crosslinking density 中文意思是什麼
-
The experimental results further demonstrate that the combination of incompatibility polydimethylsiloxane and polyacrylate by co - vulcanization improves the both compatibility and broadens the low temperature and high temperature functional region. while in sin, to improve microphase structures and damping properties, the design to increase compatibility between two compositions and modulate crosslinking density as well as relative reaction rate of two compositions, is also effective
以上實驗結果表明，在復合橡膠阻尼材料中將聚硅氧烷與聚丙烯酸酯通過共混硫化相結合，改進了二者的相容性，拓寬了其阻尼功能區的低溫和高溫溫域；而在sin中通過改善組四川大學博士學位論文分間相容性，調節交聯密度控制其微相結構和兩種組分相對反應速度的快慢，進而控制材料阻尼性能的設計是行之有效的。 -
In addition, it has been found that the number of attached spores on the surface of ionic hydrogels was affacted by the crosslinking density of gels, but the germination ratio of attached spores and growth of gametes have nothing to do with the crosslinking density of gels
此外，離子型凝膠表面孢子的附著量受凝膠的交聯度影響，而孢子的萌發率以及配子體的生長發育均與凝膠的交聯度無關。 -
Two kinds of polyethylene were chose, which included : high - density polyethylene and crosslinking polyethylene
所選用聚乙烯分別是：高密度聚乙烯和交聯聚乙烯。 -
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
