消除色母同母料混合不均的影响
塑料母料同色母混和不好也会使产品颜色变化无常。将母料及色母机械混合均匀后,通过下吸料送入料斗时,因静电作用,色母同母料分离,易吸附于料斗壁,这势必造成注塑周期中色母量的改变,从而产生色差。对此种情况可采取原料吸入料斗后再加以人工搅拌的方法解决。现在有很多公司采用喂料机来加入色母,这样节省了大量人力,并且为色差控制提供了很大的帮助,但不少公司因使用不当,结果往往难以令人满意。固定转速下喂料机加入色母的多少取决于塑化时间,而塑化时间本身是波动的,有时波动甚至还比较大,因此要保证恒定的加料量,需将喂料机加料时间加以固定,且设定时间小于最小塑化时间。在使用喂料机时需注意,因喂料机出口较小,使用一段时间后,可能会因为喂料机螺杆中积存的原料粉粒造成下料不准,甚至造成喂料机停转,因此需定期清理。

清洗料管 Purge compound |
需使用PP或 PE清洗干净机台螺杆,且把机台射嘴彻底清除干净Please make sure you that you have cleaned the machine screw with PP or PE, and put the machine nozzle thoroughly clean. |
|||||||
着色 Coloring
|
请选择以PE或EVA为基材之色母,切勿使用以PVC为基材者。另外加工时请采用较高的螺杆转速和较高的背压,才能让着色剂达到较好的分散效果Please select color master batch on PE or EVA material with the exception of PVC.Higher screw speed are backpressure are needed for better colorant dispersion. |
