Comparison of Chemical Pulping and Mechanical Pulping

There are some differences between the two types of pulp. Mechanical Pulp In the production of mechanical pulp, goldare ground against a water-lubricated rotating stone. During this process, the heat generated by grinding softens the lignin-containing fibers, and the mechanized forces separate the fibers to form the ground we want.
