Abstract
The present invention relates to a device for producing an aerogel blanket, and a method for producing an aerogel blanket. The device for producing an aerogel blanket according to present invention is a device for producing an aerogel blanket, including a supply part, which supplies a fiber containing sol, and a conveyor belt which moves the fiber supplied from the supply part, wherein the conveyor belt is provided in multiple levels to move the fiber while reversing the fiber, and a start time at which the conveyor belt reverses the fiber is before fluidity of the sol is completely lost.
Claims17
A device for producing an aerogel blanket, the device comprising:
- a supply part configured to supply a fiber containing sol;
- and
- a conveyor belt configured to move the fiber supplied from the supply part,
- wherein the conveyor belt is provided in multiple levels to move the fiber while reversing the fiber, and
- a start time at which the conveyor belt reverses the fiber is before fluidity of the sol is completely lost.
A method for producing an aerogel blanket, the method comprising:
- a supply process of supplying a fiber containing sol;
- and
- a moving process of moving, by a conveyor belt, the fiber supplied via the supply process,
- wherein, in the moving process, the conveyor belt is provided in multiple levels to move the fiber while reversing the fiber, and
- a start time at which the fiber is reversed in the moving process is before fluidity of the sol is completely lost.
An aerogel blanket comprising aerogel and a base material for a blanket, wherein the aerogel blanket has a combustion heat variation coefficient of about 0.130 or less according to following Equation 1:
- Combustion heat variation coefficient=[standard deviation of first combustion heat and second combustion heat (cal/g)/average of first combustion heat and second combustion heat (cal/g)] [Equation 1]
- wherein, in Equation 1 above, when the aerogel blanket is sliced to half thickness to be divided into a first surface and a second surface, the first combustion heat and the second combustion heat are measured according to ISO 1716 specification at the same position of the first surface and the second surface, respectively.
