Anti-glare glass is also called anti-reflective glass or non-reflective glass. Anti-reflection glass Anti-reflection glass reduces the reflectivity of the glass surface ≤ 2%, the transmittance ≥ 80, and the gloss ≥ 60. It is a kind of glass with special surface treatment. The principle is to process high-quality glass on one or both sides. It has a lower reflectance than ordinary glass, reduces the light reflectivity to less than 1%, thereby reducing the interference of ambient light, improving the sharpness of the picture, reducing the screen reflection, making the image clearer and more realistic. Viewers enjoy better visual effects. First, use: suitable for all kinds of monitors and protection screens, museum art protection glass, various high-end photo frame glass. 2. Detection standard: optical index requirements 1. Light transmittance: 88% Min. (380 ~ 700nm visible light wavelength range), measured by spectrophotometer. 2. Gloss: 1) Test instrument: Gloss meter 2) Test method: As shown in the figure below, select 5 points on the original film for the gloss test, and at each point, the instrument reads every 90 degrees Once, two times in total, and then averaging the 10 test data to obtain the gloss value of the original sheet. Note that for single-sided anti-glare glass, the anti-glare treated surface must be tested. 3) Gloss standards: a. There are two kinds of procurement specifications for anti-glare glass gloss: 100 ± 10 and 80 ± 10. IQC conducts incoming inspection according to the standards of 100 ± 13 and 80 ± 15, respectively. b. Conventional size glass with a size ≤20 "requires the difference between the maximum and minimum gloss of the same piece of glass ≤10; Large size glass with a size> 20" requires the difference between the maximum and minimum gloss of the same piece of glass ≤20. Appearance inspection Appearance defect definition 1) Round defect: Appears as a round defect, such as bubbles, white spots, scratches, pits, foreign objects, anti-glare rounded defects and anti-glare round defects. 2) Linear defects: linear appearance defects, such as scratches, scratches, foreign objects, anti-glare treatments, and non-glare line defects. 3) convex defects: impurities or other defects protruding from the glass surface. Appearance inspection method The specific inspection method is shown in the figure: First, hold the two short sides of the glass with both hands to inspect the long direction; then hold the two long sides of the glass to inspect the wide direction; generally the long direction is the main direction. (Or put the glass horizontally on the shelf, the light source is under the glass) Inspect the vertical direction first according to the appearance inspection standard. The inspection time is 20-30 seconds. Dimension inspection 1. Length and width inspection 1) Allowable deviation: The allowable deviation of the length and width of anti-glare glass is ± 0.5mm. 2) Inspection method: Use a large vernier caliper to measure the distance between two parallel sides. 2. Thickness inspection 1) Allowable deviation: The allowable deviation of the thickness of anti-glare glass is ± 0.2mm. The thickness of the same piece of glass is different. The thickness is 3mm is 0.2mm, and the thickness is 4mm and 6mm is 0.3mm. 2) Inspection method: Use an outside diameter micrometer with an accuracy of 0.01mm to measure at the midpoints of the four sides within 15mm from the edge of the glass plate. The thickness difference of the same piece of glass is the difference between the maximum value and the minimum value of the four measured values. 3. Diagonal inspection 1) Diagonal difference requirements: The difference between the two diagonal lengths should not be greater than 0.2% of the average diagonal length. 2) Inspection method: Use a steel tape measure with a minimum scale of 1mm to measure the distance between the apexes of the corresponding corners of the glass. Anti-glare glass is suitable for all kinds of displays and protective screens, museum art protection glass, various advanced photo frame glass and so on.
