Dab tsi yog cov ntau yam ntawm redispersible polymer hmoov?

Redispersible polymer hmoov (RPP) muaj nyob rau ntau yam ntau yam, txhua tus txiav rau cov ntawv thov tshwj xeeb thiab kev ua tau zoo. Qhov muaj pes tsawg leeg, cov khoom, thiab npaj siv ntawm RPP tuaj yeem sib txawv raws li cov khoom siv polymer, thiab cov txheej txheem kev tsim khoom. Ntawm no yog qee cov ntau yam ntawm recispersible polymer hmoov:

1. Hom Polymer:
   • Ethylene-Vinyl acetate (EVA) RPP: Eva-based RPP: Eva-based RPPs yog vile cov ntawv thov, mortars, thiab kev ntsuas tus kheej. Lawv muab kev hloov pauv tau zoo, kev ua yeeb yam, thiab dej tsis kam.
   • Vinyl acetate-ethylene (Vae) RPP: Vae-based RPP: Vae Lawv tsim nyog rau cov ntawv thov xws li pobzeb cov nplaum, hloov cov dej tsis muaj dej lim, thiab cov xov xwm.
   • Acrylic RPP: Acrylic-Raws RPPS muab Adhesion zoo dua, huab cua tsis kam, thiab kav ntev. Lawv feem ntau siv nyob rau sab nrauv sab nrauv thiab cov txheej txheem tiav (EIFS), waterproofing txheej, thiab kev ua haujlwm siab.
   • Styrene-Acrylic RPP: Styrene-Acrylic-Raws RPPs muaj kev sib npaug ntawm cov nplaum, hloov tau, thiab dej tsis kam. Lawv tsim nyog rau cov ntawv thov xws li Pobzeb Grouts, Foob Ciav, thiab cov ntawv tso nyiaj.
   • Cawv (PVA) RPP: PVA raws RPP: Pva raws RPPs muab siab siab, ua yeeb yaj kiab ua yeeb yam, thiab tiv taus alkalis. Lawv feem ntau yog siv nyob rau hauv cov xim tha xim sab hauv, textured tiav, thiab kho kom zoo nkauj plasters.
2. Muaj nuj nqi ntxiv ntxiv:
   • Cov hnab yas: Qee RPPs tuaj yeem muaj cov tshuab yas kom txhim kho kom tau yooj yim, kev ua haujlwm, thiab adhesion. Planized RPPs feem ntau siv hauv kev siv dej tsis tau zoo
   • Stabilizers: Stabilizers tau ntxiv rau RPP cov kev sib xyaw los txhim kho lub neej ua haujlwm, chaw tso khoom ruaj khov, thiab dispersibility. Lawv pab tiv thaiv kom agglomeration thiab kom ntseeg tau cov kev sib cais ntawm RPP hais hauv dej.
3. Particle loj thiab morphology:
   • RPPs muaj nyob rau hauv ntau lub particle thiab ntau thiab thiab cov morphologies kom tau raws li cov kev thov uas yuav tsum tau ua. Cov nplais zoo me me yuav muab cov yeeb yaj kiab zoo dua thiab nto smoothness, thaum cov ntxhib coarse yuav txhim kho dej khaws cia thiab cov khoom siv neeg kho mob.
4. Qib Tshwj Xeeb:
   • Qee cov tuam ntxhab muaj cov qib tshwj xeeb ntawm RPPs ua kom pom tseeb lossis cov yam ntxwv ua tau zoo. Cov no yuav suav nrog RPPs nrog cov dej ntws tawm, khov-yaj-muaj peev xwm, lossis tswj cov khoom tso tawm.
5. Kev Cai Tsim:
   • Ntxiv rau cov qauv ntau yam, cov qauv kev cai ntawm RPPs tuaj yeem tsim los ua kom tau los ua kom tau los ua kom tau los ua kom tau raws li cov neeg siv khoom tshwj xeeb lossis cov phiaj xwm. Kev cai RPP yuav teeb tsa tshwj xeeb cov polymers, ntxiv, lossis kev ua tau zoo hloov kho cov neeg siv khoom tshwj xeeb.

Ntau yam ntawm redispersible hmoov polymer muaj nyob rau hauv kev ua lag luam xav txog ntau yam kev xav tau ntawm kev txhim kho cov khoom lag luam, cov khoom siv ruaj khov, thiab ua haujlwm.
