Description
Technical field
The invention belongs to water-treatment technology fields, and in particular to a kind of environmentally protective dirt dispersion agent.
Background technique
As water source of fresh water is increasingly in short supply, pollution of waterhead is got worse, as the water inlet water source of industrial water system, in water
Salt content constantly increases, and hardness, basicity are continuously improved, so that requiring the condition of water quality of processing more and more severe.Currently, in the market
Water treatment agent is mainly based on phosphorus system, and in terms of long term growth trend, the production and application of phosphorus system Scale Inhibitors for Water are restricted,
Following antisludging agent will develop towards environmental type direction.Using without phosphorus formula organic polymer mitigation and antiscaling technology therefore just by
It is gradually widely promoted, excellent scale-inhibiting properties have obtained good embodiment in the processing of severe water quality.Although
There are many environmentally friendly water treatment agents, but because of its complex manufacturing technology, equipment requirement is high, causes price higher, Wu Fashi
Now good economic benefit, can not large-scale promotion application on the market.
Poly-aspartate has excellent scale inhibition and dispersion performance, can inhibit CaCO3, CaSO4And BaSO4The formation of dirt, is resistant to
High temperature, thermal stability is good, can be applied to high temperature, high calcium water system and reverse osmosis membrane treatment system.The protrusion of poly-aspartate is excellent
Point is it from raw material, production to final products to environment Nonpoisonous, non-environmental-pollution, and has biological degradability, will not be caused to environment
Secondary pollution is the renewal product of generally acknowledged at present green polymer and water treatment product.But because its production cost is higher
Affect its large-scale popularization and application.
