The control of the glass melting
一个。 Two classic chemical reaction way:
1. Salts of double decomposition reaction: by salts to silicate oxide glass formation reaction
most glass raw material has double decomposition reaction characteristics of salt:
sodium nitrate: 2 nano3 = 2 nano2 + O2; 4NaNO2=2Na2O+2N2+3O2
2. REDOX reaction: oxide from low to high states of reversible reaction
antimony trioxide: 2 + 3 o2 sb2o34sb
B. Glass is made of five stages namely silicate physical chemistry reaction and glass forming process:
1. Silicate formation: about 20 minutes or more, and cooperate with molten material surface;
2。 The formation of the glass: it's about five minutes, become contains a lot of bubble glass;
3。 Glass clarification: higher than the melting temperature 30 ℃ above, as hot as the center;
4。 Homogenization of glass: higher than melting temperature 30 ℃ above, centering on the hot;
5。 Glass cooling: cooling about 200 ~ 300 ℃, the distribution of feeding further adjustments.
