Cov roj hmab ua los ntawm cov khoom siv hluavtaws
Maleic anhydride reacts nrog polyols (ua raws li cross-linking nrog styrene) los tsim cov unsaturated polyester resins (UPR), ib qho thermosetting resin. UPR yog muab faib ua cov yas fiber-reinforced (FRP, feem ntau hu ua fiberglass-reinforced plastic) thiab cov yas tsis-reinforced.
FRP siv rau hauv kev tsim kho (piv txwv li, cov ntawv corrugated, cov tsev prefabricated, pas dej ua ke, chav dej, cov thoob dej khib nyiab), kev tsim khoom (piv txwv li, nkoj / tsheb sab nraud, sab hauv trim, dab da dej, qhov rooj / qhov rai, cov laug cam hluav taws xob rwb thaiv tsev), kev tsim kho tshuaj lom neeg (piv txwv li, cov kav dej, cov thoob dej cia khoom, cov khoom siv ib puag ncig), thiab cov khoom siv rau cov neeg siv khoom (piv txwv li, cov pas nrig nuv ntses, cov rackets, snowboards, cov khoom siv golf, cov kaus mom kev nyab xeeb).
UPR uas tsis yog siv zog yog siv rau hauv cov pob zeb polyester, cov khoom khi, cov tshuaj pleev xim rau saum npoo (piano, rooj tog), cov nyees khawm, thiab cov pob zeb marble/onyx cuav.

Peb cov maleic anhydride muaj cov qib tsis huv uas tsis tshua muaj thiab muaj kev ruaj khov thermal zoo heev—zoo meej rau kev ua kom koj cov polyesters thiab cov txheej tsis muaj roj ntau ntxiv. Nyem kom sab laj rau cov kev daws teeb meem kev muab khoom tam sim no!
