Problems solved by technology

For the existing automobile glass, when the automobile glass is in humid air or cold environment, because the temperature inside the car is higher than the temperature outside the car, the water vapor in the air condenses on the surface of the glass to form fog droplets, affecting the line of sight
There is a fan on the car, which can blow air to the windshield, and accelerate the air flow to facilitate the evaporation of water mist, but its effect is not good, and it cannot completely remove the fog
At present, it is generally used to coat the glass with an anti-fog agent composed of a surfactant to solve this problem, but its operation is cumbersome, so it is very necessary to develop a tempered glass that itself has anti-fog function

Abstract

The invention discloses a manufacturing method of glass for sightseeing trains. The manufacturing method includes the following steps: (1), polishing edges of glass after cutting the glass; (2), washing the glass until the surface of the glass is free from dirt and water spots; (3), tempering the glass. The manufacturing method has the advantages that the glass is preheated before tempering, soaked in glycerite, and soaked in antifogging liquid after tempering, so that the tempered glass has an antifogging function and is suitable for the trains. The manufacturing method has the advantages that the antifogging liquid is safe and poisonless and has good antifogging effect and high adhesion force, poly-propoxy butyl ether sodium sulfate, sodium carboxymethyl cellulose and silicone oil have good antifogging functions, and polyphenylene ethylene, triethanolamine and silane coupling agents provide adhesion force to the antifogging liquid.

Description

technical field [0001] The invention relates to a method for preparing glass for a sightseeing train, belonging to the technical field of glass processing. Background technique [0002] Tempered glass is widely used in automobile, construction and other industries due to its advantages such as high mechanical strength, excellent temperature resistance and good safety. For the existing automobile glass, when the automobile glass is in humid air or cold environment, because the temperature inside the car is higher than the temperature outside the car, the water vapor in the air condenses on the surface of the glass to form fog droplets, affecting the line of sight. There is a fan on the car, which can blow air to the windshield, and accelerate the air flow to facilitate the evaporation of water mist, but its effect is not good, and it cannot completely demist. At present, it is generally used to coat the glass with an anti-fog agent composed of a surfactant to solve this prob...
