摘要

为了更快捷地对造纸原料热水抽提物进行检测，本研究用微波加热方法代替水浴加热。考察了功率和时间两个因素对造纸原料热水抽提率的影响。结果表明，对2 g稻草粉末做热水抽提物检测时，采用微波辐射5 min，辐射功率用400～600 W，可获得与传统恒温水浴180 min反应相同的检测效果。经重复实验，微波法大幅提高了检测效率，并且具有一定的可重复性。

Abstract

In order to improve detection of hot water extraction from paper raw material, microwave heating is used in paper raw material test instead of the water-bath heating. Two main factors for efficiency of hot water exaction: irradiation power and time are carefully studied. Experiment results show that when hot water exaction from 2 g straw powder is tested, microwave heating with 400~600 W irradiation power and 4~6-minute irradiation time can achieve the same efficiency as water-bath heating with 180-minute time. Many experiments confirm that microwave heating improves the efficiency of detecting tests greatly and the method is also reproducible.
