Description
Technical field
The invention belongs to plastics preparation technical fields, and in particular to a kind of corrosion-resistant, high-strength plastic of sewage sewer pipe
The preparation of material.
Background technique
China's municipal drainage pipeline mainly uses pipe of concrete in the past, because its rigidity is good, ring stiffness is higher, has good
Mechanical property and durability.But concrete plug has the shortcomings that much itself is unconquerable: upstream link cement industry is to ring
Pollution caused by border is extremely serious, and production and processing energy consumption is high, waste of resource；Transport is inconvenient, inefficiency；Quality of connection is poor, easy
Leakage, polluted underground water；Smoothness is poor, and energy consumption is high for water delivery；Corrosion resistance is poor, and shock resistance and anti-deformation are poor, and the service life is short.
Compared with traditional cement concrete pipe, cast iron pipe, clay pipe etc., plastic tube not only complies fully with the requirement of drainage pipe, and
And have more excellent physical and chemical properties: light-weight, shock resistance and tensile strength are high, and corrosion resistance is preferable；Inner surface
Coefficient of friction is small, and water delivery energy consumption is small, and leakage is few, and synthesis energy saving is good；With certain flexibility, convenient transportation, installation is simple；
