Precautions to use a transparent PU duct hose
In general, alcoholic liquid media such as liquor are mostly transported with PU food grade hose. However, in some special environments, silicone hose can be more better. So can silicone hose transport alcohol? Will chemical reactions occur? Will it affect the quality and life of the hose?
Silicone hose is suitable for most alcoholic liquids
Due to the material properties of silicone rubber, it will not react with weak acids, weak bases, and substances such as ethanol. Therefore, it can transport alcohol solutions without affecting the quality of the transported substances. Alcohol with a content of less than 70% can be transported with confidence. However, high-concentration ethanol solutions will accelerate the aging of silicone tube and shorten the service life.
Generally speaking, PU food grade hoses are mostly used to transport alcoholic beverages such as liquor, beer, and red wine. Large diameter hose has a great price advantage over silicone hose. However, some small diameter equipment needs silicone hose. Such as peristaltic pump, liquor filling machine, etc.
Since silicone materials have special physical and chemical functions, they are often used to transport various alcohols and lipids. However, as the temperature increases, the pressure resistance of the hose will be greatly reduced. At the same time, some materials that do not react at room temperature will also react at high temperatures.
