How much does fire retardant coating cost a square meter for protection?

It's about a square meter.

Fire-retardant coating is to brush the paint on the surface of the material, which can improve the fire resistance of the material, slow down the spread of flames, or stop combustion within a certain period of time, this kind of coating is called fire-retardant coating, or flame retardant coating.

Fire retardant coating is a special coating used on the surface of flammable substrates, which can reduce the flammability of the surface of the coated material, block the rapid spread of fire, and improve the fire resistance limit of the coated material. It is applied to the surface of a flammable substrate to change the combustion characteristics of the material surface and prevent the rapid spread of fire; or applied to building components to improve the fire resistance limit of special coatings, called fire retardant coatings.

The fire protection principle of fire retardant coatings can be roughly summarized into the following five points:

The fire retardant coating itself is non-combustible, so that the protected substrate is not in direct contact with oxygen in the air;

Fire retardant coatings have a low thermal conductivity, which delays the conduction rate of high temperature to the substrate;

The fireproof coating is heated to decompose non-combustible inert gas, and dilute the flammable gas decomposed by the heat of the protected object, making it less flammable or slowing down the combustion.

The nitrogen-containing fire retardant coating is heated to decompose NO, NH3 and other groups, which are combined with organic free radicals to interrupt the chain reaction and reduce the temperature.

The intumescent fire retardant coating expands and foams when heated, forming a carbonaceous foam insulation layer to seal the protected object, delay the transfer of heat to the substrate, and prevent the object from catching fire and burning or reducing its strength due to the increase in temperature.

Question: How much is the contractor and how much is the package.

1mm30-35 2mm40-45 4mm70-80 packaging is not easy to say, because there are more types.

Question: Is this the unit price of contracted labor and materials?

Is this the unit price of contracted labor and materials?

The contractor asked. Okay thank you.

Question: What about the material kit?

Ask a question, give us an idea.

The above is generally 3 times of wages.

The material cost is mainly the construction cost.

According to the standard construction, it is generally painted with 3 layers, and the amount of material is about 2kg square, and the amount of fireproof coating should be based on the fire resistance limit requirements of the steel structure, and then the thickness of the fireproof coating is determined, and then the outer surface area of the steel structure is calculated, and then the amount of paint is calculated. Therefore, the dosage of fire retardant coatings for steel structures is mainly determined according to the type of fire retardant coating you use (ultra-thin, thin, thick) and fire resistance limit (first-class fireproof, second-class fireproof).

However, this is more troublesome, and it can be calculated according to the amount in the quota.

Steel column: hourly fire resistance limit (thick steel structure fireproof coating must be selected) thickness 23 mm dosage 23 kg.

Steel beam: hourly fire resistance limit (thin type, thick type fire retardant coating can be) Thin type 5 mm, thick type 20 mm Dosage Thin type 6 kg, thick type 20 kg.

Steel purlin hour fire resistance limit (thin, ultra-thin, thick can be) Thickness: thin millimeter ultra-thin millimeter.

Thick type 15 mm, dosage: thin type kg, ultra-thin type 4 kg, thick type 15 kg.

Roughly domestic fire retardant coating production test**:

1.Indoor thin steel structure fireproof coating 3800 yuan - 5500 yuan per ton.

2.Indoor ultra-thin steel structure fireproof coating 12,000 yuan-15,000 yuan per ton.

3.Indoor thick steel structure fireproof coating 2500 yuan - 4500 yuan per ton.

4.Finishing fireproof coating 7500-9500 yuan per ton.

5.Tunnel fireproof coating 2000-3500 yuan per ton.

Unit price of fireproof coatings: There is a gap according to the use site, fire rating, fire resistance time, construction method, construction difficulty, site conditions and other factors. The general material cost is 10-30 yuan per square meter

Different types of fire retardant coatings** vary.

Now there are many businesses selling fireproof coatings on the market, but most people don't know how to distinguish between the true and false fireproof coatings

1. The appearance of fireproof paint is very similar to that of ordinary coatings, which is difficult to identify from the appearance, and it is also difficult to check the quality of fireproof paint on site. Consumers should pay attention to distinguishing between fireproof coatings and ordinary coatings when choosing, so as to avoid shoddy products and fail to achieve fire protection effects, so as to prevent potential safety hazards.

2. Don't be greedy for cheap when buying paints, and be sure to choose products from well-known brands. The "fireproof coatings" on the market are mixed, consumers must shop around when buying, do not be superstitious about the word "green" on the coating packaging, and carefully read the quality of the product qualification test report; Observe whether there is rust and leakage at the joints of the iron drum; Pay attention to whether the clear signs on the iron drum are complete, in case you buy counterfeit "fireproof paint".

3. When purchasing fireproof coatings, you can also check whether the product has a qualified inspection report issued by the fire quality inspection center. At present, the fire retardant coating implements the type approval system of fire protection products, and the fire retardant paint sold on the market should have the national fire protection product type approval certificate and type inspection report.

4. When the qualified fireproof coating is burned by strong fire such as blowtorch, a large amount of foaming and expansion, the surface will gather and convex, and there will be no burning within a few minutes, while the fake and shoddy fireproof coating will basically not foam, and there will be a large number of scattered slag, and the wood substrate will soon be burned and damaged.

5. According to the national standard, in addition to meeting the requirements of fire retardancy, the combustion performance of fireproof paint is divided into first and second grades. Under the specified experimental conditions, the flame resistance time of the first-class fireproof paint is not less than 20 minutes, and the heat-resistant time of the second-class fireproof paint is not less than 10 minutes.

Chengdu Xiateng Building Materials is a professional manufacturer of various fireproof coatings. The products have professional quality inspection reports, quality assurance! Over the years, it has won the trust of consumers, has a good reputation, and is your best choice!

The fire retardant coating changes with the market, and the specific color is unknown, but it is generally 200 400 yuan per square meter.

After decades of development, the production process of fireproof coatings in China has reached the standards of Europe and the United States, so consumers need to prevent wearing "colored glasses" when purchasing fireproof coatings, and take the quality of the product as their own choice, so as to be able to buy high-quality and low-cost fireproof coatings.

In addition, the increase in the brand of fire retardant coatings, to consumers bring a lot of trouble, consumers can query the brand user experience through the Internet, or query the brand's **, so as to be able to choose the right fire retardant coating products more wisely.

In the professional consumer group, fireproof coating is no longer a concept, but the evaluation of all parties, a package of technical testing, corporate brand strength, product functions and other factors, according to the comparison of various indicators, so as to buy their favorite fireproof coating brand.

Misconceptions: Avoid misunderstandings and choose suitable fireproof coatings: different spaces and different materials have different performance requirements for fireproof coatings, so you can ask experienced store salesmen when purchasing coatings, and use suitable fireproof coatings in the right places to use the right fireproof coatings in the right places to achieve the best fireproof effect.

Myth 1: Use fireproof coatings for wood structures on steel structures.

Since the wood structure fire retardant coating and steel structure fire retardant coating are not identified by the naked eye, consumers must know the detailed attributes of fire retardant coatings when purchasing. If the steel structure uses the fireproof coating of the wood structure, its adhesion is greatly reduced, and it is easy to fall off, and the fire safety cannot be guaranteed.

Myth 2: Failure to distinguish between solvent-based and water-based fire retardant coatings.

There are two types of fire retardant coatings for steel structures, solvent-based fire retardant coatings and water-based fire retardant coatings. From the perspective of adhesion, solvent-based is greater than water-based, therefore, solvent-based fire-retardant coatings should be used for outdoor steel structures, and solvent-based or water-based fire-retardant coatings can be used for indoor steel structures.

The fireproof coatings produced by some domestic manufacturers will decompose toxic gases when exposed to fire. If this coating is used in refractory electrical products, toxic gases will be released in the event of a fire. For example, the use of G60 perchloroethylene fire retardant coating, which has been eliminated, will decompose toxic chlorine gas when exposed to fire, so it cannot be used.

The quality of fire retardant coating construction also has an impact on the fire performance of the material, so it is necessary to pay attention to the coating quality of fire retardant coating. The coating method of different fire retardant coatings is slightly different, but the basic construction points are the same.

The first thing to determine is which type of fire retardant coating to use, and how long is the fire resistance time? How thick should the coating be?

Jinchu Blue Shield thick fireproof coating ** is about 3k, but the dry density is small, and the use area of fireproof coating of the same specification is larger, and it is more cost-effective.

As we all know, the price of coating raw materials has begun to rise since 2017, and the logistics cost has begun to adjust in 16 years, so it is not only the unit price of fireproof coatings.

It is recommended to choose Jikun fire protection for the purchase of fireproof coatings.

The ** of one square of fireproof material is:

The amount of fireproof coating should be based on the fire resistance limit requirements of the steel structure, and then determine the thickness of the fireproof coating, and then calculate the surface area of the steel structure, and then calculate the amount of paint. Therefore, the dosage of fire retardant coatings for steel structures is mainly determined according to the type of fire retardant coatings used and the fire resistance limit (primary fire protection, secondary fire protection). How much is the steel structure fire retardant coating per square meter is calculated according to the building fire resistance grade and the type of fire retardant coating, the construction process of the fire retardant coating, the difficulty of construction and other factors.

Generally speaking, the first-level fire prevention is 45 yuan to 80 yuan per square meter, and the second-level fire prevention is about 30 yuan per square meter. Specifically, according to the region, the materials used, and the height of the building, the fireproof material is determined by one square. When purchasing, you should carefully read the quality inspection report of the product; Observe whether there is rust and leakage at the joints of the iron drum;

Pay attention to whether the clear signs on the iron drum are complete, in case you buy counterfeit "fireproof paint".

Jikun fire brand strength is strong, set development, scientific research, production, sales as a whole, with standard modern production workshops, multiple production lines, a number of logistics cooperation companies, more convenient delivery; At the same time, the manufacturer provides a five-year warranty; It also has an exclusive engineering team, which can undertake construction and acceptance of contractors and materials.

The first level of fire retardant coating per square meter is determined according to: building fire resistance grade, type of fire retardant coating, construction technology, construction difficulty, etc. Generally** is between 30-100 yuan.

How much is the fireproof coating is determined according to the building fire resistance level, the type of fireproof coating, the construction process, and the difficulty of construction, which is about ten or twenty yuan per kilogram, a few yuan for the cheap, and one or two hundred yuan for the expensive. And to determine which type to use, and how long to withstand fire? How thick should the coating be?

The engineering requirements, fire ratings, and the different uses of the first class are not the same.

Do the math how much it will cost you to renovate your home

Fireproof coatings are probably used in the kitchen when decorating, and there are still many things to pay attention to during the construction of these functional materials, and the following points for you can take a look: 1The surface of the substrate should be cleaned before construction, and if the substrate has been painted, it must be stripped or sanded with water sandpaper to expose the wooden substrate before painting.

2.Before the transparent fireproof coating is painted, indirect heating (water bath) is used to completely transparent until it is completely transparent, and then it is evenly stirred, and then it can be sprayed or brushed. 3.

The thickness of each brush is, the painting interval is 8-12 hours, if the climate is humid and the air humidity is high, the time of the second brush can be extended according to the actual situation, so as to ensure that the next one is painted after the last road. In addition, it is necessary to ensure the smoothness of the transparent fireproof coating film when painting. 4.

The reference theoretical dosage of transparent fire retardant coating is 500g. After the primer is thoroughly dried, apply two topcoats to ensure smoothness and beauty. The temperature of the construction environment is required to be 5-35, and the relative humidity is below 40%.

Different types of fire retardant coatings are not the same. If you are engaged in indoor thin steel structure fireproof coating, it is generally 4500 per ton.

This is set according to the requirements, generally about 30.

Fire retardant coating** is determined according to the engineering requirements and fire rating requirements.

According to the fire rating, the project requires a price. Generally, those who buy materials can also be constructed.

How much is a square meter of fireproof material 2-8 mm spray steel workshop.

Summary. Dear, I am very honored to answer for you, to make a square meter of fireproof coating is about 10-20 yuan per square meter. Generally, the construction of fireproof paint covers a large area of the site, and the material is about 13-17 pieces per square.

How much does it cost to make a square meter of fire retardant coating? Labor costs.

Dear, I am very honored to answer your lenient rent, and do a square meter of Hu Zhaohuo paint in 10-20 yuan per square meter. Generally, the construction of fireproof paint covers a large area of the site, and the material is about 13-17 pieces, and the liquid is made of one square.

Extended information: Scraping and coating, which is the most common. It is to use manual scraping tools such as glass scrapers and hard rubber sheets to scrape off the excess fireproof coating on the substrate or in the crevices after conventional application.

This method is laborious and prone to material waste, and is generally used for floor coating. The roller coating method is also a frequently seen application method. Apply paint to the roller, then grab the end of the pole and hold it down to roll back and forth to stick the paint to the wall.

The roller is hollow in the middle, cylindrical in shape, with long pile made of synthetic fibers glued to the surface, and a stick for long-distance application. The roller coating method is long and laborious, and is generally used for wall painting. The brush method is somewhat similar to the roller method, but the stick is shorter, so it can only be applied at close range.

The brushing method can enhance the adhesion of the surface of the paint by applying force to its short force, and the brushing method can also be applied more comprehensively and meticulously in the details of the attack, but its efficiency is low and it is also very troublesome. Theoretically, the brushing method can be applied to walls and other surfaces of any shape. Spraying, spraying is a relatively new way of applying, and it is less common than the other three.

The spraying method mainly uses a spray gun to atomize the paint and then spray it on the surface of the substrate. Relatively speaking, this method has the highest application efficiency and a more uniform surface quality after spraying, but it has high technical requirements for workers, and the mist gas is easy to be inhaled into the body and may cause potential harm.
