Artificial boxwood is a board or molded product made of wood or other non-wood plants, which is separated into various unit materials by certain mechanical processing, with or without the application of adhesive and other additives. It mainly includes three types of products, such as plywood, shavings (slack) and fiberboard. There are hundreds of extension products and deep processing products. The birth of artificial boxwood, marking the beginning of the modernization of wood processing. In addition, the artificial boxwood can also improve the comprehensive utilization of wood, and 1 cubic meter of artificial boxwood can replace 3 to 5 cubic meters of logs.
At the beginning of the first century BC, the Romans were familiar with the principle of veneer manufacturing and plywood manufacturing.
In 1812 the French invented the veneer sawing machine.
In 1834, France issued a patent for the planer.
After 1844, the improved rotary cutting machine was officially used in industrial production. Since then, the rotary cutting machine has been continuously improved, which has promoted the development of the plywood industry. In the middle of the 19th century, Germany first established a plywood factory.
In 1887, Germany used sawdust and blood glue to make plates, which was the beginning of particleboard.
In 1889, Germany obtained the first patent for the use of wood shavings to make particleboard. The emergence of synthetic resin adhesives in the early 20th century prepared conditions for the industrial production of particleboard.
In 1898, the United Kingdom first made semi-hard fiberboard on a rotary paper machine.
In 1914, the United States produced insulating sheets from groundwood pulp and built insulated fiberboard factories.
In 1916, the dry forming process first appeared in Austria.
In 1924, the United States created the Massonna de-blasting (blasting) fiber separation technology. In 1928, it was able to produce high-quality hard fiberboard.
In 1931, Sweden invented the Aspend Law, and in the following year established the first hard fiberboard factory produced in this way in Sweden. So far, the fiberboard manufacturing industry has become an independent industrial category from the paper industry.
In 1935, France used waste veneer to make long shavings. In the paving process, the layers of shavings were vertically intersected to form a slab. It is the leader of the orientation technology in particleboard. In 1937, Switzerland proposed the manufacturing process of three-layer shaving structure.
The first fully equipped particleboard factory was established in Germany in 1941, which enabled the particleboard industry to complete its technical preparation phase.
In 1943, the United States succeeded in the production of dry and semi-dry manufacturing processes. In the early 1950s, factories were established in the United States, the Federal Republic of Germany, Czechoslovakia, and Austria to produce hardboard using the above two methods.
In the late 1940s, with the British and German research on the continuous production of the particle board for the Badreif method and the Ocal method, and the corresponding complete sets of continuous production equipment, the production of particleboard into the industrial system.
In the early 1960s, medium-density fiberboard was made based on the dry process. In 1966, the first medium-density fiberboard plant was built in the United States.
