Recently, the extension of the coal Elm energy company PP2 device in K1860 based on the successful production of high-melting K1890 homopolymer products.
At this point, Elm can be 4 months in advance to complete the annual development of 13 new grade products plan. According to Elm Energy PP2 device responsible for the introduction, the conversion from z30s grade to K1890 grade products, although the two products are homopolymer, but between the melting point range of large span, to increase the difficulty of converting. The new grade K1890 's melting index is relatively high, before the conversion of equipment technicians fully demonstrated, and further optimize the extrusion section of the additive ratio, to overcome the high pressure of the reactor is difficult to control.
During the conversion, the installation technician tracking, carefully control the parameters, the same day 5 o'clock in the afternoon powder analysis qualified, marking the successful production of PP2 device K1890 grade products.
