Dimethyl Formamide/DMF Tayada Deggan iyo Qiimaha Tartanka
Codsiga
Dimethyl formamide (DMF) oo ah walxo kiimiko oo muhiim ah iyo dareere aad u fiican, oo inta badan loo isticmaalo polyurethane, acrylic, farmashiyaha, sunta cayayaanka, midabada, elektiroonigga iyo warshadaha kale. Waxaa lagu dhaqay warshadaha poliurethane sida wakiilka daaweynta, inta badan waxaa loo isticmaalaa soo saarista maqaarka qoyan ee qoyan; dawooyinka synthetic ee warshadaha dawooyinka sida dhexdhexaadinta, oo si ballaaran loo isticmaalo diyaarinta doxycycline, cortisone, soosaarka daroogada sulfa; warshadaha akril, looxa wareegga deminaya sida dareere inta badan loo isticmaalo wax soo saarka qalalan akrilik; warshadaha sunta cayayaanka loogu talagalay isku-dhafka waxtarka sare leh iyo sunta sunta cayayaanka ee hooseeya; dheehin warshadaha dheeha sida dareere ah; qaybaha qasacadaysan ee warshadaha elektiroonigga ah sida nadiifinta, iwm; warshado kale, oo ay ku jiraan sidaha gaasaska khatarta ah, crystallization daawada isticmaalaya dareere.

Kaydinta
Sida Dimethyl Formamide (DMF) ay tahay kiimiko dabiici ah oo leh hanti gubanaysa oo kacsan, qodobbada soo socda waa in la xuso inta lagu jiro kaydinta:
1. Bey'adda Kaydinta: DMF waa in lagu kaydiyaa meel qabow, qalalan oo hawo wanaagsan leh, iska ilaali iftiinka qorraxda tooska ah iyo heerkulka sare. Meesha wax lagu kaydiyo waa in ay ka fogaato dabka, kulaylka iyo oxidant, meelaha aan qarxin.
2. Baakadaha: DMFS waa in lagu kaydiyaa weel aan hawo lahayn oo tayo leh, sida dhalooyinka dhalooyinka, caagagga ama durbaanka birta ah. Daacadnimada iyo adkaanta weelasha waa in si joogto ah loo hubiyo.
3. Kahortagga jaahwareerka: DMF waa in aan lagu qasin oksidant xooggan, aashito xoog leh, saldhig adag iyo walxo kale si looga fogaado falcelinta khatarta ah. Inta lagu jiro habka kaydinta, rarista, dejinta iyo isticmaalka, waa in fiiro gaar ah loo yeesho si looga hortago isku dhaca, isku dhaca iyo gariirka, si looga fogaado daadinta iyo shilalka.
4. Ka hortag koronto taagan: Kaydinta DMF, rarista, dejinta iyo habka isticmaalka, waa inay ka hortagtaa abuurista koronto taagan. Tallaabooyin ku habboon waa in la qaadaa, sida dhulka, dahaarka, qalabka lidka ku ah, iwm.
5. Aqoonsiga summada: weelasha DMF waa in lagu calaamadiyaa calaamado cad iyo aqoonsi, oo muujinaya taariikhda kaydinta, magaca, xoogga saarida, tirada iyo macluumaadka kale, si ay u fududaato maareynta iyo aqoonsiga.
