发布时间：2021-02-08 - 摘要：The manufacturing technology and properties of the composite board made from wood fiber and wheat straw particle were investigated. The results showed that it was possible to make the composite board by sandwiching wheat straw particle between 2 layer wood fiber. The properties of the board were able to meet the requirement of National Standard for medium density fiberboard completely.关键词：wood fiber;Wheat straw particle;Fiber/particle composite board;Technology

发布时间：2021-02-08 - 摘要：According to characteristics of wheat straw board, the making of fire retardant wheat straw boards with four types of fire retardants were investigated by using the orthogonal experiment method. The fire retardant properties of the boards were evaluated by the oxygen index and smoking density. Meanwhile, properties of the boards were tested and analysed. Results showed that the fire retardant properties of the boards have been improved obviously through fire retardants treatment, but some physical and mechanical properties of board decreased. In addition, the optimum technical parameters on making fire retardant wheat straw board were presented.关键词：Wheat straw board;Fire retardant

发布时间：2021-02-08 - 摘要：Surface roughness of Moso Bamboo （Phylltachys pubescens） was measured by a fine stylus method and analysed with three surface roughness parameters, which were maximum individual peak to valley height（ R y）,average roughness（ R z） and mean peak to valley（ R a）. Results showed that the outer surface of bamboo was smoother than the inner part and the surface roughness was closely related to both bamboo age and sanding. Compared with the surface of Munchurian Ash （Fraxinus munchurica） and Beech （Fagus spp.） wood, the surface of outer bamboo was relatively smoother.关键词：Stylus method;surface roughness;Outer of bamboo;Inner of bamboo

发布时间：2021-02-08 - 摘要：The reaction of cotton fiber and other polysaccharides with formaldehyde vapor under the catalysis of inorganic salts was studied It was found that the catalysts kind, concentration and reaction time played an important role in the vapor phase formylation The results indicated that ZnCl 2 was the most efficient catalysis among the salts ZnCl 2, Zr（SO 4） 2 and Al 2（SO 4） 3 There existed an optimum concentration when ZnCl 2 was employed, i e , the highest weight percent gain （ WPG ） was obtained at a catalyst content of 8 2×10 5 Meanwhile, extending the reaction duration was helpful to increase WPG Fourier transform infrared spectrometry （FT IR） and high performance liquid chromatography （HPLC） analyses illustrated that cross linking reaction happened between formaldehyde and fiber WPG was less when compared cotton fiber with other cellulose model compounds, which suggested the cross linking was related with steric effect and finite zone HPLC spectrum of cellobiose proved digestible polysaccharide formation关键词：catalyst;formaldehyde;Cellulose;Cross linking reaction
