MFFT Testing Machine Low Temperature Film Forming Instrument Minimum Film Forming Temperature Tester
Description:When emulsion polymer is used to produce paint, adhesive, chemical blended fabric, surface treatment agents for leather or paper, its film forming property is very important. Apply an emulsion polymer or emulsion paint on the metal board, when the water has been evaporated, polymer particles would form a continuous and transparent film because of interaction under suitable temperature. The ultimate temperature of critical film forming is called as minimum film forming temperature for this emulsion polymer, short for MFFT temperature.
ASTM D2354 Minimum Film Formation Temperature(MFFT) Tester
Tester Principle:Set a cooling source and a heating source on a suitable metal board and keepthem at a constant temperature to setting point. Different temperature grads would appear on this board because of metal heat conduction. Paint uniform thickness sample on this temperature grads board, the water of sample will be evaporated under heating of different temperature and sample will form film. The form film performance is different under different temperature. Find the boundary and then its corresponding temperature is MFT temperature of this sample.
MFFT Testing Machine Low Temperature Film Forming Instrument Minimum Film Forming Temperature Tester
Minimum Film Forming Temperature Tester(MFFT)is the newest high-precision product which has been developed by Biuged. We use platinum resistance imported from Germany as temperature sensor, and use LU-906M intelligent temperature controller which combine fuzzy control theory with PID control , ensure it shows an error less than 0.5%±1 bit. In order to reduce size, we use special size grad board at all costs. Furthermore, there is water-break protection system for any water break, the machine will turn off automatically once there is water-break. For saving water consumption, we let tester screen show cooling water temperature (on the 15th and 16th point of inspection recorder), decrease the water consumption as far as possible(by hand) according to different settings. In order to let operator judge MFT point successfully, we design clear and high graduated scale in the front of the working table.
It is accordance with ISO 2115, ASTM D2354 standard, and can test minimum film temperature of emulsion polymer easily and accurately.
Advantages
Wider working table, can test 6 groups sample at the same time.
Space saving desktop design.
Advanced design for grad board decreases the machine size.
Surface temperature is calibrated precisely, ensuring a accurate and reliable data with temperature scale .
Intelligent temperature controller, ensures error is less than0.5%±1 bit.
Cooled by semiconductor and big power switching voltage decreases noise from cooling system considerably
