Mashandisirwo eMaleic Anhydride

Maleic anhydride chinhu chakakosha chemakemikari eorganic chine mashandisirwo akasiyana-siyana mumaindasitiri akasiyana-siyana. Mashandisirwo ayo makuru ndeaya anotevera:

1. Kugadzirwa kwezvinhu zvePolymer

MaResins ePolyester Asina Kuzara (UPR): Iyi ndiyo nzvimbo huru inoshandiswa neanhydride ye maleic. MA inoshanda nema diols (akadai se ethylene glycol, propylene glycol) kuti igadzire maresins e polyester asina kuzara. Maresins aya anoshandiswa zvakanyanya mukugadzira mapurasitiki e fiberglass-reinforced (FRP), ayo anoshandiswa muzvikepe, zvikamu zvemotokari, makemikari, uye zvinhu zvekuvaka nekuda kwesimba rawo guru, kuramba ngura, uye hunhu hwawo hwakareruka.

MaResins eAlkyd: Maleic anhydride inoshandiswa mukugadzirwa kwemaresins ealkyd, ayo ari zvinhu zvakakosha mupendi yekushongedza, machira eindasitiri, uye mavarnish. Maresins eAlkyd anovandudza kunamira, kupenya, uye kugara kwenguva refu kwemachira.

Mamwe maPolymer: Anogona kupolymerzwa nemamonomer akaita se styrene, vinyl acetate, uye acrylic esters kugadzira macopolymer. Macopolymer aya anoshandiswa muma glues, ma textile auxiliaries, uye ma plastic modifiers kuti awedzere kushanda kwechigadzirwa (semuenzaniso, kuramba kupisa, kuchinjika).

2. Zvinoshandiswa Pamakemikari

Kugadzirwa kweOrganic Acids: Cis-Butenedioic Anhydride inonyungudika kuita maleic acid, uye kuwedzera kwehydrogenation kunogona kugadzira succinic acid kana tetrahydrophthalic anhydride. Zvigadzirwa izvi zvakakosha pakugadzirwa kwemishonga, mishonga yezvipembenene, uye surfactants.

Kugadzirwa kweMishonga Yezvipembenene: Maleic Anhydride Acid chinhu chakakosha pakugadzira mimwe mishonga yezvipembenene, yakadai semishonga yekuuraya zvipembenene (semuenzaniso, mishonga yezvipembenene yeglyphosate) uye mishonga yezvipembenene, zvichibatsira mukuderedza zvipembenene mukurima.

Mishonga Inoshanda Pakati: Maleic Acid Anhydride inoshandiswa mukugadzirwa kwezvimwe zvinhu zvemishonga, zvakaita semishonga inodzivirira kuzvimba uye mavhitamini, zvichiita basa rakakosha muindasitiri yemishonga.

3. Maindasitiri ePepa neMachira

Chinoumba Saizi Yepepa: Maleic anhydride copolymers anoshandiswa sezvinhu zvinoumba saizi yepepa mukati. Anogona kuwedzera kusapinda kwemvura uye kudhindwa kwepepa, zvichiita kuti rikwanise kushandiswa pakurongedza mapepa, mapepa emhando dzakasiyana, nemamwe marudzi emapepa.

Zvishandiso Zvemachira: 2 5-Furandine inoshandiswa kugadzira zvinhu zvinopedzisa machira, zvakaita sezvinhu zvinodzivirira kukwenya uye zvinodzivirira kutetepa. Zvinhu izvi zvinogona kuwedzera kupfekwa uye kugara kwenguva refu kwemachira, kunyanya kumachira edonje nepolyester.

4. Indasitiri yeOiri neGasi

Inhibitor yeKuora: Maleic anhydride derivatives (semuenzaniso, maleic anhydride-vinylpyrrolidone copolymers) anoshandiswa senzira dzekudzivirira ngura mukuchenesa mvura yemumunda wemafuta uye mumapaipi emafuta negasi. Anogona kugadzira firimu rekudzivirira pamusoro pesimbi, zvichideredza ngura inokonzerwa nemvura uye nzira dzekudzivirira ngura.

Chinodzivirira Kukura: Cis-Butenedioic Anhydrides Maleic Anhydride inoshandiswawo mukugadzira mishonga inodzivirira kukwira kwemasero, iyo inodzivirira kuumbwa kwemasero (akadai secalcium carbonate, calcium sulfate) mumidziyo yemafuta nemapaipi, zvichiita kuti kugadzirwa kushande zvakanaka.

5. Mamwe Mashandisirwo

Zvinowedzerwa muChikafu: Zvimwe zvinogadzirwa neanhydride yemhando ye maleic (semuenzaniso, succinic acid, inogadzirwa kubva kuanhydride yemhando ye maleic) zvinoshandiswa sezvinowedzera chikafu, zvakaita seacidulants uye zvinosimudzira kunaka, muindasitiri yechikafu.

Zvinowedzerwa pamafuta: Maleic Anhydride Flakes inoshandiswa kugadzira zvinowedzera mafuta, zvakaita sema dispersants nema antioxidants, izvo zvinogona kuvandudza mashandiro uye hupenyu hwemafuta ekuzora.
