What are the criteria for identifying qualified glass wine bottles? The Easypack glassware wine bottle manufacturer will tell you about the main factors that affect the quality of glass wine bottles: first to identify the internal quality of a glass wine bottle, of course, cold burst test and internal stress test are required. Wait for a series of tests. When we get a glass wine bottle that is smooth and bright, with no color difference, no rotten thread or frying opening, and the bottom of the bottle is uniform in thickness and there are no obvious defects, it can be counted as a qualified glass wine bottle. Looking at the glass wine bottle in the bright light, there are dense small bubbles on the bottle body. The direct consequence of this situation is that the internal stress of the glass wine bottle is not enough, which is mainly caused by the insufficient temperature of the melting pool and insufficient melting of the glass material liquid. Yes, it is a serious quality issue. Secondly: If the surface of the mold is oxidized after a long period of unused or continuous use causes some impurities to adhere to the mold surface, the resulting glass wine bottle will be slightly uneven. Although it does not affect the quality in essence, it severely affects the appearance.
Glass bottles and cans are widely used, and glass bottles and cans should have certain performance and meet certain quality standards. The following is a brief introduction to application manufacturers, hoping to help the majority of purchasing manufacturers:
①Glass quality: pure and uniform, without defects such as sand, streaks, and bubbles. Colorless glass has high transparency; the color of colored glass is uniform and stable, and can absorb light energy of a certain wavelength.
②Physical and chemical properties: It has certain chemical stability and does not interact with the contents. It has a certain degree of shock resistance and mechanical strength. It can withstand heating and cooling processes such as washing and sterilization, as well as withstanding filling, storage and transportation. It can remain undamaged when encountering general internal and external stress, vibration, and impact.
③Forming quality: maintain a certain capacity, weight and shape, uniform wall thickness, smooth and flat mouth to ensure convenient filling and good sealing. There are no defects such as distortion, uneven surface, unevenness and cracks.
Glass bottle manufacturers can manufacture mainly including batch preparation, melting, forming, annealing, surface treatment and processing, inspection and packaging.
①Batch preparation: including storage, weighing, mixing and conveying of batch materials. The batch materials are required to be uniformly mixed and have stable chemical composition.
②Melting: The melting of bottle glass is mostly carried out in a continuous operation flame tank furnace (see glass melting furnace). The daily output of horizontal flame tank kilns generally exceeds 200t, and the large-scale ones reach 400～500t. The daily output of the horseshoe-shaped flame tank kiln is mostly below 200t. The glass melting temperature is up to 1580～1600℃. The energy consumption of melting accounts for about 70% of the total energy consumption in production. It can effectively save energy by comprehensively insulating the tank, increasing the capacity of checker bricks in the regenerator, improving the distribution of the piles, increasing the combustion efficiency and controlling the convection of the glass liquid. Bubbling in the melting tank can improve the convection of the glass liquid, strengthen the clarification and homogenization process, and increase the output. The use of electric heating in the flame kiln can increase the output and improve the quality without increasing the furnace.
