Description

A kind of poplar Scrimber and preparation method thereof
Technical field
The present invention relates to timber wood-based plate plywood technical field, particularly relate to a kind of poplar Scrimber and preparation method thereof.
Background technology
China's Forest Resources is poor, and wood supply is nervous.Along with the development of science and technology, timber recombinant technique receives country's great attention.The most domestic production technology that has been developed for, and apply for a patent, employing fast-growing woods is raw material, after multiple physics processes with chemical technology, can effectively change wood performance, change it wooden soft, the defects such as density is little, easy deformation, making its density increase, intensity increases, water resistance, antiseptic property, dimensional stability is significantly improved, this technique can effectively save timber resources, forms recycling of fast-growing woods, improves the service efficiency of timber.
Scrimber is on the premise of not upsetting lumber fibre orientation, retaining timber fundamental characteristics, timber material is rolled into " wood bundle " modifying composition again, make a kind of intensity height, specification is big, have the novel timber of natural wood texture structure, can substitute for solid wood hardwood completely, its performance is better than solid wood hardwood.
Along with the raising of living standards of the people, the requirement for house fitting-up is more and more higher, selects the consumer group of solid wood day by day to rise, but the solid wood hardwood of Tropical rain forest is faced with the edge of scarcity.Australia started just research Scrimber technology from 1973, wants to work out the wood that can substitute solid wood hardwood, can not produce in enormous quantities on a production line always.
China begins one's study Scrimber technology for 1976, and the nineties, " Scrimber science and technology " was put among country's " 95 program for tackling key problems in science and technology ".Until 2013, existing company of China have developed Scrimber technological process, and has applied for national patent, can high-volume produce on a production line.Scrimber can compare favourably with natural hard solid wood, and intensity is higher than redwood, and anticorrosion is waterproof, can be widely applied to solid wood door and window, indoor and outdoor furniture, garden feature, the making of hydrophilic plank road floor and Wood engraving；Can simultaneously serve as modified hard solid wood and realize outlet, expand the export abroad of China's forestry products.Patents company will develop multi-layer solid wood building system further, and using Scrimber base material as the structural material of roof truss, combine the maintenance materials as body of wall with heat-insulating and noise-insulating material, form low-carbon environment-friendly, the modern multi-layer wooden structure building system of green energy conservation.
Founding laboratory in colleges and universities's result of the test from maine state of U.S.A to learn, Scrimber performance is poor unlike armored concrete, and even some aspect is also better than armored concrete.University of Maine completes the construction of the first in the world seat Scrimber ocean harbour in nineteen ninety-five, this ocean harbour is located in Maine State Ba Ergang, long terminal 124 feet (about 37.8 m), use restructuring timber, while steel harbour cost low 25%, the anti-pressure ability of bridge itself fullys meet performance and the level of steel reinforced concrete building materials.In the future, replacement solid wood hardwood even armored concrete is applied to daily house fitting-up by Scrimber, and yoke builds in making.For protecting the tropical forest, solid wood hardwood forest contribution the biggest.Scrimber formaldehyde is E0 rank, and environmental protection is harmless.
Owing to aspen fibers by using silicon short texture, material are relatively poor, its range of application is subject to bigger restriction, is currently mainly used as solid wooden compound floor central layer, building template, base plate, short-cycle industrial material material or road, river course green tree species.The timber that northern China is conventional, its matter is soft, and property is steady, cheap and easy to get.Often use on ancient furniture as the attached material of elm furniture and the tire bone of lacquer furniture.This is described poplar also known as " PopulussimoniiCarr. ", often has the gloss as cross-talk, therefore also known as " satin poplar ", is not the just that Soviet Union poplar of introduction, Populus lasiocarpa Oliv., Populus euphratica etc. in this century.Poplar often has " disturbing taste ", more light and soft than birch.Birch then has micro-perfume (or spice), often has superfine memnonious immersion lines.This is the difference of the two.Along with social city, the development of technicalization, universal along with humanity concept, and the composition of novel harmonious society, design that a kind of intensity is high, be difficult to deformation, anti-corrosive properties are excellent, water-tolerant and fire-retardant poplar Scrimber are critically important.
