Pulp

Pulp is the result of the separation of fibers from fibrous raw materials (wood and non wood) through various manufacturing processes (mechanical, semikimia, Chemistry).

Pulp consists of Fiber - Fiber (cellulose cheap hemicellulose) as raw material for paper.



The process of making pulp of which made ​​the process of mechanical WITH, Chemical, cheap semikimia. Preparation of mechanical pulps principle that is eroding WITH THE TOOL uses such as grinding. The mechanical process commonly known of which PGW (Pine groundwood), SGW (Semi groundwood). Semi-chemical process is a combination of inexpensive chemical mechanical BETWEEN. Including the Inward, this process can not include CTMP (Chemi Thermo Mechanical pulping) WITH degrade lignin utilizing temperature TO in order to obtain the pulp has a low yield of the More Good quality More than a mechanical process WITH pulp.

Chemical pulping processes known as WITH THE kraft process. Called kraft pulp BECAUSE A From this process has produced a Higher Power than the mechanical process semikimia cheap, but the yield of the Smaller Components resulting in both BECAUSE OF A LOT more degraded (lignin, extractives, cheap minerals)
