Abstract

The invention relates to the field of plastic board or sheet products made of plastics or plastic materials, and in particular relates to a double-layered ring-shaped metal strip extruder and a using method of the double-layered ring-shaped metal strip extruder. The extruder comprises an upper ring-shaped metal strip machine (1) and a lower ring-shaped metal strip machine (2), and is characterized by further comprising hydraulic cylinders (3), guide rods (4), connecting pipes (61), heat conduction pipes (62), bearings (63), a power transmission device (7) and a temperature control device (8). The using method is characterized in that the upper ring-shaped metal strip machine (1) is adopted to extrude surfaces of the plastic boards. The plastic board produced by the invention is high in bending stress, bending modulus, and dimensional stability, good in mechanical property and wide in application range.

Description

technical field [0001] The invention relates to the field of plastics or plastic plates or sheet products produced from materials in a plastic state, in particular to a double-layer annular steel belt extruder and a use method thereof. Background technique [0002] In order to make the plastic sheet have a certain strength and meet the user's requirements for the mechanical properties of the plastic sheet, it is usually achieved by adding a certain amount of reinforcing materials into the plastic material, especially the fibrous material is the most obvious. Glass fiber mat reinforced plastic sheet has extremely high flexural strength, flexural modulus and dimensional stability, and can meet many fields that require high mechanical strength of the sheet. But only plastic sheets that combine plastic and glass fiber mat have high flexural strength, flexural modulus, and dimensional stability. The current plastic sheet production equipment is difficult to realize the laminar f...
