Qhov sib txawv ntawm cov ntxhiab tsw yog inevitably tsim thaum ibAsphalt Distributor Truckua haujlwm kev tsim kho. Qhov no yog txiav txim siab los ntawm lub cev thiab tshuaj lom neeg ntawm asphalt thiab tsis tuaj yeem zam tag nrho hauv txhua qhov xwm txheej asphalt faib; tsuas yog tsw siv thiab ntev sib txawv. Kub asphalt, hloov kho asphalt thiab emulsified asphalt feem ntau yog siv rau hauv kev tsim kho, thiab lawv qhia qhov sib txawv ntawm cov ntxhiab tsw thiab tsw ntxhiab thaum ua haujlwm.
Kub asphalt tsim cov ntxhiab tsw tshaj plaws hauv kev tsim kho. Txhawm rau ua kom tau raws li qhov xav tau ntawm kev xa mus, nws yuav tsum tau muab rhaub rau lub xeev ua kua ntawm 130℃thiab 180 degree. Nyob rau hauv qhov kub thiab txias, lub teeb-roj feem, muaj ntxhiab hydrocarbons thiab lwm yam volatile yam nyob rau hauv asphalt evaporate sai, tsim lub teeb-dub asphalt fumes nrog muaj zog pungent burnt tsw. Txhua 10℃nce nyob rau hauv qhov kub thiab txias heev accelerates volatilization thiab ho intensifies tsw. Formulated nrog SBS, roj hmab thiab lwm yam kev hloov kho, hloov kho asphalt tso tawm hnyav dua, muaj ntxhiab tsw ntau dua uas nyob ntev dua thaum kub kub volatilization.
Hauv kev sib piv, ambient-temperature emulsified asphalt yuav tsum tsis muaj cua sov siab. Nws yog atomized thiab faib tsuas yog nyob rau hauv lub siab, ua tsawg heev volatile tshuaj thiab tsis tshua muaj ntxhiab tsw. Nws NW nyuam qhuav ua kom pom tseeb cuam tshuam rau ib puag ncig ib puag ncig thiab feem ntau yog siv rau kev kho me me thiab nyias-txheej foob kev tsim kho. Sib nrug los ntawm asphalt nws tus kheej, cov khoom siv kuj tseem cuam tshuam rau qib tsw. Residual aged asphalt nyob rau hauv asphalt pipelines los yog tsis sib xws tank cua sov yuav ua rau lub zos asphalt overheating thiab carbonization, tsim muaj zog burnt tsw.
Nyob rau hauv cov nqe lus ntawm cov ntxhiab tsw thiab dissipation qauv, ntuj cua sai sai tshuab pa tawm asphalt thaum qhib-air txoj kev. Cov ntxhiab tsw tsuas yog mloog zoo nyob rau hauv 5-10-meter ua haujlwm vojvoog thiab dissipate tag nrho 10-20 feeb tom qab ua haujlwm tiav. Cov pa taws tsis tuaj yeem nthuav tawm sai sai hauv qhov av, fenced-off enclosed road sections or windless low-lying areas, ces odors tseem muaj zog thiab dissipate ntau qeeb. Lub caij no, cov hnub qis qis los nag muaj huab cua siab thiab huab cua tsis zoo, ua rau cov ntxhiab tsw nyob ntev dua li hnub tshav ntuj.
Los ntawm kev saib xyuas kev nyab xeeb-tiv thaiv, asphalt fumes muaj cov kab mob tsis haum xeeb. Ntev-ntev inhalation ua rau ua pa nyuaj. Yog li ntawd, nyob rau hauv kev tsim kho tus qauv, cov neeg ua haujlwm nyob rau ntawm qhov chaw yuav tsum hnav lub qhov ncauj qhov ntswg, hnab looj tes tiv thaiv, tiv thaiv khaub ncaws thiab lwm yam khoom siv tiv thaiv kom tsis txhob raug pa taws ntev. Cov pab pawg tsim kho yuav tsum npaj qhov cua nyob rau ntawm qhov chaw thiab tsis txhob ua haujlwm thaum lub sijhawm ua haujlwm siab tshaj nyob ze cov chaw nyob tuab kom txo tau cov ntxhiab tsw phem rau cov neeg nyob ze. Zuag qhia tag nrho, cov ntxhiab tsw ua haujlwm yog qhov tshwm sim ntawm lub cev. Kev tsim kho thiab kev tiv thaiv kom zoo tuaj yeem txo kev nyab xeeb thiab kev pheej hmoo ntawm ib puag ncig.
