本刊讯研究性能良好而又无毒无污染的新型钢筋防腐剂是当前我国发展加气混凝土迫切需要解决的一个课题。目前加气混凝土生产中采用的沥青—酚醛树脂钢筋防腐剂,因为采用苯酚和甲醛为原料,带来环境污染问题,蒸压釜冷凝水中含酚量最高时达100毫克/升,大大超过国家规定的污水排放标准。为此,根据国家建材总局下达的科研任务,北京市建筑材料科研所、陕西省建筑科学研究所、河南建筑工程材料科学研究所、齐齐哈尔铁路局加气混凝土厂、西安硅酸盐制品厂等五个
It is a pressing task for the development of aerated concrete in China to study a new type of steel anticorrosive agent with good performance and no toxicity or pollution. At present, asphalt-phenolic resin reinforced anticorrosive used in the production of aerated concrete, because the use of phenol and formaldehyde as raw materials, brings about environmental pollution problems. The phenol content in the autoclave condensate water reaches 100 mg/liter, which greatly exceeds the national regulations. Sewage discharge standards. For this purpose, according to the scientific research tasks issued by the State Bureau of Building Materials, the Beijing Institute of Building Materials, the Institute of Construction Science of Shaanxi Province, the Institute of Materials Science and Engineering of Henan Province, the Qiqihar Railway Bureau’s aerated concrete plant, and Xi’an’s Silicate Products Plant, etc. One
