Bitumen Melting cov cuab yeej yog cov cuab yeej siv tshuab tshwj xeeb siv los ua kom sov thiab melt bitumen. Peb lub tuam txhab cov khoom lag luam tau pom dav dav thiab thov hauv kev ua lag luam.
Peb cov txheej txheem ntau lawm yog: thauj cov roj kub thiab roj av nrawm nrawm nrawm nrawm nrawm lossis ua tiav cov khoom siv uas yuav tsum tau ua tiav lossis cov ntaub ntawv tiav. Qhov kom zoo dua yog tias nws tuaj yeem ua qhov zoo tshaj plaws siv cov ntaub ntawv raw thiab txo kev siv zog siv hluav taws xob; Nyob rau tib lub sijhawm, nws kuj tseem tuaj yeem kho cov khoom ntawm cov kev sib txawv sib xws raws li kev xav tau sib txawv raws li cov neeg siv khoom sib txawv. Ib qho ntxiv, peb muab kev pabcuam tom qab muag thiab kev txhawb nqa los tiv thaiv cov kev nyiam thiab kev nyab xeeb ntawm peb cov neeg siv khoom.
Peb cov khoom siv melting melting muaj cov txiaj ntsig hauv qab no:

1 .: Siv cov thev naus laus zis cua txias heev, nws tuaj yeem yaj bitumen sai sai thiab zoo thaum txuag lub zog.
2
3. Yooj yim rau kev khiav lag luam: Cov khoom siv muaj cov kev tswj hwm zoo, uas yog qhov yooj yim ua haujlwm, tswj thiab tswj hwm.
4. Kev tiv thaiv ib puag ncig thiab kev nyab xeeb: cov cuab yeej siv tau ua tiav cov roj av tiv thaiv kev khib nyiab, dej khib nyiab thiab cov suab nrov thiab ua kom muaj kev nyab xeeb ntawm cov neeg ua haujlwm.
5. Kev thov ntau: cov khoom siv tau haum rau ntau hom bitumen, suav nrog kub sib tov asphalt, txias sib xyaw bitumen, thiab lwm yam.
