Calculate the Melt Flow Index of Plastics Using Correct Methods
Plastics are one of the most extensively used materials in the industries as well as for the domestic applications. The intrinsic properties of plastics make them useful for many applications where conventional materials cannot be used. As the plastic materials are used for many different intense applications, it is essential that the quality assessment of the materials as well as the products is done rigorously and thoroughly so that the best level of performance and safety could be ensured. The melt flow index is one of the most important properties of a plastic that help in studying the behaviour and the molecular structure of the polymeric materials and helps in enhancing the quality of the products with better analysis. The manufactures must ensure that they choose the best materials and that could only be done with the help of melt flow index testing through proper standards and methods.
Utilizing standard test method and conditions to perform MFI test on plastic granules is the most ideal approach to decide the physical just as synthetic properties of the material. Pacorr comprehends the requirement for estimating MFI of polymer granules and offers an excellent Melt Flow Index Tester. The testing instrument is ergonomically planned remembering the specific public and worldwide standard test strategies like ASTM D1238 – 13, ASTM D2839 – 10, IS 2530 (1963), IS 10810-1984 (Part 23), IS 2267 – 1995, and so forth The instrument is collected utilizing most recent innovation based advanced highlights, for example, PID regulator that assists with controlling the temperature inside the chamber with high exactness, a computerized clock to set the test time as long as 999 hours, a programmed shaper that cut the melted example after a time frame naturally and some more.
Utilizing profoundly state sanctioned testing machine isn't the main answer for register the quality or evaluation of granules. To discover the quality, it is important to adhere to standard working system. Underneath referenced are a few stages that help to figure the MFI of plastics in profoundly fitting way.
SOP for Melt Flow Index Tester
1. First of all turn the machine on by stopping the mains attachment of the machine into a 3 pin 15 amp attachment.
2. Set the SV esteem on the PID regulator and the test span timing on the computerized clock.
3. Switch on the flip changes from the control board for programmed cutting of test.
4. After setting the temperature and clock, turn the warmer on by squeezing the radiator on the switch.
5. Wait for the perusing in the PV show in the PID regulator to arrive at the estimation of the SV show.
6. After the necessary temperature for the test has been achieved, fill the barrel of the machine with the plastic granules you need to test.
7. Poke the granules with the unclogger after they are embedded into the barrel to guarantee close pressing of the granules and kill the air between the granules.
8. When the granules are embedded in the barrel, there will be a slight lessening in the PV esteem on PID screen. Sit tight for this incentive to again arrive at the SV esteem.
9. Once the PV and SV esteem are the equivalent, place the unclogger gave the machine alongside the dead weight on it into the barrel.
10. After position of unclogger, melted plastic emerges from the barrel.
11. When the time cycle on the computerized clock finishes, the shaper will naturally cut the example from the barrel.
12. Weigh the melted example utilizing an advanced equilibrium. This weight will be utilized for computing the Melt Flow Index of the example.
The formula for calculation of MFI:
MFI = Weight of test in grams/10 min.
With the accurate determination of the melt flow index of a material, it becomes very easy to analyse the quality and physical properties of a material which in turn helps in ensuring the best quality of products to the customers.
Thanks to Pacorr Testing instruments, we have all the required quality testing instruments that have helped us to ensure the best quality delivered to our clients.
