    NA WAIWAI KEMIIKA

    ʻO Benzene kahi wai maʻemaʻe, ʻoluʻolu, kala ʻole, ʻaʻa loa me ka ʻala ʻoluʻolu.He hydrocarbon aromatic ia e paila ana ma 80.1 DC.Hoʻohana ʻia ʻo Benzene ma ke ʻano he mea hoʻoheheʻe i nā wahi he nui o nā ʻoihana, e like me ka hana ʻana i ka ʻōpala a me nā kāmaʻa, a i ka hana ʻana i nā mea nui ʻē aʻe, e like me styrene, phenol, a me cyclohexane.He mea nui ia i ka hana ʻana i nā mea holoi, pesticides, solvents, a me nā mea wehe pena.Aia ia i loko o nā wahie e like me ka ʻaila a hiki i ka pae o 5%.

    He wai ʻaʻala a ʻaʻole waihoʻoluʻu a i ʻole melemele māmā me ka ʻala ʻala, ʻala, phenolic a i ʻole ka ʻala e like me ka ʻaila.Ma 40 ° C, ua hoʻoholo ʻia kahi ʻano paepae ʻala o 190 μg / L i ka ea e Young et al.(1996).Ua hoʻoholo ʻia kahi paepae ʻala o 4.68 ppmv e Leonardos et al.(1969).Ua hōʻike ʻia e Punter (1983) kahi ʻike paepae ʻala o 108 mg/m3 (34 ppmv).ʻO ka awelika hiki ke ʻike ʻia nā paepae ʻala i ka wai ma 60 °C a ma ka lewa ma 40 °C he 0.072 a me 0.5 mg/L, kēlā me kēia.

    Hoʻololi pū ʻia ʻo Benzene i cyclohexane, kahi i hoʻohana ʻia e hana ai i nā nylon a me nā fiber synthetic.

    Loaʻa ka Benzene i loko o ka lanahu a me ka lanahu-tar distillationproducts a me nā huahana petroleum e like me ka ʻaila.Loaʻa ia i loko o nā kinoea a me nā leachates o nā ʻōpala ʻāina no nā ʻōpala ʻoihana, nā ʻōpala hana, a me nā hoʻolele ʻāina (Oak Ridge National Laboratory 1989).Ua ʻike ʻia ka nui o nā benzene, toluene, xylenes, a me nā mea ola kino ʻē aʻe i loko o ka lepo a me ka wai o ka lepo ma kahi kokoke i nā ʻāina hoʻomaʻemaʻe he nui (US EPA 1989a,b).Ua loiloi ʻo Kramer (1989) i ke kiʻekiʻe o ka hoʻolaha ʻana i ka benzene i ka wā o ka wehe ʻana, ka hoʻomaʻemaʻe ʻana, ka paila ʻana, a me ka hoʻāʻo ʻana i nā pahu mālama ʻaila ma lalo o ka honua.ʻO ka awelika o nā hōʻike kanaka he 0.43-3.84 ppm (ma 1.5-6 mau hola) a ʻo ka hōʻike kiʻekiʻe loa o ka wā pōkole (15-minuke) ʻo 9.14 ppm.Loaʻa ka Benzene i loko o ka paka (Hoffmann et al. 1989);no laila, hiki ke ho'onui 'ia ka pilikia o ka 'ike 'ana mai ke komo 'ana i ia uahi.
    Hoʻohana ʻia ʻo Benzene ma ke ʻano he solvent no nā waxes, resins, a me nā aila;e like me ka mea wehe pena;e like me ka mea hoʻoheheʻe no nā lacquers;i ka hana ʻana i nā mea pena, nā lāʻau lapaʻau, nā varnish, a me ka linoleum; a ma ke ʻano he mea maka no ka hana ʻana i nā pūhui organik.

    Pehea e kūʻai mai ai iā mākou

    Hiki iā Chemwin ke hāʻawi i ka nui o nā hydrocarbons nui a me nā mea hoʻoheheʻe kemika no nā mea kūʻai aku ʻoihana.Ma mua o kēlā, e heluhelu i ka ʻike kumu e pili ana i ka hana ʻana me mākou: 

    1. Palekana

    ʻO ka palekana kā mākou mea nui.Ma waho aʻe o ka hāʻawi ʻana i nā mea kūʻai aku i ka ʻike e pili ana i ka hoʻohana palekana a me ka hoʻohana ʻana i ka nohona o kā mākou huahana, ua paʻa pū mākou i ka hōʻoia ʻana e hōʻemi ʻia nā pilikia palekana o nā limahana a me nā mea hana ʻaelike i kahi liʻiliʻi kūpono a hiki.No laila, koi mākou i ka mea kūʻai aku e hōʻoia i ka hoʻokō ʻana i nā kūlana palekana kūpono no ka wehe ʻana a me ka mālama ʻana ma mua o kā mākou hoʻouna ʻana (e ʻoluʻolu e nānā i ka appendix HSSE ma nā ʻōlelo a me nā kūlana kūʻai ma lalo).Hiki i kā mākou mau loea HSSE ke hāʻawi i ke alakaʻi i kēia mau kūlana.

    2. Keʻano hoʻouna

    Hiki i nā mea kūʻai ke kauoha a hāʻawi i nā huahana mai chemwin, a i ʻole hiki iā lākou ke loaʻa nā huahana mai kā mākou hale hana.ʻO nā ʻano kaʻa kaʻa i loaʻa ke kaʻa kaʻa, kaʻaahi a i ʻole ka halihali multimodal (e pili ana nā kūlana kaʻawale).

    I ka hihia o nā koi o ka mea kūʻai aku, hiki iā mākou ke kuhikuhi i nā koi o nā moku a i ʻole nā ​​pahu pahu a kau i nā kūlana palekana / loiloi kūikawā a me nā koi.

    3. Ka nui kauoha liʻiliʻi

    Inā kūʻai ʻoe i nā huahana mai kā mākou pūnaewele, ʻo ka liʻiliʻi liʻiliʻi he 30 tons.

    4. Uku

    ʻO ke ala uku maʻamau ka unuhi pololei ʻana i loko o 30 mau lā mai ka invoice.

    5. Nā palapala hoʻouna

    Hāʻawi ʻia kēia mau palapala i kēlā me kēia hoʻouna:

    · Bill of Lading, CMR Waybill a i ʻole nā ​​palapala halihali e pili ana

    · Palapala hōʻoia o ka nānā ʻana a i ʻole Conformity (inā koi ʻia)

    · Nā palapala pili i ka HSSE e like me nā lula
