Full Load Melt Flow Index Tester , AC220V 50Hz Rubber Testing Machine

Brief introduction

1.Purpose:

Melt flow rate tester (also known as melt index meter) was measured under certain conditions thermoplastic melt flow rate of the special equipment. With the determination of melt flow rate MFR, measured melt volume rate MVR, measured melt density ρ, measured melt flow rate ratio FRR and other functions, this machine high precision temperature control, key parts nitriding treatment, high strength and hardness , small deformation accurately measure the flow rate which provides a good condition.

2.Principle:

Thermoplastic melt flow rate (melt index) is plastic at a temperature and load, the melt every 10 minutes through a standard capillary die quality or melt volume, with MFR (MI) or the MVR value, which can distinguish thermoplastic adhesive in the molten state flow characteristics. For thermoplastics and chemical fiber raw materials, quality assurance of products and other products of great significance.

3.According to the standard:

This instrument reference standards: ISO 1133, ASTM D1238, JIS-K72A, GB/T3682, JB/T5456, JJG 878

4.The main technical parameters:

5.Instrument structure:

The instrument consists of a cylinder, the piston rod, die, temperature control system, load, automatic test bodies and automatic cutting and other components. The figure below shows an external view of the product.
1) barrel
Using nitrided steel materials, and after nitriding production, Vickers hardness HV ≥ 700.
2) the rod (rod)
Using nitrided steel materials, and after nitriding production, Vickers hardness HV ≥ 600, the head smaller than the barrel diameter evenly 0.075 ± 0.015mm, top with an insulating sleeve, the rod and load insulation. In the feed rod with two engraved lines 30mm apart as a reference mark, their position is this: When feeding head under the top edge of the die apart 20mm, the tag line coinciding with the barrel mouth flat (see Figure 2).
3) the die
Die Φ2.095 ± 0.005mm, Φ1.180 ± 0.010mm (non-standard configuration) Vickers hardness HV ≥ 700.
4) the temperature control system
The system uses for platinum resistance temperature sensor, AL808 control instruments as a temperature controller, which uses PID control, can automatically compensate for supply voltage fluctuations and ambient temperature influence on the temperature control.
5) the load
Load is the weight and quality of the material and rod assembly. The quality and test load weight distribution tables:

* Mass rod assembly, the quality of the positioning sleeve is not included.
** The load will be charged with weights.
