N-hexane
n-Hexane yog ib qho kev lag luam organic hnyav uas tau siv dav rau nws cov txiaj ntsig tab sis muaj kev pheej hmoo rau kev noj qab haus huv tseem ceeb. Nws cov yam ntxwv txhais tau tias yog kev sib koom ua ke ntawm "kev siv hluav taws xob siab" thiab "siab toxicity" - nws yog ob qho tib si kev tshem tawm thiab tu tus neeg saib xyuas thiab pom zoo neurotoxin.
🔬 yog dab tsi?
n-Hexane yog ib qho ncaj- saws saturated hydrocarbon nrog cov tshuaj formula C₆H₁₄, muab los ntawm roj av refining. Nyob rau hauv chav tsev kub, nws yog ib tug tsis muaj kob, volatile kua heev nrog ib tug tshwj xeeb roj av - zoo li tsw.

🏭 Main Applications
Roj Extraction- Nws txoj kev siv loj tshaj plaws yog hauv kev rho tawm cov roj noj tau los ntawm cov qoob loo xws li taum pauv thiab txiv laum huab xeeb.
Industrial Solvent- Siv los ua cov kuab tshuaj hauv cov roj hmab, cov xim pleev xim, cov ntawv pleev xim, cov nplaum, thiab ua cov tshuaj ntxuav tes rau cov khoom siv hluav taws xob thiab cov cuab yeej precision (feem ntau hu ua "cov roj dawb" lossis "dawb plig" hauv qee qhov ntsiab lus).
⚠️ Core Risk: Neurotoxicity
Qhov teeb meem kev noj qab haus huv tseem ceeb ntawm n-hexane yogkev puas tsuaj rau lub paj hlwb peripheral. Qhov kev puas tsuaj no tuaj yeem tshwm sim tsis txaus ntseeg nyob rau hauv ntev -lub sijhawm, qis- theem raug thiab yuav tsis tshwm sim kom txog thaum muaj kev puas tsuaj loj.
Cov tsos mob thaum ntxov: loog thiab paresthesia (ib qho "pob looj tes-thiab- khoom") ntawm txhais tes thiab taw, tsis muaj zog, tshwj xeeb tshaj yog pom thaum taug kev lossis nce ntaiv.
Qhov tshwm sim hnyav: Ntev ntev tuaj yeem ua rau cov leeg nqaij atrophy nyob rau hauv lub distal extremities thiab txawm tuag tes tuag taw. Txawm tias tom qab kev kis tus kab mob no lawm, tus mob yuav mus ntxiv mus rau qee lub sijhawm, thiab kev rov qab los qeeb (yuav siv sijhawm ntau dua ib xyoos).
Cov pov thawj scientific: Kev tshawb fawb ntawm cov neeg ua haujlwm tau pom tias txawm tias qhov chaw ua haujlwm n- hexane concentrations tseem qis dua lub teb chaws ua haujlwm raug txwv (100 mg / m³), cov neeg ua haujlwm raug pom muaj ntau dua cov ntshav ntawm cov neuron tshwj xeeb enolase (NSE) thiab neurofilament protein (NF) piv rau pawg tswj hwm, thiab cov qib no tau nce ntau xyoo ntawm kev pabcuam. Qhov no qhia tau hais tias kev puas hlwb puas yuav tshwm sim txawm tias ua ntej tus qauv txwv tsis pub dhau.
🛡️ Yuav Tiv Thaiv Koj Tus Kheej Li Cas?
Muab nws cov flammability siab thiab neurotoxicity, nruj ua raws li cov txheej txheem kev nyab xeeb yog qhov tseem ceeb thaum tuav n-hexane.
Engineering Controls: Kev khiav hauj lwm yuav tsum tau ua nyob rau hauv fume hoods los yog zoo-ventilated qhov chaw, nrog rau tag nrho cov ignition qhov chaw. Cov khoom siv hluav taws xob tawg yuav tsum tau siv.
Cov Khoom Siv Tiv Thaiv Tus Kheej (PPE): Hnav kom haumchemical-resistant hnab looj tes(piv txwv li, fluororubber, nitrile roj hmab) thiablooj tsom iav dubtiv thaiv daim tawv nqaij thiab qhov muag. Nyob rau hauv ib puag ncig high-concentration los yog tsis zoo ventilated qhov chaw,Lub tshuab ua pa nrog cov pa roj carbon monoxideyuav tsum tau.
Kev Ua Haujlwm: Noj, haus, lossis haus luam yeeb hauv chaw ua haujlwm raug txwv nruj heev. n-Hexane yuav tsum tsis txhob siv rau cov hom phiaj tsis tsim khoom xws li ntxuav tes lossis ntxuav khaub ncaws.
Kev Txwv Kev Ua Haujlwm (Tuam Tshoj GBZ 2.1-2019):
PC-TWS(Kev tso cai Concentration-Time Weighted Average): 100 mg/m³
PC-STEL(Kev Tso Cai Tso Cai-Short Term Exposure Limit): 180 mg/m³
Yog tias koj ua haujlwm nrog n-hexane, ua tib zoo saib xyuas cov tsos mob ntawm lub paj hlwb thaum ntxov thiab ua raws li tag nrho cov txheej txheem kev nyab xeeb. Yog tias koj xav tias kis tau los yog muaj kev txhawj xeeb, nrog rau tus kws kho mob ua haujlwm.
