Bitumen PG 70/22
Introduction
Bitumen PG 70/22, renowned rau nws versatility thiab kev ntseeg tau, yog ib tug paving-qib bitumen uas tuav cov lus cog tseg loj heev hauv ntau daim ntawv thov kev tsim kho. Los ntawm txoj kev kev tsim kho rau cov phiaj xwm infrastructure, nws cov khoom ua rau nws muaj txiaj ntsig zoo hauv kev lag luam.
Nkag siab PG 70/22
Asphalt PG 70/22 yog tus cwj pwm los ntawm nws qib nkag ntawm 70 thiab qhov kub thiab txias ntawm 22, ua rau nws haum rau ntau yam huab cua thiab tej yam kev mob.
Kev siv hauv kev tsim kho
Hauv kev tsim kho txoj kev, Nws yog qhov tsis tseem ceeb, ua haujlwm tseem ceeb hauv asphalt sib tov. Nws cov khoom zoo heev adhesion kom ruaj khov ntawm txoj kev muaj peev xwm tiv taus cov tsheb thauj khoom hnyav.
Txhim kho Asphalt Mixtures
Kev suav nrog Bitumen PG 70/22 nyob rau hauv asphalt sib tov ua tau zoo txhim kho kev ua tau zoo, txhim khu kev tiv thaiv rutting thiab tawg, ua rau txoj kev smoother thiab kev nyab xeeb.
Cov txiaj ntsig hauv Pavement Durability
Nws contributes rau tag nrho durability ntawm pavements, ua kom lub neej ntev thiab txo qhov xav tau ntawm kev tu thiab kho tsis tu ncua.
Environmental Sustainability
Los ntawm ib puag ncig ib puag ncig, Bitumen PG 70/22 muaj qhov zoo tshaj plaws, muab cov kev daws teeb meem ruaj khov rau kev tsim kho thiab txo cov pa roj carbon hneev taw cuam tshuam nrog kev saib xyuas cov haujlwm.
Quality Assurance thiab Specifications
Nws dhau los ua cov txheej txheem kev ruaj ntseg zoo kom ua raws li cov qauv kev lag luam, lav kev ua tau zoo thiab kev ntseeg tau.
Nqe thiab ntim
Tus nqi ntawm Bitumen PG 70/22 yuav txawv nyob ntawm seb yam xws li kev xav tau ntawm kev lag luam thiab cov khoom muaj nyob. Kev ntim khoom feem ntau yog ua los ntawm kev lag luam-txheej txheem ntim lossis nruas, ua kom muaj kev tiv thaiv los ntawm kev sib kis thiab tswj cov khoom ncaj ncees thaum khaws cia thiab kev thauj mus los.
