The Universiade Lecture Hall tells you those things about automobile rubber

Mar 31, 2022

First of all, I would like to ask everyone, do you know why the rubber water pipes and trachea seen at home or on the roadside have cracks for a long time? What factors cause the cracks of rubber parts, and what methods are used to detect the rubber pipes on the car to ensure that its service life.

The following editor will take you to understand the truth of rubber cracks. It is ozone. The content of ozone in the atmosphere is very small but it is the main factor for rubber cracks. The Dayun Testing Center has a mature ozone aging detection system, which can simulate and strengthen the atmosphere. Rapid identification and evaluation of rubber resistance to ozone aging under ozone conditions.

For vulcanized rubber such as brake hoses, water hoses, vulcanized rubber materials, wiper strips and other vulcanized rubbers used in vehicles, if the ozone resistance is not up to standard, cracks in the rubber parts will occur under certain pressure, resulting in leakage of brake pipes and water pipes. The reason is that ozone easily reacts with unsaturated bonds in rubber, resulting in rubber degradation. Improper selection of brake hose materials or problems in the production process will affect the ozone resistance of the outer rubber layer, resulting in leakage, resulting in brake failure.

The leakage of automobile hoses during use is mostly caused by the poor ozone resistance and durability of the outer rubber layer of the brake hose. First, remove the sheath of the automobile brake hose, and then bundle the brake hose assembly 360° around the mandrel. In the ozone aging test box at ℃, keep it for 70±2h and observe whether there are cracks on the outer surface with a 7 times magnifying glass. Through the ozone detection test, possible risks are avoided, and the quality of Dayun vehicles is controlled.

The Dayun Automobile Testing Center has a complete testing system and advanced testing equipment, strictly controls the quality, ensures the product quality of Dayun automobiles, and carefully casts the Dayun brand.
