木片是造纸、纤维板和刨花板的原料,是枝椏利用的重要途径。自六十年代初提出在我国利用枝椏生产木片以来,至今已有二十多年,但木片生产并未得到应有的重视和发展。据统计,一九八○年全国木片生产能力为1 00万层积立米,实际产量只有24万层积立米左右,仅为每年造纸原木消耗量的2~3%,纤维板和刨花板主要以木材加工剩余物为原料,利用枝椏的数量也比较少。而在一些发达国家中,木片被广泛使用,造纸大部以木片为原料,已成为大宗林产品。相比之下,我国木片生产的发展是缓慢的.
Wood chips are paper, fiberboard and particleboard raw materials, is an important way to use branches. Since the early 1960s, it has been more than 20 years since it was proposed to use woodchips in our country to produce shreds, but the production of wood chips has not gained the due attention and development. According to statistics, in 1980, the nation’s woodchip production capacity was 10,000,000 cubic meters of cubic meters. The actual output was only 240,000 layers of cubic meters, accounting for only 2 to 3% of the annual consumption of paper-made logs. Fibreboard and particleboard were mainly processed by wood processing Residues for the raw material, the use of the number of branches is also relatively small. In some developed countries, wood chips are widely used, most of the paper made of wood as raw material, has become a bulk forest products. In contrast, the development of wood chip production in China is slow.
