PC塑料树脂材料

产品详细信息

PC塑料树脂材料

产品详细信息PC中文名称聚碳酸酯优点：
1。具有较高的强度和弹性系数，较高的冲击强度和较宽的工作温度范围

2。高透明度和自由染色

3。H.D.T.很高

4。良好的抗疲劳性能

5。良好的耐候性

6。优良的电气特性

7。无臭无臭，对人体无害，符合健康安全要求

8。成形收缩率低，尺寸稳定性好

PC成型条件和注意事项。当注射压力较大、管内温度过高或停留时间较长时，易发生热分解、变色，降低物理性能。需要注意的是，模具温度为85℃-120℃

[1]湿度控制在0.02%以下

[2]在120℃干燥4小时，不超过150℃

2。尤其难以形成厚的成品，因为成品容易产生残余应力，这将导致未来的破裂。因此，建议使用粉末硅作为脱模剂，而不是液体脱模剂

3。成型需要高温高压，必须使用螺杆式成型梭

4。材料在使用前应充分干燥

5。闸门和转轮的设计应具有较小的流动阻力

6。模制产品的设计应接近厚度，避免金属零件的镶嵌。此外，收缩倾角必须大于2°

7。成型收缩率为0.4-0.7%，比重为1.2-1.5

8。加热温度230-310℃，模具温度80-120℃，料管温度260-310℃，顶出温度280-320℃，注射压力800-1500kg/cm2，低工作温度260℃。

9。使用除湿干燥器，干燥温度为105-120°C（低于0.02-0.03%），需要2-4小时，物料管温度为260-270°C；第二阶段为260-270°C；第三阶段为240-250°C；第四阶段为220-230°C；模具表面温度为40-60℃。

10。温度设定：喷嘴230-300℃，前段260-280℃，中段265-275℃，后段250-270℃；螺杆转速40-160rpm，模具温度80-120℃，注射压力1000-1400kg/cm2，背压5-15kg，螺杆压缩比2.4，L/DO 15-24

PC molding conditions and precautions

1. When the injection pressure is large, the temperature in the tube is too high or the residence time is long, it is easy to thermally decompose, discolor and reduce the physical properties. It should be noted that the mold temperature is 85℃-120℃.

〔1〕Moisture is controlled below 0.02%

〔2〕Dry at 120℃ for 4 hours, do not exceed 150℃

2. It is especially difficult to form thick finished products, because the finished products are prone to residual stress, which will cause future ruptures. Therefore, it is advisable to use powdered Silicon as the release agent, not liquid release agent.

3. The forming requires high temperature and high pressure, and a screw-type forming shuttle must be used.

4. The material should be fully dried before use.

5. Gate and runner design should have small flow resistance.

6. The design of the molded product should be close to the thickness, and avoid inlaying of metal parts. Furthermore, the retraction inclination must be more than 2°.

7. The molding shrinkage rate is 0.4-0.7%, and the specific gravity is 1.2-1.5.

8. Heating temperature 230-310℃, mold temperature 80-120℃, material tube temperature 260-310℃, ejection temperature 280-320℃, injection pressure 800-1500kg/cm2, low operating temperature 260℃ °C.

9. Use a dehumidifying dryer, the drying temperature is 105—120°C (below 0.02—0.03%), it takes 2—4 hours, and the temperature of the material pipe is 260—270°C; the second stage is 260— 270°C; the third stage is 240-250°C; the fourth stage is 220-230°C; the mold surface temperature is 40-60°C.

10. Temperature setting: nozzle 230-300℃, front section 260-280℃, middle section 265-275℃, rear section 250-270℃; screw speed 40-160rpm, mold temperature 80-120℃ , The injection pressure is 1000-1400 kg/cm2, the back pressure is 5-15kg, the screw compression ratio is 2.4, and the L/DO is 15-24.
