Lub hauv paus tseem ceeb ntawm PS hniav moldings yog Polystyrene (PS). Nws ua haujlwm raws li cov qauv txheej txheem ntawm molding, txiav txim siab cov khoom lub teeb yuag, moldability, thiab rigidity.
Txhawm rau txhim kho kev ua tau zoo thiab ua kom haum rau ntau hom kev tsim sab hauv, cov khoom siv me me ntawm cov khoom siv ntxiv yog feem ntau suav nrog thaum lub sijhawm tsim khoom. Cov no suav nrog:
Toughening Agents: Cov no txhim kho kev cuam tshuam thiab toughness, yog li txo qhov kev puas tsuaj los ntawm kev sib tsoo los yog thaum lub sijhawm teeb tsa.
Antioxidants / Stabilizers: Cov no txhim khu kev tiv thaiv tshav kub, lub teeb, thiab kev laus, yog li txuas ntxiv cov khoom siv lub neej.
Fillers (piv txwv li, talc hmoov, calcium carbonate): Cov no tswj hardness, txhim kho cov yam ntxwv, thiab pab tswj cov nqi tsim khoom.
Cov Khoom Siv Hniav Hniav (xws li, thermal hloov zaj duab xis, laminates, lossis cov tshuaj tsuag txheej): Cov no muab cov khoom zoo nkauj zoo nkauj-xws li ntoo lis, pob zeb zoo nkauj, los yog cov xim muaj zog-thaum ib txhij txhim kho kev puas tsuaj, ya raws, thiab staining.
Thaum PS ua haujlwm tseem ceeb hauv cov khoom siv, lwm cov khoom xyaw ua haujlwm ua cov khoom siv ntxiv - ua haujlwm rau kev ua haujlwm lossis kho kom zoo nkauj -thiab sib sau ua ke txiav txim siab tag nrho cov kev ua tau zoo thiab kev zoo nkauj ntawm cov hniav moldings.
