We know that in the copper-nickel-chromium plating process, there are often a variety of failures, in which the poor bonding of the plated layer is a plater often encountered, then, this issue of the article we will discuss the use of alloy chemical degreasing powder, what are the things need to pay attention to, so as to ensure that the bonding of the plated layer is good.
In general, there are five points to pay attention to, and this time we will talk about three of them.
① The temperature of the degreasing solution should not be too low. We are in the pre-treatment of degreasing link, even if the use of room temperature degreasing agent, when the temperature of the degreasing solution is lower than 20 ℃, but also to appropriate heating of the solution to ensure that its temperature is maintained at 30 ℃ or more, in this way, to achieve a better effect of degreasing.
② chemical degreasing solution should not be too single component, a variety of chemical raw materials, we need to follow the instructions of the proportion of the preparation, in this case, to give full play to their role, so as to completely remove all kinds of oil on the surface of the substrate.
③When we chemically degrease flat parts and sheet parts, the surface of these two kinds of workpieces can easily stick together, which affects the effect of degreasing, so it will result in a poor bonding of the plated layer. Therefore we take certain methods.
For these substrates, when the chemical degreasing should be placed one by one, and there are two points to pay attention to: one is to ensure that there is a certain distance between the substrate and the substrate; the other is to move a few times the position of the substrate. In this way, help to achieve the complete removal of oil on the substrate.
So, what kind of alloy chemical degreasing powder is suitable? You can use Bigely alloy chemical degreasing powder BC-1103, which can remove all kinds of grease on the substrate and does not hurt zinc, aluminum and brass substrates, with a long bath life and high efficiency. In today's environmentally friendly pressure, as BC-1103 is a non-phosphorus formula, it does not contain phosphorus, ammonia nitrogen and other pollutants, it is easily biodegradable, and the wastewater treatment is simple, which helps plating factories to reduce the cost of wastewater.
