1973～1974年,我局设计研究院科研所试验研究成功混凝土减水剂NNO。经广泛应用于港口建设、水利工程、冶金建筑、化工建筑和民用建筑中,效果良好。在此基础上,1976年上半年至1977年,又进一步研制多萘核磺酸盐(DNS)混凝土减水剂,得到武汉化学助剂厂积极配合协助,作了中间试验,初步取得成功。 DNS混凝土减水剂,是萘磺酸盐甲醛高
From 1973 to 1974, the research institute of the Institute of Design and Research of our bureau experimented and succeeded in the research and development of NNO, a concrete water reducer. It has been widely used in port construction, water conservancy projects, metallurgy construction, chemical construction, and civil construction. Based on this, in the first half of 1976 to 1977, it further developed the multi-naphthalene sulfonate (DNS) concrete water-reducing agent, which was actively assisted by Wuhan Chemical Auxiliary Factory and made an intermediate test. The initial success was achieved. DNS concrete water reducer is naphthalene sulfonate formaldehyde high
