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 ... 通过实验证明,采用低粘度的环烷基矿物油作为基础油,采用TDI、脂肪胺、环烷胺作为稠化剂,通过控温慢冷和循环剪切方式,可以制得具有良好降噪声效果的二聚脲润滑脂。
For the quantitative analysis of normal paraffin hydrocarbons,isomeric paraffin hydrocarbons,olefin hydrocarbons,cycloparaffin hydrocarbons and aromatic hydrocarbons,the special software was used. 采用单体烃专用软件实时采集处理数据，并可通过设定用户参数完成催化裂化汽油中的正构烷烃、异构烷烃、烯烃、环烷烃及芳香烃的含量测定。
