Abstract
The invention relates to a degreasing agent for the pre-treatment of anodic oxidation of aluminum and an alloy thereof, and preparation and using methods for the degreasing agent. Each liter of degreasing agent mainly comprises the following ingredients: 5 to 15g of sulfuric acid, 5 to 15g of phosphoric acid, 5 to 15g of nitric acid, 5 to 15g of hydrofluoric acid, 1 to 3g of surfactant and 4 to 6g of sodium persulfate. The using method comprises the following steps of: preparing the degreasing agent in a tank, raising the temperature of tank liquor, and cleaning a product after the temperature reaches 40 DEG C, wherein the temperature of newly prepared tank liquor does not exceed 55 DEG C; and the cleaning time is controlled to be about 15 seconds. By the degreasing agent and the preparation and using methods, the disadvantages caused by the traditional process can be overcome; and the using method is easy to control, and substrates cannot be damaged easily.
Description
Technical field
The present invention relates to a kind of burning pre-treating technology, in particular, relate to a kind of grease-removing agent and preparation and method of use that is used for aluminium and alloy material anodic oxidation pre-treatment thereof.
Background technology
The pre-treating process of aluminium and alloy anode oxidation thereof prolongs the iron and steel oil removing process of usefulness in early days always.Concrete weakly alkaline solution yellow soda ash, water glass, the sodium radio-phosphate,P-32 solution of adopting, service temperature is 40～70 ℃.Its use characteristics is stable, and the life-span is long, but the tank liquor cost is high, is difficult for cleaning.Basic solns such as sodium hydroxide, yellow soda ash, sodium phosphate, complexing agent, nonionogenic tenside, AS are adopted in the back; Though the technology oil removal efficiency is high; Cost is low, and is energy-conservation, but tank liquor is easy to generate flocks; Complexing agent, tensio-active agent are prone to bring into follow-up groove, cause new pollution.
Summary of the invention
The present invention is directed to the technical problem that above-mentioned prior art exists, propose grease-removing agent and the preparation and the method for use of a kind of aluminium and alloy anode oxidation pre-treatment thereof, not only can eliminate the deficiency that traditional technology is brought, and control easily, survivable base material.
For achieving the above object, the present invention realizes through following technical scheme:
A kind of grease-removing agent that is used for aluminium and alloy anode oxidation pre-treatment thereof, mainly form by following composition and content:
Sulfuric acid: (5～15) g/L, phosphoric acid: (5～15) g/L, nitric acid: (5～15) g/L, hydrofluoric acid: (5～15) g/L, tensio-active agent: (1～3) g/L, Sodium Persulfate: (4～6) g/L, wherein: g/L representes the volume mass ratio.
Said grease-removing agent mainly is made up of following composition and content: sulfuric acid: 8g/L, phosphoric acid: 9g/L, nitric acid: 7g/L, hydrofluoric acid: 7g/L, tensio-active agent: 1.5g/L, Sodium Persulfate: 3.5g/L.
Be used for the preparation method of the grease-removing agent of above-mentioned aluminium and alloy anode oxidation pre-treatment thereof, comprise the steps:
1) 90% of needs configuration grease-removing agent TV pure cold water;
2) successively at interval 5 minutes, sulfuric acid, phosphoric acid, nitric acid, hydrofluoric acid are slowly injected solution while stirring;
3) leave standstill a moment, tensio-active agent and Sodium Persulfate are slowly dropped into successively;
4) add pure cold water again to the grease-removing agent TV that needs configuration;
5) fully can use after the stirring.
Be used for the method for use of the grease-removing agent of above-mentioned aluminium and alloy anode oxidation pre-treatment thereof, comprise: the said grease-removing agent of configuration in groove, heating tank liquid temp; After reaching 40 ℃; Product is cleaned, and the tank liquor temperature of new configuration is no more than 55 ℃, and scavenging period was controlled at about 15 seconds.
Method of use by the grease-removing agent that is used for aluminium and alloy anode oxidation pre-treatment thereof of above-mentioned preparation method preparation; Comprise: the said grease-removing agent of configuration in groove; The heating tank liquid temp, reach 40 ℃ after, product is cleaned; The tank liquor temperature of new configuration is no more than 55 ℃, and scavenging period was controlled at about 15 seconds.
Behind the grease-removing agent life-time service provided by the present invention, need not change tank liquor, only needing to add after analyzing needs the amount of composition to get final product, and has practiced thrift production cost greatly.And adopt new process method, and abandon traditional alkaline degreasing technology, can eliminate the deficiency that traditional technology is brought fully with acid deoiling technology, and also control easily, survivable base material.
Embodiment
Below in conjunction with specific embodiment, further set forth the present invention.These embodiment are interpreted as only being used to the present invention is described and are not used in restriction protection scope of the present invention.After the content of having read the present invention's record, those skilled in the art can do various changes or modification to the present invention, and these equivalences change and modify and fall into claim of the present invention institute restricted portion equally.
In the grease-removing agent of aluminium that present embodiment provides and aluminium alloy anode oxide pre-treatment thereof, each component adopts following proportioning:
The preparation process of above-mentioned grease-removing agent is (is example with preparation 10L grease-removing agent) as follows:
Measure the pure cold water of 9.5L; With sulfuric acid 80g, phosphatase 79 0g, nitric acid 70g, Hydrofluoric Acid 70 g, successively slowly in the pan tank; Tank liquor is slowly stirred on the limit; Leave standstill after 5 minutes tensio-active agent 15g, Sodium Persulfate 35g successively slowly in the pan tank, are added pure cold water to 10L then, fully stir and get final product.
The grease-removing agent of above-mentioned preparation only needs the heating tank liquid temp in use, reach 40 ℃ after, just can cleaning products.Should be noted that temperature controlling in the process.For the tank liquor temperature of new configuration not above 55 ℃. scavenging period also will be controlled at about 15 seconds.
