Description
Technical field
The invention belongs to water treatment field, more particularly, relate to a kind of without phosphorus compound corrosion inhibiting and descaling agent.
Background technology
China is the country of a water resources famine, has per capita water resources 2000 m that the water resources per capita of 18 provinces, municipalities and autonomous regions is reviewed lower than United Nations Commission for Sustainable Development
3, 10 provinces, municipalities and autonomous regions are lower than 1000 m
3the minimum line of existence, the wretched insufficiency of water resources will affect normal productive life, affects expanding economy, and recirculated cooling water is the rich and influential family of process water.Due to the worsening shortages of Freshwater resources, industrial colling treatment agent is more and more subject to people's attention.Organic phospho acid is a now widely used class water conditioner, and it is the exploitation of external the mid-1960s, the class water conditioner be identified the seventies, have good chemical stability, high thermal resistance and have that consumption is few concurrently, the feature such as inhibition and scale effect.In addition, organic phospho acid has excellent sequestering power to many metal ions, and they solve the problem that system produces calcium carbonate scale, and C-P key exists makes its stable chemical performance, more high temperature resistant, has obviously " threshold effect " and " synergistic effect ".Its defect is calcium phosphate scale, zinc dirt and the ferric oxide deposition problems that organic phospho acid can not suppress to produce in phosphorus system and phosphorus zinc system water treatment formula effectively, and phosphorus-containing wastewater discharge causes body eutrophication and marine red tide problem.External implemented limit phosphorus or prohibited phosphorus measure, China also advocates low-phosphorous and without the exploitation of phosphorus product energetically.Copolymer antisludging agent is a kind of New Type Water Treatment Chemicals developed after entering the eighties, good, the without phosphorus pollution of its superior performance, compatibility, development prospect are wide, but its price is high, is used alone and can not meets water treatment needs, therefore the composite rear use of other components need be added.
Through retrieval, Chinese patent application publication number CN 101560022 B, the applying date is that the patent document on May 26th, 2009 discloses a kind of composite slow-corrosion scale resistor, by organic phospho acid 15% ~ 30%, vinylformic acid or acrylic copolymer 10% ~ 20%, polymaleic acid 2% ~ 10%, azole derivative 1% ~ 3%, multi-element organic amine sulfonate 15% ~ 30%, dimethyl formamide or alcohol 2% ~ 6%, the raw material of water 20% ~ 35% quality proportioning is made, this invention composite slow-corrosion scale resistor is used for the system of middle water as recirculated cooling water, the corrosion that in can solving, water cycle water causes equipment, but the higher and complicated components of phosphorus content in this composite slow-corrosion scale resistor, be only applicable to the system of middle water as recirculated cooling water, application is restricted.Chinese patent application publication number CN 101767885 A, the applying date is that the patent document on January 12nd, 2010 discloses a kind of phosphate-free corrosion inhibition antisludging agent for water treating equipment, its active principle weight ratio is: itaconic acid-propenoic acid-Acrylate copolymer 18-20%, 2-acrylamide-2-methyl propane sulfonic acid-acrylamide polymkeric substance 8-10%, poly-epoxy succinic acid 9-11%, hydrolytic polymaleic anhydride 10-12%, fluorescein 0.5-1.5%, water 45-53%, the main ingredient of this invention is natural high moleculer eompound, there is natural cyclic structure, there is the active group of chelating high volence metal ion, there is certain corrosion and scale inhibition performance, but anticorrosion-antiscaling effect is bad and fluorescence in component have certain toxicity, injury is had to human body, the secondary pollution of water body can be caused.Therefore, in order to meet current water treatment needs, being badly in need of developing a kind of toxicity low, environment, human body and crop are safe from harm, and the corrosion inhibiting and descaling agent that corrosion-mitigation scale-inhibition efficiency is high.
Summary of the invention
1. the problem that will solve
