Multi-purpose sports flooring manufacturing process and its pre-construction testing
Oct 18, 2018

Multi-purpose sports flooring is a sports flooring specially developed for sports venues using polyvinyl chloride materials. Specifically, polyvinyl chloride and its copolymer resin are used as main raw materials, and fillers, plasticizers, stabilizers, colorants, etc. are added. The excipients are produced on a continuous sheet of continuous material by a coating process or by calendering, extrusion or extrusion.

 

Multi-purpose sports flooring is generally laminated from a multi-layer structure, with a wear layer, a fiberglass layer, an elastic foam layer, a base layer, etc., and such a floor is widely used. However, no matter which occasion it is used, the floor needs to be tested before the construction of the multi-purpose sports floor.

 

The specific method is to use temperature and humidity meter to detect temperature and humidity. Indoor temperature and surface temperature should be 15 °C. It should not be constructed below 5 °C and above 30 °C. The relative air humidity suitable for construction should be between 20% and 75%. And the moisture content of the base layer is measured using a moisture content tester, and the moisture content of the base layer should be less than 3%.

 

In addition, the strength of the multi-purpose sports floor base should not be lower than the concrete strength C-20, otherwise the appropriate self-leveling should be used to strengthen the strength. The hardness tester shall have a surface hardness of not less than 1.2 MPa. For the construction of PVC floor materials, the unevenness of the base layer should be less than 2 mm in the range of 2 m ruler, otherwise the appropriate self-leveling should be used for leveling.
