Description

Medical dialysis base paper forming net

Technical Field

The utility model relates to a forming net technical field especially relates to a medical dialysis body paper forming net.

Background

During the papermaking process, about 95% of the water content of the pulp is removed through the papermaking forming wire: the paper making forming net is contacted with dewatering elements such as a breast roll, a forming plate, a low vacuum suction box, a high vacuum suction box, a couch roll and the like in the operation process, so that the paper making forming net is an indispensable expensive dewatering device for paper making enterprises, a good paper making forming net must meet the paper making quality requirement, longer service life and good operation stability, the factors such as fiber support index, air permeability, drainability, longitudinal and transverse stability, stiffness, service life and the like of the forming net are comprehensively considered in the structural design of the forming net so as to achieve optimization, at present, the paper making forming net is gradually developed to a polyester three-layer net series product as a main factor, the use of a modern high-speed and wide paper making machine can be basically met, the domestic paper making net blanket enterprises introduce foreign advanced technologies and increase the investment in research and development of new technologies, the paper making forming net technology of China gradually catches up with the international advanced level, gradually replacing an imported papermaking polyester forming net; compared with the traditional forming net, the three-layer polyester forming net greatly improves the service life and the paper quality, but the service life is mostly maintained between 20 and 60 days, the limit of the service life of the forming net increases the shutdown times of a paper machine, the production cost is increased, and the production efficiency is reduced, so the performance of the three-layer polyester forming net for improving the paper-making forming net, particularly a high-speed paper machine, has very important economic and social benefits, and the polyester forming net is broken under tension after being worn to a certain degree, and researches show that the wear of the polyester forming net has two aspects: abrasion caused by contact friction between the forming net and a roller in the running process of the forming net is different, and the influence of different fillers added into paper pulp is also different; the impact of high-pressure water washing the net is to the abrasion of the net, and the cleanability of the forming net is improved by improving the anti-pollution performance of the forming net, and the forming net has an important function for reducing the washing damage of the high-pressure water to the net, and the surface of the polyester monofilament has hydrophobicity, so that hydrophobic substances such as resin and the like are easy to combine with the polyester net for precipitation and are difficult to clean, and therefore, the hydrophilicity of the forming net can be increased and the cleanability of the forming net can be improved by modifying the surface of the polyester forming net monofilament.
