Problems solved by technology

Natural antibacterial materials are mainly derived from animals and plants. They have good biocompatibility, less pollution to the environment, and less toxicity. However, the sources are limited, the extraction cost is high, and the stability of the extract is relatively poor, so they cannot be used in runners. And its adsorption materials; organic antibacterial materials can be divided into low-molecular antibacterial materials and hi

Abstract

The invention relates to the technical field of rotating wheel preparation, in particular to an antibacterial household dehumidifying rotating wheel and a preparation method thereof.The preparation method comprises the steps that an inorganic fiber rotating wheel is pretreated, impregnated with a silicon source at the room temperature, dried and then impregnated in acid liquor for a water bath reaction; drying and roasting after washing to be neutral; dipping into an active agent, washing and drying; and soaking in a metal salt solution for reaction, soaking in a reduction reaction solution for water bath reaction after the reaction is finished, and washing and drying to obtain the antibacterial household dehumidifying rotating wheel. The prepared antibacterial household dehumidification rotating wheel comprises the metal particle-silica gel composite material, the antibacterial property can be effectively generated, the texture property of the material is improved, the water absorption capacity is increased, and the dehumidification performance of the rotating wheel is improved.

Description

technical field [0001] The invention relates to the technical field of runner preparation, in particular to an antibacterial household dehumidification runner and a preparation method thereof. Background technique [0002] Rotary dehumidification systems are widely used due to their advantages of energy saving, large dehumidification capacity, high efficiency and continuous provision of low dew point dry air. Among them, the dehumidification rotor is the heart of the system, and the adsorbent material loaded on the dehumidification rotor is extremely critical. At present, the commonly used adsorption materials for dehumidification rotors include lithium chloride, molecular sieves, silica gel and metal ion-doped silica gel, etc. Because silica gel has good stability in the adsorption process, is easy to clean, easy to control the pore size, and the regeneration temperature is relatively low, so it is widely used at home. The dehumidification industry has attracted much atten...
