Redispersible polymer powder (RDP) nuruvange rwimvange rwa polymers ninyongeramusaruro zikoreshwa cyane mubikoresho byubwubatsi, cyane cyane mukubyara amavuta avanze.Iyi poro igira uruhare runini mugutezimbere imikorere nibiranga ibikoresho bitandukanye byubwubatsi nka tile yometse kuri tile, grout, ibinganiza ubwayo hamwe na plaque ya sima.
Ibyingenzi byingenzi:
Polimeri shingiro:
Ethylene vinyl acetate (EVA): EVA copolymer ikunze gukoreshwa muri RDP bitewe nuburyo bwiza bwo gukora firime, guhuza, no guhinduka.Vinyl acetate yibirimo muri copolymer irashobora guhinduka kugirango ihindure imiterere ya polymer.
Vinyl Acetate na Carbone ya Ethylene: Ukurikije ibisabwa byihariye bisabwa, abayikora barashobora gukoresha karubone ya Ethylene aho gukoresha vinyl acetate.Caribone ya Ethylene yateje imbere kurwanya amazi no kuyifata neza.
Acrylics: Polimeri ya Acrylic, harimo na acrylics cyangwa copolymer yera, ikoreshwa muburyo budasanzwe bwo guhangana nikirere, kuramba, no guhuza byinshi.Bazwiho gutanga neza cyane kubutaka butandukanye.
Kurinda colloid:
Hydroxypropyl methylcellulose (HPMC): HPMC ni colloid ikingira ikunze gukoreshwa muri RDP.Itezimbere ibice bya polymer kandi ikazamura muri rusange ifu.
Inzoga ya polyvinyl (PVA): PVA nubundi buryo bwo gukingira bufasha mu gutuza no gukwirakwiza uduce duto twa polymer.Ifite kandi uruhare mukugenzura ububobere bwifu.
Amashanyarazi:
Dibutyl Phthalate (DBP): DBP ni urugero rwa plasitike ikunze kongerwa muri RDP kugirango irusheho guhinduka no gutunganya.Ifasha kugabanya ubushyuhe bwikirahure cya polymer, bigatuma birushaho kuba byiza.
uwuzuza:
Kalisiyumu Carbone: Iyuzuza nka karubone ya calcium irashobora kongerwamo kugirango yongere igice kinini cyifu kandi itange uburyo buhendutse bwo guhindura imitungo nkimiterere, ububobere nubusa.
Stabilisateur na antioxydants:
Stabilisateur: Ibi bikoreshwa mukurinda kwangirika kwa polymer mugihe cyo kubika no gutunganya.
Antioxydants: Antioxydants irinda polymer kwangirika kwa okiside, bigatuma RDP iramba.
Imikorere ya buri kintu:
Polymer base: Itanga ibintu byerekana firime, gufatana, guhinduka hamwe nimbaraga za mashini kubicuruzwa byanyuma.
Kurinda colloid: Kongera kugarurwa, gutuza no gukwirakwiza ibice bya polymer.
Plastiseri: Itezimbere guhinduka no gutunganywa.
Uzuza: Hindura imitungo nkimiterere, porosity, na opacity.
Stabilisateur na antioxydants: Irinde kwangirika kwa polymer mugihe cyo kubika no gutunganya.
mu gusoza:
Redispersible polymer powder (RDP) nibintu byinshi kandi byingenzi mubikoresho byubaka bigezweho.Ibigize imiti, harimo polymers nka EVA cyangwa resin ya acrylic, colloide ikingira, plasitike, ibyuzuza, stabilisateur na antioxydants, byateguwe neza kugirango byuzuze ibisabwa byihariye bya buri porogaramu.Ihuriro ryibi bice bifasha kunoza ifu isubirwamo, imbaraga zumubano, guhinduka no gukora muri rusange mumashanyarazi yumye.
