PBT成型时的注意事项.doc

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。 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。1.2.料筒内滞留极限时间料筒温度滞留时间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。）最佳树脂温度：240 260 （不得超过280） 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。 Consult the appropriate bulletins for the grade to be used, technical data or Material Safety Data Sheet (MSDS) for proper use of DURANEX.If DURANEX pellets lie scattered on the passage or floor, you may slip and stumble. Clean the passage or floor immediately.If DURANEX is caught on fire, use water, foam fire extinguishing system, chemical powder fire extinguishing system or carbon dioxide fire extinguishing system.Predrying TemperaturePredrying Time105C8hrs.120C5hrs.*140C*3hrs.*This condition does not apply to some grade ofDURANEX. Refer to the brochure.Predry under the following conditions.To keep the material dry, use of hopper dryer is recommended (95 - 105C).To prevent decomposition of material, follow the recommended conditions below.1) Optimum material temperatures : 240 - 260C Do not heat above 280C.2) Limit in-cylinder retention time : Cylinder TemperatureMaximum Residence TimeSlow Burning Type Flame Retarded Type240C60min.30min.260C30min.10min.(The above conditions give a standard, and may vary under different conditions.)In case of decomposition of the material or any fear of decomposition, reduce the cylinder temperature and purge (discharge) the material from the cylinder. During purging,wear safety goggles and keep hands and face away from the nozzle section.When shutting down the molding operation, purge DURANEX and turn the heater off.Do not mix any colorants, additives or resins of other brands with DURANEX except those we recommend.When DURANEX is replaced by other material, DURANEX should be purged by Polyethylene (PE) or Polystyrene (PS).Keep the work place ventilated locally or entirely during operation.The information contained herein is all the data available at present for using this material.
