Further, the organic carboxyl acid class is poly-epoxy succinic acid (relative molecular weight 1000~1700) and hydroxyl second
Acid, hydracrylic acid, sodium gluconate, sodium tartrate, maleic acid/acrylic acid (MA/AA) copolymer, any two kinds in citric acid
Or multiple combinations.Wherein, the ratio of poly-epoxy succinic acid and other organic carboxyl acids is not less than 1:1.Poly-epoxy succinic acid is a kind of
Without phosphorus, non-nitrogen " green " environment-friendly type polybasic organic carboxylic acid, to calcium carbonate, calcium sulfate, barium sulfate, calcirm-fluoride and the silicon in water
Dirt has good scale inhibition and dispersion performance, and scale inhibition effect is better than common organic phosphine substance.It has been investigated that with other carboxylic acids
Substance compounding has good synergistic function, while poly-epoxy succinic acid has certain corrosion inhibition, is a kind of polynary
Corrosion inhibiting and descaling agent, biodegradability is good, has wide range of applications, good with other medicament compatibilities.Hydroxyacetic acid, hydroxyl third
Acid, sodium gluconate, sodium tartrate, maleic acid/acrylic acid (MA/AA) copolymer, citric acid belong to hydroxycarboxylic acid or its salt,
To calcium and magnesium ion have well it is sequestering, to insoluble metal dirt play the role of chelating removing.And it has been investigated that using
The poly-epoxy succinic acid that relative molecular weight is 1000~1700, scale inhibition and dispersion are stronger.
The amino acids do not include ethylenediamine tetra-acetic acid and its salt.Disodium ethylene diamine tetraacetate and its salt are tradition
Chelating agent, but itself biological degradability is poor, and solubility is low in process for preparation, and cleaning process needs plus 80 DEG C or more high temperature just have
Effect, therefore, present invention exclusion use this medicament as material composition.

Two or three of combination.These three amino acids substances have without phosphorus, nontoxic, nuisanceless and fully biodegradable characteristic.
There is extremely strong sequestering power to ion, there are inhibition and scale inhibition double effects, to calcium carbonate, calcium sulfate, barium sulfate, calcium phosphate etc.
Scaling salt class has good scale inhibition effect, while having peptizaiton and can effectively prevent the corrosion of metal equipment.And it passes through
The study found that using molecular weight for 1000~5000 poly-aspartate, scale inhibitor is more preferable.
The dispersing agent is the Malaysia N- acyl -2-aminoethanesulfonic acid, in acrylic acid -2- acrylamide-2-methyl propane sulfonic
Any one or two kinds.The Malaysia N- acyl -2-aminoethanesulfonic acid is using taurine and maleic acid as raw material, by amidation, epoxy
What change and anionic ring-opening polymerization obtained, it introduces sulfonic group in the molecular structure to improve dispersion performance, can greatly improve to help and wash
Performance, it may have biodegradable compensates for the disadvantage that cleaning host agent sequestering power is strong but dispersibility is poor.Acrylic acid -2-
Acrylamide-2-methyl propane sulfonic, due to containing the good carboxylic acid group of scale inhibition and dispersion performance and highly polar sulfonic acid in molecular structure
Base can improve calcium tolerance, have significant scale effect to calcium phosphate, calcium carbonate, the zinc dirt etc. in water, prevent the heavy of iron oxide
