Acid rust remover
Technical field
The present invention relates to a kind of clean-out system, specifically, relate to a kind of acid rust remover that is used for mechanical means.
Background technology
The cleaning of mechanical means be these parts process, assemble, store and process such as maintenance in indispensable process procedure.After normal operation for some time, the suspended substance that may exist during reverse-osmosis membrane element can be fed water or the pollution of difficulty soluble salt, modal during these pollute is precipitation of calcium carbonate, calcium sulfate precipitation, metal (iron, manganese, copper, nickel, aluminium etc.) oxide precipitation, rusty stain, inorganic or organic deposit mixture, natural organic substance, synthesis of organic substance.Because the consumption of mechanical means is quite big, therefore the workload of this class mechanical means cleaning and the usage quantity of clean-out system also are certain to corresponding increase.At present,, mainly contain the method for embathing, hydro-peening method and ultrasonic cleaning process etc., no matter take which kind of purging method, all need to use clean-out system the purging method of mechanical means.Existing be used for mechanical equipment detergent and mostly be solvent-borne type, the shortcoming that these clean-out systems exist at first is that cleaning performance is not really desirable, and the top layer of black appears in mechanical means material after the cleaning easily, make troubles to following process, the processing to precision components causes puzzlement especially; Next is stronger to equipment corrosion, increases equipment cost; Moreover, cleaning temperature and scavenging period are difficult to reach simultaneously ideal conditions, under the constant situation of cleaning performance, at high temperature clean often, can shorten scavenging period, cleaning temperature is reduced under the situation of room temperature, and scavenging period just needs to prolong, and generally scavenging period needs 10 to 30 minutes at ambient temperature.
Therefore remain to be developed a kind of rust remover of aq. type, can improve cleaning performance at ambient temperature, can also reduce corrodibility equipment.
Summary of the invention
Main purpose of the present invention is to overcome the above-mentioned shortcoming that currently available products exists, a kind of acid rust remover is provided, the effect that mechanical means is had efficient easy cleaning, mechanical means surface and oil contaminant and rust staining are cleaned thoroughly, and can prevent that the mechanical means surface from forming rust staining once more, can also shorten scavenging period, increase work efficiency; It is water-soluble rust remover, and low to the corrodibility of equipment, effectively reduces production costs, and is safe and reliable.

Preferably, acid rust remover of the present invention comprises following component according to weight percent:
Phosphoric acid salt 3~8
Permeate agent 6~10
Tensio-active agent 5~8
PH regulator agent 2~3
The deionized water surplus,
Wherein, said phosphoric acid salt is sodium phosphate or potassiumphosphate; The glycol ether compounds is ethylene glycol ethyl ether, butyl glycol ether or its composition; Fatty alcohol-polyoxyethylene ether is that the polymerization degree is that 15 fatty alcohol-polyoxyethylene ether (0-15), the polymerization degree are that 20 fatty alcohol-polyoxyethylene ether (0-25), the polymerization degree are that 35 the fatty alcohol-polyoxyethylene ether (0-35) or the polymerization degree are 40 fatty alcohol-polyoxyethylene ether (0-40); Said PH conditioning agent is a hydrochloric acid.
More preferably,

The pH value of acid rust remover of the present invention is 3 to 4, and color is a water white transparency, has no irritating odor.
Acid rust remover of the present invention has following technique effect:
1) scientific formulation of the present invention is reasonable, and production technique is simple, does not need specific installation;
2) its cleansing power is strong, and scavenging period is short, saves manpower and man-hour, increases work efficiency, and has rust cleaning and antirust effect;
3) this clean-out system is acid, lower to the corrodibility of equipment, safe and reliable, is beneficial to the reduction equipment cost;
4) tensio-active agent that contains in the mechanical equipment detergent of the present invention can make mechanical means form compact protective film on the surface through meeting after cleaning, thereby the part after having guaranteed to clean has antirust function.Permeate agent improves the cleanup action of scavenging solution
