Maleic Anhydride: Chinhu Chinokosha Chemakemikari Anoshandiswa Pakugadzira Zvinhu Zvakasiyana-siyana
Minda mikuru yekushandisa
Muindasitiri yemakemikari, maleic anhydride chinhu chakakosha pakugadzira maresini epolyester asina kuzara (UPR). Maresini aya ane hunhu hwakanaka hwemakanika, anodzivirira makemikari, uye anodzivirira mamiriro ekunze uye anoshandiswa zvakanyanya mukugadzira mapurasitiki egirazi akasimbiswa nefiber (GFRP), akadai sezvikepe, zvikamu zvemotokari, uye mashizha emhepo. Pamusoro pezvo, maleic anhydride inogona kushandiswa kugadzira maresini ealkyd, ane kupenya kwakanaka uye anogara kwenguva refu uye anoshandiswa zvakanyanya mumaindasitiri ekupenda neingi.
Muindasitiri yepurasitiki, maleic anhydride inoshandiswa kugadzira mapurasitiki akagadziriswa maleic anhydride. Nekusanganisa mamonomers akasiyana, maleic anhydride inogona kuvandudza hunhu hwemapurasitiki, zvakaita sekuwedzera kusimba kwekupisa uye simba remakanika. Semuenzaniso, maleic anhydride yakasanganiswa nepolystyrene, yakasanganiswa nestyrene, ine hunhu hwakanaka hwekupisa uye hunhu hwemakanika uye inoshandiswa zvakanyanya mumaindasitiri emagetsi nemotokari.
Muindasitiri yerabha, maleic anhydride inoshandiswa kugadzira zvinowedzerwa zverabha. Inogona kuita serabha kugadzira zvivakwa zvakabatana, zvichiwedzera kuramba kupisa uye kuramba kupfeka kwerabha. Maleic anhydride inoshandiswawo kugadzira zvinokuvadza rabha uye zvinorwisa kukwegura, zvichiwedzera hupenyu hwezvigadzirwa zverabha.
Mumaindasitiri ekunhuhwirira nemishonga, maleic anhydride inoshandiswa sechikamu chepakati mukugadzirwa kwezvinonhuwira. Inogona kushandiswa kugadzira mhando dzakasiyana dzezvinonhuwira, dzakadai sediethyl maleate, iyo inoshandiswa zvakanyanya muzvinonhuwira uye zvizoro. Pamusoro pezvo, maleic anhydride inogona kushandiswa kugadzira zvimwe zvinhu zvemishonga, zvakaita sezvinobva mu maleic anhydride, zvekugadzira mishonga inorwisa mabhakitiriya nemishonga yemwoyo.
Mukurapa nemvura, maleic anhydride inoshandiswa kugadzira mishonga yekurapa mvura. Inogona kuita pamwe chete necalcium nemagnesium ions mumvura kuti igadzire mvura isinganyungudike, nokudaro ichideredza kuomarara kwemvura. Maleic anhydride inogonawo kushandiswa kugadzira mishonga inodzivirira ngura uye mishonga inodzivirira scale kudzivirira ngura uye kukura kwemvura.
Pasinei nekushandiswa kwayo kwakasiyana-siyana, maleic anhydride ine acid uye inoparadza, uye kushandiswa kwayo nekuchengetwa kwayo kunoda matanho akasimba ekuchengetedza. Maleic anhydride inonwisa hunyoro nyore nyore munzvimbo dzine hunyoro, saka inofanira kuchengetwa mumudziyo wakavharwa. Pamusoro pezvo, mhinduro dzemaleic anhydride dzinoparadza zvishoma, uye michina yakakodzera yekudzivirira inofanira kupfekwa panguva yekushandisa kudzivirira kusangana neganda nemaziso. Mukugadzirwa kwemaindasitiri, kushandiswa kwemaleic anhydride kunowanzoitika mumasisitimu akavharwa kuderedza kukanganisa kwezvakatipoteredza.

Muchidimbu
Muchidimbu, maleic anhydride, sechigadzirwa chakakosha chemakemikari eorganic, inoita basa guru mumaindasitiri akasiyana-siyana. Haingobatsiri chete pakushanda uye kunaka kwechigadzirwa asiwo inotsigira kukura kwemaindasitiri emazuva ano. Nekufambira mberi kwetekinoroji, mikana yekushandisa maleic anhydride ichave yakakura.
