Application of Nano silica powder

/ / no Comments

Nano-manufacturer (aka. Technology Co. Ltd. summarized specific applications of Nanosilica after years exploring Nano-powders.
Plastic
Nano-silica Light-transmissive with a smaller particle size. This can make plastics dense. When silica is added to polystyrene, it improves the film's transparency, strength and toughness, as well as its waterproofing and anti-aging capabilities.

Rubber
Rubber is an excellent elastomer that has good stretchability. However, its overall performance isn't satisfactory. Carbon black is added to rubber to improve its strength, wear resistance and aging resistance. Carbon black is added to rubber, but this results in a black product. The grade of the rubber is low. The introduction of nano-SiO2 to China has provided a solid material base for the production a brand new generation of rubber goods with unique colors and high performance.
When rubber is treated with nano-SiO2, its abrasion, tensile, flexural, and ageing resistance all improve. Its color also becomes brighter and has a better color retention.
Dye
Organic dyes may have vibrant colors and strong tinting powers, but they are not as resistant to light, heat, solvents, or migration than inorganics. Addition of nano-SiO2 to organic dyes improves their anti-aging and brightness properties.

Ceramics
Using nano-SiO2 Instead of adding traditional Nano-additives to ceramics, the particles can also be used as second-phase particles. This not only increases the strength and toughness but also increases the hardness and modulus of elasticity of the ceramic. The performance is better and the effect is more optimal than traditional Nano
additives.
By using nano-SiO2 in the composite of ceramic substrates, not only is the density, toughness, smoothness and smoothness improved, but the sintering temp greatly reduced. The application of nano-SiO2 to ceramic products, such as ceramic filter and corundum ball is also very important.

Sealant Adhesive
Sealants, adhesives, and other important products are widely used and have many applications. This requires the right conditions in terms of product viscosity (liquidity), curing speed, and cure time. Nano-materials have been used as modifiers in many foreign products. Nano-SiO2 has become the most popular. It is mostly coated with an organic material to make nano-SiO2 more hydrophobic, and then added to the sealant. It is formed quickly a silica-like structure, i.e., the Nano-SiOX small particles form a web structure that inhibits colloids from flowing, speeds up the curing, and enhances bonding. A small nano-SiO2 size increases both the sealing and the impermeability.

Glass Product
The FRP materials are light, have high strength and corrosion resistance but have poor wear resistance. Scientists use ultrasonic dispersion to add nano-SiO2 into the gelcoat resin. They then compare the performance of the gelcoat with and without the nano-SiO2. nano-SiO2 Wear resistance has increased 1 to 2x. Nanoparticles are grafted and bonded to organic polymers, increasing the toughness and impact resistance of the material. Heat resistance is greatly improved as well, as mentioned above.

What is Nano Silica Nano silica Is a type of organic chemical material. Amorphous white powder that is non-toxic and tasteless. It also has a flocculent quasi-granular structure.
Stable, non-soluble in acid, water, and organic solvents (except for hydrofluoric Acid), nano silica can also be soluble and soluble with alkali, hydrofluoric, and alkali. You can increase the strength and aging resistance of other materials by using its exceptional properties like light, electricity and force. Si-O–Si bonds are what determine SiO2's chemical stability. This bond is gaining more popularity in the material industry due to its exceptional properties such as being low-priced, resistant to high temperatures, corrosion resistance and good insulation.

Silica Nanoparticles, which are inorganic and non-metallic organic materials, have small sizes and a large surface area. This material is non-toxic, tasteless, and free of pollution. It has high strength, stability, and low cost. A transmission electron microscope test revealed that the nano-material has a flocculent and reticulate quasiparticle structure. Silica nanoparticles have a size range of a few nanometers up to several hundred of nanometers. The surface electron distribution, molecular arrangement and other characteristics of silica particles are quite different from macroscopic material. Many of the major characteristics of nanoparticles include light, electricity and heat as well as sound and magnetism.

What is monocrystalline silicon?

/ / no Comments

What is Monocrystalline Silicon? According to the directions of crystals, monocrystalline and polycrystalline silica are divided.
Monocrystalline Silicon describes a substance made from some combination of silicon atoms. Once the molten, elemental silicon has solidified, silicon atoms can be arranged in many crystal nuclei to form a diamond lattice. These nuclei can grow into grains of the same plan direction and form monocrystalline silicon.

Monocrystalline silicon properties
Monocrystalline silicon exhibits quasi-metallic properties and low conductivity. Additionally, its conductivity rises with temperature and it has considerable semi-conductivity. Intinctive semiconductors are made from ultra-pure monocrystalline silicone. To ultra-pure monocrystalline silica, trace III An elements like boron can be added to increase conductivity. Likewise, adding trace V An elements (such as phosphorus and arsenic) can enhance the conductivity to form N-type Silicon semiconductors.

How does monocrystalline and multicrystalline silicon differ?
Once the molten elemental silica solidifies, silicon atoms form into many nuclei. Monocrystalline silicon forms if the nuclei are formed into grains that have the same plane. Polysilicon, however, is formed if the nuclei become grains with different plane directions. There is little difference in the physical properties of polysilicon and monocrystalline silica.
The raw material to make monocrystalline silicon is polysilicon. Polysilicon also serves as the basis for photovoltaic energy generation and solar cells. Monocrystalline silicon may be considered to the most pure substance on the planet. For general semiconductor devices, silicon purity must exceed 6N. For large-scale integrated systems, the requirements are more stringent and silicon purity must be at least 9N. Monocrystalline silicon is currently available with purity levels of 12N.

Why is monocrystalline silica used in
It is used mainly in solar cells. It is the first application of silicon solar cell. This has the highest conversion efficiency and mature technology. Silicon solar cells is used in areas that have low light, low intensity, and high labor cost such as aerospace. Numerous scientific research institutes and manufacturers of monocrystalline silicon batteries have created high-efficiency monocrystalline silicon batteries by using different battery processing technologies and wafer treatment.

How can you create monocrystalline silicon.
Preparation of monocrystalline silicon requires the realization of the transition from polycrystals to single crystals. That is, the atoms of the liquid phase are transformed directly from random to orderly arrangement to asymmetrical structures and vice versa. This is not a complete transformation, but it is achieved gradually through movement at the solid-liquid interface. To realize this transformation, polysilicon needs to undergo transformation from solid to molten and finally to solid crystal silica. It is possible to make monocrystalline silicon out of molten silica. The crucible Czochralski technique and the noncrucible suspension area melting method are the most popular. They are called CZ and FZ respectively.

Silica Gel Density G cm3

/ / no Comments

silica gel density g cm3 is the pore volume of silica gel in units of grams per cubic centimeter. It is a very important factor in the preparation of silica aerogel. This material is hydrophobic, lipophilic and adsorbs organic compounds.

Water vapor sorption isotherm of silica gel at 23 degC, 80% RH [47,52] has a pore volume of 0.35 g water/g of dry silica gel. This value is within the range of literature values, e.g., 0.40 to 0.43 g water/g of dry silica [47,52].

Adsorption kinetics of hexamethyldisiloxane and trimethylchlorosilane onto hydrophobic and lipophilic silica aerogel were studied by using an in-situ polarization technique at ambient temperature and RH. The adsorption time was about 0.4 time for the silica aerogel and 10 times for the hexamethyldisiloxane. It was also found that the adsorption rate increased with increasing v% of DMF solution.

Synthesis and characterization of adsorbents for atmospheric water harvesting (AWH) systems are important aspects in developing such applications. In this study, a sorbent composite of activated carbon fiber felt (ACFF) modified by silica sol and impregnated with hygroscopic salt lithium chloride (LiCl) has been prepared and evaluated for dynamic water uptake, equilibrium water uptake, textural and thermal properties.

The adsorption capacity of the composite samples ranged from 0.85 to 5.0 g/g at 30 v% ethanol solution and was significantly improved with a little increase in v%. This suggests that the adsorption properties of silica aerogel are dependent on its surface hydrophobicity and lipophilicity.

Features and Main Applications of Silica Aerogel

/ / no Comments

The main features of silica Aerogel

Silica aerogel's unique structure gives it the properties of high heat insulation and low sound transmission. Water glass is a rational choice when making silica jelly. Water glass is an alkali silicate made from silicon dioxide, alkali oxides and water. It is also known by the name sulphuricine. Water glass can be classified into two types by the alkali metallic, which are potassium water glass or soda water glasses. This stage shows that silica aerogels can be prepared using low-cost silicon sources.

Silica aerogel's main purpose

1. Thermal insulation

Thermal insulation is the most popular use for silica gel. Silica aerogel is thermally conductive at a level below 0.02W/(m*k), which is lower than that of air. Silica aerosol has the highest thermal insulation properties in the current process. It is ideal for national defense, industry, scientific and research purposes, especially in the field of navigation and aerospace. It can also serve as a pipeline insulation. It is used for heat insulation glass, clothing warmth, and refrigeration heat insulation.

2. Catalyst and catalyst

Silica gel's strength and heat transfer can be continually improved through research and development. This can allow silica aerogel to be used in catalyst carriers and catalysts. Organic fusion of SiO2 & TO2 or cohydrolysis Si and metal alkoxide can produce TO2-SiO2 Aerogel. This will increase silica aerogel's specific surface area and adsorption efficiency.


3. Acoustic delay

Because silica gel is porous, it transmits sound through the pores. There will be significant energy loss at this point, which reduces sound wave amplitude and slows down sound speed. Aerogels can also transmit very little in solid materials. This silica aerogel, which is based on silica, has a high speed and a large acoustic interference propagation range. It also has the benefits of corrosion resistance as well as aging resistance and high temperature resistance. Silica aerogel can now be used in ultrasonic instruments, acoustic instruments, soundproof windows.

What is Nano Silica?

/ / no Comments

What is Nano Silica? Silicon Dioxide Nanoparticles also known by silica nanoparticles and nano-silica appear in the form white powder.
According to the structure of nanometer silica particles, they can be divided into P and S types. P-type silica particles are distinguished by their large number of nanopores. Their porosity is 0.61 mL/g and have higher UV reflectivity than S type particles. They also have a very small surface area.
Nano silica features a light volume, fluffy bulk density, less than 0.15-0.2g/cm3, an area specific of more than 500m2/g, high chemical activity, and a large surface area.
The surface of nano silica contains an OH bond. This makes it a silicate group type of acid oxide. It has hydrophilic water absorption rates that exceed 5 times their own.
Silica nanoparticles have many uses. They are used as additives in rubber, plastic manufacturing, reinforced fillers for concrete and other building materials and as a stable, nontoxic platform for biomedical purposes such as drug delivery or therapeutic diagnostics.

What is Silica?
Silicon (or simply silicon) is one of the many chemical elements found in the earth’s crust. Its oxide forms include silicate (SiO4), and silicon dioxide [silica, SiO2].
It is common to use silicon in industry. The oxide form is often used in biomedical and industrial applications. SiNPs are rare because of their unique properties. These include ease of synthesis and surface modification, strong mechanical property, and relatively inert chemical structure. They have been used in biological materials for many decades.
Silica can be found in two forms, crystalline and amorphous. Although they share the same molecular structure, these two basic forms of silica have very different structural arrangements. Crystalline silica features a regular lattice arrangement while amorphous is more irregular. There are many forms of crystalline silica. Alpha-quartz is the most well-known, and can be transformed by heating to b-quartz or squamous silica. Porosils are porous crystalline silicon, which is also known as porous silica. All porosils come from synthetic materials.
Because of their rare properties (high surface area, high volume, adjustable pores, good chemical and thermal stability, and large pore size), silica and mesoporous silicone are great candidates for controlled drug releases. There are three main types of amorphous silicon: natural, byproducts, and synthetic. Because of its biocompatibility with other elements and stability, amorphous silica has been considered a very promising candidate for molecular image and gene carrier. It is used in dietary supplement, dental fillers, catheters, implant, and implant therapy.

What uses is nanosilica?
Nano silica can be used to modify cement concrete's dispersion, plasticity and temperature. It gives it impermeability, enhanced permeability, frost resistance and reduces hydration heat.
It can be used as a vitrification agent, strengthening agent, adhesive, and glue of ceramics, enamels and glazes. It is also used as a high thermal binder in engineering-grade and refractories.
Use nanocomposite materials modifier as an inorganic adhesive at high temperature. Also used as an additive to inorganic composite materials for strengthening, molding and filling of rubber/polymer material. Additionally, it can be used in a variety of resin engineering material; High-quality FRP packing that is corrosion-resistant.
It is used to cement seal oil wells and as reinforcement material for under-ground engineering.
Use for special purposes, including lamp paint, lubricating oil, thickener or steel dehydrogenate and inner wall paint sensitive material. For solar cells and power cell energy storage.

Is nano-silica toxic?
Exposed to silica, particularly crystalline, has been extensively researched.
Studies have shown that workers are exposed to crystalline silicona at work, which can lead to silicosis. This is a fibrotic lung condition that can also be caused by other diseases such as lung cancer, emphysema, or tuberculosis.
Amorphous silica used to be considered less toxic than crystalline. Recent research has shown that SNPs that are amorphous have toxicity levels similar to crystalline particles. SiNPs' physicochemical and crystallinity also produce different levels of toxicity in vitro as well as in vivo. Consider safety and possible adverse effects, especially those that may affect the immune system.

What is Fumed Silica?

/ / no Comments

Fumed silica can be described as a fine white powder that is made by hydrolysis of silicon hailide at high temperature under an oxyhydrogen flame. It is a form of amorphous silicone dioxide product. The primary particle sizes are between 740nm to 200-500nm. Aggregate particle sizes range from 200-500nm to about 200-500nm. Specific surface area is 100400m2/g. High purity SiO2 content is not below 99.8%. There are a number of silica-hydroxyl groups in the vapor phase silicaaggregates that have untreated surfaces. One is an isolated, unperturbed free hydroxyl molecule; the other is bonded silyl group that is linked and forms hydrogen bonds to one another. The vapor-phase silica aggregates have the untreated surfaces. They contain multiple -Oh compound, which can easily form an uniform three-dimensional network structure in the liquid system (hydrogen bond). This three-dimensional network structure, called the hydrogen bond, is formed by external force (shear, electric, etc.). This three-dimensional network structure (hydrogen bond), with external force (shear force, electric force, etc.) will be destroyed. The medium will thin out, and the viscosity drop. When the external factor disappears, the three dimensional structure (hydrogen bonds) will recover itself.



Fumed silica, one of the most valuable new inorganic material, is one. It has a small particle diameter, large specific surface area and strong surface adsorption. Its high stability, reinforcing effects, thickening and thixotropy make it an irreplaceable choice in many unique fields.
It is used widely in various industries such as additives and catalyst carriers, decolorizing agent. matting agent. rubber reinforcing. agent. plastic filling agents. ink thickening. metal soft polishing. agents. insulation and adiabatic. spraying materials. medicine. environmental protection.

Fumed silica is mainly composed of two types of "sex", hydrophilic or waterphobic. You can use chemical, mechanical, and physical methods to alter the fumed silicona interface or surface. This includes surface energy, surface wetability, reaction characteristics, surface structure, functional groups, and electrical properties. This allows it to be used in modern new materials, new technology, or for the development of new technologies.

Silica Gel MW and Its Applications

/ / no Comments

Silica gel has a wide range of applications. It is a drying agent, cooling agent, adsorbent, and separation agent. Many applications involve its use as a refractory binder.

The most common applications are in the chemical industry as a support material for chemically bonded phases. Other applications include its use in food, pharmaceuticals, and coatings. In addition, silica aerogel is used as a thickening agent in the coating industry.

Silicone gel is an inexpensive and flexible material that is colorless and transparent. A large number of applications use its nontoxic properties.

Silica particles have high mechanical strength and are compatible with water. They are available in a variety of particle sizes and pore shapes. Older silica particles are highly acidic, while newer particles are less acidic and more stable.

Newer silica particles are characterized by the presence of nonpolar silicon hydride Si-H groups, which provide improved stability at high temperatures. These groups also reduce the bleed of the organic phase.

Mesoporous silica particles have well-ordered mesoporous structures that provide better selectivity than amorphous silica samples. Additionally, mesoporous silica samples are in good agreement with N2 adsorption measurements.

Silica aerogel is used as a thickening and anti-sticking agent for plastic film. It is also a matting agent in the coating industry.

It is known to be thermally stable and has a moisture content of around 0.06kg/kg. However, it is only soluble in the vapor phase at high water vapor pressure. Unlike amine-functionalized silica, it is not able to increase its adsorption capacity.
