| 2018年早已起航，一切都步入了正规，工厂也陆续开业了，很多老板都准备大干一场，都想着把自己的产品提升一个档次，外观的亮度一直是客户要求的硬性条件，外观的亮度好坏也决定了颗粒价格的高低。但是真正找到适合塑料的増亮产品不是件容易的事，作为生产的工厂要考虑塑料的相溶性，五大塑料的特性不一样，内部分子结构不一样，用的増亮产品也是不一样的，就举个简单的例子PE高压塑料造粒来说，PE高压塑料造粒比较广泛，大多分为一级和二级，有的厂家用的是一级料，也有的厂家想降低成本选择二级料，可想而知二级料成产出来的产品亮度会差一点，怎么才能达到一级料的亮度。塑料助剂专家建议添加光亮剂，有很多厂家选择比较低端的光亮剂，低端的添加量比较大，从成本上也是增加了不少，还有一个缺陷就是和PE塑料相溶性差，在热熔的时候光亮剂都是浮在表面，冷却之后也是一样，表现出来的现象就是手指一划会出现白痕，给用户造成很大的困扰。通过很多厂家的反馈回来的结果是二级料生产的时候添加升级版粉末可以达到一级料的效果，有的可以达到全新料的效果。用在造粒上效果比较好，操作简单，不改变生产工艺，和原材料均匀搅拌就可以，为了防止光亮剂沉底，可以适当的配合一点工业白油，这样分散效果好。在热熔条件下有很好的流动性，对色粉也有很好的流动性，亮度可以提升两倍以上，出来的产品亮度像镜子一样。 In 2018, everything has already set sail, factories have opened, many bosses are ready to do a big job, all want to upgrade their products, the brightness of the appearance has been the customer requirements of the hard conditions, the brightness of the appearance also determines the level of particle prices. But it's not easy to find the brightening products suitable for plastics. As a manufacturer, the solubility of plastics should be considered. The five plastics have different characteristics, different internal molecular structure and different brightening products. For example, the granulation ratio of PE high-pressure plastics is a simple example. More widely, mostly divided into first and second-class, some manufacturers are using first-class materials, some manufacturers want to reduce costs and choose second-class materials, can imagine that the brightness of the products produced by the second-class materials will be a little worse, how to achieve the brightness of the first-class materials. Plastic additives experts suggest to add brighteners, many manufacturers choose a lower-end brightener, low-end addition is larger, from the cost is also increased a lot, there is a defect is poor compatibility with PE plastics, in hot melt brighteners are floating on the surface, cooling after the same performance, showed Image is a white mark on a finger, causing great trouble to users. Feedback from many manufacturers has resulted in the addition of upgraded powders in the production of secondary materials can achieve the effect of primary materials, and some can achieve the effect of new materials. It can be used in granulation with good effect, simple operation, no change in production process, and even stirring of raw materials. In order to prevent the brightener from sinking, it can be appropriate with a little industrial white oil, so that the dispersion effect is good. It has good fluidity under hot melt condition, and also has good fluidity to the color powder. The brightness can be increased more than twice. The brightness of the product is like a mirror. |
