How many years of anti rust with alkyd paint for steel structures

You belong to the last part of the paint, steel structure alkyd paint, he is divided into 3 parts, 1, alkyd anti-rust paint, 2, alkyd paint thinner, 3, alkyd magnetic paint, the comprehensive unit price is 450 yuan

According to the anti-rust years: 1Anti-rust life 1 2 years, choose alkyd paint. Alkyd paint is the best choice for civil paint, alkyd paint has bright colors, and is suitable for painting doors and households at home.

The outer railing is rust-proof. **Low, colorful, convenient and simple construction. 2.Anti-rust life 5 8 years, choose acrylic polyurethane oil.

Lacquer. Acrylic polyurethane paint is a hot selling paint. The anti-rust life is moderate, which eliminates the trouble of re-construction of alkyd paint in 1-2 years.

**Moderate, beautiful surface of the paint film. 3.Anti-rust life 10-15 years, choose fluorocarbon paint.

The most desirable should be to spray fluorocarbon paint! Steel structures are easy to rust in some specific environments, especially in the environment with corrosive media, and must be painted or galvanized, and should also be regularly maintained during use. If it is a large steel structure, it is more troublesome to galvanize the large steel structure support.

Therefore, most people will choose to spray paint to achieve the function of rust prevention. When choosing paint, it is also a science, if the choice of paint is improper, it may lead to chalking, peeling, and falling off after spraying paint. So how do you choose a paint?

There are three types of paints that can be used outdoors, and most of the fluorocarbon paints are used for exterior wall defense.

Rusty, large and beautiful steel structure frame. The self-cleaning function of fluorocarbon paint makes its surface more beautiful and bright, and the anti-rust life is all paints.

One of the longest in the world. Therefore, many buildings that are afraid of repeated construction and pursue aesthetics choose fluorocarbon paint.

Summary. The specific anti-rust period is judged according to the type of paint, the use environment, and the supporting paint. Ordinary anticorrosive paints use red dan antirust paint, iron red antirust paint, alkyd paint and other anti-corrosion years are about 3-5 years.

Heavy anticorrosive paints epoxy zinc-rich primer, epoxy micaceous iron intermediate paint, and fluorocarbon paint can be theoretically up to 20 years. If the topcoat uses chlorinated rubber, acrylic polyurethane paint, etc., it can reach about 10 years. It depends on what kind of environment and what kind of supporting scheme.

Hello, I have a basic understanding of your question, and I am working hard to sort out the answer for you! Please wait a moment!

The specific anti-rust period is judged according to the type of paint, the use environment, and the supporting paint. Ordinary anticorrosive paints use red dan antirust paint, iron red antirust paint, alkyd paint and other anti-corrosion years are about 3-5 years. Heavy anticorrosive paints epoxy zinc-rich primer, epoxy micaceous iron intermediate paint, and fluorocarbon paint can be theoretically up to 20 years.

If the topcoat uses chlorinated rubber, acrylic polyurethane paint, etc., it can reach about 10 years. It depends on what kind of environment and what kind of supporting scheme.

The service life of the anti-corrosion layer is different due to the different reasons of the selected anti-corrosion materials, construction technology, and use area.

For example, the steel structure ordinary grade coating anti-corrosion, the use of epoxy iron red primer, epoxy micaceous iron middle layer paint chlorinated rubber topcoat to form a composite coating, the expected service life of 10 years.

Alkyd paint and zinc ash undergo saponification reaction. - So alkyd paint is not allowed to be applied to the surface of the galvanized layer. Not only will the paint come off, but it will also consume the zinc of the galvanized layer.

Galvanized steel is mostly smooth, and the adhesion of ordinary paint is insufficient. So the vast majority of lacquers do not adhere well.

The available paints for galvanized steel include phosphating primer, cold galvanized paint, epoxy zinc yellow primer and other types.

Colorful paint is at your service.

The surface is smooth and cannot be adhered to, so it is recommended to use a special primer for crown galvanized parts.

Project Index The color and appearance of the paint film conform to the model, the paint film is flat, and the number of brush marks is allowed. (Tu-4 viscometer) S mu head Hardness (double pendulum) Adhesion grade 2 Flexibility mm 3 Water resistance (immersion 6h) Allow slight devastation and color recovery after 3h.

1. Air spraying and brushing are acceptable.

2. The substrate should be cleaned before use, free of oil, dust, rust, etc.

3. The viscosity can be adjusted with X-6 alkyd diluent.

4. When spraying the topcoat, if the gloss is too high, it must be sanded evenly with 120 mesh sandpaper or constructed before drying after the surface of the previous paint is dry.

5. Hongdan anti-rust paint cannot be directly used on zinc and aluminum substrates, and has poor weather resistance when used alone, so it should be used in conjunction with topcoat.
