Lub ntsiab lus ntawm Bitumen AC 20

Nws tseem hu ua Asphalt Cement 20, yog ib hom bituminous binder siv dav hauv kev tsim kho thiab Txoj kev lees paub tej yaam num. Muab tau los ntawm roj av distillation, nws yog ib qho viscous, dub, ib nrab khoom paub txog nws cov nplaum thiab waterproofing khoom. Nws plays lub luag haujlwm tseem ceeb hauv kev tsim kom ruaj khov asphaltt sib tov, coatings nto, thiab pavement sealants, kom ntseeg tau lub neej ntev thiab kev ncaj ncees ntawm txoj kev thiab lwm yam infrastructure tej yaam num.

Cov khoom ntawm Viscosity Qib 20

Cov khoom tshwj xeeb ua rau nws yog qhov kev xaiv zoo tshaj plaws rau kev thov kev tsim kho:

adhesion: Exhibits zoo heev bonding zog nrog ntau yam aggregates thiab substrates, kom ntseeg tau muaj zog thiab ruaj khov txoj kev chaw.

yooj Yim: Withstands thermal expansion thiab contraction, ua rau nws haum rau ntau haiv neeg kev nyab xeeb thiab ib puag ncig tej yam kev mob.

Dej Kuj Muab kev tiv thaiv zoo tshaj plaws tiv thaiv kev puas tsuaj rau cov dej noo, ncua lub neej ntawm txoj kev thiab pavements.

Kub-kub Stability Khaws cov qauv kev ncaj ncees txawm tias nyob rau hauv huab cua kub, txo qhov kev pheej hmoo ntawm rutting thiab deformation.

Daim ntawv thov ntawm Viscosity Qib 20

Nws yog dav siv nyob rau hauv kev tsim kho kev lag luam rau:

Asphalt Mixes: Cov khoom tseem ceeb hauv kev tsim cov khoom zoo asphalt sib tov rau txoj kev.

Nto Coatings: Siv nyob rau hauv cov txheej txheej saum npoo rau cov chaw nres tsheb, kev tsav tsheb, thiab lwm qhov chaw paving.

Pavement Sealing: Siv rau pavement sealing los tiv thaiv dej infiltration thiab tiv thaiv cov kab nrib pleb thiab poholes.

Ntim, tuav, thiab cia

Cov txheej txheem tsim nyog rau ntim, tuav, thiab khaws cia muaj xws li:

Ntim: Feem ntau ntim rau hauv cov thoob los yog tso tsheb hlau luam kom muaj kev ncaj ncees ntawm cov khoom.

Kev tuav: Ua raws li cov txheej txheem kev nyab xeeb thiab siv cov cuab yeej tsim nyog kom tsis txhob muaj xwm txheej thiab nchuav.

cia: Khaws rau hauv qhov chaw txias, qhuav kom deb ntawm tshav ntuj ncaj qha thiab qhov chaw tshav kub kom khaws cov khoom thiab ua kom lub neej ntev.

Tus nqi ntawm Bitumen AC 20

Tus nqi sib txawv raws li qhov zoo, qhov ntau, kev xav tau ntawm kev lag luam, thiab tus nqi muag khoom. Ntawm Basekim, peb muab cov nqi sib tw rau hwm Bitumen AC 20, kom ntseeg tau tias tus nqi zoo yam tsis muaj kev cuam tshuam zoo.
