玉米秸秆纤维制备及耐热规律研究

Research on the Preparation of Corn Stover Fiber for Road Use and Heat Resistance Law

纤维作为一种优良的改性材料,被广泛应用于沥青材料改良中。为了探究用玉米秸秆制备路用纤维材料的可能性,对玉米秸秆进行去芯取皮,调整玉米秸秆茎皮浸泡时间,破碎仓给入量和破碎时间以制备出符合路用纤维要求的玉米秸秆纤维,其次对玉米秸秆纤维进行不同温度热处理,并用RGB色卡对玉米秸秆纤维颜色变化进行表征,探究玉米秸秆纤维的适用施工拌和温度。

As an excellent improvement material,fiber is increasingly used in the improvement of asphalt materials.In order to explore the possibility of using corn straw to prepare corn straw fiber materials,the corn straw was cored and peeled,the soaking time of corn straw stalk was adjusted,the amount of crushing bin feed and the crushing time were adjusted to prepare corn straw fiber that met the requirements of road fiber,and then the corn straw fiber was heat treated at different temperatures,and the color change of corn straw fiber was characterized by RGB color card,and the applicable construction mixing temperature of corn straw fiber was explored.
