Polyphenylene sulfide (PPS), nrog rau cov pob txha symmetrical txhav, yog ib feem ntawm cov crystalline polymer uas muaj cov rov ua dua para-hloov benzene rings thiab sulfur atoms. PPS yog ib qho tshwj xeeb engineering yas uas muaj kev ua tau zoo thiab lub siab melting point txog 280 ℃, uas tuaj yeem hloov tau hlau. Cov khoom zoo heev ntawm PPS resin ua rau nws ua tau raws li cov ntaub ntawv xav tau ntawm cov khoom siv tsheb.
PPS muaj ntau yam kev siv hauv kev lag luam tsheb, thiab qhov kev thov rau PPS hauv kev tsim cov teb chaws xws li Is Nrias teb, Tuam Tshoj, thiab Nyij Pooj tau nce ntxiv kom tau raws li qhov yuav tsum tau ua rau lub teeb yuag thiab ruaj khov ntawm lub tsheb.
PPS resin muaj cov khoom zoo hauv qab no:
1. Inherent nplaim retardancy, UL94:V-0/5VA qib tsis ntxiv nplaim retardant;
2. Cov tshuaj tiv thaiv zoo heev, mus txog qib ntawm cov kuab tshuaj tsis muaj kev sib cais hauv qab 200 ℃, zoo ib yam li cov tshuaj tiv thaiv qib PTFE;
3. Zoo seem stability, tsawg molding shrinkage thiab linear expansion coefficient; vim tias qhov nqus dej tsawg, qhov kev ruaj ntseg zoo tshaj plaws kuj tuaj yeem khaws cia hauv qhov chaw siab-humidity thiab high-temperature.
4. Cov khoom siv zoo tshaj plaws, lub zog siab thiab rigidity siab, nws tuaj yeem tswj kev qaug zog thiab nkag mus rau hauv ntau qhov chaw;
5. Kev ua haujlwm kub zoo heev, UL ntsuas qhov ntsuas kub (RTI): 200-220 ℃, HDT (kub kub distortion)> 260 ℃.
PPS ntshiab yog tsis tshua muaj siv ib leeg vim nws brittleness. Cov ntawv thov PPS feem ntau nws hloov kho ntau yam, uas feem ntau yog hloov kho los ntawm kev ntxiv iav fiber ntau.Cov lus hauv qab no teev cov kev siv cuam tshuam ntawm PPS hloov kho resins hauv tsheb:
