Abstract
A method for pre-processing of bamboo used for plywood comprising: a green bamboo 2 is cut to a predetermined length so that each cut part has a plurality of nodes 3, a plurality of cutouts 5 are longitudinally formed at a predetermined peripheral intervals (w) by a saw in a peripheral wall 4 of the cut green bamboo 2; next, the green bamboo 2 is boiled by water and naturally dried. After that, the nodes of the bamboo 2 are removed, and the bamboo 2 is divided into a predetermined number of split materials 14. The split material 14 is processed into a plate material. This method is to prevent occurrence of torsion and warpage during pretreatment, such as mothproofing, of a green bamboo to obtain a plate material at a high yield.
Description
The present invention relates to be applicable to the glued board of construction materials such as mould material, specifically, relate to the preprocess method of the bamboo wood that is used for glued board, so that make slice, with stacked, the bonding making bamboo plywood of slice by thick abundant Meng Zongzhu etc.
Mould material generally is to use the glued board of lauan, but owing to the demand to this glued board rapidly increases, exists the danger that causes that the forest reserves are exhausted rapidly and earth environment is destroyed, and therefore, presses for protection and rationally utilizes the forest reserves.
Bamboo and trees relatively, but have in the short time produce again (about 3 years promptly ripe), plantation and subsequent management easily, advantage such as durability, impact strength be big, yet present case is that bamboo, especially the Meng, the ancestor bamboo was utilized as yet well.
And to utilize the bamboo wood material to make glued board, need remove the insect protected such as sugar that contain in the bamboo, anti-rotten the processing.If this carries out insect protected, anti-rotten the processing after former bamboo is sawn into slice, then because slice can be distorted or warpage etc., processing causes difficulty to plate.And, with flaggy is folded make glued board after, still exist the problem that warpage can take place after a period of time of placing.
The objective of the invention is to, in view of the above problems, provide a kind of preprocess method that is used for the bamboo wood of glued board, with generation, the high sheet material of acquisition effective rate of utilization of distortion or warpage in the preprocessing process such as insect protected that are suppressed at former bamboo.
For achieving the above object, the specific length with a plurality of joint films is cut into former bamboo in the present invention system, with the circumferential interval of stipulating a plurality of longitudinal cuts are set at the bamboo wall part of the former bamboo of cutting off with saw, use the former bamboo of water boil again, air dry then, remove the joint film in the former bamboo, be separated into the slice of specified quantity, slice is carried out plate processing.
According to the present invention, at the bamboo wall part of the former bamboo with specific length a plurality of longitudinal cuts are set, each slice of being cut apart by otch is carried out preliminary treatment such as desugar, insect protected, drying under the state that keeps connecting by the joint film.Thus, can prevent slice distortion or warpage, it is easy that preliminary treatment also becomes.
After former bamboo drying, be preferably in to face and carry out the plate first being processed and remove the joint film, slice is disconnected from each other.With the disc revolving cutter similar the slice surfaces externally and internally is processed, made it smooth and parallel, again two sides are processed, make its smooth and width that have regulation to face cutter.Because slice is not distorted and warpage, therefore, can carry out the plate processing uniform, that effective rate of utilization is high.
Fig. 1 is the plan cross-sectional view of former bamboo, and Fig. 2 serves as reasons and cuts apart the stereogram of the slice that former bamboo forms, and Fig. 3 is the plan cross-sectional view of the sheet material that made by slice, and Fig. 4 is for by the former bamboo artwork of making sheet material.The present invention system makes sheet material by former bamboo through technology as shown in Figure 4.At first, with former bamboo 2 be cut into specific length (1～2m), the overall length of former bamboo 2 with saw in the part of bamboo wall 4 with the circumferential interval w of regulation (about 30～40mm), towards axle center O direction a plurality of otch 5 are set.The degree of depth c of otch 5 is darker than the wall thickness t of bamboo wall 4, and is more shallow than the radius r of former bamboo 2.Former bamboo 2 through above-mentioned processing has a plurality of otch 5, and holds its shape by a plurality of joint films 3, therefore, can not place be distorted after a period of time, distortion such as warpage.
Then, the former bamboo 2 that will have otch 5 was boiled about 1 hour, removed (pentosan and lipid components) such as sugars in the bamboo, carried out insect-prevention treatment.Again as required, impregnated in the suitable soups such as insect protected liquid, impregnating fluid, lubricating fluid or impregnability reactive resin liquid.
Again will be through above-mentioned pretreated former about 1 week of bamboo 2 air dries.Then, former bamboo 2 is moved in the hothouse, drying is about 24 hours under about 100～150 ℃ temperature, makes dimensionally stableization and the weight reduction of former bamboo 2.Take out former bamboo 2 from hothouse then, cooling is about 24 hours naturally.
At last,, remove joint film 3, each bamboo wall 4 is separated, become slice by shoot methods such as removing joint film rod in the hollow interior of former bamboo 2.
As shown in Figure 3, at first use the disc revolving cutter similar that the slice 14 that makes is as stated above processed, mill out smooth and parallel inner surface 24a and outer surface 24b, then to face cutter, mill out smooth two sides 24c, make the sheet material 24 of prescribed level.Sheet material 24 is stacked, bonding with adhesive, be processed into bamboo plywood.
The present invention as mentioned above, former bamboo is cut into the specific length with a plurality of joint films in system, with the circumferential interval of stipulating a plurality of longitudinal cuts are set at the bamboo wall part of the former bamboo of cutting off with saw, use the former bamboo of water boil then, then, the joint film in the former bamboo is removed in air dry again, be separated into the slice of defined amount, and slice is processed into plate.Because before the former bamboo one-tenth slice by specific length, the former bamboo of original shape state unseparated to slice, that connected mutually by the joint film has carried out preliminary treatment such as desugar, insect protected, therefore, can keep dimensionally stable, prevent distortion such as slice distortion, warpage.
Add man-hour in that slice is carried out plate,, slice is separated with the state of dimensionally stable as long as will remove through the joint film of pretreated former bamboo, can carry out dimensionally stable, the effective rate of utilization height promptly not have the plate of waste to process.
Fig. 1 is the former bamboo planar cross-sectional of the preprocess method of the bamboo wood that is used to illustrate that glued board of the present invention is used.
Fig. 2 is a stereogram of cutting apart the slice that former bamboo forms.
Fig. 3 is the plan cross-sectional view of the sheet material that made by slice.
