Abstract
Non-corrosiveness scale remover, it is made up of the mass fraction of following each component, 35 45 parts of sulfamic acid, 10 18 parts of propionic acid, 67 parts of Sodium Polyacrylate, 2 10 parts of citric acid, 38 parts of phosphoric acid, 40 50 parts of polyethylene glycol, 13 parts of ammonium chloride, 13 parts of ammonium sulfate, 15 parts of rust remover, 91 99 parts of deionized water.The beneficial effects of the invention are as follows：Various incrustation scales can be conveniently removed at normal temperatures, and there is certain bactericidal action, at the same it is corrosion-free to water equipment, and meanwhile acceptable pre- antifouling formation, the number of manual cleaning boiler is reduced, reduces energy resource consumption, it is cost-effective.
Description
Technical field
The present invention relates to chemical technology field, and in particular to a kind of non-corrosiveness.
Background technology
Water in nature more or less all calcic, magnesium ion, are all " hard water ", because its concentration is different, generally
Concentration is severe hard water more than 150ppm, and northern water quality is typically in more than 150ppm, when various water equipments, pipeline pass through one section
Between use after, can all deposit some incrustation scales and impurity inside it, if removing not in time, the use effect of water equipment will be influenceed
Rate even can damage equipment.
Because boiler is during operation, many incrustation scales can be produced, these dirty presence, have sizable danger to boiler
Evil.First, fuel is wasted, reduces and contributes.Easily cause accident, influence safe operation.In addition, pipeline can be blocked, water circulation is destroyed.
Cause underdeposit corrosion, shorten boiler life.Meanwhile after gyp, time, expense and the workload cleaned and repaired will be increased
Deng influenceing to produce.Boiler effective rate of utilization is reduced, reduces economy.
In order to prevent boiler knot from scaling, ensure safe and economical boiler operation, the Water purification of boiler must be strengthened, protected
Card feed water quality meets national standard.Since the fifties, water treatment agent that China generally uses is water softener, water softener
Calcium that can only be in the precipitation boiler feedwater of part, magnesium ion, can only slow down the formation of incrustation scale, can not effectively scale inhibition.
Prior art often uses acidic scale remover, and acidic scale remover can be divided into inorganic acids scale remover again and organic acid removes
Dirty agent；For inorganic acids scale remover based on hydrochloric acid, cost is low, scale removal speed, but has stronger corrosivity and excitant, storage
Fortune is inconvenient, and has pollution and harm to human body and environment；And organic acid corrosivity is low, excitant is small, but scale removal energy
Power is relatively weak, cost is high.
The content of the invention
In order to realize above-mentioned technical purpose, the present invention provides a kind of non-corrosiveness scale remover.
Technical scheme is as follows：
Non-corrosiveness scale remover, it is made up of, sulfamic acid 35-45 parts, propionic acid 10-18 parts, gathers the mass fraction of following each component
PAA 6-7 parts, citric acid 2-10 parts, phosphoric acid 3-8 parts, polyethylene glycol 40-50 parts, ammonium chloride 1-3 parts, ammonium sulfate 1-3
Part, rust remover 1-5 parts, deionized water 91-99 parts.
Preferably, the non-corrosiveness scale remover, is made up of the mass fraction of following each component, 40 parts of sulfamic acid, third
Acid 15 parts, 6 parts of Sodium Polyacrylate, 6 parts of citric acid, 5 parts of phosphoric acid, 45 parts of polyethylene glycol, 2 parts of ammonium chloride, 2 parts of ammonium sulfate, go from
Sub- 95 parts of water, 3 parts of rust remover.
Described rust remover is triethanolamine, sub- sodium at least one.
The present invention also provides the preparation method of the non-corrosiveness scale remover, and its step is as follows：
（1）, solid material citric acid, Sodium Polyacrylate, sulfamic acid, ammonium chloride, ammonium sulfate, rust remover sequentially added into material
In kettle, then add water and stirring dissolves solid material；
（2）, by liquid material propionic acid add material kettle in and be stirred, make its dissolving；
（3）, the phosphoric acid that concentration is 85% squeezed into material kettle successively, and all materials are stirred；
（4）, by well mixed material through 200 mesh terylene screen filtrations, can obtain.
The beneficial effects of the invention are as follows：Various incrustation scales can be conveniently removed at normal temperatures, there is certain bactericidal action, together
When it is corrosion-free to water equipment, while can also pre- antifouling formation, reduce manual cleaning boiler number, reduce the energy disappear
Consumption, it is cost-effective.
