Taw qhia rau Bitumen Roj

Bitumen roj tej zaum yuav tsis yog cov khoom flashiest nyob rau hauv lub ntiaj teb no theem, tab sis nws plays ib tug tseem ceeb luag hauj lwm nyob rau hauv infrastructure, los ntawm txoj kev du mus rau waterproof rooftops. Txawm hais tias koj nyob hauv kev tsim kho, kev xa khoom, lossis cov khoom lag luam, nkag siab txog cov txiv ntoo thiab cov bolts ntawm cov roj bitumen tuaj yeem txuag koj nyiaj, txo qhov project downtime, thiab pab koj xaiv cov khoom tsim nyog.

Bitumen Roj yog dab tsi?

Keeb kwm thiab txhais

Bitumen yog ib qho tsaus nti, nplaum nplaum tau los ntawm cov roj crude. Nws yog cov binder uas tuav asphalt ua ke thiab yog pom los yog tsim los ntawm kev ua kom zoo. Bitumen roj, tshwj xeeb, yog hais txog cov kua los yog semi-kua daim ntawv siv feem ntau hauv kev tsim kho.

Cov yam ntxwv ntawm lub cev thiab tshuaj lom neeg

Bitumen yog waterproof, tshuaj ruaj khov, nplaum nplaum, thiab resistant rau degradation-ua rau nws zoo tagnrho rau kev siv mus ntev. Nws muaj viscosity siab thiab softening point thiab yuav tsum tau tuav thiab khaws cia nyob rau hauv qhov tseeb kub tswj.

Yuav ua li cas Bitumen roj ua

Ntuj tshwm sim vs. Refined Bitumen

Thaum ib txwm tshwm sim bitumen tshwm sim (piv txwv li, hauv cov av xuab zeb), feem ntau ntawm cov khoom lag luam bitumen yog los ntawm cov seem ntawm cov roj crude distillation.

Cov txheej txheem Distillation hauv Refineries

Nyob rau hauv refineries, cov roj crude undergoes fractional distillation. Cov khoom sib zog xws li roj av thiab diesel raug cais ua ntej. Dab tsi tseem nyob hauv qab yog lub tshuab nqus tsev vacuum - qhov no ua bitumen.

Oxidation thiab Cua-Blown Bitumen

Ntxiv cov txheej txheem zoo li oxidation pab tsim cov qib sib txawv ntawm oxidized bitumen xws li 115/15 nrog cov khoom xav tau. Cua-blown bitumen feem ntau yog siv nyob rau hauv ru tsev thiab kev lag luam chaw vim nws txhim khu kev laus tiv thaiv.

Qib ntawm Bitumen Roj

Nkag qib Bitumen

Txhais los ntawm nws tus nqi nkag ntawm 25 ° C (piv txwv li, 60/70, 80/100), qhov no yog cov feem ntau siv bitumen hauv kev tsim kho.

Viscosity Qib Bitumen

Siv nyob rau hauv cov teb chaws xws li Is Nrias teb, VG qib (VG10, Bitumen VG30, VG40) kom zoo dua qhov kub thiab txias dua li qib nkag.

Kev Ua Haujlwm Qib Bitumen

PG bitumen yog siv nyob rau hauv Teb Chaws Asmeskas thiab Canada. Nws raug kuaj raws li kev nyab xeeb, xws li PG 76-22 rau cov cheeb tsam kub.

Hloov Bitumen (PMB, CRMB, SBS)

Ntxiv cov polymers txhim kho elasticity thiab qaug zog tiv thaiv. Siv nyob rau hauv cov chaw tsheb loj thiab huab cua huab cua.
