With the simple and safe application this approach is the favorite of the test. The piezobrush® PZ3 in use on the powder-coated aluminium profile.
Chat Online· However before use powders need adequate surface treatment in order to acquire new surface properties required in the different applications. Nanosized SiC was synthesized by the solid-state method followed by plasma treatment. Solid state-synthesized SiC particles were 1–5 µm in size whereas the plasma-synthesized particles were below 30 nm.
Chat OnlinePlasma treatment can effectively plasma clean or plasma activate the surfaces of powder. It also has the ability to create hydrophilic properties in the powder through increasing the wettability. The contact angle decreases while the surface energy increases as the powder is treated for a longer period of time.
Chat OnlinePlasma powder activation. Furthermore hydrophilic PE powder can increase the bonding strength between metal and plastic. This hydrophilization is made possible by low-pressure plasma treatment.The treatment parameters strongly depend on the particle size of the powder. Plasma treatment can take between 5 minutes and several hours. Thermal damage to the powder is excluded since the process
