据预应力原理造纸技术发明人张玺钧先生介绍,“预应力原理造纸专利技术”是当今材料物理学、工程力学与环保学等多学科应用的科研成果的技术结晶,其亮点在于使纸张强度与节约用料得到充分兼顾。造纸时把纸浆抄造在预先施加拉应力而处于拉伸状态的经纬线上,依靠纸纤维的氢键结合力把经纬线固定在纸中,撤销拉应力后,经纬线收缩对纸纤维产生压应力,将其能量储存在纸品中。纸的强度由纸中储存的外加能量和经纬线决定,纸浆纤维仅为填充辅助材料。采用预应力原理造纸,能同时起到提高强度、节约材料、减轻定量的作用。
According to the theory of prestress, Zhang Xijun, the inventor of papermaking technology, introduces the technology of prestressing paper technology, which is the technological achievement of the multidisciplinary application of materials physics, engineering mechanics and environmental protection. Its bright spot lies in making the paper strength And material savings have been fully balanced. Pulp papermaking papermaking in pre-applied tensile stress in the tensile state of the latitude and longitude lines, relying on paper fiber hydrogen bond strength of the latitude and longitude lines fixed in the paper, after the withdrawal of tensile stress, latitude and longitude contraction of paper fiber compressive stress , The energy stored in the paper products. The strength of the paper is determined by the energy stored in the paper and by the latitude and longitude lines, and the pulp fiber is only filled with the auxiliary material. The principle of prestressed paper, can also play to improve strength, save material, reduce the quantitative effect.
