Redispersible polymer hmoov (RDP) yog nrov raws li ib qho tseem ceeb additive nyob rau hauv cov pobzeb nplaum formulations. Nws yog cov hmoov polymer uas ua los ntawm cov tshuaj tsuag kom qhuav dej raws li latex emulsion. Nws muaj ntau yam zoo hauv kev txhim kho kev ua tau zoo ntawm cov nplais nplaum, xws li txhim kho adhesion, cohesion thiab dej tsis kam, thiab lwm yam. Nyob rau hauv tsab xov xwm no, peb ua tib zoo saib lub luag hauj lwm ntawm RDP nyob rau hauv daim ntawv thov cov nplaum nplaum.
1. Txhim kho cohesion thiab adhesion
Ib qho ntawm cov ntawv thov tseem ceeb ntawm RDP hauv kev lag luam pobzeb nplaum yog txhawm rau txhim kho lub zog ntawm cov nplaum. RDP txhim kho qhov adhesion ntawm cov nplaum rau saum npoo thiab cohesion ntawm cov nplaum nplaum. Qhov no tso cai rau kev txhim kho lub peev xwm los tuav cov pobzeb nyob rau hauv qhov chaw ntev dua yam tsis muaj kev puas tsuaj rau substrate lossis pobzeb.
2. Txhim kho dej tsis kam
Ntxiv rau kev txhim kho daim ntawv cog lus, RDP tuaj yeem txhim kho cov dej tsis kam ntawm cov nplais nplaum. Thaum sib xyaw nrog cov cement, RDP txo cov dej nqus ntawm cov nplaum, ua rau nws zoo tagnrho rau thaj chaw uas muaj cov av noo siab. Nws txhim kho cov nplaum tiv thaiv rau cov dej nkag, yog li txo qhov kev pheej hmoo ntawm pobzeb detachment thiab kev puas tsuaj rau lub substrate.
3. Txhim kho qhov yooj yim
Cov pobzeb nplaum tau yooj yim puas los ntawm kev hloov kub, kev co thiab lwm yam sab nraud. Redispersible latex hmoov muab cov nplaum nplaum zoo dua thiab elasticity, txo qhov kev pheej hmoo ntawm kev tawg thiab kev puas tsuaj. Tsis tas li ntawd, nws txhim kho cov nplaum lub peev xwm los tiv thaiv qhov kub thiab txias hloov thiab tiv thaiv shrinkage, ua rau nws zoo tagnrho rau siv nyob rau hauv cov huab cua sib txawv.
4. Kev ua haujlwm zoo dua
Cov txheej txheem ntawm cov nplais nplaum yog hais txog lawv qhov yooj yim ntawm daim ntawv thov, sib tov thiab sib kis. RDP txhim kho cov txheej txheem ntawm cov nplaum los ntawm kev txhim kho nws cov yam ntxwv ntws, ua kom yooj yim sib xyaw thiab sib kis. Nws kuj tseem txo qis sagging thiab zawv zawg ntawm cov vuas thaum lub sijhawm teeb tsa, muab kev sib dhos zoo dua thiab txo cov khib nyiab.
5. Ua kom ruaj khov
Pobzeb nplaum tsim nrog RDP yog qhov ruaj khov thiab kav ntev. Nws txhim kho cov nplaum nplaum, kev cuam tshuam thiab kev puas tsuaj, ua rau nws zoo tagnrho rau siv hauv cov tsheb loj lossis cov chaw thauj khoom hnyav. Cov nplaum nplaum ntxiv kuj txhais tau tias tsawg dua kev tu thiab kho cov kev xav tau, ua rau cov nqi txuag rau cov neeg siv.
nyob rau hauv xaus
Redispersible polymer hmoov muaj ntau yam zoo thaum siv hauv cov pobzeb nplaum formulations. Nws txhim kho cov nplaum nplaum lub zog, dej tsis kam, yoog raws, kev ua haujlwm thiab ua haujlwm ntev, ua rau nws zoo tagnrho rau ntau yam kev siv. Tsis tas li ntawd, nws yog ib qho kev daws teeb meem uas muaj txiaj ntsig zoo uas muab kev ua haujlwm ntev ntev thiab txo qhov kev xav tau ntawm kev kho thiab tu ntau zaus. Zuag qhia tag nrho, RDP tau dhau los ua ib qho tseem ceeb ntxiv hauv kev lag luam pobzeb nplaum, thiab nws qhov kev thov yuav tsum txuas ntxiv mus ntxiv rau yav tom ntej.
