Problems with conventional systems
Heat damage caused during drying
Hot air drying causes large heat damage to films or applied materials, and cannot be used with materials that are susceptible to the effects of heat.
Drying inside the product
Because a vacuum system is used to remove moisture from inside the product, this has adverse effects on productivity and cost.
Drying of thick film products
Webbing and foaming occurs on the surface of thick applied materials, making uniform drying difficult.
New idea from NGK
- PI base material ⇒ Changed to PET base material
- Continuous drying at atmospheric pressure
- Drying of 300μm or larger thick films
Expected benefits from the wavelength-control system (main benefits)
1. Low-temperature drying
Can dry solvents while reducing heat damage to the components or resin base material.
2. Internal drying
Can dry the remaining moisture inside the products.
3. Drying of thick films
Prevents webbing of the surface and promotes drying on the inside of thick films, a location that cannot be dried by hot air.
In addition, benefits such as the following can also be expected.
- Reduced drying time: Approx. 1/2 to 1/3
- Reduced power consumption: 30 – 50% reduction
- Reduced binder segregation: 30 – 40% reduction is possible.
- ※All coparisons are with hot air.
