Аналіз з причин чому колір з вакуум гальванічне покриття троянда золото є легко до вицвітання%3а

 

1. The color of rose gold is unstable (нестабільний) due to the poor performance of color concentrate or color paste. it is temporarily stable after UV curing, and the product changes color after and being placed for a period of time;

 

2. The нерівномірний розподіл of the гальванічне покриття шар of the product, that is, the товщина of the гальванічне покриття шар is uneven, resulting in different metal reflections in different areas, and yellowing where the гальванічне покриття шар is thin;

 

3. The UV curing effect of the topcoat is not good, and the UV exposure is insufficient, which leads to the curing of the UV surface layer. Part of the coating below the surface layer is not completely dry, and it reacts with the metal coating, resulting in the final discoloration of the electroplating product;

 

4. Excessive UV exposure of the topcoat will also cause the unstable color concentrate or color paste to become lighter due to high temperature

Вакуум покриття вішалка тінь

 

1. The design of the hanger is unreasonable, and the distribution of power lines is uneven.

2. The гачок ноги on the вішалка are loose, and the conductivity is poor;

3. The вішалка гачок has an insulating layer, which is not peeled off and clean

4. The hanger has been put on hold for a long time, and the conductive touch surface of the hanger has impurities, which are not completely removed.

5. The touch resistance of each touch point of the hanger is large, so that the factual density on the surface of the product is too small, and the coating in the low density area is not bright

6. The покриття on the hook of the hanger is very thick, it is not protected in time, and the conductivity is poor;

7 The workers did not right handle the product hanging method during the operation

The solution for vacuum plating rose gold color is easy to fade:

 

1. Замінити колір концентрат або колір паста з стабільною функцією;

 

2. Зменшити щільність добуток в те вакуум гальванічне покриття піч, збільшення відстань між виробом і виробом, і add the довжина of the гальванічне покриття матеріал to improve the явище of of нерівномірне гальванічне покриття, товщина і тонкий;

 

3. Add UV energy or reduce UV energy, and adjust the distance between the product and the UV lamp to improve the UV exposure effect of the topcoat and prevent color discoloration due to under-drying or overexposure;

 

4. Switch to the the three-coat vacuum coating process, and change the original topcoating and coloring process to the the method of middle-coating plus coloring plus cover transparent UV topcoat to block the the message of alcohol (аромат) solvent eroding color;
