I-anhydride ye-Maleic ineempawu zomgangatho ozinzile kunye nokusebenza okugqwesileyo kwimveliso ye-resin.Idlala indima ebalulekileyo ekudibaneni kweentlaka ezahlukeneyo ezifana neereyisi zepolyester ezingaxutywanga, i-alkyd resins, kunye ne-phenolic resins elungisiweyo.Ukuphinda kusebenze okugqwesileyo kwe-Maleic anhydride kunye nokuhambelana neentlobo ezahlukeneyo zeepolymers zongeza iipropathi zomatshini kunye ne-thermal ye-resin, iyenze ilungele uluhlu olubanzi lwezicelo.

Enye yeempawu eziphambili ze-maleic anhydride kukunyibilika kwayo emanzini, okunokwenza i-asidi ye-maleic xa inyibilikiswa emanzini.Olu phawu lwenza kube lula ukuphatha kunye nokudibanisa kwiinkqubo ezisekelwe emanzini, ukwandisa ngokuqhubekayo ukusetyenziswa kwayo ekuveliseni i-resin esekelwe emanzini.Ukongezelela, i-anhydride ye-maleic ibonakala njengeekristale ezimhlophe kunye nobuninzi be-1.484 g / cm3, inika iimpawu ezibonakalayo zokucoceka kunye nomgangatho.
Ukuqinisekisa ukuphathwa ngokukhuselekileyo kwe-maleic anhydride kubaluleke kakhulu.Kunconywa ukuba ulandele izikhokelo zokhuseleko ezibandakanya i-S22 (Musa ukuphefumla uthuli), i-S26 (Xa udibana namehlo, hlambulula ngokukhawuleza), S36/37/39 (Nxiba iimpahla ezifanelekileyo zokukhusela, iiglavu kunye nokukhuselwa kwamehlo / ubuso) kunye ne-S45 ( Kwimeko yengozi okanye ukuphazamiseka ngokomzimba, funa unyango ngokukhawuleza).Isimboli yengozi engu-C ibonisa ukuba yingozi enokubakho kwimpilo kwaye kufuneka kujongwane nayo ngokufanelekileyo.Iingxelo zeengozi ziquka i-R22 (iyingozi xa iginyiwe), i-R34 (ibangela ukutshisa) kunye ne-R42/43 (inokubangela uvakalelo ngokuphefumla nokudibana nolusu).
I-anhydride ye-Maleic inomgangatho ozinzile kwaye isetyenziswa ngokubanzi kwimveliso ye-resin, kwaye iyikhompawundi eyimfuneko kwishishini lemichiza.Ibonelela ngeenzuzo ezibalulekileyo ezifana neempawu eziphuculweyo ze-resin kunye nokuvumela ukubunjwa okusekelwe emanzini.Ukuguquguquka kwayo kunye nokusebenza kwakhona kwenza ukuba kube yinto efanelekileyo kwiinkqubo ezahlukeneyo zemizi-mveliso kunye nezorhwebo, okwenza ukuba kudalwe umgangatho ophezulu kunye nemveliso ehlala ixesha elide.
Isishwankathelo, i-anhydride ye-maleic, eyaziwa ngokuba yi-MA, yinto esetyenziswa ngokubanzi kwimveliso ye-resin.I-anhydride ye-Maleic, kunye nomgangatho wayo ozinzile, ukunyibilika kwamanzi, kunye nokuhambelana okugqwesileyo kunye ne-polymers, iphucula ukusebenza kwe-resin kwaye iyenze ifaneleke kwizicelo ezahlukeneyo.Nangona kunjalo, ngenxa yeengozi zezempilo ezinokuthi zibe kho ze-anhydride ye-maleic, ukuphatha i-anhydride ye-maleic kufuna ukuthotyelwa okungqongqo kwizikhokelo zokhuseleko.Lilonke, i-anhydride ye-maleic idlala indima ebalulekileyo kwishishini lemichiza kwaye ibalulekile ekwenzeni ii-resin ezisebenza kakhulu.
