With the improvement of people's awareness of environmental protection, environmental protection has almost become a guarantee of high-quality life. Whether it is daily travel or home life, people's choices are moving towards environmental protection. Therefore, many environmental protection companies have begun to transform water-based environmentally friendly paints. I believe everyone knows that water-based paint is derived from water-based aluminum paste. However, in the industry of water-based aluminum paste, do you really understand water-based aluminum paste? Next, let's take a look at the common problems of water-based aluminum paste and the precautions for using water-based aluminum paste!
What are the common problems of water-based aluminum paste?
Bloating phenomenon
It is mainly accompanied by continuous bubbles coming out, which can easily cause the packaging barrel to burst in a sealed space. The main reason for the product is that water-based aluminum paste is easy to react in a strong acid and alkali system.
Agglomeration reaction
It is mainly that the water-based aluminum paste has an irreversible chemical reaction with other substances in the base material. Aluminum + water + air will react to produce solid alumina and generate a lot of heat.
Silver powder arrangement
Silver powder arrangement is one of the most common problems. The solution is generally to use a silver powder arrangement agent (wetting dispersant) or adjust the paint formula.
Color difference problem
It is mainly because the water-based aluminum paste itself has a very slow self-reaction process. There will be slight differences between the newly made goods and the same batch of goods that have been placed for a period of time.
What are the precautions for using water-based aluminum paste?Dispersibility
Generally, water-based aluminum paste must be pre-dispersed before use to ensure that the water-based aluminum paste is completely dispersed. Taking our Xuyang water-based aluminum paste as an example, the recommended co-solvents are deionized water, anti-white water (ethylene glycol butyl ether), etc.
Storage environment
Generally, in order to ensure the storage time of water-based aluminum paste, it is recommended to place the water-based aluminum paste in a dry and well-ventilated warehouse. If conditions permit, the room temperature can be controlled at a more suitable temperature. For the remaining products that have been unpacked, it is necessary to seal the opening in time to prevent excessive exposure to the outside from affecting product performance.
How to place an order
Due to the particularity of the industry, it is recommended that customers who have just come into contact with the product should generally take a small sample test before placing an order. During the test, in addition to paying attention to the appearance of the product, the stability and other performance of the product should also be tested as necessary. Do not omit the necessary tests because of the trouble. After the product performance sample test, you can place an order at any time.
Regular self-inspection
Whether it is a new customer or an old customer, it is recommended to take samples in time after ordering raw materials to ensure that there are no problems in the paint system of this batch of products before large-scale production can be carried out.
