How to paint antirust paint antirust paint construction preparation and construction work

We all know that a lot of metal exposed to the air will be very easy to rust, mainly because of the reaction with some components in the air, especially the reaction of water and oxygen is the most, so a lot of metal we will isolate the oxygen treatment. The usual practice is to paint, then, how to brush antirust paint? What is the preparation and construction process of antirust paint? Now I can not give you a detailed introduction to how to brush antirust paint and antirust paint construction preparation and construction process.

How to brush antirust paint

The use of antirust paint:

1, can be used by the brush, spraying method of construction, painting should be stirred before painting, if the viscosity of the high, can be added to the appropriate amount of water, the amount of water should not be more than 10%, should be added to stir, to ensure the uniformity of the paint. Ensure that the paint is uniform.

2, before painting the surface of the workpiece gray sand, weld slag, oil, floating rust and old paint skin clean.

3, the construction of ventilation, not in the ambient temperature below 5 ℃ or humidity greater than 70% of the construction conditions.

4, the paint film can be self-drying, can also be low-temperature drying, self-drying temperature of not less than 5 ℃, humidity is not greater than 70%; drying, leveling time of not less than 15 minutes, baking temperature of not less than 60 ℃, baking time of not less than 25 minutes.

5, paint the second time, the first time should be dry, two times at least 24 hours interval.

6, strictly prohibit mixing with other paints and organic solvents.

7, the end of construction, the apparatus used should be immediately rinsed with water to prevent drying. The remaining paint should be kept closed, if there is a dry skin affect the use, can be filtered with 100 mesh screen before use.

Construction preparation and construction process of antirust paint

Construction preparation

Materials

The selection of anticorrosive materials for steel structure project should be in accordance with the requirements of the owner. Anti-corrosion materials include primer, top coat and thinner.

Main machines and tools

Sandblasting gun, air pump, recycling device, paint spray gun, air jet pump, hose, spatula, hand grinding wheel, emery cloth, steel wire brush, cotton wool, small compressor, small bucket of paint, brushes, pickling tanks and so on.

Operating conditions

1, the construction of painters should be special work operation license.

2. The steel structure project has been inspected and accepted before antirust painting project and meets the design requirements.

3. The antirust painting site should be protected by safety measures, fire prevention and ventilation measures to prevent fire and personnel poisoning.

4, open-air construction work should choose the appropriate weather, wind, rain, cold, etc. should not work.

5, the construction of this project is in a special location, the construction area is small, it is not suitable for mobile scaffolding, high work need to use steel pipe scaffolding.

Construction process

Substrate cleaning→primer coating→top coat coating→inspection and acceptance? Base surface cleaning:? Before painting, should be painted parts of the rust, weld flux skin, welding spatter, oil, dust and other debris cleaned up. The good or bad quality of base surface cleaning out repair is directly related to the quality of the coating.? Grade quality standard descaling method?1 steel surface to reveal the metal color sandblasting shot blasting pickling?2 steel surface is allowed to survive clean rolled skin general tools (wire brush, emery cloth) to remove

Above, I introduced how to brush antirust paint, mainly seven simple steps, these are are all complete and roughly introduced, the specific operation is still according to the physical object. I also introduced? Rust paint construction preparation, preparation is mainly the preparation of some tools, mainly five steps, consumers in need can refer to the introduction of the editorial, I also introduced the rust paint construction process, I hope to help you deepen the understanding of the rust paint.
