Fácil material y proceso flujo de vacío galvanoplastia eléctrico calefacción tubo

1. Materiales

ABS es usualmente modificado por añadir otro resinas. Para ejemplo, añadir PC (policarbonato) puede mejorar calor resistencia, mecánica fuerza, tenacidad, etc., adicionando PMMA (polimetil metacrilato) can make transparente ABS plástico. In order to save costes, some fillers or pigmentos are sometimes added.

Generalmente hablando, puro ABS has the best electroplating effect; ABS added with PC needs to undering expansion treatment before electrovaning to improve the bonding force between the coating and the substrate; ABS added with recycled materials, fillers or pigments is difficult to guarantee the quality of electroplating. Its pretreatment process is also difficult to grasp, and the poisoning effect on the plating solution is obvious. Por lo tanto, galvanoplastia fabricantes debería entender la composición de materiales cuando galvanoplastia ABS.

2. Proceso flujo

Colgante - químico desengrasante - 2 lavados - rugosing - 2 reciclaje - 2 contracorriente enjuague - neutralización - 3 puro agua lavado - preoak - paladio activación - 3 puro agua contracorriente enjuague - desgomado - puro agua contracorriente 3 veces of enjuague—electroless níquel chapado—3 times of pure water countercurrent rinsing—copper or nickel chaping—3 veces de contracorriente enjuague—acid copper—recovery—3 times of countercurrent rinsing—semi-gloss nickel—high sulfur nickel—full-gloss nickel—nickel sealing ─ 3 times of countercurrent rinsing ─ chrome chaping ─ 3 times of countercurrent rinsing ─ pure water washing ─ water blowing ─ drying.

No copper layer can be plated on the surface of the parts; the reason for this kind of failure is generally caused by the failure of the sensitizing solution or the activation solution, and it may also be the pH value, temperature, formaldehyde, copper sulfate content in the electroless copper plating solution is too low or complex Caused by the high content of the mixture. To deal with such failures, first check whether the sensitizing solution, activation solution or colloidal palladium solution is normal. Use a small amount of newly prepared sensitizing and activating solution (or colloidal palladium solution), if the roughened plastic parts can be deposited with a copper layer after being treated with the newly prepared Minyi and activating solution, it proves that the original sensitizing solution or activating solution Ineffective, these solutions should be adjusted or replaced. If the roughened light-colored plastic parts are treated with the original sensitizing and activating solution, the surface of the parts can turn brown, indicating that the sensitizing solution and the activating solution have not failed, and the electroless copper plating solution should be checked.
