I-China Factory Maleic Anhydride UN2215 MA 99.7% ye-Resin Production

I-anhydride ye-Maleic, eyaziwa ngokuba yi-MA, yikhompawundi eguquguqukayo yezinto eziphilayo esetyenziswa ngokubanzi kwimveliso ye-resin. Ihamba ngamagama ahlukeneyo, kubandakanywa i-malic anhydride ephelelwe ngamanzi kunye ne-maleic anhydride. I-formula yekhemikhali ye-anhydride ye-maleic yi-C4H2O3, ubunzima be-molecular yi-98.057, kunye ne-melting point range yi-51-56 ° C. I-UN yeeMpahla ezinobungozi ze-UN i-2215 ihlelwa njengento enobungozi, ngoko ke kubalulekile ukuphatha le nto ngononophelo.

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.

Ukunyibilika Sabele ngamanzi

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 nokwenza imiqulu esekwe 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 zempilo ezinokubakhona ze-maleic anhydride, ukuphatha i-anhydride ye-maleic kufuna ukuthotyelwa okungqongqo kwizikhokelo zokhuseleko. Lilonke, i-anhydride ye-maleic idlala indima ebalulekileyo kwishishini lemichiza kwaye ibalulekile ekwenzeni iireyini ezisebenza kakhulu.
