1、脱层,橡胶之间发生了周向裂口或着是分层。
1. Delamination, circumferential cracks or delamination between rubbers.
造成脱层的原因:
Causes of delamination:
(1)胶料中可能含有水分户或者是其他杂物,尤其是纤维胶在储运的过程中被雨水、杂物污染。
(1) The rubber may contain water or other sundries, especially the fiber rubber is polluted by rainwater and sundries during storage and transportation.
(2)胎胚保温不良、硫化机的温度波动造成了欠硫。
(2) Poor heat preservation of embryo and temperature fluctuation of vulcanizer caused sulfur deficiency.
(3)胎胚成型太早而且停放时间太长,造成了胎胚胶料的自硫。
(3) The formation of the embryo is too early and the storage time is too long, resulting in the self sulfur of the rubber in the center of the embryo.
(4)使用时超载、超速运行。
(4) Overload and overspeed operation during use.
2、自动上料搅拌车脱圈,发生脱圈的原因:
2. The automatic feeding mixer is out of loop, and the reasons for the out of loop are as follows:
(1)粘合剂粘度没有达到工艺要求。
(1) The adhesive viscosity does not meet the process requirements.
(2)涂粘合剂之后表面受到了污染。
(2) The surface was contaminated after the adhesive was applied.
(3)自动上料搅拌车胎胚保温不良、硫化机的温度有波动造成了欠硫。
(3) The poor heat preservation of tire embryo of automatic feeding mixer and the temperature fluctuation of vulcanizer caused sulfur deficiency.
(4)使用时超载、超速运行。
(4) Overload and overspeed operation during use.
3、自动上料搅拌车掉块:就是指橡胶表面局部块状脱落
3. Block falling of automatic feeding mixer: refers to local block falling off of rubber surface
发生掉块的原因:
Reasons for block falling:
(1)硫化时间到后没及时开模,造成过硫、老化。
(1) The mold was not opened in time after the vulcanization time, resulting in over sulfur and aging.
(2)胶料混炼、热炼不均匀。
(2) Uneven rubber mixing and heat mixing.
(3)胎胚保温不良、硫化机温度波动造成欠硫。
(3) Insufficient sulfur is caused by poor heat preservation of embryo and temperature fluctuation of vulcanizer.
(4)使用环境比较差,所以被外力割伤。
(4) The service environment is poor, so I was cut by external force.
(5)使用环境中含有化学物品腐蚀。
(5) The service environment contains chemical corrosion.
4、自动上料搅拌车径向裂口:橡胶沿直径方向裂口,多发于白色压配式
4. Radial crack of automatic feeding mixer: the rubber cracks along the diameter direction, mostly in the white press fit type
发生径向裂口的原因:
Causes of radial cracks:
(1)胶料扯断强度、耐老化性能不够。
(1) The breaking strength and aging resistance of the compound are not enough.
(2)硫化时间到后没及时开模造成过硫、老化。
(2) The mold is not opened in time after the vulcanization time, resulting in over sulfur and aging.
(3)自动上料搅拌车超载。
(3) The automatic loading mixer truck is overloaded.
