What do you know about the characteristics and classifications of goggles?
2020-12-15
GogglesGoggles are a type of glasses used in special environments. Unlike ordinary glasses, goggles vary depending on the occasion. So what are the characteristics of goggles? What classifications do goggles have? Today, let's learn about them.
Characteristic 1: Strength. At room temperature, a steel ball weighing 45 grams must be able to fall freely from a height of 0.6 meters to the center of the lens without causing any damage.
Characteristic 2: Corrosion resistance. After soaking metal parts in boiling 10% sodium chloride solution for 15 minutes, immediately remove them, leave the remaining liquid on the parts, dry at room temperature for 24 hours, then rinse with warm water and dry. There should be no signs of corrosion on the surface.
Characteristic 3: Flame retardant. The plastic material should extinguish itself within 5 seconds after leaving the fire source.
Characteristic 4: In operations such as smelting, glass, ceramics, and mechanical heat treatment, production workers often come into contact with high-temperature furnaces and other heat sources, with temperatures generally between 1050-2150 degrees. At this temperature, 70% of infrared rays, visible light, and ultraviolet rays can be generated.
GogglesCan be used in furnaces, heating furnaces, high-temperature furnaces, and other workplaces where infrared is the main radiation source. The classifications are as follows:
Ordinary goggles: These furnace goggles have the same style as ordinary goggles.GogglesHowever, the lenses have the function of preventing infrared radiation.
Front suspension goggles: This product is installed at the back of the helmet and can be flipped. The lens can be lowered during use and raised when not in use.
End shading typeGoggles: Based on the ordinary type, shading plates are added to both sides of the frame, and then an anti-infrared filter is installed.
Open-type goggles: Composed of a single infrared filter, eye mask frame, and belt. The filter can be replaced as needed, and the upper part of the eye mask is open.
Closed typeGoggles: A single infrared filter fixed to the eye mask frame, which cannot be replaced at will, and the eye mask is completely closed. In addition, there is a portable fire mirror for observing the size of the flame in the furnace.
Wearing goggles can effectively avoid radiation damage to the eyes. The so-calledGogglesis a type of filter that can change the intensity and spectrum of transmitted light. This type of glass is divided into two types: absorption type and reflection type, with the former being commonly used. This glass can absorb certain wavelengths of light while allowing other wavelengths to pass through. Therefore, they all exhibit a certain color, which is the color of the transmitted light.
