Waa maxay isticmaalka anhydride-ka maleic?

Maleic anhydride (oo sidoo kale loo yaqaan cis-butenedioic anhydride) waa walax muhiim ah oo kiimiko dabiici ah, oo ka mid ah anhydrides-ka (ka dib phthalic anhydride iyo acetic anhydride). Waxaa inta badan loo isticmaalaa in lagu soo saaro polyester-yada aan dheregsanayn iyo resins-ka alkyd, waxaana sidoo kale laga helaa isticmaalka sunta cayayaanka, dahaarka, khad, waxyaabaha lagu daro saliidda, kiimikooyinka sameynta waraaqaha, wakiilada dhammaystirka dharka, iyo surfactants. Waxyaabaha laga soo saaro maleic anhydride waxaa ka mid ah 1,4-butanediol, γ-butyrolactone, tetrahydrofuran, maleic acid, fumaric acid, iyo tetrahydrophthalic anhydride - dhammaantood waa kiimikooyin muhiim ah oo dabiici ah iyo kuwo fiican.

Maxaad u dooranaysaa Maleic Anhydride? Waa laf-dhabarta resins-ka polyester-ka ee heerka sare ah ee aan buuxin, iyo sidoo kale waxay furaysaa kiimikooyin kala duwan oo hoos yimaada (BDO, THF, iwm.). Noo soo dir fariin hadda si aad u sahamiso xalal MA ah oo loogu talagalay ganacsigaaga!
