- Inorganic silicone is a highly active adsorbent material, usually reacted with sodium sulfate and sulfuric acid. Silica gel is an amorphous substance with the chemical molecular formula mSiO2.nH2O. Insoluble in water and any solvent, it is non-toxic and odorless, has stable chemical properties, and does not react with any substance except for strong alkali and hydrofluoric acid.
- Different types of silicone gel form different microporous structure due to their different manufacturing methods. The chemical composition and physical structure of silica gel determines many other similar materials: high adsorption performance, good thermal stability, stable chemical properties, high mechanical strength, domestic desiccant,humidity regulator,deodorant,etc. industrial use as hydrocarbon remover, catalyst carrier, pressure adsorbent, fine chemical separation purification agent, beer stabilizer, paint thickener, toothpaste friction agent, light inhibitor, etc.
- According to the size of its aperture, silica gel is divided into large hole silica gel, coarse hole silica gel, B type silica gel and fine hole silica gel. coarse porous silica gel has high adsorption amount with high relatively high humidity, while fine porous silica gel absorbs higher orders than coarse porous silica gel with low relatively high humidity, while type B silica gel, because the pore structure is between coarse and fine holes, and its adsorption amount is also between coarse and fine holes.
- According to its use, inorganic silicone can also be divided into beer silicone, pressure-changing adsorbent silicone, medical silicone, discoloration silicone, silicone desiccant, silicone opening agent, toothpaste silicone, etc.
- Fine-porous Silica Gel
- Fine porous silica gel is colorless or slightly yellow transparent glass, also known as A gel.
- Application: suitable for dry, moisture proof and rust proof. Can prevent instruments, instruments, weapons, ammunition, electrical equipment, drugs, food, textiles and other packaging items from getting damp, and can also be used as catalyst carriers and dehydration and refining of organic compounds. Because of high accumulation density and low humidity, it can be used as an desiccant to control air humidity. It is also widely used on the way of sea, because the goods are often damaged by moisture, and the product can be effectively dewet and damp, so that the quality of the goods is guaranteed. Fine-porous silicone is also commonly used to dehumidify between two layers of parallel sealing window panels and can maintain the brightness of two layers of glass.
- B Type Silica Gel
- Type B Silica Gel is milky transparent or translucent spherical or block particles.
- Application: mainly used as air humidity regulator, catalyst and carrier, pet cushion material, and as a raw material for fine chemical products such as silica chromatography.
- Coarse Hole Silica Gel
- Coarse porous silica gel, also known as C type silica, is a kind of silica gel, is a highly active adsorbent material, an amorphous material, its chemical molecular formula is mSiO2 · nH2O. Insoluble in water and any solvent, it is non-toxic and odorless, has stable chemical properties, and does not react with any substance except for strong alkali and hydrofluoric acid. The chemical composition and physical structure of coarse porous silica gel determine that it has many other similar materials difficult to replace: high adsorption performance, good thermal stability, stable chemical properties and high mechanical strength.
- Application: coarse porous silica gel is white, block, spherical and micro spherical products.coarse hole spherical silica gel is mainly used for gas purifying ant, desiccant and insulating oil; coarse-hole bulk silica gel is mainly used for catalyst carrier, desiccant, gas and liquid purifying ant, etc.
- Indicating Silica Gel
- Indicating Silica Gel has 2 colors.Blue and orange.
- Application: When using it as a desiccant, it is blue/orange before water absorption, and after turning red/green after water absorption, which can be seen from the change of color, and whether regeneration treatment is needed. Silica Gel is also widely used in vapor recovery, oil refining and catalyst preparation. Silica Gel can also be used to make a mobile phone shell, with an extremely high anti-fall sex.
- Silica alumina gel
- stable chemical properties, noncombustion and insoluble in any solvent. Fine porous silica aluminum gel and fine porous silica gel compare to low humidity adsorption volume (such as 10% of RH =, RH=20%), but high humidity adsorption volume (such as RH=80%, RH=90%) is 6-10% higher than fine porous silica gel, use: thermal stability is higher than fine porous silica gel (200 ℃), very suitable for temperature adsorption and separation agent.
