These problems are directly related to the selection of acrylic materials. In this paper, we will introduce several methods to judge the quality of acrylic cream bottle, so as to distinguish them in the future.
The first observation method: This is a method based on the material characteristics of acrylic. We can see whether the acrylic board is slightly discolored or not glossy when purchasing acrylic. If it exists, it indicates that the quality of acrylic is not good. In addition to this observation method, you can also see whether the manual of acrylic is consistent with the actual situation of acrylic plate. If not, you can also judge whether the acrylic material is not normal.
The second method of combustion: a very small piece of acrylic can be used for combustion test. If the acrylic plate burns quickly, the quality of acrylic is not good.
The third light transmission method: this method is derived from the characteristics of acrylic light transmittance. It can send positive white light through the acrylic plate through the light. If yellow or blue color is found, it indicates that the quality of acrylic is not good, because the transmittance of acrylic plate is very high, and the light after transmission belongs to positive white light and will not absorb light color.
The fourth method of sticking: this method is also called hot-melt method, it is the use of good acrylic materials and bad acrylic materials of different degrees of adhesion and distinction. For example, poor quality acrylic materials will stick together after hot-melt and difficult to separate, good quality acrylic is easy to separate.
The fifth packaging method: good quality acrylic material soft rubber edge packaging is very good, bad acrylic board soft rubber edge looks very mixed, this industry is called joint venture board. Of course, the good packaging of acrylic plate in the price is certainly worse than a little more expensive acrylic.
In the production of acrylic cream bottles, we use these identification methods to ensure the quality of our raw materials. They are also the five methods to identify the quality of acrylic plates summed up in practice for many years. At the same time, we hope to be corrected and supplemented by peers or experts.
