Dimethyl Formamide/DMF Tayada Xasilloon iyo Qiimaha Tartanka
Codsiga
Dimethyl formamide (DMF) waa walax kiimiko ceeriin ah oo muhiim ah iyo dareere aad u fiican, oo inta badan loo isticmaalo polyurethane, acrylic, daawooyinka, sunta cayayaanka, rinjiyeynta, elektarooniga iyo warshadaha kale. Waxaa lagu dhaqay warshadaha polyurethane sidii wakiil bogsiin ah, waxaana inta badan loo isticmaalaa soo saarista maqaar qoyan oo macmal ah; daawooyinka macmal ah ee warshadaha dawooyinka sida dhexdhexaad, si weyn loogu isticmaalo diyaarinta doxycycline, cortisone, wax soo saarka daawada sulfa; warshadaha acrylic looxa wareegga deminta sida dareere inta badan loo isticmaalo wax soo saarka acrylic qalalan ee wareegga; warshadaha sunta cayayaanka si loo sameeyo sunta sare iyo sunta yar ee sunta; rinjiyeynta warshadaha rinjiga sida dareere; qaybaha qasacadaysan ee warshadaha elektaroonigga sida nadiifinta, iwm.; warshadaha kale, oo ay ku jiraan side gaasaska khatarta ah, kiristaalka dawooyinka iyadoo la isticmaalayo dareere.

Kaydinta
Maadaama Dimethyl Formamide (DMF) uu yahay kiimiko dabiici ah oo leh sifooyin guban kara oo isbeddeli kara, qodobbada soo socda waa in la xuso inta lagu jiro kaydinta:
1. Deegaanka kaydinta: DMF waa in lagu kaydiyaa jawi qabow, qalalan oo hawo fiican leh, lagana fogaadaa qorraxda tooska ah iyo heerkulka sare. Meesha lagu kaydiyo waa inay ka fogaataa dabka, kulaylka iyo oksaydhka, goobaha aan qarxin.
2. Baakadaha: DMFS waa in lagu kaydiyaa weelal aan hawo lahayn oo tayo deggan leh, sida dhalooyinka galaaska, dhalooyinka balaastikada ah ama durbaanka birta ah. Waa in si joogto ah loo hubiyaa hufnaanta iyo adkaanta weelasha.
3. Ka hortag jahawareerka: DMF waa in aan lagu qasin oksaydh xooggan, aashito xooggan, saldhig xooggan iyo walxo kale si looga fogaado falcelinta khatarta ah. Inta lagu jiro kaydinta, rarista, dejinta iyo isticmaalka, waa in fiiro gaar ah la siiyaa si looga hortago isku dhaca, is jiidjiidka iyo gariirka, si looga fogaado daadashada iyo shilalka.
4. Ka hortagga korontada taagan: Kaydinta DMF, rarista, dejinta iyo isticmaalka habka, waa inay ka hortagtaa soo saarista korontada taagan. Tallaabooyin ku habboon waa in la qaadaa, sida dhulka, dahaarka, qalabka ka hortagga istaagga, iwm.
5. Aqoonsiga calaamadda: Weelasha DMF waa in lagu calaamadeeyaa calaamado iyo aqoonsi cad, taasoo tilmaamaysa taariikhda kaydinta, magaca, xoogga, tirada iyo macluumaad kale, si loo fududeeyo maaraynta iyo aqoonsiga.
