Luhlobo luni lwe-slfvent i-DMF?
I-DimyethylfoLlamilide (DMF) sisinyibilikisi esisetyenziswa ngokubanzi kwishishini lekhemikhali. Ukuqonda ukuba loluphi uhlobo lwe-DMF ye-SOSF kubalulekile ukuba ibaluleke kakhulu kwiingcali kwimveliso yemichiza, uphando lwelebhu kunye nemimandla enxulumene noko. Kweli nqaku, siya kuhlalutya iipropathi zeekhemikhali ze-DMF, ukusetyenziswa kwayo kunye nezicelo zayo kwimimandla eyahlukeneyo ukunceda abafundi ukuba bafumane ukuqonda okubaluleke kakhulu.
Chemistry ye-DMF
Luhlobo luni lwe-slfvent i-DMF? Okokuqala, kufuneka siqale kwipropathi yekhemikhali.dmf ifomula ye-moleula ye-moleula yi-c₃h₇no, kwaye ngokokwakhiwa yi-dimthyl ye-dimyeyl yefom. Yinto engenamibala, ebonakalayo, ihamba ngokulula i-fishy ye-odourt ye-odourt.a eyahlukileyo ye-DMF yindawo ephakamileyo ye-DMF iphezulu kakhulu, enomthamo wesidlo esiphakamileyo, owenza ukuba achithe zombini izinto eziphilayo. Ke ngoko, i-DMF idlala indima ebalulekileyo njengesinyibilikisi kwimichiza eyahlukeneyo yokuphendula.
Ukungaguquguquka kwe-DMF
Ukuqonda ukuba yeyiphi i-DMF injengesolwvent encedayo ukubona uluhlu lwayo olubanzi lokusetyenziswa kwiindawo ezahlukeneyo.dmf zisetyenziswa ikakhulu njenge-polymer ejijekileyo, i-sport proiness kunye nokucoca i-Solting. Umzekelo, ekuvelisweni kweentsinga kunye neeplasitiki, i-DMF yisolvent ebalaseleyo yePolyurethane ne-Polyvingl chlorinkl hlolor; Kumzi-mveliso wamachiza, kusetyenziswa ngokubanzi njengomntu ophakathi we-onnthesic, ngakumbi ukulungiselela izinto ezisebenzayo. Kwiilebhu zemichiza, i-DMF ihlala isetyenziselwa ukunyibilikisa iindima zepolar, ukunceda abaphandi ukuba benze imisebenzi yekhemikhali echanekileyo.
IINGXAKI ze-DMF kwizicelo ezikhethekileyo
Kwizicelo ezithile ezikhethekileyo, indima ye-DMF ivele kakhulu. Umzekelo, i-DMF isetyenziswe ngokubanzi kwi-electrochemists, apho kuhlala khona i-dislectrist yayo kakhulu kwenza isombo iqhelekileyo, kwaye sisinyibilikisi esibalulekileyo, ngakumbi kwiinkqubo zokucoca ezifuna ukuba izixhobo ze-elektroniki kunye nezixhobo zokuchaneka. Ukuqonda ukuba yeyiphi i-DMF i-Solf inokuthi incede ekukhetheni indlela efanelekileyo yokucoca kunye nokuphucula ukusebenza kakuhle komsebenzi.
Inkxalabo yokhuseleko kunye nendalo ye-DMF
Nangona i-DMF inoluhlu olubanzi lwezicelo, kodwa ukhuseleko lwayo noKhuseleko lweNdalo akufuneki lungahoywa. I-DMF inomgangatho othile wetyhefu, ukuvezwa kwexesha elide kunokubangela ukonakala kwesibindi, ukusetyenziswa kwenkqubo kufuneka kuthathe amanyathelo afanelekileyo okhuseleko, njengokunxiba iigloves, imaski, ukuqinisekisa ukuba imeko yokusebenza ingena umoya. Ukulahlwa kwenkunkuma ye-DMF ikwangumcimbi obalulekileyo, ulawulo olululo lwenkunkuma sisitshixo sokunciphisa ungcoliseko lwendalo.
Ukuqukumbela
I-DMF sisinyibilike kakhulu kwaye isetyenziswe ngokubanzi. Ukuqonda ukuba yeyiphi i-DMF i-Solf ingenakukwazi ukufumana iingcali zokukhetha ngcono kwaye isebenzise i-solvent, kodwa ikwaphucula ukhuseleko kunye nokusebenza ngokukuko. Ngophuhliso oluqhubekayo lwetekhnoloji yamachiza, ibango kunye nokusetyenziswa kwe-DMF kuya kukhula.
