热输送带

Heat Resistant Conveyor Belt

耐热输送带采用丁苯或三元乙丙橡胶为覆盖层，骨架材料采用专用的耐高温帆布，解决了高温环境下织物芯的收缩和变形问题，同时也避免了因乙丙橡胶饱和度高导致粘合性差、间层附着力低的关键问题。具有带体轻、寿命长（约2-4倍）、耐热性能好的特点。

Our heat resistant conveyor belt adopts SBR or EPDM as covering layer, special high temperature resistant canvas as carcass materials, not only solving the fabric shrinkage and deformation problems under the environment of high temperature, but also avoiding crucial problem as high degree of saturation of ethylene propylene rubber, poor adhesion. It is lighter, of long lifespan (about 2-4 times) and good performance of heat resistance.

产品特点

Product Advantage

1.规格同普通输送带相同。

2. 产品执行GB/T2002-2005 及GBAT7984-2001 标准，参考国际标准草案ISO/FDIS14890-1999。

3. 耐热输送带分为三种型号：

HR120:覆盖胶主要成分为SBR。可耐不大于120℃试验温度，瞬间运行温度170℃。该级别耐热带是比较通用的、较传统的耐热型输送带。广泛适用于水泥、焦化、冶金、化工、钢铁等行业使用。

HR150:覆盖胶主要成分为SBR。可耐不大于150℃试验温度，瞬间运行温度200℃。本产品与普通输送带相比具有耐热温度更高、抗龟裂、抗老化性能更好、寿命更长等特点。适于输送高热物料，如烧结料、水泥熟料、焦炭、干石灰、干燥白土等。

HR180:覆盖胶主要成分为EPDM。可耐不大于180℃试验温度，瞬间运行温度250℃。本产品与普通耐热输送带相比，具有优良的抗灼烧性能，在高温状态下胶带表面可迅速形成致密炭化层而达到隔热抗灼烧的效果，起到延长和提高使用寿命的目的。适用于温度较高如烧结矿、水泥矿等特殊运输场所。

1.Specification is similar to common conveyor belt.

2.GB/T2002-2005 and GB/T7984-2001 Standard are applicable with the international Standard draft ISO/FDIS14890-1999 as reference.

3.Heat resistant conveyor belt is divided into three types as follows:

HR120: cover consists mainly of SBR. The belt surface temperature of HR120 belt should be lower than 120℃,the maximum material temperature for short period can reach 170℃. This grade of Heat resistant conveyor belt is  mostly common used traditional heat resistant conveyor belt, widely used in Cement, coking, metallurgy, chemical,iron and steel industry, etc

HR150: cover consists mainly of SBR. The belt surface temperature of HR150 should be lower than 150°C,ａnd the maximum material temperature for short period can reach 200℃. Comparing to common conveyor belt, the product is higher temperature resistant, cracking resistant, ageing resistant and of long lifespan. It apply to transport high temperature material as sintered ore, clinker, coke, dry lime, dry clay, etc.

HR180: cover consists mainly of EPDM. The belt surface temperature belt of HR150 should be not higher than 180℃, and the maximum material temperature for short period can reach 250℃,Comparing to common conveyor belt, this kind of belt is more cauterant resistant. It forms a dense carbonized layers on belt cover under high temperature to play an effect of heat insulation and cauterant resistance , which can also extend the belt life . It apply to transport high temperature material as special transport situation as sintering ore and cement field , etc.

耐热输送带的选用

The selection of  heat resistant conveyor belt

依据耐热输送带所输送物料的温度、表面结构形状及粘度等参数选择耐热带的类型。如当输送温度为150℃的烧结矿石等大块物料，并且物料与带面接触面积较小时，带面温度保持在60-80℃;当输送水泥粉等粘度较小的物料时，物料温度与带面温度相差就很小。更多信息可参照下表：

Select different type of heat resistant belt according to the temperature, surface figure, viscosity condition and other concerned data of conveyed materials. For instance, when conveyed material have a temperature of 150℃,such as the coke or sintered ore etc, and have a relatively small contact area with the belt's surface temperature remains at 60-80℃. In contrast, when powdered material like cement is being conveyed, there is almost no temperature difference between material and belt surface. More information please refer to the following table.
