Method and its application in hdpe pipe.
Background technology
High density polyethylene (HDPE) is a kind of opaque white color waxy material, and high density polyethylene (HDPE) proportion is lighter than water, and has
Acid and alkali-resistance, organic solvent-resistant, case hardness, tensile strength and rigidity etc. the good advantage of mechanical strengths and be used widely, but
Be at the same high density polyethylene (HDPE) also have it is yielding, it is easy to aging, the characteristics of easy embrittlement.
In order to reduce the coarse whiting or fine particle calcium carbonate that cost usually adds different content when enterprise produces HDPE municipal administration pipes, cause to give birth in this way
The problems such as HDPE municipal administration pipe toughness and low ring stiffness of production, limit its industrial applications.Ultra-fine phosphogypsum powder is five big
One of gel rubber material, asepsis environment-protecting is cheap, is a kind of important industrial raw materials.If can be taken with ultrafine gypsum
For coarse whiting or fine particle calcium carbonate, while the mechanical performance of tubing is not reduced, there will be larger market prospects.
Therefore, it still needs to seek a kind of high density polyethylene (HDPE) master batch and tubing that ultra-fine phosphogypsum powder is modified.
