Redispersible polymer hmoov (RDP) yog qhov tseem ceeb rau cov khoom siv hauv tsev, xws li qhuav-tov cov nplaum thiab cov tshuab rwb thaiv tsev. Nws lub ntsiab tivthaiv yog feem ntau ethylene-vinyl acetate copolymer (Eva), ethylene-vinyl acrylic acid acid copolymer (sa). RDP ua kom cov ntaub ntawv tsim tsev kom tau txais txiaj ntsig zoo hauv lawv cov ntawv thov los ntawm kev txhim kho lawv lub cev thiab tshuaj lom neeg.
1. Txhim Kho Cov Khoom Tshuas
Ib qho txiaj ntsig tseem ceeb ntawm RDP yog tias nws ua tau zoo rau lub zog sib luag ntawm cov ntaub ntawv tsev. Ntxiv RDP kom qhuav cov tshuaj khib tov ua tau zoo txhim kho txoj kev sib cais ntawm lub cug cug thiab ntau hom substrates. Qhov no yog qhov tshwj xeeb tshaj nrog cov nplais nplaum raws li nws ua kom cov vuas ua kom muaj kev nyab xeeb rau phab ntsa lossis hauv pem teb, txo txoj kev pheej hmoo ntawm cov hollowing thiab poob tawm.
2. Txhim kho kom haum thiab tawg
Qhov hloov tau yooj yim thiab tawg ntawm cov ntaub ntawv lub tsev muaj lub neej ncaj thiab lub neej ruaj khov. RDP tseem ceeb txhim kho qhov hloov tau ntawm cov khoom los ntawm kev tsim cov duab sib dhos sab hauv cov khoom thiab deformation, yog li txo qhov tshwm sim ntawm cov kab nrib pleb. Qhov no yog qhov tshwj xeeb tshaj yog rau sab nrauv phab ntsa rwb thaiv tsev tshuab (EIFS) thiab cov plag tsev tus kheej.
3. Txhim Kho Dej Kuj
RDP tuaj yeem rov kho dua rau hauv qhov ruaj khov emulsion nyob rau hauv cov hmoov qhuav, muab cov khoom siv dej tsis kam tiv thaiv. Nyob rau hauv ib puag ncig ntub dej, RDP-ntxiv Mortar thiab cov nplaum muaj peev xwm tswj tau cov nyiaj tau los ntawm lub zog thiab kav ntev. Qhov no yog qhov tseem ceeb tshaj plaws rau cov ntaub ntawv tsim hauv cov chaw ntub xws li chav dej thiab chav ua noj.
4. Txhim Kho Kev Siv Kev Siv
RDP txhim kho cov yam ntxwv ntawm cug cug thiab lwm yam ntaub ntawv hauv tsev, ua rau lawv tsim thiab ua haujlwm. Piv txwv li, RDP tuaj yeem txhim kho lubricity thiab kev ua haujlwm ntawm cov khoom siv ntawm cov khoom siv hauv kev tsim kho thiab qib kev siv. Ib qho ntxiv, nws tuaj yeem txuas ntxiv teev teev teev, muab cov neeg ua haujlwm qhib ntau zaug los kho.
5. Nce khov-thwawe
Hauv cov huab cua txias, cov ntaub ntawv tsim tsev yuav tsum muaj qhov khov khov-thaws tsis kam tiv thaiv cov khoom los ntawm kev tawg vim qhov ntsuas kub. RDP txhim kho cov khoom khov-thaws ua kom tsis kam los ntawm kev txhim kho nws cov khoom siv kev ntseeg siab thiab ua haujlwm thaum rov ua haujlwm khov-thaw mus.
6. Txhim Kho Cov Hnav Tsis kam
Daim ntawv thov ntawm RDP hauv cov khoom hauv pem teb tuaj yeem txhim kho cov kev coj ua kom tsis kam thiab ruaj khov ntawm hauv av. Qhov no yog qhov tshwj xeeb tshaj yog rau cov ntaub ntawv tsim hauv av uas yuav tsum tau ua kom muaj cov neeg ua haujlwm siab thiab ntau cov khw muag khoom, tshav dav hlau thiab cov chaw nres tsheb dav hlau.
7. Txhim kho cov shrinkage kev tshuaj khib
Thaum lub sij hawm ua cov txheej txheem tawv ntawm cug, shrinkage yog ib qho ntawm qhov ua rau tawg thiab deformation. RDP txo cov shrinkage ntawm txoj kev sib khib ntawm kev sib xyaw ua ke membrane qauv hauv lub tshuaj khib, yog li tiv thaiv kev tiv thaiv zoo tawg thaum lub sij hawm tawv.
8. Kev tiv thaiv ib puag ncig thiab kev ruaj khov
Raws li cov dej-soluble polymer, RDP lub chaw ua haujlwm ib puag ncig kuj yog ib qho ntawm cov kev tsim kho ntawm kev tsim kho. Thaum lub sijhawm tsim khoom thiab cov txheej txheem kev lag luam ntawm RDP, feem ntau tsis muaj lossis me organic huab cua, uas txo cov pa phem ib puag ncig. Tsis tas li ntawd, vim RDP tuaj yeem txhim kho kev ua tau zoo thiab lub neej muaj txiaj ntsig, nws tsis ncaj rau cov kev cai txhim kho hauv kev lag luam niaj hnub.
Daim ntawv thov ntawm redispersible looj hmoov (RDP) hauv cov ntaub ntawv tsim vaj tsev tau coj ntau yam kev txhim kho rau kev ua haujlwm ntawm cov ntaub ntawv thiab kev tsim kho. Los ntawm kev txhim kho adhesion, yooj yim, dej tsis kam thiab ua tsis kam, RDP tseem ceeb txhim kho cov khoom siv hauv tsev. Tsis tas li ntawd, cov khoom ib puag ncig zoo ntawm RDP kuj ua rau nws tsis tseem ceeb hauv kev tsim kho niaj hnub. Nrog kev txhim kho kev ua haujlwm txuas ntxiv ntawm kev tsim kho thev naus laus zis, RDP yuav ua lub luag haujlwm tseem ceeb tshaj plaws hauv lub neej tom ntej, txhawb kev tiv thaiv kev ua haujlwm ntawm cov kev ua tau zoo thiab ntau qhov kev tiv thaiv ib puag ncig.
