°</sup> 的等距直齒磨盤，研究了闊葉木漿恒間隙 (0.1mm ）循環(huán)磨漿特性。結(jié)果表明，漿料打漿度升高導(dǎo)致其黏度及磨區(qū)剪切應(yīng)變降低，使得恒間隙循環(huán)磨漿總功率降低，且功率降低的速率隨打漿度的升高而逐漸增大；而打漿度及纖維平均長度的相對(duì)變化曲線可以用于表征磨漿過程中磨齒對(duì)纖維的切斷及細(xì)纖維化作用程度。本研究提出了一種基于紙張的微觀形貌定量表征的磨漿優(yōu)化方法，發(fā)現(xiàn)其確定的磨漿極限與紙張強(qiáng)度指標(biāo)變化具有較好的相關(guān)性，以期為低濃磨漿過程的表征、磨片的優(yōu)化設(shè)計(jì)及其高效低能耗運(yùn)行提供參考。-龍?jiān)雌诳W(wǎng)" />
