Khoom npe:Diethylene glycol
Molecular hom:C4H10O3
CAS Nr:111-46-6 : kuv
Cov khoom siv molecular:
Diethylene glycol yog cov xim tsis muaj xim, tsis muaj ntxhiab thiab ruaj khov oily kua. Nws kuj yog me ntsis viscous, noncorrosive thiab nonvolatile. Vim nws cov ether thiab cawv pawg, diethylene glycol nthuav tawm cov khoom siv tshuaj lom neeg ntawm ob qho tib si thawj cawv thiab ethers. Nws cov ntsiab lus kub kub yog qhov siab dua li ntawm ethylene glycol, thiab nws cov kuab tshuaj ntau dua. Diethylene glycol yog miscible nrog dej, ethers, qis aliphatic cawv, aldehydes thiab ketones thiab yog ib nrab soluble hauv benzene, carbon tetrachloride, monobenzene, orthodichlorobenzene thiab toluene. Nws dissolves ntau dyes, resins, roj, nitrocellulose thiab ntau cov organic tshuaj. Vim nws cov kuab tshuaj muaj zog, tsis tshua muaj volatility thiab hygroscopicity, nws yog siv nyob rau hauv textile lubricants, txiav roj, qhuav ntxuav xab npum, luam ntawv inks, steam-set inks, thiab nongrain ntoo stains. Hauv kev lag luam textile diethylene glycol yog siv los ua tus neeg sawv cev rau cov ntaub plaub, rayon, thiab paj rwb. Raws li ib qho hnyav rau dyes nws ua rau muaj txiaj ntsig zoo hauv dyeing thiab luam ntawv. Lub siab hygroscopicity ntawm diethylene glycol ua rau nws ua tau zoo softening tus neeg sawv cev rau luam yeeb, ntawv, hluavtaws sponges, glues thiab casein. Diethylene glycol yog tshwj xeeb tshaj yog pab tau nyob rau hauv lub cev qhuav dej ntawm natural gas. Kev sib xyaw ntawm diethylene glycol thiab monoethanolamine yuav tshem tawm cov dej noo, hydrogen sulfide thiab carbon dioxide los ntawm cov nkev.
Nyob rau hauv cov tshuaj tiv thaiv kab mob rau lub tshuab nqus dej, cov dej ntsaws rau hauv lub tank roj, thiab lwm yam (dej nrog 40% diethylene glycol khov ntawm -18 °; nrog 50% ntawm -28 °); raws li lubricating thiab xov tus neeg sawv cev rau wool, worsted, paj rwb, rayon, thiab txhob lo lo ntxhuav; raws li hnyav rau vat dyes; nyob rau hauv muaj pes tsawg leeg corks, kua nplaum, gelatin, casein, thiab pastes kom tsis txhob qhuav tawm.
Diethylene glycol yog xim tsis muaj xim, tsis muaj ntxhiab, ntshiab kua. Nws yog miscible nrog dej hauv txhua qhov sib piv. Nws muaj ntau yam kev lag luam siv. Nws yog ib feem ntawm antifreeze, nres kua, tshuaj pleev ib ce, inks, thiab ziab khaub ncaws, thiab nws yog siv raws li ib tug plasticizer.
Diethylene glycol (DEG) yog cov khoom siv hnyav thiab muaj nyob hauv ntau cov khoom lag luam. Nws yog siv los ua tus neeg ua kom lub cev qhuav dej rau kev ua cov nkev; raws li lub lubricating thiab xov tus neeg sawv cev rau textiles; ib qho tseem ceeb hauv cov kua dej nres, cov roj nplua nyeem, cov tshuaj tiv thaiv kab mob, cov ntawv ntsa strippers thiab hauv kev daws teeb meem pos huab; ib qho hnyav rau luam ntawv inks thiab textile dyes; thiab yog siv los ua ib qho nruab nrab hauv kev tsim khoom ntawm qee cov resins, triethylene glycol, surfactants, thiab diethylene glycol esters thiab ethers.
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)
