Abstract

Sposób wytwarzania płyt pilśniowych w technologii suchego formowania, w której zrębki z materiału drzewnego poddaje się rozwłóknianiu, masę włókien zakleja się, z wysuszonej masy formuje się kobierzec, który następnie poddaje się prasowaniu, a wyprodukowane płyty schłodzeniu i, ewentualnie, szlifowaniu, charakteryzuje się tym, że na powierzchnię kobierca włóknistego, przed etapem prasowania, nanosi się mieszaninę gruntującą składającą się z pyłu drzewnego i skrobi w stosunku wagowym 1 : 2 ÷ 2,5, w przeliczeniu na skrobię ziarnistą, oraz wody w takiej ilości, aby lepkość mieszaniny gruntującej wynosiła 200 - 400 mPa•s, przy czym mieszaninę gruntującą nanosi się w ilości 20 - 40g/m2.The method of producing fiberboard in dry forming technology, in which woodchips are subjected to fiberisation, the mass of fibers is glued, the dried bed is formed into a bedcloth, which is then subjected to pressing, and the produced boards are cooled and, optionally, grinded, characterized by that a primer mixture consisting of wood dust and starch is applied to the surface of the fiber carpet before the pressing stage in a weight ratio of 1: 2 ÷ 2.5, based on granular starch, and water in such an amount that the viscosity of the primer mixture is 200 - 400 mPa • s, the priming mixture is applied in an amount of 20 - 40g / m2.
