一种减少本色木浆黑纤维尘埃的方法
By combining mixed hardwoods with corn cobs and employing a dual-tube hot grinding process, the problem of high wet weight of traditional pure hardwood fibers has been solved, enabling the production of low-wet-weight wood fibers. This reduces costs and improves paper performance, making it suitable for the production needs of high-end lightweight boards.

AI Technical Summary
Traditional pure hardwood thermo-abrasive fiber typically has a wet weight of around 4-6, with coarse fibers and a strong tendency to flocculate. This limits the proportion that can be added to corrugated paper and recycled paper, easily leading to problems such as poor uniformity, slow dehydration, and high drying load. In addition, high-quality wood resources are scarce and the cost is high.
By combining mixed hardwood and corn cob in a specific ratio, and through pre-steaming treatment and double-horizontal tube thermal grinding and dissociation process, combined with dehydration and drying, the wet weight of the fiber is reduced to below 2.0g, black fiber dust is removed, and the fiber morphology and mechanical strength are optimized.
It significantly reduces the wet weight of wood fibers, improves fiber compatibility and addition amount, reduces production costs, improves paper performance, expands application areas, and achieves efficient resource utilization and environmental and economic benefits.
