Ma Resin Opangidwa
Maleic anhydride imakumana ndi ma polyol (kutsatiridwa ndi cross-linking ndi styrene) kuti ipange ma unsaturated polyester resins (UPR), thermosetting resin. UPR imagawidwa m'mapulasitiki opangidwa ndi ulusi (FRP, omwe amadziwika kuti fiberglass-reinforced plastic) ndi mapulasitiki osapangidwanso.
FRP imagwiritsidwa ntchito pomanga (monga mapepala opangidwa kale, nyumba zokonzedwa kale, maiwe osambira, zimbudzi, matanki amadzi otayira), kupanga (monga, zokongoletsa zakunja za sitima/galimoto, zokongoletsera zamkati, mabafa, zitseko/mawindo, ma board amagetsi oteteza), uinjiniya wa mankhwala (monga mapaipi, matanki osungiramo zinthu, zida zachilengedwe), ndi zinthu zogwiritsidwa ntchito ndi anthu (monga ndodo zosodza, ma racket, ma snowboard, zibonga za gofu, zipewa zoteteza).
UPR yosalimbikitsidwa imagwiritsidwa ntchito mu konkriti ya polyester, zomangira, zokutira pamwamba (piyano, mipando), mabatani, ndi marble/onyx yopangidwa.

Anhydride yathu ya maleic ili ndi kuchuluka kochepa kwa kuipitsidwa komanso kukhazikika kwa kutentha kwabwino kwambiri—kwabwino kwambiri powonjezera magwiridwe antchito a ma polyester ndi zokutira zanu zosakhuta. Dinani kuti mupeze mayankho okonzedwa bwino tsopano!
