Micronized silica is an industrial powder that is used in various refractory and metallurgical industries. In these industries, powdered silica is used due to the improvement of high temperature, wear resistance and oxidation resistance. Silica powder is produced in various meshes (granulation of the desired soil with the purpose of sieving), including mesh 180, mesh 230, mesh 325 with a purity level of 99%. In this article, Nejad Holding's site has been told about the production method and application of granulated silica. In the following, we will introduce you to how to buy micronized silica powder and the price of micronized silica. So stay with us

What is micronized powder

Powdered silica is actually a micron sized powder (below 20 microns). Micronized powder is obtained by grinding industrial stones such as silica, which can be used in agricultural, pharmaceutical, and construction industries. This powder is like bentonite, barite, mica and industrial talc

How is micronized silica produced

First, silica is extracted from the mine, then it is granulated and its waste materials are extracted. After that, one side is sent with strong mills to be ground. This stone goes through the granulation stage with fully automatic devices of micron sizes.Special micronized mills include

Jet mill mill (for the production of pharmaceutical and food powders)

Raymond mill (for the production of powders for mineral and metallurgical industries)

Raymond Pushrafte Mill

Separator mill

ball mill

Micronized silica powder

Types of applications of micronized powder

White micronized silica or in other colors are used in various industries and sometimes even unbelievable. These industries include

Tile and ceramic making

glazing

 Cement production

Production of casting molds

Tile adhesives

 Concrete and concrete additives

Paint and glue industries

Silica Industries

 Production of silica compounds

Fire extinguisher powder

Liquid and toothpaste

Detergents and cleaning agents such as soap

Sealants and Mel powder

and…

All the above are just a few of the uses and benefits of this amazing powder.The explanation and description of all its uses are not included in this article; Therefore, we describe two of its uses

Micronized silica in hygiene products and toothpaste

Powdered silica includes inorganic powders that are used in the manufacture of toothpastes for the purpose of cleaning and concentrating. This powder cleans the teeth from sticky substances on the tooth surface such as plaques. The granulated silica cleans the teeth without any scratching and reducing the polish of the teeth

Micronized powder is also used in the production of other detergents and cleaning materials such as all kinds of liquids. For example, abrasive soaps contain 70% silica powder. The reason for using this material in detergents is to clean different surfaces such as metal, wood and other objects. Ara Seng Alvand company is the sales reference of the highest quality of this type of powder.Micronized silica in glazing and coloring

This type of silica powder is prepared by first extracting silica from the mine, then crushing it, washing it, and magnetizing it twice. With this work, the iron in the stone comes to its lowest level. Finally, we dry the silica inside the machine and send it to the grinding machines. Micronized powder is packaged in different sizes and sold in the market

to flirt

Micronized silica has a great effect on the production of pure beverages by filtering the protein contained in it. SS-SIL is not harmful to the human body because it is highly refined and has excellent absorption powder due to the very precise and carefully controlled pores. It prevents dust from entering by controlling humidity. Application: Beverages (beer, beverage), food, edible oil.Moisture eliminator

If moisture is present in the zinc paint or alumina paint, hydrogen gas is generated and causes cracking. Micronized silica causes inhomogeneous color distribution due to moisture during storage, transportation and handling. SS-SIL has excellent absorption powder so when added to strength products, moisture is easily removed. Also not harmful to the human body, micronized silica allows for long-term preservation of food when used as a food additive. Its use: instant food, powdered food (salt, sugar), animal food

What is micronized synthetic silica

Synthetic micronized silica consists of amorphous silicon dioxide, which originates from the synthesis of minerals in the water phase, and its particle size ranges from 2 to 25 microns.Micronized synthetic silica, produced through the well-known sol-gel process and then finally manufactured by special techniques, with high porosity (pore volume from 0.4 to 2.0 cm3 / g) and moisture content in the range of 2% to 60% is specified. Other special features of this product include the following:

low apparent density

high water absorption capacity

good colorimetric values

It is usually used as an additive to plastic materials

Effective matting agent

The chemical process of making micronized silica

Silica hydrogel as the raw material of SS-SIL is carefully selected by following the mixing reaction between sodium silicate and sulfuric acid

Na2Oㆍ3.4SiO2 H2SO4 → Na2SO4 3.4SiO2

Once the silica gel is made by the above reaction, it follows the washing and drying process to obtain the desired physical properties.Then, by grinding it, make a variety of SS-SIL grades by controlling particle size and shape, interparticle cohesion, and particle filler structure. The applications of SS-SIL are not only in the film, paint, ink, paper industries, but also in the toothpaste, drug, and food industries because it is not harmful to the human body

Industries related to micronized powder

As mentioned, this element is used in various industries. The measuring unit of this powder is micron (one thousandth of a millimeter), hence it is called micronized powder and the meaning of micronized means reducing the diameter of the average size of solid objects. To measure its quality, they use criteria such as the type of stone and its grain size.This powder is a vital element in many industries such as

Paint industries

Composite

Construction and concrete industries

rubber

wire and cable

wood

PVC

Kinetics

drilling

oil

and…

The price of micronized silica

As you know what micronized silica is, this powder is on a micron scale and its granulation composition is below 20 microns. To know the price and purchase of silica powder, you can refer to Behnejad Holding Group's website as one of the manufacturers and factories of white micronized powder
