| Popis: | 95 Scratchitti on the glasses of pubic utilities has become a common but serious problem in the United States, Europe, and Australia. In order to solve the serious glass scratchitti problem that a new technique developed in removal of scratches on glasses utilizes flame to heat the surface of the glass and a thin layer, of the same depth of the glass scratches, will melt and appears obvious viscosity. Then, during quenching to the ambient temperature, the scratches will be “fixed” by the surface tension until they are removed and the surface of the glass turns out to be smooth, which is the technique we call “Controlled Fire Polishing”. The thesis integrated the observation and research of glass characteristics change with temperature. In order to make machine operate as reliably as possible, it was proposed that a mechanism design and improvement based on the physical property of glass change with temperature. By proceeding the fire polishing experiment, the design and improvement could be verified, and it can be discussed that the influence on fire polished glass in different condition. After fire polishing experiment, we could compare the result of experiment and measurement to conclude the suggestion of the new fire polishing machine of next generation. |
