Titanium metal has excellent characteristics, known as the "space metal", is the "third metal" after aluminum, is the most promising metal, it is light, corrosion resistance, allergy resistance, fatigue resistance and high strength advantages. Titanium metal, as a new type of glasses material, has been favored by more and more manufacturers since its introduction.
With its advantages of light weight, corrosion resistance, allergy resistance and high fatigue resistance, titanium metal has been used as a new type of glasses since its introduction. It is favored by more and more manufacturers. With the development of titanium materials and the increasingly naive processing technology, the market has appeared pure titanium, B titanium, memory titanium and many other titanium metal based titanium plate. Among them, pure titanium material of titanium plate purity requirements to achieve 99.9% without gaskets, screws, stipules and leg cover) its full label is called Puretita Nium or abbreviated as Ti-P, etc.. But individual manufacturer under the interest of some non pure titanium or titanium alloy materials are also more than the logo, plus some glasses dealers and consumers lack of identification ability of pure titanium, titanium plate, titanium plate after causing consumer wear titanium frame the phenomenon such as rust, skin allergies, harm the interests of glasses dealers and consumers. The following are some simple and easy methods to identify pure titanium plate.
Identification of titanium rod and titanium wire is the most commonly used is the most easy to think of, is to use a magnet to attract, with a magnet to do magnetic reaction will be as loose as possible titanium plate hinge. If the mirror leg swings under the attraction of the magnet, it means that the titanium plate is not pure titanium material, otherwise, it means that the titanium plate may be titanium. To sum up, it is not enough to simply judge whether the titanium plate material is pure titanium from the label, but also combine the above several methods for comprehensive evaluation, so as to identify the authenticity of the titanium plate. Two thin spacers are usually inserted into the hinge of a pure titanium mirror to separate the upper and lower hinges. Therefore, checking whether there is a gasket at the hinge is also a good way to identify whether it is pure titanium plate. Looking at the hinge joint from the inside of the titanium plate, a small groove will be found, which is specially designed to facilitate the removal of the gasket.
It's lighter by hand. This is one of the easiest ways to distinguish between titanium and non-titanium racks. By hand weight usually alloy frame specific gravity is about 8.9g/cm3 pure titanium frame specific gravity is 4.5g/cm3, because the weight of titanium material is equivalent to half of the alloy frame. The solder mark is "step" shape; The welding of alloy data was spot welding, and the welding points of nose stem and nose bracket were observed. The welding of pure titanium material was anaerobic bump welding. The welds are sloping, which is one of the effective ways to distinguish titanium and non-titanium, all titanium and non-all titanium. If there is pure titanium gasket in the hinge part should not be titanium and titanium direct contact, observe the joint, otherwise easy to appear at the joint wrinkle, the mirror leg is not smooth.
