Bleaching Chemical Mechanical Pulping System
Descriptions:
CNBM Bleaching chemical mechanical pulping employs a combination of chemical pretreatment and mechanical refining. Initially, a mild chemical treatment (such as impregnation or cooking) is applied to remove a portion of hemicellulose and a small amount of lignin is either dissolved or remains largely intact, which softens the middle lamella. The softened chips are then processed in a refiner to separate the fibers into pulp.
The development of high-yield chemical mechanical pulping is significant for several reasons: it allows for the efficient and rational utilization of plant fiber resources, reduces pollutants in pulping wastewater, and meets product performance requirements.
