Ziyini izakhiwo zomzimba nezamakhemikhali ze-manhydride yama-maleic?

Izakhiwo zomzimba nezamakhemikhali ze-Maleic Anhydride: Emazingeni okushisa asekamelweni, ibonakala njenge-granules emhlophe, izinaliti, ama-flakes, izinduku, amaqhubu noma amabhlogo, ngokucasuka okukhulu. Ubuningi obuhlobene: 1.48; Iphuzu lokuncibilika: 52.8°C; Iphuzu lokubila: 202.2°C. I-Maleic Anhydrid ingaphinde ibe sezingeni lokushisa eliphansi (60-80°C). Iyancibilika ku-ethanol, i-ether kanye ne-acetone; isabela namanzi ukuze yakhe i-maleic acid. Iyavutha, futhi umusi wayo kanye nothuli kungakha izingxube eziqhumayo uma kuhlanganiswa nomoya.
Izinga Eliphezulu Lempahla (GB-3676-92)
Ukubukeka: I-white flake, i-granular
Ubumsulwa be-Maleic Anhydrid ≥99.5%
Iphuzu lokwakheka kwekristalu ≥52.4°C
Umbala oncibilikayo ≤25Pt-Co
Okuqukethwe komlotha ≤0.005%
Okuqukethwe kwensimbi ≤5ppm

Kungani ukhetha i-Maleic Anhydride? Iwumgogodla wama-resin e-polyester angagcwele aphezulu, futhi ivula amakhemikhali ahlukahlukene angaphansi (i-BDO, i-THF, njll.). Sithumelele umyalezo manje ukuze uhlole izixazululo ze-MA ezenzelwe ibhizinisi lakho!
