PC塑料材料具有良好的抗冲击性和韧性
产品详细信息
具有良好抗冲击性和韧性的PC塑料 PC塑料成型条件：
1.非晶态材料，热稳定性好，成型温度范围宽，流动性差。吸湿性低，但对水敏感，必须干燥。成型收缩率小，易发生熔融开裂和应力集中。因此，应严格控制成型条件，塑料零件必须退火
2.对于熔融温度高、粘度大、大于200g的塑料零件，建议使用加热型延伸喷嘴
3.冷却速度快，模具浇注系统基于厚短原则。建议设置冷段塞井，浇口应大，模具应加热
4.如果材料温度过低，会导致材料短缺，塑料件会变钝，材料温度容易溢出，塑料件会起泡。当模具温度较低时，收缩率、伸长率和抗冲击性较高，弯曲、压缩和拉伸强度较低。当模具温度超过120度时，塑料件冷却缓慢，容易变形并粘在模具上
5.塑料部分的墙壁不应太厚，塑料部分的墙壁不应太厚，应均匀一致，避免尖角和缺口，避免尖角和缺口。
< Features: halogen-free flame retardant, PC Plastic Material With Good Impact Resistance And Toughness Translucent fiber reinforced fire-retardant PC, flame-retardant, high temperature resistance, impact resistance, good toughness, PC plastic material PC plastic molding conditions: 1. Amorphous material, good thermal stability, wide molding temperature range, and poor fluidity. Low moisture absorption, but sensitive to water, it must be dried. The molding shrinkage rate is small, and melting cracking and stress concentration are easy to occur. Therefore, the molding conditions should be strictly controlled, and the plastic parts must be annealed. 2. For plastic parts with high melting temperature and high viscosity, larger than 200g, it is advisable to use a heated extension nozzle. 3. The cooling rate is fast, and the mold gating system is based on the principle of thick and short. It is advisable to set up a cold slug well, the gate should be large, and the mold should be heated. 4. If the material temperature is too low, it will cause shortage of material, plastic parts will be dull, and the material temperature will be easy to overflow, and the plastic parts will foam. When the mold temperature is low, the shrinkage, elongation, and impact resistance are high, and the bending, compression and tensile strength are low. When the mold temperature exceeds 120 degrees, the cooling of the plastic part is slow, and it is easy to deform and stick to the mold 5. The wall of the plastic part should not be too thick, it should be uniform, avoid sharp corners and gaps ContactnowformoredetailsaboutPC plastic material with good impact resistance and toughness.
