How to distinguish the quality of acrylic lens raw materials

A good acrylic lens raw material directly determines a high-quality acrylic lens product. This is inevitable. If the acrylic lens raw material of inferior quality is selected, the acrylic lens product produced and processed will appear deformed, yellowed or blackened or produced. There are many defective products in the processed acrylic lens products. Such situations are directly related to the selection of acrylic lens raw materials. To this end, the editor of Acrylic Lens Processing will give you a detailed introduction to several types of methods for distinguishing the quality of acrylic lens raw materials for you to distinguish later.

1. Observation method:

This is a method to distinguish according to the material characteristics of the acrylic lens. When we buy acrylic lenses, we need to see if the acrylic lens plate will be slightly discolored or the brightness is not high. If it exists, it means that the quality of the acrylic lens is not very good it is good. In addition to this observation method, you can also see whether the specific instructions of the acrylic lens and the acrylic lens sheet are the same. If they are not the same, it can be distinguished that the raw material of the acrylic lens is not good.

2. Combustion method:

It is recommended to use a smaller piece of acrylic lens for the burning test. If the acrylic lens plate burns quickly, it indicates that the quality of the acrylic lens is not good.

3. Light transmission method:

This method is developed with the help of the light transmittance characteristics of acrylic lenses. It is recommended to use light to emit white light through acrylic lens plates. If you see yellow or yellowish colors, it means that the quality of acrylic lenses is not good. Because the acrylic lens sheet has a high light transmittance and the light after penetration is positive white light, and does not absorb colored light.

4. Paste method:

This method is also called the hot-melt method. This method is based on the difference between the adhesion of good acrylic lens raw materials and bad acrylic lens raw materials. For example, raw materials of poor quality acrylic lenses will stick together and cannot be separated after being melted, and good quality acrylic lenses are easy to separate.

V. Packaging method:

Acrylic lens materials with good quality are packed well with soft rubber edges. The soft rubber edges of acrylic lens plates that are not very good look too mixed in color. This manufacturing industry is called a joint venture plate. Of course, in addition to this point, the packaged good acrylic lens sheet is indeed more expensive than the slightly worse acrylic lens.
