Description

Clean-out system of a kind of household heating system for being made up of various metals material and preparation method thereof
Technical field
The present invention relates to a kind of clean-out system, particularly relating to clean-out system of a kind of household heating system for being made up of various metals material and preparation method thereof.
Background technology
The feature of small home heating system is: local temperature is higher, pipeline is comparatively thin in system, easily causes fouling in system, causes the phenomenons such as line clogging.Therefore, for preventing system jams from causing thermal cycling to be obstructed, this system is carried out with cleanings such as front welding slag, residues, and descaling rinsing seems very important termly.
At present, main wash mode has: mechanical descaling, high pressure water cleaning and matting.First two cleaning way much belongs to manual operations, and labour intensity is large, and be a kind of operating method of rough type substantially, suitability is also poor, inapplicable in a lot of technical process; It is wide that matting relates to, and use flexibly, for different systems and different incrustation scale kinds, the cleaning agent formula selected is also different.
The matting of general industry equipment: as boiler, pipeline, petrochemical equipment etc., usually use acid, alkali and some active substances as clean-out system.After the cleaning of this kind of clean-out system, to improve and the fundamental property of restorer, but the bad control of terminal, to have certain danger, and be unsuitable for the household heating system that various metals material forms; In addition, long-term acid, alkaline cleaner make the metallic corrosion of equipment, shorten the life-span of equipment; Further, sour, alkali cleaning operation complex procedures, need after cleaning to carry out neutralizing treatment, then passivation, make equipment cleaning time elongated, affect the normal operation of equipment.
Summary of the invention
The object of the invention is to overcome the defect of prior art and provide a kind of and can run cleaning continuously under not stopped status and be applicable to the neutral cleaners of the household heating system be made up of various metals material.
Another object of the present invention is the preparation method of the clean-out system providing a kind of above-mentioned household heating system for being made up of various metals material
The object of the present invention is achieved like this:
The clean-out system of a kind of household heating system for being made up of various metals material of the present invention, comprise the component of following weight percent content: propylene glycol 3 ~ 20%, inhibiter 2.5 ~ 10%, thionamic acid 0.1 ~ 5%, ethylene diamine tetra methylene phosphonic acid sodium 5 ~ 25%, all the other are de-mineralized water.
The clean-out system of above-mentioned a kind of household heating system for being made up of various metals material, wherein, described inhibiter is at least two kinds in benzotriazole, 1-Hydroxy Ethylidene-1,1-Diphosphonic Acid and Sodium orthomolybdate.
Present invention also offers a kind of preparation method of clean-out system of the above-mentioned household heating system for being made up of various metals material, comprising the following steps:
(1) prepare raw material according to following component and weight percent content: propylene glycol 3 ~ 20%, inhibiter 2.5 ~ 10%, thionamic acid 0.1 ~ 5%, ethylene diamine tetra methylene phosphonic acid sodium 5 ~ 25%, all the other are de-mineralized water;
(2) raw material prepared in step (1) is added successively, stir, namely obtain clean-out system of the present invention.
The present invention compared with prior art has following beneficial effect:
(1) adopt in formula and wash dirt effective thionamic acid and ethylenediamine tetraacetic pitch Alendronate composite, reach dissolvings, peel off the effect of old dirt and removing welding slag, avoid that pipeline is dirty to be blocked up;
(2) utilize multiple inhibiter composite, strengthen the corrosion mitigating effect to various metals material;
(3) this product compares with imported relay agent, shows good inhibition, scale-inhibiting properties.
Clean-out system of the present invention utilize organic anti-scale composition and organic acid composite, effectively to peel off, the old dirt dissolved in household heating system equipment, to prevent from generating secondary incrustation scale simultaneously; This clean-out system effectively can not only reduce the corrosion to household heating system equipment metallic substance, effectively can also remove the incrustation scale, anvil cinder etc. of household heating system device interior, prevent the problems such as the low or water cycle blocking of the heat transfer efficiency of the household heating system caused because of fouling, run with making each equipment energy safety economy in whole household heating system, thus reach the object reducing water pollutions and save energy and reduce the cost.
