Aluminum paste detection device and detection method thereof

Abstract

The invention provides an aluminum paste detection device and a detection method thereof. The detection device comprises a water bath kettle, a three-necked flask and a U-shaped connector, wherein thethree-necked flask is arranged on the water bath kettle; one end of the U-shaped connector is connected with the upper outlet of the three-necked flask through a tube; the U-shaped connector is filled with liquid inside; and the other end of the U-shaped connector is provided with scales. The aluminum paste detection device provided by the invention has the advantages of simple structure and highoperability; and the quality of aluminum paste can be rapidly and efficiently detected by using the detection device.

Description

technical field [0001] The present invention generally relates to the field of coatings, and in particular, relates to an aluminum-silver paste detection device and a detection method thereof. Background technique [0002] Aluminum paste (Aluminum paste) is a paste-like metallic pigment that has been processed by a certain process. The aluminum shapes are snowflake-like, fish-scale-like, and silver-dollar-like. It is characterized by smooth and flat surface of aluminum flakes, concentrated particle size distribution, regular shape, excellent light reflection ability and metallic luster, mixed with transparent pigments, the paint film has obvious "angle-dependent color effect" and better covering performance , the decorative effect is very gorgeous and beautiful. Mainly used in automotive coatings, metal industrial coatings, marine coatings, plastic coatings, heat-resistant coatings, etc. [0003] Water-based coatings have become the direction of future coatings development...

Problems solved by technology

[0007] However, there are many defects in the water-based aluminum-silver paste at this stage. For example, because the cost reduction is only passivation of the aluminum powder, it can only be adjusted and used immediately; for example, the protective film coated with some aluminum-silver paste is too thin and damaged, and the water-based paint produced is There will be adverse reactions such as flatulence and swelling of the tank. This is because the exposed aluminum powder reacts with water to produce hydrogen gas. If you open the lid rashly, it is easy to fly the lid off. Hydrogen gas is also prone to explosion when it encounters an open flame.

For inferior water-based aluminum silver paste, especially in summer when the temperature is too high, because the reaction rate becomes faster at high temperature, there are certain hidden dangers to the storage and transportation of the finished paint
