The main use of color coated steel plate is outdoor buildings, and as a building raw material product, it also has its service life. The length of service life largely depends on the nature of surface coating and the impact of service environment.

The nature of the coating generally refers to the coating system adopted, whether it is ordinary polyester, high weather resistant polyester, silicon modified polyester or PVDF coating. Different coatings will naturally bring different life effects.

As for the use environment, we should consider whether it is an ordinary use environment, or in a heavily corrosive environment, or in areas with particularly strong ultraviolet rays, tropical areas with particularly large precipitation, etc. the same color coated board will naturally show different service life in different environments.

In the process of studying the service life of the color coated board, Huijin Technology Center found that in addition to the two conditions mentioned above, in fact, the dust in the environment also has a great impact on the service life of the color coated board. The main action mechanism is: the dust is deposited on the surface of the color coated board, meets rain or dew, changes the pH value of the water, and then forms micro corrosion to the coating, and finally destroys the coating; Or when the coating is heated and softened by sunlight, dust particles take the opportunity to embed into the coating to form micro voids, which gradually destroys the surface of the coating and affects the service life of the color coated plate.

Therefore, generally large-scale buildings will regularly clean the surface of the color coated plate, not only for beauty, but to ensure that the service life of the color coated plate will not be affected. So is there a way to make the color coating board not accumulate dust, or let the color coating board have its own function of cleaning itself?

First, what type of coating has self-cleaning effect: the research shows that there are two directions to choose: one is to take the hydrophobic route to make the coating have hydrophobic effect and lotus leaf effect; Second, take the hydrophilic route to make the coating have hydrophilic effect; So we made actual models and buildings. After two years of outdoor observation, we found that the hydrophobic effect is very unsatisfactory, or not only does not have the self-cleaning effect, but plays a negative role. The color coated board with hydrophobic route accumulates more dust on the surface and is more difficult to clean! The hydrophilic road line shows excellent self-cleaning effect, and the surface of construction products is as new as before!

Then there are two options for hydrophilic route: one is to adopt two-component two-coating self-cleaning coating system; Second, choose a single component three coating self-cleaning coating system. Which effect is more obvious between the two? The experimental results show that the coating system with three coatings and one component has more obvious effect and longer retention time!

Huijin's high-cleaning board precisely adopts the three coating single component self-cleaning coating system. At present, there are only two enterprises in the world, one is bosg and the other is Huijin!

Now let's take a look at how Huijin's three coating self-cleaning technology makes the color coated board more excellent and outstanding!

I Self cleaning mechanism of Huijin high cleaning board:

Huijin high cleaning plate is a kind of inorganic hydrophilic coated color steel plate with high self-cleaning performance; On the basis of traditional color steel plate, an inorganic hydrophilic coating is added through three coating and three drying process. For buildings with high-cleaning boards, when it rains, the whole building is like taking a bath, which can easily wash away the dust particles and pollutants attached to the building board, so as to be highly self-cleaning;

I believe you have basically understood the technical mechanism, detection method and application effect of Huijin Gaojie board So what benefits can Huijin Gaojie board bring to you?

I Cost savings

When reviewing the warranty period of color coated board buildings, many end customers will find that there is a provision that different areas of buildings need to be cleaned several times a year, and the most critical areas even need to be cleaned once a month. This is a huge expense for end customers, but if they are not cleaned, the service life of color coated board on the outer layer of buildings cannot be guaranteed. However, if Huijin's high-cleaning board is adopted, the cleaning times can be greatly reduced, It doesn't even need cleaning, which is undoubtedly very attractive to end customers in terms of cost!

II Wider choice

Many customers may have a question: can gaojieban choose ordinary polyester, high weather resistant polyester, silicon modified polyester and PVDF? The answer is: Yes! The high-cleaning board developed by Huijin technology center has a wide range of applications. The top inorganic hydrophilic coating can be coated on various types of coatings to give self-cleaning effect without affecting any performance and quality assurance conditions of the original coating

So what are the disadvantages or limitations of Huijin Gaojie board?

The answer is: Yes! At present, in some special appearance, either the two-component two-layer hydrophilic coating or the three layer hydrophilic coating of Huijin Company can not be reflected in these products, such as sand coating, wrinkle coating, aluminum powder coating, hammer coating, etc

Although there are restrictions on the use of Huijin high-grade cleaning board due to its special appearance at present, its shortcomings do not hide the shortcomings. Huijin high-grade cleaning board can be used and reflected in the most common and widely used product types It can not only improve the quality, expand the performance and save the cost to the majority of users, but also bring us more business opportunities!
