How to make a simple distinction between high quality and inferior products:
Look at the appearance
1. See if the product is complete and incomplete.
2. Whether the color is uniform, whether there is obvious color difference, whether the color is bright and bright.
Touch products
1. Touch the surface of the product with the hand to see if it is smooth.
2. Whether the assembly parts are proper and the stacking is safe.
3. Whether the product has been naturally aging, the aging is reflected in the hard and brittle products, and the quality of the product is soft and has a soft feel.
toughness
According to the weight
1. Weigh the weight. In terms of the polymerization process and physical properties of raw materials, the proportion is light, indicating low crystallinity, high purity and impurity.
less
2. The products with the same structure and the same wall thickness are produced with the same raw materials and technology. Besides the above two characteristics, the weight is lighter.
