Tipy pro výběr vodního potrubí PPR

Právě si koupil nový dům, mnoho lidí je zaneprázdněno zdobením svého hnízdečka lásky. Jak vybrat správnou dýmku za správnou cenu je pro ně velmi důležitá věc. Následující triky vás naučí, jak rozlišit kvalitu PPR trubice.

1. "Touch": Whether the texture is fine and the particles are uniform. PPR tubes on the market mainly have several colors of white, gray and green. In general, recycled plastics cannot be made into white, so many people often think that white is the best. In fact, this view is relatively one-sided. With the update and improvement of technology, color is not the standard for distinguishing the quality of PPR tubes. Whether the tube is good or bad, it can't solve the problem. If you touch it, the rough particles are likely to be mixed with other impurities.

2. "Smell": with or without odor. The main material of PPR pipe is polypropylene. Good pipes have no smell, and bad ones have a strange smell. It is likely to be blended with polyethylene (ie PE) instead of polypropylene.

3. "Pinch": The PPR tube has considerable hardness, and it can be easily pinched into a deformed tube, which is definitely not a PPR tube.

4. "Smashing": A good PPR tube has good "resilience". It is too easy to smash because there are too many calcium carbonate fillers, which is naturally not a good PPR tube. An unbreakable PPR tube may not be a good tube. The key is to look at the raw materials and processing technology.

5. "Burning": It is very intuitive and effective to set it on fire. PPR pipes mixed with recycled plastic and other impurities in the raw materials will emit black smoke and have a pungent odor; good materials will not emit black smoke and odor after burning, and the molten liquid will still be very clean after burning.
