Problems solved by technology

However, due to the reflection of sunlight on the surface of the glass baffle, the light transmission efficiency of the reflected light of the solar mirror field array (primary reflector) into the secondary reflector will be reduced.
Moreover, the sunlight entering the secondary reflector has been concentrated by the primary reflector (condensation ratio: 10~50), so the reflection of the sunlight entering the secondary reflector on the surface of the glass substrate will significantly reduce the solar heat collection field. mirror field efficiency
Existing ultra-clear glass usually has low light transmittance, poor anti-reflection ability, and dust on the surface during specific use, especially in outdoor environments, which affects the normal use of the ultra-clear glass surface.

Abstract

The invention relates to the technical field of new energy utilization glass, and concretely relates to a preparation technology of an ultra-white glass substrate. Raw materials used in the inventioncomprise, by mass, 700 parts of fluoride, 30-60 parts of sulfate, 120-150 parts of titanium dioxide, 60-80 parts of chlorate, 50-70 parts of an acidic material, 15-30 parts of thiourea dioxide, 60-80parts of kaolin, 60-100 parts of a stabilizer and 50-80 parts of bentonite. A frosting liquid is prepared from raw materials; and a glass substrate is soaked in the frosting liquid, then the frosted rough surface is coated with an antireflection film, then the surface of the antireflection film is coated with a refection reducing film, and the surface of the refection reducing film is coated witha transparent super-hydrophobic coating. The antireflection effect, the refection reducing effect and the anti-pollution effect on the surface of the glass are good, and the glass substrate has good practical values and promotional values.

Description

technical field [0001] The invention relates to the technical field of new energy utilization glass, in particular to a preparation process of an ultra-clear glass substrate. Background technique [0002] Ultra-clear glass is an ultra-clear low-iron glass. The baffle made of ultra-clear glass is a key component of the secondary reflector part of the line-focused solar heat collection system, and its main function is to effectively reduce the convection and radiation heat loss of the heat collection tube. However, due to the reflection of sunlight on the surface of the glass baffle, the light transmission efficiency of the reflected light of the solar mirror field array (primary reflector) into the secondary reflector will be reduced. Moreover, the sunlight entering the secondary reflector has been concentrated by the primary reflector (condensation ratio: 10~50), so the reflection of the sunlight entering the secondary reflector on the surface of the glass substrate will si...
