IMITERERE:
Anhydride ya Maleic (MAN) ni ikintu kigizwe n'ibinyabuzima gifite formula ya C4H203. Ni aside anhydride ya aside maleic kandi mu buryo bwayo bwiza ni ikintu kidafite ibara cyangwa umweru gifite impumuro y'akari. Anhydride ya Maleic ni molekile itangaje kuko ifite ubwoko bubiri bw'imikorere ya shimi ituma igira akamaro kadasanzwe mu gukora no gukoresha shimi.
Anhydride ya Maleic ni igikoresho cy’ibinyabutabire gifite imikorere myinshi kandi gikoreshwa mu nzego zitandukanye z’inganda z’ibinyabutabire. Ikoreshwa cyane cyane nk'ibiribwa mu gukora resins za polyester zidafite ubushyuhe (UPR).
Izi resins zikoreshwa haba mu bikoresho byometse ku kirahure ndetse no mu bikoresho bitarashyirwamo ingufu. Uburyo bwa UPR bukoreshwa burimo ibintu byinshi bitandukanye mu bwubatsi, mu mazi no mu nganda z'imodoka.

Imikoreshereze
Anhydride ya Maleic ni imvange ya heterocyclic ikoreshwa mu gukora resins za polyester zidafite ubushyuhe. Ifite izindi ngaruka nyinshi; ikoreshwa mu miti ikoreshwa mu byuma bivanze, imiti yica udukoko, imiti yica udukoko n'imiti irwanya udukoko.
Anhydride ya maleiki ikoreshwa mu gukora Diels-Alder syntheses (nk'umuti uvura indwara), mu gukora resins zo mu bwoko bwa alkyd, intermediates zo gusiga irangi, imiti, imiti ikoreshwa mu buhinzi (maleiki hydrazide, malathion), mu gukora copolymerization reactions.
Gupakira no Kohereza
25KG/igikapu cyangwa nk'uko umukiriya abikeneye.
Ni iy'ibicuruzwa rusange kandi ishobora gutangwa binyuze mu nyanja no mu kirere
Bika kandi ubibike
Igihe cyo kubika: Amezi 24 uhereye igihe byakorewe mu ipaki y’umwimerere idafunguye, bibitswe ahantu hakonje kandi humutse, kure y’izuba ryinshi, amazi.
Ububiko bufite umwuka uhagije, Butuma ibintu bishya bishyuha, butandukanyijwe n'ibikomoka kuri okiside, aside.
