在房屋裝修過(guò)程中使用的脲醛樹(shù)脂膠，其主要的原料包括甲醛、尿素以及膠得寶。1、當(dāng)甲醛的濃度達(dá)到60～120mg/m3時(shí)，可能會(huì)引發(fā)支氣管炎和嚴(yán)重的肺部損害。2、吸入12～24mg/m3的甲醛會(huì)導(dǎo)致鼻腔和咽喉黏膜的嚴(yán)重灼傷，以及流淚和咳嗽等癥狀；若經(jīng)口攝入10～20mL的甲醛，可能會(huì)導(dǎo)致死亡。高濃度的甲醛 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.
