南方育果袋纸的开发与应用

Development & Production of Southern Fruit Cultivation Bag Paper

从原料结构、湿强剂的使用、生产工艺控制、产品质量要求、产品检测方法等方面,阐述了南方育果袋纸的技术开发和生产应用。研究与生产实践表明,湿强剂用量控制在2.0%以内较为理想;在生产育果袋纸的浆料中配用一定量的废纸浆能提高育果袋纸的透气度,降低生产成本;湿强剂加入点的选择直接影响产品的湿强度和生产成本;采用高浓低浓盘磨串联打浆有助于提高育果袋纸质量;采用生产快速检测方法检测育果袋纸的湿强度,可以满足生产及产品质量控制要求。

This paper describes the technical development and production of southern fruit cultivation bag paper in respect of raw material structure, the usage of wet strength agent, production technology control and test method of product quality, etc. Research and production practices indicate that the dosage of wet strength agent within 2.0% is suitable; adding some recycled pulp to the pulp for manufacturing fruit cultivation bag paper will improve the product's air permeance and reduce the production cost; the adding point of wet strength agent will directly affect the wet strength of the product and the cost. High-low consistency cascade refining improves the quality of fruit cultivation bag paper. Rapid wet strength test method of fruit cultivation bag paper can be applied for production and quality control.
