耐热输送带的耐热性是怎么样的?

来源:http://www.huafengxiangsu.com 时间:2019-09-09 13:46:55 浏览次数:
  今天我们带大家介绍一种输送带——耐热输送带。我们知道,有时候输送带的运输条件是非常苛刻的,比如高温物料的运输,如果输送带本身不耐热,很容易对输送带造成损坏,那么,输送带的耐热性是怎样的呢?
  Today we will introduce a kind of conveyor belt - heat-resistant conveyor belt. We know that sometimes the conveyor belt transport conditions are very harsh, such as the transport of high-temperature materials, if the conveyor belt itself is not heat-resistant, it is easy to damage the conveyor belt, then, what is the heat resistance of the conveyor belt?
  A、传热性能如何:
  A. How about the heat transfer performance?
  1、耐高温输送带不仅要在常温下具有良好的耐磨性,而且要求在高温条件下不变质。
  1. High temperature resistant conveyor belts should not only have good wear resistance at room temperature, but also not deteriorate at high temperature.
  2、输送带耐高温覆盖磨损。
  2. The conveyor belt is resistant to high temperature covering wear.
  3、可长期使用在150℃以上,也可短期使用在150℃以上。
  3. It can be used for a long time at above 150 C, or for a short time at above 150 C.
  二世。耐高温输送带用盖胶:
  King II. Cover glue for high temperature resistant conveyor belt:
  橡胶:(epdm 200)耐高温输送带上覆盖橡胶,常用的橡胶品种有SBR、IIR和EPR。
  Rubber: (epdm 200) High temperature resistant conveyor belt covered with rubber, the most commonly used rubber varieties are SBR, IIR and EPR.
大倾角输送带
  目前使用多的是SBR,但仅适用于12O℃?为下列目的;IIR的耐高温性能优于SBR,但工艺性能较差,价格过高,在国内使用较少。EPR耐热性能和价格相对适中,适合生产耐热输送带。
  At present, SBR is the most widely used, but only suitable for 12O (?) for the following purposes; IIR is superior to SBR in high temperature resistance, but its process performance is poor, the price is too high, and it is less used in China. EPR is suitable for producing heat-resistant conveyor belt because of its relatively moderate heat resistance and price.
  EPR耐热性好,长期使用也不易开裂,虽然受热后硬度也提高,但提高程度远低于SBR,而硬度提高后,其耐磨性能仍有所提高。按照项目吗?固化太慢,所以EPDM被用于生产。另外,中国有EPDM吗?在大规模生产中,价格比IIR便宜得多。
  EPR has good heat resistance and is not easy to crack in long-term use. Although the hardness of EPR is improved after heating, the degree of improvement is much lower than that of SBR, and the wear resistance of EPR is still improved after hardness is increased. According to the project? Curing is too slow, so EPDM is used in production. Besides, do you have EPDM in China? In mass production, the price is much cheaper than IIR.
  硫化体系:氧化锌20,硬脂酸2,硫粉5,氧化镁??20.促进剂M
  Vulcanization system: zinc oxide 20, stearic acid 2, sulfur powder 5, magnesium oxide?? 20. accelerator M
  过氧化物硫化橡胶耐热性好,但硫化速度较慢。为了提高固化速度,可以加入少量的硫和促进剂。
  Peroxide vulcanized rubber has the best heat resistance, but the vulcanization rate is slow. In order to improve the curing speed, a small amount of sulfur and accelerator can be added.
