【摘要】 通过模压发泡工艺制备一次性淀粉餐具,研究了工业化生产过程中模压发泡工艺的参数及一次性淀粉餐具的性能。结果表明,模压发泡最佳工艺条件为上模温度190～200℃,下模温度为180～190℃,保压时间为25s。该工艺条件制备的一次性餐具其力学性能、卫生指标和生物降解性能达到国家标准要求。更多还原

【Abstract】 As for the disposable tableware made of biodegradable-starch by means of foamed molding technology, the authors studied the technological parameters of industrialized production and the characteristics of such tableware. The test results showed that the optimum technological conditions should be: temperature of upper mould 190～200℃, temperature of lower mould 180～190℃,time for pressure retaining 25 sec. The disposable tableware made by this technology could meet the requirements stipulated by the state standard in mechanical properties, hygienic indexes and bio-degratability.更多还原
