Sand-muaj pos huab siv MasterSeal asphalt concentrated cover khoom. MasterSeal asphalt-based concentrated cover khoom yog ib txoj kev npog cov ntaub ntawv uas muaj cov av nplaum thiab emulsified asphalt, thiab tshwj xeeb surfactants tau ntxiv los ua super muaj zog sib txuas muaj peev xwm thiab kav ntev. Aggregates raug ntxiv rau ntawm qhov chaw tsim kho los tsim cov txheej txheem uas tsis yog-slip. Nws yog cov khoom siv zoo tshaj plaws tshwj xeeb siv los tiv thaiv thiab ua kom zoo nkauj asphalt pavements. MasterSeal asphalt concentrated cover khoom yog ib qho zoo heev asphalt pavement tu cov ntaub ntawv. Nws tuaj yeem ua tiav qhov pib me me ntawm cov kab nrib pleb uas tshwm sim los ntawm nag yaig, roj thiab cov daus melting tus neeg sawv cev corrosion, thiab lub tsheb dhau, thiab nkag mus tob rau hauv cov kab nrib pleb ntawm txoj kev taug kev los tiv thaiv cov kab nrib pleb los ntawm kev nthuav dav ntxiv. Nyob rau hauv tus txheej txheem ntawm kev sau cov kab nrib pleb no, nws tsis tuaj yeem ua tau zoo ntxiv cov roj matrix ntawm pavement asphalt thiab qhib cov asphalt molecules hnyav hnyav, txo cov qib hardening ntawm txoj kev pavement, tab sis kuj daws tau ntau yam kab mob tshwm sim los ntawm kev poob ntawm asphalt. Nws yog tsuas yog siv rau kev kho kom zoo nkauj thiab kev saib xyuas ntawm asphalt pavements, xws li chaw nres tsheb, tshav dav hlau, kev tsav tsheb, khw malls, txoj kev, thiab lwm yam.

Cov yam ntxwv ntawm cov xuab zeb uas muaj pos huab
Nws yog tshwj xeeb tshaj yog haum rau siv nyob rau hauv thaum ntxov theem ntawm pavement lub neej. Nws tuaj yeem ncua qhov tshwm sim thiab kev loj hlob ntawm cov kab mob pavement thiab tswj cov kev pabcuam zoo ntawm txoj kev pavement ntawm tus nqi kho tus nqi qis. Nws yog qhov tshwj xeeb tshaj yog rau cov qib siab lossis lwm txoj kev tsim kho tshiab uas tau qhib rau kev khiav tsheb rau 2-3 xyoos thiab tsis muaj kab mob pom tseeb.
2. Nws kuj tseem siv tau rau cov pavements nrog kev laus asphalt hnyav. Nws tuaj yeem txhim kho cov hnub nyoog asphalt ntawm txoj kev taug kev los ntawm nws tus kheej txo qis thiab rov tsim cov yam ntxwv, thiab txhim kho qhov pom ntawm txoj kev pavement.
3. Kev tiv thaiv dej kom zoo thiab txhim kho kev tiv thaiv kev ua haujlwm ntawm txoj kev pavement: xuab zeb ntawm qhov tsim nyog particle loj yog sib tov sib npaug nrog tus neeg saib xyuas txo thiab txau rau ntawm txoj kev ntawm kev kub siab. Nws muaj qhov zoo ntawm kev txo tus neeg sawv cev foob thiab pos huab, thiab ua rau qhov tsis zoo ntawm kev ua haujlwm tsis zoo los tiv thaiv kev ua haujlwm ntawm cov pos huab dav dav, ua kom muaj kev nyab xeeb ntawm kev tsav tsheb.
Dab tsi yog qhov cuam tshuam ntawm cov xuab zeb uas muaj pos huab?
Nws muaj permeability, uas tuaj yeem tiv thaiv qhov loosening ntawm cov ntaub ntawv crushed los yog poob ntawm nplua xuab zeb thiab gravel. Nws muaj dej tsis kam thiab tiv taus permeability rau cov roj av sib xyaw, tshuaj tiv thaiv kab mob, thiab lwm yam. Nws tsis yooj yim rau tawg los yog tev tawm, thiab muaj viscosity siab, ductility thiab durability. Nws tuaj yeem kho qhov kev ua tau zoo ntawm asphalt thiab txuas ntxiv nws txoj haujlwm zoo. Nws tuaj yeem txo cov nqi txij nkawm txhua xyoo thiab ua kom zoo nkauj ntawm txoj kev, thiab txhim kho qhov pom ntawm cov paib thiab cov cim ntawm kev khiav, txoj kev loj thiab chaw nres tsheb. Kev tsim kho yog yooj yim thiab ceev, thiab lub sijhawm nws qhib rau kev khiav tsheb yog luv.
