What's the difference between asphalt oil and rubber oil?
(1) low temperature asphalt (Ruan Liqing), global softening point of 35~75 degrees celsius:(2) medium temperature asphalt, softening point of global law is 75~95 degrees celsius;(3) high temperature asphalt (Ying Liqing), global softening point of 95~120 degrees; in addition, according to user requirements, coking plant can produce softening point is 120~250 degrees of high temperature asphalt.(4) modified asphalt.
Asphalt should be liquid, can flow, but viscosity coefficient is too large [1]), heating to a certain temperature, that is, softening state, according to the softening point of the difference
Yes, there are many plastic pipes on the roof, and the water around the pipe needs asphalt oil!Coal pitch is a dark liquid with a volume density of 1.25 to 1.35g/cm3 at room temperature (bitumen is liquid, not solid, although it looks solid
The modified asphalt is made from Wen Liqing in china. In ordinary medium temperature asphalt, benzene insoluble BI is about 18%, quinoline insoluble fraction, QI is about 6%. When the asphalt is treated with heat, hydrogen molecules, methane and water are produced by chemical reactions in the process of thermal shrinkage of aromatic molecules in asphalt. At the same time, some of the original beta resin in the asphalt is converted into two times of alpha resin, part of the benzene dissolved into beta resin, the alpha component is greatly increased, the cohesiveness is greatly increased, and the asphalt has been modified. This kind of bitumen is called modified bitumen.
A high temperature asphalt called softening point above 135 DEG C is required to be used as a binder for the taphole material of blast furnace taphole.In order to improve the elasticity, flexibility, workability and compatibility of rubber, it is necessary to add specific rubber oil to achieve the purpose. In the actual use of rubber oil, because of different uses, the use of different industries, the physical properties of rubber oil requirements are many specific differences, so it has derived many names and brands.
