Ibyiciro bya Redispersible Polymer Powder (RDP)

Redispersible Polymer Powder (RDP) nubwoko bwifu ya copolymer ikoreshwa cyane mubikorwa bitandukanye byubwubatsi.RDPs ikorwa nuburyo bwitwa spray drying.Muri iki gikorwa, imvange ya monomers-soluble monomers nibindi byongerwaho emulisiyasi, hanyuma amazi akurwaho binyuze mukumisha spray.Ibicuruzwa bivamo ni ifu ishobora guhindurwa byoroshye mumazi.RDPs ifata neza, ihindagurika, hamwe n’amazi arwanya amazi, bigatuma biba byiza gukoreshwa mubisabwa byinshi.

Itondekanya rya RDPs rishingiye ku bintu byinshi, birimo imiterere yimiti, inzira ya polymerisation, nibintu byanyuma byibicuruzwa.Muri iki kiganiro, tuzaganira ku byiciro bya RDPs dushingiye ku miterere yabyo.

Vinyl Acetate Ethylene (VAE) RDPs

VAE RDPs nubwoko bukoreshwa cyane bwa RDPs.Byakozwe na copolymerizing vinyl acetate (VA) na Ethylene (E) imbere yabandi ba monomers nka acrylate cyangwa methacrylate.Ibirimo VA muri copolymer biratandukanye hagati ya 30% na 80%, bitewe nibisabwa.VAE RDPs izwiho ibyiza byo gufatira hamwe, guhinduka, no kurwanya amazi.Bikunze gukoreshwa mumatafari, amakoti yikariso, hamwe nudukuta.

RDPs

RDP ya Acrylic ikorwa na copolymerizing estry acrylic hamwe nabandi ba monomers nka vinyl acetate, Ethylene, cyangwa styrene.Estrice ya acrylic ikoreshwa muri copolymer irashobora kuba methyl methacrylate (MMA), butyl acrylate (BA), cyangwa guhuza byombi.Imiterere ya acrylic RDPs iterwa nikigereranyo cya monomers ikoreshwa mugikorwa cya copolymerisation.RDPs ya Acrylic ifite imbaraga zo guhangana nikirere cyiza, kandi zikunze gukoreshwa muburyo bwo hanze, ibyuma bitarinda amazi, hamwe na cimaitima.

Styrene Butadiene (SB) RDPs

SB RDPs ikorwa na copolymerizing styrene na butadiene imbere yabandi ba monomer nka acrylate cyangwa methacrylate.Ibiri muri styrene muri copolymer biratandukanye hagati ya 20% na 50%, bitewe nibisabwa.SB RDPs ifite ibintu byiza bifata neza, kandi bikoreshwa mubisanzwe bifata amatafari, minisiteri, na grout.

Vinyl Acetate (VA) RDPs

VA RDPs ikorwa na homopolymerizing vinyl acetate monomers.Bafite vinyl acetate nyinshi, kuva kuri 90% kugeza 100%.VA RDPs ifite ibintu byiza bifata neza, kandi bikoreshwa mubisanzwe bifata amatafari, ibikoresho bihuza, hamwe na sima.

Ethylene Vinyl Chloride (EVC) RDPs

EVC RDPs ikorwa na copolymerizing Ethylene na vinyl chloride imbere yabandi ba monomers nka acrylate cyangwa methacrylate.Vinyl chloride yibirimo muri copolymer iratandukanye hagati ya 5% na 30%, bitewe nibisabwa.EVC RDPs irwanya amazi meza kandi ifatanye neza na substrate zitandukanye.Bikunze gukoreshwa mumatafari, amakoti yikariso, hamwe nudukuta.

Mugusoza, RDPs nubwoko bwingenzi bwifu ya copolymer ikoreshwa cyane mubikorwa bitandukanye byubwubatsi.Itondekanya rya RDPs rishingiye ku bintu byinshi, birimo imiterere yimiti, inzira ya polymerisation, nibintu byanyuma byibicuruzwa.Imiterere yimiti ya RDPs irashobora gushyirwa mubice bya Vinyl Acetate Ethylene (VAE) RDPs, Acrylic RDPs, Styrene Butadiene (SB) RDPs, Vinyl Acetate (VA) RDPs, na Ethylene Vinyl Chloride (EVC) RDPs.Buri bwoko bwa RDP bufite imiterere yihariye ituma ibera porogaramu yihariye.

Ni ngombwa guhitamo ubwoko bukwiye bwa RDP kugirango porogaramu runaka igere kubisubizo byiza.Ibintu bigomba kwitabwaho muguhitamo RDP ikwiye harimo ubwoko bwa substrate, imbaraga zifatika zifatika, kurwanya amazi, guhinduka, no guhangana nikirere.

Byongeye kandi, RDPs irashobora guhuzwa nibindi bikoresho nka sima, umucanga, nibindi byongeweho kugirango habeho ibicuruzwa bikora neza cyane nka tile yometse kuri tile, grout, amakoti ya skim, hamwe nimpuzu zo hanze.Imiterere yibicuruzwa byanyuma irashobora kunozwa muguhindura ingano ya RDP yakoreshejwe nibindi bipimo.

Muncamake, RDPs nubwoko butandukanye bwifu ya copolymer itanga imbaraga zifatika zifatika, kurwanya amazi, no guhinduka.Zikoreshwa cyane mubikorwa bitandukanye byubwubatsi, harimo ibyuma bifata tile, amakoti ya skim, hamwe nimbere.Ibyiciro bya RDPs bishingiye kubigize imiti, birimo VAE RDPs, RDPs ya acrylic, SB RDPs, VA RDPs, na EVC RDPs.Nibyingenzi guhitamo RDP ikwiye kubisabwa kugirango ugere kubisubizo byiza.
