I-Redispersible Polymer Powder(RDP)iyisengezo esibalulekile esisetshenziswa ekwenziweni okuhlukahlukene kodaka olomile. I-polymer-based powder okuthi, uma ihlanganiswe namanzi, iphinde isabalalise ukwenza ifilimu. Le filimu idlulisela izici ezimbalwa ezibalulekile odakeni, njengokunamathela okuthuthukisiwe, ukuguquguquka, ukumelana namanzi, nokumelana nokuqhekeka. Njengoba izidingo zokwakha zishintsha, ama-RDP athole ukusetshenziswa okubanzi emikhiqizweni ekhethekile yodaka olomile, lapho izinzuzo zabo zidlala indima ebalulekile ekuthuthukiseni izici zokusebenza.
1.I-Redispersible Polymer Powder(RDP) Uhlolojikelele
I-Redispersible Polymer Powder(RDP)s ikhiqizwa ngokomisa ama-emulsions ama-polymers okwenziwa, ngokuvamile i-styrene-butadiene (SB), i-vinyl acetate-ethylene (VAE), noma ama-acrylics. Lawa ma-polymers agaywe kahle futhi anekhono lokuphinde ahlakazeke lapho exutshwe namanzi, enze ifilimu ethuthukisa izici zemishini zodaka.
Izici ezibalulekile zama-RDPs:
Ukuthuthukiswa kokunamathela: Ithuthukisa ukubopha kuma-substrates.
Ukuvumelana nezimo: Ihlinzeka ngendawo yokuhlala yokunyakaza futhi inciphisa ukuqhekeka.
Ukumelana namanzi: Kwenyusa ukumelana nokungena kwamanzi.
