Zosankha Zogulitsa:
Benzene ndiomveka, wopanda utoto, wopanda utoto, woyamwa kwambiri wokhala ndi fungo labwino komanso lodziwika bwino. Ndi ma hydcarborn onunkhira omwe zithupsa pa 80.1 DC. Benzene imagwiritsidwa ntchito ngati zosungunulira m'malo ambiri mafakitale, monga kupanga mphira wa mphira ndi nsapato, ndipo popanga zinthu zina zofunika, zozungulira, ndi cyclohexane. Ndikofunikira pakupanga zotupa, mankhwala ophera tizilombo, ma sol sol, ndi penti. Imapezeka pamafuta monga mafuta mpaka 5%.
Chomveka, chowoneka bwino ku madzi owala madzi ndi fungo labwino, loyenera, zinthu kapena zonunkhira ngati mafuta ngati mafuta. Pa 40 ° C, cholowera cha fungo la Sourm 190 μg / l mlengalenga lidatsimikizika ndi achinyamata et al. (1996). Cholinga cha fungo la 4.68 ppmv adatsimikiziridwa ndi Leonardos et al. (1969). Kuwala kwa fungo la kununkhira kwa 108 mg / m3 (34 ppmv) adanenedwa ndi punter (1983). Njira yapakati yopepuka yopepuka yotsika m'madzi pa 60 ° C ndi mlengalenga pa 40 ° C anali 0,072 ndi 0,5 mg / l, motsatana.
Benzene imasinthidwanso ndi cyclohexane, yomwe imagwiritsidwa ntchito kupanga nayoloni ndi ulusi wokongoletsa.
Benzene imachitika mu malasha ndi milandu ya malasha ndi ma petroleum mankhwala Amatuwas. Amapezekanso m'matumba a masitani a masitepe a masitepe a mafakitale, zinyalala zomanga, ndi zinyalala zoyatsira (Oak Ridge National Laborator 1989). Kuchitapo kanthu kwa Benzene, Toluene, Xylenes, andleornes osasunthika apezeka akusungunuka nthaka ndi zifukwa zokhala ndi Anopa 1989a, b). Kramer (1989) adawunikira kuchuluka kwa zowonjezera pakuchotsa, kuyeretsa, kupopa, kupondapo, ndi kuyesa kwa pansi pamwala. Pafupifupi anthu owonjezera a anthu 0.43-3.84 ppm (mu 1.5-6 maola) ndi mphindi 15.14 ppm. Benzene amapezekanso mu fodya (hoffmann et al. 1989); Chifukwa chake kuopa kuopsa kwake kumatha kupitirira musupe wa insungsuch.
Benzene imagwiritsidwa ntchito ngati zosungunulira ya mafinya, ma rewini, ndi mafuta; monga utoto; ngati mabungwe achangu; Popanga utoto, ma prormaceuticals, varnisals, ndi linoleum; komanso monga cholembera kuti apange mankhwala ochulukirapo.
Chemin imatha kupereka mitundu yambiri ya hydrocarbons ndi sol sol solsomers mafakitale.Izi zisanachitike, chonde werengani zidziwitso zotsatila zokhudzana ndi kuchita bizinesi:
1. Chitetezo
Chitetezo ndichofunika kwambiri. Kuphatikiza pa kupereka makasitomala omwe ali ndi chidziwitso chokhudza malonda athu otetezeka komanso achilengedwe. Chifukwa chake, timafuna kasitomala kuti awonetsetse kuti njira zosungiramo zovomerezeka ndi zosungirako zimakumana ndisanakane (chonde onani zowonjezera zomwe zikuwoneka bwino) zomwe zikugulitsidwa pansipa). Akatswiri athu a hiby amatha kupereka chitsogozo pamalingaliro awa.
2. Njira yoperekera
Makasitomala amatha kuyitanitsa ndikupereka zinthu kuchokera ku chemwin, kapena amatha kulandira zinthu kuchokera ku chomera chathu chopanga. Njira zomwe zilipo zimaphatikizapo galimoto, njanji kapena zoyendera zingapo (malo osiyana).
Pankhani yofunikira makasitomala, titha kutchula zomwe zosewerera kapena akanki ndikugwiritsa ntchito malamulo apadera / zowunikira.
3. Kuchuluka kwa dongosolo
Ngati mungagule zinthu kuchokera patsamba lathu, kuchuluka kochepa kwa matani 30.
4.Pamment
Njira yolipira yolipira imachotsedwa mwachindunji patatha masiku 30 kuchokera ku invoice.
5. Zolemba
Zolemba zotsatirazi zimaperekedwa ndi kutumiza kulikonse:
· · · · · · · · · · · · · · · · · · · · · · · · · · · · · Phompho
Chikalata cha kusanthula kapena kusanthula (ngati kuli kofunikira)
Zolembedwa zokhudzana ndi malamulo
Zilembo zolembedwa ndi malamulo (ngati zikufunika)
