| 普通输送带执行GB7984-2001标准。 Conventional conveyor belts are in accordance with the GB7984-2001 standard. 普通输送带：覆盖层：拉伸强度不小于15Mpa，扯断伸长度不小于350%，磨耗量≤200mm3；层间粘合强度纵向试样平均值布层间不小于3.2N/mm；覆盖胶与布层间不小于2.1N/mm；全厚度纵向扯断伸长率不小于10%；全厚度纵向参考力伸长率不大于1.5%。 Common conveyor belt: covering layer: tensile strength not less than 15 Mpa, elongation at break not less than 350%, wear less than 200 mm 3; average interlaminar bonding strength of longitudinal sample cloth not less than 3.2 N/mm; covering glue and cloth layer not less than 2.1 N/mm; full thickness longitudinal elongation at break not less than 10%; full thickness longitudinal reference force elongation not less than 3.2 N/mm Greater than 1.5%. 尼龙（NN）、聚酯（EP）输送带覆盖层，拉伸强度不小于15Mpa，扯断伸长度不小于350%，,层间粘合强度纵向试样平均值布层间不小于4.5N/mm，覆盖胶与布层间不小于3.2N/mm,全厚度纵向扯断伸长率不小于10%，全厚度纵向参考力伸长率不大于4%，覆盖胶采用橡塑共混，骨架国标级别拉力强度系数，可以搭接成环形。 The overlay of nylon (NN) and polyester (EP) conveyor belts has tensile strength of not less than 15 Mpa, elongation at break of not less than 350%. The average interlayer bonding strength of longitudinal samples is not less than 4.5N/mm, the interlayer bonding strength is not less than 3.2N/mm, the longitudinal elongation at break of full thickness is not less than 10%, and the longitudinal reference elongation of full thickness is not less than 4.5N/mm. Over 4%, the covering rubber is blended with rubber and plastic, and the tensile strength coefficient of the skeleton can be lapped into a ring. |
