    ZINTHU ZA MANKHWALA

    Benzene ndi madzi omveka bwino, osasunthika, opanda mtundu, omwe amatha kuyaka kwambiri ndi fungo labwino, lodziwika bwino.Ndi hydrocarbon yonunkhira yomwe imawira pa 80.1 DC.Benzene amagwiritsidwa ntchito ngati zosungunulira m'madera ambiri a mafakitale, monga kupanga mphira ndi nsapato, komanso kupanga zinthu zina zofunika, monga styrene, phenol, ndi cyclohexane.Ndikofunikira popanga zotsukira, mankhwala ophera tizilombo, zosungunulira, ndi zochotsera utoto.Imapezeka mumafuta monga petulo mpaka 5%.

    Madzi amadzi owoneka bwino, opanda utoto mpaka achikasu okhala ndi fungo lonunkhira bwino, laphimbi, phenolic kapena fungo longa mafuta.Pa 40 ° C, fungo la 190 μg / L mumlengalenga linatsimikiziridwa ndi Young et al.(1996).Kununkhira kwa 4.68 ppmv kunatsimikiziridwa ndi Leonardos et al.(1969).Kuzindikira kwa fungo la 108 mg/m3 (34 ppmv) kunanenedwa ndi Punter (1983).Wapakati pang'ono detectable fungo pakhomo ndende m'madzi pa 60 °C ndi mu mpweya 40 °C anali 0.072 ndi 0.5 mg/L, motero.

    APPLICATION AREA

    Mafuta amafuta
    Mankhwala ophera tizilombo
    Mafuta a Dizilo
    Refrigerant
    Aerosol Spray

    Benzene imasinthidwanso kukhala cyclohexane, yomwe imagwiritsidwa ntchito popanga nayiloni ndi ulusi wopangira.

    Benzene imapezeka muzinthu za malasha ndi malasha-tar distillation komanso mumafuta amafuta monga mafuta.Imapezekanso m'mipweya ndi zotayira zotayira m'mafakitale, zinyalala zomanga, ndi zinyalala zakumalo (Oak Ridge National Laboratory 1989).Kuchulukira kwa benzene, toluene, xylenes, ndi zinthu zina zosakhazikika zapezeka m'nthaka ndi pansi pa nthaka pafupi ndi malo ambiri osungiramo madzi (US EPA 1989a,b).Kramer(1989) adawunika kuchuluka kwa exposuresto benzene pochotsa, kuyeretsa, kupopa, ndi kuyesa matanki osungiramo mafuta apansi pansi.Nthawi zambiri anthu amakhala ndi 0.43-3.84 ppm (mu maola 1.5-6) ​​ndipo nthawi yayitali kwambiri (15-minute) anali 9.14 ppm.Benzene imapezekanso mu fodya (Hoffmann et al. 1989);motero chiwopsezo cha kukhudzidwa kwake chikhoza kuwonjezeka chifukwa chokoka utsi wotero.
    Benzene amagwiritsidwa ntchito ngati chosungunulira cha sera, utomoni, ndi mafuta;monga chochotsera utoto;monga diluentfor lacquers;popanga utoto, mankhwala, ma vanishi ndi linoleum; komanso ngati zinthu zopangira kupanga mitundu ingapo ya organic.

    MMENE MUNGAGULE KWA IFE

    Chemwin ikhoza kupereka ma hydrocarbon ambiri ambiri ndi zosungunulira zamankhwala kwa makasitomala aku mafakitale.Izi zisanachitike, chonde werengani mfundo zotsatirazi zokhuza kuchita bizinesi nafe: 

    1. Chitetezo

    Chitetezo ndicho chofunikira kwambiri chathu.Kuphatikiza pa kupatsa makasitomala chidziwitso chokhudza kugwiritsa ntchito bwino komanso kusamala zachilengedwe kwa zinthu zathu, tadziperekanso kuwonetsetsa kuti chiwopsezo chachitetezo cha ogwira ntchito ndi makontrakitala chikuchepetsedwa kukhala chocheperako komanso chotheka.Choncho, tikufuna kuti kasitomala awonetsetse kuti miyezo yoyenera yotsitsa ndi kusunga chitetezo ikukwaniritsidwa tisanaperekedwe (chonde onani zowonjezera za HSSE pazogulitsa zomwe zili pansipa).Akatswiri athu a HSSE atha kupereka chitsogozo pamiyezo iyi.

    2. Njira yobweretsera

    Makasitomala amatha kuyitanitsa ndikutumiza zinthu kuchokera ku chemwin, kapena atha kulandira zinthu kuchokera kumakampani athu opanga.Njira zoyendera zomwe zilipo zikuphatikiza magalimoto, njanji kapena ma multimodal (mikhalidwe yosiyana imagwira ntchito).

    Pankhani ya zofuna za makasitomala, titha kufotokoza zofunikira za mabwato kapena akasinja ndikugwiritsa ntchito miyezo yapadera yachitetezo / kuwunika ndi zofunikira.

    3. Kuchuluka kwa dongosolo lochepa

    Ngati mumagula zinthu patsamba lathu, kuchuluka kwa madongosolo ocheperako ndi matani 30.

    4.Kulipira

    Njira yolipirira yokhazikika imachotsedwa mwachindunji mkati mwa masiku 30 kuchokera pa invoice.

    5. Zolemba zotumizira

    Malemba otsatirawa amaperekedwa pakubweretsa kulikonse:

    · Bill of Lading, CMR Waybill kapena chikalata china chamayendedwe

    · Satifiketi Yowunikira kapena Yogwirizana (ngati pakufunika)

    · Zolemba zokhudzana ndi HSSE mogwirizana ndi malamulo

    · Zolemba za kasitomu mogwirizana ndi malamulo (ngati pakufunika)
