锌合金是以锌为基础，并加入铝、铜、镁、镉、铅、钛等元素组成的合金。常 温下呈蓝白色，有光泽，质地硬脆。锌合金的熔点约为 380 摄氏度，浇筑温度 在 440~460 摄氏度之间。其优点包括熔点低、流动性好、易于焊接和塑形加 工，在大气中耐腐蚀，废料便于回收和重炉。然而，其蠕变强度低，易发生自 然时效引起尺寸变化。 2 号锌合金具有较高的强度和硬度，主要用于高强度操 作的工业配件及重力铸造。3 号锌合金满足一般物理和机械性能要求，是应用 最广泛的一种，占市场消费量超过 80%，适用于玩具、灯具、装饰品等对机械 强度要求不高的铸件。4 号锌合金主要应用于浴室配件、厨具和成衣拉链。5 号锌合金加入了约 1%的铜，提高了硬度和强度，但延展性较低，适用于汽车 配件、机电配件等对机械强度有一定要求的铸件。8 号锌合金普遍应用于高压 聚氯化铝市场方面，受成本、供应与需求多重因素影响，2025 年价格 整体呈现高位回落并区间整理趋势。短期内电厂停产消息带来看涨情绪， 但长期来看，供需失衡问题未解决，市场仍面临挑战。 2025 年硫酸铝市场下游需求平淡，以刚需为主，对传统行业支撑有限。 年底价格预计保持稳中微涨态势，上涨幅度约 ...

Core Viewpoint - The article highlights the transformation of Yishuiyuan Group from a small cement factory to a leading producer of water purification materials, leveraging technological innovation to utilize aluminum waste and achieve significant growth in the water treatment industry [9][10][11]. Company Development - Yishuiyuan Group has undergone a "triple jump" in development over 20 years, evolving from a struggling cement factory to a top player in the water purification materials sector [10]. - The company achieved a production value growth of approximately 15% year-on-year in the first half of the year, with an expected annual production value of 1.2 billion yuan [11]. - Yishuiyuan's production capacity for calcium aluminate powder is currently 500,000 tons, holding a 40% market share domestically and exporting to countries like Japan, South Korea, Russia, and South Africa [11]. Technological Innovation - The company has successfully developed a technology to use aluminum waste (aluminum ash) to replace bauxite in the production of calcium aluminate powder, significantly reducing production costs and environmental impact [12][14]. - This innovation has been recognized by ecological and environmental departments, allowing Yishuiyuan to produce eco-friendly water purification materials while lowering energy costs by 7%-8% and reducing pollutant emissions by about 5% compared to traditional methods [14]. Industry Positioning - Yishuiyuan is positioned as a key player in the energy-saving and environmental protection industry chain in Jiaozuo, contributing to the city's transition from a coal-based economy to a green development model [19][23]. - The company is set to become the largest aluminum-based new materials production base in the country, with a total investment of 10 billion yuan and projected annual sales revenue of 12 billion yuan upon completion of its industrial projects [18]. Future Plans - Yishuiyuan plans to expand its product lines and enhance its research capabilities through a new industrial park covering 800 acres, which will include a technology incubation center and various production projects [15][16]. - The company aims to further integrate renewable energy sources such as solar and wind power into its operations, striving to become a zero-purchase, zero-carbon enterprise [23].
