Embodiment

[0024] S1) Processing of the original glass sheet:

[0025] First, use a glass knife to cut the original glass piece of 15×10mm, then use a file to blunt the sharp corners, use a plastic brush dipped in decontamination powder and soapy water to repeatedly rinse the glass surface, and then rinse it with pure water. After drying in a drying oven at ℃, take it out and let it cool to room temperature, and use a special glass pen to number the back.

[0026] S2) Coating of glass samples:

[0027] Use the coating solution to be tested to coat the previously treated original glass, and then dry it at 110°C

[0028] Heat and dry in the box, place the dried glass sheet (coated side up) on the alumina refractory brick (length, width, height 22×11.5×2.2mm), and use a long-handled shovel to scoop up the refractory brick and the glass on it The slices are quickly put into a high-temperature furnace set and heated to 650°C for 5 minutes, and then the alumina refractory bricks and the glas...

Abstract

The invention discloses a method for detecting the adhesive force of a coating solution, and the method for detecting the adhesive force of the coating solution comprises the following steps: S1) cleaning a glass sheet; s2) carrying out coating treatment on the glass sheet; coating the pretreated glass sheet with a to-be-detected coating solution, then heating and drying in a drying box, flatly placing the dried glass sheet on an alumina refractory brick in a direction that the coating surface is upward, quickly placing the alumina refractory brick into a high-temperature furnace which is setand heated to 650 DEG C, firing for 5 minutes, then quickly taking out the glass sheet from the high-temperature furnace, and naturally cooling the glass sheet to room temperature indoors; s3) measuring the adhesive force; laying the glass sheet on a detection table with the coating upward, flatly adhering an adhesive tape to the coating surface, tearing off the adhesive tape upwards at a constantspeed of 90 degrees within preset time after the adhesive tape is adhered, and judging the quality of the coating surface by observing adhesive tape residues. The method is characterized in that detection method can rapidly and accurately test the film surface adhesive force of the coating solution, accurately judge the quality and application characteristics of the coating solution, and guide smooth production.

Description

Technical field: [0001] The invention relates to the technical field of processing photovoltaic glass, in particular to a detection method for detecting the adhesion of coating liquid after photovoltaic glass coating liquid. Background technique: [0002] Solar photovoltaic power generation is clean energy with zero pollution. China has become the world's largest producer of photovoltaic cells. Since power generation efficiency is directly proportional to photovoltaic glass, increasing the visible light transmittance of photovoltaic glass can increase the power generation of photovoltaic modules per unit area. The current mainstream approach is to prepare a layer of anti-reflection coating (AR) on the glass surface. High-performance anti-reflection coating can increase the conversion efficiency of photovoltaic modules by more than 2.5%. How to quickly detect the adhesion of the coating solution on the photovoltaic glass surface in the research and development stage has not b...
