Abstract
The invention discloses a compound synergic water treating agent, which is characterized by comprising polyepoxysuccinic acid salt, diethylene triamine pentacetic acid sodium, a copolymer of acrylic acid and maleic acid, and a copolymer of acrylic acid and 2-acrylamide-2-methylpro panesulfonic acid. When the content of the diethylene triamine pentacetic acid sodium in the composition is between 0.5 and 1, the water treating agent has jumping positive promotion effects particularly on the corrosion and scale inhibition effect on the water with high hardness and high alkalinity.
Description
Technical field
The present invention relates to a kind of water conditioner, relate to the composite water conditioner that contains polyepoxysuccinic acid salt furtherly.
Background technology
Poly-epoxy succinic acid (PESA) is the new generation of green environmental protection water treatment agent of a kind of nineties of exploitation, is a kind of have without phosphorus, non-nitrogen and good green scale inhibitor of biological degradability, and its scale inhibition effect obviously is better than the organic phosphine acids Scale inhibitors used always.Lime carbonate, calcium sulfate, barium sulfate, Calcium Fluoride (Fluorspan) and silicon dirt in the poly-epoxy succinic salt pair water have good scale inhibition and dispersion performance, and scale inhibition effect is better than organic phosphates Scale inhibitors commonly used.Polyepoxy sodium succinate and phosphonate be composite to have good synergistic function.Polyepoxy sodium succinate has certain corrosion inhibition simultaneously, and biodegradability is good, is applicable to the recirculating cooling water system of industries such as iron and steel, petrochemical industry, electric power, medicine.
The disclosed composite scale-inhibiting corrosion inhibitor that contains poly-epoxy succinic acid of CN1616361A, comprise two kinds of organic phospho acids, poly-epoxy succinic acid and acrylic copolymers and look particular case and the zinc salt and the copper material corrosion inhibitor that exist, this agent is applicable to that recirculated cooling water handles, and can make the calcium of recirculated water add basicity firmly and reach 1200mg/L.
The disclosed recirculated cooling water of CN1850661A is handled the green environment-protective composite slow-corrosion scale resistor of usefulness, by polyepoxy sodium succinate, dirt dispersion agent such as poly (sodium aspartate), hydrolytic polymaleic anhydride, Sunmorl N 60S, zinc salt and inhibiter are 1～6: 1～4 in mass ratio: 2～6: 1～2: 1～2 ratio is composite to form, environmentally friendly stable.
The disclosed a kind of corrosion-and scaling-inhibiting water treating agent of CN1435384A, it is characterized in that composition and content thereof (is 100 in the weight sum): the poly-epoxy carboxylic-acid that liquid dielectric hydrophobic substance 20-50%, oil-soluble inhibitor 20-40%, water soluble dispersing agent 1-10%, composite sensitization emulsifying agent 15-40%, excess water, described water soluble dispersing agent comprise polyacrylic acid, sodium polyacrylate, polymaleic acid, poly aspartic acid, comprise the silicate of water glass and comprise poly-epoxy succinic acid.
CN1609020A discloses a kind of water treatment method, the corrosion-proofing and antisludging method that independent use poly-epoxy succinic acid or poly-epoxy succinic acid and glyconic acid or gluconate (A component) and zinc salt are used, said poly-epoxy succinic acid molecular weight is 400～1000, consumption is 90～120mg/L, the consumption of poly-epoxy succinic acid is at 30～50mg/L, the consumption of A component is 5～8mg/L, the zinc salt consumption is at 5～8mg/L, and poly-epoxy succinic acid: A component: the mass ratio of zinc salt is 1: 0.16～0.26: 0.16～0.26.
The disclosed Phosphateless environmentally friendly corrosion inhibiting and descaling agent of CN101062816A is a kind of sulfanilic acid class poly-epoxy succinic acid or salt without phosphorus a dose; this without phosphorus dose scale-inhibiting properties that has excellence for lime carbonate, calcium sulfate, barium sulfate and strontium sulfate scale; especially calcium there is good tolerance, simultaneously corrosion of Carbon Steel is played good inhibition effect.Said without phosphorus dose has general formula and be: said without phosphorus dose has general formula and is:
