Method for preparing fibre humidity-controlling board and apparatus

Abstract

The invention provides a method for making a fiber humidity-adjusting board and equipment thereof. The fiber humidity-adjusting board comprise fiber materials, inorganic material or inorganic and organic materials mixing humidity-adjusting agent and adsorption particles, among which fiber materials are taken as the base material component; the method comprise the following steps that: hydrophilic fiber materials are made into water dispersion; the water dispersion is drained on a web plate, and solid adsorption particles are dispersed in the water dispersion, and the water dispersion is dewatered and turned into fiberboard base materials; the fiberboard base materials are soaked in drying fluids; after drying, forming plates or splinter-shaped products are obtained. The humidity-adjusting board has the advantages that because the fiber humidity-adjusting board is splinter-shaped, the fiber humidity-adjusting board can be cut into different shapes; the fiber humidity-adjusting board has the function of adjusting the humidity and reaches and exceeds international seminal humidity-adjusting products in wet volume capacity; nontoxic, harmless and recyclable materials are used; due to the adoption of closed cycle process, no waste gas, waste water and waste slag are generated and discharged, so that the fiber humidity-adjusting board is new-generation green environment friendly product; due to the adoption of the environmental protection process, no waste gas, waste water and waste slag are discharged, and all added solids are not drained, so that the controllability is good.

Description

technical field [0001] The invention relates to a manufacturing method and equipment for a fiber humidity-regulating board, and relates to a production process of a desiccant capable of regulating humidity and production equipment suitable for manufacturing the desiccant. The fiber humidity control board belongs to a product used to control the humidity range of a relatively closed space. It is a "high-precision" desiccant. It not only adjusts the humidity through moisture absorption and drying, but also balances the humidity through humidification. Background technique [0002] With economic development, improvement of people's living standards and global warming, it is estimated that the global desiccant consumption will grow at a rate of about 3% per year. Globally, the desiccant market is sizable in high-humidity regions. In tropical and subtropical regions, the rainy season is long, the air humidity is high, and the consumption of desiccant is large. For example, the a...

Problems solved by technology

[0027] In recent decades, the research and application of humidity control materials have developed rapidly, but they are still not satisfactory, either because of poor moisture absorption and desorption properties, or limited moisture absorption and desorption, and the application in cultural relics protection is even worse. Restricted by the standard that the humidity conditioner itself must be harmless to cultural relics

At present, the global market lacks high-performance environment-friendly humidity control products. How to develop a safe, harmless, non-polluting, energy-saving humidity control agent for cultural relics protection, in order to achieve better humidity control characteristics and low cost is an urgent need to solve At the same time, how to solve the problem that the product design does not match the existing equipment is also the key to the product design concept
