Abstract
A scale remover for the circulating water system of a central air conditioner is composed of the following raw materials in parts by weight: 30 to 40 parts of sulfamic acid, 20 to 30 parts of critic acid, 5 to 20 parts of ethylene diamine tetraacetic acid (EDTA), 5 to 10 parts of sodium humate, and 30 to 40 parts of purified water. The scale remover is mainly composed of mixed acids, the scales and corrosion products on the metal surface can be peeled off, soaked, dispersed, and chelated through the oxidizing performance and acidic property of acids and the active groups in the acids, thus the scales and corrosion products are washed to the washing liquid, and the metal is cleaned. The scale remover is environment-friendly and has a good performance.
Description
Technical field
The present invention relates to a kind of air-conditioning scale remover, be specifically related to a kind of scale remover for center air-condition circle water system.
Background technology
Water coolant and refrigerated water is had in central air-conditioning.Water is a kind of good heat-eliminating medium, less expensive, even if but through treated waters such as waterworkss still to some extent containing dissolved solids, gas and various suspended substance.These dissolved solidss, gas and suspended substance etc. can cause the such as problem such as settling, burn into microorganism (algae, bacterium mud) breeding, and the existence of these problems, bring harm can to the safe operation of central air-conditioning.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the object of the present invention is to provide a kind of scale remover for center air-condition circle water system, its character is relatively gentle, substantially do not produce corrosion of metal, energy safety, effective multiple settling removing metallic surface rapidly, dirty matter, because component forms through complex configuration, can supply mutually, play maximum effect.
In order to achieve the above object, the technical scheme that the present invention takes is:
For a scale remover for center air-condition circle water system, the parts by weight of its raw material are:
Thionamic acid 30 parts-40 parts
Citric acid 20 parts-30 parts
Ethylenediamine tetraacetic acid (EDTA) 5 parts-20 parts
Sodium humate 5 parts-10 parts
Pure water 20 parts-35 parts
Major ingredient of the present invention is mixing acid, Main Function mechanism be utilize itself oxidisability, acidity and the sequestering power with active group, to the strippings such as the dirty scale and corrosion product of metallic surface, infiltration, dispersion, chelating be covered in washing lotion, having reached the object of cleaning, is the scale remover of air-conditioner circulating water system of a kind of environmental protection, excellent property.
embodiment:
Below in conjunction with specific embodiment, the present invention is described in detail.
Embodiment 1
For a scale remover for center air-condition circle water system, the parts by weight of its raw material are:
Thionamic acid 34 parts
Citric acid 25 parts
Ethylenediamine tetraacetic acid (EDTA) 16 parts
Sodium humate 5 parts
Pure water 30 parts
The object of the present invention is to provide a kind of medicament for Status of air duct cleaning, its character is relatively gentle, substantially do not produce corrosion of metal, energy safety, effective multiple settling removing metallic surface rapidly, dirt matter, because component forms through complex configuration, can supply mutually, play maximum effect.
