Disposable toothbrush is an essential part of hotel supplies. How to purchase disposable toothbrush? Maybe a lot of friends don't understand. Now AI Xiao's class is open. Let's learn about it with you.
1. Toothbrush material
Toothbrush materials are mainly divided into soft plastic and hard plastic, so how to distinguish the two materials? A toothbrush can be thrown on the ground in a free falling way. If the toothbrush falls on the ground with a clear sound and a high rebound height, the material of the toothbrush handle is hard plastic; on the contrary, if a toothbrush does not rebound after landing and there is no crisp ground throwing sound, then the toothbrush is soft plastic. In addition, the toothbrush of the same style and specification is easier to break than the soft plastic one.
Is there any difference in quality between soft plastic and hard plastic toothbrushes?
The two materials are derived to meet the market needs of different styles of combs. Only fixed raw materials can be used for specific styles, and there is no difference in quality between the two materials. For example, if you want to make a two-color or transparent toothbrush, you must use hard plastic. There is no other reason. This is the production process of the product. Or if you want to make a toothbrush with translucent effect, you have to choose soft plastic raw materials.
2. Toothbrush bristles

2. The second method is the feel of the toothbrush bristles. Of course, the best thing is to try a toothbrush with different bristles.
