[0015] in:

[0016] 1. The operating range (WR) is equivalent to the temperature range of the glass liquid surface during forming;

[0017] 2. The operating range index (WRI) is an indicative number of the operating (forming) range, which can represent the length of the material;

[0018] 3. Crystallization index: Positive number means no crystallization, negative number means crystallization potential.

[0019] 4. The relative machine speed (RMS) reflects the forming characteristics of different glasses. It is expressed as a percentage. It is relative and can be compared, but cannot be used for the calculation of absolute numbers.

[0020] Introduce Na 2 The raw material of O is soda ash. Soda ash is a chemical raw material, the price is relatively expensive, and it has a great impact ...

Abstract

The invention relates to a bottle glass formula, wherein the bottle glass comprises, by weight, 69.5-72.5% of SiO2, 1.9-3.1% of AlO3, 10.2-10.6% of CaO, 2.0-2.5% of MgO, 12.8-13.0% of Na2O, 0.3-0.7% of K2O, less than or equal to 0.3% of Fe2O3, and less than or equal to 0.3+/-0.1%. According to the bottle glass formula of the present invention, in the high calcium formula, the total content of CaO+MgO is increased, the Na2O amount is reduced, and the appropriate MgO content is maintained, such that the material performance of the glass is adjusted, the molding performance of the glass is improved, and the relative machine speed is increased and the water resistance (HGB) of the glass product is substantially increased in the case of the same mold cooling air flow. In addition, the soda ash consumption is reduced so as to easily achieve energy saving and reduce cost.

Description

technical field [0001] The invention relates to a bottle glass formulation, in particular to a low-magnesium, low-alkali, and high-calcium bottle glass formulation. Background technique [0002] Glass composition can have a significant impact on both glass performance and cost. With the improvement of the molding speed of the bottle making machine, the glass composition of bottles and jars generally adopts high-calcium glass formula. In the chemical composition of high-calcium glass formula: the total content of CaO+MgO is 10-11%, of which the content of MgO is 0.2-2.0%, Na 2 The O content is above 14%. But there is following defect in existing high-calcium glass formula, Ca ++ The ions are more active at high temperature, which can reduce the viscosity of the glass and promote the melting and clarification of the glass. But if there is more CaO content in the glass, when the glass temperature decreases, the viscosity of the glass will increase rapidly, which will shorte...
