    戊烷系统
     
    根据1989年发表的《关于耗损臭氧层物质的蒙特利尔议定书》,欧洲和美洲已经停止使用氯氟碳化物。自1993年以来,环戊烷在欧洲被认为是氯氟碳化物的替代品。目前,中国、印度、阿联酋和其他发展中国家正在逐步淘汰氟氯化碳/氟氯烃。以戊烷为发泡剂的发泡体系,需要考虑以下因素:
    7.戊烷储料系统
    戊烷储存输送系统主要用于存放槽车卸载的环戊烷,并自动实现向发泡机供料。由于戊烷蒸汽易燃易爆,因此该系统必须严格按照相关标准。
    戊烷储料系统包含:料罐本体,戊烷输送系统,罐体呼吸系统,液位系统,卸料系统,戊烷检测系统。
    8.戊烷发泡系统
    发泡机上所有戊烷相关部件和管路均安装在一个小房间内,房间内设有探头和双排气系统以确保安全。检测头安装在储料罐上。
    安全系统由独立的电气柜控制,独立于操作柜。
    9.戊烷安全系统
    戊烷检测装置将安装在戊烷泄漏区和可能的泄漏区,包括履带机和布料区以及储料罐。帮助客户安全可靠地运行生产线。
     
    主要成就
     
    威华是唯一一家中标联合国戊烷连续发泡机项目的中国公司(参考中标文件)。我们掌握了戊烷储料、运输、混合、安全等技术,并于2014年投入实际生产。我们不仅提供设备,还为客户提供建立员工培训机制、操作规程、岗位泄漏预警机制等一系列服务,实现从机器到人员的100%安全。

    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‰.
