Stirring system for reducing hydroxyl ion precipitation

Abstract

The invention relates to the technical field of metal coating processing, and discloses a stirring system for reducing hydroxyl ion precipitation, the stirring system comprises a support frame, the support frame is C-shaped, the lower surface of the inner part of the support frame is fixedly connected with a reaction stirring barrel, and the upper surface of the inner part of the support frame is fixedly connected with a hydraulic machine. A rotating shaft moves downwards to enable a fixing ring to move downwards, then the left end of a first transmission rod moves downwards in a first fixing frame and rotates, and meanwhile the first transmission rod rotates downwards to enable a first rotating rod to rotate in a second fixing frame, the left end of the first rotating rod moves downwards, the right end of the first transmission rod slides in the first rotating rod, the first transmission rod and the first rotating rod form a V-shaped structure to rotate, collision of particles in the reaction liquid can be accelerated, and then the reaction speed of the reaction liquid in the reaction stirring barrel is accelerated.

Description

technical field [0001] The invention relates to the technical field of metal paint processing, in particular to a stirring system for reducing hydroxide ion precipitation. Background technique [0002] Metallic paint is also known as metallic paint, metallic paint, metallic effect paint, aluminum powder paint, metallic paint is a paint with a metallic texture, most of which require some form of pretreatment on the metal surface to improve the surface condition, in order to improve the coating Adhesion, enhance the anti-corrosion protection of metal substrates, and metal coatings are divided into wood paints, interior wall paints, and exterior wall paints according to their uses, and the stirring and anti-liquid in the production process of exterior wall paints is very important to them Most of the stirring devices are composed of stirring rods and motors; however, the finished emulsion of the exterior wall paint is alkaline after stirring the water-soluble polyurethane resin...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a stirring system for reducing the precipitation of hydroxide ions, which has the advantages of being easy to clean the stirring device, so that the residual hydroxide in the stirring device can be cleaned in time, and solves the problem of the finished emulsion The ionized hydroxide remains on the stirring device, and then the hydroxide will react with the magnesium ions and calcium ions in the water, resulting in the precipitation of magnesium hydroxide and calcium hydroxide, which will cause dirt on the stirring device, and then make the stirring device The reaction liquid will be affected to a certain extent when the next stirring is carried out, so that the stirred finished product will be polluted to a certain extent, and the quality of the finished product will be reduced.
