They are loved by more young people because of their strong ability to follow trends. Today Yichao will take everyone to take a look at the advantages and disadvantages of sheet glasses frames. Nowadays, most of the material of the sheet frame is made of high-tech plastic memory sheet, the composition of the sheet is mostly acetate fiber, and a few high-end frames are made of propionic acid fiber. The acetate sheet is divided into injection molding type and pressing and polishing type. The injection molding type, as the name suggests, is made by pouring in a mold, but currently most of them are pressed and polished plate glasses. The characteristics of the plate mirror frame are as follows: not easy to burn; strong and durable; good gloss, beautiful style, not easy to deform after wearing; baking processing temperature should not exceed 130 degrees, if the temperature is too high, it will foam; it is less prone to allergies. The sheet glasses frame is light in weight, strong in hardness, and good in gloss. The combination with the steel skin strengthens the firmness, and the style is beautiful, it is not easy to be deformed and discolored, and it is durable. It has a certain degree of elasticity, and the shape memory board will return to its original shape when it is bent or stretched a little harder and then relaxed. The plate mirror frame is not easy to burn, hardly discolors under ultraviolet radiation, has a larger hardness and better gloss, is not easy to heat processing, has a more beautiful style, and is not easy to deform after wearing. The plate frame is also suitable for people with a high number of heights, because the frame is larger and can withstand a high number of lenses. At the same time, the plate glasses frame is easier to match with the clothing, combining the thickness of the plate and the metal texture, the perfect integration of the temples and the foot covers, it seems to be natural, and the lens shape is extremely personalized. The frame shape has both modern and classic features, with streamlined and rich-color spliced borders, perfect for seamless integration. So what are the disadvantages of sheet glasses frames? In fact, the shortcomings of sheet metal spectacle frames are not very obvious, but compared with metal and titanium spectacle frames, sheet metal spectacle frames are easily deformed when they are removed with one hand for a long time. Advantages of metal spectacle frames Advantages: a certain degree of hardness, good flexibility, good elasticity, wear resistance, corrosion resistance, light weight, luster and good color. 1. High-nickel alloy frames: The nickel content is as high as 80%, mainly nickel-chromium alloys, manganese-nickel alloys, etc., high-nickel alloys have better corrosion resistance, and in addition, the material has good elasticity. 2. Monel frame: nickel-copper alloy, with a nickel content of about 63%, copper and 28%, in addition to iron, manganese and other small amounts of metals, especially: corrosion resistance, high strength, strong welding, used for mid-range frames The most material. 3. Memory titanium alloy frame: refers to a new alloy composed of nickel and titanium at an atomic ratio of 1:1. It is 25% lighter than ordinary alloys and has the same corrosion resistance as titanium. In addition, it has very good elasticity. Memory titanium alloy: It has the characteristics of shape memory below 0℃, and high elasticity between 0-40℃. The corrosion resistance of memory titanium is higher than that of Monel and high-nickel alloys, but it is better than pure titanium and β -Titanium is inferior. 4. Gold-clad frame: The process is to add solder or direct mechanical bonding between the surface metal and the substrate. Compared with electroplating, the surface metal layer of the cladding material is thicker, and it also has a bright appearance, good durability and good durability. Corrosion resistance. The indication of the gold-clad number: According to the regulations of the International Precious Metals Conference, products with a weight ratio of more than 1/20 of gold to alloy are indicated by GF, and products below 1/20 by weight are indicated by GP.
