Product Description:

Vokes® NPP (Nanoporous insulation panels)


Vokes® NPP is an evacuated micro porous thermal

insulating panel with excellent insulating properties.

Vokes® NPP 

The core material of

Vokes® NPP is fumed Silica board and noncombustible.

It is sealed into a high gas barrier film under vacuum.

Vokes® NPP 


Vokes® NPP is specially developed for insulation

applications where not much space is available but a

high thermal resistance is necessary. Mainly used in

high-temperature insulationMainly used in hightemperature


Vokes® NPP 

Vokes® NPP is a successful insulation element in the following areas:

• Industrial equipment insulation 

• High temperature boiler insulation 

• Thermal packaging (Medicine transport boxes, etc.)

• Appliance (Water boiler, etc.)

• Automotive (train, ship, air plains, etc.)


• Insulation : Long-term application temperature reached -120℃-1200℃. Insulation at normal

temperature for 3-5 times the performance of traditional materials. Stable thermal conductivity at high

temperatures, Temperature at 300 ℃ insulation performance is 4-8 times that of traditional materials.

• Drastically reduced insulation thickness 

• Thermal resistance :Particles constituting unit having a three-dimensional network structure,

will form many nanoporosity avoid sintering deformation.

• All purpose VIP with a long service life 

•Corrosion resistant :Products made of an inorganic material, no soluble chloride ions, No

corrosion on equipment, pipe grassroots.

• Soundproofing/Seismic Performance :Acoustic noise reduction, buffer shock.

• Waterproof :Product nanoparticles themselves with super hydrophobic properties.

Q:The relationship between fan power and air flow
The amount of air flowing per unit of time is used to indicate the capacity of the blower or ventilation equipment, calculated in cubic meters per second.
Q:Detailed description of the feed pump
To this end, 0.9Mpa 300 ℃ heating extraction steam into the back pressure small steam turbine, so that drag the feed pump, exhaust gas 0.1Mpa into the deaerator to feed water.
Q:What is the role of the water pump design of the warm pump system?
(1) due to higher water supply temperature, before the start if not fully warm pump, the pump temperature, uneven, there is the phenomenon of hot under the cool.
Q:What is the difference between a high-pressure ring fan and a Roots blower?
When the impeller rotates, due to the role of centrifugal force, the wind vane to promote the forward and outward movement of gas, thus forming a series of spiral movement.
Q:Usually the fan can be divided into several types
The fan is a mechanical fluid that relies on the input of mechanical energy, which increases the gas pressure and sends the gas to the gas. It is a driven fluid machine.
Q:What material is used for the fan
The main structural components of the fan are impeller, chassis, air inlet, bracket, motor, pulley, coupling, silencer, transmission (bearing) and so on.
Q:What is the difference between the function of the feed pump and the condensate pump?
And then return to the boiler. Is such a cycle of the process.
Q:What is the effect of the middle tap of the feed pump?
A pump is a machine that delivers liquid or pressurizes the liquid.
Q:Difference between air compressor and blower
2, the blower its air pressure is generally small (usually not more than 1kg / cm2), but its flow is relatively adequate, it is usually used in sewage or water treatment system, some production lines will be used, mainly for mixing.
Q:Calculation of wind pressure in wind blower
(2) dynamic pressure (Pv): the so-called dynamic pressure is the flow of fluid in the flow of the pressure formed by the pressure, often used in the kgf / m2 or mmaq to represent.
