荧光增白剂OB-1是一种白色粉末,主要由苯乙烯和聚乙烯醇组成,主要用于增白纤维素类纤维和染料染色纤维材料,它具有良好的耐水性、耐洗涤性和耐磨性等特性,可显著提高纤维织物的亮度和色泽,使其具有良好的服装性能。它具有优异的抗褪色性,并且具有良好的耐气候性和耐氧化性,可显著提高纤维的耐久性和使用寿命。此外,它还可以改善纤维的柔软性,使其具有更好的穿着舒适性。
Fluorescent whitening agent OB-1 is a white powder mainly composed of styrene and polyvinyl alcohol. It is mainly used for whitening cellulose fibers and dyeing dyeing fibers. It has good water resistance, washing fastness and abrasion resistance, which can significantly improve the brightness and color of the fiber fabrics and make them have good clothing performance. It has excellent anti-fading performance and good weatherability and oxidation resistance, which can significantly improve the durability and service life of the fibers. In addition, it can also improve the softness of the fibers, making them more comfortable to wear.
根据涂料的不同工艺,水性荧光增白剂的加入方法有三种:
1、荧光增白剂在色浆研磨工序(即色浆的制作准备工序)以粉状产品的加入,然后经过充分研磨直至微粒小于20um,并均匀分散到涂料中。
2、将荧光增白剂研磨细之后,经高速分散机加入涂料中。
3、在生产过程中,用30-40度左右的温水和CH₃CH₂OH混合液将荧光增白剂溶解,再加入水性涂料中,再经过充分搅拌分散均匀,添加量为涂料重0.02-0.05%。
水性荧光增白剂的注意事项:
1、在使用W和水性系列环保水性颜料前,需做混溶性实验;
2、不宜暴晒或接触雨水;
3、应保存在干燥的室内;
4、储存时间不宜过长,拆开包装使用后,应立即将其密封,防止氧化;
5、如放置时间过久,请在使用前检测;
6、使用时应缓速搅拌,过快的搅拌会破坏表面包覆物;
7、不慎起火时,切勿用水或二氧化碳,须用干沙或特别干粉灭火;
8、产品均为钢桶密封包装,便于运输及保存。
