There are many types of anticorrosive paint on the market, and you need to choose a suitable one before construction, because the use of each coating is different, so we should choose according to the use of coating and environment. In addition, some anticorrosive paints contain certain harmful gases, so relevant protective measures must be taken in construction, and some cannot be mixed with other materials. When the anticorrosive paint is constructed, the surface of the construction object needs to be treated clean, and there can be no debris and dust on it, otherwise the construction effect will be affected.

At the same time, it is also necessary to pay attention to the quality of the coating, only the best paint can play a good construction effect, and the construction personnel can also have the phenomenon of cutting corners, which will affect the coating effect.

(1) After the concrete cylinder wall treatment, the matrix should be smooth and compact, and the lining surface should be free of oil, slurry, cement foam, looseness, honeycomb, hemp surface and other surface defects.

2) After using putty leveling, the surface should be smooth without local unevenness, and the thickness of putty should not be less than.

3) After mechanical grinding of the protruding bricks, it is required to reach the radius of the arc of the yin corner of > 10mm or more, and the radius of the arc of the yang angle of > of more than 5mm.

(4) Large concrete defects such as holes and spalling are not allowed on the concrete surface. If the requirements are not met, it must be repaired.

5) The flushing water pressure is controlled to completely remove residue and dust.

6) Ensure that the moisture content of the base surface should be less than 6% during construction.

1. Primer

1) Take the pre-prepared appropriate amount of primer, then add an appropriate proportion of supporting curing agent and stir for more than 3min, stir evenly before use. Apply 1-2 coats with a brush or roller, and the amount is about square meters. Apply the first primer to the treated surface of the lining.

2) In the construction of concrete foundation, if the viscosity is slightly higher or in the low temperature construction environment, in order to increase the adhesion between the coating and the base layer, 5-10% solvent can be appropriately added for dilution, and the solvent is suitable for styrene.

2. Glass flake cement

1) Take an appropriate amount of flake cement premix, add an appropriate proportion of supporting curing agent, and stir well. One stirring should be controlled within 30 min, and the initial setting time should be controlled at about 40min.

2) Use a spatula to evenly wipe the construction on the basis of the primer, and the thickness of each construction (after the initial setting) is 15kg channel. The interval between each application is about 12 hours.

3) Under normal circumstances, the construction of 2 passes is sufficient, and under special circumstances (such as the medium contains solid abrasives), the construction thickness can be increased to 3 passes.

4) During the construction process, the construction surface should be kept clean, and if there are protrusions or construction drips, they should be polished and smooth.

5) The end interface of the 2 coats should avoid docking and must be lapped.

<> precautions for the safe construction of anticorrosive coatings are very important, and the formulation of precautions is to better solve practical problems, and the handling of every detail is very critical. Zhongda Consulting will explain to you the precautions for the safe construction of anticorrosive coatings.

Anticorrosive coating is an indispensable coating in paint coatings. Exterior decoration materials can lead to decay due to constant exposure to the wind and sun, and this problem can be avoided if you apply a layer of anti-corrosion paint. However, anticorrosive coatings must be standardized in the construction process to avoid harm to the human body.

Coating operation involves a variety of hazards, in the coating of raw and auxiliary materials, most of the physical and chemical properties such as combustion, toxicity and so on, some materials in the process of operation there are dust hazards, therefore, anti-corrosion coating coating operations should pay attention to safe construction. Work at height: Work carried out by people at a high place based on a certain position.

When working in a building, if the operation is carried out on a shelf of more than 2 meters, it is considered to be working at height. In the anticorrosive coating operation, the proportion of falling from height and object striking accidents that occur in high-altitude operations is the largest. Wearing safety helmets and safety belts correctly or erecting safety nets according to regulations can effectively avoid accidents.

Electrical hazards: Electrical hazards to painting operations not only cause fire and safety, but also involve other safety issues. Electrical hazards include static electricity, lightning, and electric shock.

Static electricity will cause electric shocks to the human body, causing hazards such as burning and **. Lightning is mainly a lightning strike, which destroys electrical equipment and control systems, and causes injury to people. Electric shock accidents often occur suddenly, causing serious consequences in a very short period of time, endangering people's lives.

Chemical Pollution and Toxic Damage: Solvent-based anticorrosive coating products have certain chemical hazards. In the work of Xu Installation, it should be noted that the solvents and thinners in the paint cause air pollution and are harmful to the human body.

Fire, danger: solvent-based anticorrosive coatings, as well as thinners used in coating operations, are mostly flammable and explosive materials, and there are hidden dangers of fire and fire in the coating operation itself. The possible causes of disasters include failure to comply with operating procedures during electrostatic coating, which is easy to produce discharge sparks; Waste paint, paint mist, paint and solvent waste rags are not well stored, and they are easy to produce spontaneous combustion and ignition when they are piled together; Improper selection or use of electrical equipment, or failure to repair in time after damage, insufficient explosion-proof level, etc.; Lightning strikes during the thunderstorm season.

Noise hazards: Sound over 100db is considered strong noise, and people who work under this noise will temporarily reduce their hearing, but can recover. However, hearing loss caused by noise of more than 150db, or even deafness, cannot be recovered.

Therefore, more than 85db must be protected. Noise levels vary depending on the type of equipment and the location and location. Excessive noise requires protection of workers' hearing.

In the construction process of anticorrosive coatings, only by strictly abiding by the above five precautions can the construction safety be guaranteed.

Precautions for safe construction of anticorrosive coatings" are all in Zhongda Consulting Construction Pass, and there is all the relevant building construction information you want.

Murals can give the entire building a more aesthetically pleasing appearance, and they can also protect the walls from falls and cracks when exposed to sunlight. So, how much do you know about the paintings on the walls? Next, let me introduce you to the market and construction methods of anti-corrosion wall construction solutions.

1. There is no specific location for the ** wall paint. I recommend paints, accessories, labor, management, coatings, per square meter**, taxes, etc. They can be converted into ** tables and then calculated from squares, which is much clearer.

You can plan in detail the general aspects of the project, quality control, construction management processes, and other matters;

Wall anticorrosive coating construction planThe ** is calculated together with the labor cost, i.e. the ** of the final exterior wall paint. Second, it involves the location and floors of the actual building. If it is a flat paint, once the bottom, the top layer twice, the market ** is about ten yuan per square meter.

Wall anticorrosive coating construction planDuring construction, first of all, the cement mortar must be leveled on the lower surface. As far as possible, there are no empty surfaces on the surface covering the surface, and there are no gaps or cracks on the surface of the rough grinding surface. The yin and yang angles should be square and vertical.

2. If it is a new wall that has just been brushed, it is necessary to maintain a moderate amount of time in the rock bucket to maintain a certain humidity before construction. At the same time, dirt must be removed from the surface, and loose material must be removed from the surface of the mortar and pestle.

3. Polymer cement mortar can be used for the correction of cracks and dents during processing, but it should be considered that the material is too rough, which will affect the coating area and coating effect.

Wall anticorrosive coating construction planWhen painting, try to avoid operating under the scorching sun, it is easy to make the paint dry too quickly, the water in the lower layer is absorbed, and the paint on the wall is easy to peel off. Therefore, painting can be done on cloudy days, and the method of applying on both sides of the floor is normal.

My summary: The above is my understanding.

Hello dear, <>

Does anticorrosive coating need anticorrosive putty does not need pro-anticorrosive coating wall construction technology 1, new wall coating construction, the bottom layer of building exterior wall coating requires sufficient curing period, and the bottom surface should be dry, solid and firm, and there should be no sand, cracks, looseness and other defects. The surface of the new water mortar concrete must be cured for a fair time, so that it can be "alkalinized" and fully dried. 2. Construction method, exterior wall coating should not be large-scale batch scraping putty, putty layer should not be too thick, coating construction is generally carried out from top to bottom, each painting should be bounded by the dividing line, wall, yin and yang corner junction or downspout.

The material is made of polymer cement putty. Generally, one primer and two topcoats are used. According to the quality of the project, the number of surface coatings can be appropriately increased.

3. Repair putty, putty is a kind of thick slurry coating, which is an indispensable product in the paint painting construction process. Use plaster to level the hollows on the wall and other places, and then use No. 1 sandpaper to smooth out the protrusions, and clean the floating dust attached to them. 4. Maintenance and renovation, the use of paint to decorate the surface of the building, the advantage of being larger than the audit is that it can be renovated within a certain period of time, and the building is generally maintained comprehensively in 4-5 years.

Conduct a comprehensive survey of the exterior wall before construction
