Vacuum vacuum molding machine how to detect the difference between vacuum forming glue quality?

Vacuum vacuum molding machine how to detect the difference between vacuum forming glue quality? 1, the cohesive force of test: after vacuum forming slot no rebound, no shrinkage, such as doing peel test, on the PVC to stick with sawdust, middle empty vacuum forming glue on the edge of use or high temperature will soon take off. Test method is: do after vacuum forming edge peel test, to see how much force will strip away, and see whether the skin after peeling PVC glue has a lot of wood chips, And wood completely said PVC more and are less vacuum forming glue quality is poor, poor bond) 。 2, warm test: namely, high temperature resistant, low temperature performance, and moisture, around the climate is different, because such as warm sex bad vacuum vacuum forming gel when the container export or summer high temperature especially easy to take off the edge and slot rebound. Minimum 75 ℃ qualified of heat-resistant, 65 - because of temperature in the container 70℃。 The most simple test of temperature resistance is vacuum forming directly in the sunshine after 24 hours, such as straight off half an hour or more with no edge, no rebound is good vacuum forming of heat-resistant rubber, when the container or high temperature wouldn't have to take off the edge, slot rebound phenomenon. 3, particles presents detection: good vacuum vacuum forming glue spraying little or no surface pitting after vacuum forming, after making products with poor like sand, let a person a see uncomfortable, at the same time seriously affected the image of the enterprise. Carefully to detect more than 3, basic can determine the vacuum vacuum forming the pros and cons of the quality of the glue.
