功能型负离子壁纸的制备和研究

功能壁纸因其绿色环保、功能性强等特性已成为新型的居家壁纸装饰材料。通过研究负离子粉体,制备了负离子涂料,并将该涂料涂布于壁纸表面,制备出负离子涂料壁纸;通过研究负离子纤维,并以该纤维作为主要原料按照壁纸的抄造工艺制备出负离子纤维壁纸。结果表明,两种功能壁纸的基本物理性能可满足壁纸优等品的国家标准;负离子释放量分别为3800个/cm~3、4800个/cm~3;甲醛去除率均可达92%;经过紫外线老化实验后,负离子释放量分别下降15.2%和23.5%;年辐射量均低于3 m Sv,均在人体每年所吸收空气和地表的辐射范围内。     

Cyber House Rules: James Law Cybertecture International

After training at the Bartlett in London and an influential period working in Itsuko Hasegawa's studio in Tokyo, James Law returned to launch his own practice, James Law Cybertecture International, in Hong Kong. Working globally and across media and disciplinary lines, Law has captured the imagination of his home country - he was recently awarded the Microsoft/Esquire ‘Cool Guy Digital Lifestyle Award 2006’ by the general public as the personality most symbolic of the new digital lifestyle of Hong Kong. Anna Koor puts Law's brand of ‘cybertecture’ under the spotlight and describes the mechanism of his uniquely responsive practice. Copyright © 2006 John Wiley & Sons, Ltd.     

Evaluation of VOC emission and sorption characteristics of low-VOC adhesive-bonded building materials

To reduce the risk of indoor air pollution caused by synthetic building materials, low-volitile organic compounds (VOC) building materials, including adhesives, are commonly used in building construction. Although adhesives do not directly contact indoor air, they affect VOC mass transfer at the surface of finishing materials by diffusion. This study investigates VOC emission and sorption behaviors of building materials with low-VOC adhesives. Small chamber emission and sorption experiments were designed in parallel to field measurements to examine the onsite VOC emission and sorption rates of adhesive-bonded building materials. It was found that the onsite emission rates from a wallpaper composite (polyvinyl chloride wallpaper?+?paper adhesive?+?gypsum board) were higher than the emission rates detected in the small-scale chamber, which demonstrates the possible sorption effect of the wallpaper composite. The results of the sorption chamber experiment confirm that the wallpaper is a sorptive building material and that the bonding of wallpaper to gypsum board increases the sorption and re-emission rates. These results indicate that even though low-VOC adhesive-bonded materials are used, additional indoor air quality control techniques should be applied to minimize re-emission by sorption processes over long periods of time.

改性TiO2的制备及其在壁纸中的应用研究

以纳米TiO_2 (P25)为改性对象,通过简单的一步水热法制备了具有可见光催化活性的N掺杂改性P25光催化剂 (N-P25),借助X射线衍射仪、紫外-可见光谱仪和扫描电子显微镜对N-P25的结构进行表征;再将其涂布于壁纸上,通过对壁纸物理性能和光催化降解甲醛性能的综合对比选择最佳涂布工艺。结果表明,N-P25仍为混晶结构,但对可见光的响应得到提升。在最佳涂布工艺条件下,N-P25涂布量1. 5g/m~2的壁纸在日光灯照射6 h后,对甲醛的降解率可达87%;且对不同初始浓度甲醛的光催化降解符合LH一级反应动力学规律。     

Techniques of Wallpaper (Biao Hu) in the Palace Museum: A Case Study of the Lodge of Bamboo Fragrance (Zhuxiang Guan)

Biao Hu was one of the eight famous traditional crafts in the late Qing dynasty. This skill involved decorating the interiors of ancient buildings such as ceilings, walls, and windows and creating burial objects. It was primarily used for wooden buildings in northern China during the early Qing dynasty. For example, there is white-patterned wallpaper in the Forbidden City utilizing both traditional and nontraditional patterns. Moreover, there was wallpaper with a special pattern in the Lodge of the Bamboo Fragrance (Zhuxiang Guan). Its structure and composition were studied via morphological observations and spectral analyses, the pigments and dyes were analyzed by Raman spectroscopy and ultra-high performance liquid chromatography-mass spectrum (UPLC-MS). Traditional technology and exchanges between China and the West were discussed by the study of patterned wallpapers in other buildings of the Forbidden City.
