The modification technology of the nano-CaCO3 was studied through orthogonal experimental methods. The factors studied were rotation speed, modifier dosage, emulsification temperature, emulsification time and heat aging time after emulsification. Optimized conditions for modification of the surface were： rotation speed 16000 r/min; modifier dosage 3%; emulsification temperature 75 ℃; emulsification time 60 min and aging time 40 min. The modified nano-CaCO3 was also studied by size-distribution measurements, transmission electron microscopy, infrared spectroscopy and thermal analysis. The results show that the size distribution of the modified nano-CaCO3 is uniform and that there are chemi-sorption and physi-sorption between the nano-CaCO3 and the modifier. Compared to traditional architectural coatings without nano-CaCO3, the nanometer composite coatings are obviously improved in respect to dirt resistance, scrub resistance, thixotropy, water resistance, alkalinity resistance and aging resistance.展开更多

Besides a large amount of sinsle color damask silk, many pattern woven silk including dragon robes, patterned costumes and luxurious silk textiles are found in complicated and colorful pattern woven brocade called zhuang hua. It was prevailed in Ming dynasty when compared with the frequency of the name chuang hua recorded in related historical documents. These pattern silk and brcrade were produced by the advanced pattern weavin8 technology, which was well developed in Ming dynasty. From historical documents of＂Tian gong kai wu＂, Exploitation of the works of nature, there is the detailed description of the draw loom （hua Io ji） which can weave normal patterned textiles. It also indicated that to produce dragon robes needed much more high technique, similar to the hua Io ）i but more complicated and difficult. A big draw loom is found to weave Nanjing Yen brocade today inherits the technolosy to weave zhuang hua brocade. After sorting the historical documents, it is found that some records are coincident with the existed materials, both the silk textiles and weaving technology. With these evidences research and exploration, this dissertatien tries to unravel the pattern weaving technolosy in the Ming dynasty.展开更多

Along with the development of Chinese character information processing technology, the modem computer techology has been penetrated into every field of society, it has been very important in the field of the design to implement font design and application using the computer directly. In this paper, the application of Chinese calligraphy fonts to the modem design art is discussed from computer font design and the components of Chinese characters, development trend, and modem decoration design. Calligraphy font design will be applied to more design areas, and also will be penetrated into all aspects of people＇ s daily life.展开更多
