuthayela, igrout yethayela, i-ejenti yesixhumi esibonakalayo sempushana eyomile, udaka lwangaphandle oluvala ukushisa okushisayo, udaka oluzilinganisa ngokwalo, udaka lokulungisa, udaka lokuhlobisa, udaka olungangeni manzi nodaka lwangaphandle olushisayo oluxutshwe okomile. Odakeni, okokuthuthukisa ubuthakathaka bodaka lukasimende lwendabuko olufana nokuba brittleness kanye ne-high elastic modulus, kanye nokunikeza udaka lukasimende ukuguquguquka okungcono namandla ebhondi eqinile ukumelana nokubambezeleka kokuqhekeka kodaka lukasimende. Njengoba i-polymer kanye nodaka lwakha isakhiwo senethiwekhi esingena ngaphakathi, ifilimu ye-polymer eqhubekayo yenziwa ezimbotsheni, eqinisa isibopho phakathi kwama-aggregates futhi ivimbe ezinye ze-pores ku-mortar. Ngakho-ke, udaka olushintshiwe ngemva kokuqina lunokusebenza okungcono kunodaka lukasimende. Intuthuko enkulu.
Indima ye-polymer powder ehlakazeka kabusha odakeni ikakhulukazi kulezi zici ezilandelayo:
1 Thuthukisa amandla okucindezela kanye namandla aguqukayo odaka.
I-2 Ukwengezwa kwe-latex powder kwandisa ukunwetshwa kodaka, ngaleyo ndlela kuthuthukisa ukuqina komthelela wodaka, futhi ngesikhathi esifanayo kunikeza udaka umphumela omuhle wokuhlakazeka kokucindezeleka.
3 Thuthukisa izakhiwo zokubopha zodaka. Indlela yokubopha incike ekukhangisweni nasekusakazeni kwama-macromolecules endaweni enamathelayo. Ngesikhathi esifanayo, i-powder yenjoloba inokungena okuthile futhi ingena ngokugcwele ebusweni bezinto eziyisisekelo kanye ne-cellulose ether, ukuze izakhiwo ezingaphezulu zesendlalelo sesisekelo kanye ne-plaster entsha ziseduze, ngaleyo ndlela kuthuthukisa ukusebenza kwesisekelo. . I-Adsorption, ukusebenza kwayo kwanda kakhulu.
4 Nciphisa i-elastic modulus yodaka, uthuthukise ikhono lokuguquguquka, futhi unciphise isenzakalo sokuqhekeka.
5 Thuthukisa ukumelana nokuhuzuka kodaka. Ukuthuthukiswa kokumelana nokugqokwa kubangelwa ikakhulukazi ukuba khona kwenani elithile lama-rubber ridges ebusweni bodaka, i-powder yerabha idlala indima yokubopha, futhi isakhiwo se-mesh esakhiwe yi-powder yerabha singadlula emigodini kanye nemifantu. udaka lukasimende. Ithuthukisa ukunamathela kwe-binder kumkhiqizo we-cement hydration, ngaleyo ndlela ikhulise ukumelana nokugqoka.
6 Nikeza udaka ukumelana okuhle kakhulu kwe-alkali.
7 Thuthukisa ukuhlangana kwe-putty, ukumelana okuhle kakhulu, ukumelana ne-alkali, ukumelana nemihuzuko, futhi uthuthukise amandla okuguquguquka.
8. Thuthukisa ukungangeni kwamanzi kanye nokungena kwe-putty.
9 Thuthukisa ukugcinwa kwamanzi kwe-putty, wandise isikhathi esivulekile, futhi uthuthukise ukusebenza.
10 Thuthukisa ukumelana komthelela we-putty futhi uthuthukise ukuqina kwe-putty.
I-latex powder e-redispersible yenziwe nge-polymer emulsion ngokumisa isifutho. Ngemuva kokuxubana namanzi odakeni, i-emulsified futhi ihlakazwe emanzini ukuze yakhe i-emulsion ye-polymer ezinzile. Ngemuva kokuthi i-latex powder ehlakazeka kabusha ifakwe emulsified futhi ihlakazwe emanzini, amanzi ayahwamuka. Ifilimu ye-polymer yakhiwe odakeni ukuze kuthuthukiswe izakhiwo zodaka. Izimpushana ze-polymer ezihlakazeka kabusha ezihlukene zinemiphumela ehlukene kudaka olomile lwempushana.
