PC plastics — recycled polycarbonate (PC) process process/workflow
PC plastics — recycled polycarbonate (PC) process process/workflow
PC polycarbonate (PC) | technology 文章 | Daoqin plastics raw materials
本文 will detailed introductionpolycarbonate (PC) （PC）material property can features, application areas and processing process, is material selection and product design provide 参考.
detailed introduction
PC plastics Scientific Names polycarbonate (PC), belongs to non crystallization plastics, in engineering upper application relatively is 广泛. more is used for made as textile parts, automotive 车灯, electrical device 械, device and optical device and other and other, as is types content very high plastics raw materials, its in type and processing process in is non complex, process process/workflow non 常严格, has this can made as property can relatively good PC product. lower 面我们就 看看 polycarbonate (PC) process process/workflow is how to.
need selection good Chi Mei PC plastics, currently PC has transparent, has transparent, color is 各异, in selection 时候一定 need separation 开, in property can upper has modified, according to need selection, ratio textile parts need use modified, 而车灯都 is need film. 清洗, need attention/notes 清洗各 color PC, 做退镀处理, rear dry, from extrusion machine production. according to color production, has PC呈现黄 color, can production 瓷白, transparent can production transparent, other can add color agent or is other material. in extrusion and pelletizing process in, need use specialized extrusion machine pelletizing, 但考虑 to PC容 easy aging causes, therefore need more 次 回 material, pelletizing need heavy.
another is Chi Mei PC plastics type, type has very more features need attention/notes, type good bad effect/influence to PC plastics property can, ratio temperature degree, water separation content and other, need control, water amount low, strong/high degree large, for use process in is has very large effect/influence.
PC plastics in industrial upper is recycled polycarbonate (PC), versus its excellent property can, function, full is is can substitute/replace very more type product.
[材 material basic parameters ]
| density | 1.20 g/cm³ |
| 玻璃化转变 temperature degree | 147°C |
| heat deflection temperature (HDT) | 130~140°C |
| tensile strength | 55~75 MPa |
| notched impact strength | 600~850 J/m |
| light transmittance | 88~91% |
| flame retardant rating | UL 94 V-2 |
| molding shrinkage | 0.5~0.7% |
core advantages
- high transparency degree: light transmittance can 达89% above, is excellent transparent engineering material
- 卓越 impact resistant property: notched impact strength high 达600-850 J/m, is 普通玻璃 250倍
- excellent dimensional stability: molding shrinkage low （0.5-0.7%）, products dimensions 精确
- wide use temperature degree scope/range: can in -60°C至120°C scope/range inner long use
- excellent electrical insulation property can: volume resistivity high, suitable for electronics electrical field/area
- good flame retardant property: tool has self-extinguishing property, can UL 94 V-2 grade
application areas
electrical outer housing/shell, machine outer housing/shell, LED lamp covers, light 盘, connectors, 开关
lamp covers, table/sheet sheet/plate, 保险杠, 天窗, 车窗玻璃
cationic light sheet/plate, light sheet/plate, 隔音屏障, safety anti 护窗
liquid device, device 械, bottle, 婴儿保育箱
眼镜 sheet/slice, versus machine 镜头, micro sheet/slice, light
injection molding processing process
- drying 处理: 120°C drying 4-6 small 时, moisture content ≤0.02%
- material temperature degree: 260~310°C（ according to molecular weight adjustment ）
- mold temperature degree: 80~120°C（ high mold temperature can obtain more good surface quality ）
- injection pressure: 80~140 MPa
- injection speed degree: in and other slow, 避免喷射 and scorching/burn marks
- precautions: PC for 缺口敏感, products design 应避免尖角
