Minimum Film Forming Temperature Tester MFFT Test MachineMinimum Film Forming Temperature Test Equipment
Minimum Film Forming Temperature Tester /MFFT Test Machine/Minimum Film Forming Temperature Test Equipment
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 MFT temperature.
Tester Principle: Set a cooling source and a heating source on a suitable metal board and keep them at a constant temperature to the set 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 a film. The form of film performance is different under different temperatures. Find the boundary and then its corresponding temperature is the MFT temperature of this sample.
Minimum Film Forming Temperature Tester(MFTT)is the newest high-precision product that has been developed. We use platinum resistance imported from Germany as a temperature sensor, and use LU-906M intelligent temperature controller which combines fuzzy control theory with PID control, ensuring it shows an error less than 0.5%±1 bit. In order to reduce the size, we use a special size grad board at all costs. Furthermore, there is a 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 the 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 the operator judge the MFT point successfully, we design a clear and high graduated scale in the front of the working table.
It is in accordance with ISO 2115, ASTM D2354 standard, and can test the minimum film temperature of emulsion polymer easily and accurately.
Advantages
A wider working table can test 6 groups samples at the same time.
Space-saving desktop design.
Advanced design for grad board decreases the machine size.
Surface temperature is calibrated precisely, ensuring accurate and reliable data with a 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
