1. Waste cullet recycling to produce new products The transformation of glass bottle packaging refers to the direct processing of the recovered glass packaging and conversion to other useful materials. The non-heating application is also called mechanical application. The detailed method is to directly destroy or firstly recover the recovered cold acid glass according to the application, and then mechanically break them into small particles, or grind them into small glass balls for use. Its application path is as follows: Use glass cullet as a combination of pavement, brick for construction, glass wool insulation material and honeycomb structure data; The damaged glass is directly mixed and mixed with the construction materials to make a prefabricated whole construction; Destroyed container glass can also be used to make reflector materials and clothing accessories; Used to decorate the exterior of the building to give it a beautiful optical effect; It can be directly ground into various shapes, and then bonded to form technical art or small decoration such as buttons. A mixture of glass and plastic waste can be molded into a slate product. Can be used to produce sewage pipes. The heating type is to smash the waste glass, melt it with a high-temperature melting furnace, and then obtain the glass fiber by rapid drawing. This kind of glass fiber can be widely used in the production of asbestos tile, glass cylinder and various building materials and daily necessities. The production of glass bottles is one of the most energy-intensive packaging products. It is very valuable for retracting the application. Figure 2 shows the recovery cycle of the glass bottle. How to use glass packaging more effectively is a hot topic at home and abroad. Re-refining refers to the re-production of various recycled glass bottles for the same or similar bottles. This is essentially a reclaiming operation for supplying semi-finished materials for glass bottles.

2. The details are the pre-treatment, cleaning, color classification and other pre-treatment of the recovered glass bottles; the melting of the furnace is the same as the original production, and it is no longer smashed; the materials recycled by the furnace are blown, adsorbed, etc. Make a variety of glass bottles. Recycling furnace regeneration is a suitable method for retracting glass bottles that are difficult to reuse or cannot be reused (such as broken glass bottles. This method consumes more energy than the previous method. Recycling of recycled glass bottles refers to the use of various glass bottle packaging wastes that cannot be reused for the production of various glass products. The glass products here are not only glass packaging products, but also other commercial waste materials such as building materials and daily glass products. This method consumes more energy than the first two methods of recovery. Appropriate amount of cullet is helpful in the production of glass, because cullet can be melted at lower humidity than other materials. Therefore, less heat is required to recover the glass bottle, and the wear of the furnace can be reduced. The study indicated that in the glass making process, it is suitable to incorporate 30% of the broken glass, so it is also possible to improve the recovery of the glass. At present, the glass container industry uses about 20% of broken glass in the production process to promote melting and mixing with materials such as sand, limestone and alkali. 75% of the broken glass comes from the production process of the glass container, and 25% comes from the capacity after the expense. (1) Precision selection to remove impurities In the recovery of glass bottles, it is necessary to remove impurities such as metal and ceramics.

3. This is because glass container manufacturers need to use high-purity materials. For example, a metal cover or the like in the cullet may constitute an oxide that disturbs the operation of the furnace; ceramics and other foreign materials constitute a disadvantage in the production of the container. (2) Color selection Retracting the use of color is also a question. Since colored glass can not be used in the production of colorless flint glass, only a 10% green or flint glass is allowed to produce amber glass. Therefore, it is necessary to manually or machine the color selection after the spent glass is used. If the broken glass is used directly without color picking, it can only be used to produce light green glass containers.
