Maleic anhydride ine hunhu hwemhando yakagadzikana uye kuita kwakanakisa mukugadzira resin. Inoita basa rakakosha mukuumbwa kweakasiyana siyana senge unsaturated polyester resins, alkyd resins, uye modified phenolic resins. Maleic anhydride's yakanakisa reactivity uye kuenderana nemhando dzakasiyana dzemapolymers inosimudzira iyo mechanic uye yekupisa zvimiro zveresin, zvichiita kuti ive yakakodzera kune dzakasiyana siyana dzekushandisa.

Imwe yemhando huru ye maleic anhydride kunyungudika kwemvura, iyo inogona kugadzira maleic acid kana yanyungudika mumvura. Ichi chimiro chinoita kuti zvive nyore kubata uye kubatanidzwa mumvura-based systems, kuwedzera kuwedzera kushandiswa kwayo mukugadzirwa kwemvura-based resins. Pamusoro pezvo, maleic anhydride inoratidzika semakristasi machena ane density ye1.484 g/cm3, ichipa zviratidzo zvekuona kuchena kwayo uye kunaka.
Kuve nechokwadi chekubata zvakachengeteka kwemaleic anhydride kwakakosha zvakanyanya. Inokurudzirwa kutevera mitemo yekuchengetedza inosanganisira S22 (Usafema guruva), S26 (Kana ukasangana nemaziso, sukurudza pakarepo), S36/37/39 (Pfeka zvipfeko zvakakodzera zvekudzivirira, magurovhosi uye ziso / chiso chekudzivirira) uye S45 ( Muchiitiko chetsaona kana kusagadzikana mumuviri, tsvaga kurapwa nekukurumidza). Mucherechedzo wengozi C unoratidza kuti ingangove njodzi kuhutano uye inofanirwa kugadziriswa nenzira kwayo. Mashoko engozi anosanganisira R22 (inokuvadza kana ikamedzwa), R34 (inokonzera kupisa) uye R42/43 (inogona kukonzera kunzwisiswa nekufemerwa uye kubata ganda).
Maleic anhydride ine yakagadzikana mhando uye inoshandiswa zvakanyanya mukugadzira resin, uye chinhu chakakosha muindasitiri yemakemikari. Iyo inopa zvakakosha zvakakosha senge yakagadziridzwa resin zvivakwa uye inogonesa mvura-yakavakirwa maumbirwo. Kuita kwayo kwakasiyana-siyana uye kuita zvekare kunoita kuti ive yakanaka kune dzakasiyana siyana dzemaindasitiri uye zvekutengesa, zvichiita kuti kugadzirwa kwemhando yepamusoro uye zvigadzirwa zvinogara kwenguva refu.
Muchidimbu, maleic anhydride, inozivikanwawo seMA, inoshandiswa zvakanyanya organic musanganiswa mukugadzira resin. Maleic anhydride, nemhando yayo yakagadzikana, kunyungudika kwemvura, uye kuenderana kwakanyanya nemapolymers, inosimudzira mashandiro eresin uye inoita kuti ive yakakodzera kune akasiyana maapplication. Nekudaro, nekuda kwenjodzi dzehutano dzinogona kuitika dze maleic anhydride, kubata maleic anhydride kunoda kuteedzera kwakasimba kumitemo yekuchengetedza. Pakazere, maleic anhydride inoita basa rakakosha muindasitiri yemakemikari uye yakakosha pakugadzirwa kwepamusoro-kuita resin.
