灵活而万能的LFT技术
ProTec的LFT技术适合于生产种类繁多的物料，可以选
择各不相同的增强纤维以及各不相同的高分子基质物料，其
中许多都可以在LFT制造过程中直接混合。即使难于处理的
配对物料如碳纤维和PP也可以可靠地进行加工。ProTec的总
部位于德国Bensheim，安装有一条技术领先的多功能拉挤生
产线，能够满足特定客户的应用测试要求，进行基本的加工
和原料开发。
生产线的主要配置，是装备了SOMOS® Gramix S 称重
计量系统的高性能混合挤出机，计量系统可以精确称量和混
合多达九种组份的原料。因此，高分子基体的独特配方可以
用非常灵活的方式在工艺过程中直接生产出来，可变化的空
间非常大。回收再生的物料和附加的填充料也同样包括在物
料的配方中。
通过拉挤方法生产LFT组合料，包括将纤维带连续地拉
伸并通过高分子材料融体，这样单独的纤维浸渍了高分子材
料基材，一旦合成的纤维/高分子材料带冷却下来，就对其进
行造粒。为了完成浸渍加工，第一道工序就是将纤维从特别
设计的筒子架上引导向浸渍模头。在模头后方是下游设备，
热的纤维/高分子材料带最终由压型系统定型，例如成为圆形
条状或扁平带状。在采用适合于高分子材料的冷却单元将条
带冷却后，还要通过拉伸机，拉伸机控制着条带连续地通过
整条生产线。
ProTec提供一站式服务，可以按照特殊要求进行专门订
制，设计和提供全套交钥匙生产线，包括物料开发和测试，
以及在客户的生产现场调试运行和交付使用。生产线可以生
产出纤维含量重量百分比高达60 %的产品，产量高达
1,200 kg/h 。任何传统的热塑性塑料或甚至生物高分子材料
如PLA（聚乳酸）都可以作为基体使用，玻璃纤维、钢纤维
或碳纤维都可以作为增强纤维使用。
LFT生产线及所有模块的操作都通过中央生产线控制器
完成。可设定不同的参数，包括生产线速度、挤出机的产量
和粒子切粒长度。此外，根据不同的用途，上下游设备的参
数也可以结合到控制系统中来。这些上下游设备包括进料组
份的干燥、输送、调配和混合单元。

components. As a result, a very wide range of individual formu-
lations of the polymer matrix can be produced very flexibly di-
rectly in the process. Recycled material and additional fillers
may likewise be included in the material formulation.
Producing LFT compounds by pultrusion involves continuously
drawing fibre strands through a polymer melt, so impregnating
the individual fibres with the polymer matrix and, once the re-
sultant fibre/polymer strands have cooled, pelletising them. In
order to be impregnated, in the first process step, the fibre
strands are guided from the creels by a specially designed guide
into the impregnation die. Downstream from the die, the hot fi-
bre/polymer strands are then finally shaped, for example into
round strands or flat tapes, in a profiling system. After cooling
in a cooling unit adapted to the polymer, they additionally pass
through a puller which controls the continuous passage of the
strands through the line.
ProTec is a one-stop shop capable of designing and supplying
complete turn-key lines tailored to specific requirements from
materials development to testing and commissioning on the cus-
tomer's premises. The lines are capable of handling fibre con-
tents of up to 60 wt.% and throughputs of up to 1,200 kg/h.
Any conventional thermoplastics or even biopolymers such as
PLA (polylactic acid) can be used as the matrix, while glass, steel
or carbon fibres can be used as the reinforcing fibres.
The LFT line and all its modules are operated from the central line
controller. Variable parameters include line speed, extruder
throughput and pellet chopping length. Additional functions, lo-
cated upstream or downstream depending on application, may
also be incorporated into the control system. These include dry-
ing, conveying, dispensing and mixing of the feed components.

诺信公司（Nordson）将向位于中国江苏省的超大规模
PET树脂工厂江阴澄高包装材料有限公司提供十六套商标为
BKG® CrystallCut® 的已获得专利的造粒系统，该工厂计划
本年度投产。这一大型项目表明亚洲市场对造粒系统的关注
在加强，在2016年中国国际橡塑展诺信的展台上，这一点将
被显而易见地得以呈现。（展台号 W2-J01）
与标准的PET聚合系统比起来，诺信的CrystallCut 工艺
提供了实实在在的能源节省效果，这是由于将PET聚合系统
融熔聚合物的热能应用到了随后的结晶化过程中去。在江阴
Nordson Corporation will supply sixteen of its process-patented
BKG® brand CrystallCut® pelletizing systems for a mega-scale
PET resin plant scheduled for startup this year by Jiangyin Chen-
gold Packaging Materials Co., Ltd. in Jiangsu Province, China.
The big project reflects the intensified focus on pelletizing sys-
tems for the Asian marketplace that will be evident in Nord-
son’s exhibit at Chinaplas 2016 (Stand W2-J01).
Nordson’s CrystallCut process provides substantial energy sav-
ings in comparison with standard PET polymerization systems
