Problems solved by technology

Most of the existing formaldehyde removal products are activated carbon substances. After the activated carbon absorbs formaldehyde, it needs to be exposed to the sun, otherwise the formaldehyde will be released again, causing secondary pollution

Abstract

The invention discloses a production process of a novel formaldehyde removal material, which comprises the following steps: weighing the following raw materials in percentage by weight: 10-30% of water, 4-12% of potassium permanganate and 58-86% of composite aluminum oxide; preparing a potassium permanganate solution, mixing and stirring potassium permanganate and water in a container to obtain a solution A at the water temperature of 80 DEG C, and uniformly mixing; filtering the solution A through a multi-layer vibrating screen device to obtain a solution B, adding composite aluminum oxide into the filtered solution B, and uniformly stirring for 30-60 minutes; and pouring the mixture into a temperature-controllable timed overturning container for overturning to obtain the novel formaldehyde removal material, and packaging to obtain a finished product. According to the novel formaldehyde removal material, whether a formaldehyde removal product fails or not can be distinguished according to the oxidation effect; the oxidation time is long, and the effect is much higher than that of activated carbon; multiple targets are achieved, formaldehyde removal can be observed through color changing, the color can be recognized by naked eyes, and a plurality of harmful substances such as TVOC after decoration can be removed; and harmful substances can be continuously oxidized, and secondary pollution is avoided.

Description

technical field [0001] The invention relates to the technical field of air purification material production, in particular to a production process of a novel formaldehyde-removing material. Background technique [0002] With the improvement of people's living standards, while paying more and more attention to the quality of life, they pay more attention to environmental protection and health. Decoration materials often contain harmful substances such as formaldehyde. The main hazard of formaldehyde is the stimulation of skin and mucous membranes. When formaldehyde reaches a certain concentration indoors, people will feel uncomfortable. Formaldehyde concentrations greater than 0.08mC can cause red eyes, itchy eyes, throat discomfort or pain, hoarseness, sneezing, chest tightness, asthma, dermatitis, etc. Newly decorated rooms have higher levels of formaldehyde, which is the main cause of many diseases. [0003] The release cycle of formaldehyde is as long as 15 years, and f...
