LS-618 Minimum Film Forming Temperature Tester ISO 2115 ASTM D2354

LS-618 Minimum Film Forming Temperature Tester ISO 2115 ASTM D2354

Descrição：When emulsion polymer is used to produce paint, de um revestimento determinando a maior força de tração que ele pode suportar antes de se desprender, 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.

♦ O instrumento vem com dois modos de teste：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.

Minimum Film Forming Temperature Tester（MFTT）is the newest high-precision product which has been developed. 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 15^th e 16^th 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.

Está de acordo com a ISO 2115, ASTM D2354 standard, e pode testar a temperatura mínima do filme do polímero de emulsão com facilidade e precisão.
