How to ensure the safety of construction during the construction of fireproof coatings

Should you start with **?

Otherwise, there is only a dead end.

The most important factor that needs to be paid attention to in the construction of fireproof coatings is "safe construction", which I summarize as follows:

Purchase qualified fireproof coatings, the quality of fireproof coatings determines the difficulty of construction.

According to the type of fire retardant coating, engineering site conditions and other factors to determine the construction process.

Formulate a reasonable construction plan and safety plan, and strengthen safety management education.

1) Establish a safety and fire prevention fire brigade headed by the person in charge of security;

2) The construction site is clearly divided into fire operation areas, flammable and combustible material yards, warehouses, flammable waste concentration stations and living areas;

3) The road at the construction site must be unobstructed to ensure that the fire truck is unimpeded in case of disaster;

4) The construction site should be equipped with sufficient fire-fighting equipment, and designated personnel should be designated for maintenance, management, and regular updating to ensure that it is complete and easy to use;

5) Smoking is strictly prohibited in the fire-free area of the construction site.

Second, the key points of fire prevention of on-site electrical equipment.

1. All kinds of electrical equipment and lines are not allowed to be overloaded, and the joints must be connected firmly and firmly to avoid overheating or ignition and short circuit. Repair problems immediately if they are found;

2. Flammable, explosive and combustible gases shall not be stored in the site warehouse, and the lighting line shall be protected by pipes, and explosion-proof lamps and lanterns shall be used;

3. Wires through the wall and wires close to flammable materials should be protected by pipes, lamps and flammable materials should generally maintain a distance of 30cm, and high-power bulbs should increase the spacing. Iodine-tungsten lamps are not allowed to be used in the shed;

4. Temporary buildings are not allowed to be erected under the high-voltage line, and combustible materials are not allowed to be stacked.

There are thousands of fireproof materials, and fireproof coatings are very important. So do you know how fire retardant coatings are constructed? What should we pay attention to when using fire retardant coatings? Let's take a look at it together.

First, how to construct fireproof coatings.

1. Before the structure is coated with fireproof coating, the surface of the steel frame should be derusted for anti-corrosion treatment. It is recommended to use epoxy zinc-rich anticorrosive primer, and epoxy anticorrosive primer can also be used. The anticorrosive primer must be done before the application of the fireproof coating can be carried out.

2. The fireproof coating should be fully stirred before construction, and it can be used only after it is uniform.

3. The thickness of the first construction is appropriate, the second construction is carried out after the surface is dry, the coating thickness is appropriate, and the coating thickness should be controlled around the time and right, not exceeding until the specified thickness is reached.

4. The construction environment temperature is 0-40, the substrate temperature is 5-45, and the relative humidity of the air is not more than 90%. Keep the air circulation at the construction site, the wind speed is not more than 5m s, and it is not suitable for construction when condensing on the surface of outdoor operations or construction components.

5. The construction is mainly brushed, and it can also be sprayed, but the material will be wasted by 15-30%.

What should be paid attention to when using fire-retardant coatings?

1. The fireproof coating must be cleaned when it is changed to the appearance of the substrate. If the substrate has been painted before, it must be removed and cleaned before it can be altered and painted.

2. The thickness of the fireproof coating is usually between the time, and the time distance between 8 and 12 hours is better, if the climate is relatively humid and the air humidity is large, the moment can be appropriately serious to alter the first time to tease the second time, and the first time must be sure that the first alteration is dry at the time of the second alteration. The alteration must be chartered and the clear fire protection data must be altered in a balanced and flat manner.

3. The transparent fireproof coating must be heated indirectly between brushing, and can only be changed or sprayed when it is completely transparent.

4. Before coating, the paint should be mixed evenly, if the paint is too thick, a special thinner can be added appropriately, and it can be diluted to the point that it should be painted and not flowing. The thickness of the first brush should be enough to cover the base layer, usually not exceeded.

The above is the explanation of how to construct the fireproof coating and the precautions when using, and we must pay attention to it when decorating and using it.
