Anti-fog spray can be sprayed on the protective mask for anti-fog treatment. It is available online and in optical stores and is very effective.
The main reason for the fogging of the protective visor is that the warm gas in the eye area of ??the gas mask condenses on the relatively cold lens surface. In actual operations, the visor fogs up. It will cause inconvenience to workers.
To this end, scientists have studied anti-fog technologies for various lenses to prevent the visor from fogging.
1. Structural lenses are anti-fog, which can eliminate water vapor condensation conditions. The temperature of the inner surface of the lens will not be lower than the dew point temperature of water vapor condensation in the screen or window, including controlling the temperature of the inner surface of the lens.
2. Physical-chemical lens anti-fog technology inhibits the formation of water mist, that is, the use of hydrophilic or hydrophobic chemicals to inhibit the formation of mist droplets from water vapor. The reason why the visor of Dinghe DH20154 gas mask is anti-fog is because there is an anti-fog coating on the polycarbonate visor, and this anti-fog technology is applied.
3. The artificial lens anti-fog method removes the formed fog and directly wipes the water vapor droplets on the lens through manual intervention. With the continuous development and application of gas masks in our country, higher requirements have been put forward for the anti-fog technology of gas masks, and comprehensive anti-fog technology has gradually become the mainstream development trend.
