| Advantages︰ | structure principle： SH Silica glass components for infrared beating elements used satin Silica glass tube and heating materials made in our company，in order that the elements have excellent far infra-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 glas5 Will transparent visible and near infrared rays is solved．The power effectively translates into far infra red rays．
Parameters：
A．For single SH infra-red silica glass heating element：voltage 220v，380v or others according to users requirement ，length 300-3000 mm， outside diameter Φ1050mm，power 300 6000W，or any other technique paramenters in need．
B．Surface temperature：low，middle and high temperature divided into three classes：
Low temperature class： 380480℃
middle temperature class： 500650℃
high temperature class 680750℃．
Or on customers request
C．Radiation characteristic：The kind Of heating elements has strong emission at far infrared waves，in comparison with other far infrared elements， at wavelength>6µ has the most strong radiation．
D．Spectrum emission：coating is no need for SH silica glass heating element， satin silica glass tube itself can play the role Of radiation and isolation，spectrum emissivity at wavelength>5µ ελ>0．9．
E．High emissivity， small thermal inertia<20sec， the thermoenergy is only 10% of silicon carbide and metal tubes，its very good for intermilent and continuous production |
