Lub tshuab ntawm kev ua ntawm recispersible polymer hmoov (RDP) hauv cov tshuaj khib qhuav

Redispersible polymer hmoov (RDP)Yog ib qho tseem ceeb ntxiv rau hauv cov kab cug qhuav, muab ntau cov txiaj ntsig xws li txhim kho adhesion, cohesion, yooj yim, thiab kev ua haujlwm. Nws cov tshuab kev nqis tes cuam tshuam nrog ntau theem, los ntawm kev dispersion hauv dej los cuam tshuam nrog lwm cov hauv cov tshuaj khib. Cia relve rau hauv cov ncauj lus kom ntxaws:

Dispersion hauv dej:
RDP hais yog tsim los disperse sai thiab uniformly nyob rau hauv dej vim lawv hydrophilic xwm. Thaum ntawd ntawm cov dej tshuaj sib tov rau cov tshuaj khib nyiab qhuav, cov khoom noj nrog cov khoom tawg thiab tawg, sib sau ua ke ruaj khov. Qhov kev rho tawm no nthuav tawm thaj chaw loj ntawm cov polymer rau ib puag ncig ib puag ncig, pab txhawb kev sib cuam tshuam ntxiv.

Zaj duab xis tsim:
Raws li cov dej txuas ntxiv mus ua kom haum rau hauv cov tshuaj khib, cov dispersed RDP hais pib ncig ua yeeb yaj kiab ib ncig ntawm cov xis nyob ib ncig ntawm cov khoom noj kom zoo nkauj thiab lwm cov txheej txheem. Zaj yeeb yaj kiab no ua qhov thaiv kev, tiv thaiv kev sib cuag ncaj qha ntawm cov khoom siv xis thiab kev noo noo. Qhov no yog qhov tseem ceeb rau kev txo dej ingress, txhim kho durability, thiab txo qis kev pheej hmoo ntawm efforescence thiab lwm hom kev ua tsis raws cai.

Txhim kho adhesion thiab cohesion:
Cov yeeb yaj kiab polymer tsim los ntawm RDP pabcuam ua tus neeg sawv cev ua qhev, txhawb nqa cov tshuaj khib nyiab thiab ntau yam kev ua yeeb yam, masonry, lossis cov vuas. Cov yeeb yaj kiab tseem txhim kho cov cohesion nyob rau hauv lub cug lub matrix los ntawm bridging cov khoob ntawm cov khoom siv zog, yog li txhim kho lub zog tag nrho thiab kev ncaj ncees ntawm lub plhaw cug.

Yooj taus thiab tawg tsis kam:
Ib qho ntawm cov ntsiab lus tseem ceeb ntawm RDP yog nws lub peev xwm los ua kom haum rau lub tshuaj khib matrix. Cov yeeb yaj kiab polymer ua kom haum siv Minetrate txav thiab thermal nthuav dav, txo txoj kev pheej hmoo ntawm kev tawg. Tsis tas li ntawd, DPP txhim kho lub zog tensile thiab duction ntawm lub cug, txuas ntxiv txhim kho nws txoj kev tiv thaiv kom tawg nyob rau hauv ob qho tib si zoo li qub thiab muaj zog.

Dej khaws cia:
Lub xub ntiag ntawm RDP nyob rau hauv lub cug sib xyaw pab tswj kav dej, tiv thaiv kev tiv thaiv nrawm nrawm thaum pib thaum ntxov ntawm kev kho. Qhov no ncua cov dej hydration hydration ua tiav txoj kev hloov kom zoo thiab ua kom muaj kev cuam tshuam zoo dua qub ntawm cov khoom siv mechanical, xws li lub zog compressive thiab yooj yim dua. Ntxiv mus, cov dej tswj kav dej ua kom tau zoo dua li kev txhim kho lub sijhawm ua haujlwm thiab lub sijhawm qhib lub sijhawm, yooj yim ntawm cov tshuaj khib.

Durability Ehhancement:
Los ntawm kev txhim kho adhesion, yooj yim, thiab kev tiv thaiv kom tawg, DPP tseem ua qhov tsis muaj zog ntawm cov tshuaj khib. Cov yeeb yaj kiab polymer ua raws li kev tiv thaiv kev tiv thaiv kev tua hluav taws, yog ib puag ncig kev ua haujlwm ntawm lub neej ntawm lub tshuaj khib thiab txo cov kev saib xyuas.

Sib cav nrog cov quav ntxiv:
RdpCov khoom ua pov thawj zoo tau sib xws nrog ntau yam ntxiv siv rau hauv cov tshuaj ntxiv rau hauv cov khoom siv qhuav, cov khoom siv roj av, retarders, thiab pigments. Cov versatility no tso cai rau kev coltization ntawm cug lub culture kom tau raws li cov kev ua tau zoo rau kev siv rau cov ntawv thov sib txawv thiab ib puag ncig.

Lub tshuab ntawm kev ua ntawm dispersible polymer hmoov hauv cov tshuaj khib nyiab thiab kev ua yeeb yam, ua kom muaj zog, ua kom muaj zog, ua kom haum nrog cov quav ntxiv. Cov teebmeem kev sib xyaw ua ke ua rau kev ua tau zoo, ua haujlwm, thiab kav dej ntshiab ntawm cov kev siv kev siv.
