A hot-melt line is a wire-shaped connecting material made of a heat-meltable polymer. When stapling, the temperature melts to a certain extent and sticks to the paper. The material used to make the hot-melt line is mainly polypropylene or polypropylene. Hot-melt line is mainly used for hot-melt line hot-stab (usually called plastic line hot-stab). When hot-stabbing, the hot-melt line is placed at the front-folding position of the folder, through the hot-head device equipped with the folding machine. , Reverse the hot-melt line on the creases of each signature, and heat them by the heating elements on the hot head - order the feet to melt and bind on the outer crease, and the other foot is painted on the back of the book. When the adhesive (or cover), the binding feet are bonded to each other and firmly joined together.
Hot-melt line bookbinding is an advanced process, but it has not been valued and popularized for various reasons. If this kind of process can be used universally, it can replace the sewing processing of sewing thread binding, sewing sewing, and iron wire binding, which can save a lot of manpower and material resources.

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.
