To Solve The Coating Anticorrosion Insufficient Small Expert - fumed Silica

Why does coating corrosion occur?

The coating itself: Some coatings contain corrosive substances, such as phenolic resin coatings containing free phenols, which will cause corrosion to the metal surface under certain conditions.

External factors, such as temperature, humidity, oxygen, pollutants, and other environmental factors, as well as improper metal surface treatment, may cause corrosion. For example, the metal surface is not thoroughly cleaned before painting, leaving impurities such as stains and grease, or the primer is not used as required, which may lead to corrosion.

Internal coating factors: There are pores and cracks inside the coating, and these defects may cause corrosion. The cracking, foaming, or peeling of the layer under the influence of environmental factors causes the coating to lose its protective effect on the substrate.

Coating adhesion problem: The adhesion between the coating and the substrate is insufficient, resulting in the coating easily peeling or peeling, thus losing its protective effect on the substrate.

Chemical media intrusion: water, acid, alkali, and other chemical media penetrate the coating through the pores and cracks of the coating, and chemical or electrochemical reactions occur with the metal surface, resulting in corrosion.

Coating aging: Affected by ultraviolet light, temperature, humidity, and other factors for a long time, the coating may appear aging phenomenon, such as cracking, powder, etc., thus losing its protective effect.

Properties of fumed silica:

Fumed silica is an amorphous silica with a nanoscale particle size, with an average particle size between 10-20 nanometers. Its unique structure and properties give it the following advantages in coatings:

Enhance the density of the coating: fumed silica nanoparticles can be filled in the pores and cracks in the coating, improving the density and coverage of the coating and reducing the possibility of penetration of corrosive media.

Improved coating adhesion: fumed silica nanoparticles can form a chemical bond with the organic polymer material in the coating, thereby improving the adhesion between the coating and the substrate and preventing the coating from peeling.

Enhanced wear and weather resistance of the coating: fumed silica nanoparticles can be evenly distributed in the coating, increasing the hardness and toughness of the coating and reducing scratches and wear while improving the weatherability and UV resistance of the coating.

The application of fumed silica in paint anticorrosion:

As a functional filler, fumed silica has a broad application prospect in coating anticorrosion. The following are the main application directions:

Anticorrosion coatings: fumed silica can be used as an additive to anticorrosion coatings to improve the anticorrosion properties of coatings. By introducing fumed silica into the coating, the compactness, adhesion, and wear resistance of the coating can be enhanced, thus effectively preventing the penetration and erosion of corrosive media.

Weather-resistant coating: fumed silica can improve the weather resistance of the coating so that it can maintain good performance when exposed to ultraviolet light, moisture, pollutants, and other environments for a long time. This helps to extend the life of the paint and maintain the aesthetics of the painted surface.

High-temperature coating: fumed silica has good thermal stability and can maintain good performance in high-temperature environments. Therefore, fumed silica can be applied to high-temperature coatings to improve the heat resistance and oxidation resistance of coatings to meet the need for corrosion protection in various extreme environments.

Heavy anticorrosive coatings: For occasions that need to withstand long-term corrosion of corrosive media, such as Marine environment, chemical equipment, etc., fumed silica can be used as an additive for heavy anticorrosive coatings. 

The advantages of fumed silica in solving the insufficient anticorrosive coating:

Compared with traditional anticorrosive coatings, anticorrosive coatings with fumed silica have the following advantages:

Improved corrosion resistance: fumed silica can help extend the service life of the substrate and reduce the frequency of maintenance and replacement.

Reduced maintenance costs: By using fumed silica as an additive, you can reduce the amount of traditional anticorrosion coatings used. This is because fumed silica has high filling properties and can achieve good corrosion protection at lower concentrations. This helps to reduce painting costs and maintenance costs.

Strong adaptability: fumed silica has good chemical and thermal stability and can adapt to various environmental conditions and harsh application requirements. Whether indoor or outdoor, room temperature or high temperature, dry or humid environment, fumed silica can play an excellent anticorrosion effect.

Environmental protection and safety: fumed silica is a non-toxic and harmless nanomaterial, harmless to the environment and the human body. Compared with the toxic and harmful chemicals used in traditional anticorrosion coatings, the use of fumed silica is more environmentally friendly and safe.

Maybe you need concrete foaming agent for building curtain wall

Architectural decoration refers to various treatments on the internal and external surfaces and spaces through decorative materials or decorations. The function is to safeguard the primary structure of the building, improve the physical efficiency and use functions of the structure, and beautify the structure. The building decoration sector is among the essential components of the building market. It is listed as the 3 major components of the building and construction industry in addition to the housing and civil design building industry and the building and setup sector. Based on the nature of use, the building decoration industry can be divided into three categories: public, residential, and curtain wall decoration.

concrete foaming agent 

Unlike the civil construction industry, equipment installation industry and other engineering businesses that are completed once, the demand for architectural decoration runs through the entire life cycle of the building. After the building is completed, users may still carry out architectural decoration projects during use.

Among them, a curtain wall is a non-load-bearing external covering on the periphery of a building, where the exterior wall is non-structural. Since the drape wall surface area is non-structural, it can be made from lightweight materials, such as glass, potentially minimizing building and construction prices. Another advantage of glass is that natural light can penetrate deep into the building. The curtain wall facade does not bear any structural load of the building except its weight. The wall is the primary building framework. After that, lateral wind lots happen through links at constructing floorings or columns. Drape walls are designed to resist air and water infiltration, soak up guide brought on by wind and seismic pressures acting on the building, withstand wind loads and support its weight.

concrete foaming agent 

Curtain walls can be designed as an integrated “system” of framing, wall panels and weatherproofing materials. Steel frames have largely given way to aluminum profiles, often filled with glass, which provides benefits such as a handsome architectural appearance and daylighting. However, when large amounts of glass infill are used, the impact of light on visual comfort and the temperature generated by solar exposure in the building is more difficult to control. Common curtain wall materials include stone veneers, metal panels, louvers, and operable windows or vents.

The curtain wall design spans multiple floors. In addition to considering design requirements such as thermal expansion and contraction, it also considers the swing and movement of the building, seismic requirements, water diversion, and thermal efficiency.

Application of concrete foaming agent in building curtain walls

Curtain wall windows built into the opening require a foaming agent. This is because the foaming agent aims to seal, fill, insulate, heat insulate, soundproof, delay rainwater infiltration, and help interior construction.

More than a hundred schools in the UK have been closed due to the risk of collapse

In the UK, more than 100 schools were closed because of the danger of collapse

In the UK, many schools use RAAC (autoclaved aerated cement) This is a concrete material that is lighter.

In 2018, the roof of a school in southeast England fell down. Later, it was discovered that RAAC material had been used for the roof as well as the buildings. This raised safety concerns.

BBC reported that RAAC materials were widely used from the 1950s until the mid-1990s in areas such as roof panels, and had a lifespan of around 30 years.

Reports indicate that the risk of building collapse is not limited to schools, but can also be found in hospitals, police station, and other public structures. RAAC material has been found.

The Royal Dengate Theatre at Northampton is temporarily closed after RAAC material was found.

According to NHS, RAAC has been detected in 27 hospital building.

The NHS chief has been tasked with developing measures to address the potential collapse risk.

BBC reported that since 2018 the British government has warned schools to be "fully ready" in case RAAC is found within public buildings.

The Independent reported Jonathan Slater - a former senior education official - that Sunak, Prime Minister in 2021, approved budget reductions to build schools while he was the chancellor of treasury.

Nick Gibb is a senior official at the Department of Education. He said that the Department of Education asked for PS200m annually for school maintenance. Sunak, then the chancellor, only provided PS50 million per year.

The report also states that despite Sunak having promised to renovate at least 50 schools every year, in the main reconstruction plan of the government only four schools were renovated.

The British National Audit Office chief also criticised this crisis. He claimed that the Sunak government had adopted a "plaster-method" of building maintenance.

He believes the government's underinvestment has forced schools to close, and that families are now "paying the cost".

Paul Whitman is the secretary-general of National Association of Principals. He said that the public and parents would perceive any attempt by government to shift blame to individual schools, as a "desperate attempt to divert attention away from its own serious mistakes."

Whitman claimed that the classroom has become completely unusable. Whitman blamed the British Government for the situation. "No matter what you do to divert or distract, it won't work."

London Mayor Sadiq khan said that the government should be open and transparent. This will reassure parents, staff, children, and others.

BBC reported schools in the UK were pushing forward with inspections and assessments. Children who had been suspended because of school building issues will be temporarily housed, or they can learn online.

High Purity Nano Hafnium Hf powder CAS 7440-58-6, 99%

Hafnium Powder is a metal made from hafnium. The most common method to prepare hafnium from sponge hafnium involves hydrogenation and deshydrogenation. Purity>99%
Particle Size : 5-10 Micron

Hafnium Nanopowder:
Hafnium Hafnium on the periodic table : Group 4, Atomic Number d-block, Mass 178.586.
Hafnium a shiny silvery metal. It's resistant to corrosion due to the tough, impenetrable film of oxide that forms on its surface. Hafnium metallicis unaffected by acids or bases except hydrofluoric. Hafnium element can be difficult to separate because they have the same atomic sizes.
Hafnium Powder is a dry, light gray metallic powder. The dry powder reacts when it comes into contact with water, producing hydrogen. This is a flammable liquid. The reaction could produce enough heat for hydrogen to ignite.

Hafnium can be found in zirconium minerals. It is a ductile, brightly glistening metal. It is extremely strong and resistant to corrosion. Zirconium, hafnium and other metals have nearly identical chemical properties. (Hafnium however is twice as dense.) This makes them difficult to separate. Hafnium's properties is affected by zirconium.

Product characteristics of hafnium:
It is highly anti-corrosive, resistant to acid and alkali erosion, and soluble in Hydrofluoric Acid to form fluoride complex. Hafnium at high temperature can be combined with oxygen and nitrogen to form nitride. Hafnium powder is easy to burn.

What is Nano hafnium hf powder ?
The invention relates a superfine, high purity hafnium and a method for preparing it.
Prepare:
1..The hafnium dioxide powder and reducing agents powder in a molar ration of 1:1 to 1:2 were mixed evenly, and packed into the furnace crucible.
2. The crucible should be placed in the reaction vessel, covered and vacuumed, then filled with argon to wash, heat and reduce, followed by constant temperature reduction.
3. After vacuum, argon is added for cooling under argon's protection.
4 washing: first, pickle the product and then wash it with deionized water. Then, screen, dry, and you will have ultra-fine, high purity hafnium.

Nano Hafnium Use:
Hafnium powder can be used to produce hafnium-alloy materials such as hafnium metal sputtering targets. It has high heat absorption properties and is exothermic (1 times faster that zirconium, titanium and other alloys), and it can also serve as a structural material for missiles and jet engines.

The hafnium refractory is useful for turbojet aircraft blades in freezing point pressure jet engine. Hafnium powder is also used to manufacture valves, high-temperature components and nozzles.

Hafnium rods are used for the majority of nuclear reactor control rods.
Hafnium alloys are used in the production of tantalum, titanium, and other metals. C103 alloy is used for liquid rocket thruster nodes, like the main engine in the Apollo lunar module. C103 is composed of 89 per cent niobium and 10 per cent hafnium.

Hafnium, because of its high heat resistance, is an excellent scavenger for nitrogen and oxygen in inflatable and incandescent lights. Hafnium, which can release electrons in the air, is also used for plasma cutting.

Storage condition of Hafnium Hf powder:
Hafnium Hf Powder cannot be exposed to the air. The powder should be packed in vacuum and kept in a dry and cool room. Hf Powder should also not be exposed to stress.
