Semi-mechanical pulping is also called semi chemical pulping or hybrid pulping Mechanical pulping involves reducing a tree to individual fibres using only mechanical methods, such as a grindstone or efiner. No chemicals are used Chemical pulping involves reducing a tree to individual fibres using only chemicals at high temperatures and pressure. No mechanical methods are used. The chemicals dissolve the lignin that glues the fibres together. Seemi-mechanical pulping involves treating wood chips with chemicals to remove/destroy some of the lignin, THEN, putting the material through a refiner to break up the remaining fibre clumps
thank you sir
Thanks helped me understand the process and the outcome.
Great content
What is generally the main equipment machines used in mechanical pulping? Can you make some introduction to those machines?
What is semi -mechanical pulping??
