Main process configuration and development prospec

  • Detail

Since entering the 21st century, with the further deepening of the national reform and opening-up policy, China's economic development has changed with each passing day. According to researchers' computer calculations, remarkable changes have taken place and remarkable achievements have been made. The daily-use glass industry has mushroomed and developed rapidly during this period. Some powerful enterprises have shown a good development trend in terms of equipment level and production capacity. In 2008, the output of daily-use glass above Designated Size in China has reached 1445. 70000 tons. However, there are still a large number of enterprises in the industry whose overall level is not high and their overall development is weak

great changes have taken place in the international daily-use glass winding film industry in recent years. The demand for our bottles in the domestic and foreign bottle glass market is increasing, but the requirements for product quality are also higher and higher, which brings new development opportunities to the daily-use glass industry. Therefore, how to deal with the new development situation, clarify our future development direction, and further improve the overall level of the industry is an important problem we are facing at present

next, we will discuss with you the development of the main processes and configurations of bottle glass production in China in the future, in order to promote the sound and rapid development of industrial technology progress. Developed countries with a high level of daily-use glass industry have embarked on a relatively mature development path. According to the actual situation of our country, we can selectively learn from their experience and innovate our development in the view of "making foreign things serve China", so as to build a powerful country of daily-use glass as soon as possible

batching process: the selection and preparation of glass raw materials are rigorous, standardized and scientific, which is the source of the quality of glass products. The granularity and purity of raw materials, the specification, cleaning degree, impurity content and color of broken glass will affect the quality of glass. The selection of raw materials and the accuracy and stability of the batching process are important links related to product quality, environmental protection and civilized production. Many enterprises often neglect the batching process in the process of investment, especially in the case of low labor costs, which is not paid attention to and easy to be simplified, resulting in inaccurate addition and weighing of raw material components, uneven mixing, resulting in the quality of glass liquid can not be guaranteed, dust flying, serious environmental pollution, and potential serious occupational disease hazards. Automatic batching system has been widely used in the world for a long time, and China also has mature experience in this regard. In the large-scale production of glass industry with conditions, computer-controlled batching system should gradually replace manual batching

glass kiln: glass kiln is the heart of glass industry production and the main equipment of energy consumption. At present, the kilns in operation in China are mainly flame kilns, with a high level of energy consumption (generally around 300-500 kg standard coal/ton of finished products, and the international advanced level is equivalent to 150-200 kg standard coal/ton of finished products); The melting rate is low (generally 1.5 ~ 2 tons of liquid glass/square meter melting area · day, the international advanced level is 3 ~ 3.6 tons of I-steel liquid glass/square meter melting area · day), and the periodic melting rate is low (the international can exceed 10000 tons of liquid glass/furnace operation cycle, and the domestic is 2400 ~ 6200 tons of liquid glass/furnace operation cycle). This is also related to our enterprise's product structure, the size of furnace melting area, and the reasonable configuration of production line; In terms of energy structure, we mainly choose coal and oil at present, with low heat utilization rate and serious pollution. At present, clean energy such as natural gas and electricity are widely used internationally, with high heat utilization rate and less pollution. That is, most enterprises that use oil as fuel adopt electric melting aid and pure oxygen combustion technology to improve thermal efficiency and melting rate and reduce pollution. In terms of kiln life, our kilns are generally 4-6 years, while the international advanced level is about 10 years, and a few kilns have a life of more than 12 years. Of course, the investment cost of using refractory materials and materials for one-time guarantee test can be fixed on the equipment is higher, but the general ledger may be lower than the investment of kiln shutdown and overhaul once every 4-5 years. We need to absorb international advanced experience in combination with national conditions. In terms of automatic control of kilns, almost all foreign countries have adopted automatic control technology for the melting process of molten glass, while most of our kilns have not been installed with automatic control systems. In order to improve the melting quality, prolong the service life of kilns and do a good job in energy conservation and emission reduction, automatic control systems of kilns are indispensable

molding process: molding process has a great impact on product quality. In terms of manual process (such as glassware and special shaped bottles), due to the low cultural quality of employees, the technical content and artistic content of products are limited to a certain extent; At present, the technical level of the row and column machine operators is uneven, and there are a lot of people who know the forming process and the whole glass manufacturing process. The grade and price of products are up to 1million times, and the added value is not high. Enterprises urgently need to improve their internal skills, strengthen training, and comprehensively improve the technical level and quality of employees. According to the market demand, we should increase the variety of designs and colors, increase scientific and technological investment, and make great efforts in improving product quality and innovation, so as to improve the international market position of China's daily-use glass industry
