Abstract
A water scale remover is a composition for water treatment. It contains water-soluble organic acid (60-80 wt.%), ionic surfactant (3-6 wt.%, ammonium salt as codissolvent (8-35 wt.%) and corrosion inhibitor (2-10 wt.%). Its advantages include widely available raw materials, low cost, high effect and no poison).
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.
Make the heat exchanger of heat-eliminating medium with water, after date unavoidably can fouling when using one section, because the formation of incrustation scale will make heat transfer efficiency reduce, even cause scrapping of equipment.For addressing this problem, existing solid alkaline scale remover and liquid mineral acid scale remover appear on the market.Though the alkalescence scale remover is economical, troublesome poeration, and need specified conditions; Liquid mineral acid scale remover corrodibility is big, and storing is extremely inconvenient.It is the automatic scale removing agent for water tank of vehicle of main component preparation with the thionamic acid that CN1085525A discloses a kind of, because thionamic acid is a kind of weak acid, so descale effect has been subjected to certain limitation; It is the automobile radiator descaling cleaning agent of main component preparation with nitrilotriacetic acid, ethylenediamine tetraacetic acid (EDTA) that CN1095694A discloses a kind of, and right nitrilotriacetic acid is water insoluble, has low toxicity again, therefore also is difficult to promote.
Purpose of the present invention is to provide a kind of nontoxic, economical, the scale removing agent of features high scale-removing effect.
The principle of the invention is such.With the water-soluble organic acid is main ingredient, is equipped with ionic surface active agent, ammonium salt solubility promoter and inhibiter, mixes after crushed, packs and form.The weight percent that its raw material is formed is as follows: water-soluble organic acid 60-80%, ionic surface active agent 3-6%, ammonium salt solubility promoter 8-35%, inhibiter 2-10%.
The present invention has that raw material sources are wide, and cost is low, the characteristics of safety non-toxic.Easy to use, features high scale-removing effect, and do not influence the operation of equipment during scale removal, economical and practical, can be widely used in the domestic hygiene utensil, automobile, tractor water tank and do the scale removal of the heat exchanging apparatus of heat-eliminating medium with water.
Embodiment one: automobile, tractor water tank scale removing agent (%).
Ethylenediamine tetraacetic acid (EDTA) 40 thionamic acids 30 citric acids 10
Sodium metnylene bis-naphthalene sulfonate 5 ammonium chlorides 13 urotropines 2
Embodiment two: heat exchanging apparatus scale removing agent (%).
Ethylenediamine tetraacetic acid (EDTA) 40 thionamic acids 40 thiocarbamides 8
Sodium lauryl sulphate 4 ammonium chlorides 8
Claims (4)
