SH Silica glass components for infra-red heating elements
SH 远红外石英加热元件


  一、结构原理: SH远红外石英加热元件采用我公司自己生产的石英乳白管配用电热材料,使原件具有优良可靠的远红外辐射特性:通电后

,电热材料发出的红外光与可见光中97%被乳白管所阻挡吸收使管壁温度升高产生硅氧键分子振动辐射远红外线,这样使97%可见光和近红外光可

转为远红外辐射。克服了单纯使用透明石英玻璃带来的透过可见和近红外的弊端,从而有效的使电能转化为远红外线。

  二、特 点:
SH远红外石英加热元件是以乳白石英管为红外辐射源,没有涂层,没有污染,没有有害辐射,化学稳定性极好,耐高温,形状

多样,长久使用不变形,热稳定性好,加热温度可自行选择。长期使用辐射性能不退变。并且使用寿命长,结构合理,热惯性极小,使用方便;

SH远红外石英加热器是国内唯一的选择性辐射远红外最好元件。

  三、主要技术参数:
SH远红外石英加热元件单支电压为220V,380V或用户需要其它电压等级。

1、 长度300-3,000mm;外径:Φ10-50mm;功率:300—6,000W。本公司还可按用户特殊要求的各项技术参数加工、设计、制造。

2、 表面温度分三档:低温:380℃——480℃ 中温:500℃——650℃ 高温:680℃—750℃

3、 相对辐射特性:该石英加热元件在远红外部分有较强的发射, 比起其他各类远红外原件,波长>6 μ 时,辐射能量尤为显著。

4、 光谱发射率:SH石英加热元件不需涂层,乳白管即起辐射作用,又起支撑绝缘作用,光谱发射率波长>5 μ 时,ε λ >0.9。

5、 辐射效率高,热惯性小,本身具有的热能量仅为碳化硅和金属管的10%,热惯性<20秒。特别适用于间歇式生产工艺,连续式更佳。

structure principle: SH Silica glass components for infra—red 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 infra—red 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 user's requirement ,length 300-3000 mm, outside diameter Φ10—50mm,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: 380——480℃
middle temperature class: 500——650℃
high temperature class 680——750℃.
Or on customer's request

C
.Radiation characteristic:The kind Of heating elements has strong emission at far infra—red waves,in comparison with other far infra—red elements, at wavelength>6 μ 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>5 μ ε λ >0.9.

E
.High emissivity, small thermal inertia<20sec, the thermo—energy is only 10% of silicon carbide and metal tubes,it's very good for intermilent and continuous production.
