Problems solved by technology

[0004] At present, most aluminum profile factories use manual dosing. Nickel ion salt is generally used in the sealing bath, and nickel ion salt is not easy to dissolve. Good guarantee the continuous stability of the concentration of the bath solution, and the phenomenon of incomplete dissolution occurs from time to time due to too much dosage at one time, which makes it difficult to eliminate the phenomenon of drug waste

Abstract

The invention discloses an automatic adjusting system of a hole sealing bath solution for an aluminum profile, and relates to the technical field of aluminum profile surface treatment. The automatic adjusting system of the hole sealing bath solution for the aluminum profile comprises a hole sealing bath body, a medicine adding barrel in which a mixer is arranged, and a PLC, wherein a nickel salt adding port equipped with a solid adding valve, a solvent adding port equipped with a liquid adding valve, a medicine outlet and a liquid level meter are arranged on the medicine adding barrel; the liquid level meter is positioned above the medicine adding barrel and faces the liquid level of the medicine adding barrel; a medicine inlet and an infrared sensor are arranged on the hole sealing bath body; the medicine outlet is connected with the medicine inlet through an electromagnetic diaphragm pump; the infrared sensor is arranged at the upper end of the hole sealing bath body and faces the upper part of the liquid level; the PLC is connected with the solid adding valve, the liquid adding valve, the electromagnetic diaphragm pump, the infrared sensor and the mixer. With the adoption of the automatic adjusting system, the quantity of used medicines can be effectively decreased, and the product quality stability can be ensured.

Description

technical field [0001] The invention relates to the technical field of surface treatment of aluminum profiles, in particular to an automatic adjustment system for aluminum profile sealing bath liquid. Background technique [0002] It is known that aluminum and its alloys will oxidize when exposed to the air, so that a layer of oxide film is naturally formed on the surface, which will make the surface of aluminum metal lose its original luster, although this layer of oxide film will slightly passivate the surface of aluminum metal , but it is very thin and has large porosity and poor mechanical properties. It cannot effectively prevent further corrosion of aluminum metal by various media in the atmosphere; the so-called anodic oxidation of aluminum is an electrolytic oxidation process. In this process, aluminum And the surface of aluminum alloy is usually transformed into a layer of oxide film. [0003] Most anodizing manufacturers combine various types of surface treatment ...
