The conductivity S of the water used at room temperature ~ (23~2)℃ should be less than 2S/cm. A new solution should be used for each test. Preparation of the solution: Add 45 boxes of sodium chlorite to 1L of pure water containing 45% sodium chlorite. The impurities in the solution should be less than 1%. The container and the shelf should be filled with chemically non-reactive materials with salt solution. Before the energy enhancement, the sample should be placed in the test container and changed to 400℃ salt water, kept at room temperature for 24h, take the sample, wash it gently evenly at 38℃, and press the test piece with a soft and clean cloth. Installation Identification by the method in Appendix D. 5.7 Low temperature test
Lenses without packaging: Keep in refrigerator at (-1 ± 3) for 2 hours, then store at (23 ± 3)℃ for 3 minutes. Follow the method in Appendix D for identification.
5.9 High temperature test
Lenses without packaging: Keep in oven at 155 ± 2)℃ for 30 minutes, then take out and store at (23 ± 3)℃ for 30 minutes. Identification by the method in Appendix D.
Note: The samples should not be subjected to damage tests such as grinding, salt water, water resistance, moisture resistance, etc. 5.9 Film adhesion
Place the lens on a glass tray in a desiccator: (The desiccator is also equipped with a steel cup, so that the lens can stand upright. The water level should not be higher than the tray.) The water level should not be higher than 2.5m above the desiccator. The glass dryer and the broken glass are operated under the following conditions:
Put the glass dryer in a box (60°C: 16°C) and keep the relative humidity in the glass dryer at 1%, then take it out and wait for the piece to return to normal temperature before testing the adhesion. Gently press the piece with a ruler (and a flat ruler) and weigh it. The ruler should be 1mm small and should not touch the light wire. The upper grid should be 10,000 pieces. However, the pieces should be transparent. Do not penetrate the lens material under the film layer to prevent it from being scratched. Use 3M invisible tape (Magic Tape, No. 810, width 19mm) to hold the 100 stoppers, and at a slightly faster and steady speed (not available, square!) the glue is combined and then opened (10"), the test can be done with a long-lasting tape. The outermost two circles are not used, and the invisible tape cannot be used repeatedly.
First pull up and then stimulate whether there is any adhesion to the coating, and then use the reflective tape to check whether there is any adhesion to the coating. Check the grid on the pin with a light or use a lens. If the hard film is peeled off, there will be white light instead of black light. If the film is peeled off, the color will change. The edge of the grid will not peel off. However, there is a way to shine into the film, which is judged as defective. 5.10 Use size of coating area

Description of the total reflectance ratio of the anti-reflection film QB26B2-2005
The ratio of the amount of light reflected from the light surface to the incident light flux is increased, and the difference in the reflectance ratio at the visible spectrum center is reduced. It is expected to reduce reflection, and the reflectance ratio of the light in the center of the light spectrum is very low, and the reduction is very obvious at the light supply end and the red end. Big. Although! For the lower light reflection, the total reflection light product is more effective than the old negative color of the world: the world is the light of the current generation.
-weight () of the average reflection ratio: a section of the village will be higher than,: a certain war this abdomen, its other reflection film is compared with the correction in the center of the light spectrum reflection, the greater the other end of the cylinder color thanks to its lower light reflection ratio, then the translator has the expectation that the former is lower than the latter
Therefore, this ratio can be used as an additional information on the performance of the reflective film selection. : The difference in the scene, the light at the end of the reflection ratio is higher, "stop the ship and reflect the light by the user, position 2: Dianchuan:

B. 1.5 Sample
The edge piece prepared by this method: its front garment has a thickness of less than 8mm and a focal length of 0.25mm. The packaging should be thoroughly cleaned and dehumidified to remove large particles and contaminants. 2 Test
Under the test conditions of 5.1K, clean the sample with a cotton-grade absorbent or use an isocyanate to determine the haze value of the product without friction. (Every time the connection is rotated 90", a test value is obtained. Four test values ​​can be obtained in sequence within 3 days, and then the average value of the four times is stored in the table. The sample is fixed, and the center of the lifting rod is closed. The convex surface is the same as above. A steel wire is glued to the center of the mold, but the steel wool is directly proportional to the connection direction (Figure B.1), and the total weight is added to the convex surface of the single product (Figure B.3). Dynamic friction test machine: reciprocate and rub the product that has undergone the above-mentioned grinding test for 1000 times, and then use paper to absorb or underarm, and measure the order and position of the initial penetration value. Measure the haze value after 4 instantaneous observations, and take the average of the 4 measured values. Calculation of results: The difference between the haze value of the sample after friction and the value before friction is shown in Figure. The calculation direction of the steel wool is shown in Figure.2 Folding of copper velvet
