On April 2nd, Dushanzi Petrochemical Company successfully completed the conversion of 5000 tons of polyethylene floor heating pipe material DGDZ-3606. This conversion achieved continuous switching from UHXP-4808 to DGDZ-3606 under the first condensation mode.
Converting the condensing mode to production, it is necessary to avoid excessively high isopentane concentration, resulting in stickiness of the material, but also to make the condensation rate meet the requirements, to ensure that the ability of the reactor to remove heat meets the production requirements. The workshop management technicians have carefully compiled according to the 2017 production experience. Transferring the production plan, discussing the operation card with the patent owner one by one, determining the operation sequence, parameters and operating range, and controlling the overall process.
DGDZ-3606 is used for floor heating pipe production. It is a kind of medium density polyethylene produced by special molecular design and synthetic technology. It is also special material for PERT. It has good flexibility, high thermal conductivity and inertness, and can be used for a long time. Hot water delivery below 60 degrees Celsius. Simultaneous pressure resistance, low temperature resistance, non-toxic, odorless, non-polluting, green, recyclable, hot melt connection, installation, easy maintenance. At present, the market demand is large, but There is no domestic large-volume, high-quality manufacturer, and the source of supply is mainly imported. The market prospect is very broad.
