Published: March 2020

Lignin which is hydrophobic due to presence of carbonyl; carboxyl; hydroxyl and phenol functional group, can be used as compatibilizing agent through grafting a hydrophobic part such as polyurethanes. Lignin-based biopolyurethane (bioPU), was synthesized by two stages of reaction viz., polyurethane preparation through reacting 4,4′-Methylenebis (CyclohexylIsocyanate) (HMDI) and polyethylene glycol (PEG, molar mass of 4000 g/mol); bio-PU preparation through grafting lignin onto the polyurethane. The ratio of diisocyanate to polyol and lignin addition were varied in 1: 4, 1:1 and 0.25 g, 0.5 g, 1 g, respectively. Products were investigated by observing FESEM (Field Emmision Scanning Electron Microscope), 1H NMR (Nuclear Magnetic Resonance) and FTIR (Fourier Transform Infra-Red Spectroscopy). The FESEM result shows that lignin based bioPU with isocyanate/polyol ratio 1:4 and 1 g lignin addition is more homogenous than isocyanate/polyol ratio 1:1 and 0.25 g lignin. The NMR and the FTIR spectra reveal the lignin grafed onto polyurethane product. The addition of 0.25 and 1 g lignin resulted in 0.2 and 0.6 hidrophilic/hidrophobic segment ratio, respectively. Furthermore, characterizations of the products confirmed that the lignin-based bioPU can be a promising compatibilizer.

Cu2ZnSnS4(CZTS) has attracted a lot of attention recently as a promising absorber layer material in a heterojunction solar cell. In this work, the Zn1-xMgxO material is substituted for CdS due to its abundant and nontoxic consisting elements. We have studied the band gaps of Zn1-xMgxO alloys with different values of x and the band offsets at Zn0.75Mg0.25O/CZTS heterointerface based on the first-principles and pseudopotential calculation method. The band gaps enhance linearly with the increasing values of x. The total density of state and local density of state of each atom in Zn0.75Mg0.25O/CZTS supercell are calculated. We predict that the heterojunction of Zn0.75Mg0.25O/CZTS is a type II heterointerface with a 0.2eV of conduction band offset, during which the conduction band minimum of Zn0.75Mg0.25O is lower than that of CZTS.

Published: March 2020

Water lubricated bearings are commonly used equipment in ship and other fields. The friction factors and other parameters of bearing materials have great influence on the performance of Water lubricated bearings. In this paper, a comprehensive bearing test platform was established, the slurry wear test of bearing material was carried out on the MPH corrosion wear tester, and the effects of wear time, sliding speed and load on the friction performance of bearing material were obtained. And then the effects of different additives on the optimization and improvement of the wear resistance and friction coefficient of bearing bushes have been systematically analyzed. The results show that the friction coefficient increases when glass fiber is added into PTFE matrix, but the effect of carbon fiber is not significant. The material composed of PTFE matrix and graphite not only improves the wear resistance, but also reduces the friction coefficient. Rigid additives increase the hardness of PTFE matrix, while soft additives decrease the hardness of PTFE matrix. Almost all kinds of additives can reduce the impact strength of PTFE matrix.

Study on the Influence of Distributed Conductive Capacitance on CVT Error haracteristics on Test Wire
Authors: Li Jinjin , Mo Fanghua
Published: March 2020

The CVT reduces the primary voltage proportionally by the voltage dividing capacitor. When there is a distributed capacitance, the voltage division ratio changes, which affects the accuracy. When performing CVT field error test, it is necessary to attach a test wire to the CVT. When the distance between the connected test wire and the CVT casing is insufficient, the distributed capacitance will be introduced. The distributed capacitance is superimposed on the CVT’s own capacitance, resulting in the CVT unnormal partial pressure ratio. This paper quantitatively analyzes the distributed capacitance introduced by the test wire with the change of the mounting angle to the tested CVT, and obtains its quantitative influence on the error data. According to the degree of influence, the recommended angle of the test wire is given according to the degree of influence. The on-site error test ensures that the test data is accurate and has great significance.significance
