One: Weigh the proportion. The main raw material of resin tile is polyvinyl chloride (PVC).
Its specific gravity is about 1.4. Weigh a 1 square meter large resin tile,Weight÷volume≈1.4 It proves that the main material of the resin tile is PVC, which can effectively guarantee the service life of the product.Weight÷volume>1.4 proves that a large amount of heavy carbon synthetic resin calcium carbonate and other fillers are added to the resin tile, which not only cannot guarantee the service life of the product, but also the product is very brittle.It is easy to synthesize resin tiles and can only be applied to simple temporary buildings.(Because volume measurement is not very convenient, we usually choose professional muffle furnace,Do an ash burning test. Since the resin does not leave ash after burning,So the main ash content is non-combustible heavy calcium,In this way, we can get the content of calcium powder. Generally speaking, the higher the content of calcium powder, The worse the quality, the lower the cost. )

Second: Burn with fire. Ignite a corner of the resin tile with fire. After the fire source leaves,
The flame synthetic resin tile immediately rests on its own.The fake and inferior resin tile flames have the potential to spread and have a greater pungent smell.The reason is: fake and inferior resin tiles with a lot of heavy calcium carbonate added,It is to make synthetic resin tiles have a certain flexibility,Plasticizer is added to it,And this additive has a combustion-supporting effect,

The synthetic resin tile produced in this way does not meet the fire protection requirements and has poor weather resistance.Cracks occur under the sunlight of synthetic resin tiles.(Synthetic resin tile, the surface layer uses imported resin ASA,Because ASA is a non-flammable resin and very expensive. So if you fire on the surface,The tile will burn, which just shows that it uses high-quality resin with high color retention,Anti-aging performance. )

Third: weigh and knock with your hands.
The resin tile is light in texture, and there is a dull feeling when the board and board hit;The fake and inferior imitation resin tile has a heavy feeling by hand. The board and board knock sound is clear and crisp.

Fourth: Look at the appearance.
The resin tile has a clear outline and the material itself is shiny;
On the contrary, it is fake and inferior imitation resin tiles.(The asa resin used on the surface of the resin tile is usually matte color,If it is a reflective surface, most of the domestic resin is used, and the amount used is small,Tile fades easily
