Fireproofing paint for steel structures and important standards to know

 Fireproofing paint for steel structure is a fireproof solution applied in many factories, industrial zones, factories and large constructions. So what are the characteristics of fireproof paint for steel structure? What is the standard for this paint? Today's article will help you know more information about this fireproof paint.

Learn how to apply fireproofing paint to steel structures of current works

First, we will talk about the characteristics of fireproofing paint for steel structures. Next, we will introduce 5 solutions that can be combined with this fire protection measure. Finally, there is the standard for implementing fireproof paint.

  1. What are the characteristics of fireproofing paint for steel structure?

The composition of fireproofing paint for steel structure includes Epoxy resin, Poly Phosphorus flame retardant, organic solvent and insulation foaming agent. The ingredients in the paint will slow down the heating and spread of the fire. Fire retardant paint also works to reduce toxic gas emissions from the fire. The paint layer will protect the steel structure for a certain time, avoiding the steel being heated and broken.

  1. Fireproofing paint for steel structures is also combined with what solutions?

Fireproofing paint for steel structures can be combined with other fire protection measures to increase fire resistance:

  • Intumescent coating

These coatings are also known as intumescent paints. The intumescent coating can expand to 100 times the original thickness to protect structural steel from flames. Intumescent coatings will spontaneously chemically react and swell when exposed to extreme heat. This product is applied as a fireproof paint to steel structures.

  • Liquid convection cooling

This fireproof solution was first patented in the 19th century. If a fireproof coating for steel structures is to be applied on the outside of the surface, then this fire protection method will be installed inside the steel structure. If there is a fire, cool water will flow evenly into the steel structure affected by the fire and cool down the structure.

  • Fire Extinguisher Sheet

Flame retardant panels are designed for specific needs and can be used as a fireproof material. This method is very practical, but produced in limited quantities. This method meets almost all safety codes and standards. The fire extinguishing sheet can withstand temperatures up to 700 degrees Celsius without melting, no burning, no shrinking. If fireproof paint for steel structure will help limit the spread of fire, the fire extinguishing sheet will help put out the fire and protect the body. When a fire occurs, people in the fire can put a fire extinguisher on their body and find a way out.

Fireproof rigid boards have different thickness and can be easily installed during construction, installation of steel floor and beams. These boards have good moisture resistance and fire resistance. Rigid boards can be heat and soundproof.

  • Autoclaved aerated concrete

Autoclaved aerated concrete can strengthen and provide fire resistance when needed. This type of concrete can withstand heat up to 1200°C and does not catch fire, thus limiting damage. When suddenly sprayed with water to put out the fire, the texture of the concrete does not change..

  1. Standards for the performance of fireproofing paint for steel structures

  • Step 1: Check the regulations, technical information of materials used in the construction.

  • Step 2: Measure and design the grid (if any) to suit the structure of the building.

  • Step 3: Determine the thickness of spray paint suitable for the structure, meeting the fire resistance requirements of the building.

  • Step 4: Plan to deploy as well as arrange human resources.

  • Step 5: Make sure the coatings are applied according to the manufacturer's specifications. Ensure every surface of the mesh is covered with fire retardant paint for the most complete steel structure for constructions requiring mesh.

  • Step 6: Strict coating monitoring and testing during construction is carried out by qualified personnel.

  • Step 7: Repaint the areas that have not met the required quality.

  • Step 8: Let the paint dry according to product specifications, and do not affect the surface.

  • Step 9: Complete the process, conduct product acceptance.


The above are important standards when implementing fireproofing paint for steel structures. You can refer to other articles if you want to know more about fire protection measures.

Boiler Tube Repair - Learn some ways to restore Diesel engine high pressure pumps

Image
Proper repair, calibration and Boiler Tube Repair (restoration of high-pressure diesel pumps) will help increase the life and performance of the pump. Let's learn about some common high pressure pump failures as well as how to restore them effectively. Before Boiler Tube Repair, let's find out what a high pressure pump is? To restore an effective high pressure boilers ( Boiler Tube Repair ), you need to learn some general information about this pump in advance. Diesel engine high pressure pump, also known as high pressure oil pump, is a device in the diesel engine fuel system that pumps fuel to high pressure through the high pressure oil pipe to the injector. fuel into the combustion chamber. The task of the high-pressure pump is to help the engine operate at maximum capacity but still save fuel and minimize emissions to the environment.

Solar Installation - How to install and should we install?

Image
The process of solar installation is not too complicated. Still, the implementation process requires a lot of experience and technical knowledge. Therefore, solar power installation needs to follow the correct procedure to ensure accuracy and safety. What is solar installation and how do solar panels work? When installing a solar power system, we need to use solar panels. A solar panel consists of a layer of silicon cells, a metal frame, a glass shell element, and a wiring system to transmit electricity from the silicon. Silicon is a nonmetal with conductive properties that allow it to absorb and convert sunlight into usable electricity. When light hits the silicon molecules, the light causes the electrons in the silicon to move, creating an electric current. This is known as the "photovoltaic effect" which describes the general function of solar panel technology. The process of the solar installation system needs to be done correctly The most common location to install sola...

Solar system installation - The advantages and disadvantages

Image
Using solar energy is becoming more and more popular in many countries. In the UK, more than a million households already use solar energy. In this article, we will explore some of the advantages and disadvantages of solar energy and consider whether or not to do solar system installation . Before making a solar system installation, take a look at the advantages of this energy. Before doing a solar system installation , you should learn about the benefits of this clean and endless green energy:  1. Solar system installation gives you an endless source of renewable energy Among all the benefits of solar installation , the most important is that this energy source is infinitely renewable. It can be mined in all regions of the world and is available every day. Unlike some other energy sources, we cannot use all of the solar energy. According to scientists, solar energy will be usable as long as we have the sun so that sunlight will be available to us for at least 5 billion years. 2. S...
