Abstract


In this paper, straw fibreboard as raw materials is modified by micro-nano fibril / melamine, the adoption of different methods of straw of different density fiberboard impregnated to deal with the main analysis of the modified surface properties of straw fiberboard. Analysis of various factors on the dimensional stability of fiberboard straw and the effects of MOR MOE. Winner 2005 through the use of laser particle size analyzer for particle size to micro-nano fibril analysis; using FEI Quanta 200 environmental scanning electron microscopy analysis of the use of micro-nano fiber Winner 2005 laser particle size analyzer to carry out micro-nano fibril diameter analysis; using FEI Quanta 200 environmental scanning electron microscopy analysis of morphological changes in micro-nano fibril; the use of DX-2000 X-ray diffraction carried out on micro-nano fibril crystallinity change analysis; the use of DX-2000 X-ray diffraction of the micro - satisfied fibril analysis to changes in crystallinity.Through the micro-particle analysis can be known, after AH 100D high-pressure homogenization is the instrument to deal with 800bar pressure, as the reduction of particle size, particle surface area increases rapidly after the particles are homogeneous to the existence of micro-, nano - very few, this is because the particles under external force in the mechanical separation into nano-level, but once the external forces are removed, particles will be reunited into a micron-size particles, it is more difficult to obtain nano-particles. Micro / satisfied fibril solution tablets The micron-size particles to the existence of many. 1.0 g / L Micro / satisfied after a homogeneous solution after fibril diameter less than 5.142% total 1μm, 5μm accounted for less than 56.435%, 67.174% accounted for less than 10μm, less than 10% of the particle size of not more than 0.165um. 50% less than the 3.146um. 90% less than the 18.119um, the average particle size 8.870um. Most of the treated fibers in the lateral size of 300nm and 1μm range, they have great length, about 60-120.By the orthogonal test, we can see that straw man-made board to a different density, different soaking time, different concentrations of micro-nano fibril orthogonal experiment, after measuring the performance of test material through a comprehensive analysis of the data, the best Modification of process parameters, analysis of test results of various factors on the impact of micro-nano fibril get / MF modified straw fiberboard best dimensional stability of the process parameters
