TusKaw nyem taw qhia ForalyerNyob rau hauv Wuhan UHV tuaj yeem pab cov neeg ua haujlwm ua haujlwm ntau lub zog ua ntau yam kev ntsuas hluav taws xob ntau dua.
Nov yog ib lo lus nug tseem ceeb thiab tseem ceeb heev. Kev txiav txim siab rau ntsais nyem ntawm cov khoom siv roj av yog qhov ntsuas kev tseem ceeb rau kev ntsuas nws qhov kev nyab xeeb thiab kev ua tau zoo.
Tsuas yog muab tso, lub hom phiaj tseem ceeb ntawm kev txiav txim plaub lub ntsej muag ntawm cov khoom siv hluav taws xob yog los ntsuas nws cov hluav taws kub, yog li ua kom muaj kev nyab xeeb, cia, thiab siv.
Tshwj xeeb, nws tuaj yeem tawg rau hauv cov laj thawj hauv qab no:
1. Lub ntsiab lus tseem ceeb ntawm kev nyab xeeb (thawj qhov laj thawj)
Kev faib tawm ntawm cov hluav taws kub nyhiab: lub flash point yog qhov tseem ceeb tshaj plaws rau kev txiav txim rau cov khoom phom tua hluav taws ntawm cov khoom siv roj av. Ib qho qis dua flash point qhia tias cov khoom tuaj yeem tso cov pa hluav taws uas muaj huab cua kom qhuav lossis tseem tawg thaum ntsib cov nplaim taws qhib lossis ua txhaum.
For example: Gasoline has a very low flash point (approx. -43°C), making it an extremely flammable liquid that requires strict fire and explosion prevention measures. Lubricating oil, on the other hand, has a very high flash point (usually >200 degree) thiab muaj kev nyab xeeb heev ntawm chav sov.
Tsim cov txheej txheem kev nyab xeeb: raws li Flash cov ntaub ntawv taw qhia, ua kom muaj kev nyab xeeb txoj kev ua haujlwm muaj kev nyab xeeb rau kev tsim nyog, suav nrog:
Kev Cia Cov Neeg Tiv Thaiv: Kev txiav txim siab hom tank tank (piv txwv li, chav tsev ntab), cov tshuab ua kom sov yog xav tau.
Yuav tsum thauj mus los: Txiav hom kev thauj khoom (piv txwv li, nkoj, tsheb thauj khoom, kom ua tiav cov kev cai los thauj cov kev cai rau kev thauj cov kua (piv txwv li, imo's IMDG code).
Kev ua haujlwm ib puag ncig: nyob rau hauv ib cheeb tsam uas muaj peev xwm ua kom zoo nkauj thiab siv cov chaw nres tsheb tsim nyog, tshuaj tiv thaiv kev puas tsuaj, anti} zoo li qub, thiab ntsuas hluav taws xob zoo li qub.
2. Ntsuas cov tsis sib xws thiab cov ntsiab lus sib xyaw ua ke
Distillation muaj pes tsawg leeg: Lub nyem taw tes yog ze ze rau cov khoom siv distillation ntawm cov khoom. Cov khoom lag luam uas muaj lub teeb qis qis feem ntau muaj cov feem ntau lub teeb (tsawg molecular hnyav (tsawg boiling point) thiab yog ntau qhov txawv.
Kev tswj kom zoo: thaum lub sijhawm tsim khoom, lub flash taw tes yog qhov tseem ceeb tswj hwm qhov ntsuas. Piv txwv li:
Roj Roj: Yog hais tias lub flash taw tes yog tsawg heev, nws qhia tau cov lu hluav taws xob (piv txwv li, uas tsis yog muaj txiaj ntsig rau cov kev ua haujlwm cav.
Lubricating roj: Lub ntsej muag qis hauv cov roj tshiab yuav qhia tsis txaus ntawm cov roj hauv qab, muaj ntau lub teeb sib xyaw. Ib qho kev txo qis tseem ceeb ntawm kev siv roj siv lubricating yog qhov kev ceeb toom ceeb toom los ntawm roj (diesel), feem yuav tsum tau hloov pauv kom tiv thaiv kom tsis txhob muaj kev phom sij ntxiv thiab tua hluav taws.
3. Kev txheeb xyuas cov kev paug thiab tsis zoo
Kev kuaj mob: Raws li tau hais, kev soj ntsuam cov flash taw ntawm cov roj lubricating roj yog qhov tseem ceeb rau kev tshuaj xyuas cov xwm txheej. Ib pliag poob rau hauv Flash taw tes yuav luag yeej qhia tau roj ua paug tsis huv.
Kev txiav txim siab tsis zoo: Rau cov roj av insulating lossis roj hloov pauv, qhov tsis txaus ntseeg hauv cov roj tau tawg los yog oxidized vim tias overheating, ua kom muaj zog heev, ua rau cov khoom siv hnyav.
