Matters needing attention and key points in purchasing PPR tubes:
The main purpose of touching by hand is to feel whether the texture is fine and the particles are uniform. Therefore, many people often think that recycling plastics is not white. Actually, this view is one-sided. With the improvement of technology, color is no longer the standard to distinguish the quality of ppr hot water pipes. Feel the quality of the pipe with your hands. If the particles are coarse, they are likely to be mixed with other impurities, which will threaten health.
When shopping, smell with your nose. The main material of Ppr hot water pipe is polypropylene. Good pipes are tasteless, and poor pipes have other smells. If there is an odor, it is probably mixed with polyethylene, not polypropylene. The hardness of Ppr hot water pipe is quite large, and it is easy to be pinched into a deformed pipe, which is definitely not a ppr hot water pipe.
A good ppr hot water pipe has a good "resilience", and it is naturally not a good ppr pipe if it is too easy to break. However, strong hardness does not mean good elasticity, and people will have doubts about how to break the ppr tube. Because some unscrupulous manufacturers improve the hardness of pipes by adding too many impurities such as calcium carbonate, such hot water pipes are prone to brittle fracture after a long time of use.
When buying hot water pipes, ignition is intuitive and useful. Ppr hot water pipes are mixed with impurities in raw materials such as recycled plastics, which will emit black smoke and have a pungent smell; Good materials will not emit black smoke and smell after burning, and the molten liquid will still be clean after burning.
