Developing shelves with higher corrosion resistance has always been the goal of warehouse workers, based on traditional processes.On this basis, special steel materials with addedAlMgNiCrand other alloys, surface treatment processes, and supporting accessories were selected for research.The corrosion-resistant shelves from Haigelis, adding

 

MgAlNiCrand other alloy special steel materials in corrosion-resistant products can be traced back to the early 20th century, with the main purpose of further improving the corrosion resistance of steel plates.The surface treatment of corrosion-resistant shelves plays a crucial role throughout the production process, including pre-processing before machining, equipment debugging during processing, post-processing after machining, strict control of surface passivation treatment, and coating methods, ensuring the corrosion resistance of shelf products.21 The use of some supporting accessories during the installation process of shelf products also guarantees the corrosion resistance of the products to a certain extent.This type of corrosion-resistant shelf material has better corrosion resistance, and within a certain range, an increase in content makes the steel plates several times to over ten times more corrosion-resistant than ordinary plates.Due to the corrosion treatment before, during, and after machining, the raw materials are always kept in an isolated state, and finally, the choice of corrosion-resistant coatings and special process treatments ensure that the corrosion resistance of the materials is significantly better than traditional products.

 

 

The application of corrosion-resistant shelves in the hazardous waste treatment industry has greatly reduced the investment costs of fixed assets for hazardous waste enterprises, while also reducing the management and time costs incurred by enterprises due to shelf replacement.AlNiCrand other alloy special steel materials in corrosion-resistant products can be traced back to the early 20th century, with the main purpose of further improving the corrosion resistance of steel plates.The following are the actual measurement data of the products.Ordinary platesCorrosion-resistant materials

 防腐蚀材料的耐酸性和耐碱性比镀锌更优异

  防腐蚀原材料的使用为货架的耐腐蚀性打下了坚实的基础,但是对于防腐蚀货架的成型只完成了第一步,产品机加工过程中的防腐措施同样非常重要,我公司防腐产品严格控制加工过程中对基材的保护,使基材保持一个与外界物质隔绝的状态。 机加工完成后产品的前处理工艺既保证基材表面的洁净又可以在基材表面形成一层致密的保护膜,这层保护膜在涂装前起到隔绝外界的污染物质同时起到帮助涂层吸附的作用。针对涂层密封的问题,我公司产品采用高耐腐蚀性涂料二次涂装的工艺,大大提高了涂层的密封性。 安装过程中使用的防腐配套附件以及使用后日常的运维保证了产品的耐腐蚀能力。

针对客户设立专门的客户经理团队,成立包括销售、研发、安装调试和运维服务团队。针对质量管控、生产排产以及产品发运安排专人负责跟进。 客户服务团队每年至少走访一次客户,及时了解产品使用情况及用户在交付、质量、运维等方面的诉求。 用户在产品使用过程中发现问题或者提出异议,承诺24小时内到达客户现场,48小时内形成处理方案。

与危废处理企业联合进行了防腐材料代替Q235、Q345后浸镀锌的论证设计, 加工过程中的防腐处理以及涂料选型的论证设计,满足危废处理行业高耐 蚀、规范化管理的需求。应用于国内危废处理行业知名用户。

防腐货架广泛应用于华北制药、蓝润化工等化工龙头企业。 通过全球排名首位的汽车零部件企业---博世集团的体系认证审核。 通过了辛集皮革行业协会的认证,和森士隆、宏四海、瑞泰等国内知名制革厂进行了先期试验认证。
