从China供应商批发进口Parameters Of Cold-Resistant Conveyor Belts — FOB条款

The parameters of cold-resistant conveyor belts mainly include the following aspects: 1. Basic structural parameters Belt core material: cotton canvas, nylon canvas or polyester canvas is usually used as the belt core. Common belt core materials are NN100, NN150, NN200, NN250, NN300, NN350, NN400, NN450, NN500, etc. Bandwidth: The bandwidth range is usually between 100mm and 3000mm. Cloth layer: The number of cloth layers is generally between 1 and 10 layers. 2. Covering rubber parameters Working surface covering rubber thickness: The thickness of the working surface covering rubber is usually between 1.5mm and 8.0mm. Non-working surface covering rubber thickness: The thickness of the non-working surface covering rubber is usually between 1.5mm and 4.5mm. 3. Performance parameters Tensile strength: Different types of cold-resistant conveyor belts have different tensile strength requirements. The tensile strength of the scratch-resistant type (H) is not less than 24Mpa, the tensile strength of the wear-resistant type (D) is not less than 18Mpa, and the tensile strength of the general type (L) is not less than 15Mpa. Elongation at break: The elongation at break of the scratch-resistant type (H) is not less than 450%, the elongation at break of the wear-resistant type (D) is not less than 400%, and the elongation at break of the general type (L) is not less than 350%. Cold resistance: According to the different cold resistance performance, cold-resistant conveyor belts are divided into two levels, C1 and C2. The operating environment temperature range of C1 level is -45 to +45 (some say -45 to -50), and the operating environment temperature range of C2 level is -60 to +45 (some say -50 to -45). At the corresponding cold-resistant temperature, the change rate of tensile strength and the change rate of elongation at break must be within the specified range. In summary, the parameters of cold-resistant conveyor belts cover many aspects such as basic structure, cover rubber, performance and type. The selection of these parameters depends on the specific application scenario and requirements. Zaozhuang Jinfulex Rubber & Plastic Technology Co., Ltd. has 50 years of production experience.
