输送带的覆盖胶采用天然橡胶、合成橡胶、天然橡胶和合成橡胶的混合物或各种合成橡胶的混合物制成，目的是为了使覆盖胶具有最好的抗切割和耐磨蚀的综合性能。

Transport cover tape is made using a mixture or a mixture of all kinds of synthetic rubber, natural rubber, synthetic rubber, natural rubber and synthetic rubber, in order to make rubber covered with synthetic properties, anti cutting and abrasion of the best.

输送带覆盖胶质量的选择决定输送带的性能及用途。I类输送带有很好的抗切割和抗撕裂性、耐磨性、耐油性极好，不推荐用于输送大块矿石，锋利的切割性物料，用于极其恶劣的工作条件。

The choice of the quality of the belt covering rubber determines the performance and application of the conveyor belt. Class I conveyor has excellent resistance to cutting and tearing, abrasion resistance, and excellent oil resistance. It is not recommended for conveying large pieces of ore, sharp cutting materials, and for extremely harsh working conditions.

输送带的覆盖胶采用天然橡胶、合成橡胶、天然橡胶与合成橡胶的混合物或各种合成橡胶的混合物制成。II类输送带的覆盖胶具有良好的耐磨性，但抗切割性和抗凿蚀性不如I类输送带高。不推荐用于输送切割作用不大的具有磨蚀性的经过筛分的物料，用于繁重的工作条件。

The covering rubber of the conveyer belt is made of a mixture of natural rubber, synthetic rubber, natural rubber, synthetic rubber or various synthetic rubber. The covering rubber of class II conveyor belt has good wear resistance, but its cutting resistance and corrosion resistance are less than those of I conveyor belt. Abrasive, sieving material that is not used for conveying cutting purposes is not recommended for heavy working conditions.
