Efforts of Microwave and Infrared Radiation in Chemical Pulping pay off

Pulping is a procedure that separates fibrous material and cellulose from wood or other crude material as a prelude to papermaking. The reason for pulping is to free cellulose strands from other chemicals and polluting influences in the wood (or different fibrous source). Before wood can be pulped, it must experience debarking i.e. expelling bark mechanically or hydraulically and then sending the debarked wood into a chipper to cut them into small pieces ready for pulping. Pulping can be done by three processes –

  1. Mechanical – Using machines like revolving disks to prepare the pulp for paper making.
  2. Chemical – wood chips are cooked in a combination of chemical solution to remove cellulose or lignin from the wood.
  3. Semi-mechanical – a blend of mechanical and chemical.

Here we understand the process of Chemical Pulping in detail. As known it is a method of converting the wooden chips into damp pulp for paper making or processing, by cooking the wooden chips in a chemical solution to extract lignin or cellulose content which is primarily responsible for reducing paper quality and permanence. Chemical Pulping has two primary methods of processing –

  • The Sulfite process: cooks wood chips in sulfurous acid combined with limestone to produce calcium bi-sulfite. The combination of sulfurous acid and calcium bi-sulfite dissolves the lignin in the wood and liberates the cellulose fibers. Sulfite pulp is soft and flexible, is moderately strong, and is used to supplement mechanical pulps.
  • The Sulfate Process: evolved from the soda processes developed in the nineteenth century using strong bases to digest wood. Pulpers began adding sodium sulfate (correctly known as sodium sulfide) to the soda process and a significantly stronger pulp was produced. This process is more accurately known as the Kraft process (after the German word meaning ‘strength’)

Advantages of Chemical Pulping in production of paper:

  • Stronger fibre in paper
  • Highest quality printing and writing papers
  • Fewer impurities
  • Wastages can be used as fuel
  • Brighter papers produced

KERONE has always been the decision of various clients for its broad ‘hands-on’ involvement of use of microwave and infrared in the paper processing industry.
