Kusunga
Monga Dimethyl Lormeamide (DMF) ndi mankhwala ochitira zachilengedwe ndi katundu woyaka komanso wosasunthika, mfundo zotsatirazi ziyenera kudziwika panthawi yosungira:
1. Malo osungira: DMF iyenera kusungidwa pamalo abwino, owuma komanso ozizira komanso opumira, pewani kuwala kwa dzuwa ndi kutentha kwambiri. Malo osungiramo ayenera kukhala kutali ndi moto, kutentha ndi malo osungirako mabasi, ophulika.
2. Paketi: DMFS iyenera kusungidwa m'matumba okhazikika, monga mabotolo agalasi, mabotolo apulasitiki kapena mabotolo achitsulo. Kukhulupirika ndi kulimba kwa ziweto ziyenera kuyesedwa pafupipafupi.
3. Pewani chisokonezo: DMF sayenera kusakanikirana ndi oxidant yamphamvu, yamphamvu, maziko amphamvu ndi zinthu zina kuti mupewe kuchita zoopsa. Pakakhala zosungirako, kunyamula, kutsegula ndikugwiritsa ntchito, chidwi chiyenera kulipidwa kuti chiteteze, kugwedezeka ndi kugwedezeka, kupewa kutayikira ndi ngozi.
4. Pewani magetsi osokoneza bongo: Kusungira kwa DMF, Kutsegula, Kutsitsa ndikugwiritsa ntchito, kuyenera kuletsa m'badwo wamagetsi. Njira zoyenera ziyenera kutengedwa, monga kufooka, zokutira, zida za Antistritic, etc.
5. Chidziwitso cha zilembo: DMF mumiyendo ziyenera kulembedwa ndi zilembo zomveka bwino komanso kuzindikiritsa, zomwe zikuwonetsa deti yosungirako, dzina, chidziwitso komanso chidziwitso.
