Ethyl silicate 32%

Chemical composition of general formula (C2H5O) 2 n + 2 sinon - 1

Room temperature is colorless or light yellow transparent liquid, with similar ether smell. With ethanol, acetone and other organic solvents miscibility, hydrolysis reaction with water can generate sol silicate and gives off heat, is cloudy in the moist air, static after clarification, non-toxic.

USES:

Along with the advance of science and technology, the application of ethyl silicate series products will be more widely, especially for investment precision casting process has the following characteristics and other advantages.

1, all can make alloy casting, especially difficult machining heat resistance and high hardness of the alloy;

2, because there is no parting surface, so the casting surface quality;

3, extremely precise casting appearance size, high surface finish, thus greatly save the metal material processing cost;

4, casting can be all kinds of complicated shape of molding parts;

5, all kinds of refractory with binder;

6, is the best material to make high-grade, anti-corrosion, permanent paint.

Above all, ethyl silicate series products in modern many departments of the national economy such as aviation, instrumentation, ship, automobile, tractor, machine tools, gas, telecommunications, machinery, tools, weapons, such as manufacturing industry, favored by customers at home and abroad and technical experts fully affirmed, will be more and more widely used.



Industrial ethyl silicate (also known as ethyl silicate 32%)

Quality standard:

Appearance: colorless or light yellow transparent liquid. Specific gravity: 0.96 to 0.99

Acidity of hydrogen chloride (in %) : 0.01 or less silicon content: 32.0 to 34.0

The product is mainly used to ceramic mould precision casting the hydrolysate of adhesive, ethyl silicate itself is not adhesive, it must undergo hydrolysis become hydrolysate, is the bonding ability, therefore, the so-called ethyl silicate binder refers to the hydrolyzed ethyl silicate coating in revestment precision casting process on the meltability model of special refractories, is composed of hydrolyzed ethyl silicate and powdered refractory materials, made from.

Hydrolyzed ethyl silicate, is the reaction of ethyl silicate and water, is essentially ethoxy ethyl silicate molecules (C2H5O -) filling water molecules hydroxyl (OH) - the replacement process, specifically, the process is ethyl silicate by solvent (ethanol), and the effect of catalyst (hydrochloric acid) react with water.
