Abstract
Description
Technical Field
[0001] This invention belongs to the field of glass manufacturing technology and relates to a glass formulation, particularly an improved high-quality, low-cost glass formulation. Background Technology
[0002] Molten glass generally refers to the molten raw material used in the glass manufacturing process, and its production is a core part of the glass industry. The production of molten glass begins with the preparation of raw materials, the main raw materials of which include cullet, quartz sand (providing silica), soda ash, limestone, etc. Auxiliary materials such as clarifying agents and coloring agents are also added to improve performance. The raw materials must be mixed in strict proportions to ensure uniform chemical composition, laying the foundation for subsequent melting.
[0003] The existing glass melt has a low alumina content, which affects the chemical stability of the glass to some extent. During the production of glass bottles, it is easy to cause the glass to detach. In addition, the raw material used is crushed glass, which is made by crushing large pieces of glass. The fragments generated by natural breakage cannot be utilized, which increases the cost of the glass to some extent. Summary of the Invention
[0004] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing an improved high-quality, low-cost glass formulation. The technical problem this invention aims to solve is: how to improve the chemical stability of glass and reduce production costs.
[0005] The objective of this invention can be achieved through the following technical solutions: An improved high-quality, low-cost glass formulation includes component A and component B. Component A consists of coarse and fine glass fragments, and component B consists of the following raw materials in parts by weight: 1300-1500 parts refined sand, 450-550 parts soda ash, 400-500 parts calcite, 300-400 parts potassium feldspar, 35-45 parts clarifying agent, 1-12 parts functional additives, and 1300-1500 parts colorant.
[0006] Preferably, component B is composed of the following raw materials in parts by weight: 1400 parts refined sand, 500 parts soda ash, 450 parts calcite, 350 parts potassium feldspar, 40 parts clarifying agent, 6 parts functional auxiliary material, and 1400 parts coloring auxiliary material.
[0007] Preferably, the coloring agent is tea coloring or high-quality white coloring.
[0008] Preferably, the functional additive is a mixture of two or more of the following: mixed carbon powder, mixed selenium powder, sodium sulfate, and mixed iron oxide red.
[0009] Preferably, the coarse glass fragments are glass shards with a diameter of 2 mm or more, and the fine glass fragments are glass shards with a diameter of less than 2 mm.
[0010] Preferably, the coarse glass fragments are supported by recycled waste glass shredders, and the fine glass fragments are obtained by screening and removing impurities from the debris generated after the natural breakage of waste glass.
[0011] Preferably, component A accounts for 48%-60% of the total amount.
[0012] Preferably, the potassium-sodium feldspar is composed of the following raw materials in the following proportions: potassium oxide 4.7-6.3%, sodium oxide 3.8-4.5%, aluminum oxide 15%-20%, silicon dioxide 70-74%, calcium oxide 0.2-0.3%, ferric oxide 0.25-0.4%, and magnesium oxide 0.15-0.25%.
[0013] Preferably, the moisture content of the refined sand is below 3%.
[0014] Compared with existing technologies, this improved high-quality, low-cost glass formulation has the following advantages: The glass formulation of this invention incorporates potassium and sodium feldspar to increase the alumina content in the glass mix, thereby enhancing chemical stability and effectively reducing glass bottle delamination. The selection of sand with low moisture content ensures more uniform mixing and improves chemical stability. Furthermore, the improved glass mix increases the specific gravity of glass powder smaller than 2mm, combining both smaller and larger glass powders to replace the original crushed glass. While this does not improve the quality of the glass bottle, it significantly reduces manufacturing costs. Attached Figure Description
