道康宁润滑系在轮胎硫化中的应用及改进

Application of Dow Corning′s Lubricant System to Tire Vulcanization

介绍了采用ＤＣ３２８９润滑系作为隔离剂和脱模剂在轮胎硫化中的应用及改进情况。在双模定型硫化机硫化中，采用ＤＣ３２８９润滑系作为隔离剂，选择合理的催化剂ＤＣ６２用量及涂刷方法，可以解决钢模结垢问题。在硫化罐硫化中，采用ＤＣ３２８９稀释液作为隔离剂，可以彻底消除“白粉”现象，提高轮胎外观质量，大大降低成本。在这两种硫化方式中采用ＤＣ３２８９润滑系，可以减少圈弯损伤和胎体变形等副次品，具有明显的经济效益和社会效益。

The application of DC 3289 lubricant system to the tire vulcanization as isolating and releasing agent is described.The deposit on the steel mold can be eliminated by using DC 3289 lubricant agent as isolating agent,suitable level of DC 62 catalizing agent and right application method in the double tire press vulcanization.The white spot can be thoroughly eliminated,thus the tire appearance is improved and the production cost is reduced by using DC 3289 dilute solution as releasing agent in the autoclave vulcanization.The substandard products due to bent bead or carcass deformation etc. are reduced by using DC 3289 in both cases.
