What is the welding gradient protective glasses

Enterprises with complicated production conditions and many hidden safety hazards or occupational hazards should pay more attention to the management of personal protective equipment. The correct use of protective glasses can provide maximum protection for employees 'work, and is the basic guarantee for employees' health and life safety. So, what are welding gradient protective glasses? Electric welding gradient color protective glasses: Gradient color protective glasses are made by adding silver halide to the lens, which decomposes when exposed to ultraviolet rays, blocks the passage of light, and is synthesized without ultraviolet rays. There are two types, one is to sit the color-changing material directly into the lens material, called base change, and the other is to apply a color-changing film layer on the lens surface, called film change. Risk factors for eyes: 1. Shock. In all eye injury accidents, the eye injury rate caused by foreign objects such as debris or debris exceeds 70%. Many industrial sites involve mechanical operations, such as cutting, grinding, polishing, drilling, and machine tool operations. All of these operations may generate splash particles, and some have high speed and energy. Once these splash debris hit the eyes and faces, they may cause scratches, bruises, or more serious punctures. 2. Dust or smoke. Exposure to dust or smoke will cause discomfort to the eyes and even directly damage the eyes. Even small, low-energy particles can cause serious consequences when they enter the eye. For example, small metal particles or fiber particles can attach to the conjunctiva or cornea, and people can rub the eyes because of eye discomfort, which can increase conjunctival or corneal damage. Some fine particles may be dissolved by the liquid in our eyes and absorbed by the human body to cause other hazards, such as lead dust or other metal grinding dust. A large amount of dust can be carried into the eye by the eyelid, causing irritation or blurred vision and an additional risk of accidents. 3. Chemicals, chemicals are another major hazard. According to statistics from the US Department of Labor in 2009, injuries caused by chemical exposure accounted for 1/5 of the total reported eye-face injuries. Liquid splashing or splashing is the most common example of eye and face burns. There are also cases of eye damage caused by chemical gases or mist drops; harmful gases or vapors, such as chlorine, can cause eye irritation and even acute conjunctivitis. 4. Optical radiation, such hazards (including ultraviolet, strong visible and infrared) are exposed to almost every day in most industrial fields. For example, metal casting, glass manufacturing, and welding will produce a lot of infrared and ultraviolet radiation. For employees who often work outdoors, long-term exposure to sunlight can also cause irreversible eye damage. Different types and doses of radiation exposure can cause different parts and different degrees of damage to our eyes. 5. Thermal radiation, when working in furnace observation, metal casting, glass enamel processing or similar positions, may be injured by large thermal radiation, and may even be exposed to molten metal splash hazards. Thermal radiation may cause direct external burns to the eyes and face.
