Announcements | This kind of product customers to the bottom as the surface, focus on checking the bottom, both sides of the light is consistent, no gas marks, obvious flower surface, no wrinkles, bad roll must be changed. Note 1:1, under the same conditions of thickness, embossed, light fog, direct light and refraction direction, visually check the difference between the standard color of the finished product and the sample. 2. Take A4 sample of each finished product and compare it. Note 2: The finished product is compared with the sample or the standard template of softness and hardness by finger touch at normal thickness and temperature. Note 3: The finished product under the light inspection perspective, due to foreign bodies, impurities, decomposition infiltration caused by visible spots or brown color. Note 4: Horizontal or perspective (transparent products), such as a slender line shape with a hollow at the end of the phenomenon. Note 5: Unfold the finished product on the display platform, cut 5m length, and place it at both ends of the 5m finished product with a straight line. The largest difference in measurement is the skew. Note 6:1, both ends of the finished product roll into a neat cutting surface. 2. The concave and convex surface of the finished product should be controlled within 5mm with the ruler. Note 7: Shrinkage rate %= (L0 original length -L1 shrinkage length) /L0 original length ×100% |
