Description
Technical field
The present invention relates to a kind of phosphate-free corrosion inhibition antisludging agent composition and phosphate-free corrosion inhibition antisludging agent and its application and maleic acids
Application of the copolymer of acid anhydride and allyloxy polyethoxy sulfonate in inhibition.
Background technology
Corrosion-mitigation scale-inhibition agent prescription used in China's cold water process is substantially based on phosphorus line formulation, although from performance
Substantially requirement can be reached, but phosphorus line formulation still has deficiency：Phosphorus system water treatment agent exists in use easily to be formed
The hidden danger of phosphoric acid salt crust influences heat transfer effect during water cooler longtime running；Phosphorus line formulation promotes microbial reproduction in recirculated water,
Consume substantial amounts of fungicide；The discharge of a large amount of phosphorus easily leads to the eutrophication of receiving water body.So it develops using low-phosphorous or without phosphorus
Corrosion-mitigation scale-inhibition agent prescription has great importance to cold water process.
Corrosion inhibiting and descaling agent compound prescription is mainly reflected in the scale-inhibiting properties of recirculated water on resistance calcium carbonate scale, resistance phosphorus dirt and resistance zinc

Acrylic acid (PAA), maleic acid-acrylic acid copolymer (MA-AA), hydrolysis of polymaleic anhydride (HPMA), poly-epoxy succinic acid
(PESA), the resistance calcium carbonate scale such as poly-aspartate (PASP) ability is strong, resistance phosphorus is dirty and resistance zinc dirt ability is weak；Acrylic acid-acrylic acid
Resistance calcium carbonate scale, resistance phosphorus dirt and the resistance of lipin polymer, acrylic acid and hydroxypropyl acrylate copolymer (AA-HPA, T-225) etc.
Zinc dirt ability is relatively strong；Acrylic acid-acrylic ester-co-polymer of sulfonate, acrylic acid and 2- acrylamide-2-methyl propane sulfonics are total to
The resistance such as polymers (AA-AMPS) calcium carbonate scale, resistance phosphorus dirt and resistance zinc dirt ability are strong；Allyloxy polyethoxy co-polymer of sulfonate
(AA-APES), the resistance such as acrylic acid and 3- allyloxy -2- hydroxy-propanesulfonic acids copolymers (AA-AHPSE) phosphorus dirt and resistance zinc dirt ability
By force, it is weak to hinder calcium carbonate scale ability.
In the water-soluble non-phosphorus polymer of synthesis, hydrolysis of polymaleic anhydride (HPMA), poly-epoxy succinic acid (PESA), poly- day
Winter propylhomoserin (PASP) etc. possesses certain corrosion inhibiting ability, and polyacrylic acid (PAA), maleic acid-acrylic acid copolymer (MA-AA),
Acrylic acid-acrylic ester analog copolymer, acrylic acid and hydroxypropyl acrylate copolymer (AA-HPA, T-225), acrylic acid-acrylic
Acid esters-co-polymer of sulfonate, acrylic acid and 2- acrylamide-2-methyl propane sulfonics copolymer (AA-AMPS), the poly- second of allyloxy
Oxygroup co-polymer of sulfonate (AA-APES), acrylic acid and 3- allyloxy -2- hydroxy-propanesulfonic acids copolymers (AA-AHPSE) etc. are no
Inhibition is only unable to, promotes corrosion instead.
