Such methods as compounding retardants, compounding water - reducing agents ( which has various the extent of condensation ), changing the ways of addition and retardarce method, are used to impolder new water - reducing agent and construction method to salve slump loss, but it can not work drastically
通過復合緩凝組分、不同縮合度減水劑的復合、改變摻加方式、緩釋法等技術路線開發新型減水劑和施工方法來解決坍落度損失問題，但是這一問題並沒有得到根本解決。 -
Using water - soluble carbodiimide as condensation agent, biomacromolecules such as gelatin, collagen and chitosan were covalently grafted on the plla - g - pmaa membranes. solution of the biomacromolecules was further coated on the above membranes to increase the surface density of the biomacromolecules. this technology was designated " grafting and coating " method
為了將生物大分子化學接枝于plla膜表面，首先在plla膜表面接枝pmaa ，將羧基引入plla表面，利用水溶性碳化二亞胺edac作為縮合劑，與含有氨基的生物大分子反應，可將生物大分子如明膠、膠原和殼聚糖化學接枝在plla膜表面。 -
Abstract : the basic synthesis process parameters of water reducing agent of melamune series was studied. the factors affecting hydroxymethylation, stlfonation, low - ph condensation, and high - ph condensation were thoroughly studied. from that, the good conditions for every stages were determined. by addition of compound additives made of some cheap components, the production cost of melamine water reducing agent was greatly decreased so that the spread and application value was increased
文摘:研究了三聚氰胺系列減水劑的基本合成工藝，考察了各種因素對羥甲基化階段、磺化階段、縮聚階段的影響，確定了各階段的最佳工藝條件，通過加入一些廉價組分製成復合型減水劑，使得三聚氰胺系列減水劑的生產成本大幅度降低，提高了產品的推廣應用價值
