Cov txiaj ntsig ntawm kev siv RDP

Txhim kho kev ua haujlwm

RDP nce kev ua haujlwm ntawm cov khoom siv hauv tsev, ua kom yooj yim rau kev sib xyaw, thov thiab siv. Qhov no txo ​​cov nqi zog thiab ua kom muaj txiaj ntsig ntawm cov chaw tsim kho. RDP txhim kho cov khoom ntws, slump thiab kis tau. Qhov kawg tshwm sim yog ib yam khoom kawg nkaus. Tsis tas li ntawd, nws tiv thaiv kev sib cais thiab seepage ntawm cov ntaub ntawv thaum lub sij hawm thauj mus los thiab muab tso rau.

txhim khu adhesion

Kev siv RDP hauv cov ntaub ntawv tsim kho muaj txiaj ntsig zoo vim nws txhim kho qhov adhesion ntawm cov khoom no. RDP tsim kev sib raug zoo ntawm cov khoom thiab substrate. Cov khoom no txhim khu cov khoom tiv thaiv rau delamination, cracking thiab spalling. Yog li, nws yuav ua rau cov khoom siv tau ntev dua thiab kav ntev. RDP txhim khu cov adhesion ntawm lub tsev cov ntaub ntawv rau substrates xws li pob zeb, ntoo thiab hlau.

nce dej tsis kam

RDP nce dej tsis kam los ntawm kev tsim ib qho kev thaiv hydrophobic uas tiv thaiv dej. Qhov no yog qhov tshwj xeeb tshaj yog rau cov ntaub ntawv raug dej, xws li facades, ru tsev thiab hauv pem teb. Tshwj xeeb tshaj yog tseem ceeb rau cov ntaub ntawv raug dej xws li facades, ru tsev thiab pem teb. RDP nce dej tsis kam thiab tiv thaiv kev puas tsuaj ntawm cov dej noo. Piv txwv li, pwm loj hlob, tawg thiab corrosion.

zoo dua khov-thaw kuj

RDP nce qhov khov-thaw tsis kam ntawm cov khoom siv hauv tsev los ntawm kev txhim kho lawv lub peev xwm los tiv thaiv lub voj voog khov-thaw. Cov nyhuv no yog qhov tseem ceeb rau cov ntaub ntawv raug huab cua txias. Piv txwv li, txoj kev pej xeem, choj, thiab kev taug kev. Ntxiv RDP tiv thaiv cov khoom puas, tawg thiab tev. Thaum kawg, tus nqi kho yuav raug txo.

Txhim kho yooj

RDP nce qhov yooj ntawm cov khoom siv los ntawm kev ua kom lawv elasticity thiab ductility. Qhov no yog qhov tseem ceeb tshwj xeeb tshaj yog rau cov ntaub ntawv raug kev ntxhov siab. Txij li thaum nws txhim kho qhov hloov pauv ntawm cov khoom siv, nws tuaj yeem tiv thaiv cov khoom tsis zoo. Piv txwv li, nws tiv thaiv cov plag tsev thiab phab ntsa los ntawm kev tawg thiab warping. Qhov txiaj ntsig no thaum kawg txhim kho cov khoom muaj peev xwm nqus kev co thiab poob siab.

nce zog

RDP hmoov nce lub zog ntawm cov khoom siv hauv tsev. Qhov no suav nrog lawv cov compressive, tensile thiab flexural zog. Qhov no yog qhov tseem ceeb tshwj xeeb tshaj yog rau cov khoom siv hnyav, xws li txuas hniav, vaj tse thiab pavements. Ntxiv nrog rau kev tiv thaiv kev tawg thiab tawg, kev ua kom lub zog yuav ua rau kom muaj zog ntawm cov khoom siv.

Txhim khu durability

RDP txhim khu kev ruaj khov ntawm cov khoom siv hauv tsev los ntawm kev txhim kho lawv cov kev tiv thaiv rau kev puas tsuaj, cuam tshuam thiab tshuaj tua kab mob. Yog li ntawd, qhov no yog qhov tseem ceeb rau cov ntaub ntawv raug rau ib puag ncig hnyav. Piv txwv li, pej xeem txoj kev, choj thiab tunnels. Ua kom durability ncua lub neej ntawm cov khoom. Zuag qhia tag nrho, kev siv RDP tuaj yeem txhim kho cov tsos thiab lub neej ntawm cov ntaub ntawv.

txo shrinkage

RDP txo qis cov khoom siv hauv tsev los ntawm kev txhim kho lawv lub peev xwm tuav dej. Cov cuab yeej no tseem ceeb tshwj xeeb tshaj yog rau cov ntaub ntawv raug rau qhov chaw qhuav. Txo shrinkage tiv thaiv cov khoom los ntawm cracking thiab deforming. Li no txhim kho qhov seem stability ntawm cov khoom.

Sustainable

RDP yog cov khoom siv ruaj khov uas txo cov kev cuam tshuam ib puag ncig ntawm kev coj ua hauv tsev. RDP yog tsim los ntawm ntuj thiab hluavtaws polymers thiab tuaj yeem tsim tau siv cov txheej txheem ib puag ncig. Nws siv tuaj yeem txo qhov cuam tshuam ntawm ib puag ncig muaj kuab paug thaum lub sijhawm tsim kho.

Nqi-zoo

RDP yog cov khoom siv tau zoo uas tuaj yeem txo cov nqi tsim kho tag nrho. RDP hmoov txhim kho cov khoom siv hauv tsev. Nws txo qis qhov xav tau ntawm kev ua haujlwm ntxiv thiab khoom siv. Qhov no txuag cov nqi rau cov neeg cog lus thiab cov tswv qhov project. Tsis tas li ntawd, RDP txo qhov kev xav tau ntawm kev saib xyuas thiab kho ntau zaus, ua rau kev txuag nyiaj mus sij hawm ntev.

Zuag qhia tag nrho, RDP yog cov khoom siv tshiab uas coj tau ntau yam txiaj ntsig rau kev tsim kho kom ruaj khov. Nyob rau tib lub sijhawm, nws txo qhov cuam tshuam ib puag ncig ntawm shrinkage thiab kev tsim kho. Tsis tas li ntawd, RDP yog cov khoom siv tau zoo uas txo cov nqi tsim kho.

Zuag qhia tag nrho, siv RDP tuaj yeem pab tsim cov haujlwm ruaj khov thiab siv tau ntev. Qhov no tuaj yeem pab tau cov tsev zoo dua rau cov kev cov nyom ntawm ib puag ncig hnyav. Los ntawm kev ua kom zoo dua ntawm RDP, cov neeg cog lus tuaj yeem txo cov nqi thiab kev pheej hmoo cuam tshuam nrog kev tsim kho. Tsis tas li ntawd, nws tuaj yeem pab txhawb rau yav tom ntej.
