Tom ntej: Bitumen SC250
Introduction
Tom ntej: Bitumen SC250 yog hom ntawm asphalt cement uas suav nrog cov kuab tshuaj los yog distillate, xws li roj av lossis roj av, kom ua tiav cov dej ntws ntawm qhov kub thiab txias. Sib tham txog nws cov yam ntxwv, kev siv, kev tsim khoom, thiab kev saib xyuas kev nyab xeeb ntawm SC-250 cutback bitumen.
Cov khoom ntawm Cutback Bitumen SC250
Cutback asphalt nrog SC-250 tus qauv feem ntau muaj nyob nruab nrab ntawm 12 thiab 40 feem pua ​​​​ntawm distillate. Cov ntsiab lus distillate no cuam tshuam nws viscosity thiab cov yam ntxwv ntawm daim ntawv thov, ua rau nws haum rau ntau yam kev tsim kho, tshwj xeeb tshaj yog nyob rau hauv txoj kev surfacing thiab waterproofing.
Kev tsim cov txheej txheem ntawm SC-250 Bitumen
Kev tsim tawm ntawm SC-250 cutback bitumen cuam tshuam nrog kev ua haujlwm asphalt cement nrog cov tsis muaj zog distillate, xws li roj av. Cov txheej txheem no tsim cov ntaub ntawv zoo ib yam li cov roj hnyav hnyav siv hauv cov ntawv thov kev lag luam. SC-250 qib cutback bitumen feem ntau siv hauv txoj kev kev tsim kho vim nws yooj yim daim ntawv thov thiab adhesion zog.
Kev siv Asphalt SC-250
SC-250 cutback bitumen pom kev siv dav hauv kev nkag mus rau hauv cov tsho loj, qhov uas nws pab hauv kev npaj thiab adhesion. Tsis tas li ntawd, nws yog koom ua ke rau hauv patching thiab stockpile mixs, txhim kho cov txheej txheej ntawm cov khoom sib sau ua ke thiab ua kom ruaj khov. Nws waterproofing muaj peev xwm ua rau nws zoo tagnrho rau kev sib khi ntawm qhov chaw thiab kev sib txuas cov ntxhia pob zeb.
Packing and Safety Measures
Cutback bitumen SC-250 feem ntau yog ntim rau hauv cov tshiab, tuab steel nruas ntawm pallets los tiv thaiv kom tsis txhob xau thaum thauj thiab khaws cia. Kev ceev faj txog kev nyab xeeb suav nrog kev xa mus rau Cov Ntawv Pov Thawj Kev Nyab Xeeb (SDS) ua ntej siv, zam qhov tsis muaj hluav taws xob, hnav cov khoom tiv thaiv tus kheej tsim nyog (PPE), thiab tiv thaiv cov khoom sib cuag nrog cov tawv nqaij lossis nkag mus rau hauv cov dej.
