Txij li thaum cov khoom siv sib xyaw asphalt siv tau yuav ntxov, nws qhov kev sib xyaw thiab ziab tuaj yeem tsuas yog ua tau raws li qhov yuav tsum tau ua rau diesel combustion. Txawm li cas los xij, raws li tus nqi ntawm diesel nce, kev lag luam ntawm kev siv cov cuab yeej ua qis dua thiab qis dua. Hauv qhov no, cov neeg siv cia siab tias nws tuaj yeem daws tau los ntawm kev hloov kho cov txheej txheem sib xyaw ntawm asphalt tov khoom. Cov kev daws teeb meem tsim nyog li cas cov kws tshaj lij muaj rau qhov no?
Kev hloov pauv ntawm kev sib xyaw ua ke ntawm asphalt tov khoom feem ntau suav nrog cov hauv qab no. Thawj yog qhov kev hloov ntawm cov khoom siv hluav taws xob sib txuas, hloov cov khoom siv hluav taws xob sib xyaw ua ke nrog cov khoom siv hnyav thiab diesel dual-purpose spray phom. Cov cuab yeej no yog luv luv thiab tsis tas yuav winding ntawm hluav taws xob cua sov xov hlau. Qhov tseem ceeb yog tias nws yuav tsis raug thaiv los ntawm cov roj hnyav hnyav, tso cai rau cov roj hnyav kom hlawv tag nrho thiab txo qis kev noj cov roj hnyav.
Qhov thib ob kauj ruam yog hloov kho lub tank diesel yav dhau los thiab nteg ib lub thermal roj coil rau hauv qab ntawm lub tank kom nws tuaj yeem siv los ua kom sov cov roj hnyav rau qhov kub thiab txias. Nyob rau tib lub sijhawm, lub txee tswj hluav taws xob cais yuav tsum tau teeb tsa rau tag nrho cov kab ke kom paub txog kev hloov pauv tsis siv neeg ntawm cov roj av thiab cov roj hnyav, thiab tiv thaiv lub kaw lus nrog lub suab nrov thiab pom lub tswb.
Lwm qhov yog kev txhim kho ntawm cov roj cua kub cua sov, vim tias qhov qub yog lub tshuab hluav taws xob hluav taws xob hluav taws xob hluav taws xob, thiab lub sijhawm no nws tau hloov nrog cov roj hluav taws xob hluav taws xob hluav taws xob, uas tuaj yeem txuag tau nyiaj ntau.
