In late January 2020, the polypropylene unit operation team of juzhengyuan Technology Co., Ltd. actively carried out technical innovation and developed a thin-wall injection plastic m60n with high melting finger and high transparency. In view of the fact that PP with a melt index of more than 40g / 10min has never been produced before, before trial production, the operation team shall make detailed adjustment and improvement to the production plan, and formulate the possible abnormal situation response plan; during trial production, each process data shall be carefully analyzed and set, and key indicators shall be strictly controlled, so as to successfully produce new PP thin-wall injection plastic m60n, and put it into the market on trial
