Muaj ntau cov ntaub ntawv uas cov kws tsim khoom thiab cov neeg ua haujlwm hauv ntau yam kev lag luam tau ntsib. Cov no suav nrog bitumen thiab tar. Sab nraud, cov ntaub ntawv zoo sib xws hauv ob qho tib si thiab hauv qee tus yam ntxwv. Qhov no yog vim li cas lawv feem ntau tsis meej pem. Tab sis qhov tseeb, nco txog qhov sib txawv yog yooj yim heev.

Dab tsi yog qhov txawv ntawm keeb kwm thiab kev sib xyaw?

Tar yog cov khoom lag luam ua kom zoo, lossis theej, qhov seem ntawm cov txheej txheem no . Cov muaj pes tsawg leeg muaj cov roj av resins, ntau cov hydrocarbons thiab ib feem me me ntawm cov hlau. Cov khoom sib piv hauv qhov ntom ntom rau dej. Cov tshuaj tau tshwm sim tsis ntev los no.

Bitumen yog cov khoom lag luam tshiab, feem ntau yog tawv . Nws yog tsim los ntawm tar. Cov tshuaj muaj pes tsawg leeg ib txwm ua raws cov pa roj carbonaceous. Txawm li cas los xij, cov khoom sib txawv yog nyob ntawm qhov keeb kwm ntawm cov tshuaj.

Bitumen feem ntau tau txais vim qhov tseeb tias cov roj tso nyiaj tsis tau khaws cia kom raug . Yog li, cov tshuaj lom neeg hloov pauv nyob rau hauv cov pa oxygen, thiab tau txais cov khoom tshiab. Ntau yam tshuaj lom neeg tuaj yeem ua rau tsim cov tshuaj. Qhov no yog qhov sib txawv tseem ceeb ntawm tar, vim tias tom kawg yog ua los ntawm kev dag. Cov khoom yog tsuas yog mined.

Qhov muaj pes tsawg leeg ntawm cov tshuaj thiab nws cov khoom nyob ncaj qha rau cov yam ntxwv ntawm thawj cov roj. Thiab cov txheej txheem ntawm kev tsim cov tshuaj kuj cuam tshuam rau. Kuj tseem muaj qhov hloov pauv ntawm bitumen . Hauv qhov no, rau kev tsim khoom, cov khoom lag luam ntawm kev ua ntawm shale, thee thiab roj tau siv.

Ntuj bitumens tau paub rau tib neeg tau ntau xyoo . Muaj keeb kwm pov thawj tias cov yas no tau siv los ntawm cov neeg Sumerians thaum ub. Tom qab ntawd cov tshuaj tau kho nrog cov ntaub pua tsev. Cov neeg Iyiv thaum ub tau siv bitumen los ua mummies. Muaj pov thawj pom tias txawm tias tib neeg hauv Neolithic siv bitumen los txuas cov taub hau rau lub hauv paus.

Cov tawv tawv tawv tawv tau khawb rau hauv qhov chaw ntuj uas muaj cov roj. Txawm li cas los xij, niaj hnub no, cov khoom tsis tshua muaj siv hauv nws daim ntawv dawb huv. Ntau yam thev naus laus zis tau siv los txhawm rau txhim kho cov khoom thiab cov yam ntxwv ntawm bitumen. Hauv qee kis, cov khoom yuav txawv qhov tseeb vim yog qhov ua haujlwm. Nov yog qhov sib txawv tseem ceeb ntawm bitumen thiab tar.

1. Tar yog qhov seem tom qab ua kom cov roj ua kom zoo, tab sis cov khoom thib ob muaj nyob hauv qhov. Txawm li cas los xij, ob qho tib si yog roj av raws.
2. Cov tawv tawv tawv muaj ntau qhov sib xyaw ua ke. Raws li qhov tshwm sim, ob lub zog thiab thaj chaw ntawm kev thov yog dav dua.
3. Qee zaum tar tau siv los ua bitumen. Nws tsis tuaj yeem ua haujlwm rov qab. Ntau yam tshuaj lom neeg tau ntxiv rau hauv tar ua rau nws nyuaj thiab ruaj khov.
4. Bitumen tau siv nyob rau ntau thaj chaw ntawm lub neej dua li tar.

Ob qho khoom siv tau ua los ntawm roj, yog li lawv zoo ib yam nkaus. Txwv tsis pub, muaj ob peb qhov sib txawv. Txawm tias thaj tsam ntawm daim ntawv thov sib txawv.

Bitumen tau paub ntau xyoo, tab sis tar tsuas yog tshwm sim thaum cov roj ua kom huv.

Cov ntawv thov

Tar feem ntau siv rau kev tsim cov hom nrov tshaj plaws ntawm bitumen. Thiab tseem yog cov khoom tsim nyog hauv kev tsim cov roj av, cov hmoov tshauv qis, cov roj rau lub cav, cov pa roj tuaj yeem sib txuas tau. Tus so ntawm qhov kev siv yog me me. Tar yog siv rau rwb thaiv tsev thaum ua haujlwm hauv tsev, txhawm rau npog txoj kev.

Bitumen tuaj yeem yog hom sib txawv thiab tsim tawm. Los ntawm kev tsim, muaj ntau qhov kev hloov pauv nrov tshaj plaws. Tus nqi ntawm ntau yam kuj tsis zoo ib yam.

Ntxiv mus, yog tias peb sib piv nrog cov ntaub ntawv zoo sib xws, tom qab ntawd tus nqi yog qhov zoo tshaj plaws, pheej yig tshaj plaws.

Lub peev txheej ntawm kev thov bitumen nyob ntawm nws hom

1. Tsev . Cov khoom tsim nyog rau kev tiv thaiv dej. Nws yog siv hauv kev tsim kho ntau yam qauv, tsev, vaj tse. Cov khoom siv tau suav tias yog qhov zoo tshaj plaws, yog qhov zoo ntawm tus nqi pheej yig.
2. Ru tsev . Bitumen ntawm hom no tau siv hauv kev tsim cov khoom vov tsev, rubemast, iav, hydroglass. Thiab tseem yog cov khoom tsim nyog hauv kev tsim cov mastic, primer, rubitex. Cov tshuaj kuj tseem siv los tsim cov ntawv bituminous thiab fiberglass.

3. Txoj kev . Txoj kev saum npoo yog kho nrog cov bitumen. Yog li cov ciav hlau tau txais ntau yam khoom muaj txiaj ntsig, lawv dhau los ua rau hnav tsis taus.

Khoom bitumen kuj tseem siv hauv qee thaj chaw ntawm kev lag luam hauv tebchaws . Yog li, nws tuaj yeem pom nyob hauv cov chaw tsim khoom, hluav taws xob engineering teb. Cov khoom siv yog siv rau tawv tawv, ntoo thiab ntawv. Cov tshuaj yog siv los tiv thaiv dej. Nws tau pom tias yog cov khoom siv raw hauv kev tsim khoom ntawm ntau cov kua roj vanish thiab xim, nrog rau hauv kev lag luam polymer.

Lwm qhov sib txawv yog dab tsi?

Tar yog tsim tshuaj lom neeg, tab sis bitumen yog ntuj kiag li. Tib lub sijhawm, tom kawg ua kom khov thiab hloov mus ua pob zeb tawv. Tab sis tar yog ib txwm khov, ntws, txawm tias qis dua. Bitumen tau siv ntau dua los ua cov khoom siv. Nyob rau tib lub sijhawm, tar hauv nws daim ntawv dawb huv feem ntau ua raws li cov khoom siv raw.
