What causes the phenomenon of aluminium pigments leaving marks? With the development of the economy, people's knowledge of aluminium pigment has become deeper and deeper, and many people have started to pay attention to the spray-free injection moulding industry. We all know that cell phones and cars generally need to be painted, in order to improve the painting process, some companies have started to use spray-free technology, which indirectly leads to the phenomenon of leaving marks due to technical problems in the process of spraying. So, what is the cause of the aluminium pigments leaving marks phenomenon? Let Sunrise give you a brief introduction.
What is the reason of the aluminium pigment leaving marks phenomenon? As far as I konw, the spray-free material is made of aluminium pigment pellets and can be injected directly and can achieve colourful appearance without spraying. Therefore, we need to understand what is aluminium pigment pellet before understanding the cause of the phenomenon of leaving marks.
Aluminium pigment pellet is made from aluminium paste with excess solvent removed and rich additives added, extruded into a column of 2mm diameter and 8-10mm in length. Generally, the pigment pellets can be applied to plastic systems, mainly for home appliances, car interiors, cell phone cases, films, section bars and masterbatches, etc. It is commonly used in PE, PP, PC, PC/ABS, ABS, PS, PA and other materials.
So, what is the cause of the phenomenon of leaving marks? In fact, it is related to the aluminium pigments or aluminium pigment pellets used. There are two things to do with aluminium pigment pellets that leave marks on injection moulded parts, one is the selection of the aluminium pigment pellet, and the second reason is the dispersibility of the aluminium pigment pellet. The aluminium pigment pellet produced by Sunrise are used to change the basic performance of aluminium paste through additives, so that it can be better dispersed in the substrate, and then it can be evenly dispersed into the plastic during the use process, without gathering or not dispersing.
The above is the introduction of "what causes the phenomenon of aluminium pigment leaving marks", hope it will be helpful to you. Thank you for your careful reading, if you like our information, you can continue to follow us.
