1、夹胶玻璃pvb胶片厚度确定原则一般按一下考虑这几个因素：板块的形状（如弯曲，异型），板块的尺寸（一般可以短边800mm分界），基片的性质（如是否钢化）常用玻璃夹胶片最小厚度可以按以下要求确定：1）基片为浮法玻璃基片厚度mm         短边长度≤800mm　　短边长度＞800mm≤6                          0.38                               0.388                            0.38                           0

5、               半径长度＞3m　≤8                       2.28                                   3.04＞8                             3.04                                       3.04                    4）热弯玻璃基片厚度          半径长度≤3m　　                    半径长度＞3m　　      ≤6               

6、        0.76                                       1.14～1.52＞6                      1.14                                          1.52             注意事项：1）两片玻璃相差厚度最好不要超过2mm；2）不宜采用仅一片钢化或半钢化玻璃的结构；3）上述基片厚度应以较厚的玻璃来计算；
