zkoušečka indexu toku taveniny
Plastic lab melt flow rate index meter tester
Melt flow rate instrument is also called plastic, pryskyřičný index toku taveniny se používá pro měření rychlosti toku taveniny při hodnotě MFR stavu viskózního toku, platí pro polykarbonát, vyšší teplota aromatického sulfonu, fluor plastové, nylon a další technické plasty, can also be applied to polyethylene (PE), polystyren (PS), polypropylen (PP), ABS pryskyřice, polyformaldehyde (POM), polykarbonát (PC) resin with lower melting temperature, such as plastic test, široce používané při výrobě plastů, plastové výrobky, such as petroleum and chemical industry and related colleges and universities, vědecko-výzkumné jednotky, and the commodity inspection department
Typ:
1. The digital display
Set the electronic P.I.D regulator for temperature control, which is completely in line with national standards (cannot test melt volume flow rate and melt density).The machine also sets up the counter, which is convenient for measuring cutting time.The instrument works with the cutting and weighing method, and the scope is wide.
2. LCD is fully automatic.
Single chip microcomputer temperature control and program control, under test ended, and automatically display the time needed for a specific volume of the melt flows through the mouth mould, the calculation flow rate value, can repeat of high precision, easy to operate.The system is involved in temperature control.The manual cutting device can ensure the smooth detection by cutting and weighing method when automatic detection is not possible.Compact structure, beautiful shape, vysoká přesnost, easy to use accessories.
3. Microcomputer controlled automatic.
The melt indexer sets up a single chip microcomputer automatic test device and electronic automatic cutting device.After the microcomputer system has input the corresponding parameters from the light touch key, the test is finished, namely, automatic calculation and printing of flow rate value, high repeatability and convenient operation.The temperature control of the use of computer software technology, which can automatically eliminate because of the power supply voltage fluctuation and the influence caused by environmental changes, and when the temperature of the instrument and the standard temperature thermometer (special correction to match) appeared deviation, the operator can easily random fixed.The electronic automatic cutting device can be automatically cut at the preselected interval to calculate the final result when automatic detection is not possible.
hlavní aplikace:
Melt flow rate instrument, used to measure the thermoplastic resin melt mass flow rate (MFR), rychlost toku taveniny (MVR) objem a hustotu taveniny, it is not only applicable to the high melting temperature of polycarbonate, nylon, fluor plastové, aromatic sulfones engineering plastics, also applies to polyethylene, polystyren, polypropylen, ABS pryskyřice, poly formaldehyde resin with lower melting temperature, such as plastic test, widely used in plastic raw materials, products, petroleum and chemical industries, and related colleges and universities, scientific research units and the commodity inspection department.

How it works:
Melt flow rate meter is in the specified temperature conditions, with high-temperature furnace to melt the state of the measured object. The molten state of the measured object, the required weight load by gravity out of a certain diameter hole in the test. Plastics in industrial enterprises and scientific research units of production, often with “melt (mass) flow rate” to represent the polymer material in the molten state of fluidity, viscosity and other physical properties. Melt flow rate refers to the extrudate, the average quality of the sample paragraphs are translated into 10 minutes of extrusion volume. Melt (mass) flow rate expressed by MFR, jednotka: G / 10 minut (G / mě)
Formula: MFR (θ, mnom) = tref × m / t = 600 × m / T (g / 10 min)
Where: θ – zkušební teplota
mnom – Nominal Load Kg
m – the average quality of cut g
tref – reference time (10mě): 600
T – cut off time interval unit: sekundy.
Example:
A set of plastic samples, a cut every 30 sekundy, the quality of the results section: 0.081 G, 0.086 G, 0.081 grams, 0.089 grams, 0.082 grams.
Cut the average quality m = (0.081 +0.086 +0.081 +0.089 +0.082) ÷ 5 = 0.0838 ≈ 0.084 (G)
Into the formula: MFR = 600 × 0.084/30 = 1.680 (G / 10 mě)
