塑料助剂选用配方要点
(1)塑料粒子的品种的选择
(1) selection of the varieties of plastic particles

塑料粒子要选择与改性目的性能最接近的品种,这样做的好处是可以节省助剂的添加量,以降低制作成本和减少工艺流程。
In order to reduce the production cost and reduce the process flow, the plastic particles should choose the varieties closest to the modified purpose.
最常见的例子:想要得到耐磨改性的品种,塑料粒子(树脂)要首先考虑选择三大耐磨树脂PA、POM、UHMWPE;再如透明改性,树脂要首先考虑选择三大透明树脂PS、PMMA、PC。
The most common example: to get a variety of wear-resistant modified, plastic particles (resin) should first consider the choice of three major wear resistant resin PA, POM, UHMWPE; again such as transparent modification, the resin should first consider the choice of three large transparent resin, PS, PMMA, PC.

(2)树脂流动性的选择
(2) choice of resin fluidity
配方中各种塑化材料的粘度要接近,以保证加工流动性。对于粘度相差悬殊的材料,要加过渡料,以减小粘度梯度。
The viscosity of various plasticizing materials in the formulation is close to ensure processing fluidity. For different materials with different viscosity, transitional materials should be added to reduce the viscosity gradient.

(3)塑料分成高流动性塑料、低流动性塑料和不流动性塑料
(3) plastics are classified into high mobility plastics, low mobility plastics and illiquid plastics.
具体如下:
The following is as follows:
高流动性塑料——PS、HIPS、abs、PE、PP、PA等。
High mobility plastics -- PS, HIPS, ABS, PE, PP, PA and so on.
低流动性塑料——PC、MPPO、PPS等。
Low fluidity plastics - PC, MPPO, PPS and so on.
