The manufacturing theory of foam glass was just suggested in nineteen thirty for latter half.As an example, it is by with specific group Into glass and the foaming shape of the reducing agent such as carbon and oxidizing component containing oxide, sulfate (sulfate) or other forms Crushed after being mixed together into agent, then the mixture of crushing is put into defined container or mould and is fired, until It is softened or melted.
In the heat treatment process, cause between carbon and oxysulfide (or oxidant or glass oxide) oxidation-also Original reaction, as a result, the glass of melting is contained SO2、CO2、N2、H2S or other gases, this will prepare low-density and use In the material for forming the structure for hindering heat transfer and radiation, so as to form stomata in glass.As a result optimal in result In the case of, glass can have the airtight air vent structure for not penetrating into water or vapor or other liquid and gas etc..
For come the manufacturing process of foam-glass block manufactured, disclosing substantial amounts of result of study by this manufacturing theory And related patents.Healthy and free from worry (Pittsburg Corning) company of Pittsburgh in the U.S. proposes, in order to manufacture commercialized foam glass Glass needs disposably to produce the foam glass production of raw material for use glass with special composition.In order to which foam glass is made Glass, in common glass manufacture with adding CaCO in material composition3、MgCO3、Na2O、As2O3Deng Multiple components, and by 1300 ~1600 DEG C of melting process manufactures foam glass production of raw material for use glass, so as to the manufacture for foam glass.Then Glass made of will be such is crushed, and adding blowing promotor, the blowing promotors such as carbon component wherein can be with other component The gas for playing the role of foaming agent is directly generated after reaction, is then uniformly mixed them, the foam glass mixed is manufactured As defined in the loading of base glass powder in container, and preheated at 400~650 DEG C, under conditions of 800~900 DEG C Foaming process is carried out, then carries out being used for the heat treatment processes such as stabilized cooling, slow cooling, it is laggard then to cut into prescribed level Row packing and selling.
But in this process, during foam glass production of raw material for use glass is manufactured, heat treatment during melting Temperature is 1300~1600 DEG C, this needs substantial amounts of energy, equipment investment and administration fee is thus needed, so that foam glass The producing cost of glass production of raw material for use glass accounts for more than half of foam glass production cost.
In addition, when manufacturing foam glass, Accurate Prediction goes out the foaming section of glass and manufactures at low temperature as much as possible It is very important.Although however, there are many manufacturing theories in this way to manufacture the result of study of foam-glass block process And related patents, but the research for foam glass generation section is fewer and fewer.
All the time, the realtime graphic implemented in macroscopical stage by using heating microscope, to implement in order to just The really experiment in prediction foam glass generation section.But so it is difficult to predict going out glass accurately to foam section, because that can only be measured to Millimeter (mm) unit and be restricted.
