The results showed that the content of aromatics in the feedstock and the structural characteristics were the key factors which influencing the performance of the asphaltic resins.
原料中的芳烃含量及结构特点是影响沥青树脂性能的关键因素。
Install, repair or replace single-ply roofing system using waterproof sheet materials such as modified plastics, elastomeric or other asphaltic compositions.
使用防水片材,如改性塑料,橡胶或其他沥青成分安装,维修或更换单层屋面系统。
In this way, the vacuum gas oil or spindle oil and the lubricating bases are separated by means of lateral extractions while an asphaltic component or fuel oil is separated at the base.
用这种方法可以通过侧线采出分离出真空瓦斯油或锭子油和润滑基础油,同时在底部分离沥青组分或燃料油。
While each lubricant manufacturer may have a unique product formula, all of the semifluid products now start with a viscous base oil versus the asphaltic material that used to be the starting point.
Diagenesis data indicate that the Silurian asphaltic sandstones are the products of multiple fillings of hydrocarbon.
志留系沥青砂巖的成巖作用特征等资料证明,沥青砂巖的形成是烃类多期次注入的结果。
High asphaltic concrete core dam is one of the new developing directions in dam construction of the world. It is important to study the parameters back analysis.
Crude oil that has been generated by relatively high temperatures in the oil window. Mature oil contains lower molecular weights and less asphaltic compounds. It has high API.
在油窗内由相对高温所生成的原油。成熟油含有较低的分子重量和较少的沥青成份。有高的API。
In most cases, the end result of a proper semi fluid OGL application will look much like an old asphaltic solvent cutback application, but appearances will vary between manufacturers.
The construction was supervised at job site, and an asphaltic concrete laboratory was set up for monitoring the construction quality, in order to guarantee the high construction quality.
现场施工采取「旁站」监理方式,并建立沥青混凝土试验室对施工质量进行跟蹤检测,保证了施工质量。
Since asphaltic concrete materials are temperature dependent in nature, measured deflections and hence the structural capacity of pavement vary with temperature.
由于沥青混凝土材料强度的温度依赖性,弯沉以至路面结构承载能力都随温度而变化。
Depending on the characteristics of the residual oil and the length of the blowing time, asphaltic materials of varying characteristics are produced.
