Abstract
The invention discloses a three acid polishing and flattening fog inhibitor used on a furniture aluminum section. The fog inhibitor is made from the following components by weight: 70-85% of phosphoric acid, 6-12% of sulfuric acid, 3-9% of nitric acid, 0.5-3% of boracic acid, 1-5% of potassium sulfide and 1-3% of magnesium oxide. The operation flow of the chemical polishing working procedures comprises the following steps: (1) removing oil stains from surfaces of an aluminum section according to the conventional oil removal working procedures; and (2) chemical polishing: at first, soaking and cleaning the aluminum section with hot water for 4-5min, then polishing in a chemical polishing and flattening fog inhibitor at the temperature of 105-110 DEG C for 4-5min, taking out and cleaning, then soaking and cleaning with 20% of dilute nitric acid by mass percent for 5-8min, and finally oxidizing and sealing holes according to the conventional procedures to obtain a finished product. The fog inhibitor avoids complex mechanical polishing working procedures, and is employed to directly perform three-acid chemical polishing on the aluminum section, which obtains the same process effect as that obtained by the mechanical polishing working procedures, reduces the aluminum section waste and environmental pollution and can significantly lower the production cost.
Description
Technical field
The present invention relates to furniture with aluminum section bar three acid polishing and leveling fog inhibitor and finishing method thereof, relate in particular to furniture is imposed chemical rightenning with aluminium shape surface and do not need the three acid polishing and leveling fog inhibitor and the finishing method thereof of mechanical polishing.
Background technology
The metallic surface chemical rightenning is the chemical etching process of metal products in polishing fluid.That chemical rightenning has is simple to operate, production efficiency is high, cost is low, be not subjected to advantages such as workpiece geomery restriction, and can make product appearance reach bright, attractive in appearance, smooth good result.Therefore, chemical rightenning is an extremely important operation during the aluminum products surface finishing is handled.
At present, furniture is carried out before traditional three acidifying optical polishings handle with aluminium section bar, must be by mechanical polishing process to remove the mould extruding striped of aluminium shape surface, smooth convex-concave surface.Mechanical polishing process is complex process not only, and produces dust in the operating process, pollutes production environment, the infringement HUMAN HEALTH.And workpiece surface is under pressure and heat affecting in the mechanical polishing process, has the surface crystal deformation layer, influences the effect that follow-up finish is handled.In addition, can produce a large amount of oxynitride (mainly comprising nitrogen protoxide and nitrogen peroxide) gas (tobacco), serious environment pollution in traditional aluminum products three acidifying optical polishing treating processess.
In order to address the above problem, people have developed some new chemical rightenning technology.For example the 200510035557.X patent of invention has proposed a kind of polishing fluid, and this polishing fluid contains phosphoric acid 60%～90%, sulfuric acid 5%～30%, liquid organic acid 3%～10%, solid organic acid 1%～5%, thiocarbamide or polyvalent alcohol 0.5%～3% by mass percentage.Do not contain nitric acid in the polishing fluid, belong to the environmental-protecting chemical polishing fluid.But this polishing fluid only is applicable to small-sized aluminum or aluminum alloy spares such as computer aluminium hard disk bracing frame, and illustrates in this patent the polishing fluid that adopts invention carries out whether also needing aluminum component is carried out mechanical polishing before the chemical rightenning processing.In addition, the production cost of this polishing fluid is higher.
Summary of the invention
The purpose of this invention is to provide a kind of furniture with aluminum section bar three acid polishing and leveling fog inhibitor and finishing method thereof, accomplish need not mechanical polishing process, and the rumbling compound prescription is simple, process stabilizing, low production cost.
Technical scheme of the present invention is as follows:
The invention provides a kind of furniture aluminum section bar three acid polishing and leveling fog inhibitor, the mass percent of each component is: phosphoric acid 70%～85%, sulfuric acid 6%～12%, nitric acid 3%～9%, boric acid 0.5%～3%, potassium sulphide 1%～5% and magnesium oxide 1%～3%.
Wherein the mass percent concentration of phosphoric acid is 85%, and the vitriolic mass percent concentration is 98%.
The process for preparation of above-mentioned three acid polishing and leveling fog inhibitor is: at first prepare phosphoric acid, sulfuric acid and nitric acid and obtain three sour basal liquids, add boric acid and magnesium oxide then successively in three sour basal liquids, add potassium sulphide at last.
The present invention also provides a kind of furniture aluminum section bar three acid polishing method, and this method may further comprise the steps:
First step: oil removing operation is routinely removed the greasy dirt of aluminium shape surface;
Second step: carry out chemical rightenning;
The operating process of described chemical rightenning operation is: hot water wash → chemical rightenning → washing → pickling → oxidation → sealing of hole; At first the aluminium section bar after the described oil removing of step (1) is embathed 4min～5min with hot water, in 105 ℃～110 ℃ three acid polishing and leveling fog inhibitor, polish 4min～5min then, take out to clean the back and in mass percent is 20% dilute nitric acid solution, embathe 5min～8min, program is carried out oxidation, sealing of hole routinely at last, obtains finished product.
In polishing process, three sour basal liquids make dissolvings rapidly such as the burr, fin of aluminium shape surface.Principal constituent phosphoric acid wherein generates the aluminum phosphate mucous membrane at aluminium material surface, and the mucous layer at surperficial protrusion place is thin than recess, so the dissolution rate of protrusion place aluminium is very fast.Sulfuric acid can suppress the point-like corrosive and occur.Nitric acid forms oxide film by oxygenizement at aluminium material surface when carrying out corrosion reaction, this layer oxide film dissolved by acid again, when the generation of oxide film and dissolving reach running balance, can obtain level and smooth glossy surface.Boric acid has shock absorption, can stablize the pH value of aluminium material surface recess, delays the dissolving of recess aluminium, has further improved the leveling effect.Potassium sulphide and magnesium oxide can be protected the aluminium material surface after the polishing, eliminate the current mark defective, and the transfer time of proper extension from polishing trough to washing bath, have also reduced the tank liquor drag-out when reducing operation easier.In addition, magnesium oxide forms one deck foam on the tank liquor surface, and the oxynitride tobacco that has produced when having hindered polishing operation distributes in air, can effectively improve Working environment, be of value to the healthy of operator, and meet the environmental requirement of emphasizing day by day and paying attention at present.
Compared with the prior art, the present invention has following beneficial effect:
Omitted the complicated mechanical polishing process, aluminium section bar has directly been carried out three acidifying optical polishings, obtained and the identical technological effect of process mechanical polishing process, reduced aluminium consume and environmental pollution, and can reduce polishing cost 40%.Aluminium shape surface after the present invention handles smooth in appearance smooth, luminance brightness is high.Surfaceness detects the surfaceness R that shows aluminium section bar
aBefore (profile arithmetic average error) polishing is 0.402 μ m, is 0.023 μ m after the polishing.
