Abstract
The invention relates to an environment-friendly sulfate scale cleaning agent, and belongs to the technical field of water treatment. The environment-friendly sulfate scale cleaning agent is prepared from the following raw materials in percentage by weight: 1 to 5 percent of disodium ethylene diamine tetraacetate, 10 to 20 percent of citric acid, 0 to 1 percent of surface active agents, 20 to 40 percent of poly(acrylic acid-co-hydroxypropyl acrylate) polymers and 20 to 40 percent of poly(acrylic acid-co-2-acrylamido-2-methylpropane sulfonic acid) polymers, and the balance de-ionized water. The environment-friendly sulfate scale cleaning agent can be used for thoroughly clearing sulfate scale in the system; the corrosion speed on materials such as carbon steel, copper and stainless steel is low; the cleaning process is simple; no phosphorus is contained in the formula; no pollution is caused on the environment after the neutralization.
Description
Technical field
The present invention relates to a kind of environment-friendly sulfate scale washing agent, belong to water-treatment technology field.
Background technology
In industrial production, often can run into equipment scaling problem, common composition of scale have carbonate, sulfate, silicate,Phosphate etc., outside removing sulfate, generally can remove by the method for pickling or alkali cleaning, and sulfate scale are difficult in these incrustation scalesAdopt general pickling or alkali cleaning to remove, conventionally use the special mechanical descaling such as instrument or equipment, this mechanical descaling method is difficult toExcept clean, and larger to equipment damage.
CN101705159A discloses a kind of " cleaning agent ", and cleaning agent is by organic carboxyl acid, Surfactant OP-10, infiltration JFCForm with water.
CN101913713A discloses a kind of " a kind of sulfate scale cleaning agent ", and this cleaning agent is by organic carboxylate, organic phospho acidSalt, reducing agent, surfactant and water composition; CN103806009A discloses a kind of " a kind of neutral sulfatase cleaning agent ",This cleaning agent is made up of organic phospho acid, chemical cosolvent, non-ionic surface active agent, tone pitch agent, reducing agent and water. These twoCleaning agent in patent all contains organic phosphine, after later stage discharge, can make environment waters eutrophication, and environment is damaged.
Summary of the invention
The object of this invention is to provide a kind of environment-friendly sulfate scale washing agent, it is the sulfate scale in scavenge system thoroughly, andAnd the corrosion rate to materials such as carbon steel, copper, stainless steels is smaller, and cleaning is simple, and not phosphorous in formula, neutralizationRear environmentally safe.
Described environment-friendly sulfate scale washing agent, made by the raw material of following weight percentage: disodium ethylene diamine tetraacetate 1～5%,Citric acid 10～20%, surfactant 0～1%, acrylic acid hydroxypropyl acrylate copolymer 20～40%, acrylic acid 2-acryloylAmine-2-methyl propane sulfonic acid copolymer 20～40%, surplus is deionized water.
Preferably, made by the raw material of following weight percentage: disodium ethylene diamine tetraacetate 1～5%, citric acid 15～20%,Surfactant 0～1%, acrylic acid hydroxypropyl acrylate copolymer 1 5～40%, acrylic acid 2-acrylamide-2-methyl propane sulfonic is altogetherPolymers 30～40%, surplus is deionized water.
Described disodium ethylene diamine tetraacetate is the disodium EDTA that contains two molecular crystalline water.
Described citric acid is Citric Acid Mono or anhydrous citric acid.
Described surfactant is neopelex or dodecyl sodium sulfate.
Described acrylic acid hydroxypropyl acrylate copolymer and acrylic acid 2-acrylamide-2-methyl propane sulfonic copolymer are carboxylic acidsBipolymer, good to sulfate solute effect, dissolution time is short; Disodium ethylene diamine tetraacetate is to the bivalent metal ion in waterSequestering power is more intense, can increase the solubility of sulfate in water by its chelation; Citric acid is a kind of tricarboxylic acidsCompound, is mainly clean metal surface, solubilized iron oxide and cupric oxide; Described surfactant is a kind of anionic surfaceActivating agent, has the effect of excellent infiltration, washing, wetting, decontamination, can obviously increase the cleaning performance of cleaning agent.
Compared with prior art, the present invention has following beneficial effect:
(1) in formula, do not contain strong acid, smaller to equipment corrosion speed;
(2) not phosphorous in formula, environmentally safe;
(3) polymer in formula is bipolymer, removes sulfate scale speed fast;
(4) cost is low, and preparing process is simple, cleans and can carry out at normal temperatures.
