What is the paint of the roof fire pipe that will fall off quickly, is it a paint quality problem or

I haven't seen this and can't conclude that it's a one-sided reason. 1: Paint quality, poor adhesion; Two:

The adhesion caused by the fire hose not being cleaned thoroughly before painting is not enough; Three: Perhaps in order to save costs, the use of professional paint that is not heat-resistant and light-resistant to fire pipes, so there are also cases of this; Four: the surface of the fire pipe is in contact with corrosive liquids, resulting in paint pulverization.

The problem you are talking about is the quality of the paint, and the main reason is that the adhesion is not enough! Reasons for insufficient adhesion: 1. The surface of the pipe body has not been sandblasted and rust removed, or the rust removal is unqualified, the anchor depth is not enough 2, the adhesion of the paint itself is not strong, the proportion of each component in the formula is not right, and in addition, the paint is not weather-resistant (mainly ultraviolet rays) can also cause it to fall off!

When finishing, there are impurities on the surface, such as rust that is not sanded or not cleaned, which is generally the case. Sun exposure, humid environment and other quality problems mostly occur here!

There is also the possibility that the wrong paint was used.

The surface is poorly cleaned before painting, regardless of the quality of the paint.

The quality of the paint, the spicy heat of the sun. The rain washes away, the air is salty.

The main thing is that the paint quality is too poor.

Try using phosphating primer, epoxy zinc-rich paint as the base, and then make a topcoat, the adhesion will be better.

Master, why don't the pipes on the sky take insulation measures, people with a little common sense should know.

Summary. This is because the surface treatment of the pipe is not done well before the primer is applied. If the surface of the pipe is treated clean before applying the primer, there is no oil, no dust, and no other substances that affect the adhesion of the paint (such as water or other foreign matter left on the surface of the pipe when it leaves the factory).

In this way, after treatment, you can use it for a long time after brushing the anti-rust primer and topcoat. In addition, a pipe surface that is too smooth will also affect the ability of the paint to adhere. The roughness of the pipe surface should be increased to solve the problem.

I think it's useful, give it a thumbs up.

What's the problem.

That's all it said.

The peeling of the paint may affect its service life and safety performance, so it needs to be dealt with in time. Here are some ways to deal with it:

1.Cleaning: The peeling paint surface can be cleaned with clean water or mild detergent to remove loose pigments and dirt.

2.Grinding: For more stubborn areas where the paint is peeling, you can use sandpaper, wire brushes, and other tools to sand and make the surface smooth and flat.

3.Touch-up: Reapply a suitable paint for fire service ducts on a cleaned and sanded surface, taking care to allow enough time to dry between layers.

4.Replacement: If the fire pipe has aged or is seriously damaged, it is recommended to replace the fire pipe with a new one to ensure safety and reliability.

Regardless of the treatment method, it is important to pay attention to the relevant regulations and operating procedures during the construction process, and ensure that the construction quality meets the standard requirements. At the same time, in the daily maintenance and management, we should also strengthen the inspection and maintenance of fire-fighting equipment and facilities, and find problems in time and solve them.
