Motorcycle exhaust pipe is one of the most important motorcycle parts. Anti-corrosion and anti-rust is a difficult problem for vehicle coating. Some people think that the rust of automobile and motorcycle exhaust pipe is because ordinary paint is not resistant to high temperature, so use high temperature anti-rust paint , How is the effect?

 

How high is the exhaust pipe of a motorcycle?

 

The temperature of the exhaust pipe of a motorcycle varies from 300 degrees to 80 degrees when driving on the road. The closer to the engine, the higher the temperature. In extreme cases, such as when the speed exceeds 5500 rpm, the temperature of the motorcycle exhaust pipe near the engine can reach 700 degrees.

 

Why do motorcycle exhaust pipes rust?

 

The rust of the exhaust pipe of a motorcycle is not due to high temperature. It is because the steel gradually loses its protective coating and rusts in the process of alternating heat and cold. To put it simply, the original protective coating was lost due to high temperature or alternating heat and cold, and rust occurred at normal temperature.

 

Why is it not recommended to use ordinary high temperature anti-rust paint on motorcycle exhaust pipes?

Ordinary high temperature resistant paint will lose its anti-rust effect or mechanical properties after alternating cold and heat. Most high-temperature and anti-rust paints are designed for long-term high-temperature operation with infrequent temperature changes. It can't adapt to the working condition that motorcycle exhaust pipe often alternates between cold and heat, which is susceptible to impact.

 

 

Does the motorcycle exhaust pipe use high-temperature paint?

 

If you want to paint the motorcycle exhaust pipe without losing paint, you must choose a special paint for motorcycle exhaust pipe. The special paint for motorcycle exhaust pipe is a heat-resistant paint for motorcycle exhaust pipe system and muffler parts. It is suitable for motorcycles. , Motorcycle exhaust pipe and muffler protection for agricultural machinery. Has very good heat resistance, mechanical properties and salt spray resistance.

1. The special paint for motorcycle exhaust pipe is suitable for painting workpieces below 650 ℃. After 24 hours in 600 ℃ environment, the paint film will not blister or fall off. It can adopt electrostatic spraying and manual spraying processes, the coating film is smooth, and the protection of the workpiece is excellent.

 

2. Special paint for motorcycle exhaust pipe has excellent salt spray resistance. After baking in a 210 ° C environment for 40 minutes, the sample is naturally cooled down, and the salt spray test is carried out for 60 hours, and the paint film is free of blistering and rust. After baking for 24 hours in a 650 ° C environment, the sample was naturally cooled down, and the salt spray test was conducted for 120 hours. The paint film did not blister or rust.

 

3. The special paint coating for motorcycle exhaust pipe can withstand 6 cycles of hot and cold, and the paint film is intact. This test refers to the index for evaluating the anti-breakage ability of the paint film when it undergoes rapid temperature changes. Put the high temperature resistant paint sample in the oven to heat up to hundreds of degrees Celsius, and then put it in room temperature water for one cycle. After 6 tests, observe the state of the paint film.
