Dimethyl Formamide/DMF Ubwino Wokhazikika Ndi Mtengo Wopikisana
Kugwiritsa ntchito
Dimethyl formamide (DMF) ndi mankhwala ofunikira kwambiri komanso chosungunulira chabwino kwambiri, chomwe chimagwiritsidwa ntchito kwambiri mu polyurethane, acrylic, mankhwala, mankhwala ophera tizilombo, utoto, zamagetsi ndi mafakitale ena. Chotsukidwa mumakampani opanga polyurethane ngati chotsukira, chimagwiritsidwa ntchito kwambiri popanga chikopa chonyowa; mankhwala opangidwa mumakampani opanga mankhwala ngati zinthu zosakaniza, zomwe zimagwiritsidwa ntchito kwambiri popanga doxycycline, cortisone, ndi mankhwala a sulfa; makampani opanga acrylic bolodi lozimitsa ngati chosungunulira lomwe limagwiritsidwa ntchito kwambiri popanga acrylic dry spinning; makampani opanga mankhwala ophera tizilombo kuti apange mankhwala ophera tizilombo omwe amagwira ntchito bwino komanso otsika poizoni; utoto mumakampani opanga utoto ngati chosungunulira; zigawo zophimbidwa mumakampani opanga zamagetsi ngati zotsukira, ndi zina zotero; mafakitale ena, kuphatikiza chonyamulira mpweya woopsa, kupanga makristalo a mankhwala pogwiritsa ntchito zosungunulira.

Malo Osungirako
Popeza Dimethyl Formamide (DMF) ndi mankhwala achilengedwe omwe amatha kuyaka komanso kusinthasintha, mfundo zotsatirazi ziyenera kukumbukiridwa mukasunga:
1. Malo osungira: DMF iyenera kusungidwa pamalo ozizira, ouma komanso opumira bwino, kupewa kuwala kwa dzuwa mwachindunji komanso kutentha kwambiri. Malo osungira ayenera kukhala kutali ndi malo oyaka moto, kutentha ndi zinthu zowononga okosijeni, zomwe sizingaphulike.
2. Kupaka: DMFS iyenera kusungidwa m'zidebe zosalowa mpweya zomwe zili ndi khalidwe lokhazikika, monga mabotolo agalasi, mabotolo apulasitiki kapena ng'oma zachitsulo. Kulimba ndi kulimba kwa zidebe kuyenera kuyang'aniridwa nthawi zonse.
3. Pewani chisokonezo: DMF siyenera kusakanikirana ndi oxidant wamphamvu, asidi wamphamvu, maziko amphamvu ndi zinthu zina kuti tipewe zotsatira zoopsa. Posungira, kukweza, kutsitsa ndi kugwiritsa ntchito, chisamaliro chiyenera kuperekedwa kuti tipewe kugundana, kukangana ndi kugwedezeka, kuti tipewe kutuluka kwa madzi ndi ngozi.
4. Kuletsa magetsi osasinthasintha: Posungira, kukweza, kutsitsa ndi kugwiritsa ntchito DMF, magetsi osasinthasintha ayenera kupewedwa. Njira zoyenera ziyenera kutengedwa, monga kuyika pansi, kuphimba, zida zotsutsana ndi magetsi osasinthasintha, ndi zina zotero.
5. Kuzindikira chizindikiro: Zidebe za DMF ziyenera kukhala ndi zilembo zomveka bwino komanso zodziwika bwino, zomwe zikusonyeza tsiku losungira, dzina, kuchuluka kwake, kuchuluka kwake ndi zina zambiri, kuti zithandize kuyang'anira ndi kuzindikira.
