Li-resin tsa Maiketsetso
Anhydride ea Maleic e arabela le polyols (e lateloa ke ho kopanya ka cross-linking le styrene) ho etsa li-resin tsa polyester tse sa tlalang (UPR), e leng resin ea thermosetting. UPR e arotsoe ka li-plastiki tse matlafalitsoeng ka faeba (FRP, tse tsejoang haholo e le polasetiki e matlafalitsoeng ka fiberglass) le li-plastiki tse sa matlafalitsoeng.
FRP e sebediswa kahong (mohlala, masela a kobehileng, matlo a seng a sebedisitsweng pele, matamo a ho sesa, matloana a ho hlapela, ditanka tsa metsi a ditshila), tlhahiso (mohlala, kantle ho sekepe/koloi, mekhabiso ya kahare, dibate, mamati/difensetere, diboto tsa motlakase tse sireletsang), boenjiniere ba dikhemikhale (mohlala, diphaephe, ditanka tsa polokelo, disebediswa tsa tikoloho), le thepa ya bareki (mohlala, dithupa tsa ho tshwasa ditlhapi, di-racket, diboto tsa lehlwa, di-club tsa kolofo, dihelmete tsa polokeho).
UPR e sa tiisetsoang e sebelisoa konkreiteng ea polyester, li-binder, liphahlo tsa bokaholimo (lipiano, thepa ea ka tlung), likonopo le 'mabole/onyx ea maiketsetso.

Anhydride ea rona ea maleic e na le maemo a litšila a tlase haholo le botsitso bo ikhethang ba mocheso—e phethahetse bakeng sa ho ntlafatsa ts'ebetso ea li-polyester le lipente tsa hau tse sa koaheloang. Tobetsa ho shebana le litharollo tsa phepelo tse etselitsoeng uena hona joale!
