Daim ntawv thov ntawm Cutback Bitumen MC70 

MC-70 bitumen, tseem hu ua MC-70 asphalt, ua raws li ib tug primer nyob rau hauv txoj kev txheej txheej txheem. Nws yog rhuab thiab txau rau ntawm txoj kev hauv paus ua ntej qhov kawg asphalt txheej yog thov. Nrog lub kinematic viscosity xws li 70 txog 140, MC-70 ua tau zoo cov tsho tiv no thiab daim ntawv cog lus loosely bonded thiab nplua-grained av zoo li cov xuab zeb zoo. Txawm li cas los xij, nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias rau cov kev kawm qib qis, MC-30 cutback bitumen yog qhov tsim nyog dua.

Tsis tas li ntawd, MC-70 Asphalt yog siv rau kev tswj cov plua plav ntawm txoj kev uas tsis tau tsim. Nws yog ib qho tseem ceeb kom nco ntsoov tias qee lub teb chaws txwv tsis pub nws siv vim muaj cov kuab tshuaj txaus ntshai nyob rau hauv cutback bitumen.

Kev tuav thiab kev siv ntawm Bitumen MC70 

Ua ntej pib ua daim ntawv thov, nws yog ib qho tseem ceeb uas yuav tau xav txog cov ntsiab lus hauv qab no:

Pom zoo Daim Ntawv Thov Kub: MC-70 yuav tsum tau thov ntawm qhov kub ntawm 50 ° C.

Npaum Npaj: Xyuas kom meej tias qhov chaw huv si ua ntej siv los ua ib lub tsho loj. Ua kom sov lub primer kom txaus rau kev txau zoo.

Kev Siv Hauv Paus Txoj Kev: Thaum siv MC-70 Asphalt rau ntawm txoj kev, tswj qhov kub ntawm qhov chaw ntawm 10 ° C thiab xyuas kom huv si kom tau txiaj ntsig zoo tshaj plaws.

Nqe thiab ntim ntawm Cutback MC-70

Thaum tsom mus rau MC-70 nkaus xwb, nws nthuav tawm cov yam ntxwv tshwj xeeb thiab kev txiav txim siab txog tus nqi, ntim khoom, thiab tuav. Nws yog lub npe hu rau nws cov nqi sib tw, ua rau nws muaj kev xaiv nyiaj txiag rau ntau yam kev tsim kho txoj kev. Hais txog kev ntim khoom, MC-70 muaj nyob rau hauv cov neeg siv kev xaiv uas yooj yim rau kev thauj mus los thiab khaws cia yooj yim. Tiv tauj peb pab neeg muag khoom tshwj xeeb rau quotes thiab tso kev txiav txim

Sib piv nrog lwm cov qib Bitumen

Thaum muab piv MC-70 Asphalt nrog rau lwm qib xws li MC-30, nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias txhua qib muaj qhov tshwj xeeb zoo thiab xav txog. Thaum MC-30 bitumen tuaj yeem ua tau zoo ntawm tus nqi, ntim khoom, thiab kev tuav pov hwm, MC-70 sawv tawm rau nws cov kev siv tshwj xeeb hauv kev tsim kho, tshwj xeeb tshaj yog cov primer thiab kev tswj plua plav. Kev xaiv ntawm cov qib no feem ntau yog nyob ntawm cov kev cai tshwj xeeb ntawm qhov project, nrog rau cov xwm txheej xws li kev nyab xeeb, av, thiab kev npaj siv ua lub luag haujlwm tseem ceeb hauv kev txiav txim siab. Los ntawm kev nkag siab txog cov yam ntxwv sib txawv ntawm txhua qib, cov kws tshaj lij kev tsim kho tuaj yeem txiav txim siab xaiv kom paub meej tias kev ua tau zoo thiab kev ua tau zoo ntawm lawv cov haujlwm.
