Redispersible polymer powder (RDP) ninyongera yingirakamaro ya polymer ikoreshwa mugutezimbere imikorere ya sima, ishingiye kuri gypsumu, ishingiye kuri lime na lime-mortar. RDP itezimbere imikorere yuzuye yibi bikoresho binyuze mubikorwa byayo bihuza, gushimangira, kurwanya ibice, kurwanya amazi, nibindi, kandi ikoreshwa cyane mubikoresho byubaka.
Ubwoko bukuru bwa RDP
Ubwoko bwa RDP bushyirwa mubyiciro ukurikije ubwoko bwa substrate igizwe, umurima wo gusaba nibiranga imikorere. RDPs zisanzwe zirimo ibi bikurikira:
Ubwoko bwa Ethylene-vinyl acetate copolymer (EVA):
Ibiranga: Ethylene-vinyl acetate copolymer nimwe mubwoko bwa RDP. Ifite imiterere ihindagurika kandi ifatika, kandi itanga amazi meza yo guhangana n’ikirere.
Gushyira mu bikorwa: Ahanini bikoreshwa mu gufatisha tile, ibikoresho byo hasi-byo hasi, sisitemu yo gukingira urukuta hanze nizindi nzego.
Ibyiza: Itanga gukomera no guhinduka, bikwiranye nibihe bisaba guhinduka no gukomera.
Ibibi: Bitewe na Ethylene nyinshi, imikorere yayo irashobora kuba idahagije muri porogaramu zimwe na zimwe zisabwa imbaraga nyinshi.
Ubwoko bwa Ethylene-vinyl acetate-vinyl acetate terpolymer (VeoVa / EVA) ubwoko:
Ibiranga: Ubu bwoko bwa RDP butangiza VeoVa (vinyl ester) hashingiwe kuri Ethylene na vinyl acetate copolymerisation, iteza imbere amazi hamwe n’imiti ihamye yibikoresho.
Gushyira mu bikorwa: Bikunze gukoreshwa mu rukuta rwo hanze hamwe n'ibicuruzwa bya gypsumu, n'ibindi.
Ibyiza: Ifite amazi meza yo kurwanya no kurwanya imiti, ibereye hanze kandi ikoreshwa nabi.
Ibibi: Ugereranije n'ubwoko bwa EVA gakondo, igiciro gishobora kuba kinini.
Ubwoko bwa Styrene-butadiene (SB):
Ibiranga: Igizwe ahanini na styrene na butadiene monomers, kandi ifite imiterere myiza yo guhuza, guhinduka no kurwanya amazi.
Gushyira mu bikorwa: Bikunze gukoreshwa muri tile yometse hamwe na byoroshye.
Ibyiza: Guhuza neza no guhinduka, kandi nibikorwa byiza mukurwanya amazi.
Ibibi: Gicurasi imyaka munsi yumucyo ultraviolet.
Ubwoko bwa Vinyl acetate-Ethylene copolymer (VAE):
Ibiranga: Ni kopolymer ya vinyl acetate na Ethylene, hamwe nubworoherane bwiza no kurwanya amazi.
Gushyira mu bikorwa: Birakwiriye kumatafari ya tile, sisitemu yo gukingira urukuta rwo hanze, gypsumu ishingiye kurwego rwo hejuru, nibindi.
Ibyiza: Itanga gufata neza no kurwanya amazi, kandi ifite imiti irwanya imiti.
Ibibi: Igiciro ni kinini.
Ubwoko bwa Acrylic copolymer (Acrylic) ubwoko:
Ibiranga: Ibyingenzi byingenzi ni acrylic ester, ifite ubwuzuzanye bwiza kandi bworoshye.
Gushyira mu bikorwa: Irakoreshwa cyane muri marimari ishushanya, yometse kuri tile, gypsumu nibindi bikoresho.
Ibyiza: Guhuza neza no guhinduka, hamwe no kurwanya UV nziza.
Ibibi: Bitewe nigiciro kinini cyibikoresho bya acrylic, igiciro cyubu bwoko bwa RDP nacyo kiri hejuru.
Imikorere nibisabwa bya RDP
Kunoza imikorere yo guhuza:
RDP igira uruhare runini mubikoresho, yongerera imbaraga zifatika, kandi inoze guhuza ibikoresho byubaka na substrate.
Ahantu ho gusaba harimo gufatira tile, guhuza minisiteri, nibindi.
Kongera imbaraga zo guhangana no guhangana: Mugushyiramo RDP, ubworoherane bwibikoresho byateye imbere cyane, bifasha kwirinda ko habaho gucika.
Bikunze gukoreshwa muri sisitemu yo kubika, gushira byoroshye, ibikoresho byo gusana, nibindi.
Kunoza kurwanya amazi no kurwanya amazi:
RDP itezimbere amazi arwanya ibikoresho, ikabasha gukomeza gukora neza mubidukikije.
Bikoreshwa mubitambambuga bitarimo amazi, inkuta zo hanze, nibindi.
Kunoza imikorere yubwubatsi:
RDP irashobora kunoza imikorere yubwubatsi bwibikoresho byifu yumye, bigatuma kubaka byoroha kandi neza.
Byakoreshejwe cyane mubikoresho byo kuringaniza hasi, gutwikira, nibindi.
Kunoza igihe kirekire no guhangana nikirere: Bitewe no kongeramo RDP, kuramba no guhangana nikirere cyibikoresho byateye imbere cyane, kandi birashobora kwihanganira ikizamini cyibidukikije.
Bikoreshwa kuri sisitemu yo hanze, gutwikira igisenge, nibindi.
Ibitekerezo byo guhitamo RDP ibereye
Ibisabwa:
Hitamo ubwoko bwa RDP bukwiranye nuburyo bwihariye bwo gusaba, kurugero, porogaramu zo hanze zisaba RDP hamwe nikirere cyiza.
Kugenzura ibiciro:
Hashingiwe ku kwemeza imikorere, birakenewe gusuzuma ikiguzi cyibikoresho no guhitamo RDP yubukungu.
Guhuza:
RDP igomba guhuza neza nibindi bikoresho kugirango hamenyekane ituze hamwe nibikorwa bihoraho bivanze.
Ibisabwa mu mikorere:
Hitamo ubwoko bwa RDP ukurikije imitungo isabwa (nko guhinduka, gufatira hamwe, kurwanya amazi, nibindi).
Ifu ya redispersible latex igira uruhare runini mubikoresho byubwubatsi bugezweho, kandi ubwoko bwayo butandukanye butanga ibisubizo byoroshye kubikenerwa bitandukanye. Guhitamo ubwoko bwa RDP bukwiye birashobora kunoza cyane imikorere yibikoresho byubaka, bityo bikazamura ubwiza nigihe kirekire cyimishinga yubwubatsi.
