Yuav ua li cas kom polycarbonate hluav taws resistant thiab ncaj?
Polycarbonate yog ib hom kev tsim cov yas nrog kev ua tiav zoo thiab siv dav. Nws muaj kev ncaj ncees siab heev, thiab lub teeb xa tawm tuaj yeem ncav cuag 89 feem pua. Nws tuaj yeem ua tau raws li ntau qhov xwm txheej nrog rau qhov yuav tsum tau ua ua ntej rau optics thiab ntau yam. Tsis tas li ntawd, nws ua rau qhov sib txawv ntawm qhov hluav taws kub, uas tuaj yeem tuaj txog ntawm V-2 hluav taws kub. Nws yog tus kheej smothering tsim yas.
Txawm li cas los xij, hauv qee qhov xwm txheej, nws yog ib qho tseem ceeb kom ua tiav V{{{0}} hluav taws kub 1.6 hli lossis txawm tias 0.8 hli, piv txwv li, xov tooj ntawm tes thiab lwm yam khoom siv hluav taws xob, PC films, PC daim hlau thiab sib txawv teb, thiab ntxiv mus kom raws li kev ncaj ncees ntawm lub PC, uas muaj cov kev sib tw tshwj xeeb. Txawm li cas los xij, kev siv hluav taws kub resistant tuaj yeem ua haujlwm ntawm qhov hluav taws kub resistant qib ntawm PC.
Txog tam sim no, cov hluav taws kub retardants siv rau PC tseem ceeb suav nrog phosphate, ntuj silicon thiab sulfonate. Phosphate hluav taws kub retardants (xws li BDP thiab RDP) yuav tsum tau suav nrog ib qho txiaj ntsig loj heev los cuam tshuam PC, uas yog inclined rau trickling. Kev npau taws rau dribbling cov kws tshaj lij yuav tsum tau ntxiv, uas yuav cuam tshuam rau kev ncaj ncees ntawm PC. Cov sulfonic corrosive ntsev thiab organosilicon hluav taws kub retardants tuaj yeem ua raws li kev ncaj ncees ntawm PC.
1, Sulfonate hluav taws resistant
Sulfonate hluav taws resistant muaj qhov chaw nrog soluble ntiaj teb hlau ntsev, uas muaj hluav taws kub resistant zoo rau cov khoom PC. Cov khoom siv feem ntau yog cov sodium 2,4, 5-trichlorobenzenesulfonate (STB), potassium phenylsulfonyl benzene sulfonate (KSS), thiab potassium perfluorobutylsulfonate (PPFBS). STB muaj cov tshuaj chlorine, uas feem ntau yog siv hauv cov txheej txheem PC tsis ncaj.
Hluav taws kub resistant system ntawm sulfonate hluav taws resistant:
Thaum qhov kub thiab txias, sulfonates tuaj yeem ua rau isomerization ntawm PC, tso cov pa roj carbon dioxide thiab dej thaum kub hnyiab, ua rau lub hnub nyoog ntawm phenols, ua rau lub hnub nyoog ntawm aliphatic thiab qab zib-smelling accumulates, ua kom cov pa roj carbon ntau ntawm cov khoom hauv PC, thiab ua rau lub hnub nyoog ntawm aliphatic thiab qab zib. cross-connecting ntawm polymer hais.
