Low temperature film-forming temperature measuring instrument

Low temperature film-forming temperature measuring instrumentIt is mainly used to test the low film forming temperature of polymer lotion. In addition to being widely used in the coatings industry, it is also applied in many industries that require temperature gradient testing, such as latex, adhesives, plastics, inks, food, cosmetics, and chewing gum; Packaging paper, adhesives, tapes, heat transfer tapes, etc.

Low temperature film-forming temperature measuring instrumentPrinciple:

On a suitable metal plate, separate cooling and heating sources are set up and maintained at their set temperature constant points. Through the principle of metal heat conduction, different temperature gradients are generated on the metal plate. Coat a uniformly thick sample on the temperature gradient plate, and the sample forms a film by evaporating water at the temperature on the gradient plate. The phenomenon of sample film formation varies due to different temperatures on the gradient plate. Finding the boundary section is the MFT temperature of the sample.

This instrument is a better measuring instrument in China at present, which can measure the low film forming temperature of polymer lotion simply, intuitively and accurately.

Execution standards: GB/T9267-2008 and ISO2115-76 standards

It is used to measure the low film forming temperature of polymer lotion. When polymer lotion is used as a surface treatment agent for coatings, adhesives, chemical fiber fabrics, leather and paper, its film forming property is one of the important properties. The polymer lotion or emulsion paint is coated on the metal plate. After the water evaporates, the polymer particles interact to form a continuous transparent film at a suitable temperature. The critical film forming temperature is called the low film forming temperature of the polymer lotion, or MFT temperature for short

The low film-forming temperature tester has the following advantages:

A. By using semiconductor refrigeration devices and new environmentally friendly insulation materials, the insulation installation process has been changed, allowing the refrigeration end to operate at a low temperature of -10 ℃ or even lower;

B. Imported intelligent temperature control meter heads are used for temperature control, making PID control parameter self-tuning more intelligent and achieving higher success rates. The temperature control accuracy is higher and the control is more stable. The temperature control deviation at the refrigeration end is within 0.3 ℃, and the temperature control deviation at the heating end is within 0.5 ℃;

The low film-forming temperature measuring instrument adopts a contactless control method, which improves the temperature control accuracy and sensitivity, and extends the working life of the measuring instrument. D, Stainless steel casing.

The automatic low film forming temperature tester can measure the low film forming temperature of polymer lotion simply, intuitively and accurately. It is a new generation paint film tester that combines many advantages of traditional testing instruments at home and abroad, as well as the advantages of desktop, energy-saving, ultra wide workbench, and accurate temperature measurement. Excellent options and concept, all temperature sensors selected are platinum resistors imported from Germany, matched with a computer intelligent temperature regulator that combines fuzzy control theory and PID control to ensure display error is less than 0.5% ± 1. To reduce the size, our company spares no expense in using high-quality stainless steel shaped gradient plates and outer bodies. In order to reduce the noise of the refrigeration system, we have chosen semiconductor refrigeration and high-power stabilized switching power supplies.
