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.
在聚合物中添加任何紫外线吸收剂时,应注意适当调整荧光增白剂OB的添加用量。具体可根据产品试验来调试。
有些增白剂的应用需要增白剂耐高温,所以需要了解增白剂的熔点。平时我们看到的户外广告、店面招牌等,大部分都是塑料制品。对于这种长期置于户外的塑料,为了保持其色彩的艳丽,荧光增白剂各型号粉体必须具有很高的耐候性,也是长期使用不易变色发黄。
许多荧光增白剂在一定的加工温度时会部分溶解在塑料中,此时荧光增白剂容易在这些底物中发生迁移。因此,荧光增白剂要具备优良的耐迁移性,不能迁移或渗透到其他材料中。
与其他添加剂的化学惰性且相容性要好。塑料在加工时,必然会加入许多添加剂,从而影响塑料增白剂的增白剂效果。如果两者要同时使用,应当考虑它们的匹配性。
