Glasses with titanium plate, referred to as glasses board, is made of titanium material processing plate, divided into pure titanium glasses board. Titanium glasses, memory titanium glasses board.
Titanium has good corrosion resistance, similar to platinum, its excellent mechanical properties. Used in the frames is to adopt its light, flexible, corrosion-resistant and so on.
However, titanium and titanium alloy production costs are high, in the buckling, stamping, cutting and welding requirements are prohibitive, easy welding and plating, welding must be completed in a vacuum. So the price is more expensive, only for high-end glasses frame.
Titanium metal as a new type of glass since its inception, with its light, corrosion resistance, anti-allergy, high strength, is more and more consumers are favored. With the development of titanium materials and processing technology is increasingly mature, the market has appeared in unalloyed titanium, B titanium, memory titanium and other titanium-based frame. Among them, pure titanium frame material purity requirements of 99.9% (excluding gaskets, screws, stipules and leg sets), the logo called PURETITANIUM, or abbreviated as Ti-P and so on. But the individual manufacturers in the interests of some non-titanium or titanium alloy material also carried out the above logo, coupled with the vast number of consumers on the pure titanium frame identification capacity, resulting in consumers wearing titanium frame after the emergence of frames Rust, skin allergies and other phenomena, damage the interests of the vast number of consumers. Here are some simple methods to identify pure titanium frames.
1. The weight of the hand, usually the proportion of alloy frame is about 8.9g / cm3, the proportion of pure titanium frame is about 4.5g / cm3, because the weight of titanium material equivalent to half of the alloy frame, hand up relatively light. This constitutes one of the simplest ways to distinguish titanium frames from non-titanium frames.
2. To observe the welding point of the nasal stem and the nasal care of the care, pure titanium material welding for the vacuum anaerobic welding, where the weld is "step" shape, the welding of alloy materials for spot welding, This is one of the effective ways to distinguish between titanium and non-titanium.
3. Observe whether the hinge joints with gasket, titanium frame in the hinge site should be not in direct contact with titanium and titanium, or prone to joints at the wrinkle, the temples closed with the phenomenon of poor. Usually in the titanium frame hinge parts inlaid with two thin gaskets, the upper and lower hinges separated. Therefore, check the hinge with or without gasket, but also to identify whether the pure titanium frame is an effective way.
4. With the magnet to do the magnetic reaction, the frame hinge as far as possible loose, in the free state to use the magnet to attract, such as the mirror in the magnet under the attraction of the rock, indicating that the frame is not pure titanium material, Shelf may be pure titanium frame.
Glasses and titanium plate is divided into three categories, pure titanium; TC4; and B titanium 15333, pure titanium and soft board and hard board, the general soft board than the hard board slightly expensive, soft board general Requirements of the hardness of the 67 - 80; can be stamping, hard board generally require hardness of the network of 90-97; can not be stamping, only wire cutting. High-end glasses with 15333 titanium materials flexible processing difficult.
Β titanium used as spectacle frames and glasses frame advantages:
Β titanium alloy is titanium in the zero-point state of the delay time to complete the completion of beta particles of titanium material, the processing technology is higher than pure titanium, it has better than pure titanium and other titanium alloy strength, anti-fatigue properties and resistance to the environment Corrosion performance, good shape plasticity, solid state, its elastic modulus is low about 80GPa, slightly higher than the titanium nickel shape memory alloy elastic modulus (60 GPa or so), it has a high elasticity of restoring force (ie Arch wire after a long distance bending without permanent deformation), low hardness, easy to shape, can bend or form a complex shape, without being broken. With its manufacturing glasses frame to make up for the pure titanium frame mirror leg elasticity, good elasticity and memory characteristics, and β titanium alloy processing performance and excellent welding, made with its spectacle frame shape and style is more A new generation of glasses production materials. Therefore, β titanium alloy frames in Europe and the United States and other developed and are as a high-end decorations and a popular fashion. It has been extensively used in high-grade titanium glasses frame wire and foot wire production.
