供应长效夜光粉、长效夜光油墨、温变油墨、光变油墨、香味油墨
本公司生产的发光颜料,可以和多种透明调墨油结合在一起制成发光油墨,赋予油漆在夜暗处发光功能。在亮处吸光10-30分钟后,可在暗处发光12小时以上,其吸光发光功能无限循环使用。
发光油墨是由发光颜料、有机树脂、有机溶剂、助剂通过一些工艺制成。每一种组份决定着发光油墨的性能,其选择标准很重要。我
发光油墨配制
1、树脂的选择:
发光油墨印刷后,发光吸光功能由发光颜料的颗粒来实现的。由于光线通过的要求,将发光颜料粘接在一起的树脂应该有较好的透光性,无遮盖力。选择原则为无色或浅色透明度好。由于丝网印刷油墨品种繁多,建议根据需要印刷的底材来选择油墨的品种,如在PVC塑料上印刷选择用于PVC的调墨油,金属底板就选择金属油墨,纸张上印刷可以选择纸张油墨等等。
2、发光颜料的选择:
由于印刷品表面状况及丝网透过率要求,由于配制丝网印刷油墨选择粒径较小的发光颜料。如YA型、YB型、YC型、发光颜料粒径越大,表面越粗糙。
3、发光颜料的用量:
发光颜料的用量:一般为总量的30-50%,根据印刷品的亮度要求确定发光颜料的用量。油墨中的含量越高,用它印刷的制品发光亮度越高,发光时间越长。
4、配制工艺:
a)容器的选择:选择玻璃、陶瓷、搪瓷内衬、塑料容器。
b)制作工艺:发光颜料不能研磨,不能使用三辊研磨机配制发光油墨,只能使用高速分散机或搅拌机配制发光油墨。用手工方法也可以将发光颜料分散在油墨中。具体方法将树脂或清漆放入容器中,加入助剂,开动搅拌,在搅拌状态下依次加入防沉剂、发光颜料(注意此时转速较慢)。加完发光颜料后提
The illuminating pigment from the company can be mixed with several transparent inks into illuminating ink, which enables the paints to be able to emit light in darkness. It has a strong light-absorb capacity.
Illuminating ink is made from illuminating pigment, organic resin, organic solution.
Formula of Illuminating Ink
1. Select Resin
After the illuminating is put into use, the light emitting/ absorbing functions will be activated by pellets of the pigment. So preferably the resin should be colorless or transparent.
2. Select Illuminating Pigment
Select pigment according to the size of the silk screen mesh. The larger the pellets of the pigments are, the coarser the surface become.
3. Dosage of Illuminating Pigment
Dosage generally should be 30%-50%. The dosage should be determined to the requirement for the brightness of the presswork.
4. Concocting Technics:
a) Select Receptacle: Glassware, pottery, interlining of enamel, plastic recepticle.
b) Technics of Crafts: Preferably use the high-speed mixer to formulate illuminating ink. The procedure is: put resin inside receptacle and add agent before stirring. Then add in sequence the sediment-free agent, illuminating pigment and begin to increase spinning pace.
