Overview
The RONGJIDA QMB minimum film forming temperature (MFFT) tester is a testing instrument for measuring the minimum film forming temperature (MFFT) of polymer emulsion. The instrument is designed and manufactured according to the standard GB/T9267 and ISO 2115-76. The Temperature range is 0~ 45 degrees Celsius. It uses digital display to display the test results. It has simple, intuitive and accurate characteristics and is widely used in Coatings, gluing agents, chemical fiber fabrics, leather, paper and other fields.
Features
1. Designed and manufactured according to GB/T9267 and ISO 2115-76 standards.
2. Temperature range is 0~ 45 degrees Celsius.
3. The test results are displayed digitally and accurately.
4. Easy to operate.
Principle
The Working Principle of the QMB minimum film forming temperature (MFFT) tester is to set the cooling source and the heating source respectively on a suitable metal plate and keep them at the thermostatic point of their set temperature. Through the principle of metal heat conduction, different temperature layers are generated on the metal plate. Spreader a sample of uniform thickness on the temperature layer plate, and the temperature on the sample receiving layer plate evaporates water and films formation. The phenomenon of sample film formation is also different due to the different temperatures on the plate layer. Finding the dividing line part is the MFT temperature of the sample.
Applications
Coatings, gluing agents, chemical fabrics, leather, paper
Standards
GB/T9267、ISO2115-76
Steps
1. Spreader samples of uniform thickness on the layered plate.
2. The sample layer plate temperature evaporates water and film formation.
3. Observe the film formation phenomenon in different temperature regions on the layer plate.
4. Find the dividing line between film formation and unformed film, and the temperature corresponding to the dividing line is the minimum film forming temperature (MFFT) (MFT) of the sample.
Notice
• Ensure that the layer plate temperature is stable at the set value.
• Spreader samples to ensure uniform thickness.
• Careful and accurate observation of film formation boundaries.
