What Materials Are Often Used in Sunglasses Frames?
When summer comes, of course, you have to wear a pair of beautiful sunglasses when you go out! It can not only be used as decorations to improve the appearance, but also block harmful light such as ultraviolet rays, reduce glare, and effectively protect the eyes from damage. It is really a necessary good product for travel. I believe that many people now have a pair of sunglasses. Do you know what materials are often used in your sunglasses frame?
1. Cellulose propionate: CP material for short, with appropriate elasticity and toughness; It can be dissolved in solvent to form a shape, so the material should avoid contact with acetone, banana water and other organic solvents; CP material is not easy to oxidize, decompose, age and burn in the atmosphere, and its plasticity and fluidity are good. Therefore, there are various processing and coloring methods, which can make rich and varied colors. Based on the stability of CP material.
2. Polycarbonate: PC material for short, with a specific gravity of 1.2, non combustion supporting, odorless and non-toxic resin, which conforms to the regulations of FDA and the U.S. drug administration, and its characteristics are the same as those of PC lens.
3. Epoxy resin: also known as EP plastic, it has good temperature resistance and is 30% lighter than ordinary plastic. It has high strength, high hardness and good elasticity. It can be made into thin and light spectacle frames. At the same time, it has special memory function, so it is also called memory plastic, which is often used to make advanced mirror frames, mirror feet, etc.
4. Manganese nickel alloy: it is an alloy with manganese and nickel as the main alloy elements. Manganese nickel alloy has good mechanical strength and corrosion resistance.
5. TR-90 material (super tough memory resin material imported from Switzerland): Super Tough: prevent the frame from deformation or even fracture during movement, and protect the face from injury. Memory function: special memory function, with anti deformation index of 620kg/cm2. Light weight: tr-90, which is 30% lighter than the plate, can effectively reduce the weight of glasses and make them more comfortable to wear. Impact resistance: it can effectively resist the impact of external forces, which is more than two parts of the plate.
6. Aluminum magnesium alloy material: light, environmentally friendly and durable. This material is now widely used in high-tech products such as mobile phones and laptops.
7. Titanium material: during the heating process of titanium metal, when the temperature exceeds 860 ℃, its molecular structure will change and form β Titanium. β The density structure of titanium is better than that of titanium, so its elasticity is better than that of titanium, and its price is three times that of titanium! Because its hardness is higher than that of titanium, it is more difficult and cumbersome than titanium in the process of technical processing.
