hardest qib ntawm bitumen
Dab tsi yog qib nyuaj ntawm bitumen?
Qib hardest ntawm bitumen nws tsis txhais hais tias vim koj tuaj yeem ua rau nws nyuaj thiab nyuaj los ua coke thiab nws yog hom bitumen ib yam nkaus. Feem ntau peb cov neeg siv khoom 115/15 uas yog 115C li softening point thiab 15 li nkag thiab nws yog yooj yim tawg.
muaj cov qib tshwj xeeb nyuaj nrog rau 150C li mos thiab 5 raws li kev nkag mus tab sis nws nyuaj heev rau cov khoom thiab cov neeg siv khoom xav tau ntau lub zog kom yaj nws li ob peb tus neeg yuav khoom txaus siab rau qib no thiab kim heev piv 115/15.
Cov khoom ntawm qib nyuaj ntawm bitumen
- Nws yog breakable
- Tsis yooj yim rau deform nyob rau hauv chav tsev kub
- Tsis yooj yim rau yaj tsawg tshaj li softening point
- Nquag ntim rau hauv 25kg hnab kom muaj peev xwm kom yaj nws yooj yim dua
- Tom qab siv rau saum npoo tam sim ntawd yuav tau khov.
Kev siv cov tawv bitumen
- nws yog siv nyob rau hauv cov yeeb nkab txheej
