[1]. Eva hloov kho Bitumen Eva muaj kev sib raug zoo nrog bitumen thiab tuaj yeem yaj thiab dispersed nyob rau hauv kub bitumen tsis siv nws yooj yim siv.
Nyob rau hauv xyoo tsis ntev los no, bitumen txoj hauj lwm hauv Africa tau siv ntau zaus, yog li cov neeg ua haujlwm hauv tsev tau nco qab kom them sai sai.
[2]. Siab viscosity, siab elasticity thiab siab todomness hloov batumen. Lub bitumen viscosity thiab kev ntsuam xyuas todualness yog qhov tsim nyog dua rau sbr hloov kho me ntsis, tab sis thaum siv rau kev sim siab heev, ua qhov kev sim ua tsis tau. Hauv kev pom ntawm qhov no, nws raug nquahu kom siv cov tshuab ntsuas tshuab thoob ntiaj teb los ua qhov kev sib tw zoo nkauj, thiab siv txoj kev sib koom tes kom yooj yim laij cov ntawv xeem. 3. Cov ntaub ntawv roj hmab ntau dua hloov kho nrog cov pa roj carbon neuurbation thiab kev txuag hluav taws xob, txo qhov kev txo hluav taws xob yog qhov tseem ceeb. Cov log tsheb tau ntsib qhov teeb meem ntawm "huab hwm coj ntau lawm thiab huab hwm coj loj loj" txij li thaum nws muaj kev tsim khoom. Cov log tsheb yuav tsum ncaj qha lossis tsis ncaj kev noj ntawm cov khoom siv hauv ntuj thiab lub zog los ntawm kev tsim khoom rau pov tseg, ua rau muaj ntau cov pa roj carbon dioxide loj.
Lub ntsiab tiv thaiv ntawm cov log tsheb yog carbon, thiab txawm pov tseg cov log tsheb muaj ntau dua 80% cov ntsiab lus carbon. Cov log tsheb khib nyiab tuaj yeem rov ua tau cov khoom siv thiab lub zog loj, kho cov pa roj carbon rau hauv cov khoom, thiab ua tiav lub hom phiaj txuag thiab emission txo. Cov log tsheb khib nyiab yog polymer elastic cov ntaub ntawv uas nyuaj heev rau kev ua txhaum. Lawv muaj cov elasticity thiab tawv thiab yuav luag tsis muaj kev hloov pauv ntawm lub cev lossis tshuaj lom tshwm sim hauv qhov ntsuas kub ntawm -50c mus rau 150c. Yog li ntawd, yog tias lawv raug tso cai rau degree ib txwm nyob rau hauv av, lawv yuav tsis cuam tshuam rau qhov ntev ntawm kev loj hlob ntawm cov nroj tsuag, cov txheej txheem tuaj yeem siv sijhawm li 500 xyoo. Coob tus ntawm cov log tsheb loj yog piled up arbitrarily thiab nyob ib qho ntau ntawm cov av, tiv thaiv kev siv cov av muaj txiaj ntsig zoo. Ntxiv mus, kev siv dej ntev ntxiv hauv cov log tsheb yuav yug menyuam yoov thiab kis cov kab mob, ua rau cov neeg muaj kev phom sij rau tib neeg txoj kev noj qab haus huv.
Tom qab cov tshuab sib tsoo cov log tsheb rau cov roj hmab hmoov, kev siv roj hmab zoo heev, kev txhim kho txoj hauv kev zoo heev, thiab txo txoj kev tsheb. Siv peev siv.

[3]. Vim li cas nws "high-confess cov roj hmab sib txuas hloov kho bitumen"?
Tsawg tsawg kub nthuav tawm
Cov roj hmab hauv cov khib nyiab log roj hmab hmoov muaj cov roj hmab ntau dua, thiab ruaj khov rau cov khoom siv roj hmab tsawg, uas txhim kho qhov kub thiab txias ruaj khov ntawm babumen thiab sib tov. Cov tshuaj tiv thaiv kab mob nplua thiab nrov nrov-txo cov pob txha sib tov sib xyaw muaj qhov tob ntawm txoj kev ua tau zoo ntawm txoj kev saum npoo.
Cov roj hmab bitumen tuaj yeem txo lub suab nrov tsav tsheb los ntawm 3 txog 8 decibels thiab muaj kev ruaj khov zoo. Khib log roj hmab hmoov muaj cov tshuaj tiv thaiv kab mob antioxidants, cua sov stabilizers, lub teeb thaiv tiv thaiv cov neeg sawv cev thiab carbon dub. Ntxiv bitumen tuaj yeem qeeb me ntsis kev laus ntawm bitumen thiab txhim kho qhov zoo ntawm kev sib xyaw. Lub durability thiab kev pab cuam sib raug zoo ntawm 10,000 tons ntawm roj hmab bitumen yuav tsum tau noj ntawm tsawg kawg yog 50,000 tus tons 2,000 rau 5,000 tons 2,000 rau 5,000 tons ntawm bitumen. Cov khoom pov tseg kev khib nyiab yog qhov siab, lub zog txuag thiab kev nplij siab ib puag ncig yog qhov sib txawv, thiab lub Elastomer txoj kev sib tw yog qhov txawv ntawm lwm txoj kev. Piv nrog rau kev ruaj khov thiab xis nyob, nws yog qhov zoo dua.
Cov pa roj carbon dub tuaj yeem khaws cov xim dub ntawm txoj kev saum npoo ntev ntev, muaj qhov sib piv siab nrog cov cim thiab kev pom zoo ua kom pom tseeb. 5. Nws undergoes hloov hauv tshav kub, siab, oxidation, thiab melting. Bitumen-zoo li cov tshuaj zoo li tau tsim nyob hauv qab kev ua ke ntawm kev ua haujlwm thiab cov kab mob. Nws yog hom bitumen. Lwm yam bitumens suav nrog Lake Bitumen, submarine bitumen, thiab lwm yam.

Tshuaj lom neeg tshuaj lom neeg: qhov hnyav molecular ntawm Asphaltenes hauv pob zeb bitumen ranges los ntawm ntau txhiab mus rau kaum txhiab. Cov tshuaj lom neeg muaj kuab lom yog 81.7% carbon, 7.5% hydrogen, 2.3% paken, 4.4% leej faj, 1.1% txhuas, thiab 0.18% silicon. thiab lwm yam meters 0.87%. Ntawm lawv, cov ntsiab lus ntawm Carbon, hydrogen, oxygen, nitrogen, thiab leej faj yog qhov siab. Yuav luag txhua macromolecule ntawm aspaltetrale muaj cov pab pawg ua haujlwm ntawm cov ntsiab lus saum toj no, uas ua rau nws ua kom muaj zog tshaj tawm ntawm lub pob zeb. Tiam thiab keeb kwm: pob zeb bitumen yog tsim nyob rau hauv cov nrib pleb ntawm cov pob zeb. Qhov dav ntawm cov kab nrib pleb yog nqaim heev, tsuas yog kaum tawm ntawm centimeters mus rau ntau metres, thiab qhov tob tuaj yeem ncav cuag ntau dua li ntau pua ntawm meters.

2. North American pob zeb Bitumen: Uintaite (Asmeskas Lag Luam npe Gilsonite) Basld American Bas nyob rau sab hnub tuaj ntawm Yudas, Northern Teb Chaws Asmeskas.
3. Iranian pob zeb bitumen: Qingdao muaj cov lus nug ntev.
[4]. Sichuan Qingchuan Pob Zeb Bitumen: Sichuan County, Sichuan Xeev nyob rau hauv ntau dua 1.4 lab tons thiab cov kev khaws cia ntau dua 30 lab tons. Belongs rau shandong nthuav qhia.5. Lub pob zeb backumen mine nrhiav tau los ntawm 137th regented ntawm 7 corrional ntau lawm ntawm lub voj voog 7 Kev siv thiab Genre:
1. Ncaj nraim muab tso rau hauv lub tog raj kheej sib xyaw ntawm bitumen sib xyaw chaw nres tsheb.
2. High Modulus Tus Qauv Tus Thawj Coj, thawj cov hmoov nplej, thiab tom qab ntawd ntxiv cov matrix bitumen yog hloov kho.
3. Roj hmab hmoov compounding
4. Cais roj xuab zeb thiab sib sau ua ke cov ntsiab lus asphalesente. 5. Txuas nrog cov chaw nres tsheb sib xyaw kom ntxiv cov ntawv thov tshiab online:
1. Siv rau kev yoog raws theem;
2. Siv los ncaj qha paving ntawm txoj kev nyob deb nroog;
3. Sib tov nrog cov khoom siv rov ua dua tshiab (rap) rau thermal ua haujlwm;
4. Siv bitumen activator mus rau compound kua babumen thiab txias sib tov nws rau saum npoo.
5. Lub Siab Modulus asphalt
6. Pov tseg asphalt qhob
