How many years can the color steel tile last after renovation?

In the absence of corrosives, remove man-made damage factors, and the product quality is goodColor steel tileThe service life of rust removal and refurbishment can reach about 20 years.

It is inseparable from various factors such as the service life of its own color steel tile and the anti-corrosion life of the special paint for the renovation of the selected color steel tile.

Color steel tile rust removal and renovation steps:

Special equipment is used for grinding and rust removal or sandblasting and rust removal, and there shall be no rust spots in the base layer after rust removal, oil, grease, dust, iron sand and metal oxides.

and so on to clean up.

Before the spraying process, in case of rain or other conditions that cause the surface of the matrix steel to be wet, it is necessary to wait for the environment to reach the construction conditions, and then remove the rust after drying the surface moisture with dry compressed air;

The surface of the steel after rust removal reaches the derusting grade, and the surface is cleaned before the next process can be carried out, and the surface of the steel after the rust removal is qualified shows a metallic luster.

If the rust has been returned before the primer, re-polishing and rust removal or sandblasting rust removal, do not reduce the abrasive requirements to avoid reducing the roughness.

Four or five years to do a few projects is not very good, if it is a large area of corrosion, it will be three or four years. If there is local corrosion in a small area, it is not a big problem in seven or eight years.

rust removal and grinding; Spray paint; After construction, the color steel plate can be used for more than 8 years.

Color steel tile renovation 8 20 yuan a square meter or so.

The ** of color steel tile renovation painting construction is generally 8 20 yuan per square meter. The use of paint, color steel tile renovation spray paint** is mainly based on the degree of corrosion of color steel tile and the number of spraying. For example, some customer plant color steel tile rust is very serious, some are only slight corrosion, some have water leakage, and some only need to do paint spraying, so in this case, it is difficult to have a standard, all need to be based on customer requirements and the actual situation of the site, according to the development of the color steel tile renovation construction plan to carry out, but generally ** are in 8 20 yuan per square meter.

The specific color steel tile renovation process is as follows:

1. If the color steel tile is exposed to the outdoors for a long time, in addition to rust spots, there will be impurities such as old patent leather, dust, mud, and oil stains on the surface. In order to get better construction results and prolong the service life of color steel tiles, rust removal should be carried out before construction, and professional rust removal equipment such as grinding machines can be used to achieve the standard of rust removal grade.

2. High-pressure cleaning equipment can be used to clean the color steel tile after rust removal. Clean the dust on the color steel tile, so as not to block the combination of the primer and the metal surface of the color steel tile when spraying the special primer, which will affect the construction effect.

At the same time, when cleaning, pay attention to the uneven or cracked surface of the color steel tile, and then carry out construction after reinforcement to ensure the firmness of the color steel tile roof.

3. Confirm that there are no impurities such as rust, moisture, dust and other impurities on the base surface of the color steel tile before construction. The color steel tile is stirred evenly with the new special primer containing the key, and the high-pressure spraying machine can be used for construction, and the spraying process should be guaranteed to be uniform, no accumulation, and no omission.

4. After waiting for the primer to dry, carefully check the corners, side seams, lap joints and other places that cannot be sprayed in place at one time, and repair the paint to ensure that there is no omission.

5. After the touch-up paint is completed, wait for the primer to dry before spraying the topcoat. Make sure the primer surface is clean and tidy before spraying, so that the primer and topcoat can be easily combined. The topcoat and primer are sprayed in the same way, using a high-pressure spraying machine to ensure uniformity, no accumulation, and no omissions during the spraying process.

For parts that cannot be sprayed in place at one time, touch-up paint should be carried out. <>

In the process of using color steel tile, there will be local rapid rust in about six years, corrosion, fading, once it appears, it is extremely fast to be rusted, and only by spraying anti-rust and anti-corrosion paint can its life be extended. As a new type of product, the stainless steel foil waterproof roll can make its annual eggplant limit reach 20 years, which greatly reduces the number of replacements and the cost of use.

The stainless steel foil waterproof roll is made of 304 pure stainless steel as the base material, which has super corrosion resistance, wear resistance, high temperature resistance, strong waterproof performance and easy surface cleaning. At the same time, it is "tear-and-use, time-saving, labor-saving, and long-term", so it is a new product with extremely good performance and stable quality on the market.

Good materials can be used for ten years, there will be fading but will not rust back to rust, chalking, peeling, peeling, etc., does not affect the basic use.

National orders, professional construction, only the use of market-tested big brand materials, each batch can be scrambling file for quality inspection reports and certificates, quality assurance.

Hello! It's not very good to do a few projects in four or five years, and if the socks are corroded, it's three or four years. If there is local corrosion in a small area, it is not a big problem in seven or eight years.

When in doubt, please ask.

The construction process of color steel tile renovation is as follows:1. The roof needs to be cleaned and cleaned, and all the roof is polished and rusted. After rust removal, there shall be no rust spots in the base layer, and oil, grease, dust, iron sand and metal oxides shall be cleaned up.

When the roof reinforcement is not loose, no rust, no dust, and no open water, do the following anti-corrosion renovation.

2. Stir and shake the anticorrosive coating before use to ensure that the product effect reaches the state.

3. The whole epoxy primer is sprayed once, and then the acrylic polyurethane paint topcoat is sprayed after 12 hours of drying.

Technical measures for the renovation of color steel tiles1. The construction temperature should be 5 degrees to 35 degrees, and the relative humidity should be 85%, which should not be applied under the conditions of rain, fog, snow and large dust.

2. After the color steel tile is polished clean, the leakage is found in the local area. Patch with metalworking glue.

3. Ensure that the coating is completely evenly covered during construction, and if there is a missing or weak coating, it needs to be repaired in time.

4. For heavy anti-corrosion construction, it is recommended to paint it again after 12 hours.

Color steel tile spray paint renovation can use paint with strong weather resistance.

Because the color steel tile needs to be exposed to the air for a long time, the paint with strong weather resistance should be selected during renovation to ensure that there is no cracking and fading under the irradiation of the sun and rain. It is recommended to brush SD-CW308 primer once first, which is conducive to improving the basic adhesion and making the topcoat more saturated. Then apply two layers of paint to maximize the effect of the paint and extend the service life.

If the color steel tile comes into contact with acid, alkali, etc., it will produce chemical reactions and produce rust, and it is very likely that there will be serious rust and perforation after a long time. If it is not redone in time, it will make the color steel plate rust more serious, and when it is serious, not only can it be solved by renovation, but also the entire roof waterproofing measures must be redone, which will cost more.

Before renovating the color steel tile, you must first clean up the dust and debris on the surface of the color steel tile, then use a wire brush, abrasive cloth, etc. to polish the rust on the surface of the color steel tile, and then use a clean rag to clean up the floating dust on the surface of the color steel tile, and then start painting construction.

Under normal circumstances, when renovating the color steel tile, it is best to carry out two times of topcoat spraying construction, and the primer of the color steel tile should be covered when spraying the topcoat. If the primer can still be seen after the topcoat has been sprayed, then it means that the topcoat has been sprayed too thinly.

The color of the newly installed color steel tile is bright, and because the construction is simple and reasonable, it is used by many enterprise plants, although there are many advantages, but in the end it is impossible to escape the result of rust. And the longer the color steel tile is used, the more serious the corrosion, so it is necessary to do the renovation of the rusty color steel tile.

1. Why do color steel tiles rust?

The corrosion process of color steel tile roof is a complex chemical reaction process. We will find that rust is usually brown and reddish in color and is mainly composed of hydrate of iron oxide and iron hydroxide. The rust on the surface of the color steel tile seems to be attached to the substrate, but in fact, it is not firmly attached to the substrate, or there are small holes in the middle, and the oxygen and water vapor in the air are in direct contact with the substrate through the holes, which eventually leads to the rust of the substrate of the color steel tile.

We know that the color steel tile has been in the wind and sun for a long time, and after the surface paint layer is aged, there will be the oxygen in the air in direct contact with the substrate, resulting in rust, so the renovation and anti-corrosion construction is actually to isolate the substrate from the air through the paint and the direct foundation, so that the substrate is in a completely sealed environment, so that it can not react with the oxygen in the air, to achieve the purpose of anti-corrosion and anti-rust.

2. What are the benefits of color steel tile renovation?

Therefore, some customers will have concerns when choosing renovation, thinking that the color steel tile has rusted, even if the renovation is only surface work, and can not extend the service life of the color steel tile, this idea is wrong, we only need to understand the cause of the rust of the color steel tile can know that through the renovation can actually achieve a good anti-corrosion effect.

1. It does not affect the normal production plan of the enterprise;

2. Anti-ultraviolet rays, superior anti-aging performance;

3. Strong acid and alkali resistance;

4. It can effectively prevent the roof from further aging and rusting;

5. The coating is tough, good adhesion, breathable, and the system does not crack, bulge, or peel;

6. The cost of renovating the roof is low, the construction period is short, and the service life is as long as 8-10 years.

The main reason is that the original fireproof paint is aging, which cannot prevent the color steel tile from rusting, so it must be repainted.

a, color steel tile long-term exposure to a variety of harsh climatic conditions, due to the color steel plate contains iron, contact with acid, alkali and organic solvents will produce chemical reaction to generate iron dioxide, that is, rust, to make the color steel plate rust serious when there will be corrosion rust holes. If you do not do anti-corrosion renovation in time, it will slowly make the color steel plate rust more and more serious, and then the maintenance is not only anti-corrosion renovation, but also waterproof and anti-corrosion of the entire roof, which greatly shortens the service life of the color steel tile construction, and even replaces the color steel tile as a whole, which increases the cost of material demand.

B, the color steel tile corrosion is serious and there will be rust holes, in the rainy weather there will be a problem of rain leakage, which brings a lot of inconvenience to our factory production, if it is the factory warehouse roof color steel tile leakage problem, resulting in our goods soaked in rainwater for a long time, directly causing the goods to rot and deteriorate, will bring us huge losses! Whether it is a factory or a plant, the color steel tile has not been renovated and repaired in time, and in serious cases, it may bring a series of safety hazards such as the color steel tile building falling off. Thus bringing greater economic losses.

We should be cautious about the renovation and repair of color steel tiles, especially for the renovation and repair of color steel tiles in large industrial plants, and we cannot go to construction casually. Not only the special paint for the renovation of color steel tiles should be selected appropriately, but also the construction operation should be carried out according to the standard process of color steel tile repair. Today we will talk about what misunderstandings should be avoided in the renovation construction of color steel tiles.

Myth 1: Use the most inexpensive and rust-proof and weather-resistant color steel tile renovation special paint. We strongly appeal here not to draw a temporary **low, if you buy the paint although **is half of the normal**, but use it to do color steel tile renovation and repair less than 2 years or so began to appear peeling, cracking, fading and a series of problems, but the loss is greater.

Leave it alone, then the color steel tile will continue to corrode, the original spray paint can not play any role in rust prevention, if the reconstruction, but also to spend a lot of material costs and labor costs, if you still use the most cheap, performance of unknown material construction, then the next problem is not far away. Such repeated construction is really time-consuming, labor-intensive, and costly. Therefore, it is better to do a good job in the renovation and anti-corrosion project of color steel tiles at one time, at least for more than 5 years, so that it is cost-effective and cost-effective.

Myth 2: In order to save costs, spray topcoat directly instead of primer. The role of the primer is to prevent rust and better combine the topcoat with the color steel tile substrate, and the role of the topcoat is to prevent corrosion and enhance the aesthetics and fullness.

It can be seen that if the primer is not sprayed, the surface is easy to return to rust, and the corrosion will become more and more serious if there is more rust. Therefore, when we do renovation anticorrosive painting, we should not only pay attention to "face", but also pay attention to "connotation". Today we will talk about two misunderstandings first, and tomorrow we will talk about what other misunderstandings to avoid.

Myth 3: In order to speed up the renovation construction progress of color steel tiles, spray rust fixing agents on the surface of rusty color steel tiles without grinding and treating rust. The rust fixing agent does not remove the rust on the surface, but forms a transparent layer of grass on the surface, sealing the iron on one side.

The surface is not flat, which will affect the sealing of the spray paint, which will affect the fastness of the special paint for the renovation of color steel tiles, which is easier to peel, and there is also a fact that the iron inside is not really removed, temporarily closed inside, so that it is easy to continue to corrode the board surface, and does not play a role in anti-corrosion, just a psychological comfort.

Myth 4: The previous coating has not been done yet, but the surface is dry and can't wait to spray the next coating. This can easily lead to peeling, which is the conclusion reached by Siding technicians based on theory and repeated test experiments, if you are doing color steel tile renovation construction projects, this is worth learning from In short, color steel tile renovation construction can also be said to be a project, especially for a large area of plant metal roof renovation.

Try to use high-quality color steel tile renovation paint during construction, and can not be sloppy in construction.
