Abstract

The invention discloses an oxalic acid cleaning agent which is prepared from following components, by mass, 0.5-2 parts of oxalic acid, 1-3 parts of sulfuric acid, 0.2-0.5 parts of formic acid, 0.5-2.5 parts of ammonium citrate, 2-3 parts of EDTA-NH4, 0.2-0.6 parts of a corrosion inhibitor, and the balanced water. The oxalic acid cleaning agent is less in metal corrosion, can effectively protect metal equipment from corrosion, is good in cleaning effect, can even clean fine and tiny gaps inside equipment cleanly, can clean the equipment completely, is easy to prepare and is low in production cost.

Description

A kind of oxalic acid clean-out system
Technical field
The present invention relates to a kind of clean-out system, particularly relate to a kind of oxalic acid clean-out system.
Background technology
Clean-out system of a great variety, comprises inorganic cleaning and the large class of organic washing two.Briefly, organic clear numerous agent is exactly the clean-out system made containing carbon compound, and inorganic clear numerous agent is exactly the clean-out system that carbon-free compound is made, and therefore they belong to inorganics in the difference of organic washing agent and inorganic clean-out system.The sorting technique of clean-out system is also a lot, and each state is all not quite similar, and we are divided into water system usually, half water system, non-water solubility scour three major types.
Before adopting water technology at device, adding water conditioner, the reply interchanger of circulating water system and pipeline etc. clean in advance, with impurity such as wipe oil, silt, floating rust, to reach the object purifying metallic surface.Cleaning is a very important treating processes, because it is directly connected to pre-film and the normal running from now on of water treatment.It is contemplated that, if there is the impurity such as a large amount of greasy dirt, silt, floating rust in heat exchanger and pipeline, so the protective membrane of inhibiter is just difficult to be formed, or pre-film effect can be made sharply to decline.Meanwhile, turbidity that is as seriously polluted in cooling system or water coolant is very high, can cause dirt deposition again.Therefore, the normal effectiveness of purify waste water for reasonable employment treatment agent, performance water conditioner, first cleans equipment and purification is very important.
Put into operation to new device and no doubt have the problem of cleaning, for the device run after a while, before again driving through maintenance, the corrosion in heat exchange system and dirt also need to clean.Therefore, cleaning process is not makeshift, but the requisite day-to-day work of factory's normal running.
Summary of the invention
The present invention relates to a kind of oxalic acid clean-out system, be characterized in little to metal protection, effective protection hardware is not corroded; and cleaning performance is good, the inner tiny gap of attached device also can clean up, and can clean thoroughly equipment; and preparation method is simple, production cost is lower.
A kind of oxalic acid clean-out system, it is characterized in that, each component material and mass fraction thereof are: oxalic acid 0.5 ~ 2 part, 1 ~ 3 part, sulfuric acid, 0.2 ~ 0.5 part, formic acid, ammonium citrate 0.5 ~ 2.5 part, EDTA-NH 42 ~ 3 parts, inhibiter 0.2 ~ 0.6 part, surplus is water.
A kind of manner of formulation of oxalic acid clean-out system is: by the oxalic acid of aforementioned proportion, sulfuric acid, formic acid, ammonium citrate, EDTA-NH 4, inhibiter, add in a certain amount of water, stir and can obtain.
Embodiment
Embodiment 1:
To prepare oxalic acid clean-out system 100g:
Oxalic acid 0.5g, sulfuric acid 3g, formic acid 0.5g, ammonium citrate 1g, EDTA-NH 43g, inhibiter 0.3g, surplus is water.
A kind of manner of formulation of oxalic acid clean-out system is: by the oxalic acid of aforementioned proportion, sulfuric acid, formic acid, ammonium citrate, EDTA-NH 4, inhibiter, add in a certain amount of water, stir and can obtain.
In above-described embodiment, apply rational proportioning, and suitable method, this product obtained has good cleaning effect, can dirt effectively on eliminating equipment and corrosion.
Embodiment 2:
To prepare oxalic acid clean-out system 100g:
Oxalic acid 1.5g, sulfuric acid 2.5g, formic acid 0.3g, ammonium citrate 2g, EDTA-NH 43g, inhibiter 0.5g, surplus is water.
The manner of formulation of oxalic acid clean-out system is identical with embodiment 1.
In above-described embodiment, have changed the mass fraction of each material, make the product obtained have good cleaning performance, its simple preparation method and cheap cost can make this product be widely used.
In sum; the present invention has metal protection little; effective protection hardware is not corroded; and the feature such as cleaning performance is good; and the inner tiny gap of attached device also can clean up, and can clean thoroughly, in addition to equipment; also there is preparation method simple, the advantage that production cost is lower.
Although done detailed description, protection domain has been not limited thereto.
