Acetic acid board manufacturers: The difference between acetic acid board and celluloid.

Currently, handmade prescription glasses frames, sunglasses frames, and tinted glasses frames are mainly made of two materials, one isCelluloid, and the other is acetate sheet.

So far,Celluloidit has been invented for more than 150 years. Due to its texture, ductility, comfort, and unique aroma, it is often used as one of the materials for making prescription glasses frames, sunglasses frames, and tinted glasses frames.
It is much better than glasses frame materials. The most prominent disadvantage is that it is flammable and has long been unsuitable for large-scale, industrial, and mechanized production requirements. Therefore, currently, only a few pure handmade eyewear workshops are in production.Acetate sheetis different in that almost most European and American countries are usingAcetate sheetglasses frames.
There are many reasons for not usingCelluloid:
1.CelluloidIt is not corrosion-resistant. There is no basis for the corrosion caused by human sweat and cosmetics. This corrosion issue can be greatly alleviated by rinsing with water daily. If you are too lazy to wash, you can also polish off the corroded parts.
2. The lower ignition point is specifically designated for fire sources, and using high-speed rotating drill bits, cutting tools, etc., can only lead to "accidental smoking" when in prolonged contact with cigarette butts. Therefore, as long as you wear it, you don't have to worry about open flames. 3.CelluloidIt has a good texture (not only surface smoothness), good flexibility, high ductility (large adjustment range, more fitting to the skin), better touch and durability than metal sheets. The downside is that production batches are limited, labor costs are high, and prices are high.
4. In terms of wearing experience, if you pursue the chunky style of black frames, you must endure a relatively heavy weight. Some styles of metal glasses frames have bothCelluloidtexture and a lightweight feel, but whether they meet the aesthetic requirements of customers is a question. Another reason is that the frames sold in stores have not been adjusted in size, and you need a professional to adjust them with a heating lamp to achieve the most comfortable wearing experience. Usually, this debugging process takes about 20 minutes.
