Kodi ndi mtundu wanji wa DMF?
Dimethylfermamide (DMF) ndi zosungunulira zomwe zimagwiritsidwa ntchito kwambiri pamakampani amakampani. Kumvetsetsa mtundu wa DMF ndikofunikira kuti akatswiri mwa kupanga mankhwala, kafukufuku wa labotale komanso minda yofananira. Munkhaniyi, tikambirana mwatsatanetsatane mankhwala a DMF, kugwiritsa ntchito kwake komanso ntchito zake m'malo osiyanasiyana kuti athandize owerenga kuti amvetsetse izi.
Chemistry of DMF
Kodi ndi mtundu wanji wa DMF? Choyamba, tiyenera kuyamba kuchokera kuzomera zake za mankhwala. It is a colourless, transparent, easy-flowing liquid with a faint fishy odour.A distinctive feature of DMF is its very high polarity, with a dielectric constant as high as 36.7, and a high solvency capacity, which enables it to dissolve both polar and non-polar substances. Chifukwa chake, DMF amatenga gawo lofunikira monga zosungunulira m'mankhwala osiyanasiyana.
Kusiyanitsa kwa DMF
Kumvetsetsa Zomwe DMF kuli ngati zosungunulira kumathandizira kuzindikira pogwiritsa ntchito mitundu yosiyanasiyana. Mwachitsanzo, kupanga ulusi ndi pulasitiki, DMF ndi zosungunulira bwino kwa polyirethane ndi polyvinyl chloride; M'makampani opanga mankhwala, imagwiritsidwa ntchito kwambiri ngati njira yomwe imachitidwa ngati zinthu zachilengedwe, makamaka pokonzekera zinthu zomwe zimagwira. Mu mankhwala a mankhwala, DMF nthawi zambiri amagwiritsidwa ntchito kusungunula mitundu ya polar yosiyanasiyana, kuthandiza ofufuza kuti akwaniritse magwiridwe antchito.
Ubwino wa DMF mumapulogalamu apadera
Munjira zina zapadera, udindo wa DMF umakhala wotchuka kwambiri. Mwachitsanzo, DMF imagwiritsidwa ntchito kwambiri mu edctrochemist, komwe diectric yake nthawi zambiri imapangitsa kuti ikhale zoyeserera wamba, makamaka kuyeretsa kofunikira, makamaka pakuyeretsa zida zamagetsi ndi zida zolondola. Kumvetsetsa zomwe DMF ndi zosungunulira kungathandize posankha njira yoyenera yoyeretsera bwino ndikusintha luso.
Chitetezo ndi zovuta zachilengedwe za DMF
Ngakhale DMF ili ndi mapulogalamu angapo, koma kuteteza kwake ndi chilengedwe sikuyenera kunyalanyazidwa. DMF ili ndi poizoni wina wa poizoni, kuwonekera kwa nthawi yayitali kungawononge chiwindi, kugwiritsa ntchito njirayi kuyenera kuteteza magolovesi oyenera, monga akuvala magolovesi oteteza, masks, kuonetsetsa kuti malo ogwiritsira ntchito ali ndi mpweya wabwino. Kutaya zinyalala kwa DMF ndi nkhani yofunika, kasamalidwe ka zinyalala ndi njira yochepetsera kuwonongeka kwa chilengedwe.
Mapeto
DMF ndi wofunikira kwambiri komanso wogwiritsa ntchito kwambiri. Kumvetsetsa zomwe DMF ndi zosungunulira sikungathandize ongofuna kusankha bwino kusankha ndikugwiritsa ntchito zosungunulira, komanso kusintha chitetezo ndi kuchita bwino. Ndi chitukuko mosalekeza mwa ukadaulo wa mankhwala, kufunsa ndi kugwiritsa ntchito kwa DMF kumakulanso.
