Maleic Anhydride: Piny ma pire tek ma nyayu dongo i kabedo matung tung
Kabedo madongo mi tic
I tic mi kemikol, maleic anhydride ubedo piny ma pire tek pi yubu unsaturated polyester resins (UPR). Resins eni gitiye ku diru maber mi tic, tek pa kemikol, man tek pa koth man jutiyu kudu lee iyubu glass fiber-reinforced plastics (GFRP), calu yei, jamb mutukari, man wind turbine blades. Mi medo, maleic anhydride jucopo tiyo kudu pi yubu alkyd resins, ma gitiye ku ler maber man ma rii pi kare malac man jutiyo kudu lee i tic mi ketho rangi man rangi.
I tic mi plastik, maleic anhydride jutiyu kudu pi yubu plastik ma juloko ku maleic anhydride. Ku copolymerizing ku monomers matung tung, maleic anhydride copo medo ber pa plastik, calu medo kero pa lyethu man tego pa cuma. Ku lapor, maleic anhydride grafted polystyrene, copolymerized ku styrene, utiye ku kero maber mi juku lyethu man tic pa cuma man jutiyo kudu lee i tic mi cuma man mutukari.
I tic mi rubber, maleic anhydride jutiyu kudu pi yubu rubber additives. Ecopu timo tic ku rubber mi yubu piny ma rwate, ma medu kero pa rubber ikum lyethu man rwinyo pa rubber. Maleic anhydride de jutiyu kudu pi yubu piny ma nyayu lyethu pa rubber man piny ma jwigo dongo, ma medo kwo pa piny ma juyubu ku rubber.
I tic mi yiku nguce man yath, maleic anhydride jutiyu kudu calu piny ma jutiyo kudu pi yubu piny ma kwo. Ecopu bedu ni tiyo kudu pi yubu piny matung tung ma nyayu nguce, calu diethyl maleate, ma jutiyo kudu lee i wil man piny mi deyo. Mi medo, maleic anhydride jucopo tiyo kudu pi yubu yath moko, calu ve piny ma wok kud i maleic anhydride, pi yubu yath ma jwigo two man yath mi remo.
I tic mi yiku pii, maleic anhydride jutiyu kudu pi yubu piny ma yiku pii. Ecopu timo tic ku calcium man magnesium ions i pii mi yubu piny ma nyai ungo, ma dwoko piny tek pa pii. Maleic anhydride jucopo tiyo kudu pi yubu piny ma juku lyethu man piny ma juku lyethu pi jwigo lyethu man lyethu i pii.
Kadi bende tic kude utiye madwong, maleic anhydride utiye ku acid man nyai, man tic kude man gwoko pare mito gwok ma tek. Maleic anhydride mako pii yot yot in kabedu ma ngic, ci umitu jukethe i ajeni ma cego. Mi medo, jamb tic pa maleic anhydride utiye piny ma nyai, man jam gwoko kum maber umitu juketh ikare ma jutiyo kudu pi gwoko adila man wang. I tic mi yubu piny, tic ku maleic anhydride pol kare timere i kabedo ma cego pi jwigu peko mi kabedu.

I thum pa lembe
I ayi ma kicoko, maleic anhydride, calu piny ma pire tek ma jutiyo kudu pi kwo, timo tic ma pire tek i tic matung tung. Ekonyo ngo kende kende tic pa piny man ber pa piny ento ekonyo bende dongo pa tic mi kare eni. Ku dongo dongo mi ryeko, yore mi tic ku maleic anhydride bibedo malac.
