Qhov kev kawm txuj ci tom qab cov kev foob kev taug kev hauv txoj kev: Yuav ua li cas lawv txuas txoj kev pua
Txoj kev sealants yog cov txheej txheem ua haujlwm ua kom zoo li "tso tshuaj pleev thaiv hnub" rau asphalt, tiv thaiv nws ntawm ib puag ncig nws lifespy los ntawm 5-10 xyoo. Nov yog lawv ua haujlwm li cas:
Cov Cheebtsam Tseem Ceeb & Ua Haujlwm
Cov sealants sib sau ua ke tawm me me emulsion (asphalt / thee filleters (av nplaum, xuab zeb), thiab ntxiv), looj). Thaum thov:
Bitumen ua cov dej tsis muaj dej thaiv, thaiv cov dej noo Interiltration uas ua rau khov-yaj cov kab nrib pleb thiab potholes.
Cov pob zeb hauv av sau sau saum nplaim av thiab cov micro-nrum, rov ua cov txheej txheem kev ntseeg siab thiab txhim kho comid kuj.
Polymer Additives txhim kho kev hloov pauv tau yooj yim, tso cai rau kev sib cog lus los nthuav tawm / Daim Ntawv Cog Lus nrog qhov kub hloov yam tsis muaj kev tawg.
Kev thaiv kev tawm tsam kev ua txhaum
UV Yaus: Sealant Koom ua ke ntawm asphalt tus nqi los ntawm oxidizing thiab ua brittic nyob rau hauv tshav ntuj, txo kev tawg los ntawm> 90%.
Tshuaj tiv thaiv tshuaj: lawv tiv taus cov roj, roj, thiab de-icing ntsev uas tshem tawm ntawm Aspers, khaws cov pavav pavers binders, khaws cov pavement binders, khaws cov kev ua vaj tse ua kom yooj yim.
Dej reprelency: los ntawm kev sib khi saum npoo av, lawv thaiv cov dej nkag mus - ib qho tseem ceeb ua rau lub hauv paus-txheej yaig erosion thiab tog.
Ntev & Nqi Muaj Peev Xwm
Lub Neej Txuas Ntxiv: Kev sib khi tsis tu ncua txhua 2-3 xyoos tuaj yeem ncua kev ua kom txog li 30 xyoo, zam kev rov tsim kho tus nqi.
Economic Kev Koom Tes: Ntim cov nqi siv 0.15-0.35 / sq ft, tab sis kho rau unsealed asphalt tau ncav cuag $ 1.50 / sq ft.
Kev Tsim Kho & Kev Loj Hlob
Niaj hnub nimno foob xws li asphalt emulsions (vs. thee tar) thiab polyurethane sealant muaj eco-friendly, siab-zoo-hloov cov kev daws teeb meem. Lawv teeb tsa cov khoom siv ua rov qab (piv txwv li, roj hmab crack) thiab kho kom sai (<12 teev), txo txoj kev kaw.
Tseem ceeb takeway: txoj kev sealwant: kev tshawb fawb txog kev tshawb fawb-sib xyaw ua ke, thiab kev nyab xeeb los tiv thaiv cov tsiaj los ntawm kev hnav thiab lub kua muag.
