Recognition of water-based aluminum paste

The main components of aluminum paste are flake-shaped aluminum particles and petroleum solvent, which are paste-like. Its characteristics are that the surface of the aluminum sheet is smooth and flat, the particle size distribution is concentrated, the shape is regular, and it has excellent light reflection ability and metallic luster. It is mixed with transparent color pigments. The paint film has obvious "different color effect" and the decorative effect is very gorgeous. Beautiful.

1. How to use water-based aluminum paste

Generally speaking, "water-based aluminum paste can be diluted with water directly, while oil-based aluminum paste needs to be diluted with oily solvent" is a simple detection method to distinguish the type of aluminum paste (there is also a small batch of water-based aluminum paste that cannot be directly opened with water. Rare, no more introduction here). When many factories use water-based aluminum pastes, they still choose solvents and dispersants according to the previous habit of making oily aluminum pastes, or even pour them directly into the slurry without dispersing.

When a problem occurs, it will push the problem to the water-based aluminum paste. In fact, the use of water-based aluminum paste is very simple now, it can be diluted by directly using deionized water or anti-white water, and there is no need to add any dispersant.

2. The price of water-based aluminum paste

Price is always the most concerned issue of people. Many people like to compare the price of oil-based aluminum paste with that of water-based aluminum paste. However, the two production processes are different, the technical content is different, and the most important current market scale is also different, so it is difficult to purely compare the price.

The price of water-based aluminum paste is also uneven, and its price ranges from tens of dollars to hundreds of dollars for different performance requirements. Usually the price is directly proportional to the quality. The product price is low but it cannot meet the needs of the customers. It is also ineffective. Moreover, the water-based aluminum paste is divided into different types such as secondary coating and passivation. Therefore, how to distinguish the true value of the product needs to be done more. Compare.

3. Product performance of water-based aluminum paste

At this stage, there is still a little gap between the comprehensive indicators of water-based aluminum paste and oil-based aluminum paste. On the one hand, water-based aluminum paste manufacturers are required to continuously improve their product performance, and on the other hand, they must rely on water-based resins and supporting additives to be more mature.

The above content is an introduction to take you to re-understand the water-based aluminum paste. Before using the water-based aluminum paste, we must first check the integrity of the water-based aluminum paste, and observe whether the water-based aluminum paste in the packaging barrel has agglomeration, hardening, etc. If it happens, stop using it immediately. Of course, in addition to the surface adverse reactions that our eyes can see, there are some deep-seated reactions that we can't distinguish by appearance. This requires customers to conduct a sampling test for each batch of goods to ensure the stability of product quality.
