Descrição do produto
Sodium Silicate Solution - Adhesive for Cardboard, Detergent Builder, Foundry Sand Binder
Sodium silicate, commonly known as water glass or liquid glass, features the general chemical formula Na₂O*nSiO₂ and represents a family of alkali metal silicates. This versatile product typically appears as a colorless, bluish-gray, or slightly reddish viscous aqueous solution, though solid forms such as powder or lumps are also available. Its core properties include a strongly alkaline solution, excellent adhesive and film-forming capabilities, colloidal characteristics, and the ability to react with various polyvalent metal ions to form insoluble silicate gels.
As a long-established, low-cost, and versatile inorganic chemical raw material, sodium silicate serves foundational roles across multiple basic industries including paper product bonding, detergents, foundry operations, mineral processing, building material waterproofing, and chemical corrosion protection.
Core Applications and Industrial Uses
Packaging and Paper Products Industry: Sodium silicate serves as a classic inorganic adhesive in corrugated cardboard production lines, where its extremely low cost and fast setting provide sufficient initial bond strength. This makes it particularly suitable for manufacturing heavy-duty packaging boxes without high waterproofing requirements. Additional applications include bonding paper tubes and laminated paper products.
Detergent and Cleaning Industry: Functioning as a builder, buffer, and corrosion inhibitor, sodium silicate softens hard water by precipitating or dispersing calcium and magnesium ions. It maintains wash liquor alkalinity and prevents detergent corrosion on metal equipment, with particular importance in automatic dishwasher detergents and metal degreasing cleaners.
Foundry and Refractory Industry: In the CO₂ process, sodium silicate solution mixed with silica sand creates molds and cores. When gassed with carbon dioxide, a rapid chemical reaction forms a silica gel that firmly binds sand grains, achieving quick hardening suitable for single-piece or small-batch casting production. It also serves as a binder for refractory castables and insulating bricks.
Chemicals, Mining, and Building Materials: This versatile material acts as an ore flotation agent, building material waterproofing component, chemical corrosion protection additive, and textile processing auxiliary. Specific applications include formulating silicate-based sealers, soil stabilization, producing silica gel and molecular sieves, and serving as a dyeing auxiliary and fire-retardant treatment agent.
Product Specifications and Parameters
A core parameter of sodium silicate is its Modulus (M), representing the molar ratio of SiO₂ to Na₂O (M = nSiO₂ / Na₂O). The modulus significantly influences alkalinity, viscosity, adhesive properties, and reactivity, with common ranges spanning from 2.0 to 3.5. Additional important specifications include Baumé degree (°Be) or solids content, density, and viscosity. The product is supplied primarily in liquid form, with solid powder alternatives including anhydrous or pentahydrate forms.
Handling and Storage Guidelines
- Strong Alkalinity: Corrosive to skin and eyes; protective equipment is essential during handling
- Curing Characteristic: As an adhesive, its curing process is irreversible, requiring timely equipment cleaning
- Storage Conditions: Liquid products may crystallize or gel at low temperatures, necessitating temperature control. Solid products are hygroscopic and may experience caking
Our sodium silicate solution features stable modulus, accurate concentration, low impurity content, and consistent quality. We provide customized products with different moduli and concentrations to carton manufacturers, detergent producers, foundries, chemical plants, mining operations, and building material companies. For specific challenges regarding bond strength, setting speed, cleaning performance, or chemical reaction requirements, we offer professional selection advice and technical solutions.
