PVC foam board purchase considerations summary: watch the color of the foam board surface, measure the thickness of the foam board from all angles, look at the cross-section of the PVC foam board has no bubble holes, pay attention to the foam board density and thickness of the error, ask the businessman to show proof of safety and environmental protection certification.
The use of PVC foam board is very wide, small to advertising printing, bath cabinet production, carving design, large to the partition of the car and ship, bus floor, etc. will use PVC foam board. The PVC foam board issued in the market also has a variety of prices, from as low as 20 yuan a piece, there are high to 300 yuan a piece, if you buy poor quality PVC foam board, then we processed the finished product into a substandard product, how to correctly go to buy quality PVC foam board? Follow the study together.
One、watch the PVC foam board surface color: If the PVC foam board surface color yellowing, or color is not pure, with other miscellaneous colors, then, such foam board in the formula must be a problem, or the production process can not, if used for advertising printing, printing out the effect will be greatly reduced. Therefore, be sure to choose pure color, no color difference of PVC foam board.
Two、measure the eight thickness of the PVC foam board: because the thickness of the uneven PVC foam board will cause trouble for our secondary addition, such as the wrong size in some places. Therefore, we must measure the thickness of its eight parts is not the same, which eight parts? The four corners plus the middle part of the four sides.
Three、observe the cross-section of the PVC foam board has no pores: If the cross-section of the PVC foam board has pores, then the foaming of such foam board is certainly uneven, which is a poorer production process, it will be in the interior of the board, that is, the middle position will also produce bubble holes, then the force of such poor quality foam board will not be uniform, it is easy to make a place deformation or fracture.
There are bubble holes on the cut surface for unqualified PVC foam board.This is unqualified PVC foam board, there are serious bubble holes on the cut surface.
Four, pay attention to the merchant's deceptive means, such as stealing density or thickness: for example, you want to buy 0.55 density of PVC foam board, and the merchant only gives you 0.5 density, which can differ by tens of dollars ah, and the hardness of the plate is also to be lower on a circle, the weight of the plate is less several kilograms it; thickness difference of 0.5MM can also make the plate cheaper by tens of dollars, less to go several kilograms. So, we have to bring along a thickness gauge to be ready to check the thickness. If you do not know the density of the foam board, you can consult: 15167185483, Gege salesman will do their best to solve for you.
Five, pay attention to the PVC foam board is not environmentally friendly models: when we choose PVC foam board, be sure to businessmen to show their PVC foam board safety and environmental protection testing certificate, if there is no certificate, then it is likely to be produced from non-environmental materials, or back to the production of materials, to know that heavy metals exceed the standard PVC foam board is harmful to humans.
PVC foam board purchase considerations summary: watch the color of the foam board surface, measure the thickness of the foam board from all angles, look at the cross-section of the PVC foam board has no bubble holes, pay attention to the foam board density and thickness of the error, ask the businessman to show proof of safety and environmental protection certification.
