Problems solved by technology

[0002] Compared with PE pipes, PVC pipes have better tensile and compressive strength, excellent corrosion resistance and lower price. They are suitable as communication pipes, but they are prone to brittleness during use, which affects their service life.
In order to ensure the permanence of the toughness of PVC pipes, PVC pipes need to be modified. If only a certain type of elastomer or a certain type of rigid body is used for toughening, it will cause an imbalance in the performance indicators of toughness, stiffness, and elastic modulus. Therefore, it is manufactured It is the main technical problem at present to maintain high strength while resisting impact and cracking, and to have good corrosion resistance.
