Glass manufacturing industry

Application of microporous insulation board in glass industry

Glass making is a very energy consuming process, with about 75% to 85% of the energy consumed during the melting of the glass.
At any stage of glass production, reducing energy losses can be good in two ways:
First, because the energy is the most expensive consumables manufacturing process, save energy can save costs;
Second, in the manufacturing process, the higher the utilization of thermal efficiency, the more accurate control of glass melt viscosity. This makes it easier to control the quality of the product, leading to a further reduction in the cost of the product.
Therefore, the high efficiency of refractories and thermal insulation materials used in glass manufacturing equipment is becoming more and more important. In addition to the glass in the glass melt, the post processing stage, such as auto glass hot bending, excellent thermal insulation materials is also extremely important for energy saving and high quality products.

Application of glass melting kiln

Each part of the glass melting kiln, comprising a kiln roof, parapet, wall and the bottom of the pool, small furnace and regenerator implementation of reasonable insulation, is an important way to improve the thermal efficiency. The kiln body heat preservation, not only can significantly reduce the heat loss of masonry surface to the outside world, improve working conditions, and because of the heat capacity of the kiln body increases, the temperature in the kiln system is conducive to the stability and improvement of the actual temperature of the molten glass itself, the flow and temperature distribution of glass liquid pool is more reasonable. Therefore, the kiln body heat preservation has become the main measures to increase the discharge capacity, improve the quality of the glass and reduce the fuel consumption.

On the application of hot bending processing of automobile glass

1 many of the automotive glass using gravity thermal bending method for production. It is the ordinary flat glass level pre processed on the mold ring, and sent to the furnace heated to the softening point (650 C) nearby, with a vacuum suction cup, let go of glass as a free fall, and forming sag due to gravity sticking to the die ring, then quickly sent to the cooling air the gate of quench tempering, finally transported to the unloading table. Production parameters, especially heat, need to be strictly controlled.

2 most common silicate fiber insulation materials and mineral wool is more than 400 DEG C when the product will have some cumulative damage. This results in the collapse of the insulating material and the corresponding weakening of the adiabatic performance.

3 microporous insulation board in the running cycle is long in prolonged exposure under high temperature, not only the thermal conductivity than traditional thermal insulation materials and insulation materials of low times, insulation performance is very stable.

For feeding machine

For feeding machine nanoporous super thermal insulation material for prefabricated insulation feeder basin can be directly affects the quality and cost of glass products. The basin can obtain more uniform temperature, the glass flow through an orifice is more uniform. The resulting glass clot has uniform size and minimum weight.

Insulation ring nanoporous super insulation materials as the feeder and around the orifice of the pot cover can accurately control the temperature and the size of the glass. The user can customize the size to facilitate rapid installation and accurate matching, and minimize downtime.

Reflux heat exchanger

Hot gas reflux heat exchanger, through the pipeline system to supply 750 degrees C of hot air to the combustion furnace, reduce heat loss is very important. The temperature drop of the reflux heat exchanger and the final burner is less than 30 C. Because all the laying of the pipeline is supported by the structure of the heat exchanger, the weight of the insulation becomes very critical. Compared with the traditional thermal insulation, the super thermal insulation material is thinner and lighter. And in the long-term exposure to high temperature with adiabatic stability. Visible changes are only minor damage to the exposed surface of the glass cloth. The material itself does not change.
