Abstract: During rubber processing, many factors can affect the mechanical properties of rubber composite. The influence of ambient temperature and content of titanate coupling agent and modified attapulgite (OAT) on mechanical properties were investigated by preparing rubber composites and measuring. The results showed that the rubber composite which was filled 40phr OAT modified by 3% titanate and prepared at the ambient temperature above 20 had best tensile strength (18.93MPa). There is a special phenomenon that the tensile strength had a rapid increase from 4.72MPa to 18.93MPa, when the content of OAT changed from 20 to 40phr in the experiment.

Abstract: In this work, purified and surface-pretreated attapulgite was added to the common recipe of the skin-care cream and the improved cream products, containing clay minerals, were prepared. In order to optimize the moisturizing and sunscreen properties of the cream products, different attapulgite addition was tried and the grinding time of the attapulite was considered. The result shows that, by adding attapulgite clay, the moisturizing and sunscreen properties of the skin-care products can be improved respectively.

Abstract: By fitting calculation of functional relationship between charge quantity and temperature on condition that powders were shielded, a device was proposed to measure spontaneous polarity of powders, and samples of typical tourmaline were measured. The results showed when tourmaline powders of different origins were heated to 80, minimum value of spontaneous polarization strength was 3.204×10^-4C/m², and maximum value was 1.53×10^-3C/m². The conclusion was in accord with results got from crystal structure analysis, and repeatability r was 1.726×10^-6C/m² with 95% confidence probability.

Abstract: The test apparatus of infrared emissivity used in powders industry was researched by controlling the temperature accurately and collecting the signals of surface temperature of two standard samples and a test sample. The tourmaline samples from ten mines had been tested by the new test apparatus. Compared with the results from FTIR, it was shown that average value of relative error was 0.378% and repeatability error was less than 0.6% after correcting by the coefficient k_c = 0.958.

Abstract: Main evaluation methods of easy-to-clean property of domestic ceramics and sanitary wares were reviewed. Easy-to-clean technology meets the 21st century energy-saving industrial policies and will improve rapidly in new product development, evaluation techniques and standardization research.

Abstract: The main properties of tourmaline are far infrared radiation, spontaneous polarization, widely used in the fields of saving energy and environment. Tourmaline as catalyst have extensive applications in the fields of environmental protection, fuel combustion, air purification, printing, deodorant, antibacterial, as well as wastewater treatment of dyeing and aquaculture.

Abstract: Zeta potential of purified sepiolite in aqueous system was studied as a function of pH and solid content. From the experimental results, it was found that sepiolite surface acquired a negative charge in water at natural pH, and the value of zeta potential decreased with the increase of pH value. Solid content had effect on zeta potential, but it can be minimized by the increase of time.

Abstract: Activated water is beneficial to healthcare due to its changes of physicochemical properties compared to ordinary water. Some related researches on activated water are reviewed in this paper. Take magnetized water, mineral and ceramic activated water and electrolyzed water for examples, activating materials and technologies are briefly introduced. Then, mechanism of activation devices and activated water are summarized and discussed. Finally, mechanism of activated water on biological growth is analyzed by comparing their different properties.

Abstract: Cis-1,4poly-butadiene rubber (BR) is an unself-reinforce rubber. The tensile strength of BR is low. We study the factors that affect the capability of surface treatment attapugite/BR (OAT/BR). The factors include the kind of accelerant, the proportion of accelerant, the quantity of accelerant, the quantity of sulphur, etc. The result proves that the accelerant of CBS (CZ), TMTD, and TBBS (NS) can improve the capability of OAT/BR effectively. When the proportion of CZ and TMTD is 0.75 to 1.25, the quantity of accelerant is 3, the quantity of sulphur is 1.8, and the tensile strength of OAT/BR can reach 12.5MPa.

Abstract: The sepiolite samples were defibered by using microwave chemical technique, and then different sepiolite samples were obtained with different treatment process. The effect of reaction time on the defibering for sepiolite fiber bundles was studied systematically. Through characterization by scanning electron microscope (SEM), X-ray diffraction (XRD), Fourier transform infrared spectroscope (FTIR), it was found that the defibered sepiolite samples had an average diameter of about 100 nm and length greater than 20μm. The defibering effect of sepiolite samples as prepared reached optimum at the reaction time of 13 min, and the structural stability of sepiolite was kept after defibering treatment.
