Far nfrared Heating Technology and Status
1、The discovery of infrared radiation
Infrared radiation is usually called infrared. In ancient times,people have known the light and the heat of solar radiation. Up to 1676, Newton ,the Btritish, found the band of light of red, orange,Yellow, green, green, blue, purple - the solar spectrum, using the glass prism. In 1800, Hirsh, the British would like to measure the different color of sunlight to see which color have the most significant thermal effect of light ,so he repeated the experiment of Newton :
lead the sunlight to a dark room from a seam, let it pass through the glass prism, then a red, orange, yellow, green, blue,and purple colour light band appeared. He put a mercury thermometer respectively on every colourful light band colour,and at the same time he put other unused thermometer casually on the table .Once he came across that, in the dark, the temperature rise of the thermometer near to the red were much higher than that of thermometer on any other color.So he wrote to the Royal Society of Literature,he said“…there are at least a part of the heat of the sunlight are included in a invisible?light … ”After that,people called this “invisible??light” as infrared ray or infrared radiation.
2、The initial application stage abroad of the infrared heating technology
Althought the the discovery of infrared radiation are in the early 19th,the real widely used in industrial production, military and various scientific research is untill the World War II. In the 1930s, Ford Motor Company first applied the infrared radiation technology to the car paint drying process . At that time , the infrared lamp was used as the radiation source, due to restrictions of the glass shade, only one of the near-infrared energy were used. It was not until the Japanese developed the magnesium oxide and silicon carbide tube sheet, and promote the benefits of far infrared heating technology,that the technology attracted everyones atten
