1, composition test, the raw material of suspended assembled floor is PP polypropylene, and high-purity polypropylene must be used, so the assembled floor produced by this raw material is of high quality and durable. If the suspended floor produced with second-hand recycled materials is absolutely unable to pass the test, some manufacturers use engineering plastics to produce suspended assembled floors, which are obviously not suitable for use as floors because of the different characteristics of raw materials. Determining the composition is the most basic requirement.
2, green environmental protection testing, mainly to detect whether the suspended floor has irritating smell and volatile toxic components. The products that have passed the test meet the requirements. On the contrary, we should pay attention to whether the products with bad smell have problems with quality and raw materials.
3. Low temperature resistance test: This is a national test requirement. The sampled suspended floor should be kept in the freezer for 24 hours, and the temperature should be set at -40 degrees. After that, it is necessary to check whether there are cracks in the floor, and there is no obvious color difference. The suspended assembled floor that passed this test can be laid on the sports ground in the north, and can resist the cold situation of tens of degrees below zero in winter in the north, especially in the northeast.
4. Rebound test: Half of the products of suspended assembled floor are laid on various courts, such as basketball courts. Due to the elastic technical requirements of basketball court pavement, the detection standard requires that the rebound rate of suspended floor should be above 90%, and the qualified suspended floor should meet the standard.
5. Load-bearing rolling test: Durable suspended floor is one of the first choice products for sports venues. We have done a test, let a large truck with a load of several tons pass through the paved assembled floor, and the suspended floor is intact, which proves that the floor that meets the requirements is not afraid of rolling.
6. Aging test: mainly to test the fading and cracking of suspended assembled floor. Irradiate the floor for a certain period of time with a high-intensity special testing instrument, and then check whether there are cracks and fading differences on the floor surface.
7. High temperature resistance test: The floor of the sample to be tested is required to be placed in a high temperature box with a temperature of 70 degrees for 24 hours. The test standard requires no melting, no cracking and no obvious color difference after 24 hours. Qualified suspended floor must meet the strict high temperature test requirements of national sporting goods.
8. Appearance quality inspection: this is mainly to check the color uniformity of the sample floor. It is required that there is no obvious color difference, which means that there is no foaming, the overall plasticization is good, and there is no burr on the surface. It is also required that the matte design has no obvious light emission to protect athletes' eyes from irritation, especially for developing children and adolescents.
9. Panel friction test: The national requirement for the floor to be used as the ground paving material of the sports ground is that the friction coefficient is between 0.5 and 0.7, and the test results of the suspended floor should meet the requirements of the national sports floor.
