Maleic Anhydride: K'hemik'hale ea Bohlokoa ea Lintho tse Tala tsa Organic e Khanyang Nts'etsopele ho pholletsa le Makala a 'Maloa
Masimo a Maholo a Kopo
Indastering ea lik'hemik'hale, anhydride ea maleic ke thepa ea bohlokoa bakeng sa ho hlahisa li-resin tsa polyester tse sa koaheloang (UPR). Li-resin tsena li na le thepa e ntle ea mechini, ho hanyetsa lik'hemik'hale, le ho hanyetsa boemo ba leholimo 'me li sebelisoa haholo tlhahisong ea polasetiki e matlafalitsoeng ka fiber ea khalase (GFRP), joalo ka likepe, likarolo tsa likoloi le mahare a turbine ea moea. Ho feta moo, anhydride ea maleic e ka sebelisoa ho kopanya li-resin tsa alkyd, tse nang le khanya e ntle le ho tšoarella hantle 'me li sebelisoa haholo indastering ea ho roala le ho kenya enke.
Indastering ea polasetiki, anhydride ea maleic e sebelisoa ho hlahisa polasetiki e fetotsoeng ke anhydride ea maleic. Ka ho kopanya le li-monomer tse fapaneng, anhydride ea maleic e ka ntlafatsa litšobotsi tsa polasetiki, joalo ka ho eketsa khanyetso ea mocheso le matla a mechini. Mohlala, polystyrene e kopantsoeng le anhydride ea maleic, e kopantsoeng le styrene, e na le khanyetso e ntle ea mocheso le litšobotsi tsa mechini 'me e sebelisoa haholo indastering ea lisebelisoa tsa elektroniki le tsa likoloi.
Indastering ea rabara, maleic anhydride e sebelisoa ho hlahisa lintho tse eketsang rabara. E ka arabela le rabara ho etsa meaho e hokahaneng, e eketsang ho hanyetsa mocheso le ho hanyetsa ho tsofala ha rabara. Maleic anhydride e boetse e sebelisoa ho hlahisa lintho tse thibelang rabara le lintho tse thibelang botsofali, e leng se eketsang bophelo ba tšebeletso ea lihlahisoa tsa rabara.
Liindastering tsa monko o monate le meriana, maleic anhydride e sebelisoa e le karolo e bohareng ea tlhahiso ea lintho tse phelang. E ka sebelisoa ho kopanya mefuta e fapaneng ea metsoako ea monko o monate, joalo ka diethyl maleate, e sebelisoang haholo libanong le litlolong. Ho feta moo, maleic anhydride e ka sebelisoa ho kopanya metsoako e itseng ea meriana, joalo ka li-derivatives tsa maleic anhydride, bakeng sa tlhahiso ea lithibela-mafu le meriana ea pelo le methapo.
Kalafong ea metsi, maleic anhydride e sebelisoa ho hlahisa metsoako ea kalafo ea metsi. E ka arabela le li-ion tsa calcium le magnesium ka metsing ho etsa marotholi a sa qhibiliheng, ka hona e fokotsa ho thatafala ha metsi. Maleic anhydride e ka boela ea sebelisoa ho hlahisa metsoako ea ho thibela ho bola le ho bola ha metsi ho thibela ho bola le ho bola ha metsi lits'ebetsong tsa metsi.
Ho sa tsotellehe mefuta e mengata ea ts'ebeliso ea eona, maleic anhydride e na le asiti ebile e senya, 'me ts'ebeliso le polokelo ea eona e hloka mehato e tiileng ea ts'ireletso. Maleic anhydride e monya mongobo habonolo libakeng tse mongobo, kahoo e hloka ho bolokoa ka setshelong se koetsoeng. Ho feta moo, litharollo tsa maleic anhydride li senya hanyane, 'me lisebelisoa tse loketseng tsa tšireletso li lokela ho aparoa nakong ea ts'ebeliso ho qoba ho kopana le letlalo le mahlo. Tlhahisong ea indasteri, ts'ebeliso ea maleic anhydride hangata e etsahala lits'ebetsong tse koetsoeng ho fokotsa tšusumetso ea tikoloho.

Ka kakaretso
Ka bokhutšoanyane, anhydride ea maleic, e le thepa ea bohlokoa ea lik'hemik'hale tse tala tsa tlhaho, e bapala karolo ea bohlokoa liindastering tse ngata. Ha e ntlafatse ts'ebetso ea sehlahisoa le boleng feela empa hape e tšehetsa nts'etsopele ea indasteri ea sejoale-joale. Ka tsoelo-pele e tsoelang pele ea theknoloji, menyetla ea ts'ebeliso ea anhydride ea maleic e tla ba kholo le ho feta.
