The main raw material for the impact of float glass cost?
Fuel prices: heavy oil, natural gas or coal, etc., because of the large number of long-term consumption, so it is also an important factor affecting product costs.
About the 70% main components of float glass is silica, the main raw material is corresponding to the sandstone or silica sand (sand), the raw material price level will seriously affect the glass manufacturing cost.
Process: mainly to see whether the enterprise has mastered the key technology of float process control. For example, master the melting technology, need to have stripe analysis equipment to monitor, can detect fault signs in advance, timely fine-tuning, can avoid major accidents, development. In the case of melting stability, general forming and annealing are relatively easy to achieve stability; the products produced by such a line are stable and the cost will be greatly reduced. But at present, the only part of enterprises to master the technology, many enterprises are repeatedly in fluctuation, a fluctuation of about 3-7 days, so the product quality can not guarantee long-term stability, there is no guarantee to do the processing of glass, benefits decline.
