Bakhaar
AS Dimithyl Mormamide (DMF) waa kiimiko dabiici ah oo leh guryaha guban kara oo kacsan, qodobbada soo socda waa in la ogaadaa inta lagu jiro kaydinta:
1. Deegaanka Kaydinta: DMF waa in lagu kaydiyaa jawi qabow, qalalan oo si fiican u qalalan, iska ilaali iftiinka qorraxda tooska ah iyo heerkulka sare. Meesha kaydinta waa inay ka fogaataa dabka, kuleylka iyo oksintat, tas-hiilaadka caddeynta.
2. Baakadaha: DMFS waa in lagu kaydiyaa weelasha hawada ee tayada xasilloonida, sida dhalooyinka dhalooyinka, dhalooyinka caagga ah ama durbaanka bir ah. Daacadnimada iyo adkaanta weelka waa in si joogto ah loo hubiyaa.
3. Ka hortag jahwareerka: DMF waa inaan lagu qasin xoog leh oksidant, aashito xoog leh, saldhig adag iyo walxo kale si looga fogaado ficil-celinta khatarta ah. Geedi socodka kaydinta, rarida, soo dejinta iyo isticmaalka, fiiro gaar ah waa in la bixiyaa si looga hortago shilalka, kala-baxa iyo gariirka, si looga fogaado baxsiga iyo shilalka.
4. Kahortaga korantada taagan: Kaydinta DMF, xamuulka, soo dejinta iyo adeegsiga hanaan, waa inay ka hortagtaa jiil koronto qaas ah. Tallaabooyin ku habboon waa in la qaataa, sida salka, daboolka, qalabka ka hortaga, iwm.
5. Aqoonsiga Aqoonsiga: Weelasha DMF waa in lagu calaamadeeyaa sumadaha cad iyo aqoonsiga, taasoo muujineysa taariikhda taariikhda, magaca, uruurinta, tirada iyo macluumaadka kale, si loo fududeeyo maaraynta iyo aqoonsiga.
