Cov nplaum rau pobzeb yog ib yam khoom tseem ceeb uas siv los nplaum cov pobzeb ceramic, pob zeb thiab lwm yam khoom siv hauv tsev, thiab nws tseem yog ib qho tseem ceeb hauv kev tsim kho. Hauv cov mis ntawm cov nplaum rau pobzeb, RDP (Redispersible Polymer Hmoov) yog ib yam khoom ntxiv uas tsis tuaj yeem tsis tau. Kev ntxiv RDP tsis yog tsuas yog txhim kho kev ua haujlwm ntawm cov nplaum xwb, tab sis kuj txhim kho kev ua haujlwm ntawm kev tsim kho thiab txhim kho lub zog sib txuas.
1. Txhim kho lub zog sib txuas
Ib qho ntawm cov haujlwm tseem ceeb ntawm RDP hauv cov nplaum pobzeb yog los txhim kho lub zog sib txuas. Cov nplaum pobzeb yuav tsum tiv taus lub zog tensile thiab shear loj, thiab RDP tuaj yeem txhim kho qhov kev ua tau zoo ntawm cov nplaum. Tom qab cov khoom RDP sib xyaw nrog dej, lawv yuav tsim cov zaj duab xis polymer sib xws uas npog qhov chaw sib txuas. Cov zaj duab xis no muaj lub zog sib txuas siab thiab kev ywj pheej, thiab tuaj yeem sib txuas cov vuas ceramic rau lub substrate kom ruaj khov thiab zam kev nthuav dav thermal. Poob lossis tawg los ntawm kev txias shrinkage lossis lub zog sab nraud.
2. Txhim kho kev ua haujlwm ntawm kev tsim kho
Kev ua tau zoo ntawm cov nplaum pobzeb yog qhov tseem ceeb rau kev paub txog kev ua haujlwm ntawm cov neeg ua haujlwm tsim kho, tshwj xeeb tshaj yog nyob rau hauv cov haujlwm tsim kho loj, qhov twg kev ua haujlwm zoo thiab zoo ntawm kev tsim kho muaj feem cuam tshuam ncaj qha rau tus nqi thiab lub sijhawm ntawm qhov project. Kev ntxiv ntawm RDP tuaj yeem txhim kho qhov kev ua haujlwm thiab kev ua tau zoo ntawm cov nplaum pobzeb, ua rau cov nplaum sib xws dua thaum sib tov thiab txo cov teeb meem kev tsim kho uas tshwm sim los ntawm kev sib tov tsis sib xws. Tsis tas li ntawd, RDP kuj tseem tuaj yeem ntev lub sijhawm qhib ntawm cov nplaum pobzeb, muab sijhawm ntau rau cov neeg ua haujlwm tsim kho los kho thiab ua haujlwm, txo cov teeb meem kev tsim kho uas tshwm sim los ntawm kev kho ua ntej ntawm cov nplaum.
3. Txhim kho qhov tawg tsis kam thiab impermeability
Hauv cov nplaum pobzeb, kev tiv thaiv kab nrib pleb thiab kev tsis nkag mus yog cov cim qhia kev ua tau zoo tseem ceeb heev. Cov pobzeb ceramic feem ntau ntsib teeb meem xws li kev hloov pauv kub, kev hloov pauv av noo, thiab kev nkag mus rau hauv cov chaw xws li phab ntsa sab nraud, chav dej, thiab chav ua noj. Kev ntxiv RDP tuaj yeem ua rau muaj kev tiv thaiv kab nrib pleb thiab kev tsis nkag mus rau hauv cov nplaum pobzeb ceramic. Kev tsim cov zaj duab xis polymer ua haujlwm ua lub buffer ywj pheej ntawm cov pobzeb thiab cov substrate, nqus cov kev ntxhov siab sab nraud thiab tiv thaiv kev tawg. Tsis tas li ntawd, RDP zaj duab xis polymer kuj muaj kev ua tau zoo tiv thaiv dej, uas tuaj yeem tiv thaiv kev nkag mus ntawm cov dej noo thiab tiv thaiv cov substrate los ntawm kev yaig dej noo.
4. Txhim kho kev tiv thaiv huab cua thiab kev ua haujlwm ntev
Thaum siv ntev, cov nplaum pobzeb yuav tsum tiv taus kev sim ib puag ncig, xws li ultraviolet radiation, acid rain erosion, kev hloov pauv ntawm kub thiab txias, thiab lwm yam. Cov yam no yuav muaj feem cuam tshuam rau qhov ruaj khov ntawm cov nplaum. RDP tuaj yeem txhim kho qhov tiv taus huab cua thiab ruaj khov ntawm cov nplaum pobzeb ceramic. Tom qab cov nplaum kho, cov zaj duab xis polymer tuaj yeem tiv taus ultraviolet radiation thiab txo qhov puas tsuaj los ntawm ultraviolet rays. Nws kuj tseem tuaj yeem tiv taus acid thiab alkali erosion thiab ntev lub neej kev pabcuam ntawm cov nplaum. Tsis tas li ntawd, RDP kuj tseem tuaj yeem txhim kho qhov tsis kam ntawm cov nplaum rau cov voj voog khov-thaw, ua rau nws tswj tau qhov kev ua tau zoo hauv huab cua txias.
5. Txo qhov ntsws thiab txhim kho qhov yooj ywm
Cov nplaum pobzeb uas siv cov cement ib txwm muaj feem yuav ntsws thaum lub sijhawm kho, ua rau muaj kev ntxhov siab hauv txheej sib txuas, uas ua rau cov pobzeb poob lossis lub substrate puas tsuaj. Kev ntxiv RDP tuaj yeem txo qhov teeb meem ntsws no. Lub luag haujlwm ntawm RDP hauv cov nplaum zoo ib yam li cov plasticizer. Nws tuaj yeem muab qee qib ntawm kev ywj pheej rau cov nplaum, txo qhov kev ntxhov siab, thiab txhim kho kev ruaj khov ntawm txheej sib txuas, yog li tiv thaiv kev ua tsis tiav ntawm kev sib txuas vim kev ntsws.
6. Txo cov nqi siv thiab cov txiaj ntsig ntawm kev tiv thaiv ib puag ncig
Txawm hais tias RDP, ua ib yam khoom siv ntxiv uas muaj kev ua tau zoo heev, yuav ua rau tus nqi ntawm cov nplaum pobzeb nce ntxiv, tab sis kev txhim kho kev ua tau zoo thiab kev yooj yim ntawm kev tsim kho uas nws coj los tuaj yeem txo tus nqi tag nrho ntawm kev tsim kho. RDP tuaj yeem txo cov lej ntawm kev ua haujlwm dua thiab cov khoom pov tseg, thaum lub sijhawm ntev dua ntawm cov vuas ceramic thiab txo cov nqi txij nkawm. Tsis tas li ntawd, RDP nws tus kheej yog cov khoom siv zoo rau ib puag ncig uas tsis muaj cov organic sib xyaw ua ke (VOCs), tsis tso cov pa phem thaum lub sijhawm tsim kho thiab siv, thiab zoo dua rau ib puag ncig thiab tib neeg kev noj qab haus huv.
RDP ua lub luag haujlwm tseem ceeb hauv cov nplaum pobzeb. Nws muaj kev ua tau zoo los ntawm kev txhim kho lub zog sib txuas, txhim kho kev ua haujlwm ntawm kev tsim kho, txhim kho kev tiv thaiv kab nrib pleb thiab kev tsis nkag, txhim kho kev tiv thaiv huab cua thiab kev ruaj khov, txo qhov ntsws thiab txhim kho kev ywj pheej. Txhim kho qhov zoo ntawm cov nplaum pobzeb. Txawm hais tias kev ntxiv RDP yuav ua rau cov nqi khoom siv ntau ntxiv, kev txhim kho kev ua tau zoo thiab kev tiv thaiv ib puag ncig uas nws coj los ua rau nws yog qhov tseem ceeb thiab tseem ceeb ntxiv rau hauv kev tsim kho vaj tse niaj hnub.
