聚碳酸酯(PC)特性:
(1)PC是一种非晶体工程材料,具有特别好的抗冲击强度、热稳定性、光泽度、抑制特性、阻燃特性以及抗污染性。
(2)PC有很好的机械特性,但流动特性较差,因此这种材料的注塑过程较困难。如果塑件要求有较高的抗冲击性,那么就使用低流动率的PC材料;反之,可以使用高流动率的PC材料,这样可以优化注塑过程。
(3)PC塑胶原料它是一种新型的热塑性塑料,透明的度达90%,被誉为是透明金属。它刚硬而具有韧性,具有较高的冲击强度,高度的尺寸稳定性和范围很宽的使用温度、良好的电绝缘性能及耐热性和无毒性,可以通过、挤出成型。
(4)PC塑料的热性能优异,可在-100℃-130℃之间长期使用,脆化温度在-100℃以下。
(5)虽然聚碳酸酯具有耐开裂和耐药品性较差,高温易水解,与其它树脂的相容性差,润滑性能不好,但是,可以通过加入其它的树脂或者无机填充剂进行改性,从而获得十分优异的性能。
PC加工要注意哪些事项?
PC塑胶原料的吸水率较大,加工**定要预热干燥,纯PC干燥120℃,改性PC一般用110℃温度干燥4小时以上。干燥时间不能**过10小时。一般可用对空挤出法判断干燥是否足够。再生料的使用比例可达20%。在某些情况下,可的使用再生料,实际份量要视制品的品质要求而定。再生料不能同时混合不同的色母粒,否则会严重损坏成品的性质。
PC塑料制品由于成本及其它方面的原因,多用改性材料,特别是电工产品,还须增加防火性能,在阻燃的PC和其它塑料合金产品成型时,对注塑机塑化系统的要求是混合好、耐腐蚀,常规的塑化螺杆难以做到,在选购时,一定要预先说明。
日本出光株式会社(以下简称日本出光),创立于1911年,以销售润滑油产品起家,经过九十余年的不断努力,业务范围已经扩展到了石油行业的各个领域,包括石油的开发(探矿)、石油制品的运输、的冶炼与销售、石油化工以及其他服务(加油站等),成为日本的石油综合集团,在日本拥有近六千家加油站,遍及日本各地,也是世界**。日本出光拥有5大子集团:出光石油开发(株)、出光运输(株)、出光兴产(株)、出光石油化学(株)和阿波罗服务(株)。出光兴产(株)主要负责日本出光石油产品的冶炼和销售,其资本金达到388亿日元,共雇佣员工3652人,在日本国内有22家分支机构,在海外有23家事务所。
Main manufacturers of PC:
PC is an engineering plastic developed in 1960s. At present, the main global manufacturers include Makrolon PC of Bayer, Lexan PC of SABIC, tarflon PC of Japan, iubolon PC of Mitsubishi of Japan, panlite PC of emperor of Japan, Sumitomo chemical PC of Japan, LG PC of Korea, PC of Holland, etc. However, the domestic independent PC production capacity has been small, such as Ningbo Fengfeng, Shandong Luxi Chemical, Mitsubishi Chemical, etc. at present, the main domestic construction projects are Sino foreign joint ventures, such as Bayer and Shanghai Huayi Group investing in the production line in Shanghai Chemical Industry Park, and Japanese emperor building in Jiaxing, Zhejiang Province. In Taiwan, there are Taiwan Qimei PC, Taiwan huashiguang PC, Taiwan shengxiao (Styron) PC, etc.
