Pinch Tabung PPR memiliki kekerasan yang cukup besar, dan dapat dengan mudah dijepit ke dalam tabung cacat, yang jelas bukan tabung PPR.
Touch Whether the texture is fine and the particles are uniform. At present, PPR tubes on the market mainly have several colors of white, gray and green. Generally, recycled plastics cannot be made into white, so consumers often think that white is the best. In fact, this view is rather 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 seems that it can't solve the problem. If you touch it, the rough particles are likely to be mixed with other impurities.
Cium baunya. Bahan utama pipa PPR adalah polypropylene. Pipa yang baik tidak berbau, dan yang buruk memiliki bau yang aneh. Kemungkinan akan dicampur dengan polietilen, bukan polipropilen.
Burn Ini sangat intuitif dan sangat berguna. Pipa PPR yang dicampur dengan plastik daur ulang dan kotoran lainnya dalam bahan baku akan mengeluarkan asap hitam dan memiliki bau yang menyengat; bahan yang baik tidak akan mengeluarkan asap hitam dan bau setelah terbakar, dan cairan cair akan tetap sangat bersih setelah terbakar.
A good PPR tube has good "resilience", and it is not a good PPR tube if it is too easy to smash. However, strong hardness does not mean good elasticity. Consumers will have doubts about PPR tubes that cannot be broken. Because some unscrupulous manufacturers increase the hardness of pipes by adding too much calcium carbonate and other impurities, such pipes are prone to brittle cracks after a long time.
