Abstract

With the wide-angle X-ray densitometer, the infrared spectrometry instrument, the Sigma 700 high-powered surface tension and tangency angle instrument and the thermo gravimetric analyzer, the research compared the different properties between the untreated rice strawand the rice strawtreated atthe temperaturesof 110 degrees centigrade and 160 degrees centigrade, including crystallinity, chemistry composing, soakage and pyrogenation character, to find outthe referential foundations forthe selection of drying temperature forthe production of artificial board. The result showed that after treated at the temperature of 160 degrees centigrade, straw had decreased crystallinity and changed lignin content, which caused the reduced mechanics intension, the change of chemistry composition andworseningof soakage.Therefore,160 degrees centigradewas notthe ideal drying temperature of the rawmaterials. The temperature of 110 degrees centigrade didn't affect the properties of the rice straw and therefore could be used as the drying temperature of rawmaterials.[Ch, 3 fig. 3 tab. 13 ref.]
