Application: melt flow rate test this instrument is not only suitable for testing polyethylene, polypropylene, polystyrene, ABS resin and other plastics with lower melting temperature, but also for testing polycarbonate, fluoroplastics, nylon and other engineering plastics with higher melting temperature

Melt flow rate test standard:

According to GB/T 3682-2000 thermoplastic melt mass flow rate and melt volume flow rate Determination, ISO 1133-2005 Plastics-Determination of the melt mass-flow rate(MFR) and the melt volume-flow rate(MVR) and other standards designed and manufactured for the Determination of thermoplastic melt flow rate instrument.

Model csi-f686 is standard configuration, using quality test method, automatic scraping material (manual scraping material can also be used when the instrument is adjusted), the spline weight can be recorded into the instrument system to automatically calculate the results, and the test records can be saved for future reference, at the same time, it is equipped with a full set of weights and all relevant accessories (electronic scale is optional). Based on csi-f686, csi-f686 is equipped with a miniature printing device, which can print any existing test records in the form of supermarket receipts with very detailed printing contents. On the basis of csi-f686 type, melt density test and volumetric test mode are added, which makes the function more powerful and advanced.

User guide:

If you are using this kind of instrument for the first time, you can directly consult our technical staff, who will guide you through the whole process (from the name and function of accessories to all steps of the test, and then to the cleaning and maintenance of the instrument and matters needing attention). Out after opening the instrument, and its related accessories on the test bench, the anchor installation, by adjusting the anchor to instrument level state, the mouth will die into the material at the bottom of the cone zui, set temperature and test related parameters, after reaching the temperature of the set and keep constant temperature, the plastic particles under test through the funnel and feed screw feed tube, put the piston rod in again, will be stipulated by the load (weights) pressure on the piston rod, for piston rod drop to calibration, click on the "test" button start timing blanking, after the test, will be cut by the plastic spline weighing and saved to the instrument, the instrument will automatically calculation, and saved as a result, Convenient for future reference, at the same time, it can also print the recorded test records.
