Sodium silicate Mod 2 dissolves in water to produce alkaline solutions. 

Its solution is alkaline. 
Sodium silicate Mod 2s viscosity increases in proportion to the amount of substance in the solution. 
Three moduls with three molecules of SiO2 in its composition are called TWO MODULES with two molecules of SiO2. 

There is one molecule of Na2O in both silicates.
Sodium silicate Mod 2 is a generic name for chemical compounds with the formula Na2xSiyO2y+x or (Na2O)x·(SiO2)y, such as sodium metasilicate NaSiO3, sodium orthosilicate Na4SiO4, and sodium pyrosilicate Na6Si2O7.

-Sodium silicate Mod 2 is a component of inorganic coatings and a raw material for silicon series products such as silica gel, molecular sieve, and precipitated silica.

 

CHARACTERISTICS:

A fine, white powder, powdery instant Sodium silicate Mod 2 has the same ratio as liquid silicates. 
When  dissolved, Sodium silicate Mod 2 forms a hazy, colorless colloidal solution.

 

PROPERTIES:

Sodium silicate Mod 2 is colorless glassy or crystalline solids, or white powders. 
Except for the most silicon-rich ones, they are readily soluble in water, producing alkaline solutions.
Sodium silicate Mod 2 is stable in neutral and alkaline solutions. 

In acidic solutions, the silicate ions react with hydrogen ions to form silicic acids, which tend to decompose into hydrated silicon dioxide gel. 
Heated to drive off the water, the result is a hard translucent substance called silica gel, widely used as a desiccant. 
Sodium silicate Mod 2 can withstand temperatures up to 1100 °C.

 

USES:

-Adhesive:

The largest application of Sodium silicate Mod 2 solutions is a cement for producing cardboard.
When used as a paper cement, the tendency is for the Sodium silicate Mod 2 joint eventually to crack within a few years, at which point it no longer holds the paper surfaces cemented together.
Sodium silicate Mod 2 solutions can also be used as a spin-on adhesive layer to bond glass to glass or silicon oxide covered silicon wafers to one another.

Sodium silicate Mod 2 glass-to-glass bonding has the advantage that it is a low temperature bonding technique, as opposed to fusion bonding.
Sodium silicate Mod 2 is also less processing intensive than glass-to-glass anodic bonding, which requires an intermediate layer such as SiN to act as a diffusion barrier for sodium ions.
Deposition of such a layer requires a low pressure chemical vapor deposition step.

A disadvantage of Sodium silicate Mod 2 bonding, however, is that it is very difficult to eliminate air bubbles.
This is due in part because this bonding technique doesn't require bonding in vacuum and it also doesn't use field assistance like in anodic bonding.
Though this lack of field assistance can sometimes be beneficial, because field assistance can provide such high attraction between wafers as to bend a thinner wafer and collapse onto the nano luidic cavity or MEMS elements.


-Drilling fluids:

Sodium silicate Mod 2 is frequently used in drilling fluids to stabilize borehole walls and to avoid the collapse of bore walls. 
Sodium silicate Mod 2 is particularly useful when drill holes pass through argillaceous formations containing swelling clay minerals such as smectite or montmorillonite.


-Concrete and general masonry treatment:

Concrete treated with a Sodium silicate Mod 2 solution helps to reduce porosity in most masonry products such as concrete, stucco, and plasters. 
This effect aids in reducing water penetration, but has no known effect on reducing water vapor transmission and emission.
A chemical reaction occurs with the excess Ca(OH)2 (portlandite) present in the concrete that permanently binds the silicates with the surface, making them far more durable and water repellent. 

This treatment generally is applied only after the initial cure has taken place. 
These coatings are known as silicate mineral paint. 


Na2SiO3 + y H2O + x Ca(OH)2 → x CaO.SiO2.y H2O + 2NaOH


-Detergent auxiliaries:

Sodium silicate Mod 2 is used in detergent auxiliaries such as complex sodium disilicate and modified sodium disilicate. 
The detergent granules gain their ruggedness from a coating of silicates.


-Water treatment:

Sodium silicate Mod 2 is used as an alum coagulant and an iron flocculant in wastewater treatment plants. 
Sodium silicate Mod 2 binds to colloidal molecules, creating larger aggregates that sink to the bottom of the water column. 
The microscopic negatively charged particles suspended in water interact with Sodium silicate Mod 2. 

Their electrical double layer collapses due to the increase of ionic strength caused by the addition of Sodium silicate Mod 2 (doubly negatively charged anion accompanied by two sodium cations) and they subsequently aggregate. 
This process is called coagulation.


-Refractory use:

Water glass is a useful binder of solids, such as vermiculite and perlite. 
When blended with the aforementioned lightweight aggregates, water glass can be used to make hard, high-temperature insulation boards used for refractories, passive fire protection and high temperature insulations, such as moulded pipe insulation applications. 
When mixed with finely divided mineral powders, such as vermiculite dust (which is common scrap from the exfoliation process), one can produce high temperature adhesives. 


-Dye auxiliary:

Sodium silicate Mod 2 solution is used as a fixative for hand dyeing with reactive dyes that require a high pH to react with the textile fiber. 
After the dye is applied to a cellulose-based fabric, such as cotton or rayon, or onto silk, it is allowed to dry, after which the Sodium silicate Mod 2 is painted on to the dyed fabric, covered with plastic to retain moisture, and left to react for an hour at room temperature.


-Metal repair:

Sodium silicate Mod 2 is used, along with magnesium silicate, in muffler repair and fitting paste. 
When dissolved in water, both Sodium silicate Mod 2 and magnesium silicate form a thick paste that is easy to apply. 
When the exhaust system of an internal combustion engine heats up to its operating temperature, the heat drives out all of the excess water from the paste. 
The silicate compounds that are left over have glass-like properties, making a temporary, brittle repair.


-Automotive repair:

Sodium silicate Mod 2 is also used currently as an exhaust system joint and crack sealer for repairing mufflers, resonators, tailpipes, and other exhaust components, with and without fiberglass reinforcing tapes. 
In this application, the Sodium silicate Mod 2 (60–70%) is typically mixed with kaolin (40-30%), an aluminium silicate mineral, to make the Sodium silicate Mod 2 "glued" joint opaque. 
The Sodium silicate Mod 2, however, is the high-temperature adhesive; the kaolin serves simply as a compatible high-temperature coloring agent. 

Some of these repair compounds also contain glass fibres to enhance their gap-filling abilities and reduce brittleness.
Sodium silicate Mod 2 can be used to fill gaps within the head gasket. 
Commonly used on aluminum alloy cylinder heads, which are sensitive to thermally induced surface deflection. 

This can be caused by many things including head-bolt stretching, deficient coolant delivery, high cylinder head pressure, overheating, etc.
A Sodium silicate Mod 2 repair can last two years or longer. 
The repair occurs rapidly, and symptoms disappear instantly. 

This repair works only when the Sodium silicate Mod 2 reaches its "conversion" temperature at 100–105 °C. 
Contamination of engine oil is a serious possibility in situations in which a coolant-to-oil leak is present. 

Sodium silicate Mod 2 (glass particulate) contamination of lubricants is detrimental to their function.
Sodium silicate Mod 2 solution is used to inexpensively, quickly, and permanently disable automobile engines. 


-Safe construction:

A mixture of Sodium silicate Mod 2 and sawdust has been used in between the double skin of certain safes. 
This not only makes them more fire resistant, but also makes cutting them open with an oxyacetylene torch extremely difficult due to the smoke emitted.


Crystal gardens:

When crystals of a number of metallic salts are dropped into a solution of water glass, simple or branching stalagmites of coloured metal silicates are formed. 
This phenomenon has been used by manufacturers of toys and chemistry sets to provide instructive enjoyment to many generations of children from the early 20th century until the present. 
Metal salts used included the sulfates and/or chlorides of copper, cobalt, iron, nickel, and manganese.


Pottery:

Sodium silicate Mod 2 is used as a deflocculant in casting slips helping reduce viscosity and the need for large amounts of water to liquidize the clay body. 
Sodium silicate Mod 2 is also used to create a crackle effect in pottery, usually wheel-thrown. 
A vase or bottle is thrown on the wheel, fairly narrow and with thick walls. 

Sodium silicate Mod 2 is brushed on a section of the piece. 
After 5 minutes, the wall of the piece is stretched outward with a rib or hand. 

The result is a wrinkled or cracked look.
Sodium silicate Mod 2 is also the main agent in "magic water", which is used when joining clay pieces, especially if the moisture level of the two differs.


-Cosmetics:

Sodium silicate Mod 2 and other silicates are the primary components in "instant" wrinkle remover creams, which temporarily tighten the skin to minimize the appearance of wrinkles & under-eye bags. 
These creams, when applied as a thin film and allowed to dry for a few minutes, can present dramatic results. 
This effect is not permanent, lasting from a few minutes up to a couple of hours. 
Sodium silicate Mod 2 works like water cement, once the muscle starts to move, it cracks and leaves white residues on the skin.


-Homebrewing:

Sodium silicate Mod 2 flocculant properties are also used to clarify wine and beer by precipitating colloidal particles. 
As a clearing agent, though, Sodium silicate Mod 2 is sometimes confused with isinglass which is prepared from collagen extracted from the dried swim bladders of sturgeon and other fishes. 

-Aquaculture:

Sodium silicate Mod 2 gel is also used as a substrate for algal growth in aquaculture hatcheries.
