稻壳制一次性可降解筷子的性能检测研究

The Properties of Rice Husk for Degradable Disposable Chopsticks

以稻壳粉为主要原料,以羧甲基纤维素钠和黄原胶为辅助原料制作一次性餐筷,并对其耐水性、耐酸性、耐热油性、跌落性和降解性等进行试验检测。结果表明,规格为4 mm×242 mm×8 mm,质量约为20 g/双,静曲强度为25.12 MPa,无破损和变形现象,降解时间为23 d,各项性能达标一次性餐筷使用标准。

In this experiment, rice husk powder as the main raw material, using sodium carboxymethyl cellulose and xanthan gum as auxiliary raw material for the production of disposable chopsticks and the water resistance, acid resistance, oil resistance, drop and degradation of test. The results show that： the size of 4 mm×242 mm×8mm, weighs 20 grams/pair, static bending strength is 25.12 MPa, no damage and deformation, degradation for 23 days, each performance standard of disposable chopsticks using standard.
