Research on Qingdao Guosen Machinery Co., Ltd forest Biomass materials were reprocessed under high temperature and high pressure. Under the premise of not disturbing the arrangement direction of plant fiber and retaining the basic characteristics of biomass, fast-growing tree veneers (poplar veneer, eucalyptus veneer, etc.) were used; Small diameter wood, branch wood, bamboo strip and other low-quality timber are rolled (or rotary cut) into "wood (bamboo) bundles", which are rearranged and combined to form a new type of wood material with high strength, large specification and natural wood texture structure. This new material is called reconstituted wood or reconstituted bamboo. The main equipment for the production of RSM include: production and release equipment, carbonization equipment, drying equipment, pressing equipment and pressing mould, curing equipment, etc. Production equipment, carbonization equipment, drying equipment and curing equipment
Guosen mechanical pressing equipment is a frame type large tonnage hydraulic press, which can quickly close and pressurize, and has multi-step joint operation; The hydraulic system adopts constant power variable pump to reduce the installed power, and the motor adopts variable frequency starting to reduce energy consumption; The electrical control adopts PLC programmable controller and touch screen to display the technological process. The feeder is an automatic feeding device with preloading. Loading and pressing can be carried out at the same time, which saves the time of separate loading and improves the production efficiency.
Physical and mechanical properties: it can produce high-density artificial square wood with the specification of 2500 * 150 * 160, which can be customized according to customer requirements. Its density is more than 1000kg / m ³， The longitudinal static bending strength is more than 80 MPa, the transverse static bending strength is more than 30 MPa, the longitudinal elastic modulus is more than 8000 MPa, the longitudinal elastic modulus is more than, 3000 MPa, and the surface impact strength is greater than 80 kJ / m ²，
Raw materials come from a wide range of sources. The production of plywood, particleboard, fiberboard and other various shapes of wood, such as log branch, branch, veneer, lath, small-diameter wood, thinning wood, small trees with fire-proof isolation belt and various shrubs, hollow, dry core, large and medium-sized logs can be used to produce reconstituted wood (bamboo) bundles and flocs.
Fast growing biomass materials include fast-growing poplar, willow, Paulownia, eucalyptus, all kinds of fast-growing shrubs and Phyllostachys pubescens. Due to the disadvantages of natural fast-growing biomass materials, such as large difference in structure, low density, low strength and easy deformation, the effective utilization of fast-growing plants is hindered. Because of the reconstitution of plant fiber, its structure is compact, the product performance is greatly improved compared with natural wood (bamboo), and the small-diameter wood and fast-growing wood can be changed into structural timber with certain size and specification. It has the following advantages:
1. A wide range of raw materials, high utilization rate of materials.
2. The products have good mechanical processing and surface decoration properties, and can obtain large cross-section square materials with high strength and homogeneity.
3. The material density can be controlled within 800-1200kg / m by process ³， Applicable to different requirements.
4. The product has a wide range of uses. It can be used to make antique furniture, floor, wooden building, dock, carriage bottom plate, etc., and is widely used in various kinds of decoration.
The project has a broad market prospect, and the implementation of the project is of great significance to improve the technical level of the research and development and industrial application of biomass materials in China
