Who has pvc foam board performance indicators ah?
Applicable temperature: -50 degrees Celsius -70 degrees Celsius Heating temperature: 70 degrees Celsius -120 degrees Celsius (making profiles) Bending strength: 45.6mpa Low temperature: (-5 degrees Celsius down the impact) 10 times zero broken life: not less than 50 years Product testing methods: (1) board: smooth and smooth, mechanical texture is not obvious, the surface color without color, milky white, no stains on the surface, no obvious pits, no pinholes, no thick holes, cracks. Note: non-milky white foam plate into the recycling waste plate, does not belong to the environmental protection board, environmental protection board does not lead (content is less than Europe and the United States standard). (2) plate side: incision smooth, fine pores, no pinhole, no thick hole, out of powder is not serious, no honeycomb, open fiber from the fall off, do not jump mouth. Note: The above situation to be careful, and then order to do the finished product trouble. (3) thickness measurement: caliper stand surface, the contact seamless seamless, left and right thickness uniform, left and right measurement, the deviation is large, thickness deviation positive and negative 0.2MM as normal. (4) Plate weight algorithm: Weight (g) = L * W * Thickness (cm) * Density, (5) Density algorithm: Density = Weight (g) / L * W * H (cm).
Specifications: 1220mmX2440mmX (3mm-30mm); white --- 3mm a 50 price how. The above specifications are referenced to the board, many boards are according to this standard.
There is no standard how good, we set the standard ah, what is what it is.
