Influence of BN on properties of fired aluminum carbon magnesia carbon refractory 氮化硼对铝炭、镁炭耐火材料性能的影响
The reinforcements of nano silica / carbon black, nano titanium dioxide / carbon black, nano aluminum oxide / carbon black and silica / carbon black respectively to SBR were investigated and compared to that of carbon black alone. 研究了纳米白炭黑、纳米二氧化钛、纳米氧化铝和白炭黑分别与炭黑并用对SBR的补强性能,并与单独填充炭黑进行了对比。
The results show that the room-temperature fracture strength and elongation of aluminum coated low carbon steel plates are higher than those of low carbon steel plates. 结果表明,热轧低碳钢板热浸镀铝后的室温抗拉强度和延伸率均优于未镀铝的低碳钢板。
The result of a neutral salt spray test for 48 hours indicate that aluminum coated carbon steel tubes are more corrosion resistant than zinc coated low carbon steel tubes. 48h的中性盐雾试验结果显示热浸镀铝低碳钢管的耐蚀性远优于镀锌钢管。
The results showed that the three phosphonium salts all could well inhibit the corrosion of aluminum in MgCl 2 solution, and that the inhibitive efficiency of long carbon chain phosphonium salt was higher than that of short carbon chain phosphonium salt. 结果表明,季辚盐化合物具有较好的缓蚀作用,链长的季辚盐比链短的缓蚀效率高。
