What is the liquid medium tempering method?

Fanyu 2018-06-01 11:04:23
Liquid medium tempered liquid medium tempering method, namely liquid cooling method. The so-called liquid cooling method is to heat the glass to a temperature near the softening point, and release the molten steel in a quench tank filled with liquid. In this case, brine may be used as the cooling medium, and mineral oil may be used as the cooling medium. Of course, additives such as toluene or carbon tetrachloride may also be added to the mineral oil. Some special quench oils and silicone oils can also be used. In the liquid tempering, since the edge of the glass sheet first enters the quench tank, bursts due to uneven stress occur. In order to solve this problem, it can be pre-cooled by air-cooling or spraying, and then quenched in organic liquid. It is also possible to put water and organic solution in the quench tank. The organic solution floats on top of the water when it is heated.glassWhen placed in a tank, the organic solution acts as a precooling, absorbing a portion of the heat, and then rapidly cooling in the water. In addition to immersing the cooling liquid, the liquid spray method may also be used, but the immersion method is generally used. Britain's Triplex company, early in the 1980s, used a liquid medium method to temper glass with a thickness of 0.75 to 1.5 mm, ending the history that physical tempering could not temper thin glass. The difficulty of the liquid tempering method is to establish a reasonable liquid cooling process system. Two problems that should be paid attention to in the liquid cooling tempering are as follows: Firstly, an excessively high compressive stress layer is generated, and secondly, the glass burst is avoided. Advantages and Disadvantages: Using the liquid medium tempering method, because the specific heat of water is larger and the heat of gasification is higher, the dosage is greatly reduced, so that the energy consumption is reduced, the cost is reduced, and the cooling speed is fast, the safety performance is high, and the deformation is small. Since the glass is heated and then inserted into the liquid medium during cooling, the large-area glass sheet is susceptible to heat unevenness and affects the quality and yield. Range of application: It is mainly suitable for tempering thin glasses of various sizes, such as glasses. LCD glass, optical instrumentation glass.
