Limestone is used to make glass?
With the above raw materials, grinding, and according to a certain proportion of mixed uniform (add a part of water, improve uniformity and other process requirements), and then into the glass furnace melting
The glass melting process includes: formation of silicate, formation of vitreous body, clarification, homogenization and coolingLimestone, dolomite, soda, Glauber's salt will produce gas, so that it is not only the glass formation and harmless, but also conducive to the refining of glass and homogenization, factory general also added a part of clarifier, generating a lot of bubbles, bubbles in the floatation process, combined with small bubbles, this is the glass fining mechanism.
Window glass: also known as sodium calcium silicate glass, the main composition of Na2O-CaO-SiO2 and MgOGlass raw materials: Limestone (CaCO3), dolomite (MgCO3-CaCO3), soda ash (Na2CO3), Glauber's salt (Na2SO4), quartz sand (SiO2) and so on
