Basic points for inspecting Profile Pvc

What are the three basic points for inspecting Profile Pvc? Some customers still don't know much about the inspection after ordering the Profile Pvc produced by our factory. Our factory has specially published an article to explain this.

The basic method for inspecting Profile Pvc, now take the 160g national standard Profile Pvc as an example to explain what the national inspection standards are.
1. Tensile test
Take 2 samples of 3 meters of 160g Jinguo Profile Pvc, and then place them horizontally on the tensile testing machine. There is a tensile display on the machine, then turn on the machine to test the tensile force and record the value. Then put the second sample vertically on the tensile testing machine, turn on the machine, record the value, and the horizontal and vertical tensile forces are not less than 1080N and 840N, which means that the tested product is qualified.
2. Gram test
Take 10 meters of sample, and then weigh it on the scale to see if the average gram weight per meter can be reached. If it is reached, it means that the product is qualified.
3. Appearance requirements
First, the Wall Corner must be a regular square, and the Wall Corner size is required to be 4mm*4mm. Then observe whether the Profile Pvc is broken, short, missing, cut, torn, skewed, dirty, uneven curling and debris, which means it is qualified.
The most important thing is that the material of the Profile Pvc itself is specially prepared. Our factory specializes in the production of export standard 140g-160g gold pot national standard Profile Pvc.
