1、PBT 成型时的注意事项重要 在使用“Duranex”应的产品目录、技术资料及产品安全数据手册（MSDS）。 危险 “Duranex”颗粒撒落在道路或地面上时，容易使行人滑倒，请及时清扫。 “Duranex”的灭火方法：除用水以外，还可使用泡末灭火剂、干粉灭火剂或碳酸气等。成型时的注意事项 必须对材料进行预干燥，干燥条件如右 干燥温度并非是干燥机的设定温度，请确认颗粒温度是否在右表所示的温度范围内。为了防止在成型中吸水，建议使用漏斗式干燥机（95105）。 为了防止树脂分解，请按下列条件设定树脂温度及机筒内的滞留时间。1.最佳树脂温度：240 260 （不得超过 280） 2. 料筒内滞留极限
2、时间滞留时间料筒温度非阻燃等级 阻燃等级240 60 分钟以内 30 分钟以内260 30 分钟以内 10 分钟以内（以上只是作为参考的范围值，还会因各种条件的不同而发生变化。） 当树脂出现分解或有分解的迹象时，请降低机筒温度，并将机筒内的材料彻底排清。在作业时请带好防护眼睛，不要将手、脸靠近喷嘴处。 成型中断时，请将机筒内的材料完全射出，关闭机筒的加热器电源。 请勿混入本公司推荐外的着色剂、添加剂及异种牌号的树脂。 在替换材料时，必须先用聚乙烯（PE）或聚苯乙烯（PS）替换 FR-PET，然后才能替换其他的树脂。 在工局部或完全通作场所应为风。 其它 在此所提供的信息，只是我们在实际使用该材
3、料时所得知的，并非是我们对材料进行全面确认后的信息，故本公司对上述信息的正确性及安全性不负任何责任。 树脂颗粒撒落在地面、排水系统等地方时，会对河流、海洋造成环境污染，请务必作好回收工作。干燥温度 干燥时间105 8 小时120 5 小时140 3 小时对部分的品级不一定合适，请参考技术资料。 Consult the appropriate bulletins for the grade to be used, technical data or Material Safety Data Sheet (MSDS) for proper use of DURANEX.
