Study on Lubrication Properties of Emulsion for Aluminum Cold-rolling Wenxia Wang1,2,a,Ping Liu2,b and Guoqiang Yao2,c 1Shanghai University ,School of Mechanics Engineering and Automation, Shanghai 20072,China 2Shanghai Second Polytechnic University, Electrical and Mechanical Engineering Faculty, Shanghai 201209, China awxwang@meef.sspu.cn, bliuping@meef.sspu.cn, cgqyao@meef.sspu.cn Keywords: Aluminum cold rolling ; Emulsion lubrication; Lubrication model.
This paper’s work is to illustrate the mechanism and properties of emulsion lubrication.
Otherwise, stability is the most important factors to keep the application period of emulsion, and whether water and oil is emulsified well depends on the emulsifier.
In the earlier studies, much work was done on the viscosity of lubricant, but viscosity could not explain the lubrication properties of point contact lubrication.
The factors which lead to film failure includes roughness, non-Newton lubricant and temperature.

In the spring after clay thawing, sticky lower and internal friction Angle increases, make mechanical properties of soil before and after freeze-thaw changes, directly affect the anchor pile bearing capacity[2,3].
This paper apply numerical simulation method, this paper analyzes the pile in melted soil foundation resistance of the properties of bearing pull, used for workover piling in spring. 1.
(2) For the frozen soil will melt in spring, the resistance performance of working derrick anchor piles is greatly affected.

Box 1320, Kiryat- Gat 82109, Israel Tel: 972-8-6660000 aafreilik@micron.com, brshemto@micron.com, cyshor@micron.com Keywords: Queue Time; Methodology; Die yield; Process step; Algorithm; Correlation Abstract: Queue time (QT) between consecutive process-steps is one of the factors affecting the quality of current products in semiconductors industry.
It is influenced by several factors [1]: process variation during the production line (e.g mask misalignment); environmental – variation during circuit operation (e.g temperature fluctuations); systematic variation as metal dishing or lithography proximity effect; random variation, as material variation; design related issues etc.
In addition, the algorithm can be applied on any parametric response, as layer thickness, other layer properties, defect count, etc.

The ageing coefficients were calculated according to the relationship between the tensile strength and elongation at break changes, resulted as the effect of climatic and UV factors, and related to the same mechanical properties before the ageing processes.
The enhanced mechanical properties of silica-filled-POSS/HNBR composites are likely due to the increased dimensionality of the octafunctional POSS molecules.
A number of studies on POSS nanoparticles successfully incorporated into various polymers with the goal of modifying mechanical or thermal properties have been reported.
Compared to the initial properties of the studied elastomeric composites, placed in Table 2, it is clearly observed that generally both the climatic and UV ageing affect the adverse changes in mechanical properties, revealed as increse of rigidity and reduced elasticity coupled with lower strength of some samples.
The observed improvements in mechanical properties can likely be attributed to the increased dimensionality of the POSS cross-linker.

During polymerization process, the synthesis parameters such as Si/Al ratio, solid/water ratio, alkali concentration, curing temperature and curing time determine the final properties of geopolymer material [2].
Then species react with each other and undergo a polycondensation reaction to form a polymer network [3].So far the effects of NaOH concentration on the physical and mechanical properties of concrete are reported, where geopolymer is used only as a binder in the presence of sand and aggregates.

In order to predict the effective properties of PMR-15/T650-35 composite ply in the temperature range [250-350°C], the time-dependent mechanical properties of PMR-15 matrix determined experimentally [1], were considered.
The mechanical properties of the fibers do not experience any change due to the aging process in such a temperature range [2, 3].
Consequently, the corresponding macroscopic thermal and hygroscopic properties will be affected, also.
The magnitude of the effective properties remains similar, however.
The macroscopic hygro-thermo-mechanical properties were evaluated numerically using the viscoelastic Eshelby-Kröner self-consistent scale transition model.
