Abstract
The invention provides a scale-removal agent for a shaping sleeve water path cleaning machine. The scale-removal agent comprises the following raw materials in parts by weight: 28-40 parts of hydrolytic polymaleic anhydride, 6.5-9.5 parts of sulphamic acid, 5-40 parts of hydrochloric acid, 10-30 parts of phosphoric acid and 15-55 parts of water. According to the scale-removal agent, utilized hydrolytic polymaleic anhydride has relatively high stability and temperature tolerance, has an obvious a threshold effect when the pH value of circulating cooling water is 8.0, can be chelated with calcium ions and magnesium ions in water and has lattice distortion capacity, so that the liquidity of sludge is improved, and a scale-removal effect is achieved; by virtue of utilized sulphamic acid which is free from toxicity, the corrosion caused to equipment is lower than that caused by other inorganic acids, an oxidation layer on the metal surface can be effectively removed, hard water scale can be effectively dissolved, compounds which are extremely easily dissolved in water are generated, and the scale-removal effect is achieved; utilized hydrochloric acid is low in cost and can be used for removing the scale without heating; phosphoric acid can be used for removing the scale, and a passivation layer can be formed to play a corrosion inhibition role.
Description
Technical field
The present invention relates to mechanical means cleaning applications, be specifically related to a kind of shaping cover water route cleaning machine scale remover.
Background technology
Water base of occurring in nature all calcic, magnesium ion, Here it is usually said " hard water ", concentration is greater than 150ppm is in general severe hard water.North water quality is generally at more than 150ppm, and various watering equipment, pipeline are after use after a while, and its inside all can deposit some incrustation scales and impurity, if remove not in time, will affect the service efficiency of watering equipment, even can damage equipment.
Prior art often uses acidic scale remover, and acidic scale remover can be divided into again inorganic acids scale remover and organic acid scale remover; Inorganic acids scale remover is based on hydrochloric acid, and cost is low, scale removal speed, but has stronger corrodibility and pungency, and accumulating is inconvenient, and all has pollution and harm to human body and environment; And organic acid corrodibility is low, pungency is little, but scale removal ability is relatively weak, cost is high.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of shaping cover water route cleaning machine scale remover, can not only dissolve, remove incrustation scale, simultaneously corrosion-free to equipment, can also have germicidal action, ensures the water quality after scale removal.
In order to solve the problem, the invention provides a kind of shaping cover water route cleaning machine scale remover, described shaping cover water route cleaning machine scale remover is made up of following raw materials by weight portion:
Implement technical scheme of the present invention, there is following beneficial effect:
1, the hydrolytic polymaleic anhydride stability used in the present invention and temperature tolerance higher, also obvious threshold effect is had when recirculated cooling water pH value is 8.0, can with the calcium in water, magnesium ion sequestration have lattice distortion ability, improve the mobility of sludge, to reach descale effect.
2, the thionamic acid used in the present invention is nontoxic, less than other mineral acids to the corrosion of equipment, effectively can remove the zone of oxidation of metallic surface, effectively dissolve hard scale, and forms very easily water-soluble compound, to reach descale effect.
3, the hydrochloric acid cost used in the present invention is low, easy to use, need not carry out heating can rapidly, scale removal quickly; Phosphoric acid can scale removal, can also generate passivation layer and play corrosion inhibition.
Embodiment
Below in conjunction with embodiment, the invention will be further described.
Embodiment 1: a kind of shaping cover water route cleaning machine scale remover, described shaping cover water route cleaning machine scale remover is prepared from by its parts by weight by following raw material:
Embodiment 2: a kind of shaping cover water route cleaning machine scale remover, described shaping cover water route cleaning machine scale remover is prepared from by its parts by weight by following raw material:
Embodiment 3: a kind of shaping cover water route cleaning machine scale remover, described shaping cover water route cleaning machine scale remover is prepared from by its parts by weight by following raw material:
The above; be only the present invention's preferably embodiment, but protection scope of the present invention is not limited thereto, any people being familiar with this technology is in the technical scope disclosed by the present invention; the change that can expect easily or replacement, all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of claim.
