Method of testing the performance of hollow board
Methods for testing the performance of hollow panels
1. Light transmission detection
Use the naked eye in a fluorescent lamp or a place about 40cm away from the product under sunlight Check the color of the hollow board, the one with high light transmittance is the new material hollow board. Otherwise, it is ordinary.
2. Dimension measurement
The thickness measurement uses vernier calipers to measure the thickness of the hollow board in front and back, left and right, and the thickness of the hollow board is measured. The product with an error of 0.03 mm is a qualified product.
3. Bending test
Use a 50*1000mm hollow board. Middle fold. The number of bending is more than 200 times without cracking. It is a qualified product.
4. Density test
Cut 5 pieces of hollow board, the same thickness, the size is 1000*1000mm. Each piece is weighed by an electronic scale. The weight error is 15-30 grams for qualified products.
In short, when buying hollow boards, you must buy them from regular manufacturers, because they are professional and have guaranteed quality. Guangzhou Qusheng Plastic is a manufacturer specializing in the production of hollow boards, and hope to help you.
