The bamboo strips are longitudinally distributed in the wood wool along the chipboard and every two bamboo strips are arranged certain space. Both the surfaces of bamboo strips and the wooden abatement are painted with adhesive. The bamboo strips are paralleled and linearly distributed in the chipboard and surf green is facing to upper and lower external surface of the neighboring chipboard. The bamboo strips enhancement chipboard can include four layers bamboo strips, which are respectively close to the wider upper and lower surface of the chipboard. The bamboo strips of the neighboring layers are staggered and symmetrically arranged to chipboard width direction. The bamboo strip has the same length with the abatement. The wooden abatement with adhesive on the surface is alternative arranged among the bamboo strips and forms traversing connection. The bamboo strips enhancement chipboard can completely utilize artificial wood and enhance 3-5 times of the chipboard directional (longitudinal) mechanics strength, and reduce 2 times of linear expansion. The utility model can successfully satisfy the property requirements of building trades, container bottom board and compartment board with characteristics of high product intensity, low cost and simple processing art.
Description
Technical field
The utility model relates to a kind of bamboo bar that can be widely used as building structural materials, container bottom board and compartment board etc. and strengthens particieboard.
Technical background
Because the China's timber scarcity of resources, the application of solid wood is restricted.Therefore utilizing artificial forest wood and branch thereof and residue to make particieboard is the effective way of alleviating China's timber shortage.In the past, China's wooden shavings plate was mainly used in non-structural materials such as furniture manufacturing and finishing.In recent years, because the needs of economic construction, the structure that is used to build with carrier increases with the particieboard requirement.Yet, because the artificial tree material particle board exists intensity and the low shortcoming of modulus, influenced its use as engineering material.China is bamboo big country, and no matter cultivated area still is an accumulation is all occupied first place in the world.Bamboo growth is fast, and 3-5 can become a useful person, and bamboo wood compares with timber and have the intensity height, and hardness is big, and the characteristics that dimensional stability is good, particularly surf green part, its intensity are than the high 2-3 of common wood doubly.Therefore, utilizing bamboo wood to improve the physical and mechanical property of existing particieboard, is the effective ways that make full use of China's characteristic resources.
For mechanical property and the expansion purposes scope that improves particieboard, adapt to the needs in building and engineering material market, develop the wooden shavings directional technology abroad and produced oriented wood chipboard (OSB), make the longitudinal strength of plank be improved 1.5-2 doubly.Because the product that utilizes this technology to produce has made full use of undersized log, the glued board that can replace consuming big footpath level log uses, and has saved raw material greatly.Therefore, in North America and Europe extensive use.China also has similar techniques to occur and this type of launch products, but because aspects such as process equipment and markets, fail large tracts of land to promote, and the intensity increase rate of this product is limited.At present, utilize the way of the surperficial veneer of high-intensity inorganic material (glass fabric) to improve the intensity of plank in addition, yet the bonding strength of the combination interface of inorganic material and organic material is a weak link, causes its resistance to ag(e)ing poor.In recent years, utilize bamboo material stacked material to be attached to the technology that wooden shavings plate upper and lower surface strengthens plank intensity and occur, its intensity is very high, but because the processing volume recovery of bamboo material stacked material is lower, causes this technical products processing cost higher.There is the intensity height in the product that utilizes impregnating glue of veneer plasticizing post-facing to strengthen the particieboard performance, the problem that cost is also high equally.
The utility model content
The purpose of this utility model provides and a kind of bamboo wood (bar) is placed wooden shavings as reinforcement, and the composite bending modulus bamboo bar good, that save bamboo material that strengthens by rational structure configuration and gummed processing well-thought-out plan bar strengthens particieboard.
The utility model is achieved in that
A kind of bamboo bar strengthens particieboard, and it is made up of bamboo bar, wood particle; The bamboo bar vertically is distributed in the wooden shavings along particieboard, has certain interval between the bamboo bar; The surface of bamboo bar, wood particle all scribbles adhesive.
Described bamboo bar strengthens particieboard, and the bamboo bar can be row shape is parallel and is distributed in the particieboard, and surf green is towards the particieboard that closes on outer surface up and down.
Described bamboo bar strengthens particieboard, and it can have four layers of bamboo bar, respectively near two surfaces up and down of particieboard broad, staggers between the close two-layer bamboo bar and in the configuration symmetry of particieboard thickness direction; The length of bamboo bar is identical with the length of wood shavings; The wooden shavings of surface coating is interspersed between the bamboo bar, forms horizontal connection.
A kind of bamboo bar strengthens particieboard, and it is made up of bamboo bar, wood particle; The bamboo bar is row's shape parallel longitudinal along particieboard and is distributed in the particieboard, and surf green is outer surface about the particieboard that closes on; Has certain interval between the bamboo bar; Four layers of bamboo bar that they are all are divided into two parts, respectively near two surfaces up and down of particieboard broad, stagger between the close two-layer bamboo bar and in the configuration symmetry of particieboard thickness direction; The surface of bamboo bar, wood particle all scribbles adhesive; The wooden shavings of surface coating is interspersed between the bamboo bar, forms horizontal connection; The length and width of its particieboard, thick 2440mm, 1220mm, the 25mm of being respectively; The length and width of its wood particle, thick 60-100mm, 20-50mm, the 0.3-0.5mm of being respectively; The length and width of bamboo bar, thick 2440mm, 12mm, the 3mm of being respectively; Bamboo bar and wood shavings surface are coated with synvaren of the same race.
The beneficial effects of the utility model:
The utility model utilizes the bamboo bar to strengthen the wooden shavings plate, both can make full use of artificial forest wood, enlarges its purposes, and the characteristic resources advantage that can bring into play China's bamboo wood is arranged.This patent method for designing and manufacturing process technology, owing to adopt the mode of bamboo bar staggered floor configuration, wooden shavings can replace combination, forms wave-like, can improve the inertia distance of material, strengthens bending resistance.The bamboo bar is as reinforcing material, wood shavings and adhesive are as matrix, under the situation that satisfies the transverse strength requirement, orientation (vertically) the mechanical strength 3-5 that generally can improve particieboard doubly, the particieboard that the bamboo bar strengthens in the vertical, promptly its bending strength and modulus improve 3-5 doubly, linear expansion reduces 2 times, transverse strength and other physical index can reach the standard-required of U.S.'s structure with oriented wood chipboard, can better satisfy the performance requirement of building trade and container bottom board and platform floor.The utility model is compared with technology with the method that tradition strengthens particieboard intensity, has product strength height, low, the process implementing characteristic of simple of cost, and has given full play to China's bamboo timber resource and the high-intensity characteristic advantage of bamboo wood.
