The surface material of synthetic resin tiles is key; the choice of surface material directly affects the service life of the resin tiles. In most cases, ASA colored co-extruded material is usually selected, and the product's weather resistance directly leads to the service life of synthetic resin tiles (the 10,000-hour weather resistance test report from the **** Chemical Building Materials Testing Center is equivalent to an actual service life of over 20 years). Overall, the quality of synthetic resin tiles depends on the ratio of surface material to resin.
The specifications of synthetic resin tiles are usually 0.72M and 0.88M, with a thickness of 3MM and a weight of 6KG per square meter. Standard synthetic resin tiles will present relevant testing reports from the **** Chemical Building Materials Testing Center when purchased (it is not allowed to sell in the market without the testing report from the **** Chemical Building Materials Testing Center):
1. Artificial aging test report (10,000 hours of artificial aging is equivalent to actual use of over 20 years)
2. Low-temperature drop hammer impact (0℃, 1h) test report (a 1-kilogram steel ball dropped freely from a height of 1 meter onto the tile surface does not produce cracks; after 10 impacts at low temperature, the product shows no damage. After 10 freeze-thaw cycles, the product shows no hollowing, bubbling, peeling, cracking, or other phenomena.)
3. Fireproof building material test report (the fire prevention specifications for interior decoration design A2.6 plastic combustion performance determination B1 level or above)
Standard synthetic resin tiles have very good load-bearing performance. According to the inspection by the **** Building Materials and Components Quality Supervision Station, under a support interval of 750MM and a uniformly distributed load of 150KG, there is no damage. Poor quality synthetic resin tiles may break when workers step on them during construction.
Standard synthetic resin tiles can resist corrosion from various chemical substances such as acids, bases, and salts for a long time. In experiments, soaking in salt, alkali, and various acids below 60% for 24 hours shows no chemical reaction. Poor quality synthetic resin tiles with surface layers using certain pigments may undergo chemical reactions, even leading to discoloration.
