山东模具制造厂家:塑料模具加工中气体的来源
Shandong Mould Manufacturer: Source of Gas in Plastic Mould Processing
塑料模具加工进程中,能够会呈现塑料制品填充缺乏,内应力高,存在气泡等等景象,这很能够是塑料模具的排气成绩。
In the process of plastic mould processing, there will be a lack of filling plastic products, high internal stress, the existence of bubbles and so on, which can be the result of plastic mould exhaust.
塑料模具排气不良,型腔中的气体遭到紧缩,发生很大的反压力,正是这种反压力阻止了熔融塑料的正常疾速充模,使得注塑成型变得困难。那麼塑料模具加工中这些气体的来源是来自哪里呢?
Plastic mold exhaust is not good, the gas in the cavity is compressed, and a lot of back pressure occurs. It is this back pressure that prevents the normal rapid filling of molten plastic, making injection molding difficult. Where do these gases come from in plastic mould processing?

1浇注零碎和模具型腔中存有的空气。
1. Air in casting fragments and mould cavity.
2.由于注塑时温渡过高,某些性质不波动的塑料发作分解所发生的气体。
2. Gases occurring during the decomposition of certain plastics which do not fluctuate due to excessive temperature during injection moulding.
3.有些原料含有未被枯燥扫除的水分,它们在低温下气化成水蒸气。
3. Some raw materials contain water that has not been swept away by dryness. They are gasified into steam at low temperatures.
4.塑料原料中的某些添加剂挥发或互相化学反响生成的气体。
4. Gases generated by volatilization or chemical reaction of some additives in plastic raw materials.
