Modèle: Rubber Lifting Belt
Description du produit
|
Rubber lifting belt is multi-layer silica gel fabric folded with cover rubber outside the belt core. It can be classified in heat-resistant lifting belt and common lifting belt as per application temperature while can be classified in full-cotton, Dacron and cotton, nylon and EP lifting belt as per core material. 1.Physical properties and level of cover rubber. It can be divided as type D for heavy-wear, type L for middle-wear and type T for high-temperature material conveyance as per wear and load of material. 2.Wide specification of lifting belt: 150 200 250 300 350 400 500 600mm etc. 3.Technical requirement of lifting belt. |

Remarks:Physical property of cover rubber will depend on if lift special material or acute wear material. 1.Cover rubber property of heat-resistant belt (T type) should accord with HG/T2297 (heat-resistant belt) standard. 2.Longitudinal tensile strength of belt should not lower than nominal value below: 100/ 125 /160/ 200 /250/ 315/ 400 /500N/mm . 3.Tensile yield of belt longitudinal thickness should not lower than 10% and reference elongation should not more than 4%. 4.Bond strength between layers of lifting belt with fabric core is listed as below: N/mm. |
