主要研究了不同转子构型对炭黑分散性及胶料力学性能的影响。实验表明，在相同混炼条件下，6棱同步转子混炼的胶料获得最好的炭黑分散性，4棱转子的次之，在3组2棱同步转子中，2棱功能转子的混炼效果最好。说明通过改变转子构型，可有效地改善混炼胶中炭黑的分散性，提高胶料的力学性能。     

Functionalization of carbon support and its influence on the electrocatalytic behaviour of Pt/C in H2 and CO electrooxidation

Chemical modification of Carbon Vulcan XC-72R for fuel cell applications has been undertaken. Treated carbons were used as carriers for the deposition of Pt nanoparticles and used as electrocatalysts. The influence of the carbon treatment, as well as that of the Pt nanoparticles generation and their deposition route has been studied. The behaviour of the electrocatalysts in the CO and hydrogen oxidation reaction (HOR) has been studied. It was observed that carbon pre-treatment lead to difference behaviour in the CO oxidation reaction compared with the performance over non treated supports. In this way, CO oxidation was controlled by the nature of the support rather than by the nature of the Pt particles alone.

Effect of filler network on dynamic viscoelastic properties of uncured polymethylvinylsiloxanes filled with silica and carbon black

Dynamic properties of polymethylvinylsiloxane (PMVS) filled with filler‐blends composed of carbon black (CB) and silica (SiO₂) were investigated using an advanced rheometric expansion system. A variety of weight fraction of CB to SiO₂ were 0/100, 10/90, 30/70, 50/50, 70/30, 90/10, and 100/0, and a bifunctional organsilane, bis(3‐triethoxysilylpropyl)tetrasurfane, was used to facilitate the filler dispersion. The results reveal that the incorporation of CB/SiO₂ filler‐blends into PMVS result in a reduced Payne effect. This effect reaches a minimum when the ratio of CB/SiO₂ approaches 1, and then it began to rebound with the ratio increase. Meanwhile, a characteristic Newtonian viscosity plateau appearing in low frequencies also significantly decreases, depending on the amount of CB or SiO₂ added. On the basis of a simplified Fowke model, we ascribe this phenomenon to the deteriorated filler network, which is predominantly induced by the totally different surface activity between CB and SiO₂. © 2006 Wiley Periodicals, Inc.

炭黑品种及用量对NBR/CHR并用胶性能的影响

研究了炭黑Ｎ６６０、Ｎ６３０、Ｎ７６２、天然气半补强炭黑及喷雾炭黑对ＮＢＲ／均聚氯醚橡胶（ＣＨＲ）并用胶性能的影响。试验结果表明，这些炭黑在ＮＢＲ／ＣＨＲ并用胶中的用量达到８０份时，并用胶的加工性能仍较好。随着炭黑用量的增大，ＮＢＲ／ＣＨＲ并用胶的耐四氯化碳性能提高；压缩永久变形、压缩温升及硬度增大；扯断伸长率和回弹值下降；而拉伸强度则是先升高，当炭黑用量达到６０份时即下降；撕裂强度也是先升高，而后在不同用量处出现下降趋势。     

Chemical Composition Determination at the Bottom Region of a Recovery Boiler Furnace by Direct Minimization of Gibbs Free Energy

An optimization strategy has been applied to describe the chemical composition at the furnace bottom in the Kraft recovery boiler of a pulp production process. The concentrations of each involved chemical species were calculated through an optimization approach, minimizing the Gibbs free energy of the system. Various systems were proposed and tested, assuming different chemical species and phases number. Because serious initialization problems were found at this stage for some of the proposed systems, an optimization heuristic method (PSO) was used for the first approach to the problem. Once the appropriate phases number and chemical species in the system were determined, the initialization problems disappeared and the use of a deterministic optimization method (SQP) became viable. The proposed approach has shown to be satisfactory to reproduce industrial data and also data reported in the open scientific literature.
