涤纶短丝装置增量改造的关键技术

在消化吸收引进线的基础上,采用自行开发的工艺技术,实施对８０年代直接纺短丝装置进行改造,主要技术关键是纺丝采用低阻尼中心环吹,后处理采用独立变频传动等,使生产能力增加９０%以上,改造的投资仅为引进线的２５%。

KEY TECHNOLOGY OF POLYESTER STAPLE PLANT INCREMENT MODIFICATION

Basing on digesting the imported line and using own technology,modification is made on the direct spinning plant built in 80s. The key technology is to use low resistance out-flow quench air system for spinning and independent inverter for drawing drive. The sum of modification is only 25% of those for imported line,but the capacity increases over 90% .
