PVC電纜料造粒機

我們常用的聚氯乙烯膠料都是顆粒狀的，它是多組份的塑料，除了前面講的聚氯乙烯樹脂粉以外，還必須加入增塑劑增加它的流動性，加入穩定劑提高它的熱穩定性，加入潤滑劑提高它的脫模性，以及填料，著色劑，偶聯劑等；因為各組份的含量不同，就形成了各種機械性能差異很大的不同硬度的PVC顆粒；PVC顆粒大體分為：軟質PVC，硬質PVC。外觀    因PVC膠料所含的組份不同，它的外觀差異很大。有的透明如玻璃，也有不透明的；有的非常柔軟，耐折迭，有類橡膠彈性；也有硬質的，象ABS，機械性能優良，可以做工程材料。大部分的PVC有輕微毒性，但不致于一接觸就能種毒；也有食品級的PVC膠顆粒。

PVC cable granulator.

We often use the PVC plastic material is granular, it is more plastic components, in addition to speak in front of the PVC tree powder, must also join plasticizer increase its liquidity, add stabilizer to improve its thermal stability, add lubricant to improve its release, as well as the packing, colorants, coupling agent, etc.;Because the content of each component is different, the PVC granules with different hardness are formed.PVC particles are generally divided into: soft PVC, hard PVC.The appearance is very different due to the different components of PVC.Some are glassy and opaque;Some of them are very soft, folding, and rubber elastic;Also has the hard, elephant ABS, the mechanical property is good, can do the engineering material.Most PVC is mildly toxic, but can be poisonous without contact;There are also food grade PVC glue particles.
