摘要： The present invention makes it possible to improve the reliability of fire resistance with regard to wood materials containing a fireproofing treatment agent such as a semi-incombustible wood material while also improving both the ease of procuring raw materials and mass productivity. This panel board 11 comprises front/back veneer 21 constituting the front and back thereof and a core veneer layer 31 layered between the front/back veneer 21. The veneer fiber direction of the front/back veneer 21 is substantially parallel to the lengthwise direction of the panel board. The core veneer layer 31 is a layer obtained by stacking a plurality of sheets of core veneer 32 in the thickness direction. The veneer fiber directions of all of the sheets of the core veneer 32 are substantially orthogonal to the lengthwise direction of panel board 11. The front/back veneer 21 has a thickness of 1.5-4.0 mm, and the thickness of the core veneer layer 31 is equal to or greater than the total thickness of the front/back veneer 21. Lathe checks and cracks are exposed on the board grain surfaces of all the front/back veneer 21, and an aqueous solution of a fireproofing agent is infiltrated therefrom.

摘要： The present invention improves the reliability of fire-resistance performance, and suppresses a drop in strength and a drop in Young's modulus for bending, with regard to a structural LVL containing a fireproofing chemical for fire-resistant structural wood material-use. The present invention is the LVL 61 for structural use comprising a plurality of raw material veneers 51 layered in the front-back thickness direction via adhesive layers therebetween. Each of the raw material veneers 51 is a wood material having a fireproofing chemical injected to the interior thereof and is constituted from a site of sapwood part alone, a site of heartwood part alone, or, a site wherein a sapwood part and a heartwood part are mixed. Injection holes 62 are provided, each having a circular cross section and extending in the thickness direction from each of the front surface and the back surface of the LVL 61. The injection holes 62 traverse through the plurality of raw material veneers 51 and the adhesive layers. On the front surface and the back surface, respectively, plurality of the injection holes 62 are aligned while leaving an interval therebetween in the width direction and in the length direction of the LVL 61. The injection holes 61(U) from the front surface and the injection holes 61(D) from the back surface are disposed at different positions from one another in the width direction and in the length direction.

摘要： The present invention relates to a process for the production of impregnated wood pieces, in particular for use in pencil production, wherein the process comprises two process stages, namely
a) a first process stage, comprising
- a first impregnation step, in which an untreated wood piece is at least partially, impregnated with a first aqueous impregnating solution of an impregnating agent selected from the group consisting of 1,3-dimethylol-4,5-dihydroxyethylene urea or a derivative or modification thereof, and a catalyst, and
- a subsequent curing step, in which the impregnated wood piece is cured in a hot steam atmosphere at an elevated temperature above 100°C, and

b) a second process stage comprising a second impregnation step, whereby the impregnated, cured wood piece is at least partially impregnated with a second aqueous impregnating solution of a wax emulsion paraffin based as an impregnating agent.
The invention further relates to an impregnated wood piece obtainable by such a process and a pencil having a lead and a shaft, wherein the shaft is made from or comprises such an impregnated wood piece obtainable by such a process.
