| 1 | In this paper, phytic acid preparation technics has been studied with paddy bran as raw material. The focus is the hydrolysis condition. | |
| 2 | The preparation method of oxalic acid from oxidation hydrolysis of rice chaff is presented and optimum condition is determined. | |
| 3 | The results showed the common surface treatment methods of rice chaff by coupling agents had little effect on the modification of such a composite; | |
| 4 | China made million tons wood a year, other natural fibers such as rice chaff up to 10 million tons. | |
| 5 | The Effects of the surface treatment method of rice chaff, the content of rice chaff, and the content of recycled HDPE on the mechanical properties of HDPE/rice chaff composite were studied. |
