Technical field
The invention belongs to flexible duct heating technique, especially relate to a kind of being combined for flexible duct heating
Insulation material.
Background technology
The heating of semiconductor vacuum pipeline has been widely used in many production process of semiconductor.Due to many half
In conductor manufacturing process, (such as CVD, PECVD, Etch) has the substantial amounts of generation coagulating product,
Heating to pipeline can avoid this type of product deposition on inner-walls of duct, thus, it is to avoid pipeline
Blocking, to ensure the properly functioning of semiconductor production equipment.The quasiconductor pipeline of one perfect heating can be big
Increase the utilization rate of oil (gas) filling device, extends the life-span of vacuum pump, improves the yield of finished product, and reduces operative employee
People and the contact of toxic gas.
Owing to pipeline regularly must be safeguarded, such as, replacement o circle, the pipeline heating of quasiconductor
Set allows for facilitating mounting or dismounting.This just significantly limit the use of insulation material.Especially must be to complexity
The heating of the parts (such as, valve) of shape.
Foamed silastic and glass fibre are the most the most frequently used insulation materials.Foamed silastic can be made non-
The heater of Chang Meiguan, but, its heat conductivity higher (about 0.1W/mK), therefore, heater
Surface temperature is higher, and heat dissipation capacity is the biggest.Such as some technique requires heat to 180 DEG C, surface temperature up to
90℃.This not only causes the loss of heat, and may cause the scald of operator.Glass fibre has
Relatively low heat conductivity, is widely used in the insulation of straight tube.But, owing to being difficult to that complex parts is wrapped
Cover.So the complex parts heater of employing glass fibre is the most ugly, and production cost is high.
Therefore, for the heating of semiconductor vacuum pipeline, how to improve the comprehensive heat-insulating property of heater with regard to pole
It is important.The challenge of the insulation of flexible heater always maximum.Because the material often flexibility of high insulation is relatively
Difference.And the material of flexibility has organic material often, not only non-refractory, and also flammable, security performance is relatively
Difference.
