我公司是以生產、銷售、維護氣浮設備為一體的公司，近年來公司不斷發展技術力量，創新生產技術手段，生產的產品銷往全國各地，受到客戶的一致好評，讓大家了解一下氣浮設備的特性：

形成氣泡的大小和強度取決于空氣釋放時各種用途條件和水的表面張力大小。(表面張力是大小相等方向相反，分別作用在表面層相互接觸部分的一對力，它的作用方向總是與液面相切。

　　(1)氣泡半徑越小，泡內所受附加壓強越大，泡內空氣分子對氣泡膜的碰撞機率也越多、越劇烈。因此要獲得穩定的微細泡，氣泡膜強度要。

　　(2)氣泡小，浮速快，對水體的擾動小，不會撞碎絮粒。并且可增大氣泡和絮粒碰撞機率。但并非氣泡越細越好，氣泡過細影響上浮速度，因而氣浮池的大小和工程造價。此外投加一定量的表面活性劑，可有效降低水的表面張力系數，加強氣泡膜牢度，r也變小。

　　(3)向水中投加高溶解性無機鹽，可使氣泡膜牢度削弱，而使氣泡容易破裂或并大。（圖/文www.jack365.cn)

中譯英：

Our company is the production, sales, maintenance of air flotation equipment for the whole company, the development of the company technical force is constantly in recent years, technology innovation and production, products are sold throughout the country, by the customer the consistent high praise, today let everyone know about characteristics of floatation equipment:

The size of surface tension on bubble formation size and strength to air release various use conditions and water. (surface tension is equal in magnitude and opposite in direction, respectively. The effect of mutual contact of force, part of the surface layer of the direction of its action is always tangent with the surface of the liquid.

(1) the bubble radius is smaller, the bubble by additional pressure is greater, the collision probability of air molecules inside the bubble on the bubble film is more also, intense. Therefore, to obtain stable micro bubble, bubble film strength to ensure.

(2) the bubble is small, floating rate, small disturbance to the water, not broken flocs. And can increase the bubble and floc collision probability. But not the bubble the more detailed the better, but the floating rate and bubble effect, flotation pool size and cost of the project. In addition, cast surface active additive quantity of agent, surface tension coefficient can effectively reduce water, strengthen the bubble film fastness, r also becomes small.

(3) addition of soluble inorganic salt to the water, can make the air bubble film fastness to weaken, and the bubble rupture easily or and.
