荧光增白剂在塑料中的运用
Application of Fluorescent Whitener in Plastics
许多塑料终端消费厂家关于如何正确的运用 普通来说荧光增白剂在塑料中的运用办法有三种,辨别爲:干法增白、湿法增白和色母粒增白.接上去,小编就详细的爲大家引见下三种工艺的不同,以及试用的终端产品.
Many plastic terminal manufacturers have three ways to use fluorescent whitening agents in plastics: dry whitening, wet whitening and color masterbatch whitening.

塑料干法增白就是将一定量的荧光增白剂干粉间接添加于成塑前的塑料基材中,先与塑料基材停止混合,待挤出机到达塑料镕融温度时,将混合料挤入螺杆熔融,以使荧光增白剂在熔体中平均散布,比较初停止造粒或压制成型.干法增白剂次要用于硬质聚录乙烯、聚乙烯、聚丙烯、ABS以及其他热塑性树脂的注塑成型增白.用于干法增白剂的荧光增白剂价钱绝对廉价,但是有粉尘飞散性大、净化环境的缺陷.
Plastic dry whitening is to indirectly add a certain amount of fluorescent whitening agent dry powder to the plastic base material before plasticizing. First, it stops mixing with the plastic base material. When the extruder reaches the melting temperature of the plastic picks, the mixture is extruded into the screw to melt, so that the fluorescent whitening agent is evenly dispersed in the melt. At first, it stops granulating or pressing. Dry whitening agent is mainly used in rigid polyethylene, polyethylene and polycondensation. Injection-moulding whitening of propylene, ABS and other thermoplastic resins. Fluorescent whitening agent for dry whitening agent is absolutely cheap, but it has the defects of large dust dispersion and environmental purification.

湿法增白爲了改善分散效果,有时还需求在荧光增白剂中参加一定量的粘合剂,使荧光增白剂较好地粘附于物料外表,以增加其粉尘飞扬和净化.也可以将荧光增白剂分散在助剂溶液中,以助剂分散体的方式分批参加,如用于软质聚录乙烯(PVC)中,可将其配成10%的邻苯二甲酸二辛酯增塑剂溶液后,再分批参加.在湿法增白中荧光增白剂呈纤细的分散状浆料,因有非灰发性无机溶剂混入增塑剂中,所以有发黏的缺陷.这种办法次要用于软质聚录乙烯增白.
In order to improve the dispersion effect of wet whitening, it is sometimes necessary to take part in a certain amount of adhesives in the fluorescent whitening agent, so that the fluorescent whitening agent can adhere to the surface of the material better to increase the dust flying and purification. It can also be dispersed in the additive solution and participated in batches in the form of additives dispersion. For example, when used in flexible polyethylene (PVC), it can be compounded into 10% phthalic acid. Dioctyl ester plasticizer solution, then participated in batches. In the wet whitening process, fluorescent whitening agent is a fine dispersed slurry, because there are non-gray inorganic solvents mixed into the plasticizer, so there are viscous defects. This method is mainly used for soft polyethylene whitening.

目前塑料运用"色母粒"已成爲塑料着色的中重要手腕.在运用色母粒时,只需将色母粒和树脂按比例混合平均,即可间接用来停止塑料制品的成型加工.大批的搅拌只需用手,在加工量较大的状况下,爲了保证色母粒的分散性,可以运用机械搅拌.色母粒与树脂塑料机械混合当前即可送到带预塑安装的注塑机,边预塑边着色.
At present, the application of colour masterbatch in plastics has become an important wrist in plastic colouring. When using colour masterbatch, only mixing the colour masterbatch and resin proportionally and evenly can indirectly be used to stop the forming of plastic products. Large quantities of mixing only need to be done by hand, and in the case of large amount of processing, in order to ensure the dispersion of colour masterbatch, mechanical mixing can be used. When colour masterbatch and resin plastic are mechanically mixed properly. It can be delivered to the injection moulding machine with pre-moulding installation, while pre-moulding and coloring.
