System, there is certain risk, and is unsuitable for the household heating system of various metals material composition, is easy to cause in the process of cleaning
Corrosion；In addition, acid, alkali cleaning operation complex procedures, need to be neutralized, then be passivated, make equipment cleaning time after cleaning
It is elongated, influence the normal operation of equipment.Remaining acid ion can accelerate the anticaustic of metal parts and pipeline.
201410122488.5 a kind of cleaning agent of household heating system for being made of various metals material is disclosed,
With preferable descaling rate and rate of corrosion, phosphorous ethylene diamine tetra methylene phosphonic acid sodium is then used in system, after cleaning
Cleaning solution can not carry out in line, bring great inconvenience to the wastewater treatment after family cleaning.
201710412506.7 a kind of heating system eliminating sludge in pipe agent is disclosed, although solving phosphorous Deng pollution problems,
Then manganese sulfate is used in system, is sucked the product dust for a long time in process of production, can be caused Chronic Mn Poisoning, with neurasthenia
Based on syndrome and neurological dysfunction, and it is harmful to environment, water body can be polluted.And preparation process is complicated, to life
It makes troubles production side.
Therefore, how to develop a kind of neutral, safe and environment-friendly to the heating with the metals such as copper, iron, aluminium and plastic part
System have preferable scale removal, derusting and except microorganism viscosity mud effect, and will not generate anticaustic is those skilled in the art's cause
Power is in one of solving the problems, such as.
Summary of the invention
The neutral cleaners and preparation method thereof that the object of the present invention is to provide a kind of for the closed system of heating, to understand
Certainly conventional clean agent causes serious pollution to the environment, is unsuitable for the household heating system of various metals material composition, and can generate secondary corruption
The problem of erosion.
To achieve the goals above, present invention employs following technical solutions:
The present invention provides a kind of neutral cleaners for the closed system of heating, the raw material including following parts by weight: high score
