Los productos moldeados por inyecci\u00f3n<\/a> pueden cambiar de color debido a varios factores:<\/p>\n\n

<\/div>\n\n

Razones de la decoloraci\u00f3n de los productos de pl\u00e1stico:<\/h2>\n\n
<\/div>\n\n

1. Pl\u00e1stico y pigmento mezclados con escombros;<\/p>\n\n

2. Contaminaci\u00f3n o degradaci\u00f3n de pl\u00e1sticos y pigmentos, descomposici\u00f3n;<\/p>\n\n

3. La calidad del pigmento no es buena o la mezcla no es uniforme cuando se utiliza;<\/p>\n\n

4. La temperatura del ca\u00f1\u00f3n y la boquilla es demasiado alta, lo que hace que el material de<\/a> goma se queme y se decolore;<\/p>\n\n

5. La presi\u00f3n y la velocidad de inyecci\u00f3n son demasiado altas, lo que provoca la descomposici\u00f3n de los aditivos y colorantes;<\/p>\n\n

6. Humedad de la superficie del moho<\/a>, aceite o uso excesivo de desmoldeante;<\/p>\n\n

7. Distribuci\u00f3n desigual de rellenos de fibra, productos y p\u00e9rdida de resina por contacto con disolvente, de modo que la fibra queda desnuda;<\/p>\n\n

8. Hay obst\u00e1culos en el tubo de fusi\u00f3n que favorecen la degradaci\u00f3n del material.<\/p>\n\n

Soluci\u00f3n para la decoloraci\u00f3n de productos pl\u00e1sticos:<\/h2>\n\n
<\/div>\n\n

1. Evite mezclar con escombros al mezclar;<\/p>\n\n

2. Las materias primas deben estar secas, el equipo debe estar limpio y el repostaje debe limpiarse para evitar que queden materiales sobrantes;<\/p>\n\n

3. Para garantizar la calidad de todos los pigmentos, \u00e9stos deben adherirse uniformemente a la superficie de las part\u00edculas al mezclarse;<\/p>\n\n

4. Reduzca la temperatura del tubo de fusi\u00f3n y de la boquilla para eliminar el material de cola quemado.<\/p>\n\n

5. Reducir los valores de los par\u00e1metros de presi\u00f3n y velocidad de inyecci\u00f3n para evitar la descomposici\u00f3n de los aditivos;<\/p>\n\n

6. Secar la superficie del molde con agua y aceite, uso racional de desmoldeante;<\/p>\n\n

7. Establezca los par\u00e1metros de proceso del relleno de fibra razonablemente, utilice el disolvente razonablemente, haga que la plastificaci\u00f3n sea buena y elimine la exposici\u00f3n de la fibra;<\/p>\n\n

8. Preste atenci\u00f3n a la eliminaci\u00f3n de obst\u00e1culos, especialmente para el repostaje, para seguir estrictamente el procedimiento de paso o utilizar el m\u00e9todo de repostaje de transici\u00f3n.<\/p>\n","protected":false},"excerpt":{"rendered":"
