Redispersible polymer powder (RDP) ni polymer ikoreshwa nkinyongeramusaruro yumye.RDP ni ifu ikorwa na spray yumisha polymer emuliyoni.Iyo RDP yongewe kumazi ikora emulisiyo ihamye ishobora gukoreshwa mugukora minisiteri.RDP ifite imitungo myinshi ituma yongerwaho agaciro mumashanyarazi yumye.Iyi mitungo irimo:
Kubika amazi: RDP ifasha kugumana amazi muri minisiteri, bityo igateza imbere imikorere ya minisiteri no kugabanya amazi asabwa.
Adhesion: RDP irashobora kunoza guhuza hagati ya minisiteri na substrate, bityo bikazamura imbaraga nigihe kirekire cya minisiteri.
Imikorere: RDP irashobora kuzamura ireme ryibicuruzwa byarangiye byorohereza minisiteri gutunganya.
Kuramba: RDP irashobora kongera uburebure bwa minisiteri, bigatuma irwanya gucika nikirere.
RDP ninyongera yimikorere myinshi ishobora gukoreshwa mumashanyarazi atandukanye yumye.Irakwiriye cyane cyane ya minisiteri ikoreshwa mubikorwa byo hanze nka stucco hamwe na tile.RDP irashobora kandi gukoreshwa muri minisiteri ikoreshwa mubikorwa byimbere nko kuzuza hamwe no gusana ibice.
Dore inyungu zimwe zo gukoresha RDP mumashanyarazi yumye:
Kunoza gufata neza amazi
Kunoza gukomera
Kunoza imikorere
byongerewe igihe kirekire
gabanya gucamo
kugabanya kwangiza amazi
ongera guhinduka
Kunoza guhangana nikirere
RDP ninyongera yizewe kandi yingirakamaro ishobora gukoreshwa mugutezimbere imikorere yumuti wumye.Nigikoresho ntagereranywa kubasezeranye nabubatsi bashaka gukora minisiteri iramba, yujuje ubuziranenge.
Dore bumwe mu bwoko bwa RDP bukoreshwa muri minisiteri yumye:
Vinyl Acetate Ethylene (VAE): VAE RDP nubwoko busanzwe bwa RDP.Nuburyo butandukanye kandi buhendutse bushobora gukoreshwa muri minisiteri zitandukanye.
Styrene Butadiene Acrylate (SBR): SBR RDP ni amahitamo ahenze kuruta VAE RDP, ariko itanga gufata neza amazi no kuyifata.
Polyurethane (PU): PU RDP nubwoko buhenze bwa RDP, ariko ifite uburyo bwiza bwo gufata amazi, gufatana no kuramba.
