One: Weigh.

The primary raw material of synthetic resin tile is polyvinyl chloride (PVC) with a specific gravity of about 1.4. Weighing 1 square meter of resin tile, component ÷ volume & asymp; 1.4 Proof that the resin tile main material is PVC, which can be used to ensure the service life of the product. The component ÷ volume > 1.4 proves that a large amount of heavy carbon synthetic resin calcium silicate and other fillers are added to the resin tile, which not only cannot ensure the service life of the product, but also the product is brittle and easy to be synthetic resin. Can be applied to simple temporary construction. (Because the volume measurement is not very convenient, we usually use a professional muffle furnace to do the ash incineration experiment. Since the resin does not leave ash after incineration, the ash is mainly non-combustible heavy calcium. The content of calcium powder, in general, the higher the content of calcium powder, the worse the quality and the lower the cost.)

Second: Burn 

It is mainly to smell ASA synthetic resin tile when they are burnt. Good quality ASA synthetic resin tile will be extinguished when it leaves the fire source. The poor quality PVC tile will not be extinguished immediately after leaving the fire source, and there is strong irritating smell.The reason is: the addition of a lot of heavy calcium carbonate inferior resin tile in order to make the synthetic resin tile have a certain flexibility, adding plasticizer between them, and this additive has a combustion-supporting effect, so that the synthetic resin tile is It does not meet fire protection requirements and has poor weather resistance. Cracking occurs under the irradiation of synthetic resin tiles in the sun. (Synthetic resin tile, the surface layer uses imported resin ASA, because ASA is non-flammable resin and very expensive. Therefore, if it is burned against the surface, the tile will be incinerated, which just clarifies that it uses high-quality resin and has high color retention. Anti-aging function.)

Third:Rubbing

The ASA synthetic resin tile is light in texture,when click the roof with a sense of boredom; the fake and inferior copy resin tile has a heavy feeling by hand. The whole roof knocking sounds crisp.

Fourth: Look at the appearance

The shape of the resin tile is generally clear, and the material itself is shiny; on the contrary, it is a fake resin tile. (The resin used in the exterior of the resin tile is generally matt color. If the reflective surface is mostly made of domestic resin, and the amount of application do not popular, the tile is easy to fade.)
