Can PVC pipes be used with drinking water?
At present, the domestic PVC processing is good and bad, there may be lead salt as a stabilizer for the water supply pipe.It is safe to use PVC water pipes that are not guaranteed by lead salts as stabilizers. Its physical and chemical properties still have advantages in plastic pipes.
PVC is for heat sensitive plastics, PVC, when processing products must be added to the forming of heat stabilizer.At present, the main types of heat stabilizers are lead salt stabilizer, organotin stabilizer and calcium zinc composite stabilizer.As the lead salt stabilizer has great advantages in stability and cost, it has always been the first choice of heat stabilizer for PVC products,
To put it simply, the lead in PVC plastics comes mainly from the heat stabilizer, lead salt. PVC water pipes containing lead salts, in the process of using heavy metals lead to precipitate from the pipe into the water, causing pollution.
