In view of the difficulty in thermoplastic processing of bamboo powder and the fact that the same modification method gives quite different modification effects on different types of bamboo powders, this project aims to obtain “simulated bamboo powder” via setting up inverse whole component fitting model on the basis of elucidating of bonding interactions in inner- and inter- bamboo components, then to explore thermoplastic process modification mechanism of bamboo powder by comparing modification effects of different components and “simulated bamboo power”. The project deals with the melt modification of bamboo powder by using reactive twin-screw extruder with function of visualization and real-time processing data acquisition. More specifically, on the basis of solving of the difficulty in melting processing that arises from chemical bonding, hydrogen bonding and Van de Walls force, both intermolecular in bamboo power components and intramolecular with outside molecules, and by fitting of lignin-carbohydrate complex between hemicellulose and lignin, hemicellulose -protein conjugation and chemical bonding of cellulose and hemicellulose, establishment of fitting method of real bamboo system is expected. In addition, the project aims to elucidate the thermoplastic processing modification mechanism and to further predicate the melting process of real bamboo powder. The ultimate goal of the project is the establishment of simulation and predication of thermoplastic processing modification of bamboo powder to offer a new means and solution to bamboo fibre thermoplastic processing and the design and production of bamboo-plastic product, and to lay a scientific foundation for development of bamboo-plastic products.
