    BASF Coolants General Presentation
    來源:濟南誠潤達貿易有限公司 發布時間:2021-12-01 13:56:15
    History of Coolant Base Fluid Development:/冷凍液基礎液的發展歷史:
     
    · Alcohols 醇    低沸點,易燃
    - Disadvantages: Low Boiling Point; Potential Fire Hazard
    · Salts 鹽    易致銹,易結晶沉淀
    - Disadvantages: Corrosiveness; Deposits by Cristallisation
    · Glycerine 甘油    粘度高,防凍差,與橡膠不相容
    - Disadvantages: High Viscosity; Less Freezing Protection; Incompatibility with Rubber Hoses
     
    The Solution: Mono Ethylene Glycol / 解決方法:乙二醇
    BASF Patent granted in 1929. Brand Name:Glysantin / 巴斯夫于1929年取得專利 商品名稱: GLYSANTIN
     
    Characteristics of Good Engine Coolants:/優秀發動機冷凍液的特點:
     
    · Prevention of Corrosion/防銹
    · Prevention of Cavitation/抗汽蝕
    · Prevention of Over-heating/防過熱
    · Excellent Heat Transfer/良好的導熱性
    · Stability at high Temperature/高溫穩定性
    · Compatibility with Hard Water/對硬水的高容忍性
    · Little Swelling of Rubber and Elastomeres/不會引起橡膠及高彈體的明顯膨脹
    · Low Foaming Tendency/低泡
    · Prevention of Deposits/防沉淀
    · Freeze Protection/防凍
     
    Basic Formulation of Coolants/冷凍液的基本組成:
     
    1. Base Fluid/基礎液(Mono EthyleneGlycol/乙二醇),> 90% + Additives/添加劑(Surface activeInhibitors prevent/表面活性抑制劑(Corrosion/防銹、Cavitation/防汽蝕、Deposits/防沉淀;Others/其他:pH Buffer/緩沖pH、Defoamer/消泡、Stabilizer/穩定)),5-7% + Water/水(as by-productsfrom components/反應副產品),3 - 5% = Coolant Concentrate/原液.
     
    2. Coolant Concentrate原液(30 – 60%) + Water 水(40 – 70%) = Coolant/冷凍液(ready to use/即用型).
