Kapangidwe ka maselo:
Trichlorethylene (TCE) ndi madzi owoneka bwino, opanda mtundu, osayaka (pachipinda chotentha) chokhazikika chapoizoni chokhala ndi fungo la chloroform (ATSDR, 2011). Amasungunuka pang'ono m'madzi, amasungunuka mumafuta ndi zosungunulira wamba, ndipo amawira pa 87°C (190 F).
Ikakhudzana ndi mpweya, imawola pang'onopang'ono ndikupanga phosgene, hydrogen chloride, ndi dichloroacetyl chloride. Trichlorethylene ikakumana ndi madzi imakhala yowononga ndikupanga dichloroacetic acid ndi hydrochloric acid. Amasungunuka mu methanol, diethyl ether, ndi acetone.
Trichlorethylene imadziwikanso kuti trichloroethene, acetylene trichloride, 1-chloro-2,2- dichlorethylene, ndi ethylene trichloride, ndipo imafupikitsidwanso kuti TRI. Ndiwosakhazikika, wothira chlorinated organic hydrocarbon yomwe imagwiritsidwa ntchito kwambiri pochotsa zitsulo komanso ngati hydrofluorocarbon (HFC-134a) yapakatikati (ATSDR, 2013). Amagwiritsidwanso ntchito popanga zomatira, zochotsa utoto, utoto, zokometsera, ndi ma vanishi. M’zaka za m’ma 1930, TCE inayambitsidwa kuti igwiritsidwe ntchito poyeretsa, koma mchitidwe umenewu unathetsedwa kwambiri m’zaka za m’ma 1950 pamene TCE inasinthidwa ndi tetrachlorethylene (PCE). Ili ndi zina zambiri zomwe zimagwiritsidwa ntchito m'mbuyomu muzodzola, mankhwala, zakudya, ndi mankhwala ophera tizilombo (US EPA, 2011). Ndi zowononga zachilengedwe zomwe zapezeka mumlengalenga, pansi pa nthaka, madzi apamtunda, ndi nthaka
Trichlorethylene imagwiritsidwa ntchito ngati zosungunulira, mu drycleaning, mu degreasing, komanso osagwiritsa ntchito pang'ono ngati opaleshoni ya opaleshoni.
Chlorinated hydrocarbon yomwe imagwiritsidwa ntchito ngati chotsukira kapena chosungunulira zitsulo, mafuta, utomoni, sulfure komanso ngati chotsitsa chamtengo wapatali. Zingayambitse kukhudzana ndi dermatitis, generalized exanthema, Stevens-Johnson syndrome, pustular kapena bullous eruption ndi scleroderma.
Zosungunulira zamafuta, phula, utomoni, mafuta, labala, utoto, ndi vanishi. Zosungunulira za cellulose esters ndi ethers. Amagwiritsidwa ntchito pochotsa zosungunulira m'mafakitale ambiri. Mu degreasing, mu youma kuyeretsa. Popanga mankhwala achilengedwe, mankhwala, monga chloroacetic acid.
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)
