Concrete Natrium Hardener

Sodium silicate solution, also known as water glass or liquid glass, is a colorless, viscous, alkaline solution made by reacting silica sand and sodium carbonate at high temperatures. It is a water-soluble inorganic sodium salt with the general formula Na₂O·xSiO₂. The solution is known for its adhesive, binding, and film-forming properties, making it useful in various applications such as adhesives, cements, detergents, and drilling fluids. 

TECHNICAL SPECIFICATION

• Appearance  Colorless and opaque
• Density 1.36–1.47 grams per cubic centimeter, depending on composition
• pH 11–12.5 at 20°C
• Melting point 0°C
• Viscosity High, thick, and sticky, depending on concentration
• Solubility Fully soluble in water, but insoluble in alcohols and acids
• Hygroscopicity Absorbs moisture from the air

APPLICATION:: 

Industrial Applications:

• Detergents and Soaps: It acts as a binding agent and helps improve cleaning efficiency. 
• Paper and Pulp: It's used in deinking processes and as a binder. 
• Water Treatment: It functions as an iron flocculant and coagulant aid, and also helps with corrosion control and stabilization. 
• Construction: Sodium silicate is used in cements, refractory materials, and as a binder for various construction components. It also acts as a sealer, waterproofing agent, and corrosion inhibitor. 
• Foundry: It's used to create molds and cores in casting processes. 
• Adhesives: It serves as a binder in various applications, including adhesives for paper and other materials. 
• Refractory Applications: It's used in cements for high-temperature applications like stoves, furnaces, and chimneys. 
• Timber Treatment: It can preserve wood from insects and offer some flame retardant properties. 
• Soil Stabilization: It can be used to improve soil strength and load-bearing capacity. 
• Automotive Repair: It's used to seal leaks in head gaskets and engine blocks. 

Other Applications:

• Food Preservation: It's been used to preserve eggs and as a desiccant in food packaging. 
• Ceramics: It's used as a deflocculant in slip preparation and can be applied to pottery for a hardened outer layer. 
• Textiles: It's used in dyeing processes as a fixative and in textile manufacturing. 
• Art Conservation: It's used in art restoration and preservation due to its adhesive and consolidating properties. 

PRECAUTION::

Personal Protective Equipment (PPE):

• Eye Protection: Wear chemical splash goggles or a face shield to prevent eye contact.
• Hand Protection: Wear chemical-resistant gloves, such as those made of polyvinyl chloride (PVC) or rubber.
• Skin and Body Protection: Wear appropriate protective clothing to prevent skin contact.
• Respiratory Protection: Use a respirator if there's a risk of inhaling dust, fumes, gas, mist, vapors, or spray.

Handling Precautions:

• Ventilation: Use sodium silicate solution only in a well-ventilated area or outdoors.
• Avoid Contact: Do not breathe dust, mist, or vapors.
• Cleanliness: Wash thoroughly with soap and water after handling, and wash contaminated clothing before reuse.
• Emergency Response:

Eye Contact:

• Rinse cautiously with water for several minutes, remove contact lenses if present and easy to do, and continue rinsing. Seek medical advice if irritation persists.

Skin Contact:

• Gently wash with plenty of soap and water. If irritation persists, seek medical advice.

Inhalation:

• Remove person to fresh air and keep comfortable for breathing. Immediately call a poison center or doctor.

Spills:

• Soak up spills with inert solids like clay or diatomaceous earth. Transfer to a container for disposal or recovery.

Fire:

• Avoid breathing fire gases or vapors. Evacuate the area and use water spray to cool containers.

Storage:

• Store in a tightly closed container, in a dry place, and keep out of reach of children.
• Environmental Precautions:
• Do not allow spills to enter drains, sewers, or watercourses.
• If spillage enters watercourses or sewers, notify the appropriate authorities.
