你了解用PBT做的纺粘或者熔喷布吗?

这种物性的PBT,可以做纺粘布吗?但是价格比PP要高。熔喷的话,这种PBT熔融指数达不到把,我不太了解,只是学习阶段。

喷丝板清洗方法


熔纺喷丝板的清洗,可用下列各种方法:

1、锻烧法:在自动控温箱式炉中进行。煅烧温度450~480℃,当温度超过480℃时会有过热蒸汽通过炉膛,吹灭火焰,降低温度,以免烧损喷丝板。

2、盐浴法:盐浴大致成分为NaNO345%-NaNO245%-NaOH10%,盐浴熔点~200℃,使用温度450~500℃。盐浴在该温度时呈强氧化性状态,将聚合物氧化成CO2和H2O,作用过程相当快,约60~90分钟即可完成。从盐浴出来后,用熟热水清洗除盐,再用稀硝酸除去表面氧化膜,然后清水漂洗,超声清洗、干燥。

3、普鲁西丁流化床清洗法:流化床温度450~500℃,以热气流运载氧化铝粉粒,使粘附在喷丝板上的聚合物在气流中受冲刷剥离并分解氧化(约70%的聚合物直接分解,少量的碳粒生成CO),被排出室外。无机物如二氧化钛等留于板面,最终也随气流排出。此法的好处是喷丝板可以自行清洗干净。

4、三甘醇(TEG)清洗法:先将喷丝板置于含15~20%NaOH的沸腾溶液中,时间2~3小时,以清除板上的大部分聚合物。继而将板置于260~280℃的三甘醇溶液中,保持约12小时,然后冷却。冷却后的喷丝板还要通过碱液、清水、超声波清洗以及干燥等处理。本法的优点是操作温度不会过高,能适合各种不锈钢喷丝板的清洗。缺点是清洗时间较长。

5、真空清洗法:在低压真空中灼烧,能使多种化纤聚合物发生分解,残留物在同一炉中被水冲刷干净,能自动控制,操作方便。
