1. According to the size of the volume of transport by width.

2、按使用环境的不同，分为橡胶输送带又包括（普通型、耐热型、难燃型、耐烧灼型、耐酸碱型、耐油型）、耐热输送带、耐寒输送带、耐酸碱输送带、耐油输送 带、食品输送带等型号。其中普通输送带 和食品输送带上覆盖胶厚度为3.0mm，下覆盖胶为1.5mm；耐热输送带、耐寒输送带、耐酸碱输送带、耐油输送带上覆盖胶 厚度为4.5mm，下覆盖胶为2.0mm。根据使用环境的具体情况可按1.5mm来增加上下覆盖胶的厚度。

2. According to the different use environment, it can be divided into rubber conveyor belt (common type, heat-resistant type, flame-retardant type, burning resistant type, acid and alkali resistant type, oil resistant type), heat-resistant conveyor belt, cold resistant conveyor belt, acid and alkali resistant conveyor belt, oil resistant conveyor belt, food conveyor belt, etc. The thickness of upper covering glue is 3.0 mm and the thickness of lower covering glue is 1.5 mm for ordinary conveyor belt and food conveyor belt; The thickness of the upper covering glue is 4.5mm and the lower covering glue is 2.0mm for the heat-resistant conveyor belt, cold resistant conveyor belt, acid alkali resistant conveyor belt and oil resistant conveyor belt. According to the specific circumstances of the use environment, the thickness of the upper and lower covering glue can be increased by 1.5mm.

⒊按照橡胶输送带布层拉力强度分为普通输送带、强力输送带。强力型的帆布橡胶输送带分为尼龙橡胶输送带（NN输送带）和聚酯橡胶输送带（EP 输送带）。

3. According to the tensile strength of rubber conveyor belt, it can be divided into ordinary conveyor belt and strong conveyor belt. Strong canvas rubber conveyor belt is divided into nylon rubber conveyor belt (NN conveyor belt) and polyester rubber conveyor belt (EP conveyor belt).

橡胶层用途：

Application of rubber layer:

1：保护内置骨架强力层，避免受到输送物料的损伤。

1: It can protect the strong layer of the built-in framework to avoid the damage of the conveying materials.

2：根据不同物料性质，调整橡胶层性能更有效的保证输送带使用，延长寿命。

2: According to the properties of different materials, adjust the performance of rubber layer, more effectively ensure the use of conveyor belt, prolong the service life.

强力骨架层用途：

Application of strong skeleton layer:

1：提供输送带的承托物料的刚性。

1: Provide the rigidity of the supporting material of the conveyor belt.

2：有效保证承托物料的重量，提供有效的输送能力。

2: Effectively guarantee the weight of the supporting materials and provide effective conveying capacity.

3：有效的保证输送物料的生产安 全性。

3: Effectively ensure the production safety of conveying materials.
