How To Distinguish True And False Acetate Optical Glasses ?
Actually Acetate is not a kind of material, however material form, steel acetatte, iron acetate, aluminum acetate, board, plastic board can call Acetate.
In the glasses frame, the acetate is different from other plastic material frame in the production process.Acetate frame is more common with acetic acid fiber (some is propionic acid fiber) as the main component of the material, through the milling machine for car, milling groove, car, car milling patterns, finalization, polishing, surface treatment, printing and other more than 100 processes from the production process is complex, high cost.
Methods
Acetate glasses is 100% uv resistance and density generally higher than injection frame, so relatively heavier more durable not easy to fade, and because the sheet is first formed, not only has a heavy and metal texture, can also produce all kinds of decorative pattern and color, than the monochrome injection frame are more likely to deduce the fashion style, popular people's favorite.In our daily selection, we can identify the Acetate frame through the following aspects.
1. Usually, the injection molding frame will produce obvious line traces at the joint gap of the mold, commonly known as the dividing line, which is generally in the edge center of the mirror and the mirror leg.Acetate do not
2. The nose rest of the acetate lens frame is transparent and colorless, no matter what color the frame is, the nose rest of the acetate lens frame is transparent, while the imitation of the injection molding lens frame is colored or opaque because it is made of one material.3. The gloss of the acetate eyeglasses frame is very good and soft.Imitate acetate glasses wear gloss all right, but luminous is different (hair thief light).
4. There is a metal wire inside the glass leg of the transparent acetate frame, while there is no metal wire in the imitation acetate frame.
