Tšebeliso ea Maleic Anhydride

Anhydride ea maleic ke thepa ea bohlokoa ea lik'hemik'hale tsa tlhaho e nang le mefuta e mengata ea lits'ebetso ho pholletsa le liindasteri tse ngata. Tšebeliso ea eona e ka sehloohong ke e latelang:

1. Tlhahiso ea Lisebelisoa tsa Polymer

Li-Resins tsa Polyester tse sa Tlatsoang (UPR): Ena ke sebaka se seholo ka ho fetisisa sa ts'ebeliso ea maleic anhydride. MA e arabela le diols (tse kang ethylene glycol, propylene glycol) ho etsa li-resins tsa polyester tse sa Tlatsoang. Li-resins tsena li sebelisoa haholo tlhahisong ea polasetiki e matlafalitsoeng ka fiberglass (FRP), e fumanang ts'ebeliso likepeng, likarolong tsa likoloi, lisebelisoa tsa lik'hemik'hale le thepa ea kaho ka lebaka la matla a tsona a phahameng, ho hanyetsa mafome le thepa e bobebe.

Li-resin tsa Alkyd: Anhydride ea maleic e sebelisoa ho etseng li-resin tsa alkyd, e leng likarolo tsa bohlokoa penteng ea mekhabiso, li-coat tsa indasteri le li-varnish. Li-resin tsa alkyd li ntlafatsa ho khomarela, ho benya le ho tšoarella ha li-coat.

Li-Polymer tse ling: E ​​ka kopanngoa ka li-monomer tse kang styrene, vinyl acetate, le li-ester tsa acrylic ho hlahisa li-copolymer. Li-copolymer tsena li sebelisoa ho likhomaretsi, li-auxiliaries tsa masela, le li-modifiers tsa polasetiki ho ntlafatsa ts'ebetso ea sehlahisoa (mohlala, ho hanyetsa mocheso, ho tenyetseha).

2. Lik'hemik'hale tse Mahareng

Tlhahiso ea Li-acid tsa Organic: Cis-Butenedioic Anhydride e feta hydrolysis ho etsa maleic acid, 'me hydrogenation e eketsehileng e ka hlahisa succinic acid kapa tetrahydrophthalic anhydride. Lihlahisoa tsena ke lintho tsa bohlokoa tse kopanyang meriana, chefo e bolaeang likokoanyana le li-surfactants.

Ho Kopanngoa ha Likokoana-hloko: Maleic Anhydride Acid ke thepa e tala bakeng sa ho hlahisa likokoanyana tse itseng tse bolaeang likokoanyana, joalo ka libolaya-mofuta (mohlala, li-glyphosate intermediates) le libolaya-mofuta, tse tlatsetsang taolong ea likokoanyana tlhahisong ea temo.

Meriana e Mahareng: Maleic Acid Anhydride e sebediswa ho kopanyeng thepa e meng e tala ya meriana, jwalo ka meriana e thibelang ho ruruha le divithamine, e bapala karolo ya bohlokwa indastering ya meriana.

3. Liindasteri tsa Pampiri le Masela

Sesebediswa sa ho lekanya boholo ba pampiri: Di-copolymer tsa anhydride tsa maleic di sebediswa e le disebediswa tsa ho lekanya boholo ba pampiri ka hare. Di ka ntlafatsa ho hanyetsa metsi le ho kganya ha pampiri, e leng se etsang hore e lokele ho sebediswa bakeng sa pampiri ya ho paka, pampiri ya setso le mefuta e meng ya pampiri.

Lisebelisoa tsa Lesela: 2 5-Furandine e sebelisetsoa ho hlahisa lintho tse felisang masela, tse kang lintho tse hanelang ho kobeha le tse hanelang ho honyela. Lintho tsena li ka ntlafatsa ho kobeha le ho tšoarella ha masela, haholo-holo bakeng sa masela a k'hothone le a polyester.

4. Indasteri ea Oli le Khase

Sethibela-mafu: Di-derivatives tsa anhydride tsa Maleic (mohlala, maleic anhydride-vinylpyrrolidone copolymers) di sebediswa e le dithibela-mafu tsa mafu tsa kalafo ya metsi a oli le diphaephe tsa oli le kgase. Di ka etsa filimi e sireletsang hodima bokahodimo ba tshepe, e fokotsang mafu a bakwang ke metsi le metswako e senyang.

Sethibela-makala: Cis-Butenedioic Anhydrides Maleic Anhydride e boetse e sebelisoa ho lokiseng lithibela-makala, tse thibelang ho thehoa ha sekala (joalo ka calcium carbonate, calcium sulfate) lisebelisoa tsa oli le liphaephe, ho netefatsa ts'ebetso e boreleli ea tlhahiso.

5. Likopo tse ling

Ditlatsetso tsa Lijo: Dintho tse itseng tse tswang ho maleic anhydride (mohlala, succinic acid, e hlahiswang ho tswa ho maleic anhydride) di sebediswa e le dintho tse eketsang dijo, tse kang di-acid le di-extender tsa tatso, indastering ya dijo.

Litlolo tse Ekelitsoeng: Maleic Anhydride Flakes e sebelisetsoa ho kopanya lintho tse eketsang mafura, tse kang li-dispersant le li-antioxidants, tse ka ntlafatsang ts'ebetso le bophelo ba ts'ebeletso ea oli e tlotsang.
