Abstract
The utility model discloses plant stem artificial wood relating to the wood-based panel field. The wood provided in the utility mode uses agricultural residues such as cotton stems, castor-oil plant stems, capsicum stems, and hemp stems and so on as raw materials, and adhesive can be coated on the surface of the row materials. The above mentioned stems can be arranged along the length direction of the stems to form a rectangle, and then can be formed by using the hot pressing method in a press. The plant stem artificial wood is characterized in that the wooden parts of the plant stems can be bonded together by using the adhesive to produce directional wooden section bars used for the wood-based structure. The artificial wood provided in the utility model can be used to replace the natural timer widely, and can provide a new product to the wood-based panel industry.
Description
Technical field
The utility model relates to a kind of plant haulm sham wood, belongs to wood-based plate and makes the field.
Background technology
As everyone knows, China is the country of a timber resources serious lack, and per capita rate is well below world standard, and along with the develop rapidly of national economy and improving constantly of living standards of the people, the timber imbalance between supply and demand is growing.In recent years, because a large amount of falling trees constantly reduces area of woods, cause vicious circles such as soil erosion, ecological imbalance thus.According to relevant department's prediction, China's year wood supply deficit is up to ten thousand stere more than 4000 at present.If rely on the comprehensive utilization of direct processing of forest material and residue to be difficult to satisfy the needs of China's rapid growth timber and goods thereof separately.Must transfer to the developing focus of the substitute of timber on the inexhaustible agricultural wastes of China.
In recent years, China's wood-based panel industry obtains develop rapidly, and formed with particieboard, fiberboard, core-board and multi-plywood and timber floor is master's wood-based plate industry at present.These products are in the strong timber shortage situation of having replenished of furniture manufacturing industry.But aspect structure material, do not have than quantum jump so far.Integrated timber, laminated veneer lumber is owing to all being to be raw material with the natural timber, so slowly do not form large-scale production.
China is a large agricultural country, and annual all the generation extremely measured big residue--plant haulm, and like cotton stalk, castor anesthesia stem, Caulis Capsici stalk, stem of eggplant stalk and hemp stalk etc., these plant haulms all have certain wood fibre.Be good imitation wood's raw material., people do not have effective and reasonable the using of this precious resources for a long time.
Summary of the invention
The purpose of the utility model is exactly according to the problems referred to above, and a kind of plant haulm sham wood is provided, and comes alternative structure to use natural timber with this, has both made the plant haulm resource obtain effective and reasonable utilization, plays the effect that protects forest resources and do not cut down from the source again.
The technical scheme of the utility model is: be aggregate with the plant haulm; With plant haulm broken half; And,, be pressed into directed artificial square pillar timber through hot press with the plant haulm that the scribbles binder rectangularity of mating formation that side by side is arranged in parallel along its length at its outer surface brushing binder.
Plant haulm belongs to the discarded object of annual plant, and its stem stalk root diameter (RD) is thicker, and generally between 10mm～20mm, the stem stalk tip is thinner; Generally between 4mm～8mm,, and be the cross section, garden because of the thickness difference of plant haulm itself is bigger; So must plant haulm is broken partly into strips, break into two at least, generally must break into 4 half; This diameter with plant haulm is relevant, and diameter little broken half is few, otherwise broken half is many; Purpose is cross section, decomposition garden, makes strip branch and strip branch thickness approaching as far as possible, that is to say the cross sectional shape that changes plant haulm in this way; Dwindle the raw-material thickness difference of branch,, reduce the decrement of plant haulm in making moulding to obtain the raw material of relatively evener matter.The plant haulm bar that obtains through such processing is not only and is helped blank and in mould, mat formation, but also has reduced density of product, reaches the effect of even matter and surfacing simultaneously, and has reduced the expansion rate of water absorption of product.
The physics of the utility model product, mechanical property approach the timber with density basically; And expansion rate of water absorption is little; The shape that is characterized in this sham wood is that the shape by mould determines; So, can once process various structures as required and use profile and wire, in the timber structure field, can replace natural timber fully.
