        戊烷系統
         
        根據1989年發表的《關于耗損臭氧層物質的蒙特利爾議定書》,歐洲和美洲已經停止使用氯氟碳化物。自1993年以來,環戊烷在歐洲被認為是氯氟碳化物的替代品。目前,中國、印度、阿聯酋和其他發展中國家正在逐步淘汰氟氯化碳/氟氯烴。以戊烷為發泡劑的發泡體系,需要考慮以下因素:
        7.戊烷儲料系統
        戊烷儲存輸送系統主要用于存放槽車卸載的環戊烷,并自動實現向發泡機供料。由于戊烷蒸汽易燃易爆,因此該系統必須嚴格按照相關標準。
        戊烷儲料系統包含:料罐本體,戊烷輸送系統,罐體呼吸系統,液位系統,卸料系統,戊烷檢測系統。
        8.戊烷發泡系統
        發泡機上所有戊烷相關部件和管路均安裝在一個小房間內,房間內設有探頭和雙排氣系統以確保安全。檢測頭安裝在儲料罐上。
        安全系統由獨立的電氣柜控制,獨立于操作柜。
        9.戊烷安全系統
        戊烷檢測裝置將安裝在戊烷泄漏區和可能的泄漏區,包括履帶機和布料區以及儲料罐。幫助客戶安全可靠地運行生產線。
         
        主要成就
         
        威華是唯一一家中標聯合國戊烷連續發泡機項目的中國公司(參考中標文件)。我們掌握了戊烷儲料、運輸、混合、安全等技術,并于2014年投入實際生產。我們不僅提供設備,還為客戶提供建立員工培訓機制、操作規程、崗位泄漏預警機制等一系列服務,實現從機器到人員的100%安全。
         
         
        威華最新產品:聚氨酯夾芯板生產線四組分發泡機,交付國內領先的夾芯板生產企業多維集團。MDI的流動精度為1‰,混合物為1‰,催化劑為1‰,發泡劑為5‰。

        According to Montreal Protocol on Substances that Deplete the Ozone Layer published in 1989, Europe and America have ceased the use of CFC. Cyclopentane is considered as a replacement of CFC in Europe since 1993. and Now the progress to phase out CFC/HCFC is ongoing in China, India, UAE and other developing countries. For foaming system with pentane as foaming agent, the following factors need to be considered:

        1. Pentane Storage System

        Cyclopentane storage system is mainly used for storing cyclopentane which is unloaded from tank truck and then feeding the material to foaming machine automatically. The design, operation and safety of the system strictly conforms to the TUV standard.

        2. Pentane Foaming Machine

        PENTANE SYSTEM

        All pentane-related components and pipelines on the foaming machine are installed in one small room where probe and double exhaust system are equipped to ensure the security. A detection head is installed on the storage tank.

        The security system is controlled by independent electrical cabinet which is separate from operation cabinet.

        3. Pentane Security System

        Pentane detection devices will be installed in the pantane leakage zone and possible leakage zones, including double belt conveyor and material spraying area and material storage tank. Besides these, WEIHUA will offer below services which helps customer run this line safely and reliably.

        PENTANE SYSTEM

        Weihua is the only Chinese company that has won the bid for the UN pentane continuous foaming machine project (Refer to the winning bid). We have mastered the technology regarding pentane storage, transportation, mixing and safety, which has been put into practical production in 2014. We not only provide equipment, but also offer customers a series of services such as establishing staff training mechanism, operating rules and regulations, and post-leakage warning mechanism, so as to achieve 100% security from machine to personnel.

        Weihua latest product: four-component foaming machine for Pu sandwich panel production line, delivered to Duowei Union Group which is the leading panel manufacturer in China. The flow precision of MDI is 1‰, mixed Poly is 1‰, Catalyst is 1‰, foaming agent is 5‰.
