Abstract
The invention relates to a cleaning agent specially for an aluminum product. The weight percentage for the components is as follows: inorganic acid 15 to 45 percent, organic acid 3 to 8 percent, surface active agent 5 to 12 percent, penetrating agent 8 to 15 percent, organic solvent 10 to 20 percent and water 25 to 35 percent. The invention has simple yet scientific mechanism of action, convenient use and notable effect. The invention can clean the surface of the aluminum product rapidly in a soaking mode at a normal temperature, can effectively eliminate the white patches, the mildew stains, oil stains and zinc stearate on the surface of the aluminum product and can permanently eliminate the white patches and the mildew stains on the surface of the aluminum product. In addition, the invention has a wide source of raw material, which is easy to be obtained and has a low cost. The invention is fit for a mass industrial production.
Description
Technical field
The present invention relates to the chemical field, particularly a kind of special-purpose cleaning agent for aluminum products.
Background technology
Aluminium, must clean aluminium material surface to this class aluminum profile extrusion the time completely because of being easy to generate pollutents such as hickie, mildew, greasy dirt, Zinic stearas in infiltration, environment, the course of processing, to remove foreign material such as hickie on the aluminium material surface, mildew.Clean at present the scavenging solution that aluminium foreign material institute generally uses and mainly comprise two classes: a class is an alkaline cleaning fluid, behind this scavenging solution cleaning aluminium, and the easy variable color of aluminium, and white dot appears on the aluminum casting surface; One class is an acidic cleaning solution, behind this scavenging solution washing aluminium, hickie can occur, mildew can occur under the weather of humidity.All hickie can appear by the existing as can be seen scavenging solution of above-mentioned narration after handling aluminium material surface.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art and a kind of special-purpose cleaning agent for aluminum products is provided, this clean-out system is an acidic cleaner, foreign material such as aluminium material surface hickie, mildew, greasy dirt, Zinic stearas can be effectively removed, and hickie, the mildew of aluminium material surface can be forever removed.
Realize that technical scheme of the present invention is:
A kind of special-purpose cleaning agent for aluminum products, its component and weight proportion are respectively:
Mineral acid 15-45%
Organic acid 3-8%
Tensio-active agent 5-12%
Permeate agent 8-15%
Organic solvent 10-20%
Water 25-35%.
And, described mineral acid be phosphoric acid and vitriolic mixture, with the mixture of hydrochloric acid; The perhaps mixture of phosphoric acid and sulfuric acid and hydrochloric acid mixture.
And described organic acid is a citric acid.
And described tensio-active agent is the mixture of octyl phenol Soxylat A 25-7-10 and triethanolamine oleate, and its blended part by weight is 10: 1.
And described permeate agent is a fatty alcohol-polyoxyethylene ether.
And described organic solvent is a butyl glycol ether.
And, weight ratio sulfuric acid in described sulfuric acid and the hydrochloric acid mixture: hydrochloric acid=5: 1.
Advantage of the present invention and beneficial effect are:
1. the present invention is an acidic cleaner, and raw materials used is organic acid, mineral acid, tensio-active agent and solvent composition, and raw materials used wide material sources, obtains easily, and cost is lower, is suitable for large-scale industrial production.
2. the simple science of the mechanism of action of the present invention, at first be to adopt permeate agent and solvent to be penetrated into aluminium material surface, then under the effect of organic acid, mineral acid and tensio-active agent, remover in the aluminium material surface is cleaned up, so aluminium hickie can not occur again after cleaning, and under the weather of humidity mildew can not appear yet, be specially adapted to the cleaning of aluminum casting.
3. the present invention uses simply, effect is obvious, can clean aluminium material surface rapidly by the mode of soaking at normal temperatures, can effectively remove foreign material such as aluminium material surface hickie, mildew, greasy dirt and Zinic stearas, and can forever remove hickie, the mildew of aluminium material surface, having overcome the defective of prior art effectively, is the substitute products of existing aluminum material cleaning agent.
