摘要:
The present invention relates to a method for manufacturing a wood section material, especially with respect to soft wood section material and its manufacturing method. It belongs to the wood processing field. This invention is achieved by the following technical plans: a type of wood section material manufacturing method includes the following steps: (1) wood preparation; (2) drying; (3) polishing; (4) hot pressing, which is to use two hot pressing boards with 140-200 °C to firmly press two surfaces of panel blank material; (5) pre-carbonization, which pre-carbonizes the panel blank material under 160 ∼ 200 °C; (6) carbonization, which carbonizes the panel blank material under 200 ∼ 225 °C; (7) cooling; (8) moisture content control. This invention is particularly suitable to make wooden floor boards and office furniture.

A method for cutting a plate glass capable of providing a satisfactory cutting face with excellent linearity also for a rather thick plate glass by preventing cullet from producing in cutting the plate glass utilizing thermal strain, wherein the plate glass is heated along a virtual cutting line by a heating burner after an incisure as a crack start point is engraved in the plate glass at a cutting start point, and the virtual cutting line part of the plate glass at the heated portion is locally cooled by mist generated by a cooling nozzle having a liquid jetting port at the center projected from a gas jetting port on the outer periphery to develop fine cracks at the incisure along the virtual cutting line so as to form cracks necessary for cutting the plate glass.

An optimized microwave barrier assembly for use in conjunction with a microwave wood heater. The barrier is configured to allow microwaves to pass therethrough in a TM ab ) mode, where a is 0 and b is an integer between 1 and 5. The barrier assembly is also configured to maintain a pressure differential across a window of the barrier assembly. Such a configuration can reduce or eliminate arcing in the barrier assembly, even at low pressures.

The invention relates to a method of machining a component having a wooden material, in particular a panel (2, 2') . In order to be able to machine panels (2, 2') more efficiently and reduce the risk of inaccuracies with such a method, a method has been proposed in which a high-energy beam, in particular a laser beam (6), is directed onto the component (2, 2') at a point to be machined and in which some of the material of the component (2, 2') is removed by the action of the beam (6).
