By testing according to correlation criterions , the performances of jd such as ratio of water - reducing , ratio of compressive strcngth , effect of accelerating and enhancing strength , ratio of bleeding , air entrainment content , effect of keeping slump value , compatibility with cement , resistance to concrete shrinkage and damage by freezing and thawing and water - tightness etc are all better than that of the traditional melamine resin superplasticizer sm and naphthalene series superplasticizer fdn 按照相關標準進行測試,所開發的改性密胺樹脂高效減水劑的各種性能如減水率、抗壓強度比、早強增強效果、泌水率、引氣性、坍落度保持效果、與水泥適應性、收縮性能、抗凍融性能、抗滲性能等都遠遠優于傳統的三聚氰胺高效減水劑sm ,也優于萘系高效減水劑fdn 。

The synthesizing process can be finished in a single kettle . not only technology is very simple , but also the reaction time is shortened , therefore , the production efficiency is obviously increased . the general performances of modified melamine resin superplasticizer jd can be furthermore improved by compounding amino - arylsulphonate phenol formaldehyde condensate superplasticizer hpp 使用廉價的活性單體尿素取代三聚氰胺單體以降低高效減水劑的生產成本,并將取代量提高到了目前最高水平17 ;合成在一個反應釜中完成,工藝簡單,反應時間縮短,提高了生產效率;本文通過物理改性的手段,即復配氨基磺酸鹽高效減水劑hpp ,可進一步改善改性密胺樹脂高效減水劑的綜合性能。

In japan , an amendment law on construction standards has been implemented , which is stipulated that the products containing formaldehyde should not be used indoors , including urea - formaldehyde resin , melamine resin and resorcinol resin 日本已開始實施建筑標準法修正案,規定室內不允許使用含甲醛系列防腐劑的脲醛樹脂、三聚氰胺樹脂和間苯二酚樹脂等產品。

When the content of nano - silica reached 1 . 0 % , the waterproofing coatings had the best performance . the organic - mmt and melamine resin compound modification and the organic - mmt and organic nano - sio2 compound modification were studied 還研究制備了有機蒙脫土和交聯劑復合及有機蒙脫土和接枝處理納米sio _ 2復合改性聚合物水泥基防水涂料。

The parameters of synthesizing technology of traditional melamine resin superplasticizer were optimized , and the distinct parameters were ascertained through the perpendicular experiments 以正交試驗為基礎優化了傳統密胺樹脂高效減水劑的合成工藝參數,找出了顯著影響因素。

The mechanical properties and the resistance to water and heat of the polymer modified cement based waterproofing coating are greatly improved by the synthesized melamine resin 三聚氰胺甲醛樹脂交聯劑可明顯改善聚合物水泥基涂料的力學性能、耐熱性能和耐水性能。

By controlling those parameters , the hydroxymethylated and sulfonated ratios of melamine resin superplasticizer were enhanced , the performances of product also improved 通過控制這些因素提高了密胺樹脂高效減水劑的羥甲基化率和磺化率,改善了產物性能。
