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、傳熱性能如何:

　　A. How about the heat transfer performance?

　　1、耐高溫輸送帶不僅要在常溫下具有良好的耐磨性，而且要求在高溫條件下不變質(zhì)。

　　1. High temperature resistant conveyor belts should not only have good wear resistance at room temperature, but also not deteriorate at high temperature.

　　2、輸送帶耐高溫覆蓋磨損。

　　2. The conveyor belt is resistant to high temperature covering wear.

　　3、可長(zhǎng)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。耐高溫輸送帶用蓋膠:

　　King II. Cover glue for high temperature resistant conveyor belt:

　　橡膠:(epdm 200)耐高溫輸送帶上覆蓋橡膠，常用的橡膠品種有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.

　　目前使用多的是SBR，但僅適用于12O℃?為下列目的;IIR的耐高溫性能優(yōu)于SBR，但工藝性能較差，過高，在國(guó)內(nèi)使用較少。EPR耐熱性能和相對(duì)適中，適合生產(chǎn)耐熱輸送帶。

　　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耐熱性好，長(zhǎng)期使用也不易開裂，雖然受熱后硬度也提高，但提高程度遠(yuǎn)低于SBR，而硬度提高后，其耐磨性能仍有所提高。按照項(xiàng)目嗎?固化太慢，所以EPDM被用于生產(chǎn)。另外，有EPDM嗎?在大規(guī)模生產(chǎn)中，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.

　　硫化體系:氧化鋅20，硬脂酸2，硫粉5，氧化鎂??20.促進(jìn)劑M

　　Vulcanization system: zinc oxide 20, stearic acid 2, sulfur powder 5, magnesium oxide?? 20. accelerator M

　　過氧化物硫化橡膠耐熱性好，但硫化速度較慢。為了提高固化速度，可以加入少量的硫和促進(jìn)劑。

　　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.
