Cov hmoov polymer uas tawg tau dua (RDP) yog ib yam khoom siv tseem ceeb hauv cov khoom siv nplaum pobzeb. Nws yog ib hom hmoov polymer uas tsim los ntawm kev txau kom qhuav cov kua roj hmab latex uas muaj dej. Nws muaj ntau yam zoo hauv kev txhim kho kev ua tau zoo ntawm cov nplaum pobzeb, xws li kev nplaum zoo dua, kev sib koom ua ke thiab kev tiv thaiv dej, thiab lwm yam. Hauv tsab xov xwm no, peb yuav los saib ze dua txog lub luag haujlwm ntawm RDP hauv kev siv nplaum pobzeb.
1. Txhim kho kev sib koom ua ke thiab kev sib txuas
Ib qho ntawm cov kev siv tseem ceeb ntawm RDP hauv kev lag luam nplaum pobzeb yog los txhim kho lub zog ntawm cov nplaum. RDP txhim kho qhov kev sib txuas ntawm cov nplaum rau ntawm qhov chaw thiab kev sib koom ua ke ntawm cov txheej nplaum. Qhov no tso cai rau kev muaj peev xwm zoo dua los tuav cov pobzeb rau hauv qhov chaw ntev dua yam tsis ua rau muaj kev puas tsuaj rau lub substrate lossis pobzeb.
2. Txhim kho kev tiv thaiv dej
Ntxiv rau kev txhim kho lub zog sib txuas, RDP kuj tseem tuaj yeem ua kom cov nplaum pobzeb tsis kam dej. Thaum sib xyaw nrog cement, RDP txo qhov nqus dej ntawm cov nplaum, ua rau nws zoo tagnrho rau cov chaw uas raug dej noo ntau. Nws ua kom cov nplaum tsis kam dej nkag mus, yog li txo qhov kev pheej hmoo ntawm cov pobzeb tawg thiab puas tsuaj rau lub substrate.
3. Txhim kho kev ywj pheej
Cov nplaum rau pobzeb yooj yim puas tsuaj los ntawm kev hloov pauv kub, kev co thiab lwm yam sab nraud. Cov hmoov latex uas yaj tau dua ua rau cov nplaum muaj kev ywj pheej thiab kev ywj pheej zoo dua, txo qhov kev pheej hmoo ntawm kev tawg thiab kev puas tsuaj. Tsis tas li ntawd, nws ua rau cov nplaum muaj peev xwm tiv taus kev hloov pauv kub thiab tiv thaiv kev ntsws, ua rau nws zoo tagnrho rau kev siv rau hauv ntau yam huab cua sib txawv.
4. Kev ua haujlwm zoo dua
Qhov ua tau yooj yim ntawm cov nplaum pobzeb yog vim lawv yooj yim siv, sib tov thiab nthuav dav. RDP txhim kho qhov ua tau yooj yim ntawm cov nplaum los ntawm kev txhim kho nws cov yam ntxwv ntws, ua rau nws yooj yim dua rau kev sib tov thiab nthuav dav. Nws kuj txo qhov sagging thiab swb ntawm cov pobzeb thaum lub sijhawm teeb tsa, muab kev sib phim zoo dua thiab txo cov khib nyiab.
5. Ua kom ruaj khov dua
Cov nplaum rau pobzeb uas muaj RDP ua tau zoo dua thiab siv tau ntev dua. Nws ua rau cov nplaum tsis yooj yim puas, cuam tshuam thiab ua rau nws zoo tagnrho rau kev siv rau hauv cov chaw muaj neeg coob lossis cov chaw thauj khoom ntau. Kev ua kom cov nplaum ruaj khov dua kuj txhais tau tias yuav tsum tau saib xyuas thiab kho tsawg dua, ua rau cov neeg siv txuag tau nyiaj.
xaus lus
Cov hmoov polymer uas tawg tau dua tshiab muaj ntau yam zoo thaum siv rau hauv cov qauv nplaum pobzeb. Nws ua rau cov nplaum muaj zog dua, tiv taus dej, yooj ywm dua, ua haujlwm tau zoo dua thiab ruaj khov dua, ua rau nws zoo tagnrho rau ntau yam kev siv. Tsis tas li ntawd xwb, nws yog ib qho kev daws teeb meem pheej yig uas muab kev ua haujlwm ntev thiab txo qhov xav tau kev kho thiab kev saib xyuas ntau zaus. Zuag qhia tag nrho, RDP tau dhau los ua ib qho khoom siv tseem ceeb hauv kev lag luam nplaum pobzeb, thiab nws qhov kev thov yuav txuas ntxiv mus rau yav tom ntej.
