摘　　要：众所周知摩尔比和UF树脂中游离甲醛有密切关系。在摩尔比不变,尿素分次加入量的比例也不变的条件下能否降低UF树脂中游离甲醛,刨花板甲醛释放量和热压工艺有无关系,这些都是本文要探索的内容。As we know, the mole-ratio is closely related to free formaldehyde in UF resin. The main explored subjects in this paper are concerned as follows; (1) the possibility of reducing the free formaldehyde in UF resin under the condition of constant mole-ratio and constant ratio of portion-wise addition of urea. (2) The relation between the amount of formaldehyde-release from particle board and the hot-pressing technique.
