25912.全球纳米材料市场报告(2014-2018年)
[化学原料和化学制品制造业,化学纤维制造业] [2014-08-29]
Nanocomposites are a class of materials that incorporate nano-sized particles in a matrix of other materials such as polymers. Such nano-sized particles enhance the properties of the matrix materials, including characteristics such as mechanical strength, electrical and thermal conductivity, and chemical resistance. Nanocomposites are used in a range of industries such as Building and Construction, Automotive, Aviation, and Healthcare.

25913.全球锆市场报告(2014-2018年)
[化学原料和化学制品制造业] [2014-08-29]
Zirconium (Zr) is a grayish-white chemical element, sourced from mineral zircon (ZrSiO4) sand. It is strong, ductile, malleable, and extremely resistant to heat and corrosion by other agents in nature. Zirconium is very weak in absorbing thermal neutrons; therefore, zirconium alloys are used in fuel cladding. Zirconium is widely used in various applications such as ceramics, chemicals,refractory, foundry, and television glass.

[化学原料和化学制品制造业,纺织服装、服饰业] [2014-08-29]
Laundry care products such as laundry detergents and washing powder are agents/surfactants developed to clean fabrics. These products contain a mixture of chemical compounds that are similar to soap but are less affected by hard water. These chemical compounds ensure the dirt is maintained in a dispersed condition and thereby prevent retention of the detached dirt by the fabric. Laundry care products include a variety of products such as liquid detergents, powder detergents, laundry tablets, fabric softener sheets, bleach, pre-wash additives, and liquid fabric softeners.

Exports of rubber and rubber products in China kept a 10% growth in 2013 while imports of them saw an 11.9% rise in last year.The capacity for TPU in China is expected to be 270 kt/a by 2018. The domestic demand will reach over 300 kt at that time. TPU sector will therefore still have a bringht prospect.

[化学原料和化学制品制造业] [2014-08-25]
The seeder of rice bud-seed for field seedling raising is a new seedling equipment for field seedling raising,which is a complicated vibration system with multi-freedom.And the effect of the vibration parameters and interactions on the vibration velocity at different locations of the moving rail of two electromagnetic vibration metering devices which are installed side by side is large,and the passing rate of seeding is affected.In this paper,the virtual prototype of seeder of rice bud-seed for field seedling raising is established by ANSYS and ADAMS.The virtual prototype is developed to carry out dynamics simulation by using four-factor quadratic regression orthogonal rotary combination design.Mathematical models of influencing factors of vibration and variation coefficient of vibration velocity,and the factors and average velocity of seeding are established.The factors are optimized.And optimal combination of vibration influencing factors and the variation coefficient of vibration velocity interval with 95% reliability are achieved.The result shows that optimal combination of factors is achieved under the condition that the excitation force amplitude is 39.8N,vibration frequency is 32.7Hz,the velocity is 58.5mm/s,stiffness of vibration isolating rubber pad is 1167N/mm.The corresponding variation coefficient of the vibration velocity is 6.287%,and the average seeding velocity is 18mm/s.The variation coefficient of the vibration velocity interval with 95% reliability is from 2.909% to 9.665%.

25920.硫酸盐轴承与土壤膨胀和橡胶技术可持续发展的最终报告
[化学原料和化学制品制造业] [2014-08-25]
The two main objectives of this research were (1) to propose a new subgrade soil stabilization protocol to allow CDOT and other transportation agencies to rely upon an alternative stabilization method that is not subject to the typical problems associated with calcium-based stabilization of sulfate-rich soils (the proposed technology is also appropriate to stabilize sulfate-free subgrade soils), and (2) to develop a new database of MEPDG parameters for local soil samples obtained from CDOT and to provide advanced testing and analysis of the stiffness degradation of these materials. The beneficial use of scrap tire rubber mixed with expansive soils is of interest to civil engineering applications since the swell percent and the swell pressure can be potentially reduced with no deleterious effect to the shear strength of the mixture.
