Abstract
The invention provides a heat sink anticorrosion technology. The inner anticorrosion technology main consists of pretreatment, chemical oxidation, filling coating of paint and baking curing. The technological flow comprises degreasing, water washing, alkali corrosion, water washing, neutralizing, water washing, water washing, chemical oxidation, water washing for two times, drying, filling coating, liquid draining, baking, filling coating, liquid draining and baking. The pretreatment process employs an immersing process or a circulation process. The related heat sink anticorrosion technology is simple in technology and good in anticorrosion effect and helps to prolong the service life of a heat sink.
Description
Technical field
The present invention relates to a kind of scatterer anticorrosion process, belong to aluminum products technical field of surface.
Background technology
Aluminium alloy heat radiator has that heat transfer is fast, lightweight, volume is little, beautiful design, collecting and distributing heat are that market is favored with decorating the feature that is integrated, but shortcoming to be solidity to corrosion poor.Hot water space heating boiler is added with a small amount of scale inhibitor to prevent encrustation in heat-processed in water, and therefore the water quality of hot water space heating boiler is weakly alkaline, pH value about 9, containing a certain amount of Cl
-.Aluminium alloy heat radiator is continuously 90
ouse at the temperature of about C, easily produce needle-like corrosion leakage and scrap.
Summary of the invention
The invention provides a kind of scatterer anticorrosion process, favorable anti-corrosion effect, extend the work-ing life of scatterer.
For solving above technical problem, the invention provides following technical scheme: interior anticorrosion process is coated with coating and baking-curing composition primarily of pre-treatment, chemical oxidation, filling, and its technical process is: degreasing → washing → alkaline etching → washing → neutralization → washing → chemical oxidation → washing secondary → drying → filling is coated with → control liquid → baking → filling painting → control liquid → baking; Wherein pretreated method is immersed method or circulation method; Described immersed method immerses tank liquor process for several scatterer being placed in stainless steel or aluminium matter basket, and inner chamber to be filled after tank liquor by scatterer two end tilted upward for several times, prevents from reacting the gas hold-up that produces in inner chamber somewhere; Explosive gas generation in alkaline etching process, notes inner chamber smooth gas discharge; The hydraulic control of lifting pit to the greatest extent, is then washed, and Alkaline etchant is repeatedly repeatedly washed after using and reaching certain value to viscosity and kept the temperature in washing bath, embathes once after lifting control water again; Described circulation method is connect plastic hose in the import and export of scatterer, connects stainless steel or fluorine moulds water pump, makes tank liquor in inner chamber circular treatment and washing.
Further, the alkaline etching agent needed for described alkaline etching technique comprises Yangization Na ﹑ Qing Yangization Jia ﹑ Yangization Na ﹑ potassium oxide.
This scatterer anticorrosion process that the present invention relates to, inner anticorrosioning coating has strong adhesion, feature that solidity to corrosion is high, at PH10, Cl
-100 mg/L 95 ~ 100
ocorrode 10000 hours continuously in the solution of C, coating at all can't harm, thus effectively raises the work-ing life of scatterer.Technique is simple, and favorable anti-corrosion effect, extends the work-ing life of scatterer.
