Problems solved by technology

However, due to the addition of cullet, the material will become brittle and even produce a large number of bubbles, thereby reducing the quality of the glass product, weakening its strength, and even making it impossible to produce directly due to the extremely poor forming performance. Therefore, the current cullet dosage is only It can account for 15-25% of the total raw material mass, otherwise it will cause changes in the glass structure, and such a dosage is far from meeting the requirements of energy saving and consumption reduction, so that a large amount of broken glass is still mainly stacked in the open air, which not only takes up valuable land resources, and cause serious environmental pollution, therefore, it is absolutely necessary to improve the existing technology, develop and develop a waste resource that does not affect product quality, and can maximize the use of cullet, a waste resource, to turn waste into treasure. , reduce the environmental pressure of the society, and create higher and better benefits for the enterprise and the society

Embodiment 1

[0043] A. Carry out the following pretreatments to the waste glass purchased: (1) use a conventional crusher to crush and screen the waste glass; (2) sort out the sundries in the waste glass after the screening, and clean it with water. spare;

[0044] B, based on 500Kg of raw materials, according to the following parts by mass:

[0045] Quartz sand 199.18kg

[0046] Soda ash 63.71kg

[0047] Feldspar 19.41kg

[0048] Limestone 19.78kg

[0049] Dolomite 43.91kg

[0050] Sodium sulfate 4.01kg

[0051] Waste glass 150kg

[0052] Mix the above-mentioned quartz sand, soda ash, feldspar, limestone, and dolomite into a material for subsequent use;

[0053] Mix the above-mentioned sodium sulfate and waste glass into b material for subsequent use;

[0054] C. Put the raw materials of step B into the glass melting furnace of the prior art, and introduce the glass into the U-shaped glass of the prior art through processes such as smelting, clarification, homogenization, and prim...

Abstract

The invention provides a building U-shaped glass produced by taking waste glass as raw material, which is characterized by comprising chemical components with the mass ratio: 71.50-72% of SiO2, 1.20-1.30% of Al2O3, 0.15-0.20% of Fe2O3, 8.50-11.20% of CaO, 2.50-3.50% of MgO and 14.00-16.50% of Na2O. The doping quantity of the waste glass can be greatly increased and even approaches to 100%, so thatthe waste glass which is the industrial waste can be fully utilized, and the problems of environmental stress caused by the waste glass, land resource occupation and the like are fundamentally solved; meanwhile, as the using quantity of the waste glass is increased, the cost of raw materials of the production enterprises can be reduced, and smelting energy consumption is lowered; furthermore, themelting point of the waste glass is far lower than that of quartz sand, so that considerable economic and social benefits are brought to the production enterprises and the society. Therefore, the building U-shaped glass can ensure the glass shaping property, is beneficial to improving the finished product ratio and reducing the rejection rate, improves the quality of products, and protects the environment.

Description

technical field [0001] The invention relates to a method for producing architectural profile glass, in particular to a method for producing U-shaped glass by using waste glass as a raw material, and belongs to the technical field of glass production. technical background [0002] In China, more than 12 million tons of waste cullet are not used in scientific and high-end recycled products every year. Most of the waste cullets are low-end and low-quality recycled products, which are usually discarded or buried deep in various types of garbage as solid waste, which not only causes serious environmental pollution, but also wastes precious glass resources. [0003] Existing glass, such as flat glass, daily-use glass, decorative glass, electronic glass, automotive glass, etc., can be described as diverse in variety and complicated in style. But no matter which kind of glass is inseparable from the most basic glass production process, that is to say, any kind of glass in the world...
