In this study, the possibility of using adhesives of natural origin for the manufacture of wood fiber-based lightweight panels was investigated. The boards, of a density ranging from 150 to 250 kg/m, were glued together using commercial urea-formaldehyde resin (control board), solutions of rye flour and potato starch and two types of starch: oxidized and gelatinized. The density and density profile, compressive strength, modulus of elasticity, acoustic properties and thermal conductivity were determined in the produced boards. These studies show that when food components are used as binding agents in the manufacture of lightweight wood fiberboards, the properties obtained can be comparable with those of commercial boards manufactured using synthetic agents.
在本研究中，对使用天然来源的粘合剂制造木纤维基轻质板的可能性进行了研究。密度范围为150至250 kg/m的板材，使用商用脲醛树脂（对照板）、黑麦粉和马铃薯淀粉溶液以及两种类型的淀粉：氧化淀粉和糊化淀粉进行胶合。测定了所生产板材的密度和密度分布、抗压强度、弹性模量、声学性能和热导率。这些研究表明，当在制造轻质木纤维板时使用食品成分作为粘合剂时，所获得的性能可与使用合成剂制造的商用板材相媲美。
