Protective glasses and protective masks are a type of personal protective equipment.
Protective glasses and protective masks are a type of personal protective equipment, mainly to protect eyes and face from dust, smoke, metal and sand debris and chemical solution sputtering damage, some special protective glasses or mask It can also prevent the radiation of electromagnetic waves such as ultraviolet, infrared and microwave to the human face.
So in different positions, what kind of protective equipment should we choose? Should we choose small and portable protective glasses or a protective mask with a higher safety factor and a larger protective area? Today, China tools manufacturer introduces the difference between protective glasses and protective masks for you to understand in more detail.
Medical Safety Googles
Classification of protective glasses:
Protective glasses are usually made of flexible plastic and rubber, and the frame is wide enough to cover the user's eyes. Protective glasses are mainly divided into three categories: anti-solid dust impact, anti-liquid splash, and anti-radiation.
1. Protective glasses against solid debris mainly used to prevent mechanical damage to eyes caused by metal or sand debris. The spectacle lens and spectacle frame should be strong and resistant to shock. There are edging around the frame, and there should be ventilation holes on it. The protective lens can be toughened glass, colloidal bonded glass or copper wire mesh protective glasses.
2. Medical safety goggles is mainly used to prevent chemical damage to eyes caused by irritating or corrosive solutions. Ordinary flat lenses can be used, and the frame should be covered to prevent the splashing of the solution.
3. Anti-radiation protective glasses used to protect the eyes from excessive ultraviolet rays and other radiation. The lens is made of special glass that can reflect or absorb radiation but can transmit certain visible light. The lenses are coated with bright chromium, nickel, mercury or silver metal film, which can reflect radiation; blue lenses absorb infrared rays, yellow-green lenses absorb both ultraviolet and infrared rays, and colorless lead lenses absorb X-rays and gamma rays.
Types of protective masks:
A mask that prevents splashes of dust and chemical solutions from splashing into the eyes and damaging the face. It is made of light transparent plastic and is made of polycarbonate and other plastics. It can cover the face more comprehensively to enhance the protective effect.
In addition to the aluminum foil mask mentioned in the thermal protective clothing, the heat-proof mask can also be made of a single-layer or double-layer metal mesh. If it can be plated with chrome or nickel, it can enhance the reflection and heat prevention effect and can prevent rust.
Metal mesh masks also protect against microwave radiation.
The face mask for electric welders is made of hard paper fiber with a certain thickness. It is lightweight, heat-proof, and has a good electrical insulating face mask. The biggest difference between protective glasses and protective screens is that protective glasses can only protect the eyes, and protective masks can protect the entire head of the human body.
Tools are probably as old as mankind itself. Humans have always made and utilized a variety of assistive devices and used them for their own purposes, which is considered to be the biggest difference between us and other species. How did the first tool come about?view more >
