摘要

分别用氢氧化钾和亚氯酸钠处理木材原料，以移去木材原料中的一部分半纤维素和木素。用这些特制浆料压制的无胶纤维板，无论是板的强度性能还是板的耐水性能都比未处理木材原料制造的无胶纤维板的性能有明显的下降。这一结果表明，木材原料中的半纤维素和木素都对纤维间自生胶粘因素的形成具有重要的影响

Abstract

With wood raw materials treated respectively with NaOH and NaClo 2, parts of hemicellulose and lignin in wood removed. Compared to the binderless fiberboard made of untreated wood materials, both strength properties and water resistance of the boards made of the treated wood materials showed a significant decrease. The results indicated that both hemicellulose and lignin in wood have an important effect on the formation of self bonding of wood fibers.
