| titleOfInvention | A kind of formaldehyde purifying agent and preparation process thereof |
| abstract | The invention relates to the field of preparation of formaldehyde purifiers, in particular to a formaldehyde purifier and a preparation process thereof. The invention can purify formaldehyde; the formaldehyde purifier comprises tourmaline powder 30%-50% and adsorption materials 30%-50% by weight. 50% and 10%-20% of the catalyst; the process includes the following steps: S1, taking tourmaline for cleaning through a cleaning device, and performing ball milling after constant temperature pretreatment to obtain tourmaline powder; S2, taking the adsorption material and mixing it with water, and slowly adding acid The solution is washed with water and dried to obtain an acidified adsorbent; S3, respectively mixing potassium permanganate, manganese sulfate, and sodium hydroxide with water to obtain an aqueous solution of potassium permanganate, an aqueous solution of manganese sulfate, and an aqueous solution of sodium hydroxide S4, the potassium permanganate aqueous solution, the manganese sulfate aqueous solution and the sodium hydroxide aqueous solution are mixed and reacted simultaneously, and after the reaction is dried, the catalyst solid powder is obtained; S5, the tourmaline powder, the acidified adsorbent and the catalytic solid powder are mixed uniformly , that is, the air purification material is obtained. |
