Khoom npe:Tetrahydrofuran
Molecular hom:C4H8O
CAS Nr:109-99-9 ib
Cov khoom siv molecular:
Tetrahydrofuran (THF) yog cov kua tsis muaj xim, tsis muaj kuab lom nrog cov ntxhiab tsw ntxhiab tsw ntxhiab lossis acetonelike thiab muaj miscible hauv dej thiab cov kuab tshuaj organic feem ntau. Kev khaws cia ntev ntev hauv kev sib cuag nrog huab cua thiab thaum tsis muaj cov tshuaj tiv thaiv antioxidant tuaj yeem ua rau THF decompose rau hauv tawg peroxides.
Tetrahydrofuran yog siv rau hauv kev tsim cov polymers nrog rau kev ua liaj ua teb, tshuaj, thiab khoom siv tshuaj. Kev tsim khoom lag luam feem ntau tshwm sim hauv cov kaw lus kaw lossis hauv kev tswj xyuas engineering uas txwv cov neeg ua haujlwm raug thiab tso tawm rau ib puag ncig. THF kuj tseem siv los ua cov kuab tshuaj (xws li, cov yeeb nkab haum) uas yuav ua rau muaj kev cuam tshuam ntau dua thaum siv hauv qhov chaw kaw tsis muaj qhov cua txaus. Txawm hais tias THF yog ib txwm muaj nyob rau hauv kas fes aroma, floured chickpeas, thiab siav nqaij qaib, natural exposures tsis tau xav tias yuav ua rau muaj teeb meem loj.
Butylene oxide yog siv los ua fumigant thiab inadmixture nrog lwm cov tebchaw. Nws yog siv los stabilize roj nrog rau cov xim thiab sludge tsim.
Tetrahydrofuran yog siv los ua ib qho hnyav forresins, vinyls, thiab siab polymers; raws li Grignardreaction nruab nrab rau organometallic, thiab hlau hydride tshua; Thiab nyob rau hauv lub synthesis ntawm succinic acid thiab butyrolactone.
Tetrahydrofuran yog siv feem ntau (80%) los ua polytetramethylene ether glycol, lub hauv paus polymer siv feem ntau hauv kev tsim cov elastomeric fibers (xws li, spandex) nrog rau polyurethane thiab polyester elastomers (xws li, tawv tawv, skateboard log). Cov seem (20%) yog siv rau hauv cov ntaub ntawv hnyav (xws li, yeeb nkab cements, adhesives, luam ntawv inks, thiab sib nqus daim kab xev) thiab ua cov tshuaj tiv thaiv hnyav hauv tshuaj thiab tshuaj syntheses.
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)
