Redispersible polymer powder nimwe mubikoresho bisanzwe bikoreshwa mubwubatsi nizindi nganda. Ubwinshi bwayo, imikorere nubukungu bituma ihitamo gukundwa kubikorwa byinshi. Ariko, hamwe namahitamo menshi yo guhitamo, birashobora kuba ingorabahizi kubakoresha kumenya no guhitamo ibicuruzwa byiza kubyo bakeneye. Muri iyi ngingo, turaganira ku bintu by'ingenzi tugomba gusuzuma mbere yo guhitamo ifu ya polymer idasubirwaho.
1. Gusobanukirwa Ifu ya Polymer isubirwamo
Ifu ya polymer isubirwamo ni ifu yumye iboneka mugutera imiti itandukanye ya polymer mumashanyarazi ihindagurika hanyuma ikuma mugihe cyihariye. Ifu ya polymer isubirwamo igizwe ahanini nibikoresho bya polymer, binder reaction, plasitike hamwe nuwuzuza ibintu. Ikoreshwa cyane cyane nka binder, firime yahoze kandi ikabyimbye mubikorwa bitandukanye nka sima na gypsumu ishingiye kubikoresho, sisitemu yo kwirinda amazi na minisiteri.
2. Ibigize ifu ya polymer isubirwamo
Icyibanze, ibigize ifu ya polymer isubirwamo ni ikintu cyingenzi kigira ingaruka kumiterere yifu kandi ikwiranye nibisabwa. Kubwibyo, imiti ya polymer igomba gutekerezwa mbere yo guhitamo ibicuruzwa. Polimeri nyinshi zisubirwamo zishingiye kuri Ethylene vinyl acetate (EVA) na vinyl acetate Ethylene (VAE), ifite imiterere ninyungu zitandukanye.
EVA isubirwamo polymers iroroshye guhinduka, ikongera ubworoherane bwibicuruzwa byanyuma, kandi igatanga neza kandi ikanarwanya ikirere. Kurundi ruhande, VAE isubirwamo polymers ifite imbaraga nyinshi kandi irwanya amazi neza kuruta polymers ya EVA, bigatuma ikoreshwa mubisabwa hanze. Polimeri ya Acrylic ifite urwego rwohejuru rwo gufatana no guhuza nibindi bikoresho byubaka.
3. Imiterere yumubiri yifu ya polymer isubirwamo
Imiterere yumubiri ya polymer isubirwamo igomba kumvikana neza mbere yo guhitamo ibikenewe. Iyi miterere irimo ingano yubunini bwagabanijwe, gloss, ibara nubucucike bwinshi bwifu. Ibiranga bigira ingaruka kumikorere, gutunganya no kugaragara kubicuruzwa byanyuma.
Ingano yubunini bwo gukwirakwiza ifu ya polymer isubirwamo ningirakamaro kuko igena igipimo cyayo cyo gutandukana muri substrate. Kugenzura neza ingano yingingo mugihe cyo gukora ningirakamaro kugirango hamenyekane ifu yumubiri. Ubwinshi bwifu yifu bugira ingaruka kububiko bwayo, gutwara no gufata neza.
4. Ikoreshwa rya tekinoroji
Uburyo bwo gutoranya ifu ya polymer isubirwamo igomba kuzirikana tekinoroji igenewe. Buri bwoko bwisubiramo bwa polymer yifu ifite imiterere itandukanye ituma ifu imwe ikwiranye nubuhanga bwihariye bwo gukoresha kurusha ubundi. Kurugero, ifu-ya-viscosity ifu ikwiranye neza na progaramu ya spray, mugihe ifu-yuzuye-ifu irashobora gukenera intoki.
5. Guhuza ifu ya polymer isubirwamo nibindi bikoresho
Guhuza ni ikintu cyingenzi muguhitamo ifu ya polymer ikwiye. Mbere yo guhitamo ifu yihariye, nibyingenzi gusuzuma niba ihuza nibindi bikoresho bikoreshwa mubicuruzwa byanyuma, kurugero, ifu yatoranijwe igomba guhuza hamwe na sima hamwe nibindi bihuza.
6. Ibisabwa
Ibintu byifuzwa byibicuruzwa byanyuma bigena guhitamo ifu ya polymer ikwiye. Birakenewe kwerekana imiterere yumubiri na chimique yifu ya polymer isubirwamo, harimo impagarara zintera, pH, ubushyuhe bwikirahure, hamwe na modulus ya elastique.
Kumenya no gutoranya ifu ya polymer isubirwamo ni inzira ikomeye igomba gusuzuma ifu yimiti, imiterere yumubiri, tekinoroji yo gukoresha, guhuza hamwe nibisabwa. Ibintu bigomba gusuzumwa harimo ingano yubunini bwagabanijwe, ubwinshi bwinshi nuburabyo. Hanyuma, ni ngombwa kumenya imitungo ikwiranye nogushaka gukoreshwa, nka elastique, kurwanya ikirere, no guhuza nibindi bikoresho byubwubatsi. Urebye ibyo bintu, abakoresha barashobora guhitamo ifu ya polymer isubirwamo yujuje ibyo basabwa, itanga imikorere myiza, kandi ishyigikira intego zabo muri rusange.
