公司依托安徽皖维高新股份有限公司为生产基地，联合国内化纤及混凝土专业多家科研院校，对高强高模聚乙烯醇（PVA）纤维进行成功改性，使之在混凝土中能够均匀分散。并与中国水电成都勘测设计院一道，经过多次反复试验，成功取得改性聚乙烯醇纤维（MPVAF）在国内特大型水电站主体工程中的应用。
公司历年来先后为国内特大型水电工程提供改性聚乙烯醇纤维（MPVAF）产品，致力于解决混凝土抗裂、抗冲耐磨等常见问题，并以优良的质量及完善的技术服务赢得客户的一致好评，在行业中建立了稳固的领导地位。
千里之堤 毁于蚁穴。裂缝是混凝土常见病害，混凝土的裂缝成因复杂，各种因素相互影响。在内部应力、外部荷载、温度变化、收缩、基础变形、施工材料及工艺质量、钢筋锈蚀等因素作用下混凝土形成裂缝。尤其在水和海洋环境下，混凝土的开裂导致渗流通道相互连接并且增加混凝土的渗透性，这种由于裂纹扩张导致的渗透性的增加，使得更多的水和有害化学成分渗入混凝土中，引起混凝土性能的进一步劣化、开裂。这样一个链式反应： 劣化——开裂——可渗性增加——进一步劣化，终将导致混凝土结构的毁灭性破坏。
Slight negligence may lead to a great disaster. Cracking with different causes and interactive factors, which is caused under actions of inner stress, external load, temperature variation, contraction, foundation deformation, materials of construction, quality of process and corrosion of reinforcement, as well as other factors, is regarded as a common danger to concrete. Especially under water and marine environment, cracking of concrete will lead to integrated connection of seepage channels and extra intensity of permeability of such concrete, resulting in more water and harmful chemicals penetrating into the concrete and causing further degradation and more cracking. Such a chain reaction, defined as degradation—cracking—penetration increasing—further degradation, will definitely lead to catastrophic damage to concrete.
我们西南部水资源丰富，为我国发展清洁能源——水力发电提供了有利条件，十一五、十二五期间我国水电建设事业蓬勃发展，其中有多座200~300米级的混凝土大坝同时在建，高库大坝的质量安全是参建各方尤为关注的问题。
Water source in southwestern China proves rich and serves as a favorable condition for development of China’s clean energy—hydro power. During period of the eleventh and twelfth “Five-year Plan”, our hydropower construction career has seen flourishing development, during which, more than several concrete dams of 200 to 300m are in construction, and quality safety of dam for high reservoir is deemed a focus for construction participants.

两院院士、已故三峡工程咨询专家潘家琤先生对三峡集团公司的大坝建设提出了“零裂缝 零缺陷”的殷切希望，“双零”目标成为三峡集团追求细节完美、打造精品工程的独特企业文化。实践表明，只要防范措施得当，材料不断优化创新，双零目标是有可能实现的。在三峡集团公司溪洛渡和向家坝水电站等在建工程中，“无坝不裂”已经成为历史。
Pan Jiazheng (academician of the Chinese Academy of Sciences and Chinese Academy of Engineering) late consulting expert of Three Gorges Project, put forward a hopeful expectation of “Zero Cracking and Zero Defect” for the dam construction of China Three Gorges Corporation, which has served as a unique enterprise culture for Three Gorges Corporation in striving for perfect details and creating high-quality project. Practice shows that, the above “Two Zero” target can be realized by constant innovation and optimization of materials, and proper precautionary measures. During projects under construction such as Xiluodu Hydropower Station and Xiangjiaba Hydropower Station of China Three Gorges Corporation, the painful memory of “all dams with cracking” has already stepped into the history.
