  • Solid Sodium Silicate Modulus 3.1-3.3

    Solid Sodium Silicate Modulus 3.1-3.3

    What is Solid Sodium Silicate?

     

    Solid sodium silicate, also known as solid water glass, is an inorganic silicate compound with the chemical general formula Na₂O·nSiO₂.

    It is produced by melting quartz sand (SiO₂) and soda ash (Na₂CO₃) at high temperature, then cooling and crushing into solid lumps, flakes or granules.

    Sanlee Chemical as a professional sodium silicate manufacturer and reliable sodium silicate solid supplier, we provide high-purity industrial sodium silicate with stable performance, especially the customized solid sodium silicate modulus 3.1-3.3 that meets diverse industrial production needs.

    The appearance of solid sodium silicate is transparent/translucent glassy solid, colorless, light gray or pale green; hard and brittle. It is not soluble in cold water, but slowly dissolves/hydrolyzes in hot water to form liquid sodium silicate solution (liquid water glass) 

     

    Introduction to Sodium Silicate Solid

     

    Solid sodium silicate, widely known as solid water glass, is a versatile inorganic silicate compound with the general chemical formula Na₂O·nSiO₂.

    It is industrially manufactured by fusing high-purity quartz sand and soda ash at extreme temperatures ranging from 1200℃ to 1400℃, followed by rapid cooling and crushing into hard, brittle, glassy solid lumps or flakes. This anhydrous solid product features adjustable modulus, referring to the variable ratio of silicon dioxide to sodium oxide, which directly dictates its physical and chemical performances for diverse industrial scenarios.

    Visually, it appears colorless, translucent or pale gray with stable solid-state properties, boasting longer shelf life and higher concentration compared to liquid sodium silicate. It is insoluble in cold water, ethanol and acidic solutions, but can gradually dissolve and hydrolyze in hot water to form homogeneous alkaline silicate solutions.

    Possessing excellent adhesion, heat resistance, acid resistance and fire-retardant properties, solid sodium silicate serves as a fundamental industrial chemical.

    It is extensively applied as a high-strength binder for foundry sand molds and refractory materials, a sealing and waterproof agent for concrete construction, and a key raw material for producing liquid water glass, ceramic glazes and industrial detergents. Its stable performance and cost-effectiveness make it an indispensable material in construction, metallurgy, chemical and environmental protection industries.

    Sodium Silicate Powder

    What is instant sodium silicate powder ?

     

    Instant sodium silicate (CAS 1344-09-8) is a white or light gray powder with good fluidity and strong moisture absorption (strict prevention is required)tide, quickly dissolved in cold or warm water (for seconds to minutes), does not require heating, forming a transparent or slightly turbid alkaline solution, with a pH value of up to 12-13 in aqueous solution. Instant sodium silicate (CAS 1344-09-8) has become an important raw material in industrial and daily chemicals due to its rapid dissolution, low cost, and multi scenario applicability.

    Instant sodium silicate powder modulus 3.1-3.3 is a high-modulus, fast-dissolving inorganic silicate powder, upgraded and refined based on conventional sodium silicate products. As a high-purity powdered water glass with a high silica-to-sodium oxide molar ratio, it fills the market gap of medium and high-modulus instant sodium silicate and is widely applied in high-demand industrial scenarios that require strong bonding, high temperature resistance and stable chemical activity.

    Although there are limitations in terms of temperature resistance and long-term stability, its widespread application in areas such as washing, construction, and environmental protection highlights its irreplaceability. Future development directions may include improving moisture-proof packaging technology, developing composite modified products (such as combining with organosilicon),and expanding innovative applications in new energy materials (such as battery binders).

     

    Introduction to Sodium Silicate Powder

     

    Modulus refers to the molar ratio of silica to sodium oxide in sodium silicate, which determines the core performance of the product.

    Different from conventional low-modulus (2.2-2.4) sodium silicate, instant sodium silicate powder with 3.1-3.3 high modulus has a higher silica content, stronger molecular stability and superior physical and chemical properties.

    The product is a uniform white sodium silicate powder at normal temperature, with no agglomeration, and can be rapidly and completely dissolved in room-temperature water without heating, leaving no insoluble residues.

    This high-modulus instant powder effectively overcomes the shortcomings of liquid sodium silicate such as short storage life, high transportation cost and low concentration.

    It integrates the advantages of instant solubility, high strength bonding, high temperature resistance, corrosion resistance and excellent pH buffering performance. Compared with ordinary sodium silicate powder, it has stronger gelation ability, higher hardness after curing and better chemical stability, making it irreplaceable in high-end industrial fields.

     

    The core advantages and features of  instant sodium silicate powder(CAS 1344-09-8)

     

    1.Sodium silicate powder has rapid dissolving properties:

    The powder of sodium silicate has a loose structure and can rapidly disperse and dissolve in water. This significantly shortens the preparation time during the production process, improves the production efficiency and continuity of downstream products, and is particularly suitable for automated feeding.

    2.High purity and precise measurement of sodium silicate powder:

    The solid content of the sodium silicate powder is close to 100%, with no excess moisture and low impurity content. This ensures the accuracy and stability of the downstream product formula, avoiding quality issues caused by impurities, and the consistency among product batches is good.

    3.The economy and convenience of powdered sodium silicate:

    Sodium silicate powder in solid form. This saves a huge amount of costs for liquid packaging and transportation, reduces storage space, and makes long-distance transportation and storage economically feasible.

    4.Sodium silicate powder exhibits excellent alkaline buffering and emulsification-dispersing capabilities:

    Sodium silicate powder provides a stable alkaline environment and has excellent emulsifying and dispersing properties. It can effectively remove dirt during washing and disperse impurities and stabilize the system in industry. It is an efficient multi-functional additive.

     

    Guide for the Use of  sodium silicate powder

     

    1.Dissolution instructions: Under stirring conditions, slowly add the powder to water to quickly form a uniform solution. It is recommended to prepare a solution with a concentration of 30% – 50% for future use.

    2.Storage conditions: The product must be stored in a cool, dry and well-ventilated warehouse to prevent it from absorbing moisture and forming lumps.

    3.Compatibility: It has a good synergistic effect with various anionic, non-ionic surfactants, sodium carbonate, STPP and other inorganic additives.
