The manufacturing method comprises the steps of rotationally cutting scrap edge environment-friendly wood materials into 2mm-5mm veneers and drying the veneers; gluing an upper-layer panel, a lower-layer panel and a middle-layer panel, pressing the upper-layer panel, the lower-layer panel and the middle-layer panel into a composite plate, sawing the composite plate into plate strips in the same specification, and repeating a gluing process; putting core materials among three layers of transverse-grain balance tension plates, pressing to form multi-layer plates and manufacturing into wide wood strips after conditioning for balance; putting the wide wood strips into an automatic plate splicing machine to form multi-layer plates and sanding into fixed thickness; pressing middle-density plates and the multi-layer plates to form a solid wood composite plate, cutting the solid wood composite plate into plates with specified shapes, standing and conditioning for balance, cutting off four edges, sanding into fixed thickness, and then carving, milling the shape, milling the wire and decorating the surface to form a high-strength anti-deformation composite door plate.
Description
Technical field
type of the present invention relates to a kind of production technology of anti-deformation solid wood composite door, particularly relates to low-carbon (LC), green, environmental protection and energy saving anti-deformation solid wood composite door process for making and structure.
Background technology
along with the develop rapidly of global economy, improving constantly of people's living standard, human consumption's demand and desire are also in immoderate growth, bring huge pressure virtually also to our earth, global warming, the discharge capacity of carbon dioxide grows with each passing day, so it is the much-talked-about topic that the whole world is paid close attention to that the mankind enter low-carbon environment-friendly life.Expert points out that core that low-carbon economy develops is low emission, high-selenium corn and " carbon continues ", and the forest reserves will play important effect and profound significance to this, its for realizing the low emission of greenhouse gases, high-selenium corn is significant.Therefore, strengthen the scientific and reasonable utilization of forestry most important to development low-carbon economy, this also has higher requirement to forest product industry.As the important component part of forest product industry, furniture timber industry is also in a kind of low carbon development mode choosing the links such as operation, use from raw material of searching.Along with the raising of people's living standard, the mankind are also growing with each passing day for the demand of wood-based product's top grade, but are faced with the predicament reduced year by year due to the former forest reserves of China, and Caiyu is lacked of proper care, and causes wood supply amount very in short supply.As everyone knows, forest-tree has absorbing carbon dioxide, releasing oxygen, the effect purified air, timber resources is not inexhaustible, nexhaustible resource, and therefore national correlation department pays much attention to the problem of saving timber resources, has put into effect felling work or even multi-line regression model that relevant laws and regulations policy strictly limits timber, so timber resources has occurred that demand is large, the problem that cost is high.
but by the rapid-result woods of artificial growth as: the Chinese parasol tree tree of limit, road willow and every place of the village, paulownia now become a useful person, but people often use it for rudimentary purposes, not as fuel combustion, be made into glued board, use it for the single use such as external packing, building template exactly, utilization rate is extremely low, wastes the resource of timber greatly.
composite gate is of a great variety in the market, but mostly adopts famous and precious timber, does not have good solution to the wasting of resources, high, the moistureproof deform-proof ability of cost etc.
Summary of the invention
the rapid-result woods that the present invention is directed to artificial growth is as rudimentary purposes, not as fuel combustion, be made into glued board, use it for external packing exactly, the single use such as building template, utilization rate is extremely low, waste the problem of the resource of timber greatly, for secondary veneer, three grades of veneers, because of became uneven, color exception, scab too much, problem not environmentally, I company research staff takes the lead in having broken through this technical barrier with unique structure through studying the scientific and reasonable fabrication techniques process of repetition test for many years. thus not only make use of the remaining secondary veneer of rapid-result woods and veneer factory of artificial growth, three grades of veneer waste woods, make it turn waste into wealth, also greatly reduce cost, expand market, improve the competitiveness of product, a large amount of timber forest reserves are saved, protect ecological environment, positive contribution has been made for creating " low-carbon economy " and " low-carbon (LC) life ".
