    摘要:

    以玉米秸稈為研究對象，采用自制秸稈固化成型設(shè)備生產(chǎn)成型塊，分別考察成型壓力、加熱溫度及物料含水率對成型塊物理品質(zhì)和力學(xué)性能的影響，引入軸向位移、徑向峰值位移、峰值壓力和名義應(yīng)力等概念衡量成型塊的力學(xué)性能。研究表明：成型壓力、溫度及物料含水率對成型塊的松弛密度、抗變形性和抗?jié)B水性影響顯著，當(dāng)壓力在60～90MPa，加熱溫度在75～100℃，物料含水率在8%～12%時，可以生產(chǎn)出性能優(yōu)良且便于儲運的成型塊。

    Abstract:

    Corn stover was taken as the object in the research. The material and compression character, the effects of heating temperature, moisture content and pressure on the physical quality and mechanical properties of corn stover were studied respectively. During the study, axial displacement, diametrical peak displacement and peak stress were all used to scale mechanics properties of corn stover. The results showed that when compression pressure of 60～90MPa applied, moisture content of the grind was 8%～12% and heating temperature was at 75～100℃, the produced briquettes was with high-quality which was easy to store and transport.
