降失水劑 的英文怎麼說
中文拼音 [jiàngshīshuǐjì]
降失水劑
英文
fluid lo agent/additive， filtration reducer-
The new high effective water - reducing agent act - fdn has characteristic of reactivity, it ca n ' t dissolve in water but do in alklia. in the concrete, it decompounds slowly and gives out sulfonate group which has dispersity, this can make the high effective water - reducing agent available for a long time, therefore it can reduce slump loss
研製的新型高效減水劑act - fdn ，具有反應性的特點，不溶於水但溶於堿，在混凝土這樣的堿性環境下可以緩慢分解釋放出具有分散性能的陰離子磺酸基，使高效減水劑能夠持久發揮作用，從而達到了降低坍落度損失的目的。The study results indicated that, arranged in the order of magnitude, the degrees of the effects on the cementing strengths of the two interfaces were the system, emulsion, main emulsifier, fluid loss control agent and white oil respectively ; the cementing strength would be doubled and redoubled after being cleaned by preflush, especially by the system, emulsion and fluid loss control agent ; and, along with the increase in the mix slurry ratio, the initial and final set times of slurry would be obviously lengthened and the compressive strength of bond cement would be remarkably reduced or the slurry wouldn ' t be even set
研究表明：對兩界面膠結強度的影響由大到小依次是體系、乳狀液、主乳化劑、降濾失劑、白油；前置液清洗后，膠結強度成倍提高，尤其對體系、乳狀液和降濾失劑清洗效果最佳；隨混漿比的增大，水泥漿初凝和終凝時間明顯延長，水泥石抗壓強度明顯下降，甚至不凝。2 use the xcd polymer as the viscosifier and fluid loss additives in mud
