The paper introduces the functions of phosphate surfactant and the composite test on the phosphate oil agent 摘要概述了磷酸酯類表面活性劑的作用,詳細論述了磷酸酯油劑(代號517 (上標# ) )的合成小試研究工作。
Abstract : based on composite testing of naphthalene superplasticizer and different retarders as well as retarding water reducer , in which the overall amount of admixture is certain , this paper analyzes the influence of these multicomponent admixtures on flowability of neat cement 、 retarding action and development of strength of colloidal mortar . the result shows that compatibilities of different components are different , and composition effects are also different 文摘:在總摻量一定的情況下,就萘磺酸鹽高效減水劑與不同緩凝組分、緩凝型減水劑等復合后對水泥凈漿流動度、緩凝作用、膠砂強度發(fā)展等性能的影響作用進行了試驗分析,結果表明各不同組份復合的相容性不同,復合效應也存在差別。
And another brake material formula also can be achieved in which the carbon fiber was replaced by the wood fiber based on the researching of the effect of fibre , resin and filler in multi - fibres hybrid composite test result shows that the formula material have a relatively suitable friction coefficient ( ranging around 0 . 35 ) , good fade resistance and recovery as well as low wear ratio . by comparing the formula material with the product of national and abroad sold in the market , its low cost and excellent properties make a bright prospect 在研究各種纖維、樹脂和填料對混雜纖維復合摩擦材料摩擦學性能影響的基礎上,本文研制開發(fā)出分別適用于中重型車與中小型車用的剎車摩擦材料的最佳配方和一種含木纖維的多種纖維混雜復合摩擦材料的最佳配方。將所選配方的剎車材料與市售的國內(nèi)外品牌剎車片進行對比,結果表明本課題所開發(fā)研制的摩擦材料的摩擦系數(shù)都在0 . 35左右,具有很好的摩擦系數(shù)穩(wěn)定性和抗熱衰退性,磨損率也較小,綜合考慮到配方試樣原料成本較低,在性價比上具有一定的優(yōu)勢。
