Munurinn á PPR og PVC rörum

Mar 17, 2022

Munurinn á PPR og PVC pípum er sem hér segir:

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. Mismunandi litir: PPR pípur og PVC pípur hafa mismunandi liti. PPR pípan úr pólýprópýlen efni hefur björt útlit og betri hörku. Samkvæmt því að bæta við litameistaralotu er hægt að framleiða aðrar litapípur; PVC rör eru að mestu mjólkurhvít, með gljáandi yfirborði, en engan þversnið, og efnið er tiltölulega viðkvæmt.

4. Mismunandi framleiðslukostnaður: Vegna efnis og veggþykktar eru framleiðslukostnaður og verð PPR rör og PVC rör einnig mismunandi. Almennt séð er verð á PPR rörum tiltölulega hátt.
