China's first "formaldehyde free addition" plywood automatic line scheme released: the number of workers can be reduced by 80%

18/11/2021

China's plywood production capacity is huge, but the production end is scattered. There are more than 5000 small workshops to medium and large-scale production enterprises in China. The enterprise with the largest number of workers has 1000 people, which is a labor-intensive industry. Moreover, the production process of plywood makes manual operation inevitable, but the quality of plywood produced by hand is unstable and can not meet the automation requirements of modern furniture industry. "

On June 4, Liu Xuehong, general manager of composite wood products of polyurethane division of Huntsman company, put forward the current production problems of plywood in China's man-made panels at the conference of automatic line scheme of polyurethane "aldehyde free addition" plywood continuous press, and released the scheme of China's first automatic line of polyurethane "aldehyde free addition" plywood continuous press.

Huntsman company (hereinafter referred to as "Huntsman") was founded in 1970 and provides chemicals, plastics, textiles, footwear, paints and coatings, building materials, etc. Headquartered in Salt Lake City, Utah, the company has more than 10000 employees worldwide, with an operating revenue of about $9 billion in 2018. Compared with the existing manual urea formaldehyde glue process, the automatic production line scheme released this time increases the product value by 25%, reduces the number of workers by 80%, and shortens the return period of the project by 20 months. The production line is expected to be put into operation in the next 12 to 15 months.

Wood based panels mainly include plywood, particleboard and fiberboard. China is the largest producer of plywood in the world. Since the 1950s, China has started plywood production by using the wood of state-owned forest areas in Northeast China as raw materials. Now, 60 or 70 years later, China's plywood industry has developed rapidly.

As one of the commonly used materials for furniture, the national output of plywood reached 179 million cubic meters in 2018, accounting for about 60% of China's wood-based panel output. Last year, China exported 11.3381 million cubic meters of plywood, accounting for 81.89% of China's total export of wood-based panels. Plywood ranks first in China's export of wood-based panels.

"We should also clearly see that there are still a series of problems in the development of China's Plywood Industry: the characteristics of labor-intensive industries are prominent; production automation and continuity need to be improved; the phenomenon of 'scattered pollution' is still prominent in some regional industries," said Shi Feng, Secretary General of China forest products industry association.

On the other hand, Liu Xuehong mentioned that consumers have an increasing demand for formaldehyde free wood-based panels. The wood-based panel uses formaldehyde free adhesive or no adhesive, and other additives containing formaldehyde are not added in the production process. The formaldehyde emission limit is 0.03 mg per cubic meter.

In China, "the output of aldehyde free particleboard accounts for 6% of all particleboards, the output of aldehyde free fiberboard accounts for 2% of all fiberboards, and the output of aldehyde free plywood accounts for nearly zero in the field of plywood." about one third of the downstream applications of plywood are used in indoor scenes, including furniture and decoration materials. Liu Xuehong believes that the wood-based panel industry really needs formaldehyde free, intelligent and automatic upgrading.

To this end, Huntsman and many local and international forces, including the forest products industry planning and Design Institute of the State Forestry and grassland administration, jointly developed the automatic production line of polyurethane "aldehyde free addition" plywood continuous press, and positioned the products of the production line as geothermal plywood, because the formaldehyde in the floor is accelerated under heating, "Only aldehyde free polyurethane glue can ensure that the floor is healthy when heated." Liu Xuehong introduced that compared with the existing manual urea formaldehyde glue process, the product value of the production line is increased by 25%, the number of workers is reduced by 80%, and the return period of the project is shortened by 20 months. Compared with the imported automatic line process of urea formaldehyde glue, polyurethane "aldehyde free addition" The product value of plywood production line is increased by 25%, the total investment in core equipment is reduced by about 30%, and the return period of the project is shortened by 19 months.

Huntsman said that the "formaldehyde free addition" plywood produced by the automatic production line can pass the most stringent American NaF environmental protection certification standard in the world. This certification standard requires that no adhesive, concealer, putty and other substances containing formaldehyde are added to any link in the production process.

"Huntsman has accumulated some practical experience in the production and application of polyurethane adhesive plywood; the forest products industry planning and Design Institute of the State Forestry and grass administration has rich experience and talent reserve in wood-based panel engineering consulting, design and R & D." Shi Feng believes that the two sides give full play to their respective advantages and jointly develop automatic production lines, which can promote the equipment and technology upgrading of China's plywood industry, improve the production scale of the production line and provide high-quality green aldehyde free plywood products for the market.

"We have developed process 1.0 production line for the Chinese market, mainly to make Chinese plywood enterprises affordable and the first step to realize automation. However, it still has room for upgrading. We can achieve 2.0 and 3.0 to promote the development of the industry," Liu Xuehong said
