Abstract: Due to the unique properties of CNTs its own scientists called a "super fiber" has an attractive prospect in the high-tech fields. In recent years, the research center of gravity of the CNTs composites have been transferred to the polymer / CNTs composite materials, and has made great progress. CNTs and polymer composite, CNTs from nanometer to the actual operation of an effective and efficient use of the unique properties of CNTs can be achieved with the advantage of raw materials to complement or strengthen. Polymer composite materials have broad application prospects in information materials, biomedical materials, high-performance structural materials, multifunctional materials.

Abstract: The utilization of waste tire rubber powder processing complete sets of equipment there is imbalance problems. Tire tore cutter crusher production capacity surplus and large particles. Using small tires and non-free cutting tire for cracking machine in order to reduce the tire cracking machine and large particles of investment cost. Cracking down into tire surface rubber cut and tear broken tire surface rubber two process. Tire tread compound using cutting subdivision controlled again after cutting depth of rubber cutting block method. To tear cut machine tool feed depth is an effective method in control tire broken rubber block size. Tread colloid axial uniform circular cutting technical measures is to ensure that the plastic piece of particle uniform distribution.

Abstract: The social network community partition is conducive to obtaining hidden and valuable knowledge and rules, which is currently a hot research perspective. Traditional community mining often analyzes network structure information from a static point of view, but ignores the analysis of individual actors’ initiative, which limits the construction of community concept model and the effect of community partition. This article argues a method for community partition based on information granularity. First, we optimize the social relationship model by using the link prediction method and establish the similarity model of user social relationship. Second, aiming at the deficiency of K-means clustering algorithm and the defect of high dimension and sparsity of data, the principle of information granularity is introduced in user clustering analysis, and membership degree and generalized equivalence relation of user equivalence relation are given respectively. On this basis, we propose a social community partition method based on the information granularity. Finally, experiments show that, because of the effective integration of the important information of users’ social relations and the introduction of information granularity method, the proposed model obtains better I index, and Dunn index evaluation results compared with K-means.

Abstract: In this paper, nanosol of titanium dioxide was prepared by sol-gel method using tetrabutyl-titanate as a precursor. The Particle Size Analyzer test results showed that the average diameter of the particles was less than 10 nm, and most particle size ranged from 6nm to 16nm. The prepared mechanism was discussed and then applied to fixation of vegetable turmeric dyed tussah silk. The fixation results indicated that the rubber fastness and washing fastness increased remarkably and the K/S values changed a little.
