chain density 中文意思是什麼
chain density
解釋
鏈密度-
Along with industrial value chain extending, cluster network density and network latitude also change, and in order to provide the convenience of communication, network interface also becomes better and better, which not only develops vertical network, but also breeds auxiliary network and horizontal network
隨著產業價值鏈的延伸，集群的網路密度和網路緯度也在變化之中，為方便各生產環節的交流，網路界面也得到完善和發展，這不僅發展了垂直網路，也催生了輔助網路和水平網路。 -
Silylate - terminated polyurethanes with built - in hydrophilic sites were synthesized. when the polymer is dispersed in water, the silane alkoxy end - groups of the polymer undergo hydrolysis, followed by condensation to form a stable cross - linked aqueous dispersion. tem studies indicated that with more incorporation of hydrophilic sites, the particle size of the dispersion decreased. it was also found that the film property depended on the particle size when the crosslinking density in particels was much higher. the average molecular weight of the elastically effective network chain mc measured by swelling experiments shows fairly good agreement with the theoretical value of mc. it was also found that the cross - linking density of the casting film may increase during the film formation and drying process
將硅氧烷封端的含親水基團的線性聚氨酯預聚體分散於水中，獲得穩定的聚氨酯分散體.由於硅氧基團水解、縮合，在分散體粒子內產生擴鏈交聯反應，生成了交聯水基聚氨酯分散體.透射電子顯微鏡研究表明分散體粒徑小、分佈寬.掃描電子顯微鏡研究了成膜結構及成膜性能與粒徑的關系.溶脹實驗計算獲得的兩交聯點之間的平均分子量與理論平均分子量相符.研究還發現此分散體膜在乾燥過程中可進一步交聯.膜的水溶脹及機械性能表明，此分散體具有極大的工業應用價值 -
In this paper, high density polyethylene / bentonite nanocomposites were prepared by simple melt compounding, their structures were demonstrated with x - ray diffraction, ft - ir spectra and dta. it was proved that the molecular chain of pe could be intercalated in layered silicate of organobentonite ， the intercalation nanocomposites were obtained
本文採用簡單熔融插層復合法制備高密度聚乙烯/膨潤土納米復合材料，用x -射線衍射、紅外光譜和差熱分析等手段表徵了復合材料的結構，證實聚乙烯分子鏈確已進入有機膨潤土的硅酸鹽片層間，形成插層型納米復合材料。
