The non-toxic and non-polluting production of wood-based paper-making adhesives and new production processes with its own intellectual property rights have been successfully developed, and it is announced that China's plywood production will bid farewell to urine mix and phenolic glue.
Since the introduction of phenolic resins, the world's wood-based panel industry has been using urea aldehyde and phenolic resin as important adhesive materials. Although adhesives such as triamine have been available in recent years, it is difficult to produce high-cost equipment and technical requirements. Promote use. However, powdered phenols, benzene and aldehydes are poisonous and harmful substances, and special aldehydes kill human hepatocytes. Therefore, a low-cost, mature process, advanced production methods, and a wide range of raw material sources are needed for the production of artificial wood boards and adhesives. This is the goal pursued by the wood-based panel industry at home and abroad for decades.
Jiang Daoyou has this new technology and has been granted the Chinese Patent Excellence by the State Intellectual Property Office (2000) No. 5 document. The inventor Jiang Daoyou was named as the advanced worker in the packaging industry in Sichuan Province and a nationwide advanced individual in packaging. This new technology has revolutionized the domestic market. The wood-based panel industry has used conventional urea formaldehyde, phenol formaldehyde, and melamine as the wood-based panel adhesive for 100 years. The new adhesive material is not only non-toxic and non-polluting, but also can reduce the production cost by 60% and improve the product quality by two grades. It completely solves the problem of unavoidable dryness, water ingress, high cost, heavy weight and products of phenolic glue. Difficult to drill and other disadvantages. The technology and adhesives can be fully applied to the technical transformation of medium density fiberboard, bamboo wood-based panels, flooring, furniture and decorative board production lines, and small paper mills turning to technical transformation production.
The new technology can also be used for the comprehensive utilization of bamboo materials in the production of bamboo wood-based panels, so that the value of the original bamboo production is 3,000 yuan more than that of the production paper.
