Kugwiritsa Ntchito Maleic Anhydride

Maleic anhydride ndi chinthu chofunikira kwambiri chomwe chimagwiritsidwa ntchito m'mafakitale osiyanasiyana. Ntchito zake zazikulu ndi izi:

1. Kupanga Zipangizo za Polima

Ma Resins a Polyester Osakhuta (UPR): Uwu ndiye malo ogwiritsidwa ntchito kwambiri a maleic anhydride. MA imagwira ntchito ndi ma diol (monga ethylene glycol, propylene glycol) kuti ipange ma resins a polyester osakhuta. Ma resins awa amagwiritsidwa ntchito kwambiri popanga mapulasitiki opangidwa ndi fiberglass-reinforced (FRP), omwe amagwiritsidwa ntchito m'maboti, zida zamagalimoto, zida zamakemikolo, ndi zipangizo zomangira chifukwa cha mphamvu zawo zambiri, kukana dzimbiri, komanso kupepuka.

Ma Resin a Alkyd: Maleic anhydride amagwiritsidwa ntchito popanga ma resin a alkyd, omwe ndi ofunika kwambiri mu utoto wokongoletsera, zokutira zamafakitale, ndi ma varnish. Ma resin a Alkyd amathandiza kuti zokutirazo zikhale zolimba, zonyezimira, komanso zolimba.

Ma Polima Ena: Akhoza kupangidwa ndi ma monomers monga styrene, vinyl acetate, ndi acrylic esters kuti apange ma copolymers. Ma copolymers amenewa amagwiritsidwa ntchito mu zomatira, zomangira nsalu, ndi zosinthira pulasitiki kuti ziwonjezere magwiridwe antchito azinthu (monga, kukana kutentha, kusinthasintha).

2. Mankhwala Osakaniza Mankhwala

Kupanga Ma asidi Achilengedwe: Cis-Butenedioic Anhydride imadutsa mu hydrolysis kuti ipange maleic acid, ndipo hydrogenation yowonjezereka imatha kupanga succinic acid kapena tetrahydrophthalic anhydride. Zogulitsazi ndizofunikira kwambiri popanga mankhwala, mankhwala ophera tizilombo, ndi ma surfactants.

Kupanga Mankhwala Ophera Tizilombo: Maleic Anhydride Acid ndi chinthu chopangira mankhwala ena ophera tizilombo, monga mankhwala ophera tizilombo (monga mankhwala ophera tizilombo a glyphosate) ndi mankhwala ophera tizilombo, zomwe zimathandiza kuchepetsa tizilombo pa ulimi.

Mankhwala Osakaniza Mankhwala: Maleic Acid Anhydride imagwiritsidwa ntchito popanga zinthu zina zopangira mankhwala, monga mankhwala oletsa kutupa ndi mavitamini, zomwe zimagwira ntchito yofunika kwambiri mumakampani opanga mankhwala.

3. Makampani Opanga Mapepala ndi Nsalu

Chothandizira Kukula kwa Mapepala: Maleic anhydride copolymers amagwiritsidwa ntchito ngati zolimbikitsira kukula kwa mapepala. Amatha kupititsa patsogolo kukana madzi ndi kusindikizidwa kwa mapepala, zomwe zimapangitsa kuti akhale oyenera kupakidwa mapepala, mapepala opangidwa ndi anthu, ndi mitundu ina ya mapepala.

Zothandizira pa nsalu: 2 5-Furandine imagwiritsidwa ntchito popanga zinthu zomalizitsa nsalu, monga zinthu zoteteza ku makwinya ndi kufooka. Zinthu zimenezi zimatha kupangitsa kuti nsalu zisavunde komanso kulimba, makamaka nsalu za thonje ndi polyester.

4. Makampani Ogulitsa Mafuta ndi Gasi

Choletsa Kutupa: Maleic anhydride derivatives (monga maleic anhydride-vinylpyrrolidone copolymers) amagwiritsidwa ntchito ngati zoletsa dzimbiri mu mafuta oyeretsera madzi ndi mapaipi amafuta ndi gasi. Amatha kupanga filimu yoteteza pamwamba pa chitsulo, kuchepetsa dzimbiri lomwe limayambitsidwa ndi madzi ndi zinthu zowononga.

Choletsa Kukula: Cis-Butenedioic Anhydrides Maleic Anhydride imagwiritsidwanso ntchito pokonza zoletsa kukula, zomwe zimaletsa kupangika kwa kukula (monga calcium carbonate, calcium sulfate) m'zida zamafuta ndi mapaipi, zomwe zimaonetsetsa kuti kupanga kukuyenda bwino.

5. Ntchito Zina

Zowonjezera pa Chakudya: Zina mwa zinthu zomwe zimapangidwa ndi maleic anhydride (monga succinic acid, yomwe imapangidwa kuchokera ku maleic anhydride) zimagwiritsidwa ntchito ngati zowonjezera pazakudya, monga acidulants ndi zokometsera, mumakampani azakudya.

Zowonjezera Mafuta: Maleic Anhydride Flakes amagwiritsidwa ntchito popanga zowonjezera mafuta, monga zothira mafuta ndi ma antioxidants, zomwe zingathandize kuti mafuta odzola azigwira ntchito bwino komanso azikhala ndi moyo wautali.
