Polystyrene (PS) Txhaj Moulding Txheej txheem
Jan 03, 2024| Cov ntawv thov: cov khoom ntim, cov khoom siv hauv tsev (tableware, tais, thiab lwm yam), hluav taws xob (pob tshab ntim, lub teeb diffusers, insulating films, thiab lwm yam).
Chemical thiab Physical Properties: Feem ntau cov lag luam PSs yog pob tshab, amorphous cov ntaub ntawv. PS muaj zoo geometric stability, thermal stability, optical kis tau tus mob zog, hluav taws xob rwb thaiv tsev zog thiab ib tug me ntsis nyiam nqus noo noo. Nws yog resistant rau dej thiab dilute inorganic acids, tab sis yuav corroded los ntawm muaj zog oxidizing acids xws li concentrated sulfuric acid, thiab tuaj yeem o thiab deform hauv qee cov organic solvents. Ib txwm shrinkage yog nyob nruab nrab ntawm {{0}}.4 ~ 0.7%.
Txhaj pwm txheej txheem txheej txheem:
- Kev ziab: Tshwj tsis yog khaws cia tsis raug, feem ntau tsis tas yuav ziab. Yog tias yuav tsum tau ziab, qhov kev pom zoo kom qhuav yog 80 degree thiab 2 mus rau 3 teev.
- Melting kub: 180 ~ 280 degree. Rau cov khoom siv hluav taws xob hluav taws xob sab saud yog 250 degree.
- Pwm kub: 40 ~ 50C.
- Txhaj siab: 200 ~ 600bar.
- Kev txhaj tshuaj nrawm: Nws raug nquahu kom siv qhov kev txhaj tshuaj nrawm.
- Khiav thiab rooj vag: Txhua hom rooj vag tuaj yeem siv tau.
Polystyrene (PS) tuaj yeem ua rau ntau yam khoom siv ntau hom kev ua haujlwm molding, suav nrog kev txhaj tshuaj molding, extrusion molding, blister molding thiab foam molding. PS tuaj yeem ua tiav ntawm cov extruders zoo tib yam. Lub extrusion molding ntawm films, nplooj ntawv thiab profiles yog feem ntau siv txoj kev rau PS ua thiab molding. Cov khoom siv extruded muaj xws li cov kav dej, pas nrig, cov nplooj ntawv, cov yeeb yaj kiab, fibers, thiab lwm yam. Kev txhaj tshuaj molding yog feem ntau siv ua thiab molding txoj kev tom qab extrusion.
