Plastic-wooden composite profile conditioning chamber

Abstract

The invention relates to a plastic-wooden composite profile conditioning chamber which comprises a conditioning chamber, humidifying devices, a heating device and a ventilation device, wherein a compartment for containing a plastic-wooden composite profile is arranged at the front part of the conditioning chamber; an entrance is formed in the front side wall of the compartment; humidifying devices are arranged at the left and right sides of the compartment; the heating device comprises a microwave generator and a steam heater; the microwave generator is arranged at the rear part of the conditioning chamber; the steam heater and the ventilating device are arranged at the top of the conditioning chamber together. According to the plastic-wooden composite profile conditioning chamber, the plastic-wooden composite profile treated in the conditioning chamber is small in internal stress, high in size stability and wide in application scope; the plastic-wooden composite profile conditioning chamber is simple in structure and convenient to use; one conditioning chamber can contain plastic-wooden composite profiles produced by multiple plastic-wooden extrusion production lines; the existing extrusion production lines are completely reserved and the conditioning chamber has very good application prospect.

Description

technical field [0001] The invention relates to a wood-plastic composite profile health room. Background technique [0002] At present, traditional wood-plastic composite profiles are basically based on general-purpose plastic polyolefin (PE, PP, PVC) as the main matrix resin, filled with a certain amount of plant powder, and extruded through an extruder to obtain a certain interface status. Since the substrate is thermoplastic, the sheet must be cooled with cooling water during the forming process, so that residual stress is generated inside the sheet, and the existence of this stress causes the sheet to shrink during long-term use, which brings great harm to the project. defect. Contents of the invention [0003] The present invention makes improvements to the problems existing in the above-mentioned prior art, that is, the technical problem to be solved by the present invention is to provide a wood-plastic composite profile curing room, and the wood-plastic composi...
