Abstract
The invention discloses an aluminium product polishing method. The method is characterized by comprising the following steps: I, preparing a chemical polishing solution comprising 3-12 parts of brightening agent, 3-12 parts of corrosion inhibitor, 20-65 parts of phosphoric acid and 25-75 parts of sulfuric acid by weight, wherein the total parts by weight is 100; the brightening agent comprises 1-4 butynediol and glycerin; and the corrosion inhibitor comprises phytic acid and polyphosphoric acid; II, heating the polishing solution to 85-120 DEG C; III, soaking a dry and clean aluminium product to be polished in the polishing solution in the step II for 20-240 seconds; IV, taking out the aluminium product in the step III and then washing the aluminium product with deionized water at 60 DEG C twice; and V, taking out and then blow-drying the aluminium product in the step IV.
Description
Technical field
The present invention relates to the finishing method field of metal products, particularly relate to a kind of finishing method of aluminum products.
Background technology
At present, the finishing method of the aluminum products used both at home and abroad, " three acid " chemical brightening solution that many employings are traditional, due to the use of nitric acid, produce a large amount of tobacco during polishing, can cause topsoil, serious harm workman's is healthy; " two acid " chemical brightening solution not containing nitric acid of prior art employing, although solve the technical problem of tobacco harm, polishing effect is not good, and aluminum products surface gloss is inadequate, bright not.
Summary of the invention
The technical problem to be solved in the present invention is: eliminate the tobacco harm that nitric acid brings; Aluminum products surface finish is not good, the technical problem that surface of polished becomes clear not.
Technical solution of the present invention is: the finishing method disclosing a kind of aluminum products, is characterized in that, comprises the following steps:
Step one, preparation chemical brightening solution, counts: comprise brightening agent 3 ~ 12 by weight, inhibiter 3 ~ 12, phosphoric acid 20 ~ 65, sulfuric acid 25 ~ 75, be made into 100 parts, described brightening agent is made up of 1-4 butynediol and glycerine, and described inhibiter is made up of phytic acid and polyphosphoric acid;
Step 2, is heated to 85 DEG C ~ 120 DEG C by polishing fluid;
The polished aluminum products of dried and clean are immersed in the polishing fluid in step 2, soak 20S ~ 240S by step 3;
Step 4, washes twice with the deionized water of 60 DEG C after being taken out by the aluminum products in step 3;
Step 5, dries up after being taken out by the aluminum products in step 4.
The present invention compared with prior art, has the following advantages:
The polishing fluid of aluminum products disclosed by the invention replaces traditional aluminium three acid (phosphosulfate nitric acid) aluminum products polishing fluid, sewage discharge can be reduced, volatilize without yellow smog, process tank liquor convenient (solid substance is directly containing the container process of tank liquor), phosphoric acid usage quantity 50 ~ 75% can be reduced, save power more than 45%, glossiness is more than three sour techniques.Cost is about low by 2 ~ 5% than three acid, is the most receptible technical products of existing market.
Existing " three acid " polishing technology pollutes heavy, and three waste discharge processing cost is high, difficulty is large, cannot meet the requirement of environmental protection, particularly yellow smog pollute cannot be up to standard.
