The bleaching methods are similar for mechanical pulp, but the goal is to make the fiber brighter.
Normally the content of mechanical pulps are below 10% and the amount of fillers in the range 5-25%.
The bleaching methods are similar for mechanical pulp in which the goal is to make the fibers brighter.
Although large amounts of electrical energy are required to produce mechanical pulp, it costs less than chemical pulp.
Paper recycling processes can use either chemical or mechanical pulp.
Paper made from mechanical pulp contains significant amounts of lignin, a major component in wood.
With almost twice the yield as chemical pulping, mechanical pulps is often cheaper.
It uses mechanical pulp which has a high yield.
Chemical pulp is used for materials that need to be stronger or combined with mechanical pulps to give a product different characteristics.
These are uncoated and based on mechanical pulp.
