Acrylonitrile yog cov kua uas tsis muaj xim, flammable. Nws cov vapors tuaj yeem tawg thaum raug nplaim taws. Acrylonitrile tsis tshwm sim lawm. Nws yog tsim nyob rau hauv loj heev los ntawm ob peb chemical industries nyob rau hauv lub tebchaws United States, thiab nws yuav tsum tau thiab xav tau yog nce nyob rau hauv xyoo tas los no. Acrylonitrile yog ib qho ua tau hnyav, tsis muaj nitrile. Nws yog siv los ua lwm yam tshuaj xws li yas, hluavtaws roj hmab, thiab acrylic fibers. Nws tau siv los ua tshuaj tua kab fumigant yav dhau los; Txawm li cas los xij, tag nrho cov kev siv tshuaj tua kab tau raug txiav lawm. Cov tshuaj no yog cov tshuaj nruab nrab loj siv los tsim cov khoom lag luam xws li tshuaj, tshuaj tua kab mob antioxidants, thiab dyes, nrog rau cov organic synthesis. Cov neeg siv khoom loj tshaj plaws ntawm acrylonitrile yog cov kev lag luam chemical uas ua rau acrylic thiab modacrylic fibers thiab cov khoom siv siab ABS yas. Acrylonitrile kuj tseem siv rau hauv cov tshuab ua lag luam, lub nra, cov khoom siv, thiab kev tsim cov styrene-acrylonitrile (SAN) yas rau tsheb, khoom siv hauv tsev, thiab cov khoom ntim. Adiponitrile yog siv los ua nylon, dyes, tshuaj, thiab tshuaj tua kab.
Acrylonitrile yog siv nyob rau hauv zus tau tej cov acrylic fibers, resins, thiab nto txheej; raws li qhov nruab nrab hauv kev tsim tshuaj thiab dyes; raws li ib tug polymer modifier; thiab raws li ib tug fumigant. Nws yuav tshwm sim nyob rau hauv hluav taws-effluent gases vim pyrolyses ntawm polyacrylonitrile cov ntaub ntawv. Acrylonitrile tau pom tias tau tso tawm los ntawm acrylonitrile-styrene copolymer thiab acrylonitrile-styrene-butadiene copolymer fwj thaum cov fwj no tau ntim cov khoom noj-simulating cov kuab tshuaj xws li dej, 4% acetic acid, 20% ethanol, thiab heptane thiab khaws cia rau 10 hnub. mus rau 5 lub hlis (Nakazawa et al. 1984). Qhov kev tso tawm tau ntau dua nrog qhov kub thiab txias thiab yog tshwm sim los ntawm cov seem acrylonitrile monomer nyob rau hauv cov ntaub ntawv polymeric.
Acrylonitrile yog cov khoom siv raw siv rau kev sib txuas ntawm ntau cov hluavtaws fibers xws li Dralon thiab acrylic fibers. Nws kuj yog siv los ua tshuaj tua kab.
Kev tsim cov acrylic fibers. Nyob rau hauv lub plastics, txheej txheej, thiab adhesives industries. Raws li ib tug tshuaj intermediate nyob rau hauv lub synthesis ntawm antioxidants, pharmaceuticals, dyes, nto-active neeg sawv cev, thiab lwm yam. Nyob rau hauv cov organic synthesis los qhia ib pawg cyanoethyl. Raws li kev hloov pauv rau ntuj polymers. Raws li ib tug tshuaj tua kab fumigant rau khaws cia grain. Kev sim ua kom ua rau adrenal hemorrhagic necrosis hauv nas.
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 peb cov khoom, peb kuj tau cog lus los xyuas kom meej tias kev nyab xeeb ntawm cov neeg ua haujlwm thiab cov neeg cog lus raug txo qis rau qhov tsim nyog thiab ua tau yam tsawg kawg nkaus. Yog li, 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 cov 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 qhov yuav tsum tau 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.
4. Kev them nyiaj
Txoj kev them nyiaj tus qauv yog txiav tawm ncaj qha hauv 30 hnub txij li daim ntawv xa nyiaj.
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)
