Properties of Instant Sodium Silicate

instant sodium silicate (sodium Metasilicate Anhydrous), chemical formula Na2SiO3, is a white amorphous powder, easily soluble in water, dissolved to form a strong alkaline solution. Its solubility increases with increasing temperature, and dissociates in water to generate sodium ions and silicate ions, which are highly corrosive and hygroscopic. Instant sodium silicate has high thermal and chemical stability, and can withstand higher temperatures and a variety of chemicals without decomposition.

Use of instant sodium silicate

instant sodium silicate is widely used in many industries, and its main uses include:

1. detergent industry: Due to its excellent decontamination ability and emulsifying effect on oils and fats, instant sodium silicate is widely used in various detergents, especially industrial detergents and household washing powders.
2. Construction industry: Instant sodium silicate can be used as a coagulant aid and waterproof agent for cement and concrete, which can improve the strength and durability of the material.
3. Paper industry: It is used as a bleaching agent for pulp and a strengthening agent for paper, which can improve the quality of paper products.
4. Textile Industry: In the process of dyeing and printing of textiles, instant sodium silicate is used as a dispersant and stabilizer of dyes, which can improve the uniformity and color fastness of dyeing.
5. Water treatment: As a strong alkaline compound, instant sodium silicate can be used as a softener and corrosion inhibitor in water treatment, effectively removing heavy metal ions and hardness components in water.

Upstream and downstream raw materials of instant sodium silicate

upstream raw materials

the main upstream raw materials of instant sodium silicate include:

1. silica sand: Silica sand is the most basic raw material in the production of instant sodium silicate. It reacts with alkaline substances to generate sodium silicate through high-temperature melting.
2. alkaline substance mainly includes sodium hydroxide (NaOH) and sodium carbonate (Na2CO3). These alkaline substances play an important role in neutralizing and promoting the reaction when reacting with silica sand.

Downstream Products

the downstream products of instant sodium silicate are mainly based on its wide range of uses and the formation of a variety of chemical products and applications, such:

1. detergents and cleaners: Used in the production of various industrial and household detergents.
2. Building Materials: Used to make high-strength cement, concrete and waterproof materials.
3. Papermaking chemicals: Used in the production of high quality paper and paper products.
4. Textile auxiliaries: Used in the production of dyes and textiles.
5. Water Treatment Chemicals: Used in the production of water treatment chemicals.

Production Process of Instant Sodium Silicate

the production process of instant sodium silicate mainly includes the following steps:

1. raw material pretreatment: Silica sand and alkaline substances such as sodium hydroxide or sodium carbonate are mixed in a certain proportion.
2. high temperature melting: The mixture is melted in a high-temperature furnace to produce liquid sodium silicate.
3. Rapid cooling: The molten sodium silicate undergoes rapid cooling to form an amorphous, instant sodium silicate solid.
4. Crushing and screening: The cooled solid sodium silicate is crushed and sieved to obtain a uniform powder product.
5. Packaging and storage: The final product is packaged and stored in a dry and sealed environment.

Storage Method of Instant Sodium Silicate

because instant sodium silicate is highly hygroscopic and corrosive, its storage method requires special attention:

1. dry environment: It should be stored in a dry environment to avoid moisture. The storage room should be well ventilated and the humidity should be checked regularly.
2. Sealed packaging: Instant sodium silicate should be stored in a sealed container or packaging bag to prevent moisture absorption and contamination. Commonly used packaging materials include plastic bags and plastic drums.
3. Anti-corrosion measures: Due to its strong alkalinity, the storage equipment should be made of corrosion-resistant materials, such as plastic or stainless steel, to prevent corrosion and damage to the equipment.
4. Avoid contact with acidic substances: Avoid contact with acidic substances, because the acid-base neutralization reaction will cause product failure and release heat, which poses safety risks.
5. Identification and safety protection: The storage area should be clearly marked and equipped with necessary safety protection equipment, such as protective gloves and goggles, to prevent safety accidents caused by personal contact.
