This paper present the optimum conditions for treating oily sludge with organic solvent extraction and surfactant solutions using the single factor experiment. Firstly, selecting petroleum ether (boiling range is 60-90oC) as the organic solvent, then selecting the mixture of sodium dodecyl benzene sulfonate and alkylphenol ether(OP-10) as surfactant agent to extract residual crude oil. Results obtained through experiments, the optimum parameters of petroleum ether were that ultrasonic reaction temperature was 55 oC, ultrasonic intensity was 320W, ultrasonic extraction time was 5min, liquid/solid mass rate was 7.5, then under the optimum conditions, the residual oil rate was about 6%. While the optimum parameters of surfactant mixture were that the temperature was 55 oC, ultrasonic intensity was still 320W, ultrasonic extraction time was 10min, liquid/solid mass rate was 15, under the optimum conditions, finally the residual oil rate was only about 1%.
nanoDiamond was mixed with ethylic cellulose and other Material to form to paste. A series of sol-gel nanoDiamond film with different proportions were designed test intentionally. nanoDiamond film was fabricated on Aluminum substrates using two-steps sintering process. The moving terminal of the variable super-capacitor was the shaft which throughout each of monolithic capacitor plate. The low melting point glass powder possesses giant permittivity, low dielectric loss, good thermal stability and dielectric constant in a wide temperature range which applied very broad prospects in microelectronics. The low melting point glass powder was mixed with carboxymethyl cellulose and deionized water to paste. The low melting point glass powder insulation thick-film was fixed on nanoDiamond film .In this paper, the insulation thick-film preparation: sintering at 578K to 588K and keeping 11.5 h to 12.5 h. A variable super-capacitor was designed based on nanoDiamond film electrode and low melting point glass powder insulation thick. Insulation thickness was prepared on uniform nanodiamond film to increase insulation super-capacitor between the two plates.
Nano-SiC was mixed with nanocrystalline graphite and ethylic cellulose to paste. In order to fabricate Nano-SiC film electrode of super capacitor, a series of sol-gel Nano-SiC film with different proportions are designed test intentionally. Nano-SiC film was fixed on metal substrates using three-steps sintering process. The perovskite structure CaCu3Ti4O12 (of CCTO) ceramics has giant permittivity, low dielectric loss, good thermal stability and dielectric constant in a wide temperature range has very broad application prospects in microelectronics. In this paper, the solid state reaction sintering can be divided into two categories: sintering at 1373K at different times; first heating to 1423K then immediately cooling to 1373K and keeping for different times. The CCTO ceramic dielectric constant and dielectric loss decreased with frequency rises. A super capacitor was designed based on CCTO ceramics dielectric and Nano-SiC film electrode.
In this paper, a novel light-absorpting shade and optical fiber and long persistent luminescent phosphor materials provided a safe and reliable day-and-night solar lighting system. It was not only save resource, reduce pollution, at the same time introduced solar light into the indoor to satisfy the lighting needs. The novel light-absorpting shade fabricated nanodiamond film to achieve the goal of self-cleaning,corrosion-resistant and corrosion-high temperature. This novel solar lighting system used of total reflection characteristic of optical fiber, and long persistent luminescent phosphor materials short storage time, high brightness to realize the purpose of day and night lighting.
Through continuous experiments, scientists have found that nanomaterials have self-cleaning properties. Solar cells coated with nanometer film can keep their surface clean for a long time and maintain high photoelectric conversion efficiency. nanodiamond films were prepared on glass substrate by sol-gel method. nanosilicon carbide was also selected as the contrast material. Silicon carbide (SiC) has good chemical stability, corrosion resistance and other characteristics. nanosic films were prepared by sol-gel method on glass substrate. The production cost of sol-gel method was relatively low, the coating uniformity was suitable for mass production
