Effect of Mooney Viscosity,Temperature and Humidity on Cord Failure in Carcass Ply

阐明胶料门尼粘度及现场温度和湿度对胎体帘布稀线的影响。胎体帘布稀线是全钢载重子午线轮胎生产中比较常见的一种病象,造成胎体帘布稀线的影响因素除了帘布质量、胎体拼接质量、胎坯的储存和搬运外,胶料门尼粘度及现场湿度的影响也较大。胶料门尼粘度越高和现场湿度越低对胎体帘布稀线发生率的控制越有利。

The effect of Mooney viscosity, the temperature and humidity of workshop on the open cord failure in carcass ply was elaborated. This failure is very common in the truck and bus radial tire, which not only related to the quality of carcass ply, the splice quality, the storage and transport of green tire, but also was influenced by the Mooney viscosity of compound and the humidity. It was found that higher Mooney viscosity and lower humidity resulted in less failure.
