Maleic anhydride, oo sidoo kale loo yaqaano fuuq-baxa malic anhydride, waxay leedahay ur kulul oo xoog leh heerkulka qolka, muuqaalku waa crystals cad, caanaha kimikalka waa C4H2O3.Solubility of maleic anhydride: ku milma inta badan dareerayaasha organic sida biyaha, acetone, benzene, chloroform;miisaanka kelli: 98.057;CAS: 108-31-6;EINECS nambarka: 203-571-6.
Isticmaalka maleic anhydride
Maleic anhydride waxaa inta badan loo isticmaalaa sida walxo ceeriin ah oo loogu talagalay soo saarista xabagta polyester-ka aan qoyanayn, resin alkyd, malathion sunta cayayaanka, waxtarka sare iyo sunta yar-yar ee 4049, iodine amine oo muddo dheer shaqaynaysa, iwm.
Waxa kale oo ay komonomer u tahay dahaarka, rosinka lab, anhydride polymaleic, iyo copolymer anhydride-styrene lab ah;
Sidoo kale waa walxo kiimiko ah oo ceeriin ah oo loogu talagalay soo saarista kaabayaal khad, kaaliyayaal waraaqo-sameeye ah, balaastiigiyeyaasha, tartaric acid, fumaric acid, tetrahydrofuran, iwm.
Baakadaha maleic anhydride, kaydinta iyo gaadiidka
Taxadarrada Gaadiidka:Baakadu waa inay noqotaa mid dhamaystiran, raristaduna waa inay ahaataa mid sugan wakhtiga dhoofaysa.Inta lagu jiro gaadiidka, hubi in weelku aanu daadan, dumin, dhicin ama aanu dhaawacmin.Waxaa si adag loo mamnuucay in lagu qaso oo lagu raro oksaydhiyeyaasha, dhimista walxaha, acids, kiimikooyinka la cuni karo, iwm. Inta lagu jiro gaadiidka, waa in laga ilaaliyo soo-gaadhista iftiinka qorraxda, roobka, iyo heerkulka sare.
Taxaddar Kaydinta:Ku kaydi bakhaar qabow, qalalan, oo hawo wanaagsan leh.Ka fogow dabka iyo ilaha kulaylka.Weelka si adag u xidh.Waa in si gooni ah loo kaydiyaa oksaydhiyeyaasha, hoos u dhigista wakiilada, acids, iyo kiimikooyinka la cuni karo, mana aha in la isku daro.Lagu qalabeeyay noocyada ku habboon iyo tirada qalabka dabka.Goobaha kaydinta waa in la siiyaa agab ku haboon oo ay ku jiraan daadanta.
Ka taxaddarrada baakadaha:bacaha balaastikada ah ama bacaha warqadaha kraft-ka ee laba-lakab leh oo leh furitaan buuxa ama durbaanno bir ah oo dhexdhexaad ah;bacaha balaastikada ah ama bacaha laba lakab ee kraft bacaha ka baxsan durbaannada fiberboard-ka, durbaannada alwaaxyada, iyo durbaannada kartoonada;bacaha balaastikada ah ee ka baxsan durbaannada caagga ah (adag);durbaannada caagga ah (dareeraha).
