N,N-Dimethylformamide (DMF) ndi wosinthika wokhazikika komanso wogwiritsa ntchito kwambiri pantchito kuphatikiza gawo lambiri, malembo, ndi mafakitale a plastic. Mawonekedwe ake abwino kwambiri komanso kusiyanasiyana kosiyanasiyana ndi zinthu zosiyanasiyana ndi zinthu zazikulu zomwe zosungunulira zimadziwika. Mankhwala ndi opindulitsa kwambiri m'malo angapo monga polcemer, ndi kupanga zikopa ndi magwiridwe antchito a mankhwala.
Ali, Kugwiritsa kwake pa kukula kwakukulu kumatanthauza zovuta zambiri. Pomwe kuwopsa kwakukulu komanso chakuti ndikosavuta ndi zina mwazinthu zomwe n,N-dimethyfformide DMF imagwira, iyenera kusungidwa pansi pa zochitika zina, kunyamula molingana ndi malamulo, ndi antchito’ chitetezo chiyenera kutsimikiziridwa.
Pokhala bizinesi yomwe ili m'manja mwa omwe amadziwika kwambiri chifukwa chokhala methacryle methacrylate othandizira ndi China Hydroxybene, Cardicler imalimbikitsa kufunikira kwa chitetezo cha mankhwala pazaumboni zapadziko lonse lapansi. Bukulo limayambitsa chitetezo ndi udindo wa DMF kudzera maupangiri othandiza ndi kuwunikira.
Kodi n,N-Dimethylformamide (DMF)?
DMF ndi yomveka, Madzi opanda utoto okhala ndi fungo lodzikuza. Ndizolakwika ndi madzi komanso okhazikika, Kupangitsa kuti ikhale yopumira mu makenti a mankhwala, Kupanga mankhwala, ndikupanga kupanga.
Chemical Formula: C₃h₇no
Malo otentha: 153°C
Pophulikira: 58°C (Cup Cup)
Cas No.: 68-12-2
Mtengo wake wotsika komanso wowiritsa kwambiri umathandizira kuti ntchito yake ikhale yothandizana ndi kutentha kwa kutentha ndi chinyezi.
Zilonda zaumoyo ndi zachilengedwe
Ngakhale othandiza kwambiri, N,N-Dimethylformamide DMF imasankhidwa ngati poizoni ndi mphamvu ya carcinogenic:
- Kupweteka kapena khungu la khungu zitha kuyambitsa kuwonongeka kwa chiwindi, khungu kukwiya, ndi kubereka mozama ndi kulumikizana kwa nthawi yayitali.
- Mphamvu ya chilengedwe Mulinso zoopsa zam'madzi komanso kuipitsidwa kwa dothi.
Choncho, Makampani ogwiritsa ntchito DMF ayenera kukhazikitsa chitetezo choyenera kuti ateteze ogwira ntchito ndi chilengedwe.
Malangizo osungiramo chitetezo
Kusunga dmf mosamala:
- Gwiritsani ntchito dzimbiri zosapanga dzimbiri kapena rdpe
Pewani zofunda zazitsulo, omwe angayandikire. Onetsetsani kuti osungira amasindikizidwa kuti muchepetse mpweya wa VAPOR. - Sungani zozizira, Madera okhazikika
Sungani DMF kutali ndi magwero a kutentha, kuyatsa, ndi kuwala kwa dzuwa. Kutentha Kwambiri: 15-25 ° C. - Zolemba momveka bwino komanso mogwirizana ndi GHS
Zingwe zonse za DMF ziyenera kulembedwa ndi zizindikiro zowopsa, malangizo oyendetsera, ndi kulumikizana mwadzidzidzi. - Khazikitsani ma vapor
Kusunga Kwambiri, Kuwunikira kwa nthunzi ndikofunikira kudziwa kutaya kapena zoopsa zopitilira.
Kuyendetsa ndi kunyamula miyezo
DMF imayendetsedwa pansi pa Ndi 2265 gulu ngati chinthu chowopsa. Kuyendetsa DMF kumafuna:
- Kuvomerezedwa kosavomerezeka (ng'oma, Ibcc, ASO akasinja)
- Zolemba zoyenera, kuphatikizapo ma sheet a deta (SDS) ndi kunyamula chilolezo
- Kuphatikiza kuchokera ku zinthu zosagwirizana monga oxidizer ndi acid
Monga gawo la unyolo wathu, Madenga otsetsereka amawonetsetsa zonse za DMF pamgwirizano ndi Imdg, Eata, ndi adr miyezo, Kutumiza ndi zoyendera zamankhwala padziko lonse lapansi.
Malire ofotokozera ndi malingaliro a PPE
Mabungwe apadziko lonse lapansi akhazikitsa njira zowonekera kwa DMF:
| Nthambi | Malire ovomerezeka |
|---|---|
| OHE | 10 ppm (Kuwamba) |
| ACGIH | 10 ppm (Kuwamba); khungu |
| EU | 5 ppm (Kuwamba); khungu |
Zida zoteteza (PPE):
- Chyl rabara kapena magolovesi a Nitrile
- Makina ogwiritsa ntchito mankhwala
- Mankhwala okwanira a matenda a Epron kapena suti yoteteza
- Mpweya wabwino wazomwe umagwira ntchito m'malo antchito
Kuwongolera kwaumoyo nthawi zonse pa ntchito ya chiwindi kumalangizidwanso kwa ogwira ntchito nthawi yayitali ndi DMF.
Zochita zosasinthika ndi kuphatikiza kwa maunyolo opereka
Nthawi zina, Makasitomala amatha kufunafuna njira zina ku DMF chifukwa chowongolera kapena nkhawa. Madenga otsetsereka, ndi portfolio yake ngati Methyl Methacrylate Wogulitsa ndi China hydroxybenzene othandizira, imapereka njira zina zosinthika ndi mafomu ophatikizira kugwiritsa ntchito.
Timagwira ntchito limodzi ndi r&Magulu a D kuti ayesere magwiridwe antchito, chitetezo, ndikutsatira musanalowe kapena kuchepetsa kugwiritsa ntchito mapangidwe a DMF.
Chifukwa Chiyani Amasankha Kaland?
Ndi zaka zambiri zomwe zachitika pazachidziwitso bwino popanga mankhwala ndi kugawa padziko lonse, Madenga otsetsereka peleka:
- Kuyera Kwambiri N,N-Dimethylformamide DMF
- Kugwiritsa Ntchito Kupitilira 50 maiko
- Kutsatira kufikira, ISO, ndi miyezo ya GH
- Ntchito Zophatikiza Kuchokera Kumasintha Kuti Tisinthe
Kaya mukupanga kupanga kapena kukonza ma protocols ogwiritsira ntchito, Timapereka zoposa mankhwala - timapereka chidaliro.
