Description

Stirring device for scaling powder production

Technical Field

The utility model relates to a scaling powder is agitating unit for production.

Background

The raw materials of the soldering flux contain a foaming agent, and the foaming agent is specifically any one of n-pentane, petroleum ether and fatty alcohol-polyoxyethylene ether sodium sulfate. When the foaming agent is mixed with the other raw material rosin of the scaling powder, bubbles are formed in the mixed solution, the foaming agent can effectively reduce the surface tension of the basic solvent, the double electronic layers are arranged on the surface of the liquid film to surround air to form the bubbles, and then the bubbles form foams, so that the mixing efficiency of the synthetic surfactant and the acid solution is improved, and the active agent is prevented from being removed from the mixed solvent of the basic rosin. Therefore, the bubbles can increase the dissolution rate of the activator, promote the dissolution rate between the activator and the rosin mixed liquid, prevent solid components such as the activator from being dissolved out of the solution, and avoid poor non-uniform distribution of the activator. Therefore, the foaming agent is helpful for improving the product quality of the soldering flux. The soldering flux is prepared in a mode of stirring uniformly. After the bubbles in the mixed liquid are generated, the bubbles with small volume are polymerized into bubbles with larger volume by stirring, so that the condition that the bubbles in the mixed liquid are not uniformly distributed is caused. As mentioned above, the bubbles have a positive effect on improving the quality of the flux, and if the bubbles are not uniformly distributed, the flux cannot be efficiently mixed.

Because the surface of the support, namely the operation surface, is vertical to the rotation direction of the main rotating rod, and only the surface of the spoiler, namely the operation surface, is inclined to the rotation direction of the main rotating rod, the main rotating rod moves at a slow movement speed in the technical scheme, the support generates a turbulent flow which is symmetrical in the rotation direction of the main rotating rod in the mixed liquid, and the spoiler generates a downward turbulent flow in the mixed liquid, and the turbulent flows of the two modes guide the mixed liquid to form a flow mode from top to bottom in the barrel, so that the mixed liquid continuously flows towards the bottom of the barrel and is mixed. This operation mode can avoid main bull stick to the bubble formation shearing force, and then avoids destroying the tension on bubble surface for the bubble in the mixed liquid keeps the original form all the time, and the difficult gathering of bubble forms bulky bubble.
