Kev siv ntawm Maleic Anhydride

Maleic anhydride yog ib yam khoom siv tseem ceeb hauv cov organic chemical uas muaj ntau yam kev siv thoob plaws ntau yam lag luam. Nws cov kev siv tseem ceeb yog raws li nram no:

1. Kev Tsim Khoom Siv Polymer

Cov Polyester Resins Unsaturated (UPR): Qhov no yog qhov chaw siv loj tshaj plaws ntawm maleic anhydride. MA reacts nrog diols (xws li ethylene glycol, propylene glycol) los tsim cov unsaturated polyester resins. Cov resins no yog siv dav hauv kev tsim cov fiberglass-reinforced plastics (FRP), uas pom cov ntawv thov hauv nkoj, cov khoom siv tsheb, cov khoom siv tshuaj lom neeg, thiab cov ntaub ntawv tsim kho vim lawv lub zog siab, tiv taus corrosion, thiab cov khoom sib dua.

Cov Alkyd Resins: Maleic anhydride yog siv rau hauv kev tsim cov alkyd resins, uas yog cov khoom tseem ceeb hauv cov xim pleev kom zoo nkauj, cov xim pleev rau kev lag luam, thiab cov varnishes. Cov alkyd resins txhim kho qhov kev sib txuas, kev ci ntsa iab, thiab kev ruaj khov ntawm cov xim pleev.

Lwm Cov Polymers: Nws tuaj yeem raug copolymerized nrog monomers xws li styrene, vinyl acetate, thiab acrylic esters los tsim cov copolymers. Cov copolymers no yog siv rau hauv cov nplaum, cov khoom siv textile, thiab cov yas hloov kho kom txhim kho cov khoom ua tau zoo (piv txwv li, tiv taus cua sov, yooj ywm).

2. Cov Tshuaj Nruab Nrab

Kev Tsim Cov Organic Acids: Cis-Butenedioic Anhydride dhau los ntawm hydrolysis los ua maleic acid, thiab hydrogenation ntxiv tuaj yeem tsim succinic acid lossis tetrahydrophthalic anhydride. Cov khoom no yog cov khoom siv tseem ceeb rau kev tsim cov tshuaj, tshuaj tua kab, thiab surfactants.

Kev Tsim Cov Tshuaj Tua Kab: Maleic Anhydride Acid yog cov khoom siv raw rau kev tsim cov tshuaj tua kab, xws li cov tshuaj tua kab (piv txwv li, glyphosate intermediates) thiab cov tshuaj tua kab, pab txhawb kev tswj kab tsuag hauv kev ua liaj ua teb.

Cov Tshuaj Nruab Nrab: Maleic Acid Anhydride yog siv rau hauv kev tsim cov khoom siv raw tshuaj, xws li cov tshuaj tiv thaiv kev o thiab cov vitamins, ua lub luag haujlwm tseem ceeb hauv kev lag luam tshuaj.

3. Kev Lag Luam Ntawv thiab Textile

Cov Tshuaj Ntsuas Qhov Loj ntawm Daim Ntawv: Cov tshuaj Maleic anhydride copolymers yog siv los ua cov tshuaj ntsuas qhov loj sab hauv rau daim ntawv. Lawv tuaj yeem txhim kho qhov tsis kam dej thiab kev luam tawm ntawm daim ntawv, ua rau nws tsim nyog rau cov ntawv ntim khoom, ntawv kab lis kev cai, thiab lwm hom ntawv.

Cov Khoom Pab Txhawb Nqa Ntaub Ntawv: 2 5-Furandine yog siv los tsim cov tshuaj ua tiav ntaub ntawv, xws li cov tshuaj tiv thaiv kev crease thiab cov tshuaj tiv thaiv shrink. Cov tshuaj no tuaj yeem txhim kho kev hnav thiab kev ua haujlwm ntev ntawm cov ntaub, tshwj xeeb tshaj yog rau cov ntaub paj rwb thiab polyester.

4. Kev Lag Luam Roj thiab Roj Av

Tshuaj Tiv Thaiv Kev Xeb: Cov tshuaj Maleic anhydride derivatives (piv txwv li, maleic anhydride-vinylpyrrolidone copolymers) yog siv los ua cov tshuaj tiv thaiv kev xeb hauv kev kho dej hauv cov chaw roj thiab cov kav dej roj thiab roj av. Lawv tuaj yeem tsim ib daim zaj duab xis tiv thaiv rau ntawm qhov chaw hlau, txo cov kev xeb los ntawm dej thiab cov xov xwm xeb.

Tshuaj Tiv Thaiv Kab Mob: Cis-Butenedioic Anhydrides Maleic Anhydride kuj tseem siv rau hauv kev npaj cov tshuaj tiv thaiv kab mob, uas tiv thaiv kev tsim cov kab mob (xws li calcium carbonate, calcium sulfate) hauv cov khoom siv roj thiab cov kav dej, kom ntseeg tau tias kev ua haujlwm zoo ntawm kev tsim khoom.

5. Lwm Cov Ntawv Thov

Cov Khoom Noj Ntxiv: Qee cov khoom siv maleic anhydride derivatives (piv txwv li, succinic acid, uas yog tsim los ntawm maleic anhydride) yog siv ua cov khoom noj ntxiv, xws li cov acidulants thiab cov khoom ua kom tsw qab, hauv kev lag luam khoom noj.

Cov Khoom Siv Ntxiv Rau Lubricant: Maleic Anhydride Flakes yog siv los ua cov khoom siv ntxiv rau lubricant, xws li cov dispersants thiab antioxidants, uas tuaj yeem txhim kho kev ua tau zoo thiab lub neej ua haujlwm ntawm cov roj lubricating.
