Abstract
The invention relates to a novel environment-friendly type rapid strong deoiling and derusting agent, which is mainly applied to a process for derusting, deoiling and passivating steel. The deoiling and derusting agent consists of the following compositions: 2 to 8 portions of hydrochloric acid, 8 to 12 portions of water, 1 to 3 portions of additive consisting of sodium dodecyl benzene sulfonate, OP-10, detergent, synergist, penetrant and the like. The deoiling and derusting agent has the main characteristics: (1) the deoiling and derusting agent has no toxicity, environmental protection, energy conservation and small environmental pollution; (2) the deoiling and derusting agent has high derusting efficiency, can rapidly remove oil stains, rusty stains, oxidation films and other substances on the surface of metal in order that a phosphating film has even and fine crystal; (3) the deoiling and derusting agent does not produce the phenomena of excessive erosion and crispness; and (4) the deoiling and derusting agent has no abnormal taste and no pungent smell escaping.
Description
Technical field:
The present invention relates to a kind of rust remover, relate to especially that a kind of environment protection type rapid strong descales, oil removing, passivation, rust remover.The invention belongs to metallic surface clean technical field.
Background technology:
In the iron and steel long-term storage environment in the open, because the oxidation of iron and steel has brought certain difficulty for depositing of iron and steel, the whole world is because the corrosion of iron and steel just accounts for most of iron and steel waste loss.Present derusting method mainly contains mechanical process and chemical method two big classes: mechanical process has manually strikes shovel, polishing and the processing of sandblasting, shortcoming is that big, the dry sound of labour intensity is big, efficient is low, dust pollution is serious, and be subjected to the shape restriction of member, can not handle clean.Effective, simple to operate, the low cost and other advantages of efficient high technology that chemical method has.But under the present circumstances, also there is a large amount of liquid rust removers constantly to appear on the market, because technology is also not overripened.What now often see still is the rust remover of main batching with the mineral acid, and its main drawback is that long-time the use is corrosive to metal, and the reality of the pollution of inorganic pickling, liquid waste disposal difficulty also is difficult to solve for the moment.In order to adapt to the theme of the environmental protection that globalizes, the rust remover that must develop a kind of asepsis environment-protecting reaches the effect of environmental protection rust cleaning.
Summary of the invention:
In order to overcome the deficiencies in the prior art, the invention provides a kind of can work at normal temperatures, nontoxic, intensity is high, sticking power good, the environment protection type rapid strong rust remover of environmental protection.Component of the present invention comprises: hydrochloric acid, water, additive (compositions such as the basic sodium sulfonate of dodecane, OP-10, detergent, synergistic agent, permeate agent), preparation process of the present invention is that above-mentioned proportioning had both been made environment protection type rapid strong rust remover of the present invention after dissolving respectively, mix, stir, diluting.
Main performance index of the present invention is: outward appearance: milk yellow liquid, pH value: 3-4, relative density: 1.29g/m
-3, point of ignition: do not fire, benzene content:＜2.6 * 10
-4G, usage quantity 150g/m
2, corrodibility: carbon steel, stainless steel, brass, aluminium are not had corrosion phenomenon.
Concrete embodiment:
The present invention is described in further detail below in conjunction with concrete embodiment: each component concentration of the present invention is: hydrochloric acid (2-8 part), water (8-12 part), additive (compositions such as the basic sodium sulfonate of dodecane, OP-10, detergent, synergistic agent, permeate agent) (1-3 part), this product be applicable to embathe, visit wash, spray and ultrasonic cleaning, for example when embathing, can clean up in 10-20 minute under the room temperature.Take out the back natural air drying, pressurized air dries up or the following warm air drying of 65 degree is handled.
Main characteristics of the present invention are: 1) nontoxic, environmental protection and energy saving, and very little to the pollution of environment; 2) derust The efficient height. Can take off fast except materials such as metal surface greasy dirt, rust agent, oxide-films, make the phosphatization membrane crystallization even, Fine and closely woven; 3) the metal matrix is not produced excessive erosion and clear and melodious phenomenon; 4) rust remover free from extraneous odour, non-stimulated property Smell is overflowed.
Claims (3)
1, a kind of environment protection type rapid strong rust remover, its each component composition and content comprise: hydrochloric acid (2-8 part), water (8-12 part), additive (compositions such as the basic sodium sulfonate of dodecane, OP-10, detergent, synergistic agent, permeate agent) (1-3 part) etc.
2, environment protection type rapid strong rust remover according to claim 1 is characterized in that main performance index of the present invention is: outward appearance of the present invention: milk yellow liquid, pH value: 3-4, relative density: 1.29g/m
-3, point of ignition: do not fire, benzene content:＜2.6 * 10
-4G, usage quantity 150g/m
2, corrodibility: carbon steel, stainless steel, brass, aluminium are not had corrosion phenomenon.
3, environment protection type rapid strong rust remover according to claim 1 is characterized in that main technique flow process of the present invention is:
