摘　　要：研究3种不同地区旧报纸(ONP)的基本特性,如纤维特性及无机成分等。在常规碱法脱墨条件下,对比了3种不同地区ONP脱墨效果的差异。结果表明:浮选脱墨后国产旧报纸(L-ONP)的白度提高了约10%,而欧、美旧报纸(E-ONP和A-ONP)仅提高不到5%,同时L-ONP脱墨浆的ERIC较低,且油墨剥离率(ID)和油墨去除率(IE)均远高于A-ONP和E-ONP,说明国外进口的ONP在常规碱性条件下的脱墨效果较差。The characteristics of three ONPs were studied, such as fiber properties and inorganic content, and the deinking efficiency in alkaline conditions were also compared among three ONPs. The results showed that the brightness of L-ONP increased about 10% compared to the blank, whereas the brightness of E-ONP and A-ONP increased less than 5%. After flotation deinking and hyperwashing process, lower of ERIC, higher ink detachment and ink elimination can be achieved for L-ONP than those for both E-ONP and A-ONP in conventional alkaline deinking conditions.
