Tshuaj Tshuaj Muaj Zog

Benzene yog qhov tseeb, hloov tsis muaj xim, tsis muaj xim, cov kua muaj xim tsis muaj ntxhiab nrog cov kua qab, tus yam ntxwv tsw. Nws yog ib qho muaj ntxhiab hydrocarbon uas boils ntawm 80.1 dc. Benzene siv raws li kev siv tshuaj tua kab mob hauv ntau qhov chaw muaj kev lag luam, xws li cov roj hmab thiab cov roj hmab tsim, thiab cov roj av, thiab cyclohexane. Nws yog qhov tseem ceeb hauv kev tsim cov tshuaj ntxuav, tshuaj tua kab, cov kuab tshuaj, thiab xim tshem tawm. Nws yog tam sim no hauv cov roj xws li roj av mus txog qib 5%.

Ntshiab, tsis muaj xim rau lub teeb daj ua kua nrog cov ntxhiab, cov hmoov av, phenolics lossis roj av-zoo li tsw. Ntawm 40 ° C, ib qho tsw tsw muaj ntxhiab ntawm 190 μg / u hauv huab cua tau txiav txim siab los ntawm cov tub ntxhais hluas li al. (1996). Ib qho ntxhiab uas muaj ntxhiab ntawm 4.68 PPMV tau txiav txim siab los ntawm Leonardos li al. (1969). Kev kuaj cov ntxhiab cuam tshuam ntawm 108 mg / mg / m3 (34 ppmv) tau tshaj tawm los ntawm Punter (1983). Qhov nruab nrab tsawg kawg yog cov ntxhiab tsw muaj ntxhiab ntawm cov dej ntawm 60 ° C thiab hauv 40 ° C yog 0.072 thiab 0.5 mg / l, feem.

Benzene tseem hloov dua siab tshiab rau cyclohexane, uas yog siv los tsim cov nylon thiab hluavtaws fibers.

Benzene tshwm sim hauv cov thee thiab thee-tar distillationproducts thiab hauv cov roj av roj av xws li cov roj av. Nws tseem muaj nyob hauv cov roj av thiab av noo ntawm cov chaw pov tseg kev lag luam, kev tsim kho cov khib nyiab, thiab kev tsim kho vaj tsheej thiab tsis kam lees ua liaj ua teb 2014 tsis kam lees ua lag luam xyoo 1989). Kev siv caj ces, toluene, xylenes, Andiath thiab cov av uas nyob ze ntau txoj av nkos qab (Asmeskas EPA 1989A, b). KRAMER (1989) tau soj ntsuam qib ntawm Exposuresto Benzene thaum tshem tawm, ntxuav, thiab kuaj ntawm cov roj av cov roj av storagetanks. Qhov nruab nrab tib neeg exposures li 0.43-3.84 ppm (hauv 1.5-6 teev) thiab lub sij hawm ntawm lub sij hawm luv luv (15-feeb) raug lawm tau yog 9.14 ppm. Benzene tseem muaj nyob hauv cov tobaccosMoke (Hoffmann li al. 1989); Yog li cov phom sij nws raug tej zaum yuav txhim kho los ntawm cov pa luam yeeb.
Benzene siv los ua cov kuab tshuaj rau waxes, resins, thiab roj; Raws li cov xim tshem tawm; raws li ib tug diluentfor lacquers; Hauv kev tsim cov dyes, tshuaj, varnishes, thiab litceum; thiab raws li cov khoom siv raw los ua ib qho khoom siv organic.

Yuav Yuav Yuav Li Cas Los Ntawm Peb

Chemwin tuaj yeem muab ntau qhov ntau ntawm hydrocarbons thiab cov kuab tshuaj lom neeg rau cov neeg siv khoom lag luam.Ua ntej ntawd, thov nyeem cov ntaub ntawv hauv qab no hais txog kev ua lag luam nrog peb:

1. Kev ruaj ntseg

Kev nyab xeeb yog peb qhov tseem ceeb tshaj plaws. Ntxiv rau muab cov neeg siv khoom nrog kev siv cov ntaub ntawv hais txog peb cov khoom lag luam, peb kuj tau cog lus tias kev muaj kev nyab xeeb ntawm cov neeg ua haujlwm thiab cov neeg ua haujlwm raug txo qis thiab ua tau tsawg kawg nkaus. Yog li ntawd, peb xav kom tus qhua tuaj noj mov kom ntseeg tau tias qhov tsim nyog tso tseg thiab kev nyab xeeb cov qauv kev nyab xeeb tau ntsib cov ntawv tshaj tawm HSSE (thov saib cov nqe lus dav dav thiab cov ntsiab lus ntawm kev muag khoom hauv qab). Peb cov kws paub HDSE tau muab cov kev taw qhia rau cov qauv no.

2. Kev Xa Tawm

Cov neeg siv khoom tuaj yeem xaj thiab xa cov khoom lag luam los ntawm Chemwin, lossis lawv tuaj yeem tau txais cov khoom los ntawm peb cov khoom lag luam tsim khoom. Cov qauv muaj kev thauj khoom muaj cov tsheb thauj neeg muaj tsheb thauj khoom, tsheb ciav hlau lossis cov neeg thauj khoom ntau (cais cov mob siv).

Nyob rau hauv cov ntaub ntawv uas cov neeg yuav tsum tau ua, peb tuaj yeem hais cov cai ntawm cov nkoj lossis cov qauv kev nyab xeeb thiab siv cov qauv kev nyab xeeb tshwj xeeb / tshuaj xyuas thiab cov tseev kom ua.

3. Yam tsawg kawg txiav txim kom muaj nuj nqis

Yog tias koj yuav khoom los ntawm peb lub vev xaib, qhov kev txiav txim yam tsawg kawg nkaus yog 30 tons.
