7.观察复合效果,并随意取一样品,用手揉搓横断面处,然后剥离复合层,观察其复合强度.
8.有条件的可测试其“剥离强度”.测试方法如下：在复合材料纵向与横向各取长（250±2）mm,宽（25±0.5）mm的5个试样.将试样的基材与覆膜作出剥离口,放于拉力机上,沿长度方向拉开,读取最大负荷值F（N）,则每个试样的剥离强度δ（N/cm）为：
\x05δ=F/b
\x05式中 F-最大负荷值,N
\x05b-试样宽度,cm
\x05 剥离强度越大,说明基材与挤出薄膜粘合强度越大,复合的质量越好,剥离强度是复合材料最重要的品质指标,也是生产工艺和过程控制最关键的因素.
9.挤出薄膜的质量.薄膜表面应无气泡、鱼眼、裂纹、杂质；厚度应均匀,宽度略大于基材宽度.

7.观察复合效果,并随意取一样品,用手揉搓横断面处,然后剥离复合层,观察其复合强度.
7. Observe the composition effect, and take a sample freely, then knead the cross-section with hand, and peel off the composite layer, observe the composition strength.
8.有条件的可测试其“剥离强度”.测试方法如下：在复合材料纵向与横向各取长（250±2）mm,宽（25±0.5）mm的5个试样.将试样的基材与覆膜作出剥离口,放于拉力机上,沿长度方向拉开,读取最大负荷值F（N）,则每个试样的剥离强度δ（N/cm）为：
δ=F/b
式中 F-最大负荷值,N
b-试样宽度,cm
剥离强度越大,说明基材与挤出薄膜粘合强度越大,复合的质量越好,剥离强度是复合材料最重要的品质指标,也是生产工艺和过程控制最关键的因素.
8. If there is experiment condition, “peel strength” may be tested. The test method is as follows: 5 samples are taken in each longitudinal direction and transverse direction, respectively; the sizes of them are 250±2mm in length, and 250±0.5mm in width. Make a peeled end between base material and coating film of the sample, and put the sample on the tensile tester, pull it apart along the length, read out the maximum load value F(N), then the peel strength, δ（N/cm）, of each sample is:
δ=F/b
Where F is maximum load value (N)
b is sample width (cm)
The greater the peel strength is means the greater the adhesion strength between base material and extruded film is, and the better the composition quality is. Peel strength is the most important quality specification for a composite material and is the most critical factor in production process and process control.
9.挤出薄膜的质量.薄膜表面应无气泡、鱼眼、裂纹、杂质；厚度应均匀,宽度略大于基材宽度.
9. The quality of extruded film. The surface of the film should be free from air-bubbles, fish-eyes, cracks, impurities; the thickness of the film should be uniform, and the width should be a bit larger than that of the base material.
