PMB 70
Nkag siab Bitumen PMB 70
Bitumen PMB 70, tseem hu ua Polymer Hloov Bitumen , yog ib qho tshwj xeeb tsim cov khoom siv bituminous uas ua ke nrog bitumen nrog polymers los txhim kho nws cov kev ua tau zoo thiab kav ntev. "70" qhia txog nws qib nkag mus, qhia nws cov viscosity thiab sib xws raws li cov xwm txheej tshwj xeeb. Cov qib tshwj xeeb no muaj qhov sib npaug ntawm cov khoom tsim nyog rau ntau yam siv tej yaam num.
Daim ntawv thov ntawm PMB Bitumen
Lub versatility ua rau nws nyiam xaiv nyob rau hauv ntau yam kev siv nyob rau hauv kev tsim kho kev lag luam. Nws yog feem ntau siv nyob rau hauv txoj kev tsim kho, muab superior tiv thaiv rutting, ntes, thiab deformation. Tsis tas li ntawd, Nws pom kev siv hluav taws xob hauv tshav dav hlau pavements, choj decks, thiab cheeb tsam nrog tsheb loj, qhov twg nws cov durability thiab ntev lub neej muaj nuj nqis heev.
Kev Ntsuas Sib Piv: PMB 70 vs lwm Qib
Thaum koj muab piv rau lwm hom bitumen xws li PMB 140 lossis Benrfit, koj tuaj yeem pom qhov sib txawv ntawm qhov nws ua tau zoo thiab nws zoo li cas. Hom no bitumen muaj ib tug nruab nrab ntawm cov polymer nyob rau hauv nws, uas txhais tau hais tias nws tsis dhau saj zawg zog los yog nruj heev. Qhov no ua rau nws zoo rau ntau hom huab cua. Nws yog ib qho tseem ceeb kom nkag siab txog qhov sib txawv no yog li koj tuaj yeem xaiv qhov zoo ntawm bitumen rau koj qhov kev xav tau tshwj xeeb.
Nqe ntawm Asphalt Polymer Hloov Bitumen
Tus nqi yog cuam tshuam los ntawm ntau yam, suav nrog 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. Tiv tauj peb rau kev txheeb xyuas tus nqi tsim nyog thiab cov tswv yim kev yuav khoom uas tuaj yeem txhim kho kev siv cov khoom hauv qhov project pob nyiaj siv
Cov kev coj ua zoo tshaj plaws hauv kev tuav thiab khaws cia
Pib tuav thiab kev coj noj coj ua yog qhov tseem ceeb rau kev khaws cia zoo thiab cov khoom ntawm cov khoom. Cov khoom siv yuav tsum tau muab khaws cia rau hauv ib puag ncig tswj, kom deb ntawm tshav ntuj ncaj qha thiab noo noo, tiv thaiv kev degradation thiab tswj nws cov yam ntxwv ua haujlwm. Kev ntim khoom kom zoo, xws li cov ntim ntim ntim lossis lub nruas, ntxiv kom muaj kev ncaj ncees thaum thauj thiab khaws cia.
