Ntim Cov Khoom

Bitumen 20/30 yog hais txog ib qho kev nkag mus rau qib bitumen tshwj xeeb los ntawm nws tus nqi nkag, uas nyob nruab nrab ntawm 20 txog 30 decimillimeters ntawm 25 ° C. Cov khoom ntim ntawm qib no qhia txog nws qhov sib xws, ua rau nws tsim nyog rau ntau yam kev tsim kho thiab kev saib xyuas. Feem ntau, Bitumen 20/30 muaj nyob rau hauv ntau lossis raws li cov khoom ntim hauv nruas lossis hnab.

Hais txog kev ntim khoom, bitumen cov khoom siv Feem ntau muab ob qho kev xaiv tseem ceeb:

1. Kev Thauj Khoom Loj: Txoj kev no yog qhov nrov ntawm cov neeg cog lus loj lossis cov tuam txhab tsim kho uas xav tau cov khoom loj. Bulk bitumen tuaj yeem thauj mus rau hauv cov tsheb thauj khoom thauj lossis tsheb ciav hlau, ua kom cov khoom xa tuaj tau zoo thiab txo tus nqi thauj khoom.

2. Nruas lossis Ntim: Rau cov haujlwm me me lossis cov chaw muag khoom hauv cheeb tsam, Bitumen 20/30 feem ntau tuaj hauv cov nruas steel lossis cov thawv ntim nruab nrab (IBCs). Tus qauv nruas loj yog feem ntau 200 litres, ua rau nws tswj tau me me thaum tuav cov khoom ncaj ncees.

Kev saib xyuas yuav tsum tau ua thaum tuav thiab pov tseg ntawm bitumen, vim nws yog cov khoom siv roj av uas tuaj yeem ua rau muaj kev phom sij rau ib puag ncig yog tias tsis tswj kom raug. Xyuas kom zoo sealing thiab rwb thaiv tsev thaum lub sij hawm thauj khoom yog qhov tseem ceeb los tswj cov khoom zoo thiab tiv thaiv kev sib kis.

daim ntawv sau npe

Bitumen 20/30 feem ntau yog siv hauv kev tsim kho, tshwj xeeb hauv kev tsim cov asphalt sib tov. Nws cov khoom tshwj xeeb ua rau nws haum rau:

1. Kev Tsim Kho Pavement: Bitumen 20/30 feem ntau yog siv los tsim cov pob zeb asphalt rau txoj kev, muab kev ruaj khov thiab tiv taus hnav thiab tsim kua muag los ntawm cov tsheb hnyav.

2. Kev hnav khaub ncaws saum npoo: Nws kuj yog siv rau hauv daim ntaub ntawv hnav khaub ncaws saum npoo, txhim kho kev ua haujlwm tsis zoo thiab ua kom lub neej ntev ntawm txoj kev uas twb muaj lawm.

3. Roofing: Cov qib tuaj yeem siv rau hauv kev siv dej tsis zoo, nrog rau cov ntaub ntawv vov tsev, qhov twg nws cov khoom sib khi thiab tiv taus dej ua rau nws muaj kev tiv thaiv zoo tiv thaiv ya raws.

4. Cov ntawv thov kev lag luam: Lwm cov ntawv thov suav nrog nws cov kev siv hauv kev tsim cov nplaum thiab cov sealants, qhov twg nws cov yam ntxwv zoo sib xws tau txais txiaj ntsig zoo.

Lub teb chaws ntawm Ntshuam thiab ntau lawm

Kev lag luam thoob ntiaj teb bitumen pom kev tsim khoom thiab kev lag luam tseem ceeb, cuam tshuam los ntawm cov nqi roj, kev tswj hwm txoj cai, thiab kev tsim kho vaj tse. Cov neeg tsim khoom loj ntawm Bitumen 20/30 suav nrog:

• Refining Nations: Lub teb chaws nplua nuj nyob rau hauv cov khoom siv roj av, xws li Saudi Arabia, Tebchaws Asmeskas, thiab Canada, ua tus tswj cov khoom siv bitumen vim lawv muaj peev xwm ua kom zoo dua qub. Cov teb chaws no hloov cov roj nyoos rau hauv ntau yam khoom siv roj av, suav nrog qib sib txawv ntawm bitumen.

• Kev Lag Luam Tawm Tsam: Cov teb chaws xws li Is Nrias teb thiab Tuam Tshoj kuj yog cov neeg siv khoom tseem ceeb thiab cov neeg xa khoom ntawm Bitumen 20/30. Lawv cov kev tsim kho tseem ceeb ua rau muaj kev xav tau asphalt thiab lwm yam khoom siv hauv tsev.

• Cov teb chaws Europe: Ntau lub tebchaws nyob sab Europe, suav nrog Netherlands thiab Lub Tebchaws Yelemees, yog qhov tseem ceeb rau kev tsim khoom thiab kev xa tawm ntawm qib bitumen no. Lawv cov phiaj xwm kev tsim kho tshiab tsim kom muaj kev lag luam ruaj khov rau cov ntaub ntawv zoo li no.

• Ntshuam los ntawm Ntau Qhov Chaw: Vim yog cov kev cai hauv cheeb tsam thiab cov peev txheej tsim khoom hauv zos, ntau lub teb chaws import Bitumen 20/30 los ntawm ntau qhov chaw. Kev lag luam thoob ntiaj teb no pab kom sib npaug ntawm cov khoom siv thiab kev xav tau hloov pauv hauv ntau thaj tsam.
