Notch and groove were produced on fiber's surface by plasma's pHysical bump and corrasion, meanwhile oxygenic or nitrogenic radicals were also grafted on the surface. Through hydrolyzation, acetate fiber's surface will be denuded by cellulase enzyme. Surface of the fiber will be granulated and specific surface area will be enlarged by plasma and enzyme treatment, therefore obviously improve fiber's surface performance.
等离子体对纤维的物理撞击和表面刻蚀使纤维表面产生凹坑和沟槽,同时可在纤维材料表面引入含氧或含氮基团;而纤维素酶对纤维素的水解作用,促使纤维表面被剥蚀;等离子体与生物酶处理都能使纤维表面粗糙化,比表面积增加,使纤维的表面性能得到明显改善。

The fluffy film may fall off from Cf if the pretreat method of Cf suface was not appropriate. Boron sources was ahead loaded on the surface of Cf by in situ chemical reaction to protect the fiber from corrasion of vapor such as NH_3 and increase the combination between BN film and Cf. The measured surface area of the composite fiber increased greatly to
表面的氮化硼绒膜与碳纤维的结合程度,取决于碳纤维表面预处理的方式,先期在表面通过原位化学反应引入硼源物质,形成保护膜,可以避免碳纤维在整个反应过程中受到气相侵蚀而影响氮化硼绒膜与碳纤维的结合程度,该复合材料的比表面积大幅提高,达到96m~2/g。

As the sample of Yuanliangshan tunnel in Chongqing-Huaihua Railway, based on the full analysis of groundwater specimens, five chemical equations are designed to calculate evaluating data by the relation of activity, equilibrium constant and Gibbs free energy. According to the two criterion of partial pressure of carbon dioxide and reaction direction, the result calculated shows the groundwater has weak corrasion to carbonate rocks, which should be avoided to do harm to tunnel.
以渝怀线圆梁山隧道为实例,通过隧道内地下水取样进行了全分析,其中CO(上标 2-下标 3)离子作为"中间过渡态"离子,由于只存在微小量未被检出;使用水质分析结果数据设计了五个化学反应方程式,通过活度、反应平衡常数及吉布斯自由能之间关系进行热力学计算,依据二氧化碳气体分压P(下标 CO2)与反应进行两个方向化学反应判据开展分析,结果表明地下水具有弱侵蚀性,在隧道工程中应避免其引起危害。

The preventive measures for the harmful defects of alkali metals are as follows: 1, reducing the alkali metals content in the raw materials; 2, increasing the MgO content of the sinter , decreasing the basicity of slag , decreasing the Si content of the pig iron, increasing relative slag volume; 3 , introducing prereduced ore pellets or partly reducted sinter; 4increasing the ability of coke resisting alkali metals; 5, using refractories that have the ability of resisting corrasion of alkali metals; 6 , cleaning the blast furnace periodically. The above recommendations are necessary for decreasing the circulation and accumulation of alkali metals effectively in blast furnace, reducing the harmful influence of alkali metals on blast furnace, increasing the smelting intensity, decreasing the coke rate, improving the gas permeability.
基于碱金属对高炉冶炼的上述危害,本文结合湘钢高炉的实际生产情况,通过理论分析、计算以及其他钢厂防治碱害的经验,提出防治高炉碱害的措施:1、减少入炉原、燃料的碱金属含量;2、提高烧结矿中的MgO含量、降低炉渣碱度、降低生铁含硅量、适当增加渣量;3、采用预还原的金属化球团或部分还原的烧结矿;4、提高焦炭的抗碱能力;5采用抗碱侵蚀的耐火材料;6、周期性性洗炉,以有效地减少碱金属在高炉内的循环富集,降低碱金属对高炉的危害,提高高炉的冶炼强度,降低焦比,改善高炉透气性。
