Abstract
A solid composition as scale-removing agent for water tank contains water-soluble strong organic acid, acidic solution as corrosion retardant, ammonium salt as dissolving agent and inorganic sodium salt as hydroscopic agent, and features stable performance, high effect, quick taking its effect, low corrosion to metal, no poison and odour and no need of stopping work. It can also be used for industrial boilers and cooling apparatuses.
Description
The present invention relates to a kind of composition of water treatment, is a kind of solid composition as scale remover that adds scale removal in the entry specifically.
Equipment, container that boiler and some are made cooling fluid with water are in use over a long time, and its container inner wall can form the dirt that bed thickness does not wait, and this not only influences the transmission of heat, and the reduction working efficiency also easily causes burst accident, jeopardizes equipment and personnel safety.For addressing this problem, early existing alkaline scale preventing and removing agent and liquid acidic scale remover appear on the market and use.The alkalescence scale remover scale removal time is long, and work efficiency is low, and influence is produced; Though the scale removal of liquid acidic scale remover is rapid, transportation is inconvenient, and is also bigger to the corrosion of metal vessel.CN1130599A discloses a kind of slightly acidic scale cleaning agent, is made up of organic acid, ammonium salt, sodium-chlor, nonionogenic tenside, and cost is low, and is economical and practical, the caking but product easily gets damp, and processing and use are all inconvenient.
Purpose of the present invention is to provide a kind of stable in properties, economical and practical solid composition as scale remover for cistern.
Principle of the present invention is as follows.Adding acidic solution inhibiter, ammonium salt solubility promoter and inorganic sodium hygroscopic agent with water-soluble strong organic acid combines.After strong organic acid was water-soluble, calcium, the water-soluble organic acid salt of magnesium salts reaction generation with in the dirt discharged with dirt again, thereby reached the purpose of scale removal.
It is as follows that the raw material of solid composition as scale remover is formed weight percent: strong organic acid 40～80%, inhibiter 2～8%, ammonium salt 10～20%, inorganic sodium 20～35%.
The present invention has stable in properties, and is economical and practical, the characteristics of convenient transportation.Its scale removal ability is suitable with the liquid acidic scale remover, and scale removal is rapid; Corrodibility is little, to the basic not damaged of metal vessel; Nontoxic odorless, safe in utilization, especially when cleaning water tank, need not shut down, get final product automatic desludging behind the adding product.Be applicable to the cleaning and the scale removal of Industrial Boiler and various water cooling equipments, also can be used for the cleaning of toilet utensil.
The step that the present invention is used to clean radiator is: take by weighing thionamic acid 1.2Kg, ammonium chloride 0.3Kg, urotropine 0.1Kg, Sodium sulfate anhydrous.min(99) 0.4Kg, mix behind the porphyrize respectively, add in the radiator of normal operation then, after 8 hours, put and defecate washing lotion, inject new water coolant, promptly accuse cleaning and finish.
