the raw material into glass

[qizhenapp]

<p>The calendering method is to melt the raw material into glass, and then press the glass, and then cut into a sheet by heat treatment. Sintering method is the first raw material melting into glass, quenched into a broken material, and then crushed into the mold paving, put into the furnace heat treatment to obtain glass-ceramic plate. Both of which have advantages and disadvantages, the former can be continuous water production, low heat consumption, but the variety of single; the latter can do variety, but the process is complex, high demand for mold, finished bubble is its main weakness. </p><p>(three) The development of modern construction industry, the demand for high-grade decorative materials is growing, demanding more and more. The traditional decorative materials such as marble, granite and other anti-erosion ability, resistance to weathering ability, easy to wear and other shortcomings, not suitable for interior and exterior decoration materials.</p><p> Many of the granite, pyroxene, black shale and other materials, decoration, interior and exterior finishes, found that they and uranium, thorium and other elements symbiotic, radioactive intensity exceeded, has become an invisible killer, the objective need to develop replacement products. Microcrystalline glass is a good way to overcome these shortcomings, the development trend shows that the glass-ceramic decorative panels for internal and external decoration materials promising.</p>
