Abstract

The utility model relates to a crop stalk hollow flakeboard which comprises wood shavings and crop stalks processed with squashing, drying, filtering and extrusion molding, the thickness of the hollow board is from 20 mm to 40 mm, hollow through holes evenly arrayed inside the board core with the hole diameter of 15 mm to 35 mm, hole interval of 2 mm to 8 mm, the distance of the through hole to the surface of the board is 2 mm to 8 mm, the hollow board not only achieves small specific density, saved material, heat insulating, great sound proof effect, high intensity, high impact resistance and low water absorbing thickness and expanding ratio, but also saves great precious timber resource, protects the environment and pioneers the industrial application foreground of the synthesized utilization of the stalks and contributes significantly to the countryside economy development and increasing farmer income. The board is the good product to update the man-made plate with great economic and market value.

Description

The agricultural crop straw hollow chipboard

Affiliated technical field

The utility model relates to a kind of cored slab, especially a kind of agricultural crop straw hollow chipboard.

Background technology

At present, artificial hollow chipboard is widely used with the advantage of its uniqueness, and its light weight is inexpensive, heat-insulating sound-insulating, it not only has all advantages of natural lumber, and some aspect more is better than wood based panel, still, shortage along with the worldwide forest reserves, the production of timber wood-based plate has been subjected to very big influence, and the demand of wood-based plate is increasing year by year, therefore, joint wood generation wood and imperative for art with grass is quite necessary.

Summary of the invention

For the problem that solves present joint wood generation wood and save timber with grass generation wood, the utility model provides a kind of agricultural crop straw hollow chipboard, this particieboard, not only proportion is little, materials are economized, heat insulation, soundproof effect is good especially, it is the intensity height also, shock resistance is strong, and water sucting thickness and expansion rate are all extremely low; And it can save the timber resources of a large amount of preciousnesses; can preserve the ecological environment; opened up the application prospect of industrialization for the comprehensive utilization of stalk; to promoting development of rural economy, increase peasant's income; all be significant; this plate is the good product that present wood-based plate updates, and has huge economy and market value.

The concrete scheme that its technical problem that solves the utility model adopts is: this crops hollow chipboard is to have through hole in the middle of this plate core, it is characterized in that: the thickness a of this cored slab is 20mm～40mm, in the plate core, evenly distributedly have a hollow through hole, aperture d is 15mm～35mm, pitch of holes c is 2mm～8mm, and through hole is 2mm～8mm to the distance b of plate surface.

Its beneficial effect is: this particieboard, not only proportion is little, materials are economized, heat insulation, soundproof effect is good especially, it is the intensity height also, shock resistance is strong, water sucting thickness and expansion rate are all extremely low; And it can save the timber resources of a large amount of preciousnesses; can preserve the ecological environment; opened up the application prospect of industrialization for the comprehensive utilization of stalk; to promoting development of rural economy, increase peasant's income; all be significant; this plate is the good product that present wood-based plate updates, and has huge economy and market value.

Description of drawings

The utility model is described in further detail below in conjunction with drawings and Examples;

Accompanying drawing is a structural representation of the present utility model;

Among the figure: 1. through hole, 2. plate body, 3. plate core, a. thickness of slab, the b. through hole to the plate identity distance from, c. pitch of holes, d. aperture.

The specific embodiment

(1). select materials: select the furniture leftover pieces of high-quality meaning poplar earlier for use, through the shaving machine wood shavings, the hammer crushing crusher machine selects agricultural crop straw again, cuts into short material, and its length is 8mm～35mm, together sends into the cylindrical drier drying, and its stalk consumption is 80%;

(2). drying: send into the cylindrical drier drying: the inlet temperature of control drying machine is: 120 ℃, outlet temperature is: 55C, washing shrinkage after drying is: 6mm%;

(3), screening: dry back particle enters vibratory sieve, removes aniseed with the sieve aperture net of 8mm * 9mm, removes particle with the sieve aperture net of 1mm * 1mm; Wood shavings and stalk form length after screening are: 14mm～35mm, and width is: the particle of 2mm～8mm, thickness is: 1mm～3mm reaches and accounts for 73% of total amount; Length is: 8mm～13mm, and width is: 0.5mm～1.5mm, its thickness is: reaching of 0.6～1mm accounts for 27% of total amount;

(4). applying glue: adopt spiral sizing applicator, according to oven dry material and 100: 4 ratio applying glue of hard resin, other adds 0.7% paraffin water repellent and weak acid curing agent, and the control aridity is 2 hours;

(5). extrusion modling: with the patent No. is the extruding of 2005100953357 press, the unit pressure operation evenly, the blanking amount is consistent with slab thickness, the slab thickness of present embodiment is 33mm, pushing ejecting plate speed is the 55cm/ branch.

Claims

1. agricultural crop straw hollow chipboard, this particieboard is to have through hole in the plate core; It is characterized in that: the thickness a of this particieboard is 20mm～40mm, in the plate core, evenly distributedly has a hollow through hole, and aperture d is 15mm～35mm, and pitch of holes c is 2mm～8mm, and through hole is 2mm～8mm to the distance b of plate surface.
