Kev siv cov oxidized bitumen

Siv rau kev tiv thaiv hauv av pob zeb, txuas hniav, culverts, tuav phab ntsa, tso tsheb hlau luam ib puag ncig, dams, conduits thiab decks.
Qib ntawm cov tawv asphalt tuaj yeem siv rau hauv kev tsim cov dej pov thawj.
Raws li MOP lub tsho tiv no rau damp proofing.
Daim ntawv cog lus zoo heev thiab nplaum.
Raw khoom ntawm mastic, primer thiab enamel.
Oxidized asphalt, hom Bitumen R115/15 Nws muaj kev tiv thaiv zoo rau qhov chaw ntsug thiab kab nqes hauv qab ntawm lub hnub ncaj qha hauv qhov kub thiab txias tshaj 50C.
Tshuab asphalt yog raws li raw khoom los tsim cov khoom pov thawj dej.

Cua tshuab asphalt

Bl bitumen yog ib yam khoom tshwj xeeb amorphous uas feem ntau yog ua kua thaum tawm los ntawm cov nroj tsuag oxidation ntawm qhov kub ntawm 240 ° txog 300 ° C., thiab dhau los ua khoom lossis pasty ntawm ambient kub. Thaum nws yog kub, nws yog khov, whereas thaum nyob rau hauv pasty los yog khoom lub xeev nws muaj ib tug ncaj ncees degree ntawm elasticity. Ob qho tib si hauv cov kua thiab cov yas los yog cov khoom siv oxidized bitumen yog cov khoom siv insulating zoo nrog cov khoom zoo adhesion nrog rau yuav luag txhua yam khoom siv.

Oxidized bitumen yog zoo li tawg muab tub lim ntawm asphalt

Oxidized bitumen siv raws li tawg sealer nyob ntawm txoj kev thiab tus qauv kuj yog nyob ntawm kev nyab xeeb thiab qhov tsawg kawg nkaus thiab siab tshaj plaws ntawm nruab hnub thiab hmo ntuj.Oxidized bitumen muaj cov viscosity siab heev thiab tom qab kev npaj ntawm qhov tawg thiab ntxuav thaj chaw tawg siv ncaj qha oxidized asphalt thiab sai sai yuav tau qhuav thiab lo rau asphalt. Oxidised asphalt ua cov cuab yeej rubberise thiab npaj qee qhov elasticity rau txoj kev.
