在房屋装修过程中使用的脲醛树脂胶，其主要的原料包括甲醛、尿素以及胶得宝。1、当甲醛的浓度达到60～120mg/m³时，可能会引发支气管炎和严重的肺部损害。2、吸入12～24mg/m³的甲醛会导致鼻腔和咽喉黏膜的严重灼伤，以及流泪和咳嗽等症状；若经口摄入10～20mL的甲醛，可能会导致死亡。高浓度的甲醛 exposure can cause acute poisoning, manifested as burning sensation in the throat, difficulty breathing, pulmonary edema, allergic purpura, allergic dermatitis, elevated liver transaminases, jaundice, and other symptoms. Extension information: 1. Uracil-formaldehyde resins are produced by adding GD-board and adjusting the pH to 7-7.5 after acidification. This new technology utilizing roller collision method results in uracil-formaldehyde glues with good performance indicators, lower production costs, and reduced free formaldehyde content. 2. The new technology for manufacturing uracil-formaldehyde glues is simple, convenient to use, cost-effective, and exhibits good performance. It has become the main type of glue used in China's particleboard production, accounting for more than 90% of the total adhesive used in particleboard. 3. Formaldehyde can also be found in other aspects of life: 1) Cosmetics, cleansers, insecticides, disinfectants, preservatives, printing inks, and paper. 2) Foam boards used as thermal, insulating, and cold-proof materials in construction can release formaldehyde when exposed to light and heat as they age and degrade, producing off-gas substances. 3) Formaldehyde can also be emitted from automotive seat covers, cushions, and car roof liners, with new vehicles showing the most prominent formaldehyde release.
