How to distinguish the quality of blister door panels

How to distinguish the quality of blister door panels
1. Identification method of substrate quality
The quality of the base material directly determines whether the cabinet door has the ability to eat nails twice, the ability to hold nails, the degree of deformation of the finished blister board, and the environmental performance of the finished blister board. The density of a good blister door panel is different from that of ordinary substrates. The best way to distinguish is to select small pieces of the same size and weigh it. For blister door panels with higher density, it is relatively easy to hold nails. The ability will be better and the deformation will be smaller.
2. Methods of identifying the quality of membrane skin
The quality of the film directly determines the grade and performance of the finished blister door panel. A good blister film should reach a certain thickness, the film skin should be evenly glued, and the color should be stable. If the thickness of the PVC film is low, it will cause whitening and orange peeling on the surface when pressing the corners. Some manufacturers choose to reduce the pressure of the blister machine in order to deal with these two phenomena, which reduces the whitening and whitening to a certain extent. The board is deformed, but the adhesion and pressure firmness of the PVC film and the substrate cannot be guaranteed. The main problem caused by uneven film backing is that the PVC film and the substrate cannot be properly bonded and pressed. The PVC film itself cannot be bonded to the substrate with glue through the blister machine. The glue must be rolled on the back during production. We call it back glue, whether the back glue is uniform or not, and the quality directly affects the adhesion between the PVC film and the substrate. The color problem is the most noticeable problem of the finished blister board. Yellowing is an inevitable problem, but the stability of the PVC surface texture and color must be guaranteed, otherwise it is likely to occur during the wiping process of normal use Fading problem.
3. Surface treatment of blister door panels
The surface treatment is related to the overall image of the finished blister board. If the orange peel phenomenon is serious, the entire door panel looks darker (orange peel refracts light), and the high-gloss blister door panel is very obvious at this point.
4. The workmanship of blister door panels
This is the most troublesome problem during use. It is mainly manifested in the adsorption at the corners. If there is a phenomenon of glue opening, the blister cabinet door panel may have water absorption deformation and cracking of the PVC film itself during use. When choosing, you can use your fingernails to dig out the part where the PVC film and the sheet are bonded. Good workmanship (including good adhesive and adhesive glue) will not be pulled off with a little force.
