Problems solved by technology

[0004] The existing ceramic fiber paper has relatively poor strength performance and can only be used in the production of dehumidification rotors in ordinary rotary dehumidifiers. If it is directly applied to the production of ultra-low and ultra-low dew point dehumidification rotors, it will result in The expected dehumidification effect cannot be achieved in the dew point rotary dehumidifier, and its use time is short, resulting in waste of resources

Abstract

The invention discloses composite ceramic fiber paper for ultralow dew point desiccant wheel manufacturing. An upper paper layer, a binding layer, a fiber layer I, a binding layer, a fiber layer II, a binding layer and a lower paper layer of the fiber paper are stacked in sequence from top to bottom. The binding layers comprise, by mass, 0-50% of polypropylene and 50-100% of polyethylene. The fiber layer I comprises, by mass, 30-45% of ceramic fiber, 20-35% of mixed pulp, 10-20% of additive fiber, 5-25% of colloidal alumina, 5-15% of fire retardant and 5-10% of sizing agent. The fiber layer II comprises, by mass, 30-45% of ceramic fiber, 20-35% of wood fiber, 10-20% of additive fiber, 5-25% of colloidal alumina, 5-15% of fire retardant and 5-10% of sizing agent. According to the composite ceramic fiber paper, the original processability of the paper is maintained, the tensile strength, anti-aging performance, low temperature resistance and friction resistance of the paper are improved, ultralow dew point desiccant wheel manufacturing requirements are met, and the service life and efficiency of a desiccant wheel are improved.

Description

technical field [0001] The invention relates to a manufacturing process of an ultra-low dew point dehumidification rotor, in particular to a composite ceramic fiber paper used for the manufacture of an ultra-low dew point dehumidification rotor. Background technique [0002] Ceramic materials are a class of inorganic non-metallic materials made of natural or synthetic compounds through shaping and high-temperature sintering. It has the advantages of high melting point, high hardness, high wear resistance and oxidation resistance. It can be used as structural material, tool material, and because ceramics also have some special properties, they can also be used as functional materials. All over the world, the development of new ceramic materials and the functions of ceramic materials is a current research hotspot. [0003] Ceramic fiber paper is also the raw material for the dehumidification rotor in the rotary dehumidifier. The rotary dehumidifier is often used in undergrou...
