Embodiment 1

[0054] Such as Figure 1~5 Shown, in the embodiment, take MDF plank as example:

[0055] 1, the infrared pulse radiation heating method of plank surface powder solidification of the present invention, comprises the melting leveling that carries out successively and curing, curing is that the MDF plank 7 that is coated with powder coating is heated through the medium-wave infrared pulse irradiation area, heating It is high-temperature and low-temperature alternating heating, and the medium-wave infrared pulse irradiation area is composed of a continuous single medium-wave pulse irradiation heating unit, and the medium-wave infrared heating tubes 2 in the medium-wave infrared pulse irradiation area are vertically arranged The way.

[0056] The working curve of the single medium-wave infrared pulse irradiation heating unit is: heating→high temperature→cooling, the surface of the coating film is heated up to 160°C, and after curing at this temperature, it is then cooled to 120-14...

Abstract

The invention relates to an infrared pulse radiation heating method for curing board surface powder and equipment for implementing the method, which belong to the field of infrared technology application. The heating method uses the new concept of a medium-wave infrared pulse radiation heating unit, and pulsed high-temperature curing is performed for artificial MDF (medium density fiberboard) surface powder coatings by the aid of short-time pulsed high temperature, so that heat damage of a board surface is avoided. By the aid of a pulsed high-temperature curing accumulation effect, coated film curing time is greatly shortened, the heat absorption capacity of a board matrix is greatly decreased, and an MDF is ensured to be at the temperature lower than 100 DEG C during discharge. By the aid of the equipment for implementing the method, effective heating space and the length of a drying tunnel can be reduced, MDF surfaces in an automatic coating production line are ensured to be in the same heated state, coated films are uniformly cured, and an energy-saving effect is extremely remarkable.

Description

technical field [0001] The invention relates to an infrared pulse radiation heating method and equipment for powder curing on the surface of a wood board and belongs to the application field of infrared technology. Background technique [0002] At present, artificial wood boards such as MDF wood boards, HDF wood boards, LDF wood boards, and particle boards on the market can greatly reduce the release concentration of formaldehyde harmful substances inside the wood boards after being coated with powder coatings on the surface. Because the powder coating is 100% solid, it evenly covers the surface of the artificial wood board. Thereby artificial wood board becomes the green environmental protection product that people like. For example, the formaldehyde emission of particleboard is 2.8mg / L for the original board, and after electrostatic spraying powder coating, the formaldehyde emission is reduced to 0.1mg / L. [0003] Since wood cannot withstand high temperature, UV light-cu...
