Agricultural rigid PVC thin-walled pipe and its production process, the formula of the agricultural hard PVC thin-walled pipe consists of the following amount of raw materials:
100 parts (SG-5 type) PVC resin,
0.4 — 0.6 parts T-175,
0.6 — 0.8 parts calcium carbide,
1.0 — 1.2 parts paraffin,
0.1 — 0.2 parts oxidized polyethylene wax,
1.0 — 1.5 parts titanium dioxide and
3.0 — 4.0 light calcium carbonate.
Its processing method is raw material mixing – hot mixing – cold mixing – extrusion – pipe shaping, cooling – pipe traction – cutting – finished product above steps. The agricultural hard PVC thin-WALLED pipe made by this processing technology not only has good low-temperature toughness, rigidity, ring stiffness and creep resistance, but also will not be deformed by gravity in the long-term use process, thus extending the service life of the product and contributing to the popularization of wide range.
