Description
技术领域technical field
本发明属于固体表面润湿技术领域，具体涉及的是一种固液撞击-飞溅性能测试方法。The invention belongs to the technical field of solid surface wetting, and in particular relates to a test method for solid-liquid impact-splash performance.
背景技术Background technique
飞机飞行中机翼会与空中的水滴发生碰撞，碰撞后水滴可能铺展在机翼表面、也可能飞离机翼表面。铺展在机翼表面的水会增加飞机的质量，当温度合适时会出现结冰现象，进而影响飞行安全。飞溅的液滴则可能撞击到飞机的薄弱部位。During the flight of the aircraft, the wings will collide with water droplets in the air. After the collision, the water droplets may spread on the surface of the wing or fly away from the surface of the wing. The water spread on the surface of the wing will increase the mass of the aircraft, and when the temperature is right, it will freeze, which will affect flight safety. Splashing droplets may hit weak parts of the aircraft.
单辊快淬法，亦称溶体冷辊旋凝法、连铸薄带法(见图3)。金属溶液喷射在高速旋转的冷却辊表面并在重力、润湿作用下铺展形成熔池；熔池与冷却辊接触的界面层因急剧冷却而凝固，并随冷却辊一起旋转、继续冷却，形成非晶金属薄带；非晶金属薄带自身收缩，在离心力作用下脱离辊轮。熔池中的液体在高速运动过程中有时会脱离冷却辊，飞溅的液滴冷却结晶，使生产效率降低、生产成本增加。部分高粘度、不润湿的合金液体表现出严重的飞溅现象，难以形成非晶金属薄带。The single-roll quick quenching method is also called the solution cooling roll spinning method and the continuous casting strip method (see Figure 3). The metal solution is sprayed on the surface of the cooling roll rotating at high speed and spreads under the action of gravity and wetting to form a molten pool; the interface layer between the molten pool and the cooling roll is solidified due to rapid cooling, and rotates with the cooling roll to continue cooling, forming a Crystalline metal thin strip; amorphous metal thin strip shrinks by itself and breaks away from the roller under the action of centrifugal force. The liquid in the molten pool sometimes breaks away from the cooling roller during high-speed movement, and the splashed liquid droplets cool and crystallize, which reduces production efficiency and increases production costs. Some high-viscosity, non-wetting alloy liquids exhibit severe splashing, making it difficult to form amorphous metal ribbons.
上述两个过程中，液体撞击在高速运动的固体表面，在润湿性能的影响下液体铺展，固体表面与液体之间的热传导使得部分液体降温并凝固成为固体，未凝固的液体飞离固体表面形成飞溅的液滴。影响液滴撞击高速运动固体表面过程的因素包括：1撞击角度，2撞击的相对速度，3液滴与固体表面的温差，4液滴在固体表面的润湿性等。实际过程中是多种因素共同作用的结果，这就需要能够测试各种条件对飞溅性能影响的测试方法。In the above two processes, the liquid hits the high-speed moving solid surface, and the liquid spreads under the influence of wettability. The heat conduction between the solid surface and the liquid makes part of the liquid cool down and solidify, and the unsolidified liquid flies away from the solid surface. Splash droplets are formed. The factors affecting the process of droplet impacting the high-speed moving solid surface include: 1. The impact angle, 2. The relative velocity of the impact, 3. The temperature difference between the droplet and the solid surface, 4. The wettability of the droplet on the solid surface, etc. The actual process is the result of the joint action of various factors, which requires a test method that can test the influence of various conditions on the splash performance.
现在一般采用高速摄像机拍摄撞击过程，进而表征撞击-飞溅性能。在高速运动时撞击-飞溅过程时间短、粘附力对过程的影响较小，造成标准困难。这就需要简单、高效的测试方法标征固体表面润湿性能对固液撞击-飞溅离过程的影响。Nowadays, a high-speed camera is generally used to shoot the impact process, and then characterize the impact-splash performance. The impact-splash process time is short at high speed, and the adhesion force has little influence on the process, which makes the standard difficult. This requires a simple and efficient test method to characterize the influence of solid surface wetting properties on the solid-liquid impact-splash process.

采用的技术方案是：采用倾斜角度可调式旋转盘，高速运动的液滴撞击在转动的旋转盘表面上，撞击瞬间液体所受离心力在水平方向，粘附在旋转盘表面的液滴所受离心力的方向随时间推移而变化，飞溅液滴脱离旋转盘的时刻所受离心力的方向直接影响了其运动轨迹和坠落点，坠落点的位置可以表征液滴撞击-飞溅过程中转速、重力、润湿性等因素对飞溅液滴的综合影响。The technical solution adopted is: using a rotating disk with adjustable inclination angle, the liquid droplets moving at high speed hit the surface of the rotating rotating disk, the centrifugal force on the liquid at the moment of impact is in the horizontal direction, and the centrifugal force on the liquid droplets adhering to the surface of the rotating disk The direction of the splashing droplet changes with time. The direction of the centrifugal force at the moment when the splashed droplet leaves the rotating disk directly affects its trajectory and the falling point. The position of the falling point can represent the rotational speed, gravity, wetting and The comprehensive influence of factors such as sex and other factors on splashing droplets.

The liquid impact-splash performance test method on the surface of an inclined rotating disk, characterized in that the angle between the rotating axis of the rotating disk and the direction of gravity can be adjusted between 0° and 90°, and the droplet impacts on the surface rotating around the central axis On the surface of the rotating disk, the centrifugal force on the droplet at the moment of impact is parallel to the horizontal plane, and the droplet flies away from the rotating disk under the action of adhesion, centrifugal force and gravity; the three-dimensional space of the splash drop point is recorded with the impact point on the rotating disk as the origin Coordinates; calculate the distance s between the landing point of the splashing droplet and the droplet landing line, test the influence of the inclination angle of the rotating disk on the distance s, and characterize the influence of the wetting property of the solid surface on the solid-liquid impact-splash process.
2、进一步，旋转盘的旋转速度可控，旋转速度小于十万转每秒。2. Further, the rotation speed of the rotating disk is controllable, and the rotation speed is less than 100,000 revolutions per second.
3、进一步，使用电加热装置控制旋转盘温度。3. Further, use an electric heating device to control the temperature of the rotating disk.
4、进一步，使用旋转盘内部管道通冷却剂的方法控制旋转盘温度。4. Further, the temperature of the rotating disk is controlled by using the method of passing coolant through the pipe inside the rotating disk.

Further, by setting the rotation speed, temperature, roughness, material and droplet temperature and impact velocity of the rotating disk; it can simulate the rotation speed, temperature, roughness, material and molten metal of the cooling roll in the production process of amorphous alloy thin strip The temperature and liquid injection speed; by setting the inclination angle of the rotating disk, and then simulating the impact angle of the droplets, the comprehensive influence of various factors on the solid-liquid impact-splash process is tested.
本发明利用离心力方向的改变使飞溅液滴的坠落点可以表征撞击过程中各种因素的综合作用。通过测试旋转盘倾斜角度与飞溅液滴坠落点的关系，从而优化金属熔液在冷却辊表面落点的位置，减少液滴飞溅，提高非晶合金薄带的质量稳定性。从液滴接触固体表面到液滴飞溅的过程中，1液滴在润湿作用下与固体表面形成润湿角，2在热传导作用下液滴温度发生改变引起体积变化，3粘附力拖动液滴随旋转盘转动，4飞溅液滴与旋转盘接触过程中受粘附力作用。从液滴撞击到液滴飞离的时间越长，液滴随旋转盘运动的角度就越大，液滴飞溅方向的改变就越大。当旋转盘温度低于液体凝固点时，会有部分液体冷却凝固成为固体，飞溅液滴的质量将减小。当旋转盘温度高于液体沸点时，会有部分液体沸腾成为汽体，飞溅液滴的质量将减小。旋转盘转速可控，当转速为零时相当于撞击在静止表面上的飞溅测试状态。液滴发生装置可以控制液滴撞击在旋转盘表面的速度，控制方法有自由落体低落、加压喷射等。The invention utilizes the change of the direction of the centrifugal force so that the falling point of the splashed liquid droplet can represent the comprehensive effect of various factors in the impact process. By testing the relationship between the inclination angle of the rotating disk and the falling point of splashed droplets, the position of the molten metal on the surface of the cooling roll can be optimized, the droplet splash can be reduced, and the quality stability of the amorphous alloy thin strip can be improved. During the process from when the droplet touches the solid surface to when the droplet splashes, 1. The droplet forms a wetting angle with the solid surface under the action of wetting. 2. The temperature of the droplet changes under the action of heat conduction to cause a volume change. 3. Adhesive force drags The droplet rotates with the rotating disk, and the splashing droplet is affected by the adhesion force during the contact process with the rotating disk. The longer the time from droplet impact to droplet flying, the larger the angle of droplet motion with the rotating disk, and the greater the change of droplet splash direction. When the temperature of the rotating disk is lower than the freezing point of the liquid, part of the liquid will cool and solidify to become a solid, and the mass of the splashed droplets will decrease. When the temperature of the rotating disk is higher than the boiling point of the liquid, part of the liquid will boil and become a vapor, and the mass of the splashed droplets will decrease. The rotation speed of the rotating disk is controllable, and when the rotation speed is zero, it is equivalent to the splash test state of impacting on a stationary surface. The droplet generating device can control the speed at which the droplets hit the surface of the rotating disk, and the control methods include free fall, pressurized spraying, etc.
