The glass fragments are used as the combination of the road surface, bricks for construction, insulating materials for glass wool and materials for honeycomb structure. Mix the damaged glass directly with the building materials and make the whole construction preparation. The broken container glass can also be used to make anti-light materials and clothing decoration products; Used to decorate the exterior of a building so that it has a beautiful optical effect; Can be directly ground into a variety of appearance, and then adhesive composition of technical art or small decoration products such as buttons.
The mix of glass and plastic waste can be molded into stone products.
Can be used to produce sewage pipes.
The heating type is used to crush the waste glass, melt it with the high temperature melting furnace, and then use the fast drawing method to get the glass fiber. This kind of glass fiber can be widely used in the production of asbestos tiles, glass jars and various building materials and daily supplies.
The production of glass bottles is one of the most energy-consuming packaging goods. It is very valuable for the recovery application. Figure 2 shows the recovery cycle of the glass bottle. How to make glass packaging recycle more effectively is a hot topic at home and abroad.
The reprocessing of reheating furnace refers to the reproduction of all kinds of refilled glass bottles for similar or similar packaging bottles, which is essentially a kind of recovery application of semi-finished materials for the production of glass bottles.
Detailed is the glass bottle that will be recovered, start to be sorted, cleaned, sorted by color and other pretreatment; The melting of the furnace is the same as the original production. All kinds of glass packaging bottles are made of recycled materials from the furnace through blowing and adsorbing.
Recovery furnace regeneration is a kind of recovery method suitable for all kinds of difficult or impossible reuse (such as broken glass bottles). This method USES more energy than the previous method.
The use of glass bottles for material recovery refers to the use of various glass bottle packaging wastes that cannot be reused for the production of various glass commodities to increase the quality of materials. The glass goods here are not only glass packaging products, but also other building materials and household glass products. Both methods consume more energy than the previous two methods.
A moderate amount of participation in broken glass is helpful for glass production, which is because broken glass can melt in low humidity compared with other materials. Therefore, less heat is required to recover the glass bottle, and the furnace wear can be reduced. The panel indicated that in glass production, the addition of 30 percent of the broken glass is appropriate, so progress can be made to recover the glass.
About 20 per cent of broken glass is currently used in the glass container industry to promote melting and mixing with materials such as sand, limestone and alkali. Seventy-five percent of the broken glass comes from the production of glass containers, and 25 percent comes from spent capacity.
(1) precise selection to remove impurities
It is necessary to remove impurities such as metals and ceramics from the bottle recall conjecture, as the glass container manufacturer requires the use of high purity materials. For example, the presence of metal covers in broken glass may constitute oxides that interfere with furnace operations; Ceramics and other foreign substances constitute disadvantages in the production of containers.
(2) color selection
Take back the use of color is also a question. Because coloured glass cannot be used when making colorless flint glass, and when producing amber glass, only 10% of green or flint glass is allowed, accordingly, the broken glass after spending is necessary to use artificial or machine for color selection. Broken glass if do not undertake colorific carry out direct use, can use to produce shallow green glass container only.
