Iyini impushana ehlakazeka kabusha?

I-Redispersible powder iyimpushana ye-polymer eklanyelwe ngokukhethekile ukuthuthukisa izakhiwo ze-cementitious noma i-gypsum-based materials, njengodaka, i-grout, noma ukhonkolo. Le powder yenziwa ngokufafaza ingxube ye-polymer emulsion nezinye izithasiselo ukwenza impushana egeleza mahhala engaphinde ihlakazwe kalula emanzini.

Lapho i-powder ehlakazeka kabusha ingeziwe ekuxubeni okomile, yakha ifilimu ebusweni bezinhlayiya zikasimende ezithuthukisa ukunamathela, ukumelana kwamanzi, ukuguquguquka, nokusebenza. Ifilimu ye-polymer iphinde ivimbele izinhlayiya zikasimende ekuhlanganeni, okunciphisa ingozi yokuqhekeka, ukuncipha, noma ukuwohloka komkhiqizo wokugcina.

Izimpushana ezihlakazeka kabusha zivame ukusetshenziswa ezinhlelweni zokwakha ukuze kuthuthukiswe ukusebenza kwemikhiqizo esekwe usimende noma ye-gypsum, ikakhulukazi ezinhlelweni zokusebenza ezisebenza kahle lapho kudingeka khona ukuqina, amandla, nokuguquguquka. Zibuye zisetshenziselwe ukuthuthukisa ukungaguquguquki nokusebenza kwezingxube ezomile, okwenza kube lula ukuphatha, ukusabalala, nokuqeda.
