1、 Purpose:
XNR—400DThe melt flow rate meter meets the requirements《GB/T 3682The standard "Determination of Mass Flow Rate and Volume Flow Rate of Thermoplastic Melt" is used to determine the flowability of thermoplastic polymers at high temperatures, such as polyethylenePEPolypropylenePPResinABSPolycarbonatePCNylonPA6Measurement of the melt index of various plastic raw materials. the productWidely used in industries such as plastic raw material production plants, plastic product factories, petrochemical companies, as well as relevant colleges, research institutes, and quality inspection units.
2、 Characteristics:
1.This instrument adoptsPLCControl7Chinese character display and touch operation on inch touch screen.
2.Automatic temperature control: using DeltaPT1000VAutomatic control modulePIDControl, fast constant temperature, small temperature fluctuations.
3Automatic cutting: There are two cutting operation modes: "timed cutting method" and "positioning and moving cutting method".
3．1The "timed cutting method" starts the automatic cutting of the test system after inputting the cutting cycle. At the end of the test, it automatically switches to the result screen and displays the volume method result. Simply input the total weight of the effective section, and the system automatically calculates the quality method result and melt density.
3.2After entering the number of cutting ends, the "positioning and cutting method" starts the automatic cutting of the test system. At the end of the test, it automatically switches to the result screen and displays the volume method results. Enter the weight of each effective section, and the system automatically calculates the quality method results and melt density.
4Can measure the melt density of high flow rate materials separately: High flow rate meltblown materials cannot be cut and weighed for each section, and can only be automatically converted from the melt density and volume method results to the mass method results
5.Local automatic loop storage is the most recent10This is a historical record that can be queried and printed.
6Comes with micro printing function
