New flame retardant polyether polyol has been successfully developed

Huaihai Institute of Technology recently developed a polyether polyol with flame retardant properties. The flame-retardant polyol mainly uses N,N-bis(2-hydroxyethyl)-2,4,6-tribromoaniline as a starting material and propylene oxide as a flame-retardant monomer. Polyether polyols, used in polyurethane flexible foams, have good flame retardant properties and other physical and chemical properties. When the flame retardant polyether polyol has a direct fraction of 19%, the oxygen index of the obtained polyurethane foam product increases by more than 10%, and the other physical and chemical properties indexes also meet the requirements of GB/T2460-1993.

Mini Thermometer ZC-T01

All objects whose temperature is higher than absolute zero are constantly emitting infrared radiation energy into the surrounding space. The size of the infrared radiation energy of an object and its wavelength distribution are closely related to its surface temperature. Therefore, the surface temperature of the object can be accurately measured by measuring the infrared energy radiated by the object itself. This is the principle on which the infrared thermometer operates.
After the outbreak, measuring body temperature has become a convenient and intuitive way to find potentially infected people. Many regions require companies to prepare non-contact temperature measuring instruments when they resume work.
