Embodiment 1
[0041] A method for producing interior wall panels and creosote with Chinese fir, specifically comprising the steps of:
[0042] (1) Chinese fir treatment
[0043] The bark of the Chinese fir is peeled off, and the peeled Chinese fir is cut into planks with a saw to obtain a Chinese fir plank, the thickness of the plank is 10mm, and the length is 1m.
[0044] (2) rough planing
[0045] Above-mentioned fir board is carried out rough planing, the surface planing of fir board.
[0046] (3) Anti-corrosion treatment
[0047] The rough-planed fir boards were steamed at 160° C. and 0.8 Mpa for 4 minutes, and then treated with 15 wt % hydrogen peroxide solution for cooking and anticorrosion. The cooking time was 1.5 hours.
[0048] (4) drying
[0049] The fir board after the antiseptic treatment is dried at 60-70°C until the moisture content of the board is below 7%.
[0050] (5) fine planing
[0051] After drying, the fir boards are finely planed to make the surface and corners...

[0061] A method for producing interior wall panels and creosote with Chinese fir, specifically comprising the steps of:
[0062] (1) Chinese fir treatment
[0063] The bark of the Chinese fir is peeled off, and the peeled Chinese fir is cut into planks with a saw to obtain a Chinese fir plank, the thickness of the plank is 12mm, and the length is 1.5m.
[0064] (2) rough planing
[0065] Above-mentioned fir board is carried out rough planing, the surface planing of fir board.
[0066] (3) Anti-corrosion treatment
[0067] The rough-planed Chinese fir boards were steamed at 180° C. and 0.9 Mpa for 3 minutes, and then treated with 10 wt % hydrogen peroxide solution for cooking and anticorrosion. The cooking time was 2 hours.
[0068] (4) drying
[0069] The fir board after the antiseptic treatment is dried at 60-70°C until the moisture content of the board is below 7%.

Abstract
The invention discloses a method for producing an indoor wall plate and creosote through cedarwood. The cedarwood is used for producing the indoor wall plate, cedarwood waste is used for extracting the creosote, the cedarwood is peeled and cut into a cedarwood board in a sawn manner, the cedarwood board is subject to rough planing, the surface of the cedarwood board is subject to planing, steam isused for cooking, a hydrogen peroxide aqueous is used for cooking, the cedarwood board is heated and dried, finish planing is carried out, the connecting face of the cedarwood board subject to finishplaning and a base material is glued, and pressed into a wall plate, the wall plate subject to press fitting is subject to sanding treatment, paint spraying and drying, and the indoor wall plate is obtained. The cedarwood waste generated in the cedarwood machining process is pulverized and dried, dry distillation is carried out, condensate liquid is collected, oily objects in the condensate liquid are separated, and the creosote is obtained. The method is simple and easy to implement, raw materials are cheap and easy to obtain, the utilization value of the cedarwood is improved, the obtainedindoor wall plate does not contain formaldehyde, is durable and convenient to maintain, the produced cedarwood waste is used for extracting the creosote, and waste resource utilization is achieved, and the method is environment-friendly.
Description
technical field [0001] The invention belongs to the technical field of interior decoration materials, and in particular relates to a method for producing interior wall panels and creosote from Chinese fir. Background technique [0002] Chinese fir, also known as: sand wood, sand tree, etc., belongs to Pinaceae, fir tree, up to 30 meters, diameter at breast height of 2.5-3 meters; bark grayish brown; winter buds nearly round, male cones conical, female cones Single, ovoid cone, 2.5-5 cm long, 3-4 cm in diameter; seeds are flat, covered with seed scales, long ovate or oblong, flowering in April, and cones mature in late October. [0003] Chinese fir wood is yellowish white, sometimes the heartwood is light reddish brown, soft, delicate, fragrant, straight texture, easy to process, specific gravity 0.38, strong corrosion resistance, not eaten by termites, generally used in construction, bridges, shipbuilding, Ore pillars, wood piles, poles, furniture and raw materials for the ...
