Problems solved by technology

[0002] At present, wood-based panels at home and abroad are widely used. Most of the industrial materials such as home decoration, construction, and transportation are leftovers after wood processing and residues after harvesting, so that the wood can be comprehensively utilized, but this kind of raw material must be fully used. The disadvantage is that the sources of raw materials are scattered, the varieties are mixed, and the processing plants have to receive and transport the goods in forest areas hundreds of miles away. The implementation of the project has reduced the amount of wood harvested, and the source of raw materials is facing a serious shortage. At present, the types of wood-based panels produced are few, the quality is poor, and some production pollutes the environment. Wood, which is scarce and expensive, limits production

Embodiment 1

[0038] Select European and American poplar varieties, and use artificial cuttings on narrow row slopes with alternating wide and narrow rows. The width of the wide row is 0.7m, and the width of the narrow row is 0.3m. 2,000 trees are planted per mu, and the spacing between the rows is 60mm. Furrow irrigation is carried out between narrow rows, and the water holding capacity of the field is maintained at 70%. Furrow irrigation is not used when the rainfall is sufficient. Use herbicides to weed, and apply biological fertilizer in June and July, 2kg per mu. After emergence, pick the side buds and keep growing on a single pole. Harvest the strips one year later. After cutting the strips, peel them and cut them into 3cm long, 2.5cm wide, and 0.2cm thick sheets. Put them in a container and heat them to 70°C for steaming. After 10 minutes, put it into a hot-spray autoclave for fiber separation. The pressure is 0.1Mpa, the temperature is 230°C, and the time is 15 minutes. mm, drying ...

Embodiment 2

[0040] Select the silver new poplar species, and use mechanical cuttings on the narrow row slope with alternating wide and narrow rows. The width of the wide row is 0.8m, and the width of the narrow row is 0.5m. 2800 trees are planted per mu, and the density and plant spacing are 40mm. Drip irrigation is carried out between narrow rows, and the amount of irrigation water is kept at 60% of the soil water holding capacity. When the rainfall is sufficient, the irrigation is performed 8 times a year. Weeding with herbicides, chasing urea in June and July, 30kg per mu. After emergence, pick the side buds and keep growing on a single pole. Harvest the strips one year later. After cutting the strips, peel them and cut them into 3cm long, 2.5cm wide, and 0.2cm thick sheets. Put them in a container and heat them to 70°C for steaming. After 12 minutes, put it into a hot-spray autoclave for fiber separation. The pressure is 0.15Mpa, the temperature is 200°C, and the time is 18 minutes. ...

Embodiment 3

[0042] Select tetraploid Robinia pseudoacacia species, and artificially plant seedlings on narrow row slopes with alternating wide and narrow rows. The width of the wide row is 1.0m, and the width of the narrow row is 0.6m. 3500 trees are planted per mu with a spacing of 30mm. Furrow irrigation is carried out in narrow rows, and the amount of irrigation water is kept at 75% of the water holding capacity of the soil. It is properly irrigated when the rainfall is sufficient, and it is irrigated 13 times a year in arid areas. Weeding with herbicides, topdressing with biological fertilizer and urea in June and July, 1kg and 25kg respectively. After emergence, pick the side buds and keep growing on a single pole. Harvest the strips one year later. After cutting the strips, peel them and cut them into 3cm long, 2.5cm wide, and 0.2cm thick sheets. Put them in a container and heat them to 70°C for steaming. After 15 minutes, put it into the thermal spray press bar for fiber separation...

Abstract

The artificial board producing process incldues planting broad-leaved wood through cuttage, irrigation, weeding fertilization and eliminating side sprouts; cutting; peeling, slicing, steaming, fiber separation in pressurized heating reactor, pulping, stoving, mixing with non-toxic adhesive and wax, and molding. The present invention provides new source of artificial board material and is favorable to protecting forest resource.

Description

(1) Technical field: [0001] The invention relates to a method for producing man-made boards by hot-spraying fibers of 1-5-year-old broad-leaved tree strips in an ultra-short cycle, which belongs to the man-made board processing technology. (two) background technology: [0002] At present, wood-based panels at home and abroad are widely used. Most of the industrial materials such as home decoration, construction, and transportation are leftovers after wood processing and residues after harvesting, so that the wood can be comprehensively utilized, but this kind of raw material must be fully used. The disadvantage is that the sources of raw materials are scattered, the varieties are mixed, and the processing plants have to receive and transport the goods in forest areas hundreds of miles away. The implementation of the project has reduced the amount of wood harvested, and the source of raw materials is facing a serious shortage. At present, the types of wood-based panels produc...
