均匀设计在电梯导靴轮胶料硫化体系优化中的应用

Application of Uniform Design in Optimization of Curing System of Elevator Guide Wheel Compound

通过均匀设计试验研究硫化体系中硫黄和促进剂M用量对电梯(直梯)导靴轮胶料及成品性能的影响,并确定优化的硫黄和促进剂M用量。结果表明:与硫黄用量相比,促进剂M用量对胶料性能的影响更显著;促进剂M用量对混炼胶的t10和Fmax,硫化胶的硬度、拉伸强度、拉断伸长率和拉断永久变形,成品导靴轮的硬度和低频噪声影响显著;硫黄用量对硫化胶的硬度、拉伸强度和拉断伸长率,成品导靴轮的硬度影响显著;促进剂M用量取1~1.5份、硫黄用量取2~3份为宜。

The effects of the amount of sulfur and accelerator M in curing system on the properties of the compound and finished product for elevator(staircase) guide wheel were investigated by uniform experiment design,and the optimum amounts of sulfur and accelerator M were determined. The results showed that,compared with the amount of sulfur,the amount of accelerator M had more significant effect on the properties of the compound. The amount of accelerator M had a significant effect on various properties such as t10 and Fmax of the compound,the hardness,tensile strength,elongation at break and permanent deformation at break of the vulcanizate,and the hardness and low frequency noise of the finished guide wheel. The amount of sulfur had a significant effect on the hardness,tensile strength and elongation at break of the vulcanizate,and the hardness of the finished guide wheel. The optimum amount of accelerator M was 1~1. 5 phr and optimum amount of sulfur was 2~3 phr.
