PVC hose for industrial and food grade use.
The hose we usually use is also PVC plastic hose, but it does not taste, while the industrial grade PVC steel hose, in order to increase pressure, use steel wire, of course, if larger and thicker, or black is the steel belt corrugated pipe or steel belt sewage pipe. Industrial and food grade hoses are different.
Lead salts stabilizer will be added to PVC steel hose for industrial use, while lead is toxic to human body; heavy metals will be released into drinking water and endanger human health; PVC is also called polyvinyl chloride, and chlorine element is harmful to human body. Therefore, PVC steel wire hoses can not be used for drinking water transportation.
The main flavor of industrial PVC steel hose is volatilization of PVC plasticizer, and hose plasticizer is dioctyl ester, dimethyl ester, etc. This kind of plasticizer contains benzene, which has the risk of carcinogenesis in such environment for a long time, but we should pay attention to it. Food hygiene grade PVC steel wire hose is non-toxic and harmless, and ventilation can be increased when used normally.
