Dab tsi yog redispersible polymer hmoov?

Redispersible polymer hmoov (RPP) yog dawb-hmoov ua rau los ntawm tshuaj tsuag-kom qhuav polymer dispersions lossis emulsions. Lawv muaj cov polymer hais tias yog coated nrog cov neeg sawv cev tiv thaiv thiab ntxiv. Thaum sib xyaw nrog dej, cov hmoov no tau yooj yim dua los tsim cov polymer ruaj khov, ua rau lawv cov xim pleev xim rau hauv kev tsim kho, pleev xim, cov nplaum, thiab lwm yam khoom lag luam.

Composition:

Cov muaj pes tsawg leeg ntawm cov hmoov nplej polymer polymer feem ntau suav nrog cov hauv qab no:

1. Polymer hais: Thawj cov thawj ntawm RPP yog polymer hais, uas ethylene-vinyl acetate (styrene-butadiene (sb), lossis polyvinyl acetate ( PVA). Cov polymers no pab txhawb rau cov khoom xav tau thiab kev ua tau zoo ntawm cov khoom kawg.
2. Cov neeg sawv cev tiv thaiv: Txhawm rau tiv thaiv cov polymer hais los ntawm agglomerating thaum lub sijhawm khaws khoom thiab kev thauj mus los, cov neeg tiv thaiv kab mob polyvinyl feem ntau siv. Cov neeg sawv cev no tswj cov polymer hais thiab ua kom lawv recispersibility hauv dej.
3. Cov yas tshuab: cov planizers yuav raug ntxiv rau txhim kho kom tau yooj yim, kev ua haujlwm, thiab cov nplaum ntawm RPPs. Cov tshuaj ntxiv no pab kom ua kom zoo dua ntawm cov polymer hais hauv ntau cov ntawv thov, tshwj xeeb hauv cov txheej txheem yooj yim, cov nplaum, thiab cov seev cev.
4. Fitters thiab Ntxiv: Ua raws li cov kev cai thov tshwj xeeb, sau, cov pigments, txo cov khoom sib txawv, thiab lwm yam kev ua haujlwm lossis muab cov haujlwm tshwj xeeb.

Cov khoom thiab cov yam ntxwv:

Recispersible polymer hmoov nthuav tawm ob peb lub peev xwm tseem ceeb thiab cov yam ntxwv uas ua rau lawv muaj ntau yam thiab siv ntau yam lag luam:

1. Recispersibility: RPP tau yooj yim tawg hauv dej los ua cov polymer ruaj khov lossis tawg, tso cai rau kev ua kom haum rau cov qauv thiab cov ntawv thov txuas ntxiv.
2. Zaj duab xis-tsim muaj peev xwm: thaum dispersed hauv dej thiab thov mus rau hauv thaj chaw, RPP tuaj yeem ua cov yeeb yaj kiab nyias nyias, txuas ntxiv cov yeeb yaj kiab, txuas ntxiv cov yeeb yaj kiab, txuas ntxiv cov yeeb yaj kiab, txuas ntxiv cov yeeb yaj kiab, txuas ntxiv cov yeeb yaj kiab, txuas ntxiv cov yeeb yaj kiab, txuas ntxiv cov yeeb yaj kiab, txuas ntxiv cov yeeb yaj kiab. Cov yeeb yaj kiab no txhim kho adhesion, durability, thiab huab cua tsis kam ua cov txheej txheej, cov nplaum nplaum, thiab cov tshuaj pleev ib ce.
3. Txhim kho Adhesion: RPP txhim kho cov nplaum ntawm cov nplaum ntawm cov nplaum thiab cov khoom lag luam, lossis cov nplaum, ua rau muaj cov ntaub ntawv txhim kho kom zoo dua qub hauv kev tsim kho thiab hauv tsev.
4. Dej khaws cia: lub hydrophilic xwm ntawm RPP ua rau lawv nqus dej nyob rau hauv creadulations, qhib lub sijhawm ua haujlwm, thiab cov nplaum thiab cov ntaub ntawv nplaum vuas.
5. Yooj taus thiab tawv: RPP-hloov cov khoom pom tau nce ntxiv, elasticity, ua rau lawv tiv taus kev tawg, deformation, thiab kev cuam tshuam kev puas tsuaj, thiab cuam tshuam rau lawv.
6. Huab cua tiv thaiv: RPPs txhim kho huab cua tsis kam thiab kev tiv thaiv kev siv hluav taws xob, muab cov dej tsis ntev los tiv thaiv UV hluav taws xob, noo noo, thiab ib puag ncig thiab ib puag ncig.

Cov Ntawv Thov:

Recispersible polymer pilders pilders nrhiav kev thov kom muaj ntau yam kev lag luam thiab cov khoom lag luam, suav nrog:

• Kev Tsim Kho: Pobzeb Cov Khoom Siv, Tshuaj Khib, Tshuaj Tso Dej, Kev Tso Tawm Ntawm Kev Ntsuas Tus Kheej, thiab Rwb Sab Nraud (EIFS).
• Xim thiab pleev xim: Cov xim tha xim sab nraud, cov duab nplaum, cov plasters zoo nkauj, thiab txheej txheem ua yeeb yam.
• Cov nplaum thiab cov foob pob zeb: cov thawv nplaum sib xyaw, cov thawv tawg, caulks, yooj yim cov nplaum.
• Textiles: textile txheej, ua tiav cov neeg ua kom tiav, thiab sizing tebchaw.

Redispersible polymer hmoov yog ntau yam khoom siv los txhim kho kev tsim kho, cov qauv ntawm ntau yam khoom siv thiab cov khoom nplaum, cov khoom nplaum, thiab lwm yam khoom lag luam.
