Introduction of carbon fiber as material in eyeframes

Carbon fiber is a kind of new materials of eyeframes, It has not only the inherent characteristics of carbon, but also has the soft and machinable of textile fibers. The carbon fiber is as the material for producing eyeframes and sunglasses, and these eyeframes has the soft and machinable of textile fiber. And carbon fiber is very resisting corrosion. After tested the carbon fiber eyeframes, they could keep its original shape perfectly in the kinds of badly environments, the feature is not available in metal also titanium eyeframes.Carbon fiber is a new material with excellent performance, and its weight is less than 1/4 of steel, its tensile strength is generally above 3500Mpa, and it is 7-9 times of steel.Therefore, the ratio of its strength and density can be up to 2000Mpa/(g/cm3), and the ratio of A3 steel is only about 59Mpa/(g/cm3). Many people expect that the application of materials will be from the steel age to the composite materials age which will be extensive used. Carbon f…

The aluminium eyeframes anodizing production process

The production process for aluminium eyeframes anodizing surface treatment mainly include these steps: cleaning, anodizing, dyeing, sealing, assembling, etc. After anodizing surface treatment, the aluminium eyeframes have beautiful and bright color; its corrosion resistance, wear resistance and insulation is better than other aluminum products. The aluminium eyeframes hanging in a specific electrolyte solution are used as an anode for electrolysis. During the electrolysis process, the hydroxide ions in the water emit electrons and turn into water and new ecological oxygen in anode, which oxidizes the aluminium into a thicker alumina film. This process is the oxidation of the metal product as an anode, so it is called anode Oxidation. By anodizing, dyeing and sealing treatment, the original aluminium eyeframes become dyed products. The first step for Aluminium eyeframes anodizing process : clean the aluminium eyeframes. During the manufacturing processing, Aluminium eyeframes stained w…
