    CHEMICAL PROPERTIES

    Benzene yog ib tug ntshiab, volatile, tsis muaj kob, heev flammable kua nrog ib tug qab ntxiag, yam ntxwv tsw.Nws yog ib qho aromatic hydrocarbon uas boils ntawm 80.1 DC.Benzene yog siv los ua cov kuab tshuaj nyob rau hauv ntau qhov chaw ntawm kev lag luam, xws li roj hmab thiab khau tsim, thiab hauv kev tsim cov khoom tseem ceeb, xws li styrene, phenol, thiab cyclohexane.Nws yog ib qho tseem ceeb hauv kev tsim cov tshuaj detergents, tshuaj tua kab, cov kuab tshuaj, thiab cov xim tshem tawm.Nws muaj nyob rau hauv cov roj xws li roj av mus txog qib 5%.

    Ntshiab, tsis muaj xim rau lub teeb daj dej nrog cov ntxhiab tsw, tsw ntxhiab, phenolics lossis roj av zoo li tsw.Ntawm 40 ° C, qhov ntsuas qhov ntsuas qhov ntsuas ntawm 190 μg / L hauv huab cua tau txiav txim siab los ntawm Young et al.(1996).Ib qho tsw qab ntawm 4.68 ppmv tau txiav txim los ntawm Leonardos li al.(1969).Kev kuaj pom tsw qhov pib qhov siab ntawm 108 mg / m3 (34 ppmv) tau tshaj tawm los ntawm Punter (1983).Qhov nruab nrab qhov nruab nrab qhov ntsuas tsis hnov ​​tsw qhov chaw nyob hauv dej ntawm 60 ° C thiab hauv huab cua ntawm 40 ° C yog 0.072 thiab 0.5 mg / L, feem.

    APPLICATION AREA

    Tshuaj
    Kev lag luam roj
    Tshuaj tua kab
    Diesel Cav Roj
    Cov tub yees
    Aerosol tshuaj tsuag

    Benzene kuj hloov mus rau cyclohexane, uas yog siv los tsim cov nylon thiab hluavtaws fibers.

    Benzene tshwm sim hauv cov thee thiab coal-tar distillationproducts thiab hauv cov khoom siv roj av xws li roj av.Nws kuj tseem pom muaj nyob hauv cov pa roj thiab cov pa phem ntawm cov chaw pov tseg rau cov khoom pov tseg, kev tsim cov khib nyiab, thiab kev tsim kho kom zoo nkauj (Oak Ridge National Laboratory 1989).Traceamounts ntawm benzene, toluene, xylenes, thiab lwm yam volatile organics tau pom nyob rau hauv cov av thiab cov dej hauv av nyob ze rau ntau yam sanitarylandfills (US EPA 1989a, b).Kramer (1989) tau soj ntsuam cov theem ntawm exposuresto benzene thaum lub sij hawm tshem tawm, ntxuav, siv, thiab kuaj cov roj av hauv av cia tank.Qhov nruab nrab ntawm tib neeg kis tau yog 0.43–3.84 ppm (hauv 1.5–6 teev) thiab qhov siab tshaj plaws luv luv (15–feeb) raug yog 9.14 ppm.Benzene kuj tshwm sim hauv kev haus luam yeeb (Hoffmann li al. 1989);yog li qhov kev pheej hmoo ntawm nws qhov kis tau tuaj yeem txhim kho los ntawm kev nqus cov pa luam yeeb.
    Benzene yog siv los ua cov kuab tshuaj rau waxes, resins, thiab roj;raws li cov xim tshem tawm;raws li ib tug diluent rau lacquers;nyob rau hauv kev tsim cov dyes, kws tshuaj, varnishes, thiab linoleum; thiab raws li ib tug raw khoom los tsim ib tug xov tooj ntawm cov organic tebchaw.

    YUAV UA LI CAS LOS NTAWM US

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

    1. Kev ruaj ntseg

    Kev nyab xeeb yog peb qhov tseem ceeb tshaj plaws.Ntxiv nrog rau kev muab cov neeg siv khoom paub txog kev nyab xeeb thiab ib puag ncig tus phooj ywg siv ntawm peb cov khoom, peb kuj tau cog lus los xyuas kom meej tias qhov kev pheej hmoo ntawm kev nyab xeeb ntawm cov neeg ua haujlwm thiab cov neeg ua haujlwm raug txo qis rau qhov tsim nyog thiab ua tau tsawg kawg nkaus.Yog li ntawd, peb xav kom tus neeg siv khoom kom ntseeg tau tias qhov tsim nyog tshem tawm thiab khaws cov qauv kev nyab xeeb tau ua tiav ua ntej peb xa khoom (thov xa mus rau HSSE appendix nyob rau hauv cov nqe lus dav dav thiab kev muag khoom hauv qab no).Peb cov kws tshaj lij HSSE tuaj yeem muab kev taw qhia txog cov qauv no.

    2. Txoj kev xa khoom

    Cov neeg siv khoom tuaj yeem xaj thiab xa khoom los ntawm chemwin, lossis lawv tuaj yeem tau txais cov khoom los ntawm peb cov chaw tsim khoom.Cov hom kev thauj mus los muaj xws li tsheb thauj mus los, tsheb ciav hlau lossis kev thauj mus los ntau yam (xws li kev sib cais).

    Nyob rau hauv cov ntaub ntawv ntawm cov neeg yuav tsum tau, peb muaj peev xwm qhia kom meej cov kev cai ntawm barges los yog tankers thiab siv tshwj xeeb kev nyab xeeb / tshuaj xyuas cov qauv thiab cov kev cai.

    3. Yam tsawg kawg nkaus 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.

    5. Cov ntaub ntawv xa tuaj

    Cov ntaub ntawv hauv qab no tau muab nrog rau txhua qhov kev xa khoom:

    · Bill of Lading, CMR Waybill lossis lwm yam ntaub ntawv thauj mus los

    · Certificate of Analysis los yog Conformity (yog xav tau)

    · Cov ntaub ntawv hais txog HSSE raws li txoj cai

    · Cov ntaub ntawv kev lis kev cai raws li txoj cai (yog tias xav tau)
