Theoretical analysis on three series of cements, i. e. Portland cement, high alumina cement and sulpho-aluminous cement, shows that alkalinity of the pore fluid of the balanced hydration product of sulpho-aluminous cement is the lowest, and its strength and alkalinity can be adjusted further by the adjustment of its components.

目前硅酸盐水泥、铝酸盐水泥、硫铝酸盐水泥等三大系列水泥的理论分析表明：硫铝酸盐水泥系列水化产物平衡时的液相碱度是最低的，且经过改性还可以进一步改善其强度和碱度等综合性能。

The premary tests show that three of them can obviously improve the mechanical properties of soft PVC/L-CaCO3 materials;however, they almost heve no effect on PP/L-CaCO3 blends. This suggests that the coupling effect of the aluminates be not only re...

初步试验表明，有3种铝酸酯可明显提高软质PVC／L－CaCO_3共混物的力学性能，但4种铝酸酯对PP／L－CaCO_3共混物的力学性能均无改善，说明铝酸酯的偶联作用不但与它们的分子结构有关，而且和偶联的对象有关。

With the help of recommended abrasives and techniques, through the process of heating – roughly hot rolling – precisely hot rolling in a variety a machines, hot rolls can be shaped into high-precision aluminium belts, which shall better meet the growing needs of the PS baseboards for pots and the simifinished aluminium foil sheets, for there is a big market gap and high grade request for high-precision aluminium belts in the market.

Consideration of microstructure, the metal material has a face-centered cubic lattice of the austenitic steel, Reducing Valves copper and aluminum do not appear in the low temperature low temperature brittleness, but the hardness of aluminum and aluminum alloys is not high, the sealing surface of the wear-resistant aluminum , anti-scratch performance is poor, so the use of low-temperature valves have certain limitations, only used in low voltage and small-caliber valve.

从金相考虑，金属材料中具有面心立方晶格的奥氏体钢、铜和铝在低温状态下不会出现低温脆性，但因铝及铝合金的硬度不高，铝密封面的耐磨、耐擦伤性能差，所以在低温阀门中的使用有一定的限制，仅用于低压和小口径阀门中。
