Lub luag haujlwm ntawm redispersible looj cov hmoov av hauv cov pobzeb nplaum feem ntau muaj cov hauv qab no

Cov hmoov polymer polymer, tseem hu ua cov hmoov polymer lossis RDP luv, yog ib qho khoom xyaw tsis tseem ceeb hauv cov nplais niaj hnub. Nws yog cov hmoov dawb lossis tawv-dawb-soluble hmoov tau txais los ntawm cov tshuaj tsuag-kom qhuav ntawm hluav taws xob polymer emulsion, tiv thaiv polulsion thiab lwm yam ntxiv. Thaum ntxiv rau cov tshuaj khib, RDP tuaj yeem txhim kho nws cov nyiaj ua haujlwm, yoog raws, dej tsis kam thiab ua haujlwm.

Lub luag haujlwm ntawm RDP nyob rau hauv cov pobzeb nplaum tuaj yeem suav tau ua ntej raws li hauv qab no:

1. Txhim kho adhesion: RDP tuaj yeem txhim kho cov nplaum ntawm cov vuas luaj li, xws li pob zeb ua ke, thiab lwm yam. Cov yeeb yaj kiab kuj txhim kho cov ntub dej thiab nthuav tawm cov nplaum thiab tiv thaiv nws los ntawm ziab nrawm dhau los yog tawg.

2. Txhim kho kev ua haujlwm: RDP tuaj yeem txhim kho cov haujlwm ua haujlwm thiab muaj kuab clile los ntawm kev siv dej txo, nce ntxiv, thiab txo sagging. Qhov no yog vim RDP tuaj yeem ua raws li cov roj nplua nyeem thiab ib phau ntawv, uas tuaj yeem txhim kho kom zoo thiab cohesion ntawm lub cug. Siv RDP kuj tseem txo lub sijhawm sib xyaw, nce lub sijhawm qhib, thiab txhim kho kev sib kis ntawm cov nplaum.

3. Kev hloov pauv tau zoo ntxiv thiab tsis muaj peev xwm tshwj xeeb ntawm cov vuas luaj thiab cov pob zeb uas yog qhov tseem ceeb rau kev tawg vim yog cov kev nthuav dav, kev co lossis txav. Qhov kev sib ntxiv ntawm RDP tuaj yeem nce cov elasticity thiab tensile lub zog ntawm cov nplaum thiab txo kev pheej hmoo ntawm delamination, debonding lossis detachment. Qhov no nce lub durability thiab kev ntev ntawm cov nplais.

4. Txhim kho cov dej tsis kam: RDP tuaj yeem txhim kho cov dej tsis kam ntawm cov nplais nplaum los ntawm kev txo cov pormeobility thiab porosity ntawm cug. Qhov no tiv thaiv dej, ya raws thiab ntsev los ntawm kev nkag mus rau substrate lossis pobzeb, uas yuav ua rau staining, huab cua lossis rot. RDP kuj nce qhov khov-thaw kev tawm tsam ntawm cov nplaum, uas yog qhov tseem ceeb sab nraum zoov thiab huab cua txias.

5. Kev tsim kho yooj yim: RDP tuaj yeem txo cov hmoov av, txhim kho cov nplaum thiab kev ua kom tawg thiab tawg, yog li ua rau cov kev tsim kho ntawm cov vuas luaj. Qhov no tuaj yeem txhim kho kev ua haujlwm ua haujlwm tau zoo thiab ua tau zoo, thiab txo cov nqi zog thiab cov nqi khoom siv. RDP kuj tseem tuaj yeem ua kom haum kom tau raws li cov kev cai tshwj xeeb ntawm cov vuas luaj, substrates thiab ib puag ncig.

RDP ua si lub luag haujlwm tseem ceeb heev thiab ntau yam hauv cov vuas luaj. Nws tuaj yeem txhim kho cov nplaum, kev ua haujlwm, dej tsis kam, dej tsis kam thiab ua haujlwm ntawm cov vuas nplaum, thiab txhim kho cov vuas ua tau zoo thiab muaj kev ruaj khov ntawm cov vuas. Kev siv ntawm RDP tseem tuaj yeem txhawb txoj kev loj hlob ntawm cov khoom lag luam ntsuab thiab cov roj carbon tsawg, uas tau txais txiaj ntsig rau ib puag ncig thiab tib neeg. Yog li ntawd, nws raug nquahu kom siv cov RDP zoo los ntawm cov neeg xa khoom kom ntseeg tau thiab ua raws li cov khoom siv tau pom zoo thiab cov txheej txheem sib tov.
