The main reason for applying nanotechnology solutions is added value. Nanotechnology in papermaking can be applied in several areas. These include:
- Water based coatings that are non-toxic, smoother and tougher
- Surfaces that are smoother and have better printability
- Enhanced sheet properties by adding nanoparticles such as silica
- Developing grades that are stronger and lighter, use less fibre and are biodegradable
- Closed looped water reuse with nano-filtration
In traditional paper making, nano-particle-based fillers, substituting for fibre, and combined with lower basis weights, are delivering significant savings to the industry. Also, wet end retention aids are another example of existing nanotechnology. Click to continue »
