有关尼龙的技术研究及改性技术资料分析

PAS／UHMWPE共混物 天津科技大学采用自制甲基丙烯酸缩水甘油酯接枝高密度聚乙烯（HDPE—g—GMA）作为增容荆来增容PA6／超高分子量聚乙烯（UHMWPE）共混物。HDPE—g—GMA对PA6／UHMWPE增容作用明显，使其冲击强度提高1倍，断裂伸长率提高3％。     

壳聚糖-淀粉-聚乙烯醇共混膜的制备及透光性研究

以溶液共混的方法制备了壳聚糖-淀粉-聚乙烯醇共混薄膜．考察了壳聚糖含量、聚乙烯醇和淀粉比例、增塑剂和交联剂含量对共混薄膜透光性的影响：实验表明：壳聚糖的加入可以显著提高共混膜的透光性，提高聚乙烯醇和淀粉比例能够改善共混膜的透光性，适量的增塑剂和交联剂能够改善共混膜的相容性、提高薄膜的透光率。     

纳米改性内外墙涂料

一．技术名称纳米改性内外墙涂料 一、成果简介纳米粉体作为纳米科技的重要组成部分，其制备过程正在不断成熟，但如何应用于传统产业的提升是当前广泛关注的研究课题。据统计，我国的涂料产量已位居世界前四位，但涂料行业的问题仍然十分突出。目前，国内建筑涂料普遍存在开罐效果差、贮存稳定性不好、耐擦洗性能较差、外墙涂料抗污染能力不高、易分层、易脱落、粉化、褪色、老化等缺陷，这些都急待克服解决。因此，将纳米材料应用于建筑涂料的改性研究，提高其技术含量，势在必行。

The Bisphosphonate Clodronate Modifying Hydroxyapatite Bioceramics for Bone Scaffold

To investigate the efficiency of clodronate modifying HA bioceramics,and to evaluate the effect of clodronate modifying HA bioceramics on the cells in vitro,clodronate modified the porous HA bioceramics for bone scaffold by chelation .The outermost layer of the specimens was analyzd by XPS and FI-IR ,The depth profile was investigated by the argon-ion sputtering method.The cell culture test was conducted using MC3T3-E1 osteoblastic cells,The cells were inoculated and cultured on the scaffolds.Morphological observation of the cells,MTT test and ALP activity test evaluated the cell attachment ,proliferation and activity on the scaffolds.The cell culture test in cell quantity and morphology indicated active proliferation of the cells on the scaffolds.The ALP activity of the cells cultured for 3d and 7d on clodronate-HA bioceramics was slightly higher than that on HA bioceramics ,but the difference was not signifcant,This result indicated that clodronate-HA bioeramics had favorable cytocompatibility to be used as bone scaffold with potential ability to improve asteogensis.     

F级THEIC－亚胺改性聚酯漆包扁线的研制

研制的Ｆ级ＴＨＥＩＣ－亚胺改性聚酯漆包扁线漆，工艺适应性强，工艺幅度大；漆层易于涂匀涂厚，确保扁线圆角处涂层厚度；可采用现有工艺、设备涂制漆包扁线，而且也适用涂制Ｆ级漆包圆线。用它生产的Ｆ级漆包扁线，具有良好的综合性能；击穿电压高而且存放期间较稳定；耐热冲击性能及弯曲性能好；能与热固性浸渍漆相容；价格较低。经实际应用证明，它不失为目前国内Ｆ级电机电器用的优良漆包扁线品种。
