可降解椰壳纤维格室的研究开发

Research and development of degradable coconut fiber cell

探讨可降解椰壳纤维格室的研究开发过程。介绍了椰壳纤维针刺非织造工艺流程以及生产中采取的主要工艺措施。阐述了椰壳纤维格室的超声波焊接技术。对椰壳纤维格室的物理性能指标进行了测试及分析。结果显示:椰壳纤维格室吸水率适中、保水率小、孔隙率大,30 min内芯吸高度为0;透水性好,水及营养剂可在格室间自然流动。椰壳纤维非织造布纵横向断裂强力、撕破强力较低,植物根系发育成形后可在格室中自由伸展,植株间自然交联。椰壳纤维分解后转化为植物的营养基质,可改善土质,利于植物生长。

Research and development of biodegradable coir fiber geo-cell are discussed. Needle-punched nonwoven process and main technological measures in production are introduced. The ultrasonic welding technology is expounded. Through physical performance test and analysis, it is found that the coir fiber geo-cell has moderate water absorption, low water retention, large porosity and wicking height of 0 within 30min, and has good water permeability, which enables water and nutrients to flow among the geo-cell, and features low tear strength, low vertical and horizontal tensile strength, which enables plant root to stretch freely to be cross-linked. The biodegraded coil fiber can be converted into plant nutrient substrate, so as to improve soil quality to benefit to the plant growth.
