usage
AUTOMOTIVE REPAIR
Head gaskets often become brittle over time, which can cause leaks where they intersect with metal surfaces. Water glass seals these leaks, allowing the gaskets to perform for longer stretches of time.
FOOD AND BEVERAGES
Bathing fresh eggs with a water glass solution seals the open pores of the outer egg shell, preventing bacteria from entering. With this coating, eggs can remain fresh and unrefrigerated for months.
WASTEWATER TREATMENT
A small amount of water glass added to municipal water treatment plants or wastewater treatment plants acts as a flocculant, combining heavy metals so their weight causes them to sink to the bottom of the tank.
DRILLING
When industrial drills meet granular formations with a high permeability, it seriously dulls the drill bit. Injecting water glass and a catalyst, such as an ester, into the soil will form a polymerized gel to stabilize the soil, and increase its strength and stiffness.
OTHER USED
AS A CEMENT
Water glass is the adhesive for paper, glass, leather, and a large range of boxes, from cereal to industrial shipping cartons. It is specifically used in situations involving high heat, such as baking or in situations where contact with an open flame is common.
CERAMICS
Water glass adheres to intersecting ceramic surfaces, tightly bonding them before the entire piece is fired in a kiln. During slip preparation, water glass becomes a deflocculant, assuring an even suspension of product. The characteristic crackled pattern on many new goods is the result of a layer of water glass on the surface.
MANUFACTURING
In any industry, the ubiquitous white silica gel packets placed into packaged goods are created with more viscous water glass; its silicon-to-water ratio is much greater to create this viscosity. Their function is to control moisture inside boxes or packing crates. This ability to adhere works strikingly well to form castings. Sand grains with the addition of water glass bind so solidly they form industrial castings ready to accept molten metal within foundries.
POWDERED LAUNDRY AND DISH DETERGENTS
When water glass is combined with water, the solution is alkaline, which is ideal for removing oils and fats, breaking down proteins and starches, and neutralizing acids.
TEXTILES
A coating of water glass on many surfaces, including wood, gives a level of passive fire control to the object. For materials utilized outside, water glass acts as a barrier for passive insect control.
