These problems affect later testing and observation of the color and clarity of the film.
In the evaluation phase, the existing evaluation method comprises the following steps: the rolled sample is manually cut into a proper size to be made into a sample book, and the heat-resistant stability and the transparency of different formulas are compared with the light transmittance by observing the color of the sample at different times.
The existing evaluation method has the following defects: (1) not objective: the influence of human being observed by naked eyes is large, the influence of an ambient light source is large during observation, and the evaluation result is unquantifiable; (2) inaccuracy: when the glove knitting wool is rolled, the dirt such as the glove knitting wool is rolled into the sample to influence the observation, the empty drum in the sample roll can influence the observation, and the diameter and the thickness of the sample roll cannot be consistent, so that the observation result cannot be accurate; (3) The samples are obtained by manual cutting, the sizes are not standard, the shapes are not regular, and the evaluation standardization and consistency are affected.
In view of this, there is an urgent need to design a new sample forming method of PVC flexible film so as to overcome at least some of the above-mentioned drawbacks of the existing sample forming method of PVC flexible film.
