Abstract
A kind of antifreezer for water-bearing particles.This frostproofer is by containing C
4With interior water-soluble single-hydroxy compound, water miscible polyhydroxy compound or aliphatic monoethers, water miscible superpolymer or the non-polymer that has a hydrophilic radical at least, water-soluble organic salt or inorganic salts, surface-active substance and water are formed.It is antifreeze that this frostproofer is suitable for particulate matter, is particularly suitable for the antifreeze of aqueous clean fine coal and mixed coal.The present invention compared with prior art, freezing point is lower, be lower than-40 ℃, so the scope of application is wider.
Description
The present invention relates to a kind of frostproofer.
It is antifreeze that antifreezer for water-bearing particles is suitable for particulate matter.Be particularly suitable for the antifreeze of aqueous clean fine coal and mixed coal.
Existing antifreezer for water-bearing particles is as Chinese patent: antifreezer for water-bearing particles and compound method thereof.Number of patent application 88102661.1.This frostproofer mainly by weight percent is: 10~40% Diethylene Glycol, 10~25% ethylene glycol, 15~35% carboxamide, 30~60% water and 0.1~0.6% surface-active substance 105 are formed.The characteristics of this frostproofer are: antifreezing effect is better, and is nonflammable, safe and reliable, cost is low.But because of this frostproofer mainly is made up of polyol such as ethylene glycol and nonvolatile organism such as carboxamide.Though it also is a kind of frostproofer preferably, its freezing point still higher (40 ℃) makes range of application be subjected to certain limitation.
The purpose of this invention is to provide a kind of freezing point lower (being lower than-40 ℃), the antifreezer for water-bearing particles that range of application is wider.Constituent of the present invention has been selected water miscible monohydroxy compound.Mainly be to contain C
4With interior monohydroxy compound, as methyl alcohol, ethanol, propyl alcohol, Virahol, butanols, isopropylcarbinol etc.; Water miscible polyol or its aliphatic monoethers, poly-hydroxy alkane preferably, as: ethylene glycol, tirethylene glycol, triethylene Glycol, propylene glycol, two contract propylene glycol, glycerol, sugar etc.The mixture of ethylene glycol or ethylene glycol and polyol preferably; Water miscible, have nonvolatile organism of a hydrophilic radical at least.Growth, compound that this organism can stop ice crystal must be nonvolatile, promptly in use, enough little vapour pressure are arranged.Before freezing, do not have any material and from the aqueous solution, be evaporated.This compound has a hydrophilic radical at least, as, amido, carboxyl, carboxylate salt or ester group.This compound adopts superpolymer, as polyacrylamide, polyacrylate(s) etc., or non-polymer, as fumaric acid, sodium formiate, carboxamide, acetate, amine etc.; A kind of water-soluble organic or inorganic salt is as ammonium nitrate etc. and a kind of surface-active substance.
The present invention adopts following raw material, and by following weight percent, prepares under normal temperature, normal pressure.
Tirethylene glycol: 15~60%
Ethylene glycol: 10~40%
Ethanol: 1~25%
Carboxamide: 5~30%
Sodium-acetate (or amine): 3~20%
Water: 20~60%
Surface-active substance: 0.1~5%
Superpolymer: 0.1~5%
Inorganic salt (as ammonium nitrate): 5~20%
Boric acid: 0.1~5%
Embodiment 1:
In container, put into 20% ethanol, 12% ethylene glycol, 34.5% water, 24% carboxamide, 0.5% surface-active substance, 4% sodium-acetate, 5% boric acid, and stir.
Embodiment 2:
Tirethylene glycol with 15%, 12% ethylene glycol, 30.5% water, 15% ammonium nitrate, 24% carboxamide and 0.5% surface-active substance are put in the container, and stir.
The present invention compared with prior art has the following advantages: freezing point lower (being lower than-40 ℃), so the scope of application is wider.
