Hmoov Polymer Redispersible (RDP) yog cov hmoov polymer uas tau los ntawm kev tsuag kom qhuav cov polymer dispersion. Cov hmoov no tuaj yeem rov ua dua hauv dej los ua cov latex uas muaj cov khoom zoo ib yam li cov polymer dispersion qub. RDP feem ntau siv hauv kev lag luam kev tsim kho ua cov khoom siv tseem ceeb hauv cov ntaub ntawv tsim kho. Nov yog kev piav qhia txog RDP hauv cov ntsiab lus ntawm cov ntaub ntawv tsim kho:
Cov yam ntxwv tseem ceeb ntawm RDP hauv cov ntaub ntawv tsim kho:
1. Txhim Kho Kev Ywj Pheej thiab Kev Sib Txuas:
– RDP ua rau cov khoom siv hauv tsev xws li cov mortars, cov nplaum pobzeb, thiab cov renders muaj kev ywj pheej thiab kev nplaum zoo dua. Qhov no tseem ceeb heev rau cov ntawv thov hauv kev tsim kho uas qhov ruaj khov thiab lub zog tseem ceeb heev.
2. Kev Khaws Dej:
– RDP txhim kho lub peev xwm khaws dej ntawm cov khoom siv hauv tsev, ua kom ntseeg tau tias cov khoom sib xyaw ua ke muaj dej txaus. Qhov no pab ua kom yooj yim ua haujlwm thiab ntev lub sijhawm qhib rau cov ntawv thov xws li cov nplaum pobzeb.
3. Kev Sib Koom Siab Thiab Lub Zog Ntau Ntxiv:
– Hauv cov mortars thiab renders, RDP ua haujlwm ua ib qho binder, txhim kho qhov sib koom ua ke ntawm cov khoom siv thiab txhim kho lub zog. Qhov no yog qhov tseem ceeb rau cov ntawv thov uas qhov kev ua kom ruaj khov yog qhov tseem ceeb.
4. Txo Qhov Ntsws:
– Kev siv RDP rau hauv cov ntaub ntawv tsim kho pab txo qhov kev ntsws thaum lub sijhawm ziab. Qhov no yog qhov tseem ceeb rau kev tiv thaiv kev tawg thiab xyuas kom ruaj khov mus sij hawm ntev ntawm cov qauv.
5. Kev Tiv Thaiv Kev Cuam Tshuam Zoo Dua:
- RDP pab txhawb rau qhov cuam tshuam ntawm cov txheej txheem thiab cov khoom siv, muab cov txheej tiv thaiv uas tuaj yeem tiv taus cov zog sab nraud.
6. Kev Ua Haujlwm Zoo Dua:
– Kev siv RDP ua rau cov khoom siv hauv kev tsim kho ua haujlwm tau zoo dua, ua rau lawv yooj yim dua rau kev sib tov, siv, thiab ua kom zoo nkauj. Qhov no muaj txiaj ntsig zoo thaum lub sijhawm tsim kho.
Cov ntawv thov hauv cov ntaub ntawv siv hauv tsev:
1. Cov nplaum thiab cov grout rau pobzeb:
– RDP feem ntau siv rau hauv cov nplaum rau pobzeb thiab cov grouts kom txhim kho kev nplaum, kev ywj pheej, thiab kev tiv thaiv dej. Nws pab ua kom cov pobzeb nyob ruaj khov.
2. Cov Txheej Txheem Rwb Thaiv Sab Nraud thiab Cov Txheej Txheem Ua Kom Tiav (EIFS):
- RDP siv rau hauv EIFS los txhim kho qhov kev sib txuas thiab kev ywj pheej ntawm lub kaw lus. Nws kuj tseem pab txhawb rau lub kaw lus lub zog thiab kev tiv taus cov yam ntxwv ib puag ncig.
3. Cov Cuab Yeej Thiab Cov Qauv:
- Hauv cov mortars thiab renders, RDP ua haujlwm ua ib qho tseem ceeb rau kev txhim kho kev sib koom ua ke, lub zog, thiab kev ua haujlwm tau zoo. Nws pab tiv thaiv kev tawg thiab txhim kho kev ua haujlwm tag nrho.
4. Cov Tshuaj Sib Xyaws Uas Ua Rau Nws Tus Kheej Sib Npaug:
– RDP siv rau hauv cov tshuaj sib xyaw ua ke kom nws tus kheej sib npaug zoo dua qub thiab ua kom nws cov dej ntws zoo dua qub. Qhov no tseem ceeb heev rau kev ua kom du thiab tiaj tiaj.
5. Cov Khoom Siv Gypsum:
- RDP tuaj yeem koom ua ke rau hauv cov khoom lag luam gypsum kom txhim kho lawv cov nplaum, tiv taus dej, thiab kev ua tau zoo tag nrho.
Cov Kev Xav Txog Kev Xaiv:
1. Hom Polymer:
– Cov RDP sib txawv yuav yog raws li ntau hom polymer, xws li vinyl acetate ethylene (VAE) lossis styrene butadiene (SB). Qhov kev xaiv nyob ntawm qhov xav tau tshwj xeeb ntawm daim ntawv thov.
2. Tus Nqi Tshuaj:
- Qhov ntau npaum li cas ntawm RDP hauv cov qauv yog nyob ntawm cov yam xws li hom khoom siv hauv tsev, cov khoom xav tau, thiab cov kev xav tau ntawm daim ntawv thov.
3. Kev Sib Haum Xeeb:
- Kev xyuas kom meej tias muaj kev sib raug zoo nrog lwm cov khoom xyaw hauv cov mis yog qhov tseem ceeb rau kev ua tiav qhov kev ua tau zoo ntawm cov khoom siv hauv tsev.
4. Cov Qauv Zoo:
- RDP yuav tsum ua tau raws li cov qauv zoo thiab cov lus qhia kom ntseeg tau tias muaj kev ua tau zoo thiab txhim khu kev qha hauv kev siv kev tsim kho.
Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias cov qauv tshwj xeeb thiab cov lus qhia siv yuav txawv ntawm cov chaw tsim khoom thiab cov khoom. Yog li ntawd, kev sab laj nrog cov neeg muag khoom thiab ua raws li lawv cov lus pom zoo yog qhov tseem ceeb rau cov txiaj ntsig zoo tshaj plaws.
