Introduction

When polymer lotion is used as a surface treatment agent for coatings, adhesives, chemical fiber fabrics, leather, paper and other surfaces, its film-forming property is one of the important technical indicators. Researchers are constantly improving their technical specifications and formulations in order to create new products with lower film-forming temperatures. Therefore, the film-forming temperature is detected(MFT)It is an important indicator of this type of coating, which can be easily measuredMFTThe ideal instrument isQMB-IIThe film-forming temperature measuring instrument has been developed.

QMB-IIType film-forming temperature measuring instrument(Abbreviated as low film)It is based on standardsGB9267-2008Designed and manufactured, 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, making it a leader among similar instruments.

according to the standardsThe technical specifications of GB9267-2008 instrument are as follows:

1. The working temperature range of the gradient plate can be adjusted freely between -7 ℃ and 70 ℃

2. Gradient board detection points: 13

3. Gradient interval: 20mm

4. Test coating tank: 6 strips, length 240mm, width 22mm (national standard 20-25mm), depth 0.25mm (national standard 0.20-0.30mm)

5. The inspection table shows that at 16:00, points 1-13 are the working gradient temperature, point 14 is the instrument environment temperature, and points 15 and 16 are the inlet and outlet temperatures of the cooling water
