Bitumen PMB 50
Bitumen PMB 40 yog dab tsi
Bitumen PMB 40, tseem hu ua Polymer Modified Bitumen 40, yog cov khoom siv tshwj xeeb bituminous engineered los txhim kho nws cov kev ua tau zoo thiab kav ntev los ntawm cov khoom siv polymer. Qib no tus nqi nkag mus ntawm 40 qhia nws qhov viscosity thiab sib xws raws li cov xwm txheej tau teev tseg, ua rau nws haum rau ntau yam. siv daim ntaub ntawv.
Kev Ntsuas Sib Piv: PMB 40 vs. Lwm Qib
Thaum muab piv nrog lwm tus bitumen Cov qib, xws li qib nkag siab dua lossis cov qauv tsim tshwj xeeb, qhov sib txawv sib txawv tshwm sim raws li kev ua tau zoo thiab tsim nyog rau ib puag ncig tshwj xeeb. Nws muaj ib tug balanced ua ke ntawm viscosity thiab hloov tau yooj yim, ua rau nws haum rau thaj chaw tsheb nruab nrab thiab thaj chaw uas muaj kev sib txawv huab cua tej yam kev mob.
Kev siv ntawm PMB 40
Nws yog ib qho khoom muaj nqis hauv kev tsim kho vaj tse. Nws yog feem ntau siv hauv kev tsim kho kev txhim kho tsis kam mus rutting, tawg, thiab kev laus, ua rau ntev-ntev thiab ruaj khov ntawm txoj kev. Tsis tas li ntawd, Nws pom cov ntawv thov hauv tshav dav hlau pavements, choj decks, thiab thaj chaw uas muaj tsheb loj vim nws cov yam ntxwv ua tau zoo.
Nqe Dynamics thiab Affordability
Tus nqi ntawm PMB yog cuam tshuam los ntawm cov khoom xws li cov nqi raw khoom, kev xav tau ntawm kev lag luam, thiab kev nce qib thev naus laus zis. Txawm hais tias nws yuav raug nqi sib tw piv rau qib siab PMBs, tus nqi pheej yig ntawm PMB 40 nyob rau hauv nws cov txiaj ntsig kev ua tau zoo thiab tsim nyog rau ntau yam. siv tej yaam num. Tiv tauj peb rau kev txheeb xyuas tus nqi tsim nyog thiab cov tswv yim kev yuav khoom tuaj yeem txhim kho nws txoj kev siv nyob rau hauv kev txwv nyiaj txiag.
Cov kev coj ua zoo tshaj plaws hauv kev tuav thiab khaws cia
Kev tuav thiab khaws cia kom zoo yog qhov tseem ceeb los tswj nws qhov zoo thiab kev ua haujlwm zoo. Nws yuav tsum tau muab khaws cia rau hauv qhov chaw tswj hwm, tiv thaiv los ntawm tshav ntuj ncaj qha thiab noo noo, tiv thaiv kev degradation thiab ua kom zoo sib xws thaum siv. Kev ntim khoom txaus, xws li ntim ntim lossis nruas, ntxiv rau nws cov txee lub neej thiab siv tau.
