The development status, main technologies and characteristics of the glass deep processing industry
Glass deep processing products are made by secondary processing of flat glass, giving it special properties or functionsIt is widely used in construction, automobiles, photovoltaics, electronics, home appliances and other fields. There are a large number of domestic glass deep processing product manufacturers, with a high degree of marketization and competition It is more sufficient and less concentrated, and the market growth of low-end glass products is flat. The quality is uneven, and the overall is in a state of oversupply。
Glass deep processing products are mainly made of float and calendering The original film is reprocessed, and the gross profit margin and price of deep-processed glass of different enterprises vary greatly, mainly Due to the large number of types of glass deep processing products, the thickness, processing technology, quality requirements, and technical compounding degree of different types of deep processing glass are quite differentEnterprises in the industry need to have high-precision cutting, edging, drilling, and more Techniques such as lamination, color glaze, curved arcs, and multi-curved surfaces can meet complex shapesand high precision requirements for deep processing of glass.
At present, the domestic glass deep processing technology mainly includes three aspects:(1) embossing, etc Surface treatment technology, that is, the use of physical or chemical methods to process on the surface of glassvarious patterns and patterns; (2) CoatingTechnology, so that the glass deep processing products have increased transparencyAnti-fingerprint, anti-oil stain, sterilization, etcEasy to clean and other functions; (3) ForIt is required to manufacture glass products with multiple functions, such as thermal insulation, sound insulation, explosion-proof, etcIt is treated with composite processing technology (such as sandwiching, coating, hollow, vacuum, etc.). In addition, in order to reduce the impact on the environment, glass deep processing enterprises should also adopt low-energy consumption and low-emission manufacturingprocesses, such as energy-saving tempering furnaces, wastewater treatment systems, desulfurization, denitrification and dust removal system, etc.
Glass deep processing technology has a wide range of applications in the development of the national economy, involving industrial manufacturing, construction, automobiles, and photovoltaics, home appliances, home furnishings and other fields. The main characteristics of the glass deep processing industry are: (1) technologyIntensive: Glass deep processing involves a variety of processes, especially the research and development of high-end productsand production requires strong technology accumulation; (2) The application field is comparativeExtensive:The downstream demand of the industry is diversified, covering construction, automobiles, photovoltaics, electronics, etchome appliances and other fields; (3) RegionalStrong: the transportation cost of glass deep processing productsRelatively high, glass manufacturing and deep processing enterprisesSite selectionIt is usually close to the downstream market and is easy to form regional industrial clusters. (4) Product differentiationObvious: different application fields do not require glass performanceSimilarly, there are a wide variety of products and obvious differentiation, such as automotive glass pays attention to strength andLightweight, photovoltaic glass focuses on light transmittanceAs well as weather resistance, home appliance glass pays attentionShapeaesthetics and functionality; (5) Environmental protection requirements are relatively highHigh: Exhaust gas, wastewater and other pollutants will be produced during the deep processing of glassWith the continuous tightening of national environmental protection policiesindustryEnterprises need to increase investment in environmental protection; (6) Capital intensive: high-end glass deep processing production lines have a large investment and need to be comparedA large amount of capital investment.
The cyclical nature of the glass deep processing industry is closely related to the downstream industry, mainly affected by construction, automobiles, photovoltaics, and electronics, home appliances and other downstream industries demand fluctuations, raw material prices and the impact of the macroeconomic environment。 (1) When the macroeconomic boom or downstream industry demand is strong, the glass deep processing industryBenefit; (2) If the macroeconomy is sluggish or the demand of downstream industries decreasesAt that time, the glass was further processedIndustry productsSales also decreased, which was basically positively correlated with the economic development cycle, and the cyclical, seasonal and regional characteristics were not obvious.
At that time, our country's economy was in a period of transformation from high speed to high quality, and the market was interested in glass products The requirements for energy-saving performance, design novelty, process accuracy, and product quality have been further improved, making the domestic high-end deep-processed glass market demandKeep growing. With the improvement of technical level and changes in market demand, the glass deep processing industry It is moving towards high-end, intelligent and green direction, market share It is also constantly concentrated on advantageous enterprises with innovative production capabilities.
In addition, the state has introduced relevant policies to encourage the use of energy-saving and environmentally friendly materials to promote the glass deep processing industryIn the direction of high-end and green development, all levels Local governments support the construction of glass deep processing industry clusters through industrial policies. Therefore, enterprises in the industry need to diversify their layout, technological innovation, and cost controland international expansion and other measures to cope with cyclical fluctuations in the industryAchieve high quality and sustainability.
