How to distinguish the quality of extrusion board

The plank that extruded sheet manufacturer produces here is a kind of brand-new heat preservation material, in the process that USES, it can show good flame-retardant performance, can reduce the circumstance that fire breaks out so, at ordinary times, how do we need to do ability to differentiate this product its quality?

Want to distinguish between good sheet quality, first of all need to pay attention to the product of its surface is smooth level off, whether there is a crack on the surface, the second in the use of nails to press it, see if his above refers to the pressure of imprinting, appeared again, we can also look to see if it appeared the phenomenon of deformation, for high quality plate, in the process of use, require plank of its surface is smooth level off, can’t appear any deformation of the phenomenon, in the end, you can look at it whether has the flame retardant performance, is lit it, and see if it’s easy to burn.

If you have any questions, please feel free to share them with us. I believe we can all learn a lot in the process.
