Abstract: The present study investigated the anatomical features and fibre morphology of Hedysarum scoparium by using light microscopy (LM), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). The results showed that the cells are divided into four types: vessel, fibre, ray parenchyma and axial parenchyma. Hedysarum scoparium belongs to diffuse-porous wood. Rays are exclusively uniserial. Arrangement of intervessel pits is alternate type. Although the mean fibre length of Hedysarum scoparium is 0.68mm, this shrub has quite good fibre morphology compared with China white poplar, wheat straw and red pine. TEM images showed that cell wall of the fibre is typically divided into three layers including the primary wall (P), the middle lamellar (ML) and the secondary wall (S1, S2 and S3).

Abstract: Milled wood lignin (MWL) from Jacaranda copaia was prepared. In order to study the change of the structure, MWL was cooked by kraft method in existence of xylan. The combination of infrared spectra analysis and 13C-NMR was used to identify the LCC formed during kraft cooking. The research indicated that the lignin linkages were easy to be cleaved by kraft cooking, especially α-aryl ether linkage and β-aryl ether linkage. There were new LCC structures formed during the cleaving of lignin linkages. Some new LCC which was connected with benzyl ether linkage was formed from β-O-4 lignin and 5-5 lignin structures and xylan. The newly formed LCC was stable in alkali solution.

摘  要:研究了HNO3/NaNO3预处理、KMnO4预处理和H2O2强化对桉木RDH硫酸盐浆氧脱木素的改善效果,并与常规KP浆进行了对比。结果表明,少量H2O2对RDH浆氧脱木素具有良好的强化效果,较佳的H2O2用量为0.8%。在制备低卡伯值纸浆时,采用RDH蒸煮与H2O2强化的氧脱木素相结合的制浆方法比采用常规KP蒸煮与H2O2强化的氧脱木素相结合的方法更有利于保护纸浆的黏度。在氧脱木素前对RDH浆进行HNO3/NaNO3或KMnO4预处理也有利于改善氧脱木素的效果,提高残余木素的脱除程度,其中KMnO4预处理还可以较明显地提高纸浆白度。但相对而言,这两种预处理方式更适合于用来改善常规KP浆这类残余木素含量较高纸浆的氧脱木素。

Abstract: Improved oxygen delignification of RDH (Rapid displacement heating) kraft pulp from eucalyptus by pretreatment with HNO3/NaNO3 and KMnO4, and reinforcement with H2O2 was studied in the paper. The results showed that addition of a low charge H2O2 to oxygen stage enhanced oxygen delignification of RDH pulp, and the optimum charge of H2O2 was 0.8%(on oven dry pulp weight). The pulping method, which combined RDH cooking with H2O2-reinforced oxygen delignification was superior to that which combined conventional kraft cooking with H2O2-reinforced oxygen delignification in the production of pulp with low kappa number and high viscosity. Pretreatment with HNO3/NaNO3 and KMnO4 prior to oxygen stage could improve efficiency of oxygen delignification, increase residual lignin removal rate, KMnO4 pretreatment also increased effectively brightness of the oxygen-delignified pulp. Relatively, oxygen delignification with HNO3/NaNO3 and KMnO4 pretreatment was more suitable for conventional kraft pulp than RDH pulp.

Abstract:Dioxane lignin was extracted from control sample and laccase-mediator system (LMS) deinked pulp of old newspaper. Their structures were analyzed by elemental analysis, functional groups determination, FTIR. Comparing with the lignin from the control pulp, phenolic hydroxy and methoxyl content of the lignin from LMS deinked pulp decreased, while content of carboxyl and carbonyl groups increased. FTIR results showed that part of lignin was degraded and dissolved during the LMS treatment. Gel permeation chromatogram was used to investigate the change of lignin molar mass. Number average molecular weight, weight average molecular weight and polydispersity of lignin from LMS deinked pulp were lower than those of lignin from the control pulp, which indicated that lignin was somewhat degraded during the LMS deinking.

Abstract: The release mechanism of dissolved and colloidal substances (DCS) during repulping of mixed office wastepaper (MOW) was investigated using gas chromatography (GC). Results showed that glucose was the predominant sugar unit of the carbohydrate portion. Sodium hydroxide and hydrogen peroxide led to an increase of the concentration of sugar units, while the deinking agent did not. The released resin and fatty acids (RFAs) were mainly composed of dehydroabietic acid, hexa-decanoic acid, bis-(ethylhexyl)phthalate, etc. The deinking agent had a large effect on the amount and the composition of RFAs. Sodium hydroxide was of help the release of RFAs. The total amount of RFAs decreased a little after adding hydrogen peroxide.

Abstract: The sulfomethylated lignoamine was prepared with masson pine lignosulphate by Mannich reaction and sulfonation reaction. Then the organic-inorganic compound modified lignin-based flocculant could be obtained by further mixing with sodium aluminate solution. The modified lignin-based flocculant was adopted to treat the antibiotics pharmaceutical effluent. The flocculation conditions were optimized. The removal rates of CODCr, SS and colourity of the effluent could reach 61.2%,96.7% and 91.6% respectively under such conditions as effluent pH value 6.0 and flocculant dosage 120 mg/L etc. Moreover, the comparison tests with various flocculants indicated that the flocculation performance of the modified lignin-based flocculant apparently prevailed over such flocculants as polyacrylamide (PAM), polyferric sulfate (PFS), potassium aluminium sulfate (PAS) and ferrous sulfate (FS) etc.

Abstract: This paper introduced spectrophotometry as a new technology to determine the sedimentation stability of coatings. Several factors including the ratio of clay to GCC, the dosage of starch and CMC were studied. The result showed that it was feasible to use the spectrophotometic method to determine the stability of low solid content and low viscosity coatings. With the increase of PVA and CMC dosage, the sedimentation stability of coatings increased. Well dispersed pulp-type pigments had a positive impact on the coating stability, while starch had no obvious effect.

Abstract: Double disc refiners in series adopted different power distribution in the high speed machine refining system was studied. Fiber morphology, dewatering rate, paper property and refining energy were researched after softwood long fibers were refined by the refiners. Compared with the average power distribution, low intensity refining at first, and then following by high intensity refining at the second refiner could increase SEL (specific edge load), improve the refining effect and decrease energy consumption. If power distribution proportion was 55% to 45% or 60% to 40% in first stage and second stage refiners respectively, it could reduce fiber length and dewatering rate both were to the disadvantage of paper machine speed and output. If power distribution proportion was 45% to 55%, the optimum refining effect could be achieved. Dewatering rate and bursting strength could be improved, but tensile strength could not be increased apparently.
