PPRパイプとPVCパイプの違いは次のとおりです。
1. The essence is different: PPR pipe is also called three-type polypropylene pipe. It uses random co-polymerized polypropylene to be extruded into pipes and injection molded into pipe fittings; while PVC is actually a vinyl polymer, and its material is an amorphous material.
2. Different properties: PPR is a new generation of pipeline materials in the late 1980s. The gas phase co-polymerization process is used to make about 5 percent PE randomly and uniformly polymerize (random co-polymerization) in the molecular chain of PP to become a new generation of pipeline materials. It has good impact resistance and long-term creep properties. PVC has strong resistance to oxidants, reducing agents and strong acids. It can be corroded by concentrated oxidizing acids such as concentrated sulfuric acid and concentrated nitric acid, and is not suitable for contact with aromatic hydrocarbons and chlorinated hydrocarbons.
3.異なる色：PPRパイプとPVCパイプは異なる色を持っています。 ポリプロピレン素材のPPRパイプは見た目も明るく、靭性も優れています。 カラーマスターバッチの追加に応じて、他のカラーパイプを製造することができます。 塩ビ管はほとんど乳白色で、表面は光沢がありますが、断面はなく、素材は比較的壊れやすいです。
4.製造コストの違い：材料と壁の厚さにより、PPRパイプとPVCパイプの製造コストと価格も異なります。 一般的に、PPRパイプの価格は比較的高いです。
