聚丙烯颗粒中色粒产生原因分析及对策

Analysis and Countermeasures of Color Pigment in Polypropylene Particles

聚丙烯颗粒在实际生产过程中,由于受工艺和操作的影响,很容易产生带色的颗粒。这些颗粒直接降低了以其为原料所制作产品的质量和美观,直接降低了产品的销量。色粒的产生主要发生在造粒开车过程、颗粒生产过程、换网过程、颗粒运输和包装过程。对这些过程产生色粒的主要原因进行认真分析,并提出有效的改善对策,希望对实际造粒中降低色粒产生率可以起到促进作用。

Polypropylene particles in the actual production process, due to process and operation of the impact, it is easy to produce colored particles.These particles directly reduce the quality and aesthetics of the products made from them, directly reducing the sales volume of the products.Color particles occur mainly in the process of granulation drive, particle production process, the process for changing network, particle transport and packaging process.The main reason for producing color particles in these processes is analyzed carefully, and the effective countermeasures are put forward.It is hoped that the reduction of color particles in the actual granulation can be promoted.
