什(shen)么是紅(hong)外線燈管?
紅外線(xian)燈(deng)管,也叫紅外線(xian)加熱燈(deng)管,是(shi)將鎢絲伸入充氣(qi)的石英(ying)(ying)管(guan)中(zhong)構成(cheng)。鎢絲在交(jiao)流電壓(ya)作(zuo)用(yong)下發(fa)熱并加熱石英(ying)(ying)管(guan)中(zhong)的氣(qi)體,由此產生紅外線輻射。 石英(ying)近紅(hong)外(wai)(wai)、遠(yuan)紅(hong)外(wai)(wai)燈采(cai)用透明(ming)或半透明(ming)石英(ying)玻璃作為燈管外(wai)(wai)殼(ke)可生產近紅(hong)外(wai)(wai)線或遠(yuan)紅(hong)外(wai)(wai)線輻射譜線。紅(hong)外(wai)(wai)線向(xiang)外(wai)(wai)輻射,可以用來加熱。
