Heating of the device uses a separate heating unit for hot air circulation stove heating, hot air circulation takes the form of transverse fan, high heat exchange efficiency, increase circulation to maximize air flow to ensure uniform temperature of the furnace body sex; compact design of the device structure, reasonable layout, attractive appearance; low cost compared to similar foreign equipment.
Quartz glass is a silica glass in a single component. This glass can Ta Mok's hardness seven, with high temperatures, low coefficient of expansion, thermal shock resistance, good chemical stability and electrical insulation properties, and can through ultraviolet and infrared. In addition to hydrofluoric acid, hot phosphoric acid, in general have better acid resistance.
