Description

[0001] 【Technical field】 [0002] The invention belongs to the technical field of membrane material preparation, and in particular relates to a filter membrane prepared by 3D printing technology and a preparation method thereof. [0003] 【Background technique】 [0004] The main components of VOCs are: hydrocarbons, halogenated hydrocarbons, oxygen hydrocarbons and nitrogen hydrocarbons, which include: benzene series, organic chlorides, Freon series, organic ketones, amines, alcohols, ethers, esters, acids and petroleum hydrocarbon compounds Wait. VOCs is the English abbreviation of Volatile Organic Compounds, and the chemical substances (except heavy metals) in wall paints that are commonly referred to as harmful to the human body refer to VOCs. These volatile organic compounds include formaldehyde, ammonia, ethylene glycol, esters and other substances. When VOCs in the room reach a certain concentration, it will cause symptoms such as headache, nausea, vomiting, fatigue, etc...
