Redispersible Polymer Powder (RDP) yog cov hmoov polymer-raws li tau txais los ntawm cov tshuaj tsuag kom qhuav cov polymer dispersion.Cov hmoov no tuaj yeem hloov pauv hauv dej los tsim cov latex uas muaj cov khoom zoo sib xws rau cov thawj polymer dispersion.RDP feem ntau yog siv nyob rau hauv kev tsim kho kev lag luam raws li ib tug tseem ceeb additive nyob rau hauv lub tsev cov ntaub ntawv.Nov yog cov ntsiab lus ntawm RDP hauv cov ntsiab lus ntawm cov khoom siv hauv tsev:
Cov yam ntxwv tseem ceeb ntawm RDP hauv Cov Khoom Siv Hauv Tsev:
1. Txhim kho Flexibility thiab Adhesion:
- RDP txhim kho qhov yooj yim thiab adhesion ntawm lub tsev cov ntaub ntawv xws li mortars, pobzeb adhesives, thiab renders.Qhov no yog qhov tseem ceeb tshwj xeeb hauv kev tsim cov ntawv thov uas muaj zog thiab lub zog tseem ceeb heev.
2. Kev tuav dej:
- RDP txhim kho cov dej tuav lub peev xwm ntawm cov khoom siv hauv tsev, ua kom cov dej kom zoo ntawm cov cementitious Cheebtsam.Qhov no ua rau muaj kev ua haujlwm zoo dua qub thiab ncua sijhawm qhib rau cov ntawv thov xws li pobzeb nplaum.
3. Ua kom muaj kev sib raug zoo thiab muaj zog:
- Hauv mortars thiab renders, RDP ua raws li kev khi, txhim kho kev sib koom ua ke ntawm cov khoom siv thiab txhim kho lub zog.Qhov no yog qhov tseem ceeb rau cov ntawv thov uas muaj kev ncaj ncees yog qhov tseem ceeb.
4. Txo Shrinkage:
- Kev koom ua ke ntawm RDP hauv cov khoom siv hauv tsev yuav pab txo qis qis thaum lub sijhawm ziab.Qhov no yog ib qho tseem ceeb rau kev tiv thaiv cov kab nrib pleb thiab ua kom muaj kev ruaj ntseg ntev ntawm cov qauv.
5. Txhim kho qhov cuam tshuam:
- RDP pab txhawb rau qhov cuam tshuam tsis zoo ntawm cov txheej txheej thiab ua kom pom, muab cov txheej txheem tiv thaiv uas tuaj yeem tiv taus sab nraud.
6. Ua haujlwm tau zoo:
- Kev siv RDP txhim kho kev ua haujlwm ntawm cov ntaub ntawv tsim kho, ua kom yooj yim rau kev sib xyaw, siv, thiab zoo li qub.Qhov no yog qhov zoo thaum lub sijhawm tsim kho.
Kev siv hauv cov khoom siv hauv tsev:
1. Pobzeb Adhesives thiab Grouts:
- RDP feem ntau yog siv rau hauv pobzeb nplaum thiab grouts los txhim kho adhesion, yooj, thiab dej tsis kam.Nws pab xyuas kom cov vuas nyob ruaj ntseg hauv qhov chaw.
2. Sab nrauv rwb thaiv tsev thiab Finish Systems (EIFS):
- RDP yog siv nyob rau hauv EIFS los txhim kho cov adhesion thiab yooj ntawm lub system.Nws kuj tseem txhawb nqa lub zog ua haujlwm thiab ua haujlwm rau ib puag ncig yam.
3. Mortars thiab Renders:
- Hauv mortars thiab renders, RDP ua qhov tseem ceeb ntxiv rau kev txhim kho kev sib raug zoo, lub zog, thiab kev ua haujlwm.Nws pab tiv thaiv cov kab nrib pleb thiab txhim kho kev ua haujlwm tag nrho.
4. Self-Leveling Compounds:
- RDP yog siv nyob rau hauv tus kheej-leveling compounds los txhim kho lawv cov dej ntws thiab adhesion.Qhov no yog ib qho tseem ceeb rau kev ua tiav qhov du thiab qib nto.
5. Gypsum-based khoom:
- RDP tuaj yeem muab tso rau hauv cov khoom siv gypsum los txhim kho lawv cov adhesion, dej tsis kam, thiab kev ua haujlwm tag nrho.
Kev txiav txim siab xaiv:
1. Hom Polymer:
- Cov RDPs sib txawv tuaj yeem ua raws li ntau hom polymer, xws li vinyl acetate ethylene (VAE) lossis styrene butadiene (SB).Qhov kev xaiv nyob ntawm qhov kev xav tau tshwj xeeb ntawm daim ntawv thov.
2. Tus nqi noj:
- Qhov ntau npaum li cas ntawm RDP nyob rau hauv ib tug formulation nyob ntawm tej yam xws li hom ntawm lub tsev cov ntaub ntawv, cov khoom uas xav tau, thiab daim ntawv thov yuav tsum tau.
3. Compatibility:
- Ua kom muaj kev sib raug zoo nrog lwm cov khoom xyaw hauv kev tsim khoom yog qhov tseem ceeb rau kev ua tiav qhov kev xav tau ntawm cov khoom siv hauv tsev.
4. Cov Qauv Zoo:
- RDP yuav tsum ua kom tau raws li cov qauv zoo thiab cov lus qhia tshwj xeeb los xyuas kom meej thiab txhim khu kev qha hauv kev tsim kho.
Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias cov txheej txheem tshwj xeeb thiab cov txheej txheem kev thov yuav txawv ntawm cov tuam ntxhab thiab cov khoom lag luam.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.
