Description
Technical field
The utility model relates to a kind of woodwork plate, and specifically, relating to a kind of utilization does not have the gluing technology of closing and make environmental protection China fir core-board.
Background technology
China fir (Cunninghamia lanceolata) is Chinese distinctive seeds, be to adapt to the important speed of coordinating mutually with Hunan Province's environment facies to give birth to the public welfare forest seeds of ecological safety, in Shaanxi, all there are distribution in provinces such as Henan, Anhui, Jiangsu, Zhejiang, Fujian, Jiangxi, Sichuan, Chongqing, Guangdong, Guangxi, Yunnan.China fir is the primary merchantable timber of southern china, can be widely used in building, bridge, electric pole, door and window, furniture, plate, woodenware etc.But building material such as metal, plastics has progressively replaced the application of timber within a short period of time, causes the rapid atrophy of the China fir material scope of application, and demand falls sharply, and particularly the tending and intermittent cutting of forest small dimension wood does not almost have utilization, has occurred unsalable and a large amount of phenomenons that overstock.For a long time, the working dynamics of aspects such as exploitation China fir industrialization plate product is not enough, and this has become nationwide problem.The timber extract is a small amount of component that has magical characteristic in the timber, although amount is few, function is peculiar, particularly bleachinges and dyeing at timber, has material impact aspect the gummed, improvement such as anticorrosion, fire-retardant.Therefore especially the comprehensive study of high value added utilization is extremely urgent to carry out the China fir processing and utilization, to excavate the natural potentiality of China fir, give full play to the China fir health care, improve China fir added value, support Hunan Province's forestry sustainable development, promote Hunan Province's timber industry core competitiveness, set up China fir high-quality and high-efficiency New Machining Technology system and have important theoretical and realistic meaning.
China fir is Chinese distinctive seeds, also is the seeds of southern china afforestation area maximum, existing at present lanceolata forest more than 600 ten thousand ha, total accumulation 2.4 hundred million m
3Wherein artificial pure forest 1,200,000 ha, total accumulation 7,000 ten thousand m
3, the accumulation of many mature forests can reach 7m for every mu
3The masson pine of China fir and China, larch, Chinese pine, no matter willow and compare by artificial pure forests such as trees is afforestation area, total accumulation, or the accumulation of every mu in mature forest, all comes out at the top.The China fir growth is fast, and disease and pest is few, and form is perfectly straight satisfactory, and material is light and tough, easily processing, color and luster beautiful texture, sheet material are not yielding warps and fractures, and special aroma is arranged, anti-moth corrosion resistant is rare good indigenous tree, can extensively use building, furniture, bridge, boats and ships, papermaking etc.But compare with the hard broadleaf, the China fir material is relatively poor, short texture, and intensity, hardness are low, not wear-resisting, easily moisture absorption, the size instability, practical application is few, promptly accounts for 20%～25% China fir of Chinese commodity material, does not obtain so far reasonably effectively utilizing.Through the further investigation of domestic scholars to the China fir processing and utilization, China fir utilizes technology increasingly mature aspects such as particieboard, core-board, and the high-quality utilization of China fir still is in the key stage, along with development of market economy, the timber price of China fir glides, and requires the research cry day of high value added utilization lanceolata forest to contain.
The character of wood structure, physics, mechanics and chemistry is the basis of China fir processing and utilization, need give special attention, and Cai Zemo has studied the difference of China fir diametric plane chord face mechanical property; Bao Fucheng etc. have inquired into the correlation Changing Pattern between wood structure and the wood staining effect, subsequent analysis the relation of China fir and masson pine permeability and fine structure, the change mechanism of the China fir surface characteristic of treatment of different temperature is also inquired into.Ren Haiqing etc. the have used electron microscopic observation deface under China fir, masson pine band tension, rift grain tension and the impact loading; The char yield and the thermokinetic parameters in phenols fire retardant processing China fir each stage of pyrolytic process that Hu Yunchu etc. have adopted the TG-DTA technical research; Employing organic element analysises such as Qin Tefu, infrared spectrum, proton nuclear magnetic resonance spectroscopy are to studying from the chemical functional group and the chemical bond feature of China fir juvenile wood and mature wood milled wood lignin quality; Jiang Zehui etc. utilize analysis of neural network wood internal structure parameter to determine its physical mechanics feature.Sun Lingfeng etc. think that the Chinese fir root-bark essential oil contains α firpene, citrene, p-cymene, α terpinol, α cedrene, α Calamus alkene and β elemene etc.; Zhou Xiongzun etc. have studied the chemical composition of the green copestone oil of China fir ether extract, for its comprehensive benefit provides scientific basis; Contain many beneficiating ingredients in the volatile matter of the test confirmation China fir of Sun Qixiang etc., especially various terpenoids, have good physiologically active and aromatotherapy effect mostly, as can be antibiotic, anti-inflammatory, eliminate the phlegm, antibechic, and remove psychological anxiety with tired, make us feeling nature, light, comfortable, happiness etc., thereby have the air quality of improvement, promote the able-bodied function of human body; Sun Qixiang points out that also the compositions such as terpene volatile matter of bamboo and China fir composite floor are being better than full bamboo floor aspect improvement air quality and the adjusting human body physical and mental health.The member of seminar utilizes GC-MS and GC-FTIR to detect the China fir organic extract and finds, contains the chemical composition that can activate brain cell, promote longevity in the China fir.
This shows that the structure of China fir and character comprehensive study are not carried out as yet.Current, the forest development in Hunan Province is if only have papermaking, the wood-based plate of the low output value to use material as its major product, and can't replenished aspect the decoration of Peak output, the furniture woods, the delayed effect of development of Hunan Province's forestry, self-employed tree cultivator's income increase, to be restricted, decoration, furniture industry also can be very limited with the scope of material.
The research of China fir high value-added industries is the key of artificial forest China fir processing and utilization, it is the strong guarantee that improves the China fir product quality, being the reliable method that effectively utilizes China fir, significantly improves its commercial value, is the technical guarantee that realizes Hunan Province's Chinese Fir Plantation woods sustainable development.The source of raw material is thirsted for by enterprise, thirsts for China fir new technology, new technology, new product more, and the research of therefore carrying out this respect is extremely urgent, and meaning is very great.
Applicant of the present utility model produces technology to the China fir core-board and studies, and finds its energy-conserving and environment-protective manufacturing technology.
