A microporous medical packaging paper surface drying device

Abstract

The invention discloses a micro-aperture medical packaging paper surface drying device, which uses coniferous wood and broad-leaved wood as main raw materials, and the fiber ratio of leafy wood and broad-leaved wood is 75%-85% for coniferous wood and 15% for broad-leaved wood. %‑25%, and then separately beat the coniferous wood and hardwood raw materials, and analyze the microstructure of paper and raw materials through imported scanning electron microscopes in time, and then perform surface sizing and drying operations. This invention adopts new technology In-depth analysis and research on products and raw materials in the research process, the introduction of advanced imported scanning electron microscopes, through the microstructure analysis of paper, raw materials, etc., and the determination of paper porosity and other means to study fiber selection, the hardwood fiber The dosage has been increased by 6%-10%, thereby improving the uniformity of the pore size distribution of the dialysis paper. The cumulative distribution of the 0.23μm-3.2μm pore size range is more than 90%, and the maximum pore size does not exceed 5.0μm, which can effectively block the penetration of bacteria.

Description

technical field [0001] The invention relates to the technical field of production and processing of medical packaging paper, in particular to a surface drying device for micro-aperture medical packaging paper. Background technique [0002] During the production and processing of medical packaging paper, the paper needs to be dried. At present, it is generally spread out to dry in the air, or the paper is transferred from one drum to another and dried during the transfer process. , but the drying process of the first drying method is slow, and the second drying method consumes a lot of heat, and the drying efficiency is low. Therefore, we propose a microporous medical packaging paper surface drying device. Contents of the invention [0003] The purpose of the present invention is to provide a microporous medical packaging paper surface drying device to solve the problems raised in the above-mentioned background technology. [0004] In order to achieve the above object, the...
