Dimethyl Formamide/DMF Ubwino Wokhazikika Ndi Mtengo Wopikisana
Kugwiritsa ntchito
Dimethyl formamide (DMF) ngati chinthu chofunikira kwambiri chopangira mankhwala komanso zosungunulira zabwino kwambiri, zomwe zimagwiritsidwa ntchito kwambiri mu polyurethane, acrylic, pharmaceuticals, mankhwala ophera tizilombo, utoto, zamagetsi ndi mafakitale ena. Kutsukidwa mu makampani polyurethane monga kuchiritsa wothandizira, zimagwiritsa ntchito kupanga chonyowa chikopa kupanga; mankhwala kupanga mu makampani mankhwala monga intermediates, ankagwiritsa ntchito yokonza doxycycline, cortisone, sulfa kupanga mankhwala; acrylic makampani quenching dera bolodi monga zosungunulira makamaka ntchito akiliriki youma kupota kupanga; makampani ophera tizilombo popanga zida zapamwamba komanso mankhwala otsika kawopsedwe; dyesin makampani opanga utoto monga zosungunulira; zitini mu makampani zamagetsi monga kuyeretsa, etc.; mafakitale ena, kuphatikizapo chonyamulira cha mpweya oopsa, mankhwala crystallization ntchito zosungunulira.

Kusungirako
Popeza Dimethyl Formamide (DMF) ndi mankhwala achilengedwe omwe amatha kuyaka komanso kusakhazikika, mfundo zotsatirazi ziyenera kudziwidwa posungira:
1. Malo osungira: DMF iyenera kusungidwa pamalo ozizira, owuma komanso mpweya wabwino, kupewa kuwala kwa dzuwa ndi kutentha kwakukulu. Malo osungiramo ayenera kukhala kutali ndi moto, kutentha ndi okosijeni, malo osaphulika.
2. Kupaka: DMFS iyenera kusungidwa m'mitsuko yopanda mpweya yamtundu wokhazikika, monga mabotolo agalasi, mabotolo apulasitiki kapena ng'oma zachitsulo. Umphumphu ndi kulimba kwa zotengera ziyenera kufufuzidwa nthawi zonse.
3. Pewani chisokonezo: DMF sayenera kusakanikirana ndi oxidant amphamvu, asidi amphamvu, maziko amphamvu ndi zinthu zina kuti apewe zoopsa. Posungira, kutsitsa, kutsitsa ndikugwiritsa ntchito, chidwi chiyenera kulipidwa kuti tipewe kugunda, kugwedezeka ndi kugwedezeka, kupewa kutayikira ndi ngozi.
4. Pewani magetsi osasunthika: Posungirako DMF, kutsitsa, kutsitsa ndi kugwiritsa ntchito njira, kuyenera kuletsa kupanga magetsi osasunthika. Njira zoyenera ziyenera kuchitidwa, monga kuyika pansi, zokutira, zida za antistatic, etc.
5. Chizindikiritso cha zilembo: Zotengera za DMF ziyenera kulembedwa ndi zilembo zomveka bwino komanso zizindikiritso, kuwonetsa tsiku losungirako, dzina, ndende, kuchuluka kwake ndi zidziwitso zina, kuti athe kuwongolera kasamalidwe ndi kuzindikira.
