Hmoov polymer uas yaj tau dua (RDP)yog ib qho hmoov uas ntws dawb uas tsim los ntawm kev tsuag-qhuav ib qho emulsion. Thaum kov nrog dej, nws sai sai rov ua dua los ua ib qho polymer emulsion ruaj khov nrog cov khoom zoo ib yam li cov emulsion qub. Ua ib qho polymer additive, RDP yog siv dav hauv cov ntaub ntawv tsim kho, cov nplaum, cov tshuaj pleev xim, cov tshuaj caulking, thiab lwm yam teb, ua lub luag haujlwm tseem ceeb hauv kev txhim kho kev ua tau zoo ntawm cov khoom thiab cov txiaj ntsig ntawm kev tsim kho.
1. Cov Ntawv Thov Hauv Cov Khoom Siv Hauv Tsev
Kev lag luam kev tsim kho yog daim ntawv thov siv dav tshaj plaws rau RDP, tshwj xeeb tshaj yog hauv cov mortars qhuav. Nws cov kev siv tseem ceeb suav nrog:
Cov nplaum rau pobzeb: RDP tuaj yeem txhim kho lub zog sib txuas thiab kev ywj pheej ntawm cov nplaum rau pobzeb, tswj cov khoom sib txuas zoo heev hauv qhov kub thiab txias siab, nrog rau hauv qhov chaw noo noo. Hmoov Putty thiab Cov Txheej Txheem Rwb Thaiv Phab Ntsa Sab Nraud: Ntxiv RDP rau putty ua rau muaj kev tiv thaiv dej, tiv thaiv huab cua, thiab kev nplaum. Hauv cov txheej txheem rwb thaiv tsev sab nraud (EIFS), RDP txhim kho kev sib txuas ntawm cov mortar thiab lub rooj tsavxwm rwb thaiv tsev, thaum tseem ua rau muaj kev tawg thiab kev cuam tshuam.
Cov gypsum-based lossis cement-based mortars: RDP txhim kho cov mortar qhov kev khaws cia dej, kev ua haujlwm tau zoo, thiab cov khoom flexural, tiv thaiv kev tawg thiab ntev nws lub neej kev pabcuam.
2. Lub Luag Haujlwm hauv Kev Txhim Kho Pem Teb Tus Kheej
Cov ntaub ntawv uas nws tus kheej leveling xav tau kev ntws zoo heev thiab kev tiv taus kev sib txhuam. RDP lub luag haujlwm hauv cov cheeb tsam no suav nrog:
Ua kom lo rau txheej hauv paus kom tiv thaiv kev hollowing lossis flaking.
Ua kom lub zog compressive thiab flexural zog ntxiv rau kev ua kom hauv pem teb ruaj khov dua.
Txhim kho kev ua haujlwm ntawm kev tsim kho, ua kom muaj kev ntws dej sib npaug thiab qhov chaw du.
3. Siv rau hauv Cov Khoom Siv Tiv Thaiv Dej thiab Kho Cov Pob Zeb
RDP qhov kev ywj pheej zoo heev thiab cov yam ntxwv ua zaj duab xis ua rau nws yog ib qho kev hloov pauv zoo rau cov mortars tiv thaiv dej. Hauv cov mortar tiv thaiv dej, RDP txhim kho qhov tsis pub dej nkag thiab kev ywj pheej ntawm cov txheej tiv thaiv dej thiab ua kom muaj zog ntawm kev sib txuas ntawm cov mortar thiab cov substrate.
Hauv cov tshuaj khib kho, RDP txhim kho qhov tsis kam tawg, ua kom muaj kev sib txuas zoo ntawm cov txheej kho thiab cov khoom qub.
4. Daim Ntawv Thov Hauv Pobzeb Grout
Cov pob zeb grout xav tau kev tiv thaiv dej thiab kev tiv thaiv tawg. Lub luag haujlwm tseem ceeb ntawm RDP hauv grout yog:
Txhim kho qhov kev sib txuas ntawm cov grout thiab cov pobzeb, tiv thaiv kev tawg thiab tev tawv.
Muab cov dej zoo thiab cov pwm tsis kam, ua kom muaj txiaj ntsig zoo nkauj mus sij hawm ntev.
Txhim kho kev ua haujlwm tau zoo, ua rau cov grouting du thiab tsis tshua muaj kev cuam tshuam rau shrinkage.
5. Daim Ntawv Thov Hauv Kev Sib Koom Ua Ke Insulation thiab Decoration Systems
Nrog rau qhov kev thov nce ntxiv rau cov tsev txuag hluav taws xob, RDP ua lub luag haujlwm tseem ceeb hauv kev rwb thaiv tsev thiab kho kom zoo nkauj:
Txhim kho qhov kev tiv thaiv huab cua tag nrho thiab lub zog sib txuas ntawm lub cev.
Txhim kho kev tiv thaiv kev cuam tshuam thiab kev tawg, ua kom ruaj khov mus sij hawm ntev.
Pab txhawb kev sib txuas nrog ntau yam khoom siv (xws li EPS thiab XPS boards), xyuas kom meej tias tag nrho cov kev ua haujlwm ntawm lub kaw lus rwb thaiv tsev.
6. Cov Ntawv Siv Hauv Cov Nplaum Thiab Cov Tshuaj Sealants
Ntxiv rau cov tshuaj khib tsev, RDP kuj tseem siv rau hauv cov nplaum thiab cov khoom siv foob hauv kev lag luam thiab hauv tsev.
Hauv cov kua nplaum ntoo thiab ntawv, RDP muab kev nplaum zoo heev thiab ua kom ruaj khov.
Hauv cov sealants, RDP muab elasticity thiab dej tsis kam, ntev lub neej kev pabcuam.
7. Cov Ntawv Thov Hauv Cov Txheej Txheem Thiab Kev Hloov Kho
RDP siv tau ua tus hloov kho hauv cov xim thiab cov hmoov txheej:
Muab cov yeeb yaj kiab zoo thiab tiv taus huab cua.
Txhim kho kev tiv thaiv alkali thiab kev tiv thaiv scrubber, ua rau nws tsim nyog rau cov txheej txheem phab ntsa sab nraud thiab cov txheej txheem ua haujlwm.
Txhim kho qhov kev sib txuas ntawm cov txheej thiab cov substrate, tiv thaiv kev sib cais.
8. Cov txiaj ntsig zoo ntawm RDP
Kev siv dav dav ntawm RDP hauv ntau qhov chaw yog vim muaj cov txiaj ntsig hauv qab no:
Muaj zog rov ua dua tshiab: Rov qab mus rau hauv cov emulsion thaum kov dej, ua rau yooj yim khaws cia thiab thauj mus los.
Kev Siv Tau Ntau Yam: Tib lub sijhawm txhim kho kev nplaum, kev ywj pheej, kev tiv thaiv kab nrib pleb, thiab kev tiv thaiv dej.
Kev Ua Haujlwm Tau: Txhim kho kev ua haujlwm tau ntawm cov khoom sib tov qhuav thiab ua kom yooj yim rau kev tuav. Siv tau dav: Nws tuaj yeem siv rau ntau yam tshuab, suav nrog cov tshuab ua los ntawm cement, gypsum, thiab lime.
Ua ib qho tseem ceeb polymer modifier,RDPtau dhau los ua ib qho khoom siv tseem ceeb hauv kev lag luam tshuaj siv hauv kev tsim kho. Nws ua lub luag haujlwm tseem ceeb hauv ntau yam kev siv, suav nrog cov nplaum rau pobzeb, cov screed uas ua rau nws tus kheej zoo li tus kheej, cov txheej txheem rwb thaiv tsev ntawm phab ntsa sab nraud, cov tshuaj mortar uas tsis muaj dej, cov neeg sawv cev caulking, cov tshuaj pleev xim, thiab cov nplaum. Los ntawm kev txhim kho kev nplaum, kev ywj pheej, kev tiv thaiv dej, thiab kev tiv thaiv huab cua, RDP ua rau kev ua haujlwm thiab lub neej ua haujlwm ntawm cov ntaub ntawv zoo dua. Nrog rau kev txhim kho cov ntaub ntawv siv hauv tsev ntsuab thiab txuag hluav taws xob, cov chaw siv RDP yuav txuas ntxiv nthuav dav, thiab nws lub luag haujlwm hauv kev lag luam kev tsim kho yav tom ntej yuav tseem ceeb dua.
