Abstract: A light-weight, high-strength, and high-elasticity titanium alloy and an implementation method thereof. The titanium alloy is specifically Ti-8Al-2V-1Cr-0.75Zr, wherein the content of Al is 7.0% to 9.5%, the content of V is 0.5% to 4.0%, the content of Cr is 0.5% to 3.5%, the content of Zr is 0.5% to 2.0%, and the balance is Ti. The titanium alloy is obtained by vacuum arc remelting(VAR), after mold pressing through the adoption of sponge titanium, vanadium, chromium, aluminum zirconium pure, pure aluminum, aluminum vanadium alloy mixed consumable electrode. The titanium alloy is simple in preparation processing steps, low in processing cost, easy in production, and is applicable to various application fields with a requirement for a low-density and high-strength titanium alloy.

Abstract: A system for purifying mother liquid steam of polytetrafluoroethylene dispersion liquid comprises a concentration kettle (1), a defoaming pot (2), a gas-liquid separator (3) and a falling film absorption tower (4). A steam exit of the concentration kettle (1) is connected to an entrance of the defoaming pot (2). An exit of the defoaming pot (2) is connected to a feeding port of the gas-liquid separator (3). A gas exit of the gas-liquid separator (3) is connected to the falling film absorption tower (4). A liquid exit of the gas-liquid separator (3) is connected to the concentration kettle (1). A method for purifying mother liquid steam of polytetrafluoroethylene dispersion liquid by using the system is further provided.
