Milky-white quartz glass tube and heating materials in order that the elements have excellent farinfra-red radiativity after electrification ,the infrared and visible rays from heating material,97% are absorbed by satin silica glass tube and temperature of tube wall increases ,results in vibration of silicon-oxygen bond to radiate far infra-red rays. So that 97% visible and near infra-red rays may translate into far infra-red radiation and the problem when use only the transparent quartz glass will transparent visible and near infra-red rays is solved .The power effectively translates into far infra-red rays. It suit to heat the weave finalization printing and dyeing ,medicine and health and various industry.
