Advantages of metal spectacle frame

Advantages: it has certain hardness, good flexibility, good elasticity, wear resistance, corrosion resistance, light weight, luster and good color.

1, high nickel alloy frame: the nickel content is as high as 80% or more, mainly including nickel-chromium alloy, manganese-nickel alloy and so on. High nickel alloy has better corrosion resistance and good material elasticity.

2. Monel frame: Nickel-copper alloy, with nickel content of about 63% and copper content of about 28%. In addition, there are other small amounts of metals such as iron and manganese, especially corrosion resistance, high strength and firm welding, which are the most widely used materials for mid-range frames.

3. Memory titanium alloy mirror frame: It refers to a new alloy composed of nickel and titanium in the atomic ratio of 1: 1, which is 25% lighter than the general alloy, has the same corrosion resistance as titanium and excellent elasticity. Memory titanium alloy: shows shape memory below 0℃ and high elasticity between 0-40℃. The corrosion resistance of memory titanium is higher than Monel alloy and high nickel alloy, but slightly lower than pure titanium and β -titanium

4. Gold-plated frame: This process is to add solder or direct mechanical bonding between the surface metal and the substrate. Compared with electroplating, the metal layer on the surface of the coating material is thicker, which also has a bright appearance and good durability and corrosion resistance. Indication of Jinbao: According to the regulations of the International Precious Metals Conference, products with the weight ratio of gold to alloy above 1/20 are denoted by GF, and products below 1/20 are denoted by GP.

Cleaning and maintenance

1, ultrasonic cleaning, vibration to remove the dirt inside, the general optical shop has this service, basically free.

2. The lens groove of Quan Huafu spectacle frame is dirty. You can unscrew the screw yourself, take off the lens and clean it with a paper towel.

3. If the screw is loose, please take it to the optical shop and tighten it in time, otherwise the lens will easily fall to the ground and break. Don't handle it at will

4. Cosmetics containing chemical components, such as cosmetics or beauty agents, are easy to fade glasses frames. Please clean it with a special cloth or paper for glasses.

Most glasses are gently folded from the left temple first. If folded from the right, the frame itself will be unbalanced and skewed, and it will be very uncomfortable after wearing it.

6. In order to give full play to the correct function of glasses, the optical center of the lens is suitable for your eyes, so please wear it in the right position.

7. Wearing glasses with one hand is easy to deform the frame. If the frame is deformed, you should find a local optician to adjust the angle, and don't do it yourself, so as not to break the lens and damage the frame.

8. Don't put it in a place where the sun is easy to expose for a long time, because the frame is easy to fade and pyrolyze under light. Especially the frame, please don't put it on the dashboard when driving.

9. Dry with a special cloth for glasses. Don't touch the lens with hard objects. Don't rub your fingers against the lens. Please wipe the lens with a clean lens cloth to reduce lens wear.

10, don't put down the convex surface of the lens. When not in use, try to put your glasses in the eye box. When not in use, please wrap the glasses with mirror cloth and put them in the mirror box to avoid damage.

1 1. Please put the baby next to you to rest.
