合成导热油的使用原理!

发布时间2019-07-25  来源:http://www.wunqdctk.com

  虽然我们使用的合成导热油性能相对较好,但不可否认的是,选择合成导热油也是一个原则。现在我们来谈谈合成导热油的使用原理。
  Although the performance of synthetic heat conducting oil is relatively good, it is undeniable that the choice of synthetic heat conducting oil is also a principle. Now let's talk about the principle of using synthetic heat conducting oil.
  1. 合成导热油导热系数大,比热系数高,热效率高,经济效益好。
  1. The synthetic thermal conductive oil has high thermal conductivity, high specific heat coefficient, high thermal efficiency and good economic benefit.
  2. 合成导热油具有良好的热稳定性和抗氧化稳定性。在最大允许使用温度下提供良好的热稳定性和抗氧化稳定性,使用寿命长。合成导热油是一种有机材料。无论是合成导热油还是矿物油导热油,它们都是烃类(烷烃、环烷烃或芳烃及其衍生物)。因此,在加热条件下,烃类会发生热裂解反应和氧化反应,使合成导热油变质。
  2. The synthetic heat conducting oil has good thermal stability and oxidation resistance. Provide good thermal stability and oxidation resistance at the maximum allowable operating temperature, long service life. Synthetic heat conducting oil is an organic material. Whether synthetic or mineral oil, they are hydrocarbons (alkanes, naphthenes or aromatics and their derivatives). Therefore, under heating conditions, hydrocarbons will undergo pyrolysis and oxidation reactions, which will deteriorate the synthetic heat conducting oil.
  热解反应生成低沸点物质。沸点低的物质还会发生聚合(或缩合),形成聚合物材料,如胶质,导致粘度增加和炭渣增多,会引起结焦。氧化反应产生有机酸,所以导热系数的合成油酸值增加,深度氧化也会产生不溶性酸污泥,因此合成导热油粘度增加的热油炉墙,但也增加了热阻,降低热导率。
  The pyrolysis reaction produces low boiling point substances. Low boiling point substances can also occur polymerization (or condensation), forming polymer materials, such as colloids, resulting in increased viscosity and carbon slag, which can cause coking. The oxidation reaction produces organic acid, so the acid value of synthetic oil with thermal conductivity increases, and insoluble acid sludge will also be produced by deep oxidation. Therefore, the thermal oil furnace wall with increased viscosity of synthetic thermal conductivity oil increases, but it also increases thermal resistance and reduces thermal conductivity.
  因此,在选择合成导热油时,对于矿物油导热油,应在基础油选择并精馏后加入多种复合添加剂的导热油。对于合成导热油也要了解其性能,一般来说,合成油的稳定性和氧化稳定性都比较好,但是由于价格较高,很多合成油仍然需要进口。
  Therefore, in the selection of synthetic heat conducting oil, for mineral oil heat conducting oil, the base oil should be selected and distilled and then added with a variety of complex additives heat conducting oil. Generally speaking, synthetic oil has good stability and oxidation stability, but because of its high price, many synthetic oils still need to be imported.
  3、应有高闪点、自燃点和沸点。导热油闪点高,自燃点高,可避免火灾隐患。液相导热油具有较高的沸点(初始沸点)和较低的低沸点含量,可以保证液相导热油的安全使用。闪点是导热油受热时,挥发出的油蒸气与周围空气混合,与明火接触时闪点的最低温度反映导热油的蒸发趋势。

  3. There should be high flash point, spontaneous ignition point and boiling point. High flash point and spontaneous ignition point of heat conducting oil can avoid potential fire hazards. The liquid phase heat conducting oil has high boiling point (initial boiling point) and low boiling point content, which can ensure the safe use of liquid phase heat conducting oil. The flash point is when the heat conducting oil is heated, the volatile oil vapor mixes with the surrounding air, and the lowest temperature of the flash point when it contacts the open fire reflects the evaporation trend of the heat conducting oil.
  导热油中,低沸点的作用容易蒸发,闪点高,相对安全。初馏点是指矿物油导热油中沸点最低的馏出物的最低温度。初馏点高,沸点组分含量低,使用时必须降低蒸汽压力,减少蒸发损失,并能保证最高的使用温度为液态。
  In heat conducting oil, the effect of low boiling point is easy to evaporate, high flash point and relatively safe. Initial distillation point is the lowest temperature of distillate with the lowest boiling point in mineral oil heat conducting oil. With high initial distillation point and low boiling point component content, it is necessary to reduce steam pressure and evaporation loss, and to ensure that the highest operating temperature is liquid.
  4. 合成导热油应具有较低的酸值和残炭。系统内的设备和管道材料不发生化学反应和腐蚀。导热油在高温下使用。导热油加热系统运行时间长,对系统材料和设备产生化学反应或腐蚀作用,设备和管道将提前报废。酸值是导热油中有机酸的总和。高酸值时,油中有微量水,会对设备造成腐蚀。残炭是导热油裂解产物聚合(或缩合)形成的一种胶质或沥青质。高含碳量会引起结焦,影响传热效果,严重堵塞设备和管道。
  4. The synthetic heat conducting oil should have lower acid value and carbon residue. No chemical reactions and corrosion occur in the equipment and pipeline materials in the system. Thermal conductive oil is used at high temperature. The heat conducting oil heating system runs for a long time and produces chemical reactions or corrosion effects on the materials and equipment of the system. The equipment and pipelines will be scrapped in advance. The acid number is the sum of organic acids in heat conducting oil. When the acid value is high, there is little water in the oil, which will cause corrosion to the equipment. Residual carbon is a kind of colloid or asphaltene formed by polymerization (or condensation) of pyrolysis products of thermal conductive oil. High carbon content will cause coking, affect the heat transfer effect, and seriously clog equipment and pipelines.
  综上所述,这些就是合成导热油的相关选择原则。希望您看到这些原理后能更好的选择合成导热油,以便我们使用。
  In summary, these are the relevant selection principles of synthetic heat conducting oil. I hope you can choose synthetic heat conducting oil better after you see these principles, so that we can use them.
