Description描述

 

THYOSIL CXP5045 is a multifunctional polymer specially designed to restore molecular weight and IV (intrinsic viscosity) in degraded polymers.

THYOSIL CXP5045 allows to upgrade low quality recycle and can be used during processing to increase the melt strength of polyesters or polyamide. THYOSIL CXP5045 also has high epoxy functionality, this allows for rapid reaction with condensation thermoplastics, resulting in higher molecular weight.

Processing conditions加工条件

 

Operation操作

Procedure步骤

Pre-drying

预干燥

Pre-dry the base plastic at manufacturer’s recommended conditions.

推荐下预干燥基础塑料。

In some instances small amounts of THYOSIL CXP5045 can be compensated for poor or incomplete drying, thus bringing robustness and saving to your operations.

在某些情况下,添加少量的THYOSIL CXP5045可以补偿不良或不完全的干燥,从而为您的操作带来方便和节省操作。

Hygroscopicity: there is no evidence of bulk absorption of moisture over extended periods of time for THYOSIL CXP5045.

At normal conditions of temperature and relative humidity its surface reaches equilibrium saturation through adsorption at less than 0,25% of moisture.

At extreme conditions its surface reaches equilibrium saturation at less than 0,50% of moisture.

This means that THYOSIL CXP5045 can generally be processed without any drying, even after long exposure to drastic conditions bringing no more than 5ppm moisture per every 0,1% used.

吸湿性:THYOSIL CXP5045在长时间内没有大量吸收水分的迹象。在正常的温度和相对湿度条件下,其表面通过吸附小于0.25%的水分达到平衡饱和度。

在极端条件下其表面水分,在小于0.50%达到平衡饱和。这意味着即使经过长时间暴露于剧烈的条件下,THYOSIL CXP5045通常也可以进行加工处理,每0.1%使用不超过5ppm的水分。

Ins systems where moisture sensitivity is extreme, THYOSIL CXP5045 can be dried in a desiccant dryer ant 30°C for 1 hour, prior to use.

在潮湿敏感度极高的系统中,THYOSIL CXP5045可以在干燥剂干燥器中于30℃ 干燥1小时,然后再使用。

Extruder/injection molder temperature profile

挤出机/注塑机温度曲线

Where feeding solid THYOSIL CXP5045 in any solid form, except masterbatch, into the first zone of the extruder or infection molder, we recommend to operate this zone at 20°C to 40 °C lower temperature than normal. This will prevent early melting and agglomeration of the additive.

在将固体形式除母粒之外的固体THYOSIL CXP5045进入挤出机或感染模塑机的第一区域内,建议比常温低 ,在20℃至40℃的温度下操作该区域。 这将防止添加剂的早期熔化和附聚。

All other zones should employ normal processing condition as recommended by the plastic’s manufacturer.

所有其他区域应采用塑料制造商推荐的正常加工条件。

Additive thermal stability

添加剂热稳定性

THYOSIL CXP5045 is thermally stable up to 320°C. Above this temperature additive decomposition may occur.

THYOSIL CXP5045320°C以下是热稳定的。 高于此温度可能会发生分解。

Residence time

停留时间

THYOSIL CXP5045 reacts quickly. Its reaction will be over 99% complete if at least 3 min residence time is provided at 200°C in a well-mixed system. Alternatively, 45 sec residence time at 280°C will provide 99% completion.

THYOSIL CXP5045快速反应。 如果在200℃下在充分混合的系统中至少提供3分钟的停留时间,其反应将达到99%以上。 或者,在280℃下停留时间为45秒将完成99%。

These limits accommodate most extrusion and injection molding processed for the recommended thermoplastics and applications.

这些限制适用于为推荐的热塑性塑料和应用而加工的大多数挤出和注塑。

For use in polymerization reactors where residence time is over 5 minutes, see recommendations in section “Methods of Dosage”.

用于停留时间超过5分钟的聚合反应釜中,请参见“剂量方法”一节中的建议。

 

· THYOSIL CXP5045 should not be processed at temperatures higher than 320°C

· THYOSILCXP5045不应在高于320°C加工温度。

 

Extruder pressure effects挤出机压力效应

 

The use of THYOSIL CXP5045 in reactive extrusion or reactive injection molding operations increases significantly the molecular weight, this lead to an increase in melt viscosity, which in turn raises the pressure observed in the equipment.

The table below exemplifies the large increases in die pressure that are observed in PET as THYOSIL CXP5045 is added to a large extruder. Similar increases are expected in other plastics.

在反应性挤出或反应性注射成型工具中使用THYOSIL CXP5045显着增加了分子量,这导致熔体粘度的增加,从而提高了设备中观察到的压力。下表列举了将THYOSIL CXP5045加入到大型挤出机中时在PET中观察到的模具压力的大幅增加。 预计其他塑料类似增长。

The pressure increases both at the die and in front screen system may be 25% to 100% higher than typical operating pressure for higher usage levels. Instantaneous pressure variations and spikes are due to large instantaneous changes in melt viscosity. At constant temperature, changes in melt viscosity are often due to variable feed rate and/or poor mixing.

在模具和前屏幕系统中的压力增加可以比用于较高使用水平的典型操作压力高25%至100%。瞬时压力变化和尖峰是由于熔体粘度的瞬间变化很大。 在恒定温度下,熔体粘度的变化通常是由于可变的进料速率和/或混合不良。

 

The pressure and power draw changes with fluctuations in feed rate are calculated on the table below.

Troubleshooting故障排除

 

Ø In case of unexpected high pressure:Ø如出现意想不到的高压:

1) Decrease the feed rate of THYOSIL CXP5045.降低THYOSIL CXP5045的进料速度。

2) Decrease the RPM. This decrease pressure on single screw extruders and flood-fed twin-screw extruders, and will decrease hating on starve-fed twin-screw extruders.)

    降低转速。 这对单螺杆挤出机和挤压双螺杆挤出机的压力降低,并且将减少对供给双螺杆挤出机的不适

3) Slowly increase the temperature, starting from the die and then from the last to the zone.

      缓慢升高温度,从模头开始,然后从最后到达区域。

4) With pressure under control, increase the THYOSIL CXP5045 feed slowly.

     在控制压力下,慢慢增加THYOSIL CXP 5045进料。

5) For steady operation follow recommendations given in the section “extruder pressure effects”

         为了稳定运行,请参阅“挤出机压力效应”一节中给出的建议
