Ma resini aakupanga
Maleic anhydride ilaswaangana ama polyols (kutobelwa akuswaanganya a styrene) kuchita unsaturated polyester resins (UPR), thermosetting resin. UPR ilaandaanizyigwa muzibeela zyamapulasitiki aajisi nsinga (FRP, iizyibidwe kapati kuti mapulasitiki aajisi nsinga zyagilazi) alimwi amapulasitiki aatakwe nsinga.
FRP ilabelesyegwa mukuyaka (nkokuti, mapepa aajisi mabwe, maanda aapangidwe kale, madambwa, zimbuzi, matanki aameenda aasofweede), mukupanga zintu (nkokuti, anze lyabwaato/myootokala, zintu zyamukati, mabbodi aakusamba, milyango/mawindo, mabboodi aakukwabilila magesi), kupanga misamu (nkokuti, matanki aakubambila mapaipi, zibelesyo zyakubelesya alimwi azibelesyo zyakubelesya (nkokuti, nkoli zyakuzuba nswi, mabbaaji, mabboodi aachivwulamabwe, nkoli zyagolufu, zigogo zyakukwabilila).
UPR iitakwe nguzu ilabelesyegwa mu polyester concrete, zintu zyakujatila, zintu zyakuvwumba (piyano, zyamuŋanda), mabbatani, antoomwe amabbwe aapangidwe aa marble/onyx.

Maleic anhydride yesu ilaa busofwaazi buce kapati alimwi ilaa nguzu zyakupya kapati—zili kabotu kapati mukusumpula mulimo wama polyesters aako aatakwe busani alimwi azintu zyakuvwumba. Dina kuti ujane nzila zyakujana zintu zili kabotu lino!
