Dab tsi yog lub tshuab ntawm kev ua ntawm cov liab liab polymer hmoov?

Lub tshuab ntawm kev ua ntawm redispersible hmoov polymer (RPP) muaj feem xyuam nrog dej thiab lwm yam ntawm kev txhim kho kev ua haujlwm thiab cov khoom. Ntawm no yog cov lus qhia ntxaws ntxaws ntawm cov txheej txheem ntawm kev ua ntawm RPP:

1. Recispersion hauv dej:
   • RPP yog tsim los disperse nkag rau hauv dej, tsim ruaj khov rau kev ncua lossis kev daws teeb meem. Qhov kev rov cai no yog qhov tseem ceeb rau lawv txoj kev sib xyaw ua kab kab ua qauv thiab kev siv dej tom ntej.
2. Zaj duab xis tsim:
   • Thaum Ripispersion, RPP sau ib zaj duab xis nyias lossis txheej ncig CIAS nkaus thiab lwm yam ntawm cug tshuaj matrix. Zaj yeeb yaj kiab no ua cov phau ntawv, khi cov lus ua ke thiab txhim kho cohesion nyob rau hauv lub cug.
3. Adhesion:
   • RPP zaj duab xis txhim kho cov nplaum ntawm choration ntawm choration ntawm choas sib xyaw (xws li, Maas, cov khoom siv sib xyaw) thiab cov chaw ua vaj tse (piv txwv li, masonry). Qhov kev ua kom zoo dua cov nplaum txwv tsis pub cuam tshuam kev txiav txim siab thiab ua kom muaj kev sib raug zoo ntawm cov tshuaj khib thiab txheej.
4. Dej khaws cia:
   • RPP muaj hydrothilic cov khoom uas ua kom lawv nqus thiab khaws dej nyob hauv lub kab tshuaj khib matrix. Qhov kev nce hauv dej ntau zuj zus mus ntev ntev ua kom lub sijhawm ua kom zoo nkauj, ua kom muaj kev ua haujlwm qhib zoo, thiab txhim kho adhesion.
5. Yooj thiab elasticity:
   • RPP impart yooj thiab elasticity rau lub tshuaj khib matrix, ua rau nws tiv thaiv ntau dua thiab deformation. Qhov kev hloov kho no tso cai rau kev txig ua kom haum rau kev txav mus los thiab cov cua sov nthuav tawm tsis muaj kev ncaj ncees.
6. Txhim kho cov haujlwm ua haujlwm:
   • Lub xub ntiag ntawm RPP txhim kho kev ua haujlwm thiab sib xyaw ntawm cug, ua rau nws sib xyaw, thov, thiab kis. Qhov kev ua haujlwm zoo no tso cai rau kev pab them nqi zoo dua thiab ntau dua cov khoom siv tsis zoo, txo qhov ua kom zoo li ntawm voids lossis khoob hauv cov qoob loo tiav.
7. Durability Ehhancement:
   • RPP-hloov cov neeg tsis muaj kev ua tau zoo ua kom muaj kev txhim kho durability vim lawv ua kom muaj kev tiv thaiv kom huab cua, tshuaj tua rog, thiab kev puas tsuaj. RPP zaj duab xis ua raws li kev tiv thaiv kev tiv thaiv, thaiv cov tshuaj khib los ntawm sab nraud neeg ua phem thiab lub sijhawm ua haujlwm ntev.
8. Kev tso tawm kev tso tawm ntawm cov ntxiv:
   • RPP muaj peev xwm encapsulate thiab tso cov khoom xyaw ua kom muaj cov khoom xyaw lossis cov tshuaj ntxiv (piv txwv li cov tshuab yas, cov tshuab tsuj, nrawm dua) hauv lub tshuaj khib. Qhov no tswj kev kho tshuab tso tawm mechanism tso cai rau kev ua kom haum thiab customized cov qauv ua kom tau raws li cov ntawv thov kev thov.

Cov txheej txheem ntawm kev ua ntawm refispersible hmoov polymer muaj kev txhim kho, kev ua yeeb yaj kiab, kev ua haujlwm ruaj khov, thiab kev tswj hwm kev sib ntxiv ntawm cov quav ntxiv. Cov txheej txheem sib txuas lus sib xyaw ua ke rau kev txhim kho kev ua tau zoo thiab cov yam ntxwv ntawm RPP-hloov mortars nyob rau ntau yam kev siv.
