n.環(huán)烷

Experiments show that the two-polyurea grease with good reducing noise effect can be got with low viscidity cycloparaffin mineral oil as base oil and TDI,fat amic and cycloparaffin amic as ... 通過實驗證明,采用低粘度的環(huán)烷基礦物油作為基礎油,采用TDI、脂肪胺、環(huán)烷胺作為稠化劑,通過控溫慢冷和循環(huán)剪切方式,可以制得具有良好降噪聲效果的二聚脲潤滑脂。

For the quantitative analysis of normal paraffin hydrocarbons,isomeric paraffin hydrocarbons,olefin hydrocarbons,cycloparaffin hydrocarbons and aromatic hydrocarbons,the special software was used. 采用單體烴專用軟件實時采集處理數(shù)據(jù)，并可通過設定用戶參數(shù)完成催化裂化汽油中的正構烷烴、異構烷烴、烯烴、環(huán)烷烴及芳香烴的含量測定。
