Abstract
The invention relates to a method for reducing density and enhancing bamboo stability by hole drilling. According to the method, a gang drill is employed to perform hole drilling on a bamboo strip with four roughly planed sides, the hole diameter is less than 5mm, and the hole spacing is 2-5 times of the hole diameter, and the larger the hole diameter is, the larger the hole spacing is. For holes with a hole diameter of 4-5mm, the hole spacing is 4-5 times of the hole diameter, and for holes with a hole diameter of 2-3mm, the hole spacing is 2-3 times of the hole diameter. The angle between the hole drilling direction and a bamboo strip broadside normal is 0-35 degrees. The drilled holes can be through holes or closed holes, however the through holes are not adjacent, and adjacent holes are not in a same bamboo fiber direction. When the angle is increasingly close to 35 degrees, the diameter of the employed drilling head can be larger, thus avoiding fracture of the drilling head. During drilling, the bamboo strip inclines and locates in the width direction, and the length direction of the bamboo strip is parallel to the cross beam of the gang drill. The method provided by the invention reduces the bamboo product density, enhances the dimensional stability during use, significantly improves the corrosion prevention, mold prevention, water resistance, weatherability and other improvement treatment effects and efficiency of bamboo products, and provides raw materials for development of bamboo outdoor products.
Description
Technical field
The present invention relates to the method that boring method reduces density and improves bamboo wood stability, belong to handicraft and manufacture field.
Background technology
A little less than the anti-corruption of existing bamboo matter furniture, Antimould power, water-proof climate resisting ability, conventionally can only be in indoor use, with regard to its basic reason, be that the raw material of manufacturing bamboo matter furniture does not possess enough anti-corruption, anti-mildew, waterproof, weather-proof ability, and it is a lot of bamboo wood to be carried out to the Upgradings such as anticorrosive mildewproof, cost is high, practical effect is not good enough out of doors, architectural feature due to bamboo wood, modifying agent is to it radially or a little less than tangential penetrating power, and osmotic effect is relatively better longitudinally, but longitudinal length is too large, and actual improved effect is poor.
On the other hand with, existing bamboo material density is high, as the furniture weight of manufacturing with bamboo glulam, special child and old man go mobile bamboo furniture inconvenient, and bamboo furniture mostly there will be distortion after in a year or so, and the bamboo wood poor stability of manufacture furniture be described.
For solving above-mentioned many-sided problem, technical scheme of the present invention has been proposed.
Summary of the invention
The present invention relates to the method that boring method reduces density and improves bamboo wood stability, in the situation that substantially not affecting product mechanical property, reduce the density of bamboo matter product, improve the dimensional stability of its use procedure, significantly improve improved treatment effect and the efficiency such as anticorrosive mildewproof water-proof climate resisting of bamboo matter product, for the exploitation of bamboo matter outdoor products provides raw material.
The invention provides a kind of method that boring method reduces density and improves bamboo wood stability, it comprises the steps:
One: adopt gang drill to hole to the bamboo cane after the force plane of four sides, aperture is less than 5 millimeters, pitch-row is aperture 2-5 times, the larger pitch-row of bore dia is larger, and as the hole that aperture is 4-5 millimeters, pitch-row should be 4-5 times of aperture, aperture is the hole of 2-3 millimeters, pitch-row is aperture 2-3 times;
Two: the angle of wide normal of boring direction and bamboo cane is 0-35 degree, and boring can be through hole or closed pore, but non-conterminous between through hole, and adjacent hole is not in same bamboo fiber direction.When above-mentioned angle more approaches 35 while spending, the bit diameter of employing should be larger, in order to avoid broken drill.During drilling, bamboo cane tilts and location at width, and bamboo cane length direction is parallel with the crossbeam of gang drill.
Three: simultaneously drilling in bamboo cane of aperture, with the large aperture of different pore size, apart from one another by, the mean value that distance is separately step 1, but in same bamboo cane, only beat the hole being parallel to each other.
The specific embodiment
Hereinafter, now the present invention will be described more fully.Yet the present invention can implement in many different forms, and should not be interpreted as being confined to embodiment set forth herein.On the contrary, it will be thorough with completely providing these embodiment to make the disclosure, and scope of the present invention is conveyed to those skilled in the art fully.
The invention provides a kind of method that boring method reduces density and improves bamboo wood stability, it comprises the steps:
One: adopt gang drill to hole to the bamboo cane after the force plane of four sides, aperture is less than 5 millimeters, pitch-row is aperture 2-5 times, the larger pitch-row of bore dia is larger, and as the hole that aperture is 4-5 millimeters, pitch-row should be 4-5 times of aperture, aperture is the hole of 2-3 millimeters, pitch-row is aperture 2-3 times;
Two: the angle of wide normal of boring direction and bamboo cane is 0-35 degree, and boring can be through hole or closed pore, but non-conterminous between through hole, and adjacent hole is not in same bamboo fiber direction.When above-mentioned angle more approaches 35 while spending, the bit diameter of employing should be larger, in order to avoid broken drill.During drilling, bamboo cane tilts and location at width, and bamboo cane length direction is parallel with the crossbeam of gang drill.
Three: aperture drilling in bamboo cane simultaneously, with the large aperture of different pore size apart from one another by, distance is separately the mean value of step 1, if: the diameter in a hole is 5mm and words that the diameter of adjacent holes is 2mm, their distance is (5 * 5+2 * 2)/2=14.5mm, but only beats the hole being parallel to each other in same bamboo cane.
The present invention has following technique effect:
Reduce the density of bamboo glulam (to 590-680kg/m
3),
Improve the stability (raising amount 50%-70%) of bamboo glulam
Improve the rate of drying (raising amount 55% one 86%) of bamboo wood
Improve the improved treatment effects such as anticorrosive mildewproof water-proof climate resisting and the efficiency (different modifying agent increase rates are different, and one is between 18%-75%) of bamboo wood.
The angle of wide normal of boring direction and bamboo cane is larger, as approaches 35 degree, and the slotted eye in wide of bamboo cane is fewer apart from quantity larger, hole, but boring bamboo wood density reduction is substantially constant afterwards.
The foregoing is only embodiments of the invention, be not limited to the present invention.The present invention can have various suitable changes and variation.All any modifications of doing within the spirit and principles in the present invention, be equal to replacement, improvement etc., within protection scope of the present invention all should be included in.
