What should be paid attention to when producing Automotive Wiring Harness Protection Sleeve in summer and winter

The biggest difference between summer and winter is the temperature and the formula of Automotive Wiring Harness Protection Sleeve products. Due to the seasonal ambient temperature, the formulas of summer and winter are generally different. Braiding sleeves for car harness protectors is a very important process. Temperature has a certain influence on Braided Sleeve. Therefore, when producing Automotive Wiring Harness Protection Sleeve in summer and winter, we must pay attention to the temperature and the formula of Automotive Wiring Harness Protection Sleeve products.

First of all, when producing Automotive Wiring Harness Protection Sleeve, more vulcanizing agents and softeners are generally added to the formula in winter. The amount of plasticizer in the formula in winter should be increased by 5 parts compared with that in summer, and the temperature and time of rubber drying in winter should be increased. Changes in the ambient temperature in summer and winter will affect the vulcanization rate and also affect the workability. The hardness of vulcanized rubber in winter is significantly improved, and the scorch time is significantly increased. Therefore, in winter, the sulfur starting point is generally adjusted a little faster, and more plasticizers are added, while the opposite is true in summer.
Secondly, there is a difference between summer and winter and the vulcanization system in the formula. In the south, it is particularly obvious that the vulcanization speed is fast and the production capacity is high. The difference between the formula in summer and winter is quite large. Lower the vulcanization system and increase the scorch time, but if it is winter, you can speed up the vulcanization system of the formula, so in the production process, if the vulcanization speed in summer is still the same as in winter, then there will be Bulk knitting sleeve scorch, while winter is fine! If the sulfur rate of the formula Braided Sleeve is suitable in summer, then the amount of accelerator should be appropriately increased in winter; on the contrary, if the formula Braided Sleeve has a suitable sulfur rate in winter, the storage period of the Braided Sleeve in summer will be significantly shortened, so the anti-scorch agent can be added to prolong the scorch time.
Finally, manufacturers of Automotive Wiring Harness Protection Sleeve remind that the difference between winter and summer lies in the change of ambient temperature. Therefore, the mixing time can be extended appropriately during mixing, and the temperature of cooling water can also be increased.
