[China Packaging Network News] On January 9, the "modified molded" biomass new material developed by Professor Zhou Xiaofan of Nanjing Forestry University can replace the wood-plastic materials in the traditional wood-based panel technology, and can effectively improve the bending of the wood-based panel. Strength and other basic properties, to avoid the use of adhesives and other environmental pollution chemicals, can also be applied to personalized furniture and other fields. At present, traditional wood-based panel manufacturing processes require adhesives, and wood plastics often used in wood-based panels such as plywood, particle board, and fiberboard are prone to “deformation†in the pyrolysis process, and do not guarantee bending and tensile strength, and poor water absorption performance. In addition, it is harmful to environmental pollution and human health. If it is abandoned, volatile chemicals such as benzene and formaldehyde are easily released into the atmosphere, producing ozone, affecting the growth of organisms and human health, and even causing carcinogenicity. When he enters Zhou Xiaofan’s office, he sees three models of new material “models†on his office. First, a small bag of plastic particles, like the grain shape, comes into view. It is understood that this is before the “upgradeâ€. Basic materials. According to Zhou Xiaofan, the traditional corn stalk is a natural polymer material, but due to its low thermal decomposition temperature, it begins to decompose at 280°C, and there is no way to use thermoplastics for reprocessing. The new type of biomass plastic particles only need to maintain the temperature between 120-150 degrees to prepare a new type of biomass straw products. It is understood that after Professor Zhou Xiaofan’s use of abandoned cotton stalks and wood processing residues such as mixed board, sawdust, and wood flour, he uses a special preparation process to plasticize the crop straws, which can be developed in 10 minutes. New type of "modified" biomass materials, with "self-plasticizing", "no glue", strong bending performance, high water absorption, anti-mildew, formaldehyde-free and other eco-friendly performance, preparation of formaldehyde-free adhesive Agent high density artificial board. There was also a pile of "upgraded" wood with strong hardness, high water resistance, similar flooring, and a thin plastic film in the shape of a blade. According to reports, this is the two “new bodies†that are shaped by new materials. The former can be used as a substitute for traditional wood-plastic materials, applied to floors and mahogany furniture, and the density is increased from 1.0g/cm3 to international standards for mahogany furniture. 1.3-1.5g/cm3, bending strength up to 70MPa, three times that of ordinary wood-plastic materials international standards, and strong water absorption, increased more than 20 times, anti-corrosion, cost reduction from the original 9300 + yuan per ton to one ton 1825 yuan, the original price of 1/5. The latter can be used for the preparation of high-strength straw plasticized paper, such as high-strength, waterproof and moisture-resistant “corrugated paperâ€, capacitor paper and automotive filter paper. Not only that, due to the characteristics of antibacterial and hygroscopic properties of underwear made of bamboo fiber, the demand for bamboo fiber textiles is increasing day by day, but due to the traditional properties of original bamboo fiber, its properties are easily destroyed and the cost is high. . Prof. Zhou introduced that the biomass “modified plastic†new material can also be applied to the bamboo fiber field. The production process is simple, and its antibacterial properties and elasticity are improved. It is eco-friendly and cheap.
