Effects of Rosin Sizing Agent on the Fixation of Boron in Styrax
The aim of this study was to evaluate the effect of rosin upon fixing boron in Styrax tonkinensis (Piere) wood treated with mixtures of 3% boric acid and 1% rosin sizing agent. After treatment, wood samples were also analyzed by scanning electron microscope observation and energy-dispersive X-ray spectroscopy (SEM-EDX). The results showed that all boron-rosin formulations impregnated Styrax ton...
متن کاملeffect of alum consumption levels in alum-rosin sizing on multilayered paperboard properties
sizing of paperboard has a distinctive position in packaging grade paperboard material. optimization of sizing by alum-rosin at neutral ph in 4 layered paperboard (330 g/m2) wereevaluated in this study to find the optimum ratio of alum- rosin loading in the process. fixed amount of 1% cationic dispersed rosin together with alum as a fixing agent at 5 different levels of 1, 1.5, 2, 3, and 4% (ba...
متن کاملSurface Sizing Application of Waterborne Epoxy Resin on Low Basis Weight Paper
Reducing basis weight could lead to huge savings of forest resources as well as energy consumption and waste treatment in the papermaking process. However, low basis weight paper generally lacks normal strength and stiffness. The lower the basis weight of the paper, the more important is surface sizing. Highly cross-linked cured epoxy resin, due to its epoxy group and phenyl group, has gained s...
متن کاملSynthesis, Characterization, and Bioactivity of Rosin Quaternary Ammonium Salt Derivatives
Two series of rosin quaternary ammonium salts (QAS) were synthesized using the same path. The structure of the target products was characterized by HPLC, MS, IR, and 1 HNMR, and the bioactivity was determined by filter paper method using Trametes versicolor (white-rot fungus) and Gloeophyllum trabeum (brown-rot fungus), which are two kinds of general wood decay fungi in nature. The results show...
متن کاملAn Ultrasonic Technique for Sizing Surface Cracks
Rayleigh surface waves are proposed as a non-destructive method to find the depth of surface cracks. The paper describes how dynamic photoelasticity was used to develop an understanding of the subsurface interactions between R-waves and a narrow slot. A frequency analysis of the transmitted wave confirmed that the slot acts as a low pass filter for the high frequency Fourier components of the i...
