In the automotive industry, aluminum foil corrugated tubes for automotive heat insulation can be used as copper tubes for protection purposes in shifter cables, speed indicator cables, hydraulic systems, power cables, and liquefied petroleum gas systems. So, what are the factors that affect the performance of automotive heat insulation tubes? We have sorted out this issue and identified several important reasons, summarized as follows.

The presence of oily deposits on the spark plug indicates the entry of lubricating oil, while the cracks on the top of the insulator may be due to the low grade of gasoline. When maintaining a car, more attention should be paid to the condition of the spark plug, as a high-performance spark plug can enhance the vehicle's power performance. Generally, the service life of a spark plug is 15,000 kilometers, and even long-lasting spark plugs do not last longer than 30,000 kilometers. However, many car owners often encounter various problems with their spark plugs, which shorten their normal service life.

What are the basic performance characteristics of sealing?
The basic performance of automotive rubber sealing strips includes controllable sealing performance requirements such as hardness, tensile properties, strength, elongation at break, and compression set. According to industry standards, automotive

parts coating is the pretreatment before painting. The purpose of pretreatment for automotive plastic parts before painting is to improve the adhesion of paint to plastic through a series of physicochemical methods, reduce various defects in the coating, and thereby enhance the quality of the plastic coating. Pretreatment for plastic parts before painting includes conventional treatment, acid treatment, flame treatment, surfactant treatment, hot solvent treatment, ultraviolet treatment, and plasma treatment.
