整体喷涂功能性阻锈底漆

After the color steel plate is polished and rinsed and the roof is dry, spray the functional rust-inhibiting primer on the whole roof. After spraying the paint on the more rusty steel surface for 1-3 minutes, all the rust layers will disappear and the surface of the workpiece will appear blue. The black protective film can achieve long-term anti-rust effect. This coating can be used with any oily topcoat. At the same time, it also has the effect of linking up and down, which can isolate the color steel plate from contact with the air and moisture in the air, avoid second-degree rust and avoid rust back.

There are certain pollutant gases in the production process of nearby factories, as well as acid and alkali gases in the air. Long-term exposure to such an environment has led to large areas of corrosion of the color steel roof. This workshop is a die-casting workshop. The gas in the production process will cause oxidation and corrosion of the color steel plate. In addition, the local rainfall and climate have a certain impact on the roof rust, and the roof has different degrees of rust. Whenever it rains, the rust on the roof is affected by the environment and oxidized and decomposed by acid-base rainwater. The rainwater will flow downstream along the color steel plate, resulting in serious rust marks. After a long time, a large area of rust has been present.

After the reinforced epoxy mica iron red intermediate paint is dry, spray acrylic anticorrosive topcoat on the whole roof. It dries fast, the paint film has high hardness, chemical resistance, solvent resistance, It has excellent scratch resistance, heat and humidity resistance, which can isolate ultraviolet rays, heat dissipation, protect the entire anti-corrosion system, extend the service life of the coating, and enhance the anti-corrosion effect. The color of the topcoat is normally white, and the current color is close to the original color steel plate and the color is dark blue.

防腐完工后

The whole roof is polished and rusted, rinsed, and the whole roof is sprayed with anti-corrosion materials three times to make the roof look new, and the color is dark blue.

There are certain pollutant gases and acid and alkaline gases in the air in the production process of nearby factories. Long-term exposure to such an environment has caused large-scale corrosion of the color steel roof. This workshop is a die-casting workshop. The gas in the production process will cause oxidation and corrosion of the color steel plate. In addition, the local rainfall and climate have a certain impact on the roof rust, and the roof has different degrees of rust. Whenever it rains, the rust on the roof is affected by the environment and oxidized and decomposed by acid-base rainwater. The rainwater will flow downstream along the color steel plate, resulting in serious rust marks. After a long time, a large area of rust has been present.

After the functional rust-inhibiting primer dries, spray the reinforced epoxy mica iron red intermediate paint on the entire roof. This function is: shielding, electrochemical protection, self-repairing and passivation of the coating film, when there is chemical corrosion Under the conditions, the coating is the anode and the metal is the cathode without being corroded. This is the basis for the design of the cathodic protective coating. Mica iron red protects the color steel plate from chemical corrosion very well.

There are certain pollutants in the production process of nearby factories, as well as acid and alkaline gases in the air. Long-term exposure to such an environment has led to the appearance of large-scale color steel roofs. Corrosion phenomenon. This workshop is a die-casting workshop. The gas in the production process will cause oxidation and corrosion of the color steel plate. In addition, the local rainfall and climate have a certain impact on the roof rust, and the roof has different degrees of rust. Whenever it rains, the rust on the roof is affected by the environment and oxidized and decomposed by acid-base rainwater. The rainwater will flow downstream along the color steel plate, resulting in serious rust marks. After a long time, a large area of rust has been present.

Project introduction

The roof is a double-layer sandwich panel, and the color steel roof has been used for more than 8 years. Due to the existence of certain polluting gases in the production process of the nearby factory and the acid and alkaline gas in the air, it has been in such an environment for a long time. This has led to the appearance of corrosion on a large area of the color steel roof. This workshop is a die-casting workshop. The gas in the production process has certain factors that cause the color steel plate to oxidize and corrode.

In addition, the local rain and climate have a certain impact on the roof rust, and the roof has different degrees of rust. When it rains, the rust on the roof is affected by the environment and the oxidation and decomposition of acid and alkali rainwater. The rainwater will flow along the color steel plate, and the traces of rust are serious. Over time, there has been a large area of rust.

Taking the opportunity of public listing of stocks as an opportunity, customers further regulated the corporate governance structure of the company, established a modern enterprise management system, and realized the overall optimization of enterprise management; by tracking advanced technologies and processes in the international die casting industry, the company improved precision aluminum and magnesium alloy die casting The development and design, manufacturing and information management capabilities of parts and products, expand market share; through adjustment of product structure, the development of diversified, serialized, high-tech and high value-added die-casting products and other measures to enhance the core competitiveness of enterprises . In order to consolidate the company's leading position in China's die-casting industry, and gradually enter the international market, and strive to develop the company into a combination of aluminum alloy, magnesium alloy precision die-casting product research and development, manufacturing, and product sales through 3 to 5 years of efforts. A large-scale professional die casting manufacturer with international competitiveness.

client feedback

Our company has always implemented the business philosophy of being a "first-class enterprise in Hongtu people's mind", not only has strict requirements for product quality, but also maintains stringent requirements for suppliers and engineering quality. For the rust situation, our company has strict requirements for aesthetics. When looking at the office building, the roof is affected by rust stains, and there are many hidden dangers for the production of our company after a long time. Gu Company carried out anti-corrosion renovation project for Hongtu Roofing, with an area of 20,000 square meters. In the overall construction process, the deployment of material personnel for the construction details was reasonable and efficient, and the use condition was good after construction. In the end, our company accepted Yougu as a qualified supplier of our company, and we carried out repair services for our company one after another.
