1. Characteristics and Usage
KXNR-400D melt flow rate meter is designed and manufactured according to GB / T3682, ASTM D1238, JB / T5456, ISO1133 standards for the determination of thermoplastic melt mass flow rate (MFR) and melt volume flow (MVR). . The mass flow rate of the melt is measured by manual and automatic sampling and the balance is weighed. The volume flow rate of the melt is measured by a displacement sensor and an automatic timing system. The time required for the piston to move a specified distance is measured first, and then calculated according to the formula Volume flow rate. The final results of the two determination methods are printed out by a micro printer.
The instrument uses color touch screen display, PLC microcomputer control, modular circuit, accurate measurement data, simple operation, intuitive and clear, stable and reliable performance. It is not only suitable for polycarbonate (PC), fluoroplastics, Engineering plastics such as nylon are also used for testing plastics with lower melting temperatures, such as polyethylene (PE) and ABS resins. They are widely used in plastics production, plastic products, petrochemical industries, as well as colleges, scientific research units, and commodity inspection departments.
