glass is the common name of sodium silicate. With the development of
industrial technology and manufacturing technology, sodium silicate water glass
is used more and more widely. What are the characteristics of sodium
silicate water glass? What are the main applications? We will introduce to
you the details in this article.
recent years, the use of sodium silicate water glass in the coating
manufacturing process is more common, such as water glass interior wall
coating, the preparation and film-forming principle of water glass polyvinyl
alcohol water glass interior wall coating. It is to make full use of the
emulsifying effect of surfactant, mix polyvinyl alcohol and water glass under
intense agitation and highly disperse in water to form emulsion. Then add other
ingredients and mix well to make the product. When the paint is applied on the
wall, after the water is fully used, it can form a bright and clean film
containing filler and other components and playing the role of decoration and
Sodium silicate water glass is composed of
alkali metal oxide and silicon dioxide. It is a kind of metal silicate that
dissolves in water. The water glass commonly used in construction engineering
is the water solution of sodium silicate.
of sodium silicate water glass:
the bonding ability is strong. When it is hardened, precipitated silica gel can
block capillary pores and prevent water penetration.
It has good heat resistance. Although the foam alkali is not inflammable, its
strength will not be reduced under high temperature. It is used to prepare
heat-resistant concrete, heat-resistant mortar and heat-resistant mortar;
It has strong acid resistance, and the effervescence of effervescent alkali is
affected by almost all inorganic and organic acids (except hydrofluoric acid,
overheated phosphoric acid, high-grade fatty acid or oleic acid), which is used
to prepare acid resistant concrete, acid resistant mortar, acid resistant
The alkali resistance and water resistance are poor. After adding sodium
fluosilicate, the foam alkali can not be completely hardened. Because the foam
alkali is soluble in alkali and water, in order to improve the water
resistance, the hardened water glass can be treated with acid with medium
concentration of acid.
of sodium silicate water glass:
Waterproof base material: Take the aqueous solution of sodium silicate as the
waterproof base material, add two, three or four kinds of alum to prepare the
two alum, three alum or four alum fast setting waterproof agent, the setting
speed of this waterproof agent is generally no more than one minute, and use
the fast setting effect and adhesiveness to mix it into cement slurry, mortar
or concrete for repair, leakage stoppage, emergency repair and surface treatment.
Cementitious material: Water glass is a cementitious material, sodium
fluosilicate is used as a coagulant, heat-resistant or acid resistant coarse
and fine aggregate is configured in a certain proportion, the ultimate service
temperature of water glass heat-resistant concrete is below 1200 ℃, water glass
acid resistant concrete is generally used for acid storage tank, acid pickling
tank, acid resistant horizon and acid resistant equipment, etc.
The density and strength of porous materials can be improved by soaking them
with bubble alkali, which has good effect on clay brick, silicate products,
cement concrete, etc., but it can not be used to brush or impregnate gypsum
products, because sodium silicate and calcium sulfate will react to produce sodium
sulfate, crystallize in the pores of products, and the products will be damaged
by significant volume expansion.
the liquid bubble soda and calcium chloride solution are alternately injected
into the formation alternately, forming silica gel, wrapping the soil particles
and filling the pores of the formation. The silicate colloid is a kind of
freezing gel that absorbs water and expands. Because it absorbs underground
water, it is often in an expansion state to prevent the water from being
penetrated and solidifying the soil.
The liquid water glass and fire-resistant filler are mixed into paste
fire-retardant paint, which can be applied on the wood surface to resist the
instantaneous flame and reduce the ignition point.
It is very
important to choose sodium silicate water glassmanufacturer if you want to buy high
quality sodium silicate products. Sichuan
Honghao Tianfu Industry Co., Ltd is the largest sodium silicate
production base in Southwest China.
