Dab tsi yog txoj kev uas muaj kev sib tsoo ntawm kev sib tsoo? Muaj pes tsawg leeg, elasticity & huab cua tiv thaiv tau piav qhia
Txoj kev ntxuam Sealant yog cov khoom tshwj xeeb siv los kho thiab ntim cov kab nrib pleb hauv asphalt lossis qhob cov chaw. Nws tiv thaiv dej, khib nyiab, thiab tshuaj lom neeg los ntawm infiltrating cov qauv kev cai, uas tuaj yeem ua rau potholes, puag-txheej yaig, thiab kev tsim kho muaj nuj nqis.
Muaj pes tsawg
Nrov cov foob pob hluav taws xob feem ntau muaj ntawm:
Puag asphalt: muab cov khoom nplaum nplaum thiab dej tsis muaj dej.
Polymers: xws li SBS (Styrene-Butadiene-Styrene) lossis SBR (Styrene-Butadiene roj hmab), txhim kho elasticity thiab tsev neeg muaj zog.
Cov roj hmab ntxiv: nrog rau cov roj hmab crumb, resins, antioxidants, thiab UV stabilizers rau boost durability thiab huab cua tsis kam.
Fillers: Zoo li limestone lossis quartz xuab zeb, txhim kho kev ruaj khov thiab nqi ua haujlwm.
Elastic
Cov sealants yuav tsum muaj qhov tseeb (≥ 50% rov qab tus nqi) kom haum kev kev tsiv ntawm kev txav mus los ntawm kev hloov tsheb thiab thauj khoom. Piv txwv li, lawv tuaj yeem ncab ntau dua 100 cm yam tsis muaj kev tawg ntawm tsawg kub (-20 ° C), ua kom muaj kev tiv thaiv ntev.
Huab Cua Kuj
Thaum tshav kub kub ua: withstands kub txog 80-110 ° C tsis softening lossis ntws.
Txias yooj tseg: tseem pliable ntawm -20 ° C rau -40 ° C, zam brittle unactures.
Kev tiv thaiv kev laus: UV nqus thiab cov antioxidant txo qis ntawm tshav ntuj, oxygen, thiab noo noo, lub neej pabcuam kev pabcuam ntxiv.
Cov Ntawv Thov
Siv rau ntawm txoj kev loj, tshav dav hlau, thiab chaw nres tsheb, tsoo cov xov xwm, thiab siv cov tape-adhesive tapes rau kev kho sai. Lawv qhov kev siv protantenses ncua ntev lifes lifespan los ntawm 5-7 xyoo, txo cov nqi txij li li 75% piv rau kev kho kom zoo.
Hauv cov ntsiab lus, tawg cov sealants sib txuas ua ke cov kws kho tshuab thiab kev tsim kho kom tiv thaiv cov tsheb loj los ntawm kev hloov chaw, huab cua kev sib khi.
