Redispersible latex hmoov (RDP) yog cov khoom siv ntau yam thiab muaj txiaj ntsig zoo hauv cov tshuaj khib nyiab uas muaj ntau yam txiaj ntsig uas txhim kho kev ua haujlwm thiab ua haujlwm ntev ntawm cov khoom siv tshuaj khib nyiab.Mortar yog ib qho sib xyaw ntawm cov cement, xuab zeb thiab dej uas feem ntau siv hauv kev tsim kho los khi cov masonry units thiab muab cov qauv kev ncaj ncees rau lub tsev.Kev koom ua ke ntawm redispersible latex hmoov rau hauv mortar formulations tau nrov zuj zus vim nws qhov cuam tshuam zoo rau ntau yam khoom.
1. Txhim kho adhesion thiab kev sib txuas ua haujlwm:
Qhov sib ntxiv ntawm redispersible latex hmoov zoo txhim kho qhov adhesion ntawm mortar rau ntau yam substrates.Qhov kev txhim kho adhesion no yog qhov tseem ceeb los xyuas kom muaj kev ruaj khov thiab kav ntev ntawm cov mortar thiab masonry units.Cov ntaub ntawv polymer tsim cov zaj duab xis hloov tau yooj yim tsis tau tawv thaum hydrated, txhawb kev sib cuag zoo dua nrog cov substrate thiab txo qhov kev pheej hmoo ntawm kev debonding lossis delamination.
2. Txhim kho yooj thiab tawg tsis kam:
Redispersible latex hmoov imparts saj zawg zog rau lub mortar matrix, ua rau nws ntau resistant rau cracking.Cov zaj duab xis polymer tsim thaum lub sij hawm hydration ua tus choj tawg, tso cai rau lub mortar kom haum rau me ntsis txav thiab kev ntxhov siab yam tsis muaj kev cuam tshuam nws cov qauv kev ntseeg.Qhov kev hloov pauv no tshwj xeeb tshaj yog muaj txiaj ntsig zoo hauv thaj chaw muaj kev hloov pauv kub thiab kev ua seismic.
3. Kev tuav dej thiab ua haujlwm tau zoo:
Cov dej tuav cov khoom ntawm redispersible latex hmoov pab txuas ntxiv kev ua haujlwm ntawm mortar.Cov khoom siv polymer zoo khaws cov dej molecules, tiv thaiv kom tsis txhob ya raws sai thiab siv sijhawm ntev.Qhov no yog qhov tshwj xeeb tshaj yog nyob rau hauv cov xwm txheej kub thiab qhuav vim nws muab cov neeg ua haujlwm tsim kho ntau lub sijhawm los tswj thiab tsim cov mortar ua ntej nws teeb tsa.
4. Ua kom durability thiab huab cua tsis kam:
Cov mortars uas muaj cov hmoov polymer dispersible pom tau tias muaj kev ruaj khov nyob rau hauv cov huab cua tsis zoo.Lub polymer membrane ua raws li kev tiv thaiv kev tiv thaiv, txo cov kev nkag mus ntawm dej thiab aggressive ib puag ncig cov ntsiab lus rau hauv mortar matrix.Qhov kev txhim kho huab cua tiv thaiv no ua rau lub tsev muaj kev ncaj ncees rau lub sijhawm ntev thiab txo cov kev xav tau ntawm kev saib xyuas.
5. Txo shrinkage:
Shrinkage yog ib qho teeb meem tshwm sim nrog cov tshuaj mortar thiab tuaj yeem ua rau kev loj hlob ntawm cov kab nrib pleb hauv lub sijhawm.Redispersible latex hmoov pab txo qis shrinkage los ntawm kev txhim kho cov khoom sib txuas ntawm cov tshuaj khib nyiab.Cov zaj duab xis hloov tau yooj yim polymer txo cov kev ntxhov siab sab hauv, txo qhov muaj peev xwm ntawm cov kab nrib pleb thiab txhim kho tag nrho cov kev ua tau zoo ntawm cov mortar.
6. Txhim kho khov-thaw tsis kam:
Cov mortars uas muaj redispersible latex hmoov tuaj yeem txhim kho kev tiv thaiv kom khov-thaw mus.Cov ntaub ntawv polymer muab cov txheej txheem tiv thaiv uas pab tiv thaiv cov dej los ntawm kev nkag mus rau hauv cov qauv mortar.Qhov no yog ib qho tseem ceeb nyob rau hauv cov huab cua txias, qhov uas nthuav thiab contraction ntawm cov dej thaum lub sij hawm khov thiab thawing yuav ua rau deterioration ntawm tsoos mortar.
7. Compatibility nrog ntau yam additives:
Redispersible latex hmoov yog sib xws nrog ntau yam additives, tso cai rau cov formulation ntawm tshwj xeeb mortars nrog customized zog.Qhov no versatility ua rau kev txhim kho ntawm mortars haum rau cov kev siv tshwj xeeb, xws li ceev-teeb mortars, self-leveling mortars los yog mortars tsim rau siv nyob rau hauv tej yam kev mob.
8. Green Building thiab Sustainable Construction:
Kev siv cov hmoov latex redispersible hauv mortars yog ua raws li kev coj ua vaj tsev ntsuab thiab kev tsim kho kom ruaj khov.Kev txhim kho kev ua tau zoo thiab ua haujlwm ntev ntawm cov khoom siv polymer-hloov pab txuas ntxiv lub neej kev pabcuam ntawm cov qauv thiab txo qhov xav tau kev kho thiab hloov ntau zaus.Tsis tas li ntawd, qee cov hmoov latex redispersible yog tsim los siv cov txheej txheem ib puag ncig thiab tej zaum yuav muaj cov ntsiab lus siv dua.
9. Txhim kho kev zoo nkauj:
Kev txhim kho kev ua haujlwm thiab kev sib koom ua ke ntawm polymer-hloov mortars pab ua kom tiav ib qho smoother, zoo ib yam.Qhov no yog qhov tseem ceeb tshwj xeeb hauv cov ntawv thov uas qhov zoo nkauj ntawm cov tshuaj khib nyiab yog qhov tseem ceeb ntawm kev xav, xws li cov ntsiab lus ntawm cov vaj tse lossis cov cib raug pom.
10. Kev daws teeb meem raug nqi:
Thaum redispersible latex hmoov yuav ntxiv rau tus nqi pib ntawm kev tsim cov tshuaj khib nyiab, cov txiaj ntsig ntev hauv kev txo qis, kev pab lub neej ntev thiab kev ua tau zoo dua feem ntau tshaj qhov pib peev.Tus nqi-zoo ntawm polymer-hloov mortars ua rau lawv muaj kev xaiv zoo rau ntau yam kev tsim kho.
Kev koom ua ke ntawm dispersible polymers rau hauv ER hmoov rau hauv mortar formulations muaj ntau yam txiaj ntsig uas cuam tshuam rau kev ua tau zoo, ua haujlwm ntev thiab tag nrho cov khoom siv hauv tsev.Los ntawm kev txhim kho adhesion thiab yoog mus rau kev txhim kho huab cua tiv thaiv thiab txo qis, cov txiaj ntsig no ua rau cov khoom siv polymer-hloov kho cov khoom muaj txiaj ntsig zoo rau ntau yam kev siv hauv kev tsim kho.Raws li kev siv thev naus laus zis txuas ntxiv mus, kev tsim kho tshiab ntxiv hauv cov khoom siv rov ua dua tshiab latex hmoov tuaj yeem pab txhawb kev txhim kho txuas ntxiv ntawm cov ntaub ntawv mortar kom muab cov kev daws teeb meem zoo dua qub thiab ua tau zoo rau thaj chaw tsim.
