Vim li cas siv RDP hauv kev ua vaj tse

RDP, lossis cov tshuaj tiv thaiv polymer polymer, yog ib qho kev sib ntxiv siv hauv cov pob zeb ua rau ntau yam. Cov tshuaj ntxiv no yog qhov tseem ceeb polymer hmoov uas tuaj yeem tawg tawm hauv dej los ua ib zaj duab xis tom qab ziab. Ntawm no yog vim li cas RDP siv hauv kev ua vaj tse:

1. Txhim kho kev ua haujlwm ua haujlwm thiab Cohesion: RDP pab txhim kho kev ua haujlwm thiab cohesion ntawm pob zeb ua ke. Nws ua raws li kev tsis txaus siab, pab nyob rau hauv kev dispersion ntawm Maas hais thiab lwm yam additives thoob plaws qhov sib xyaw. Qhov no ua rau muaj homogogeneous ntau dua thiab yooj yim-rau-sib tov ua ke.
2. Txo cov dej nqus dej nqus: qhob muaj RDP feem ntau ua rau pom cov khoom nqus dej txo. Cov yeeb yaj kiab polymer tsim los ntawm RDP pab txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau hauv cov pob zeb ua kom zoo nkauj, txo kev ua pa thiab tiv thaiv cov dej ingress. Qhov no yog qhov tshwj xeeb tshaj yog rau kev txhim kho lub durability thiab kuj ntawm cov pob zeb ua kom noo noo kom noo noo-hais qhov tsis zoo.
3. Txhim kho cov roj flexural thiab tensile muaj zog: ntxiv rau ntawm RDP kom cov qauv sib luag tuaj yeem txhim kho cov khoom muaj zog thiab tensile lub zog ntawm lub ntsej muag ua tau zoo. The polymer film formed during hydration improves the bond between cement particles and aggregates, resulting in a denser and stronger concrete matrix.
4. Txhim kho adhesion thiab tsevneeg: RDP txhawb nqa zoo dua adhesion thiab tsev sib koom ua ke ntawm pob zeb txheej thiab substrates. Qhov no muaj txiaj ntsig zoo tshwj xeeb hauv kev kho thiab kho cov tshuab hloov kho, qhov twg cov pob zeb uas yuav tsum tau ua kom tau zoo rau cov pob zeb uas twb muaj lawm lossis substrates.
5. Txo cov shrinkage thiab tawg: RDP pab kom txo txoj kev pheej hmoo ntawm cov yas shrinkage thiab tawg hauv pob zeb. Cov yeeb yaj kiab polymer tsim los ntawm RDP ua raws li kev thaiv kom ya raws li kev kho kom zoo nkauj thaum ntxov thiab txo qis kev txhim kho ntawm shrinkage tawg.
6. Txhim kho khov-thaws tsis kam: qhob muaj RDP cov khoom pov cov khoom ua kom zoo dua kom khov-thaw mus. Cov yeeb yaj kiab polymer tsim los ntawm RDP pab kom txo qis permeability ntawm cov qhob tog hauv dej thiab lub peev xwm kom khov-thaws kev puas tsuaj nyob rau hauv huab cua txias.
7. Kev ua haujlwm zoo dua hauv kev ua haujlwm hnyav Cov yeeb yaj kiab polymer tsim los ntawm RDP pab kom ntub cov Maas hais, txo kev sib txhuam thiab ua kom yooj yim los txhuam thiab tso cov pob zeb sib xyaw.

Kev siv RDP hauv cov qauv sib luag muaj ntau cov txiaj ntsig, suav nrog kev txhim kho dej thiab ua kom tiav khov, txhim kho cov khoom khov kho, thiab txhim kho cov haujlwm tsis muaj zog, thiab txhim kho cov kev ua haujlwm tsis muaj zog. Cov txiaj ntsig no ua kom RDP ib qho tseem ceeb ntxiv rau kev ua haujlwm zoo thiab cov kav dej ruaj ruaj ntawm cov kev kho kev kho.
