The thermoplastic composite sheet may include between 50 and 99 weight percent of the thermoplastic material and between 1 and 50 weight percent of the lightweight material. The thermoplastic composite sheet may be free of reinforcing fibers.

Provided are a quality inspection method and a quality inspection system for unvulcanized rubber material. A final dielectric constant measurement device detects the dielectric constant of a final rubber material in which a compounding agent of predetermined type is mixed with unvulcanized rubber, and a calculator calculates a compounding ratio of the compounding agent to the final rubber material based on the detected dielectric constant, determines whether or not the calculated compounding ratio is in a preset compounding reference range, displays a determination result on a monitor, and adjusts a ratio of the compounding agent fed into an extruder to the unvulcanized rubber such that the calculated compounding ratio is within the compounding reference range.

The present disclosure discloses a multi-layer co-extrusion stone plastic floor. The multi-layer co-extrusion stone plastic floor includes at least one co-extrusion stone layer, the co-extrusion stone plastic layer including a first stable layer, a stone plastic rigid layer, and a second stable layer successively. A size change rate of the first stable layer and the second stable layer is within a range of 0 to 0.12% within a temperature range of −15° C. to 80° C. At least one of the first stable layer, the stone plastic rigid layer, and the second stable layer includes composite particles of acrylate copolymer (ACR)/nano SiO.sub.2. The multi-layer co-extrusion stone plastic floor has improved strength, improved thermal stability and reduce thermal deformation by adding stable layers above/below the plastic rigid layer and adding the composite particles of ACR/nano SiO.sub.2.
