To prepare the functionally gradient materials ( fgm ) of polysilane - polyacrylate , the method of solution preparation was performed . based on the results of the back - scattered electron images and linear scanning of the polysilane - polyacrylate film ' s cross section , the dependence of polysilane - polyacrylate film ' s structure on molecules of polysilane and polyacrylate , pmma / pmts feed ratio and component concentration were investigated 通過(guò)測(cè)試有機(jī)硅聚合物-聚甲基丙烯酸酯樹脂膜的結(jié)構(gòu),分析了聚有機(jī)硅( pmts ) 、聚甲基丙烯酸酯( pmma )的分子量、 pmma pmts體系配比、組分濃度等因素對(duì)有機(jī)硅聚合物-聚甲基丙烯酸酯樹脂膜結(jié)構(gòu)的影響。
According to the tests on ball - feed ratio , medium filling percent age , ground pulp density , active power and grinding efficiency , the authors anal yse main factors affecting ball mill s active power and grinding efficiency , es tablishing the relationship between ball mill s internal state ( such as ball - f eed ratia , medium filling percentage and ground pulp density ) and external param eters ( such as active power and grinding efficiency ) and giving appropriate oper ating parameters for improving grinding efficiency 通過(guò)對(duì)球磨機(jī)球料比、介質(zhì)充填率和磨礦濃度與有功功率和磨礦效率試驗(yàn),分析了影響球磨機(jī)功率和磨礦效率的主要因素,建立了球磨機(jī)內(nèi)部狀態(tài)(球料比、介質(zhì)充填率和磨礦濃度)與外部參數(shù)(有功功率、磨礦效率)之間的關(guān)系,提出了改善磨礦效率的合理操作參數(shù)。
