Abstract
The invention relates to an acidic rust remover which comprises the following components according to percentage by weight: 3%-10% of phosphate, 5%-10% of osmotic agent, 5%-10% of surface active agent, 1%-6% of pH conditioning agent and the balance of deionized water. The pH value of the acidic rust remover ranges from 10 to 12, and the acidic rust remover is colorless and transparent and has no penetrating odor. The acidic rust remover is highly efficient in cleaning a mechanical apparatus and can completely clear oil stains and rusty spots on the surface of the mechanical apparatus, prevent the rusty spots from being generated on the surface of the mechanical apparatus again, shorten the time for cleaning and improve the work efficiency; and the acidic rust remover is a water-soluble cleaning agent, hardly corrodes the apparatus, effectively reduces the production cost and is safe and reliable in use.
Description
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.
