Will always be first choice when buy PVC board, but we buy PVC board and should not be tested by professional technology, that will need to manually choose ourselves, the following will introduce how to manually by small make up for you test!
The PVC sheet was bent by hand; Take a piece of gusset plate, hold horizontal and longitudinal bend with two hands, if it is inferior plank, it is easy to break apart. And good quality of the plate, it's not the case, even if is not broken or split to produce permanent deformation, at the same time testing the roughness of good quality PVC board gusset plate, strength and toughness is good, in areas such as the surface and inner rib in sawing, won't appear crack, and curf flush, burr, the phenomenon such as crack, inner surface and inner rib section smooth, does not have obvious bubbles.
The inferior gusset blade saw the burr, the internal reinforcement and the board of the board easy to collapse, the crack, and the inner surface roughness, the internal gluten bubble much, in the use of the nail to try to print the face; The printing pattern of printing gusset plate has a layer of glazing film, the effect that protects pattern and decorative pattern, this film must have certain hardness, ability is able to resist friction. To check the hardness of the film, try and test the film back and forth with the nail on the surface of the film, and then see if it leaves a scratch. Generally speaking, the quality of the gusset plate is not to leave scratch, if appear scratches, explain the hardness that protects the photofilm of printing pattern is not good, use is easy to scratch.
