The model of heat conduction oil, the basic parameters

                                   The model of heat conduction oil, the basic parameters

A, model paraffin base (including methyl, ethyl, isopropyl) combined with benzene product. Its boiling point at 170 ~ 180 ℃, the solidifying point under - 80 ℃, it can be used antifreeze.

Type 2, alkyl naphthalene heat conduction oil. The additional amount and type of side chain shaped the nature of the compounds. Side chain khan methyl linked alkyl naphthalene, applied to the range of 240 ~ 280 ℃ by gas heating system.

3, alkyl biphenyls type heat conduction oil. It is composed of short chain alkyl (ethyl, isopropyl) combined with biphenyl ring structure, the amount and type of alkyl determine its nature. Paraffin base number, the more its thermal stability is poor.

4, biphenyl and diphenyl ether eutectic mixture type heat conduction oil. Such products because there is no connection with paraffin base side chains on the benzene ring, and the best heat resistance in the organic heat carrier. This kind of solidifying point (12.3 ℃), eutectic mixture at room temperature, boiling temperature within the range of 256 ~ 258 ℃ using more economic.

5, alkyl diphenyl ether type heat conduction oil. Such hybrid heat conduction oil viscosity under low temperature is low, liquidity is good, suitable for northern cold region, it is recommended to use temperature is highest do not exceed 330 ℃, solidifying point - 54 ℃.

6, mineral type heat conduction oil. A distillation range products are oil refining process, its main ingredients with base oil composition is different. As a general rule, be a mixture of long chain alkane and naphthene.

Second, the basic parameters

Viscosity, main steam pressure, boiling range, initial boiling point, flash point, ignition point, pour point, etc.

The main features

1, within the scope of permissible temperature, better thermal stability, coking, a longer service life.

2, within the scope of permissible temperature, thermal conductivity, good flow property and can pump performance.

3, low toxicity, no corrosion of equipment, little impact on the environment.

4, a low freezing point, high boiling point, low boiling point components in less. Within the scope of permissible temperature, vapor pressure is not high, less evaporation loss.

5, temperature higher than 70 ℃ when in contact with air oxidation will be strong, the heat work system need to seal, and its temperature under 70 ℃ is allowed only in contact with air.

6, after heated volume expansion, expansion rate greater than the water. Temperature of 100 ℃, the volume expansion rate can reach 8% ~ 10%.
